ABSTRACT

Introduction: An ideal clearing agent should remove alcohol from the tissue specimens to enable the penetration of paraffin wax which provides sturdiness to the tissue specimen. Xylene has toxic effects and is still used because of its accurate clearing property and maintaining the staining quality. Natural alternatives to xylene provide a less toxic environment for histopathological technicians. Aim: The study is to evaluate the accuracy of clarified butter as xylene substitute in routine histopathological tissue processing procedure. Materials and Methods: 40 paired soft tissue specimens were obtained from the Department of Oral pathology and microbiology and subjected to routine histopathological tissue processing with xylene and ghee as clearing agents. Post processing, the tissue specimens were immersed in paraffin wax overnight, embedded, sectioned and stained using hematoxylin and eosin. Histopathological criteria namely nuclear staining, cytoplasmic staining, artefacts and background staining were evaluated and the scores were tabulated and statistical analysis was done using SPSS version 20 by IBM. Results: Our study results showed that tissue specimens processed in xylene and ghee had similar nuclear staining. In cytoplasmic staining, tissue specimens processed in ghee had superior results than xylene processing. Artefacts were present more in xylene processing than ghee processing. Background staining was more appreciated in xylene processed tissue specimens than ghee processing. Conclusion: Substituting xylene with ghee showed better results as a clearing agent in routine histopathological tissue processing. Ghee as a clearing agent is non toxic, cost effective compared to xylene and a safer alternative.

ABSTRACT

Based on the UHPLC-Q-Exactive-MS metabonomics technology, the effect of Hippocampus kuda Bleeker on the life span of Drosophila melanogaster was studied, and the change rule of endogenous metabolites in the aging process of Drosophila melanogaster after the intervention of Hippocampus kuda Bleeker japonicus was explored to clarify the anti-aging mechanism of Hippocampus. The natural aging model of Drosophila melanogaster was used. Different doses of raw Hippocampus and fried Hippocampus were given to observe the effects on the life span, climbing ability, sexual activity, and antioxidant enzyme activity of Drosophila melanogaster. Based on UHPLC-Q-Exactive-MS metabolomics technology, the metabolic profile of the aging Drosophila melanogaster was analyzed using metabonomics technology to explore the mechanism of Hippocampus kuda Bleeker delaying the aging of Drosophila melanogaster. The results showed that raw Hippocampus and crispy Hippocampus (1, 4 mg·mL-1) could significantly prolong the average life span, median life span and maximum life span of male fruit flies, and significantly improve the climbing ability and sexual vitality of fruit flies. Catalase (CAT) and aldehyde content were increased, while malonaldehyde (MDA) content was decreased. Through metabonomics technology, it was identified that the Hippocampus can significantly recall 16 metabolites and participate in the biosynthesis of phenylalanine, tyrosine and tryptophan, starch and sucrose metabolism, tyrosine metabolism, cysteine and methionine metabolism, and histidine metabolism. The anti-aging mechanism is related to amino acid metabolism and sugar metabolism, which provides a substantial scientific basis for the development and utilization of Hippocampus and clarifying its role in senile diseases. The animal experiment of this study was approved by the Ethics Committee of Shanxi University (approval number: SXULL2021028).

