ABSTRACT

Abstract Among several fruits, mangaba (Hancornia speciosa Gomes), it aroused the interest of producers and consumers due to its attractive sensory characteristics and health beneficial properties (high nutritional value and presence of bioactive substances), thus, this work evaluates the nutritional factors of the flour residue of mangaba processing that is despised by the food industry, and the influence of temperature on its production. The mangaba processing residue was splited in two main groups: in natura sample (control), and other for preparation of flour that was dried at 50 °C and divided into two other groups: treatment A (flour with roasts at 110 °C and 130 °C) and treatment B (flour from drying at 50 °C). The nutritional characteristics of flours were analyzed considering the chemical parameters: pH, titratable total acidity and soluble solids, in addition to the determination of moisture content, total lipids, total dietary fiber and ash, total energy value, antioxidant activity, phytochemical screening, quantification of phenolic compounds and flavonoids, as well as technological functional properties (water absorption index (WAI), water solubility index (WSI), milk absorption index (MAI) and milk solubility index (MSI) and oil absorption index (OAI). The results showed that the bioactive compounds present in the extracts do not have significant properties of acting as free radical kidnappers. The heat treatment, performed in the flour of mangaba processing residues, influenced the nutritional factors and properties of absorption and solubility, which showed statistical differences. These results show that the flour is a viable alternative for the energy enrichment of diets, contributing to the development of new products, the reduction of the disposal of these residues and consequently to the minimization of the environmental impact.


Resumo Dentre as diversas frutas a mangaba (Hancornia speciosa Gomes), despertou interesse de produtores e consumidores devido às suas características sensoriais atrativas e propriedades benéficas à saúde (elevado valor nutricional e presença de substâncias bioativas), assim, o trabalho avaliar os fatores nutricionais do resíduo da farinha de processamento de mangaba que é desprezado pela indústria alimentícia e, a influência da temperatura na sua produção. O resíduo de processamento da mangaba foi dividido em dois lotes, sendo um deles utilizado para as análises in natura (amostra controle) e o outro para a confecção da farinha que foi seca a 50 °C, e dividida em dois lotes: tratamento A (farinha com torras a 110 °C e 130 °C) e no tratamento B (farinha oriunda da secagem a 50 °C). Analisou-se as características nutricionais de farinhas considerando os parâmetros químicos: pH, acidez total titulável e sólidos solúveis, além da determinação do teor de umidade, lipídios totais, fibra alimentar total e cinzas, valor energético total, atividade antioxidante, triagem fitoquímica, quantificação de compostos fenólicos e flavonoides, bem como as propriedades funcionais tecnológicas (índice de absorção de água (IAA), índice de solubilidade em água (ISA), índice de absorção de leite (IAL) e índice de solubilidade em leite (ISL) e índice de absorção de óleo (IAO). Na análise foi inferido que os compostos bioativos presentes nos extratos não possuem propriedades significativas de agir como sequestradores de radicais livres. O tratamento térmico, realizado na farinha de resíduos de processamento de mangaba, influenciou nos dados dos fatores nutricionais e das propriedades de absorção e solubilidade, os quais apresentaram diferenças estatísticas. Estes resultados credenciam a farinha como uma alternativa viável para o enriquecimento energético de dietas, contribuindo para o desenvolvimento de novos produtos, a redução do descarte desses resíduos e consequentemente para a minimização do impacto ambiental.

ABSTRACT

El basul es el fruto de la planta Erythrina edulis que posee un alto contenido de proteínas, fibra dietética y antioxidantes, pero también con contenido de antinutrientes. Objetivo. El objetivo del estudio fue evaluar el efecto del germinado sobre las características nutricionales, propiedades bioactivas y funcionales de las semillas de basul. Materiales y métodos. Mediante un diseño aleatorizado con arreglo factorial de 2x2x2 (tiempo de remojo, tiempo de germinado, presencia o ausencia de luz), las semillas de basul fueron germinadas y convertidas en harina (HBG) para determinar la composición proximal y la digestibilidad in vitro de la proteína. Además, se ha determinado los fenoles totales (CFT), la capacidad antioxidante (métodos ABTS y DPPH) y las propiedades de hidratación y adsorción de aceite. Resultados. Las diferentes condiciones de germinado no han modificado la composición proximal de la HBG; sin embargo, la digestibilidad in vitro de la proteína incrementó hasta en 6,25% en uno de los tratamientos respecto a la muestra no germinada. El CFT, también ha incrementado de 241,49 mg AGE/100g (sin germinar) a 267,15 mg AGE/100g (germinado); al igual que la capacidad antioxidante (ABTS) de 173,04 µmolTE/g (sin germinar) a 195,67 µmolTE/g (germinado). También se tuvo incrementos en la solubilidad, la capacidad de absorción de agua y la capacidad de hinchamiento. Conclusión. La calidad de la proteína, el contenido de fenoles totales, la capacidad antioxidante y propiedades funcionales de interacción con el agua de la semilla de basul mejora con el germinado(AU)


