Profiling the physicochemical and solid state properties of edible Tetracarpidium conophorum oil and its admixtures for drug delivery

Abstract The study is aimed at investigating the functional physicochemical and solid state characteristics of food-grade Tetracarpidium conophorum (T. conophorum) oil for possible application in the pharmaceutical industry for drug delivery. The oil was obtained by cold hexane extraction and its physicochemical properties including viscosity, pH, peroxide, acid, and thiobarbituric acid values, nutrient content, and fatty acid profile were determined. Admixtures of the oil with Softisan®154, a hydrogenated solid lipid from palm oil, were prepared to obtain matrices which were evaluated by differential scanning calorimetry, fourier-transform infrared spectroscopy, and x-ray diffractometry. Data from the study showed that T. conophorum oil had Newtonian flow behaviour, acidic pH, insignificant presence of hyperperoxides and malondialdehyde, contains minerals including calcium, magnesium, zinc, copper, manganese, iron, selenium, and potassium, vitamins including niacin (B3), thiamine (B1), cyanocobalamine (B12), ascorbic acid (C), and tocopherol (E), and long-chain saturated and unsaturated fatty acids including n-hexadecanoic acid, 9(Z)-octadecenoic acid, and cis-13-octadecenoic acid. The lipid matrices had low crystallinity and enthalpy values with increased amorphicity, and showed no destructive intermolecular interaction or incompatibility between T. conophorum oil and Softisan® 154. In conclusion, the results have shown that, in addition to T. conophorum oil being useful as food, it will also be an important excipient for the development of novel, safe, and effective lipid-based drug delivery systems.

Evaluation of copaiba oil as enhancer of ibuprofen skin permeation

Abstract The administration of medications on the skin through transcutaneous routes is a practice that has been used by mankind for millennia. Some studies have been reporting the use of terpenes and natural oils rich in terpenes as an enhancer of cutaneous penetration. Copaiba oil, due to its rich content of terpenes, presents itself as a great choice of penetration enhancer for drugs administered on the skin. In this study, we developed two cream formulations containing 5% of ibuprofen (IBU) and copaiba oil: IBCO5 and IBCO10 with 5% and 10% of copaiba oil respectively. Ex vivo cutaneous penetration/permeation studies of IBU were performed using pig ear skin as biological membrane in the Franz-type diffusion cells. The steady-state flux of IBU samples, IBCO5 (35.72 ± 6.35) and IBCO10 (29.78 ± 2.41) were significantly higher when compared with control without copaiba oil (10.32 ±1.52) and with a commercial product (14.44 ± 2.39). In the penetration analysis, the amount of IBU found in the samples IBCO5 and IBCO10 was markedly higher in the dermis than epidermis. Our results showed that copaiba oil possesses attracting properties in promoting skin penetration and permeation of IBU when added into cream formulations.

Aceites esenciales con actividad antibacteriana: posible aplicación y administración en odontología / Essential oils with antibacterial activity: possible uses and administration in the dental practice

Resumen Introducción la caries dental es una de las enfermedades de mayor prevalencia a escala mundial, cuyas consecuencias clínicas se encuentran relacionadas directamente con la calidad de vida de los individuos. Asimismo, la atención odontológica exige un elevado costo y muchas veces lejos del alcance de ciertas comunidades. Si bien esta enfermedad se produce por la confluencia de distintos factores, uno de ellos es el económico, por lo que se busca una opción medicinal de bajo costo, y el abordaje a su vez de otro factor, tal vez el más importante, que implica el desarrollo y multiplicación del microorganismo iniciador de esta enfermedad, que es Streptococcus mutans. Actualmente se conoce el consumo de medicinas de origen natural para el tratamiento de algunas enfermedades, entre ellas, la caries. El uso y mecanismo de acción de aceites esenciales que impidan el desarrollo de S. mutans en el biofilm dental está siendo investigado. El objetivo de este trabajo es actualizar los conocimientos sobre la acción biocida de aceites esenciales y sus posibles aplicaciones en odontología. Resultados. Los aceites esenciales provenientes de los cítricos como limón, mandarina, naranja, como así también de eucalipto y orégano, presentan actividad bacteriostática, y en algunos casos, bactericida frente a bacterias Gram + y Gram -. Conclusión de acuerdo con la información recopilada, el uso de estos aceites mediante la biotecnología sería beneficioso y contribuiría al manejo de la salud bucal sin alterar la microflora oral normal del ser humano.

Abstract Dental caries is one of the most prevalent diseases worldwide, whose clinical consequences are directly related to the quality of life of individuals. Likewise, dental care requires a high cost and is often beyond the reach of certain communities. Although this disease is produced by the confluence of different factors, one of them is the economic factor, which is why a low-cost medicinal alternative is sought, and the approach in turn of another factor, perhaps the most important, which implies the development and multiplication of the initiating microorganism of this disease that is Streptococcus mutans. Currently, the consumption of medicines of natural origin is known for the treatment of some diseases, including tooth decay. The use of essential oils that prevent the development of St. mutans in dental biofilm is being investigated and the objective of this work is to update the knowledge about its biocidal action and its applications in dentistry. The objective of this work is to update the knowledge on the biocidal action of essential oils and their possible applications in dentistry. Results The essential oils from citrus fruits such as lemon, mandarin, orange, as well as eucalyptus and oregano, show bacteriostatic activity, and in some cases, bactericidal against Gram + and Gram - bacteria. Conclusion according to the information collected, the use of these oils through biotechnology would be beneficial and would contribute to the management of oral health without altering the normal oral microflora of the human being.