ABSTRACT

Parikartika is one of the common ano-rectal anomalies observed in clinical practise. In Ayurveda Samhitas, this condition is mostly mentioned as an Upadrava of Grahani, Atisara, Arshas and as Vamanavirechanavyapat. ‘Kartanavatvedhana’ is described as predominant symptom of Parikartika which means cutting type of pain in the anus. As per the description of signs and symptoms, Parikartika can be co-related to fissure-in ano in modern contexts. Yashtimadhu is the most widely used drug for Parikartika. Acharya Susruta has mentioned the drug Yashtimadhu in Trividhakarma Adhyaya in post-operative pain management and in treatment for Parikartika in Vamana virechana vyapat. Yashtimadhu in the form of Thaila and Ghrita are commonly used. Here, Yashtimadhuchurna was used to prepare a suppository with cocoa butter as its base for the management of Parikartika. Objectives: The objective of the clinical study is to evaluate any difference in the efficacy of Yashtimadhu suppository in treating Parikartika. Materials and Methods: The study was conducted as an open labelled, randomized, single arm clinical study. 40 Patients who are fulfilling the inclusion, exclusion, diagnostic criteria and complying with the informed consent was selected from OPD and IPD of Sri Jayendra Saraswathi Ayurveda College and Hospital [IEC NO- IEC/ SJSACH/ 09/2021, CTRI NO- CTRI/2021/07/035252]. Case proforma was prepared with all the appropriate details of the patient along with history and physical, rectal examination was done to diagnose Parikartika. Relevant laboratory investigations were performed. Yashtimadhu suppository was given twice per day for about 14 days to 40 patients along with 4 follow-ups once a week for one month after the treatment i.e., 7th, 14th, 21st, 28th day. The subjective parameter was pain and objective parameter were ulceration, sphincter tone. Grading was done according to the specified assessment criteria and was statistically analysed. Results: On completion of the study, statistical analysis was done on the data collected. The intervention, Yashtimadhu suppository showed significant difference in the outcome.

ABSTRACT

Using technical procedures, the fatty acid (FA) profile and solid fat content (SFC) of the Peruvian cultivar cacao beans CCN 51 and ICS 6 and the "optimal chocolate", obtained from the mixture of the first two, were determined to assess their quality. These cacao beans were found to have important nutritional values. The FA profile of the cacao beans were similar (p>0.05); however, in the FA profile, the 'optimal chocolate' had significant differences (p≤0.05) in terms of palmitic, arachidic and linolenic acid. The n6:n3 ratio for "optimal chocolate" was 12.0 ± 1.7. Cacao beans had the same SFC, and SFC was highly temperature dependent, as determined using a mathematical model for chocolate. The SFC of chocolate refers to hard cacao butter content at temperatures between 20 and 25°C, and solid fat was heat resistant from 25 to 30°C, which is considered valuable in trade chocolate production. The quality-related properties of these lipid fractions imparted nutritional and physical aspects to the optimal dark chocolate for human consumption.


La composición de ácidos grasos (CAG) y el contenido de sólidos grasos (CSG), de la fracción lipídica de los cultivares peruanos de cacao CCN 51 e ICS 6 así como del "chocolate óptimo", obtenido de las mezclas de las primeras dos, fueron determinados por técnicas analíticas para conocer su calidad. Estas variedades tuvieron valores nutricionales importantes. La CAG de los granos de cacao fueron similares, sin embargo la CAG del "Chocolate óptimo" tuvo diferencias significativas (p<0,05) para los acidos grasos palmitico, araquidico y linoleico. El ratio n6:n3 fue de 12,0 ± 1,7. El CSG de los granos de cacao fueron los mismos y tuvo una fuerte dependencia con la temperatura, también se definió un modelo matematico para el chocolate. El CSG le confiere al chocolate una consistencia dura a temperaturas de 20 a 25°C y resistentes al calor de 25 a 30°C, siendo tales propiedades una ventaja en la comercialización de chocolates. La calidad de estas fracciones lipidicas tuvieron aspectos nutricionales y fisicos en el chocolate oscuro para consumo humano.

O leite, a porção sólida e a manteiga produzida foram avaliadas quanto a sua caracterização físico-química. O leite apresentou 8,75% de gordura, 7,12% de proteína, 3,90% de lactose e 21,11% de extrato seco total. O pH, acidez titulável e densidade relativa do colostro foram de 6,38, 27,17ºD e 1,038 g mL-1, respectivamente. O teor de gordura da porção sólida foi de 27,33%, seu peso de 2,24 kg e o peso da manteiga produzida foi de 1,13 kg a partir de 10 litros de colostro de ovelha. A manteiga apresentou 59% de gordura, 2,56% de acidez titulável, 0,96 de atividade de água e índice de ácido tiobarbitúrico de 0,13 mg kg-1. Estes resultados indicam que a silagem de colostro possui potencial tecnológico adequado para produção de manteiga