Basul is the fruit of the Erythrina edulis plant. It has a high content of proteins, dietary fiber, and antioxidants, but it also contains antinutrients. Objective. The study objective was to evaluate the effect of sprouting on the nutritional characteristics, bioactive and functional properties of basul seeds. Materials and methods. Basul seeds were germinated to produce flour (HBG) and determine its proximal composition and in vitro digestibility of the protein through a randomized design with a 2x2x2 factorial arrangement (soaking time, germination time, and presence or absence of light). Total phenols (CFT), antioxidant capacity (ABTS and DPPH methods), and hydration and oil adsorption properties were also determined. Results. The different germination conditions did not modify the proximal composition of HBG. However, the in vitro digestibility of the protein increased up to 6.25% in one of the treatments compared to the non-germinated sample. The CFT also increased from 241.49 mg AGE/100g (without germination) to 267.15 mg AGE/100g (germinated) and the antioxidant capacity (ABTS) from 173.04 µmolTE/g (without germination) to 195.67 µmolTE/g (germinated). Solubility, water absorption capacity, and swelling capacity also increased. Conclusion. The quality of the protein, the content of total phenols, the antioxidant capacity, and the functional properties of interaction with the water of the basul seed improved with germination(AU)

ABSTRACT

Abstract Six different bread wheat genotypes; two Egyptian commercial varieties (control); Giza-168 and Gemmeiza-11, and four promising lines; L84 and L148, resulted via hybridization and M10 and M34 via radiation mutation program) were rheologically evaluated using extensograph and for protein, analysis using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The radiation mutant M10 and M34 had the highest maximum resistance which is a very good indicator of strong gluten. The amount of gluten content was higher in M10, L148, and M34 compared to the control samples Gz168 and Gm11. Sulfide amino acids (CYS and MET) are slightly higher in M10. The electrophoretic results and amino acid analyzers show that the best technological quality was exhibited by M10. Radiation mutants wheat genotypes have a protein with good characteristics, mainly gluten which is significantly higher compared to control samples. The rheological properties measured as extensograph and gel electrophoresis were much better in irradiated lines M10 and M34.


Resumo Seis diferentes genótipos de trigo de pão, duas variedades comerciais egípcias (controle) - Giza-168 e Gemmeiza-11 - e quatro linhas promissoras - L84 e L148, obtidas via hibridação, e M10 e M34, via programa de mutação por radiação - foram avaliados reologicamente por meio de extensógrafo, enquanto, para proteínas, foram feitas análises utilizando eletroforese em gel de poliacrilamida com dodecilsulfato de sódio (SDS-PAGE). Os mutantes de radiação M10 e M34 apresentaram a maior resistência máxima, o que é um indicador muito bom de glúten forte. A quantidade de glúten foi maior em M10, L148 e M34 em comparação com as amostras de controle Gz168 e Gm11. Os aminoácidos sulfurados (CYS e MET) são um pouco mais altos no M10. Os resultados eletroforéticos e analisadores de aminoácidos mostram que a melhor qualidade tecnológica foi exibida pelo M10. Os genótipos de trigo mutantes da radiação possuem uma proteína com boas características, principalmente o glúten, que é significativamente maior em comparação às amostras do grupo controle. As propriedades reológicas medidas, como extensógrafo e eletroforese em gel, foram muito melhores nas linhas irradiadas M10 e M34.