Negative impacts of mining on Neotropical freshwater fishes

Mining activities have significantly affected the Neotropical freshwater ichthyofauna, the most diverse in the world. However, no study has systematized knowledge on the subject. In this review, we assembled information on the main impacts of mining of crude oil, gold, iron, copper, and bauxite on aquatic ecosystems, emphasizing Neotropical freshwater fishes. The information obtained shows that mining activities generate several different disturbances, mainly via input of crude oil, metals and other pollutants, erosion and siltation, deforestation, and road construction. Mining has resulted in direct and indirect losses of fish diversity in several Neotropical waterbodies. The negative impacts on the ichthyofauna may change the structure of communities, compromise entire food chains, and erode ecosystem services provided by freshwater fishes. Particularly noteworthy is that mining activities (legal and illegal) are widespread in the Neotropics, and often located within or near protected areas. Actions to prevent and mitigate impacts, such as inspection, monitoring, management, and restoration plans, have been cursory or absent. In addition, there is strong political pressure to expand mining; if - or when - this happens, it will increase the potential of the activity to further diminish the diversity of Neotropical freshwater fishes.(AU)

As atividades de mineração têm impactado significativamente a ictiofauna de água doce Neotropical, a mais diversa do mundo. Porém, nenhum estudo sistematizou o conhecimento sobre o assunto. Nesta revisão, reunimos informações sobre os principais impactos da mineração de petróleo, ouro, ferro, cobre, e bauxita sobre os ecossistemas aquáticos, com ênfase nos peixes de água doce Neotropicais. As informações obtidas mostram que as atividades de mineração geram diferentes distúrbios, principalmente por meio de petróleo bruto, metais e outros poluentes, erosão e assoreamento, desmatamento e construção de estradas. A mineração resultou em perda direta e indireta de diversidade de peixes de vários corpos d'água Neotropicais. Os impactos negativos sobre a ictiofauna podem alterar a estrutura das comunidades, comprometer cadeias alimentares inteiras, bem como degradar os serviços ecossistêmicos fornecidos pelos peixes de água doce. Particularmente importante é que as atividades de mineração (legais e ilegais) são generalizadas na região Neotropical, e frequentemente estão localizadas dentro ou perto de áreas protegidas. Ações de prevenção e mitigação de impactos, como planos de fiscalização, monitoramento, manejo e restauração, têm sido precárias ou ausentes. Além disso, há forte pressão política para expandir a mineração; se - ou quando - isso acontecer, aumentará o potencial da atividade em diminuir ainda mais a diversidade de peixes de água doce Neotropicais.(AU)

Effect of long-term consumption of oxidized polyunsaturated fatty acids on atherosclerotic lesion in LDL receptor knockout mice / Efeito do consumo crônico de ácidos graxos poliinsaturados oxidados na aterosclerose em camundongos knockout para receptor de LDL

Polyunsaturated fatty acids (PUFA) are susceptible to enzymatic and non-enzymatic oxidation, leading to the production of secondary compounds that present different physiological effects. Among the PUFA, the products formed from Omega 6 (n-6 FA) and Omega 3 (n-3 FA) fatty acids oxidation can modulate inflammation, dyslipidemia and oxidative stress preventing or reducing the atherosclerosis progression. In fact, the effect of chronic intake of edible oils containing products of polyunsaturated fatty acids oxidation (POPs) on atherosclerosis is still controversial. In general POPs from n-6 FA have a more pro-inflammatory profile than POPs from n-3 FA. Thus, the objective of this study was to compare the chronic intake of partially oxidized n-6 FA and n-3 FA rich oils on atherosclerosis biomarkers. Initially, six edible oils containing a higher amount of n-6 and n-3 FA were submitted to oxidative conditions, simulating the steps of transport, storage and consume. It was observed that oxidative reaction started in all oils since the first step and at the moment of consumption, some oxidative chemical markers were out the legal range suggested by the Official Agencies. In addition, it was possible to identify the type of secondary product formed from each precursor oil, providing a better information for oils quality control. After this step, fish and soybean oils were chosen as n-3 FA and n-6 FA rich oils, respectively. Using LDLr(-/-) mice, the effect of three oxidative levels of soybean oil was evaluated after 24 weeks of supplementation. Animals fed with the oil with the highest level of oxidation (fried and reused oil) showed no body weight gain, suggesting that POPs from soybean oil at this level could promote a browning effect on white adipose tissue by increasing UCP-1 expression. This group also showed the highest concentration of lipoproteins in plasma. However, these metabolic differences did not accelerate atherosclerosis in the animals. Finally, the effect of POPs from n-3 FA and n-6 FA oxidation were compared also using LDLr(-/-) mice as model for experimental atherosclerosis. Some alterations observed after n-3 FA supplementation, such as the increase of liver weight, IL-6, SONPC, 8-HETE and 15-F2-Isop and the decrease of BAT and glucose, were reversed by their POPs. In addition, POPs from n-6 FA caused increased of LDL and 5-HETE. As observed in the previous study, these metabolic alterations were not enough to prevent or accelerate atherosclerosis, as measured by histological analysis of the lesion size in the aorta. These results suggest that although a significant amount of POPs are being consumed by diet, their metabolic effects did not influence atherosclerotic plaques in the animal model. However, besides lesion area in the aortas, new studies should also evaluate the plaques stability