ABSTRACT

La alteración de los lípidos en sangre o dislipidemias sobre todo el colesterol y triglicéridos, son un factor de riesgo de ateroesclerosis y enfermedades cardiovasculares. En este trabajo se analizó el efecto del consumo de huevo, clara, yema de huevo, mantequilla y maní sobre el perfil lipídico de ratones sanos. Se utilizaron seis grupos de ratones hembras sanas, el grupo control (GC) recibió balanceado comercial, mientras que en los demás grupos, 15% de su alimentación diaria consistió en huevo entero (GHE), yema (GY), clara de huevo (GCH), manteca o mantequilla (GMT) o maní (GMN), durante 28 días. Al final de este periodo, se obtuvo la muestra de suero para la determinación de los niveles de colesterol total (CT), triglicéridos (TG), colesterol HDL, colesterol LDL y colesterol VLDL, y se calcularon los índices de riesgo aterogénico y de riesgo cardiaco. Se observó un aumento estadísticamente significativo en los niveles de CT y LDL en relación al GC en los grupos GHE (p<0,0001), GY (p<0,0001), GCH (p<0,005) y GMT (p<0,001), mientras que en niveles de TG presentan un aumento los grupos GHE (p<0,0001) y GY (p<0,0001). El nivel de HDL aumentó significativamente en los grupos GHE (p<0,005) y GMT (p<0,001), y en cuanto al índice de riesgo cardiaco y aterogénico el grupo GY fue el único que reveló aumento significativo (p<0,0001). En el grupo que recibió maní (GMN), no se alteraron los niveles de lípidos, y por lo tanto tampoco el riesgo cardiaco ni aterogénico, lo que se traduce en un menor riesgo de enfermedades cardiovasculares de este grupo(AU)


The alteration of blood lipids or dyslipidemias, especially cholesterol and triglycerides, are a risk factor for atherosclerosis and cardiovascular diseases. In this work, the effect of consumption of egg, egg white, egg yolk, butter and peanut on the lipid profile of healthy mice was analyzed. Six groups of healthy female mice were used, the control group (GC) received commercial pellets, while for the other groups, 15% of their daily food consisted of whole egg (GHE), egg yolk (GY), egg white (GCH) ), butter (GMT) or peanut (GMN), for 28 days. At the end of this period, a serum sample was obtained for the determination of the levels of total cholesterol (CT), triglycerides (TG), HDL cholesterol, LDL cholesterol and VLDL cholesterol, and cardiac and atherogenic risk index were calculated. A statistically significant increase in TC and LDL levels was observed in relation to GC in the GHE (p <0,0001), GY (p <0,0001), GCH (p <0,005) and GMT (p <0,001) groups; whereas TG levels showed an increase in the GHE (p <0,0001) and GY (p <0,0001) groups. The HDL level increased significantly in the groups GHE (p <0,005) and GMT (p <0,001), and in terms of the cardiac and atherogenic risk index, the GY group was the only group that revealed a significant increase (p <0,0001). In the group that received peanuts (GMN), the lipid levels were not altered, and therefore neither the cardiac nor the atherogenic risk, which indicates the risk of cardiovascular diseases in this group, were affected(AU)

ABSTRACT

RESUMO A avaliação de ciclo de vida (ACV) é uma técnica de estimativa de impactos ambientais, como emissão de gases de efeito estufa (CO2eq), para geração de produto ou realização de processo. O objetivo deste estudo foi estabelecer a pegada de carbono para a produção da margarina e da manteiga com uso das normas ISO e PAS aplicadas a uma empresa de alimentos localizada na região Sul do Brasil desde a etapa do campo até a sua forma embalada com unidade funcional de 500 g para distribuição. Três cenários foram abordados para a margarina (óleos de soja provenientes do Sul e do Centro-Oeste com e sem desmatamento por queimada) e dois para manteiga (com alocação por massa e econômica). A modelagem foi realizada com dados primários de produção agrícola e da empresa e secundários do ecoinvent ® . A pegada da manteiga com alocação econômica (2,91 kg de CO2eq) foi maior do que a da margarina produzida com soja da mesma região (1,32 kg de CO2eq). Entretanto, esse coproduto autônomo da indústria de laticínio requer alocação mássica para evitar supervalorização, sendo de fato a menor pegada (0,63 kg de CO2eq). A utilização de grãos de soja do Centro-Oeste aumentou a pegada da margarina (1,58 kg de CO2eq), tendo sido muito intensificado quando empregado desmatamento por queimada (2,69 kg de CO2eq). A produção de leite foi o fator deletério preponderante para a manteiga. Para a margarina, houve duas situações distintas, sua fabricação quando se usa soja da mesma região ou a produção do grão quando este for proveniente de região distante desmatada por queimada.