ABSTRACT

Introdução:O Brasil está no ranking dos 10 países que mais desperdiçam alimentos no mundo, é também o 3º maior produtor de frutas. As cascas e sementes, que são desprezadas, podem ser utilizadas na alimentação por meio do aproveitamento integral de alimentos. Objetivo:Verificar características organolépticas de preparações culinárias elaboradas com farinha das sementes de melão cantaloupe (Cucumis melo L. var. reticulatus). Metodologia:O trabalho trata-se de um estudo piloto, em que foi elaborada farinha de sementes do melão utilizada na produção de dois coprodutos, bolo simples e torta de frango, elaborados com diferentes percentuais de farinha das sementes, sendo de 25%, 50% e 75% adicionada à farinha de trigo enriquecida com ferro e ácido fólico. Posteriormente foi realizada degustação das amostras para realização da avaliação das características organolépticas dos coprodutos elaborados. Resultados:As preparações feitas com farinha cuja constituição possuía 50% de farinha de sementes foram as comentadas na avaliação das características organolépticas, visto que eram mais palatáveis, em virtude da menor quantidade de resíduos, bem como apresentaram aroma e sabor mais agradáveis quando comparadas às amostras de 75% de farinha de sementes. Conclusões:Diante dos resultados observou-se que os participantes optaram pelos produtos que possuíam quantidade intermediária de resíduos de melão nas preparações, sendo os produtos cuja concentração era 50% de farinha de sementes, visto que não dificultavam a mastigação e deglutição, bem como não tiveram alterações significativas nas características organolépticas como aroma e sabor. Espera-se que em breve com a volta das atividades presenciais, a análise sensorial com provadores não treinados seja realizada para continuidade e conclusão do estudo (AU).


Introduction:Brazil is in the ranking of the 10 countries that most waste food in the world, it is also the 3rd largest fruit producer. The husks and seeds that are neglected can be used in food through the full use of food. Objective:To verify organoleptic characteristics of culinary preparations made with flour from cantaloupe melon seeds (Cucumis melo L. var. Reticulatus).Methodology:The work is a pilot study in which cantaloupe melon melon seed meal flour was used to produce two co-products, simple cake and chicken pie, made with different percentages of flour of the seeds, 25%, 50% and 75% being added to wheat flour enriched with iron and folic acid. Subsequently, samples were tasted to evaluate the organoleptic characteristics of the elaborated by-products.Results:The preparations made with flour whose constitution had 50% of seed meal were those mentioned in the evaluation of the organoleptic characteristics, since they were more palatable, due to the lower amount of residues, as well as presenting a more pleasant aroma and flavor when compared to 75% samples. of seed meal. Conclusions:In view of the results, it was observed that the participants opted for products that had an intermediate amount of melon residues in the preparations, being the products whose concentration was 50% ofseed meal, since they did not hinder chewing and swallowing, as well as had no significant changes in organoleptic characteristics such as aroma and flavor. It is expected that soon with the return of face-to-face activities, sensory analysis with untrained tasters will be carried out for the continuity and conclude of the study (AU).

ABSTRACT

The objective of this work was to develop cookies using sorghum, germinated millet and chia flours. Four formulations (F) were used: F-sorghum (100% sorghum flour); F-Sorghum + chia (50% sorghum flour and 50% chia flour), F-millet (100% millet flour) and F-millet + chia (50% millet flour and 50% chia flour). The germinated millet flour was submitted to microbiological analysis. All cookies were evaluated in relation to chemical and sensory analyses, according to AOAC and hedonic nine-point scale, respectively. The statistical analysis was performed by the variance analysis and Tukey test at 5% probability. The F-millet formulation showed the least humidity content (4.59 ± 0.25g/100g), while chia containing cookies showed lesser concentrations of carbohydrates (F-sorghum + chia: 44.35 ± 4.34g/100g and F-millet + chia: 41.03 ± 1.40g/100g) and higher ash content (F-sorghum + chia: 3.80 ± 0.02g/100g and F-millet + chia: 3.42 ± 0.24g/100g) and of protein (F-sorghum + chia: 15.38 ± 0.44 g/100g and F-millet + chia: 18.06 ± 0.53 g/100g). The caloric value and the lipids content did not differ among formulations. The sensory analysis had 57 evaluators. The cookies produced with chia and germinated millet had higher rates for flavor, texture and general impression. In general, all tested biscuits had good sensory acceptance and nutritional quality being an alternative to increase the consumption of bioactive compounds and antioxidants(AU)