Os ácidos graxos poliinsaturados (PUFA) são suscetíveis à oxidação enzimática e não enzimática, levando à produção de compostos secundários que apresentam diferentes efeitos fisiológicos. Entre os PUFA, os produtos formados a partir da oxidação dos ácidos graxos ômega 6 (n-6 FA) e ômega 3 (n-3 FA) podem modular a inflamação, dislipidemia e estresse oxidativo, impedindo ou reduzindo a progressão da aterosclerose. De fato, o efeito da ingestão crônica de óleos contendo produtos da oxidação de ácidos graxos poliinsaturados (POPs) na aterosclerose ainda é controverso. Em geral, os POPs dos n-6 FA têm um perfil mais pró-inflamatório do que os POPs dos n-3 FA. Assim, o objetivo deste estudo foi comparar a ingestão crônica de POPs provenientes de óleos ricos em n-6 FA e n-3 FA em biomarcadores de aterosclerose. Inicialmente, seis óleos ricos em n-6 FA e n-3 FA foram submetidos a condições oxidativas, simulando as etapas de transporte, armazenamento e consumo. Observou-se que a reação oxidativa iniciou-se em todos os óleos desde a primeira etapa e, no momento do consumo, alguns marcadores oxidativos estavam fora da faixa legal sugerida pelas agências reguladoras. Além disso, foi possível identificar o tipo de produto secundário formado a partir de cada óleo precursor, fornecendo melhores informações para o controle de qualidade dos óleos. Após esta etapa, os óleos de peixe e soja foram escolhidos como óleos ricos em n-3 FA e n-6 FA, respectivamente. Utilizando camundongos LDLr(-/-), o efeito de três níveis oxidativos de óleo de soja foi avaliado após 24 semanas de suplementação. Os animais alimentados com o óleo com maior nível de oxidação (óleo frito e de reuso) não apresentaram ganho de peso corporal, sugerindo que os POPs do óleo de soja nesse nível de oxidação pudessem promover um efeito de Browning no tecido adiposo branco, aumentando a expressão de UCP-1. Este grupo também mostrou a maior concentração de lipoproteínas no plasma. No entanto, essas diferenças metabólicas não aceleraram a aterosclerose nos animais. Finalmente, o efeito de POPs da oxidação de óleos ricos em n-3 FA e n-6 FA foi comparado também usando camundongos LDLr(-/-), como modelo para aterosclerose experimental. Algumas alterações observadas após a suplementação com óleo de peixe fresco, como aumento do peso hepático, IL-6, SONPC, 8-HETE e 15-F2-IsoP e diminuição da BAT e glicose, foram revertidas por seus POPs. Além disso, os POPs do óleo de soja causaram aumento de LDL e 5-HETE. Como observado no estudo anterior, essas alterações metabólicas não foram suficientes para prevenir ou acelerar a aterosclerose, medida pela análise histológica do tamanho da lesão na aorta. Esses resultados sugerem que, embora uma quantidade significativa de POPs esteja sendo consumida pela dieta, seus efeitos metabólicos não influenciaram as placas ateroscleróticas no modelo animal. Porém, além da área de lesão nas aortas, novos estudos também devem avaliar a estabilidade das placas

Single cell oil production by a novel yeast Trichosporon mycotoxinivorans for complete and ecofriendly valorization of paddy straw

Background: Oleaginous yeasts can be grown on different carbon sources, including lignocellulosic hydrolysate containing a mixture of glucose and xylose. However, not all yeast strains can utilize both the sugars for lipogenesis. Therefore, in this study, efforts were made to isolate dual sugar-utilizing oleaginous yeasts from different sources. Results: A total of eleven isolates were obtained, which were screened for their ability to utilize various carbohydrates for lipogenesis. One promising yeast isolate Trichosporon mycotoxinivorans S2 was selected based on its capability to use a mixture of glucose and xylose and produce 44.86 ± 4.03% lipids, as well as its tolerance to fermentation inhibitors. In order to identify an inexpensive source of sugars, nondetoxified paddy straw hydrolysate (saccharified with cellulase), supplemented with 0.05% yeast extract, 0.18% peptone, and 0.04% MgSO4 was used for growth of the yeast, resulting in a yield of 5.17 g L−1 lipids with conversion productivity of 0.06 g L−1 h−1 . Optimization of the levels of yeast extract, peptone, and MgSO4 for maximizing lipid production using Box­Behnken design led to an increase in lipid yield by 41.59%. FAME analysis of single cell oil revealed oleic acid (30.84%), palmitic acid (18.28%), and stearic acid (17.64%) as the major fatty acids. Conclusion: The fatty acid profile illustrates the potential of T. mycotoxinivorans S2 to produce single cell oil as a feedstock for biodiesel. Therefore, the present study also indicated the potential of selected yeast to develop a zero-waste process for the complete valorization of paddy straw hydrolysate without detoxification

Chemical composition, antimicrobial and antioxidant activity of the essential oil of leaves of Eugenia involucrata DC / Composição química, atividade antimicrobiana e antioxidante do óleo essencial das folhas de Eugenia involucrata DC

In the Myrtaceae family, the species Eugenia involucrata DC., popularly known as "cerejeira-do-mato", is traditionally used for the antidiarrheal and digestive action of its leaves. However, no studies were found in the literature regarding its antimicrobial and antioxidant potential. In this context, the objective of the present study was to determine the chemical composition by gas chromatography coupled to mass spectrometry (GC-MS) to evaluate the antimicrobial activity by the broth microdilution technique and the antioxidant activity by the 2,2-diphenyl-1-picryl-hydrazila (DPPH) method of the essential oil of E. involucrataleaves. GC-MS identified 28 compounds, all sesquiterpenes, corresponding to 89.41% of the essential oil. The antimicrobial activity of the essential oil was observed for all Gram-positive bacteria tested (Staplylococcus epidermidis, Enterococcus faecalis,Bacillus subtilis and Staplylococcus aureus) and for yeast Candida albicans. The essential oil presented a reduction capacity of DPPH up to 66.81%, evidencing its antioxidant potential. It is suggested that the antimicrobial and antioxidant action of E. involucrata essential oil is related to the presence of the major compounds, elixene (26.53%), ß-caryophyllene (13.16%), α-copaene (8.41%) and germacrene D (7.17%).