ABSTRACT Life Cycle Assessment is a technique for estimating environmental impacts, such as the emission of greenhouse gases (CO2eq), for manufacturing product or process realization. The objective of this study was to establish the carbon footprint for the production of margarine and butter using ISO and PAS standards applied to a food company, located in the southern region of Brazil, from the field stage to its packed form with a functional unit of 500 g for distribution. Three scenarios were addressed for margarine (soybean oil from the South and the Midwest with and without burned deforestation) and two for butter (with mass and economic allocation). The modeling was performed with primary data from the agricultural and industrial production, and secondary data from ecoinvent ® . The economically allocated butter footprint (2.91 kg CO2eq) was higher than that of margarine produced with soybeans from the same region (1.32 kg CO2eq). However, this autonomous co-product of the dairy industry requires mass allocation to avoid overvaluation, being in fact the smallest footprint (0.63 kg CO2eq). The use of soybeans from the Midwest increased margarine' footprint (1.58 kg CO2eq) and was greatly intensified with burned deforestation (2.69 kg CO2eq). Milk production was the predominant deleterious factor for butter. For margarine there were two other distinct occasions, which were the manufacture when soy from the same region is used or the production with soybeans from a distant region deforested by burning.

ABSTRACT

The fruits of Persea Americana Mill., commonly known as Avocado, are traditionally consumed for various health benefits including weight reduction. Here, we studied the effect of hydroalcoholic fruit extract of Persea americana (HAEPA) on high fat diet (HFD) induced obesity in rats. Obesity was induced in male Sprague Dawley rats by feeding HFD for 14 wk. The hypolipidemic effect was evaluated by co-administering 25, 50, 100 and 200 mg/kg body wt. of HAEPA. There was a significant increase in weight gain, body mass index (BMI), blood lipids, low density lipoproteins (LDL), lipid peroxides (LPO) and serum transaminases in HFD fed rats. HFD+HAEPA fed rats showed a significant decrease in blood lipids, LPO, liver lipids and increase in antioxidant status when compared to HFD control rats. The activity of lipid metabolic key enzymes such as fatty acid synthase and HMG CoA reductase in liver were also found to be decreased significantly in HAEPA co-administered rats. Lipoprotein lipase activity was found increased in HFD+HAEPA rats. Among the 4 doses studied, 100 mg of HAEPA/kg body wt. exhibited optimum hypolipidemic activity. Histopathological observations in liver and visceral adipose tissue added more evidence for the lipid lowering effect of HAEPA. It can be concluded that avocado fruit extract can act as hypolipidemic agent probably by modulating the activities of HMG CoA reductase and fatty acid synthase in liver.

ABSTRACT

We performed an oral food challenge (OFC) with 10 g of butter (equivalent of 2.9 mL cow's milk) and 25-mL heated cow's milk for 68 children with cow's milk-allergy. Thirty-eight children reacted only to heated cow's milk. Twenty-four children reacted to neither heated milk nor butter. Thirty-eight (86.4%) of 44 patients with positive results to the OFC for heated milk could safely tolerate butter. It is highly likely that even children with cow's milk-allergy who show positive results to an OFC for heated milk can consume butter. The milk-specific IgE value indicative of a negative predictive value of over 95% was 17.8 kUA/L, and patients with low milk-specific IgE values may be able to safely consume butter. Including butter in the diets of patients with milk-allergy after a butter challenge may improve quality of life.