ABSTRACT

Introducción. El enriquecimiento de la harina de trigo es una de las estrategias de salud pública recomendadas para prevenir las deficiencias de micronutrientes, entre ellos el hierro. El objetivo de este trabajo fue determinar el contenido de hierro en harina de trigo enriquecida y sus derivados, y la contribución de estos a las recomendaciones nutricionales en niños. Población y métodos. Estudio observacional, analítico, de corte transversal, basado en la metodología de estudio de dieta total. Se analizaron la harina de trigo enriquecida (según la ley 25630) y sus derivados más consumidos. Para seleccionar los alimentos, se realizó un cuestionario de frecuencia de consumo y recordatorio de 24 horas a los padres de niños con edades entre 6 meses y 7 años. Se determinó la concentración de hierro en los alimentos mediante absorción atómica y se evaluó su contribución al requerimiento promedio estimado. Resultados. La harina enriquecida y sus derivados tuvieron la cantidad de hierro esperada, excepto el pan francés y el pan rallado. La contribución a los requerimientos de hierro de los alimentos evaluados fue el 7 % en niños de 6 meses a 1 año, el 81 % en el grupo de 1 a 3 años y el 45 % en los mayores de 4 años. Conclusiones. Excepto el pan francés y el pan rallado, las harinas y sus derivados analizados presentaron el nivel de enriquecimiento esperado. El consumo de estos alimentos no aporta cantidades significativas de hierro en los lactantes, pero sí en los niños mayores de 1 año.


Introduction. Wheat flour enrichment is a public health strategy recommended to prevent micronutrient deficiencies, including iron deficiency. The objective of this study was to determine iron content in enriched wheat flour and flour products and their contribution to nutritional recommendations for children. Population and methods. Observational, analytical, cross-sectional study based on the total diet study method. Enriched wheat flour (as per Law no. 25630) and the most frequently consumed flour products were analyzed. Products were selected using a questionnaire on the frequency of food intake and a 24-hour recall interview with the parents of children aged 6 months to 7 years. Food iron levels were determined based on atomic absorption spectrometry and their contribution to the estimated average requirement was assessed. Results. Enriched flour and flour products showed the expected iron amount, except for French bread and breadcrumbs. The contribution of studied products to iron requirements was 7 % in children aged 6 months to 1 year, 81 % in those aged 1-3 years, and 45 % in those older than 4 years. Conclusions. Except for French bread and breadcrumbs, studied flour and flour products showed the expected enrichment level. The consumption of this type of food does not provide significant amounts of iron to infants, but it does to children older than 1 year.

ABSTRACT

BACKGROUND@#International Labour Organization (ILO) report indicates more than 2.4 million workers die from work-related diseases and accidents each year. Work-related respiratory ailments related to airborne particulate matter such as flour dust are responsible for about 386,000 deaths and 6.6 million illness-adjusted life years. Even though exposure to flour dust together with the extreme expansions of flour mill sectors is a priority health concern, extent of the problem is little investigated in Ethiopia. The aim of this study was to evaluate the magnitude and risk factors of work-related respiratory symptoms among flour mill workers in Bahir Dar City, Ethiopia.@*METHODS@#This study employed a comparative cross-sectional survey of 560 samples (280 exposed group from flour mill workers and 280 unexposed group from office workers) with a stratified random sampling technique. The study was conducted from March to April 2019 in Bahir Dar City, Northwest Ethiopia. We used the British Medical Research Council (BMRC) questionnaire to assess work-related respiratory symptoms. The questionnaire was pretested and interview administered to collect data. Binary logistic regression analysis was fitted to evaluate significant factors of respiratory symptoms at a < 0.05 p value. Adjusted odds ratio (AOR) with a confidence interval (CI) of 95% was calculated to determine a strength of association.@*RESULTS@#All the sampled participants had fully responded to the interview. The median age of exposed and unexposed groups was 28.5 interquartile range (IQR, 20) and 31 (IQR, 15) years, respectively. The prevalence of work-related respiratory symptoms among flour mill workers was substantially higher than that of among controls, 63.9% and 20.7%, respectively (Χ@*CONCLUSION@#Respiratory symptoms emanating from exposure to various flour dusts were significantly higher among flour mill workers than among the control group. Therefore, we recommend the need to effectively implement health and safety programs that account for the reduction of dust at a source, use of engineering controls (e.g., provision of adequate ventilation systems), use of administrative measures (e.g., training program and health surveillance) and provision of a suitable personal protective equipment (PPE). Furthermore, it is vital to integrate workplace health and safety programs to the wider public health policies and strategies to effectively mitigate the burden of work-related respiratory conditions. We also encourage future studies to evaluate concentration of flour dusts combined with physical examinations to establish plausible associations of respiratory symptoms with dusts of flour mill-related origin.