Na família Myrtaceae, a espécieEugenia involucrata DC. popularmente denominada "cerejeira-do-mato" é conhecida tradicionalmente pela ação antidiarreica e digestiva de suas folhas. Contudo, na literatura não foram encontrados trabalhos referentes ao seu potencial antimicrobiano e antioxidante. Neste contexto, o objetivo do presente estudo foi determinar a composição química por cromatografia gasosa acoplada a espectrometria de massas (CG-EM) e avaliar a atividade antimicrobiana pela técnica de microdiluição em caldo e a atividade antioxidante pelo método do 2,2-difenil-1-picril-hidrazila (DPPH) do óleo essencial das folhas de E. involucrata. A CG-EM identificou 28 compostos, todos sesquiterpenos, correspondendo a 89,41% do óleo essencial. A atividade antimicrobiana do óleo essencial foi observada para todas as bactérias Gram-positivas testadas (Staplylococcus epidermidis, Enterococcus faecalis,Bacillus subtilise Staplylococcus aureus) e para a levedura Candida albicans. O óleo essencial apresentou capacidade redutora de radicais DPPH de até 66,81%, evidenciando sua potencialidade antioxidante. Sugere-se que a ação antimicrobiana e antioxidante do óleo essencial de E. involucrata esteja relacionada à presença dos compostos majoritários, elixeno (26,53%), ß-cariofileno (13,16%), -copaeno (8,41%) e germacreno D (7,17%).

Determinación de la rancidez en aceites usados en el proceso de frituras en establecimientos de expendió de comida rápida / Determination of rancity in oils used in the frying process in fast food display establishments

INTRODUCCIÓN: en la actualidad se ha producido un incremento sustancial del consumo de alimentos procesados en frituras con aceites vegetales expedidos en establecimientos de comida rápida, que son de elección para muchas personas principalmente por trabajadores y estudiantes por el horario limitado con el que cuentan para su alimentación y muchas veces por temas de economía. OBJETIVO: determinar la rancidez en aceites usados en el proceso de frituras en establecimientos de comida rápida. MÉTODOS: se implementaron la Prueba de Kreiss (método cualitativo) y el Índice de Peróxidos (método cuantitativo) para cuantificar la rancidez en los aceites utilizados para el procesamiento de frituras. RESULTADOS: de un total de 12 muestras de aceite analizadas, se estableció que el 42 % se encuentran fuera del rango establecido según la Norma Boliviana (NB 34008) lo que confirma el uso de aceites rancios.

INTRODUCTION: at present there has been a substantial increase in the consumption of processed foods in fried foods with vegetable oils issued in fast food establishments, which are the choice for many people, mainly by workers and students due to the limited hours they have for their food and often for economic reasons. OBJECTIVE: to determine the rancidity in oils used in the frying process in fast food establishments. METHODS: the Kreiss Test (qualitative method) and the Peroxide Index (quantitative method) were implemented to quantify rancidity in the oils used for frying processing. RESULTS: from a total of 12 oil samples analyzed, it was established that 42% are outside the range established according to the Bolivian Standard (NB 34008), which confirms the use of rancid oils. CONCLUSIONS: with the applied methods, Kreiss (qualitative) and Peroxide Index (quantitative) the same results were obtained, however, the use of the quantitative method is recommended because the Standard defines a limit of up to 6 meq / Kg, and the Qualitative method can be subjective because it is defined by a color change, likewise in the study the use of rancid oils in fast food outlets was confirmed.

Influência do tipo do óleo nas propriedades físicas de oleogéis / Influence of oil type on the oleogels physical properties

A crescente rejeição às gorduras saturadas e trans em decorrência de sua associação com doenças cardiovasculares, entre outras desordens metabólicas de diversas naturezas, tem impulsionado o desenvolvimento de alternativas às gorduras tradicionalmente utilizadas nos processamentos de alimentos. Contudo, o grande desafio reside em conferir funcionalidade tecnológica a lipídios ricos em ácidos graxos insaturados, sendo os oleogéis uma abordagem viável e promissora. Os oleogéis são sistemas constituídos por uma base lipídica composta por óleo no estado líquido estruturada por uma rede tridimensional de moléculas com solubilidade limitada em óleos, chamadas de agentes estruturantes. Estudos recentes relataram a influência do tipo de óleo no processo de formação da rede tridimensional de agentes estruturantes e concluíram que o tamanho da cadeia, a polaridade e a viscosidade do óleo podem afetar grandemente a estrutura do oleogel. Diante disto, o objetivo deste estudo é investigar a influência do tipo de óleo em sua estruturação por cera de candelilla, relacionando as propriedades físicas dos oleogéis formados com diversas características físico-químicas dos óleos que os compõem. Para avaliar esta influência, foram selecionadas bases lipídicas de diferentes composições, como triacilgliceróis de cadeia média (MCT), óleo de girassol alto oleico (HOSO), óleo de girassol (SFO), óleo de linhaça (LSO) e os óleos unicelulares ARASCO e DHASCO, para serem estruturados com cera de candelilla nas concentrações de 1,5, 3,0 e 6,0%. De acordo com as correlações de Pearson estabelecidas, houve uma correlação muito forte (r2 =0,948) entre a firmeza e o conteúdo de ácidos graxos saturados dos óleos, o que pode estar relacionado a uma co-cristalização entre a cera e os ácidos graxos saturados, formando uma estrutura mais firme. Uma correlação forte também foi estabelecida entre o tamanho médio das cadeias de ácidos graxos dos óleos, definido pelo índice de saponificação, e a firmeza dos oleogéis (r2 =0,864). A densidade dos óleos também apresentou correlação forte com a firmeza dos oleogéis (r2 =0,858), assim como a viscosidade apresentou uma forte correlação negativa (r2 = -0,818), o que indica que os óleos mais densos e menos viscosos produzem oleogéis mais firmes. Tanto a cera de candelilla pura quanto os oleogéis apresentaram forma polimórfica ß', que equivale à subcélula ortorrômbica, que demonstra que os diferentes óleos não modificaram a microestrutura da rede de cera de candelilla. Os diferentes tipos de óleo exerceram influência sobre o comportamento de fusão dos oleogéis, fator que permitiu associá-lo a um maior conteúdo de gordura sólida a 20 °C e a um maior teor de triacilgliceróis trissaturados, como nos óleos DHASCO e ARASCO. O grau de insaturação dos óleos influenciou o empacotamento da rede estrutural dos oleogéis, o que foi revelado pela menor perda de óleo nos oleogéis com cadeias mais longas, se comparados ao MCT. Por fim, este trabalho contribuiu com a expansão do conhecimento dos sistemas chamados oleogéis, sugerindo que trabalhos futuros pautem as escolhas de matéria-prima para formulação dos oleogéis nas propriedades de seus componentes. Desta forma, maiores avanços poderão ser alcançados nas pesquisas de sistemas coloidais e consequentemente no desenvolvimento de sistemas de alta qualidade nutricional e, ao mesmo tempo, funcionalidade tecnológica adequada