ABSTRACT

The importance of diet in maintaining health is widely accepted and recognized. Diet lipid profile is important to prevent chronic diseases and improve the quality of life of individuals. The objective of this study was to analyze the effect of different sources of dietary lipids with normal and high concentration, on the fatty acid profile of growing rats. Experimental diets contained 15 and 40% kcal from fat, provided by butter (B), olive oil (O), high oleic acid sunflower oil (SO) and sunflower oil (S). Control diet (C) was normocaloric, with 15%kcal of fat provided by soy oil. All diets were complete in the others nutrients and were administered for 40 days. Daily intake was similar in all groups. B, O and SO groups had increased serum oleic acid and a decrease in serum essential fatty acids with respect to C. These results are seen independent of the fat proportion (F%) of the diet. S group showed an increase in linoleic acid only when F% was 40. The administration of these diets provoked changes in serum fatty acid profile levels in response to the differences sources of dietary lipids used; only some changes observed in S group were in response to the high fat percentage.


El perfil de lípidos de una dieta es importante para prevenir enfermedades crónicas y mejorar la calidad de vida de los individuos. Objetivo: estudiar el efecto de dietas con diferentes fuentes y concentraciones lipídicas sobre el perfil de ácidos grasos en suero de ratas en período de crecimiento activo. Las dietas experimentales, contenían 15 y 40 Kcal% de lípidos aportados por: manteca (M); aceite de oliva (O); aceite de girasol alto oleico (AO) y aceite de girasol (G). El control recibió dieta normocalórica (fuente lipídica: aceite de soja). Los grupos M, O y AO presentaron un aumento en los niveles séricos del ácido oleico, con disminución de los ácidos grasos esenciales (AGE) con respecto al grupo C. Estos resultados se observan independientemente del F% de la dieta. El grupo G muestra aumento de ácido linoleico sólo cuando el F% de la dieta fue 40. La administración de estas dietas provocó cambios en el perfil de ácidos grasos en suero en respuesta a las diferentes fuentes aportadas por las dietas, sólo algunos cambios observados en el grupo G fueron también en respuesta al alto porcentaje de grasa.

ABSTRACT

A method was developed for the determination of eight steroid hormones ( estrone, α/β-estradiol, estriol, testosterone, epitestosterone, progesterone and testosterone propionate ) in butter samples by gel permeation chromatography ( GPC) purification-followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The samples were first extracted by ethylacetate/cyclohexane (1:1, V/V) and the extract was later degreased by GPC column. Then, the GPC concentrate was separated using a C18 column ( 100 mm í2. 0 mm i. d. , 3. 0 μm) with gradient elution of acetonitrile/water. Finally, the steroid hormone components were qualitatively and quantitatively determined by mass spectrometer with electrospray ionization in multi reaction monitoring mode. Using matrix matched external standard method, good linearity in response could be obtained in the concentration range of 1 . 0-20 . 0 μg/kg with correlation co-efficiency larger than 0 . 999 . The detection limits of the method were 0. 04-0. 30 μg/kg and the quantification limit was 1. 0 μg/kg. At the spike levels of 1. 0, 2. 0 and 4. 0μg/kg, the recoveries of hormones were within the range of 64. 1%-110%, and the relative standard deviation ( RSD) was less than 11%. The results show that the method is accurate and reliable, and meets the requirements for determination of 8 steroid hormones in butter samples.

ABSTRACT

Demand for dietary fibre-enriched and low sugar bakery products is rapidly increasing due to the current high incidence of Type 2 diabetes mellitus. Cinnamon, a spice which acts as a natural sweetener and insulin mimetic is believed to have health benefits. The objective of this study was to determine the properties of butter biscuits containing cinnamon powder (CP) that partially replaced sucrose at levels of 0 (control), 2, 4 or 6%. Methods: Nutritional composition, physical properties and sensory acceptability of the biscuits were analysed using AOAC methods, texture profile analyser and 7-point hedonic scaling method, respectively. Results: Protein, ash and dietary fibre contents of the biscuits increased significantly (P < 0.05) whereas the moisture and sucrose contents were reduced significantly, proportionately to the increasing levels of CP. In texture profile analyses, increment of firmness and reduction of crispiness of the biscuits were detected with increasing levels of CP, but not significantly. The sensory scores for control and 2% CP biscuits were not significantly different for all the sensory attributes. Biscuits with 4% CP received lower scores only for aroma and appearance whereas the scores for colour, crispiness and flavour showed no significant differences compared to the control and 2% CP biscuit. Conclusion: The addition of 4% CP in biscuit could be an effective way to produce nutritious butter biscuits without any apparent change to its desirable physical properties and sensory acceptability.