ABSTRACT

The objective of this study was to determine the metabolizable energy, standardized ileal amino acid digestibility (SIAAD) and digestible amino acid values of wheat meal (WM), wheat gluten meal (WGM), meat bone meal (MBM) and poultry-by-product meal (PPM) in diets for broilers. In the first experiment, the total excreta collection method was used, with 180 chicks with 14 days, distributed in a completely randomized design, with 4 feeds + reference diet with 6 replicates and 6 broilers each. In the second experiment, 180 broilers from 24 to 28 days old were used, distributed in a completely randomized design, with 4 feeds + one protein free diet with 6 replicates and 6 broilers each. The AMEn values of WM, WGM, MBM and PPM were 3052, 3174, 1556 and 3200 (kcal/kg), respectively. The average SIAAD of the essential and non-essential amino acids of WM, WGM, MBM and PPM were 74.21, 97.50, 69.28 and 83.08; 76.32, 96.42, 63.93 and 77.66, respectively. The values of the main digestible limiting amino acids were 0.18, 1.42, 0.41 and 0.94 for methionine; 0.20, 1.48, 1.73 and 2.73 for lysine; 0.23, 1.67, 0.72 and 1.89 for threonine; and 0.35, 3.22, 1.38 and 2.47 for valine, respectively for the feedstuffs in study.(AU)

ABSTRACT

Abstract Fitness in parasitoids is generally influenced by host quality. We evaluated the development parameters of Doryctobracon areolatus (Hymenoptera: Braconidae) parasitoid on Anastrepha fraterculus (Diptera: Tephritidae) larvae, reared in artificial diets with different protein sources. Larvae of A. fraterculus were reared in the diets based on 1) raw wheat germ (control); 2) whole rice flour; 3) corn flour; and, 4) whole wheat flour + soybean meal. The larvae were used for the development of D. areolatus, to evaluate the number of offspring/female, emergence rate, sex ratio, egg-adult period, adult weight posterior tibia length and longevity. Larvae of A. fraterculus reared in the diets based on wheat germ and corn flour obtained a greater number of offspring, with shorter duration of egg-adult period for males and females. In diets with rice flour and corn flour, A. fraterculus larvae generated adults of D. areolatus with greater weight, longer tibia length and higher sex ratio, whereas larvae reared in wheat flour + soybean meal diet had a lower sex ratio. The diets based on rice flour and corn are the most appropriate for multiplication of the parasitoid.


Resumo O custo adaptativo de parasitoides é geralmente influenciado pela qualidade do hospedeiro. Nós avaliamos parâmetros de desenvolvimento do parasitoide Doryctobracon areolatus (Hymenoptera: Braconidae) em larvas de Anastrepha fraterculus (Diptera: Tephritidae) criadas em dieta artificial com diferentes fontes proteicas. Larvas de A. fraterculus foram criadas em dietas a base de: 1) germe de trigo cru (testemunha); 2) farinha de arroz integral; 3) farinha de milho; e, 4) farinha de trigo integral + farelo de soja. As larvas foram usadas para o desenvolvimento de D. areolatus para avaliar o número de descendentes/fêmea, taxa de emergência, razão sexual, duração do período ovo-adulto, peso de adultos, comprimento da tíbia posterior e longevidade. Larvas de A. fraterculus criadas nas dietas a base de germe de trigo e farinha de milho, permitiram obter um maior número de descendentes do parasitoide, com menor duração do período de desenvolvimento ovo-adulto, para ambos os sexos. Nas dietas com farinha de arroz e farinha de milho, larvas de A. fraterculus geraram adultos de D. areolatus com maior peso e tamanho de tíbia de machos e fêmeas e uma maior quantidade de fêmeas. A dieta contendo farinha de trigo + farelo de soja afetou a geração de descendentes, causando uma menor razão sexual. As dietas a base de farinha de arroz e milho são as mais adequadas para a multiplicação do parasitoide.