The growing rejection of saturated and trans fats as a result of their association with cardiovascular diseases, among other metabolic disorders of various kinds, has driven the development of alternative systems to substitute fats traditionally used in food processing. However, the big challenge lies in providing technological functionality to lipids rich in unsaturated fatty acids, with oleogels being a viable and promising approach. Oleogels are systems made up of a lipid base composed of oil in a liquid state structured by a threedimensional network of molecules with limited solubility in oils, called oleogelators. Recent studies have reported the influence of the oil type in the formation process of the threedimensional network of oleogelators and concluded that the fatty acid chain length, the polarity and the viscosity of the oil can greatly affect the structure of the oleogel. In view of this, the objective of this study is to investigate the influence of the oil type in its structuring by candelilla wax, relating the physical properties of the formed oleogels with several physicochemical characteristics of the oils that compose them. To evaluate this influence, lipid bases of different compositions were selected, such as medium chain triglycerides (MCT), high oleic sunflower oil (HOSO), sunflower oil (SFO), linseed oil (LSO) and ARASCO and DHASCO single-cell oils, to be structured with candelilla wax in concentrations of 1.5, 3.0 and 6.0% (w/w). According to the Pearson correlations established, there was a very strong correlation (r2 = 0.948) between the firmness and the saturated fatty acid content of the oils, which may be related to a co-crystallization between the wax and the saturated fatty acids, forming a firmer structure. A strong correlation was also established between the average size of the fatty acid chains of the oils, defined by the saponification value, and the oleogel firmness (r2 = 0.864). The density of the oils also showed a strong correlation with the firmness of the oleogels (r2 = 0.858), as well as the viscosity, which showed a strong negative correlation (r2 = -0.818), indicating that oils with higher density and lower viscosity produce firmer oleogels. Both pure candelilla wax and oleogels presented the ß' polymorphic form, which is equivalent to the orthorhombic subcell, demonstrating that the different oils did not modify the microstructure of the candelilla wax network. The different types of oil influenced the melting behavior of oleogels, a factor that allowed it to be associated with a higher solid fat content at 20 °C and a higher content of trisaturated triacylglycerols, as in DHASCO and ARASCO oils. The degree of unsaturation of the oils influenced the packaging of the structural network of oleogels, which was revealed by the higher oil binding capacity in oleogels with longer chains, compared to MCT. Finally, this work contributed to the expansion of knowledge of oleogel systems, suggesting that future work will guide the choices of raw material for formulating oleogels in the properties of their components. Thus, greater advances can be achieved in the research of colloidal systems and, consequently, in the development of high nutritional quality systems allied to adequate technological functionality

Avaliação do estado oxidação dos óleos de abacate, azeite e arroz / Oxidation state evaluation of the avocado, olive and rice oils

O estado de oxidação é um importante aspecto relacionado à qualidade nutricional e sensorial dos óleos vegetais, que pode limitar a utilização dos mesmos. Assim, objetivou-se com este estudo avaliar o estado oxidação de óleo de abacate produzido nacionalmente, comparativamente a azeite de oliva extra virgem e a óleo de arroz refinado. Avaliaram-se nos produtos os índices de peróxidos, p-anisidina e coeficiente de extinção específica (K232 e K270). Os resultados indicaram que, de um modo geral, as amostras lipídicas mostravam bom estado de conservação, tanto em relação a produtos primários quanto secundários de oxidação. Entretanto, com base na legislação para azeite de oliva, pode-se inferir que o óleo de arroz apresentava elevado valor para produtos de oxidação secundários, expressos pelo K270. O óleo de abacate mostrou os mais baixos valores em todas as determinações realizadas, portanto, indicando estar em ótimo estado de conservação em relação à presença de produtos de oxidação.

Os resíduos do processamento de frutas, como o melão, têm se tornado um problema para as agroindústrias, pois são gerados em grandes quantidades e podem provocar danos ao meio ambiente quando descartados inadequadamente. Diante disto, o objetivo deste trabalho foi estudar a influência da torrefação no rendimento de óleo das sementes de melão obtido por extração assistida por ultrassom. Para tanto, as sementes foram caracterizadas físico-quimicamente, e o rendimento de óleo foi estudado em relação à temperatura e o tempo de torrefação, utilizando um fatorial 22 com blocos casualizados. Os resultados mostraram que a temperatura e o tempo de torrefação influenciaram no rendimento do óleo de sementes de melão, sendo que os maiores rendimentos de óleo foram obtidos nas condições de 89 ºC por 53 minutos e de 131 ºC por 17 minutos.