ABSTRACT

Aims: To elucidate the effect of estrogen and folic acid on high fat (butter) induced lipid profile (total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), and triglyceride (TG)) and on tissue texture changes in mice. Designs: Randomized block design. Place and Duration of Study: Department of Physiology and Department of Pathology, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh between January 2012 and April2012. Methodology: 2 months old 50 male Swiss Albino mice (Mus musculus) were used for this study and divided into equal groups. Group A (control) was fed with normal rat pellet. Mice in the group B was fed with butter; group C was fed with butter and estrogen; group D was fed with butter and folic acid and group E was fed with butter, estrogen and folic acid. The atheroprotective effect of estrogen and folic acid was evaluated based on weight gain, biochemical parameters and histopathology. Results: The highest body weight gain was detected in group B (P<0.001). In biochemical study, group B showed the increase in total plasma cholesterol, especially low density lipoprotein (LDL), and triglyceride (TG) (P<0.001) compared to other treated groups. Group C, D and E showed a lower level of total plasma cholesterol (P<0.001) compared to group B. Among them group E showed the lowest total plasma cholesterol level (P<0.001). In histopathological study, the aorta of butter treated group showed sloughing of lining endothelium, increased aortic wall thickness and loss of integrity of tunica intima. It also revealed fatty changes in liver in animal models fed with butter, compared with those on a normal diet. Conclusions: 20% butter supplementation would be able to cause a rise in lipid profile and produce degenerative changes in aorta and liver and addition of estrogen or folic acid in butter supplemented diet counteracts the adverse effect.

ABSTRACT

Rising global demand for natural products whose production is harmless to the environment has stimulated the development of natural cosmetics and, within this category, organics (95% organic raw materials). The image of environmentally friendly production is one of the strongest attractions of organic products. Lip balm is a cosmetic product similar to lipstick whose purpose is to prevent lip dryness and protect against adverse environmental factors. The product's characteristics are: resistance to temperature variations, pleasant flavor, innocuousness, smoothness during application, adherence and easy intentional removal. This work involved the development of a lip balm formulated with certified organic raw materials and the execution of stability tests: fusion point determination, evaluation of organoleptic characteristics (color, odor and appearance) and functionality evaluation (spreadability test). The formulation selected after the Preliminary Stability Test was submitted to the Normal Stability Test under the following storage conditions (temperature): Room Temperature (22.0 ± 3.0 ºC), Oven (40.0 ± 2.0 ºC) and Refrigerator (5.0 ± 1.0 ºC), for 90 days. Under the Refrigerator and Room Temperature conditions, spreadability proved adequate, but the surface presented white spots, characterizing the fat bloom, a phenomenon involving the recrystallization of cocoa butter. Storage at 40.0 ± 2.0 ºC (Oven) caused loss of functionality according to the spreadability test, in addition to changes in color, although the aspect was uniform since the fat bloom was not observed (white spots on the surface). The odor remained stable under all conditions as did the melting point, which had a mean of 72.9 ± 1.7 ºC throughout the course of stability testing (90 days).