ABSTRACT

ABSTRACT Objectives Yacon flour is rich in bioactive compounds (phenolic compounds and fructooligosaccharides (FOS)), and may therefore reduce the risk of diseases associated with excess body weight. However, its effect on fecal short chain fatty acids (SCFA), intestinal permeability, oxidative stress and inflammation markers has not been studied in adult humans with excess body weight. Thus, we evaluated the effect of the consumption of yacon flour on these variables. Materials and methods Twenty-six excess body weight (30.4 ± 2.4 kg/m2) adults (31.3 ± 8.5y) were randomized to one of two groups (yacon flour or control; n = 13) on a double blind clinical trial. Subjects received a breakfast drink containing or not yacon flour (25g) associated with an energy restricted diet, for six weeks. The flour chemical characterization, FOS and total phenolics contents were evaluated. Antioxidant capacity was evaluated in vitro and in vivo (plasma). Intestinal permeability, fecal SCFA, oxidative stress and inflammatory markers also were evaluated in vivo. Results Yacon flour was well tolerated. It presented an in vitro and in vivo antioxidant capacity, increased plasma total antioxidant capacity (ΔYAC: 49.16 (-4.20; 156.63)) and reduced protein carbonyl concentrations (ΔYAC: -0.98 (-1.54; -0.42)). A reduction in SCFAs was observed in both groups (Δacetic: -3.16 (-5.07; -0.95) vs. -1.05 (-2.65; 1.11); Δpropionic: -1.05 (-2.60;-0.38) vs. -0.41 (-2.08; 0.09); Δbutyric: -0.75 (-1.38; -0.04) vs. -0.28 (-0.98; 0.11), for YAC and CON, respectively). Other variables did not change. Conclusion The yacon flour increased the plasma antioxidant capacity, decreased oxidative stress and SCFAs in adults with obesity or overweight.

ABSTRACT

Introducción: los productos de panificación utilizan harina de trigo la cual contiene gluten. Algunas personas son intolerantes específicamente a las proteínas del gluten que generan enfer-medades como colon irritable y problemas gastrointestinales.El chachafruto es el fruto del árbol llamado Erythrina edulis, planta catalogada como leguminosa y su fruto como legumbre. Esta le-gumbre se considera un alimento esencial ya que posee nutrientes y proteínas, y es una opción de alimentación porque no contiene gluten. Su contenido de grasa es bajo y de proteínas alto. Objetivos: evaluar la utilización de la harina de chachafruto en la elaboración de un producto libre de gluten. Materiales y métodos: la harina de chachafruto se consigue al separar las semillas de la vaina, luego se lavan y desinfectan para eliminar impurezas y se llevan a escaldado con agua caliente du-rante 5 minutos. Posteriormente se realiza el pelado mecánico y se remueve la testa manualmente; después se cortan las semillas en forma de rodaja en la cortadora con un espesor de 3 mm y se pasan a un deshidratador de bandejas. El secado se lleva acabo a temperaturas de 50 y 60°C aproximadamente por 12 horas. Resultados: la adición de harina de chachafruto cambió consi-derablemente algunos parámetros de las mezclas para 15% ha-rina de chachafruto y 85% harina de amaranto en las proteínas con 8,00±2,52% y cenizas con 1,80±0,02%, y para la mezcla de 15% harina de chachafruto y 85% harina de arroz cambió 7,38±2,16% y 1,39±0,00% respectivamente. Conclusiones: este estudio demostró que el empleo de harina de chachafruto puede utilizarse efectivamente como reempla-zante de la harina de trigo dado que los resultados obtenidos favorecen la fabricación de productos para reemplazar total-mente la harina de trigo por harinas sin gluten.