Food and nutrient intake status of Korean elderly by perceived anxiety and depressive condition: data from Korean National Health and Nutrition Examination Survey 2013 ~ 2015 / 한국영양학회지

PURPOSE: This study examined the food and nutrient intake of Korean elderly according to the anxiety and depressive condition using the data from the Korea National Health and Nutrition Survey (KNHANES) from 2013 to 2015. METHODS: The participants were 3,504 elderly people over 65 years of age (1,523 in men and, 1,981 in women). The dietary information was analyzed using the 24-hour recall data. The anxiety and depressive state was assessed using the self-reported scale EQ-5D in the quality of life dimension. The subjects were divided into the anxiety · depression group (AD) and non-anxiety · depression group (NAD) according to their anxiety and depressive conditions. RESULTS: In the male elderly, the AD group had a significantly lower education and economic level and higher proportion in living alone than the NAD group. The percentage of eating lunch and dinner alone in the male AD group was higher than that of the NAD group. The female AD group showed less a lower frequency of dinner than the NAD group. The male AD group had a lower consumption of total foods, fish and shellfishes, seaweeds, mushrooms, oils and fats, and seasonings than the NAD group. With regard to the nutrient intake, the male elderly NAD group had more sufficient nutrient intakes than the AD group. In particular, the daily intakes of dietary fiber, riboflavin, niacin, potassium and iron were significantly lower in the AD group. To compare with the nutrient density of the two groups, the vitamin C and niacin intakes were lower in the AD group than in the NAD group. Overall, the nutritional status of the male AD group was significantly lower than that of the NAD group. Meanwhile, the female elderly had showed a smaller difference in nutrient intake according to their anxiety and depressive condition. CONCLUSION: These results of this study show that more nutritional education and emotional support are needed to improve the nutritional status and health of the male elderly with anxiety or depression.

Avaliação da presença do 3-monocloro-1, 2-propanediol e glicidol em óleos vegetais comestíveis utilizando GC/MS/MS e seu risco toxicológico / Evaluation of the presence of 3-monochloro-1, 2-propanediol and glycidol in edible vegetable oils using GC/MS/MS and its toxicological risk

Cloropropanóis são um grupo conhecido de contaminantes relacionados ao processamento de alimentos. Eles são formados na reação entre lipídeos e cloretos quando submetidos ao tratamento térmico, e podem ser encontrados na forma livre ou ligada. O 3-monocloro-1,2-propanediol (3-MCPD), é classificado pela IARC como possível carcinógeno humano (grupo 2B). O glicidol (e seus ésteres), é classificado também pela IARC como uma substância provavelmente carcinogênica para seres humanos (grupo 2A), e, recentemente, vem sendo encontrado em alimentos. O objetivo deste trabalho foi avaliar a presença do 3-MCPD e do glicidol em óleos vegetais comestíveis utilizando a cromatografia gasosa com detector de massa triplo quadrupolo MS/MS. A técnica utilizada foi a preconizada pela AOCS Cd 29c-13, sendo uma análise indireta, e foi possível adaptá-la visando as determinações do 3-MCPD e glicidol através da construção de curvas de calibração e análises de amostras de referência. O método foi validado e os resultados indicaram o limite de detecção do composto 3-MCPD, de 42,4 µg/kg e o limite de quantificação de 50 µg/kg, e para o Glicidol indicaram o limite de detecção de 43,5 µg/kg e limite de quantificação de 50 µg/kg. Os resultados para 3-MCPD obtidos nos ensaios da curva de calibração e linearidade demonstraram que o método foi capaz de expressar resultados com boa linearidade (0 - 10 mg/kg , r2, = 0.9991). Os resultados obtidos nos ensaios de exatidão obedeceram aos critérios de 70 a 120% de recuperação, e ±20% de variação entre os resultados de acordo com SANTE (2017). O método em questão demonstrou ser seletivo, uma vez que não foram observados picos interferentes nos tempos de retenção dos compostos estudados. Os ensaios de precisão nos níveis baixos, médio e alto e robustez demonstraram que o método é robusto e preciso, portanto a validação foi considerada adequada ao uso pretendido. Foram analisadas 368 amostras de óleos vegetais (76 amostras de óleo de canola, 48 amostras de óleo de milho, 69 amostras de óleo de algodão, 33 amostras de óleo de palma, 10 amostras de óleo de palmiste, 50 amostras de oleína de palma, 30 amostras de óleo de soja e 51 amostras de óleo de girassol). As concentrações das amostras analisadas apresentaram resultados para 3-MCPD com valores médios entre 203 a 1205 µg/kg. Para o Glicidol os valores foram de 2 a 1198 µg/kg, com elevado o desvio padrão entre os resultados analíticos, onde o óleo de palma apresentou a maior variação de 1600 a 5260 µg/kg. Através da avaliação do risco realizada para o composto 3-MCPD foi possível detectar, utilizando o critério do pior cenário de exposição e resultados analíticos, os valores diários de consumo de óleo de algodão de 0,044 µg/kg p.c., de óleo de girassol 0,045 µg/kg p.c., óleo de canola 0,18 µg/kg p.c., óleo de palma de 0,28 µg/p.c, óleo de milho de 0,0462 µg/kg p.c., e o óleo de soja, de maior consumo no Brasil (72%) apresentou o valor de 0,27 µg/kg p.c. O consumo de todos estes óleos, pela a população brasileira, pode ser considerado seguro ao comparar com o valor de TDI Ingestão Diária Tolerável - de 2µg/kg p.c.. Através da avaliação do risco realizada também utilizando o critério de pior cenário de exposição e e resultados analíticos para o composto glicidol foi possível verificar que os valores diários de consumo de óleo de algodão de 0,061 µg/kg p.c., de óleo de girassol 0,03 µg/kg p.c., óleo de canola 0,13 µg/kg p.c. e de óleo de palma de 0,57 µg/p.c, de óleo de milho de 0,11 µg/kg p.c, e o óleo de soja de maior consumo no Brasil (72%) não ultrapassam o valor de 0,288 µg/kg p.c indicando consumo seguro destes óleos para a população brasileira baseado na TDI de 1000µg/kg p.c