O aumento da demanda global por produtos naturais, cuja produção não envolva nenhum dano ao meio ambiente, tem estimulado o desenvolvimento de cosméticos naturais e, dentro desta categoria, dos produtos orgânicos (que contêm 95% de matérias-primas orgânicas). O protetor labial é um produto cosmético semelhante ao batom que tem a finalidade de prevenir o ressecamento dos lábios, mantendo a hidratação, e protegê-los contra fatores ambientais adversos. Este trabalho envolveu o desenvolvimento de um protetor labial formulado com matérias-primas orgânicas e avaliação dos parâmetros de estabilidade, como ponto de fusão, características organolépticas e funcionalidade (teste de espalhabilidade). A formulação selecionada após o Estudo de Estabilidade Preliminar foi submetida à Avaliação Normal de Estabilidade, nas seguintes condições de armazenamento (temperatura): Ambiente (22,0 ± 3,0 ºC), Estufa (40,0 ± 2,0 ºC) e Geladeira (5,0 ± 1,0 ºC), por 90 dias. Nas condições de armazenamento em geladeira ou ambiente, a espalhabilidade foi adequada, mas a superfície apresentou pontos esbranquiçados, caracterizando o fenômeno chamado fat bloom, que está relacionado à recristalização da manteiga de cacau. O armazenamento à temperatura elevada (40,0 ± 2,0 ºC) provocou perda de funcionalidade, de acordo com o teste de espalhabilidade, e mudança de cor, apesar do aspecto permanecer uniforme, visto que não foi observado o fenômeno fat bloom. O odor manteve-se estável em todas as condições, assim como o ponto de fusão, com valor médio de 72,9 ºC ± 1,7 ºC durante todo o período de avaliação do teste de estabilidade (90 dias).

ABSTRACT

The purpose of this study was to measure and investigate the acute effects of two fatty meals (high-SFA & high-PUFA) on post-prandial thermic effect, substrate oxidation, and satiety. Eight healthy adults (four males and four females) aged 19-22 years were assigned to consume two isocaloric meals: high in saturated fatty acids from butter and high in polyunsaturated fatty acids from sesame oil. Indirect calorimetry was used to measure resting energy expenditure (REE), post-prandial energy expenditure for five hours, and substrate oxidation. Satiety of the subjects after meals was estimated by using visual analogue scales (VAS). Five hours thermic effect of food (TEF) was not significantly different between butter meal (6.5% of energy intake) and sesame oil meal (7.3% of energy intake), but, the TEF of butter meal reached the peak point at 150 min and decreased more rapidly arriving to REE in 270 min. On the other hand, TEF of sesame oil meal reached the peak at 90 min and decreased slower than butter meal (still higher than REE at 300 min). No significant differences in substrate oxidation rates were found between the two meals. Post-prandial fat oxidation rates increased significantly after the consumption of both butter and sesame oil meal than that of the pre-prandial state. Satiety values (hunger, fullness, and appetite) were similar among the meals, but recovery of hunger and fullness to the pre-prandial state was faster in butter meal than that of the sesame oil meal.

ABSTRACT

Margarines are industrial products obtained mainly from the soft hydrogenation of vegetable and marine oils. Originally developed as substitutes of butter, margarines are presently highly demanded and consumed because today industrial procedures allow the manufacture of products, which resemble butter, being however, less expensive and more stable than milk fat. Ten years ago (1999) we analyzed the composition of the different spread margarines expended in Chile in relation to its fat origin and content, fatty acid composition, trans isomers, cholesterol and vitamin content. Ai this time four types of margarines were expended: manufactured from vegetable fat; from animal fat (hydrogenated fish oil); vegetable fat and VTF (virtually trans free); and vegetable fat dietetic and VTF. To day, the scenario is substantially different. Twenty-eight, different spread margarines are commercialized in Chile, corresponding to a wide variety of products having different amount and composition of fat and additives. Although the classification of each margarine is difficult due the variety of hem, we intended to separate the different products in five categories: "Traditional", those having 80 percent fat or less with no other additives different than those regulated; "Light": those products that contain less than 80 percent fat and added of additives different than those regulated; "With milk": added of skimmed milk; "With butter", and ; "With functionality": margarines added of omega-3 fatty acids, fiber, or phytosterols. Because the wide variety of margarine expended in Chile, it is difficult to decide which product may be better than butter. However, as a generally rule, those margarine manufactured exclusively from vegetable oils, containing no cholesterol and trans fatty acids, with a high content of omega-6 and omega-3 fatty acids, and eventually with less than 80 percent fat, may be considered a product nutritionally more recommendable than butter.