Chloropropanols are a known group of contaminants related to food processing. They are formed during the reaction process between lipids and chlorides when submitted to heat treatment and can be found in free or bound form. The 3-monochloro-1,2-propanediol (3-MCPD), is classified by IARC as a possible human carcinogen (group 2B). Glycidol (and its esters), also classified by IARC as a substance likely to be carcinogenic to humans (group 2A), has recently been found in food. The present study aims to evaluate the presence of 3-MCPD and glycidol in edible vegetable oils using gas chromatography with triple quadrupole MS/MS mass detector. The technique applied is recommended by AOCS, guide Cd 29c-13, an indirect analysis, and allows quantification of 3-MCPD and glycidol by building the calibration curves and analysis of reference samples. The method was validated and the detection limit of the contaminant 3-MCPD of 42,4 µg/kg and the quantification limit of 50 µg/kg was established. For Glycidol the detection limit of was 43,5 µg/kg and quantification limit was 50 µg/kg. The results obtained in the calibration and linearity curves demonstrated that the method could express results with good linearity (0 10 mg/kg, r2, = 0.9991). The results obtained in the trueness trials agreed to the criteria of 70 to 120% of recovery, and ± 20% of variation between the results according to what is preconized by SANTE (2017). The method showed to be selective, since no interfering peaks were observed in the retention times of the studied compounds. The tests performed on low, medium and high values demonstrated the robustness and precision of the method, so the validation was considered completed and suitable for the purpose. A total of 368 vegetable oil samples were analyzed (76 samples of canola oil, 48 samples of corn oil, 69 samples of cottonseed oil, 33 samples of palm oil, 10 samples of kern palm oil, 50 samples of palm olein, 30 samples of soybean oil and 51 samples of sunflower oil). The results found in samples for 3-MCPD were within mean values between 203 and 1205 µg/kg. The results found in samples for glycidol were within mean values between 2 to 1198 µg/kg where palm oil presented the highest variation for glycidol from 1600 to 5260 µg/kg. Through the risk assessment for the contaminant 3-MCPD it was possible to detect the values based on exposed worst case scenario and analytical results. The results for cottom oil were 0,044 µg/kg bw, sunflower 0,045 µg/kg bw, canola 0,18 µg/kg bw and palm oil 0,28 µg/kg bw, corn oil 0,0462 µg/kg bw, and for soybean, which is the most consumed oil in Brazil (72%) the value of 0,27 µg/kg bw. These results indicates safe consumption for these oils based in the Theoretical Daily Ingestion - TDI of 2µg/kg bw. The risk assessment for the glycidol based on exposure worst case scenario and analytical results presented for cottom oil the value of 0,061 µg/kg bw, sunflower 0,03 µg/kg bw, canola oil 0,13 µg/kg bw , palm oil 0,57 µg/kg bw, corn oil 0,11 µg/kg bw and for soybean, which is the most consumed in Brazil - 72% the value of 0,27 µg/kg bw. These results indicates safe consumption for these oils based in the TDI of 1000µg/kg bw

Associations between the dietary patterns of pregnant Malaysian women and ethnicity, education, and early pregnancy waist circumference: A prospective cohort study

BACKGROUND/OBJECTIVES: Little is known about the dietary patterns (DPs) of women during pregnancy. The present study aimed to identify the DPs of pregnant Malaysian women and their associations with socio-demographic, obstetric, and anthropometric characteristics. SUBJECTS AND METHODS: This prospective cohort study included 737 participants enrolled in Seremban Cohort Study between 2013 and 2015. Food consumption was assessed using a validated 126-food item semi-quantitative food frequency questionnaire (SFFQ) at four time-points, namely, pre-pregnancy and at each trimester (first, second, and third). Principal component analysis (PCA) was used to identify DPs. RESULTS: Three DPs were identified at each time point and designated DP 1–3 (pre-pregnancy), DP 4–6 (first trimester), DP 7–9 (second trimester) and DP 10–12 (third trimester). DP 1, 4, and 7 appeared to be more prudent diets, characterized by higher intakes of nuts, seeds & legumes, green leafy vegetables, other vegetables, eggs, fruits, and milk & dairy products. DP 2, 5, 8, and 11 had greater loadings of condiments & spices, sugar, spreads & creamer, though DP 2 had additional sweet foods, DP 5 and 8 had additional oils & fats, and DP 11 had additional tea & coffee, respectively. DP 3 and 6 were characterized by high protein (poultry, meat, processed, dairy, eggs, and fish), sugars (mainly as beverages and sweet foods), and energy (bread, cereal & cereal products, rice, noodles & pasta) intakes. DP 9 had additional fruits. However, DP 12 had greater loadings of energy foods (bread, cereal & cereal products, rice, noodles & pasta), sugars (mainly as beverages, and sweet foods), and good protein sources (eggs, nuts, seeds & legumes). Malays were more likely to have lower adherence (LA) for DP 1 and 10 than non-Malays. DP 2, 8, and 11 were more prevalent among Malays than non-Malays. Women with a higher education were more likely to have LA for DP 10, and women with a greater waist circumference at first prenatal visit were more likely to show LA for DP 11. CONCLUSIONS: DPs observed in the present study were substantially different from those reported in Western populations. Information concerning associations between ethnicity, waist circumference and education with specific DPs before and throughout pregnancy could facilitate efforts to promote healthy dietary behavior and the overall health and well-being of pregnant women.

Essential Oil of Marrubium vulgare: Chemical Composition and Biological Activities. A Review

Marrubium vulgare, plant species belonging to Marrubium genus, is widespread in the Mediterranean areas, introduced elsewhere and also cultivated in many countries. Its oil is recognized to possess a considerable biological activities with varied chemical composition. This paper aims to overview the chemical composition and biological activities of M. vulgare essential oil's considered as a medicinal plant, widely used in folk medicine overall the world. In essential oils of M. vulgare, germacrene D, β-caryophyllene, β-bisabolene, bicyclogermacrene and carvacrol are generally considered as either mains or minor constituents and each species presents its own composition. Sesquiterpenoids were the dominant fraction while monoterpenoids were present in appreciable or in trace amount. Oxygenated fractions dominated in monoterpenes however, hydrocarbon fraction overpowered in sesquiterpenes. These oils are biologically active, they exhibit an antioxidant and antimicrobial activities and other activities. Due to the variability of composition of essential oil, further studies are necessary, particularly regarding their chemical's which may cause an important change in the biological activities of oils and probably defined different chemotype.

Protective effect of dietary oils containing omega-3 fatty acids against glucocorticoid-induced osteoporosis / 한국영양학회지

PURPOSE: Glucocorticoids (GCs) are implicated in secondary osteoporosis, and the resulting fractures cause significant morbidity. Polyunsaturated fatty acids (PUFAs) play a vital role in bone metabolism. However, few trials have studied the impact of omega-3 PUFA-containing oils against GC-induced osteoporosis. Therefore, the present study was undertaken to determine whether supplementation with omega-3 PUFA-containing dietary oils such as fish oil, flaxseed oil or soybean oil can impede the development of GC-induced osteoporosis. METHODS: The fatty acids (FAs) content of oils was determined using gas chromatography. Male rats were subdivided into 5 groups (8 rats each): normal control (balanced diet), prednisolone control (10 mg/kg prednisolone daily), soybean oil (prednisolone 10 mg/kg + soybean oil 7% w/w), flaxseed oil (prednisolone 10 mg/kg + flaxseed oil 7% w/w), and fish oil (from cod liver; prednisolone 10 mg/kg + fish oil 7% w/w). RESULTS: The study data exhibited a significant depletion in bone mineral density (BMD) and femur mass in the prednisolone control compared to the normal control, accompanied with a marked decrease in the levels of plasma calcium and 1,25-(OH)₂-vitamin D₃, and elevated levels of C-terminal telopeptide (CTX), tumor necrosis factor-alpha (TNF-α) and malondialdehyde (MDA). Supplementation with fish oil, soybean oil or flaxseed oil helped to improve plasma calcium levels, and suppress oxidative stress and inflammatory markers. Additionally, bone resorption was suppressed as reflected by the decreased CTX levels. However, fish oil was more effective than the other two oils with a significant improvement in BMD and normal histological results compared to the normal control. CONCLUSION: This study demonstrated that supplementation with dietary oils containing omega-3 PUFAs such as fish oil, soybean oil or flaxseed oil can play a role in the prevention of bone loss and in the regulation of bone metabolism, especially fish oil which demonstrated a greater level of protection against GC-induced osteoporosis.

Food Intake Behavior in Cancer Survivors in Comparison With Healthy General Population; From the Health Examination Center-based Cohort

BACKGROUND: This study aimed to investigate the food intake behavior of cancer survivors based on main sources of energy intake from different food groups in comparison with healthy individuals.METHODS: Baseline survey data from the Health Examinee cohort, which recruited participants from 2014 to 2013 were applied. A total of 5,269 cancer survivors and 5,219 healthy subjects without comorbidities who were matched by age, sex, and enrollment center were included in the analysis. The proportion of energy intake for 17 food groups was devided into lower median and median or upper. OR and 95% CIs were determined to measure the difference of energy intake proportion in cancer survivors, five major types of cancer survivors versus healthy individuals.RESULTS: Generally, the proportion of calories intake from sugars and sweets, meat and poultry, oils and fats, and beverage was lower in cancer survivors than in healthy individuals (OR = 0.83 [95% CI = 0.79–0.88], 0.75 [95% CI = 0.71–0.80], 0.84 [95% CI = 0.80–0.89], and 0.93 [95% CI = 0.88–0.99], respectively) with more prominently shown in breast, colon, and thyroid cancer individuals. In contrast, cancer survivors tended to intake calories from potatoes and starches, legume, seeds and nuts, vegetables, mushrooms, fruits, and seasonings more than healthy individuals (OR = 1.09 [95% CI = 1.03–1.16], 1.13 [95% CI = 1.06–1.19], 1.15 [95% CI = 1.09–1.22], 1.07 [95% CI = 1.01–1.13], 1.07 [95% CI = 1.02–1.14], 1.15 [95% CI = 1.08–1.21], and 1.17 [95% CI = 1.10–1.23], respectively) which were more prominent in gastric and breast cancer survivors.CONCLUSIONS: The dietary behavior measured by main sources of energy intake in cancer survivors was different from healthy individuals in terms of several food groups. Although there are nutrition guidelines for cancer survivors, because of the differences between Western population and Asian people in terms of food culture, the guidelines for balanced nutritious behavior should be established among Asian cancer survivors.

Dietary intakes and obesity of Malaysian adults

BACKGROUND/OBJECTIVES: Over the past few decades, Malaysia has been experiencing an increased prevalence of overweight and obesity that threatens the health of Malaysians. Poor dietary intake is one of the major contributors to the development of obesity and many non-communicable diseases. The dietary intakes of adults in Malaysia were assessed to determine the association between the dietary intake variables and the body mass index (BMI) and waist circumference (WC) measurements. This study examined whether the dietary intake achieved the recommended nutritional guidelines and compared the intakes between both sexes. SUBJECTS/METHODS: The height, weight, and WC of four-hundred-and-ninety adults (n = 490) in Malaysia were measured using standard procedures. The three-day 24-hour dietary recalls were conducted on 422 out of the 490 adults and their dietary intakes were evaluated in detail. The selected dietary intake variables were used to determine the associations with the obesity indicators. RESULTS: Among the participants, 52.8% were overweight or obese. After data analysis, the mean energy intake was 1,550 kcal/day, in which male participants had a significantly higher energy and macronutrients intake than females. Protein consumption and its percentage of energy contribution exceeded the recommended range. The consumption of fruits, vegetables, and milk and milk products were lower than the recommended number of servings for a healthy diet. The male participants consumed significantly more servings of carbohydrate-based foods, meat, and fats, oils, and sweets than females. Among the selected dietary intake variables, only the carbohydrate intake was negatively associated with the BMI (Estimate b = −0.008) and WC measurements (Estimate b = −0.019) after adjusting for covariates. CONCLUSIONS: This study evaluated the dietary intakes of a sample of Malaysian adults and its association with the obesity indicators. The results highlight the need for improvements and modifications of the dietary intake of Malaysians to reduce the overweight and obesity rates.