Las margarinas son productos industriales obtenidos a partir de la hidrogenación de aceites vegetales y marinos. Originalmente se desarrollaron como sustitutos de la mantequilla. Actualmente son productos de alta demanda y consumo debido a que los procedimientos industriales actuales permiten la obtención de productos muy similares a la mantequilla, de menor costo y más estables que la grasa láctea. Hace diez años atrás (1999) nuestro grupo realizó un análisis de la composición de ácidos grasos, de isómeros trans, de colesterol y del contenido de vitaminas de las diferentes margarinas de mesa en potes que se comercializaban en Chile. En aquella época solo había disponible cuatro tipos de margarinas: manufacturadas con grasa hidrogenada de origen vegetal; con grasa hidrogenada de origen animal (aceite de pescado hidrogenado), con grasa vegetal tipo VTF (virtually trans free), y con grasa vegetal VTF dietética. Actualmente, el escenario es sustancialmente diferente. En Chile se comercializan veintiocho tipos diferentes de margarinas de mesa en potes y que corresponden a una amplia variedad que incluye diferente composición de grasa y de aditivos. Aunque la clasificación es difícil debido a la gran variedad, hemos separado los diferentes productos en cinco categorías: "Tradicionales", aquellas margarinas con un 80 por ciento de grasa, o menos, pero que no son adicionadas de ningún aditivo salvo los regulados; "Light", aquellas que contienen menos de 80 por ciento de grasa, adicionadas de aditivos diferentes a los regulados; "Con leche", productos adicionados de leche descremada; "Con mantequilla", y; "Con funcionalidad", esto es margarinas adicionadas de ácidos grasos omega-3, fibra, o fitoesteroles. Debido a la gran variedad de margarinas que se comercializan en Chile, es difícil decidir qué producto es mejor que la mantequilla. Sin embargo, como regla general, aquellas margarinas manufacturadas exclusivamente con aceites vegetales, que no contienen colesterol...

ABSTRACT

A história econômica de Salinas apóia-se em grande parte na pecuária. Os desbravadores encontraram na região do município, um grande potencial para o desenvolvimento de suas atividades, seja na lavoura de mantimentos, seja na pecuária (OLIVEIRA, 2000). Até hoje, a produção de leite ocupa certo destaque nas atividades da agricultura familiar que, além do leite "in natura", fornece também o queijo de coalho, o requeijão e, dos soros obtidos desses produtos elabora-se a manteiga de garrafa. Assim, esse estudo foi realizado com o objetivo de analisar o perfil dos ácidos graxos de manteigas de garrafa produzidas em Salinas, norte de Minas Gerais e análise da relação de ácidos graxos saturados: ácidos graxos insaturados dessas manteigas. O perfil dos ácidos graxos das manteigas de garrafa foi determinado por análises cromatográficas, realizadas segundo a metodologia desenvolvida por Luddy et al. (1960), modificada por Abreu (1993). Foi realizada análise de variância, comparando-se as médias pelo teste de Tukey em nível de 5 por cento de probabilidade. O perfil dos ácidos graxos de todas as manteigas de garrafa analisadas apresentou-se semelhante. Não foram detectados os picos para os ácidos butírico (C4) e capróico (C6). O teor de ácidos graxos saturados apresentou-se mais elevado do que o de ácidos graxos insaturados, com médias de 60,36 por cento e 39,64 por cento, respectivamente.


The economic history of Salinas, Minas Gerais is largely based on cattle-breeding. The discoverers found in the city's region a large potential for the progress of their activities, either in agriculture or in cattle-breeding (OLIVEIRA, 2000). Even today, milk production plays an important role in family farming activities, which besides raw milk, provides curdal cheese, cottage cheese, and "bottled butter fat", which is manufactured with fat extracted from whey. Therefore, this study was conducted to analyze the fatty acid profile of "bottled butter fat" produced in Salinas, in the northern region of Minas Gerais , and also to analyze the ratio of saturated to unsaturated fatty acid of these butters. The fatty acid profile of the "bottled butter fat" was determined by chromatographic analysis, according to methodology advanced by Luddy et al. (1960), and later modified by Abreu (1993). Analysis of variance was applied for comparison of the averages by the Tukey test at 5 percent probability. The fatty acid profiles of all the "bottled butter fat" were found to be similar. The concentration of saturated fatty acids was higher than that of the unsaturated, with averages of 60,36 percent and 39,64 percent, respectively.