ABSTRACT

RESUMEN Con la finalidad de diversificar el uso de las harinas de plátano pelipita (Musa ABB) y batata (Ipomoea batatas), se propuso evaluar la funcionalidad de una galleta sustituyendo la harina de trigo con 70% de harina de plátano pelipita y 30% harina de batata con el fin de obtener un producto con propiedades físicas y organolépticas agradables, además de mejorar la calidad nutricional, en cuanto a fibra dietaría y almidones resistentes. Las galletas elaboradas a base de harina de plátano pelipita y batata incrementaron significativamente, con respecto a la galleta patrón (GP), en los siguientes componentes químicos: ceniza (0,6 a 2,1%), proteínas (de 3,9 a 5,3%), fibra dietaría (4,1 a 5,3%) y azucares totales (24,1 a 22,1%). La galleta de harina de plátano y batata cumple con los requerimientos establecidos en la industria en cuanto a humedad (3,3%), aw (0,410) y color (L= 49,3 a= 4,79 y b= 19,3). Los resultados mostraron que la harina compuesta, contribuyó a un ligero incremento en las fracciones de fibra, proteínas, ceniza, fósforo, calcio y hierro en las galletas. En conclusión, el uso de la harina de batata y plátano en una relación de 30% - 70% respectivamente, resultó un ingrediente adecuado en la elaboración de galletas con alta preferencia sensorial, constituyendo una alternativa como fuente de fibra dietética.


ABSTRACT In order to diversify the use of Pelipita banana (Musa ABB) and sweet potato (Ipomoea batatas) flours, we proposed evaluating the functionality of a cookie replacing wheat flour with 70% Pelipita banana flour and 30% sweet potato flour in order to obtain a product with pleasant organoleptic and physical properties and improved nutritional quality, in terms of dietary fiber and resistant starch. Cookies prepared from Pelipita banana and sweet potato flours increased significantly with respect to the following chemical components: ash (from 0.6 to 2.1%), protein (3.9 to 5.3%), dietary fiber (4.1 to 5.3%) and total sugars (24.1 to 22.1%). Cookies made with banana and sweet potato flour met the requirements established in the industry in terms of moisture (3.3%), aw (0.410) and color (L= 49.3 a= 4.79 and b= 19.3). The results showed that the composite flour, contributed to a slight increase in fractions of fiber, protein, ash, phosphorus, calcium and iron in cookies. In conclusion, the use of sweet potato and banana flours in a ratio of 30%-70% respectively, was a suitable ingredient in the production of biscuits with high sensory preference, constituting an alternative source of dietary fiber.

ABSTRACT

Jatobá (Hymenaea sp.) is an arboreal legume native to the Brazilian Savannah (Cerrado) and its fruit has a high functional potential, but the jatobá-da-mata specie has been poorly explored. This study evaluated the nutritional profile, bioactive compounds and antioxidant capacity of jatobá-da-mata byproducts: pulp flour, fibrous pulp residue and sap. Jatobá fruits were pulped to obtain pulp flour and fibrous pulp residue, and the jatobá tree's sap was obtained in a typical extraction location in the Cerrado (Brazilian Savannah). Fibrous pulp residue and pulp flour had high protein (11 and 12 g/100 g) and dietary fiber (49 and 44 g/100 g) content, respectively, and the fibrous residue showed the highest total and insoluble fibers, ash and vitamin C content. Regarding polyphenols, the fibrous residue showed a high concentration (775 mg GAE/100 g); an intermediate value in pulp flour (462 mg GAE/100 g); and considerable content in sap(181 mg GAE/100 g). Jatobá residue and pulp flour are suitable ingredients for the formulation of functional foods, and the sap is a promising non-caloric product with potential health benefits.


Jatobá (Hymenaea sp.) es una leguminosa arbórea originaria de la sabana brasileña y su fruto tiene un alto potencial funcional, pero la especie jatobá-da-mata ha sido poco explorada. El objetivo del estudio fue evaluar el perfil nutricional, compuestos bioactivos y capacidad antioxidante de subproductos del jatobá-da-mata: harina de la pulpa, residuo fibroso de la pulpa y la savia. Los frutos fueron despulpados para obtener la harina juntamente con el residuo fibroso de la pulpa, y la savia de la planta fue obtenida en un lugar exclusivo de extracción en el Cerrado (Sábana brasileña). El residuo fibroso y la harina de la pulpa contienen un alto contenido de proteína (11 y 12 g/100 g) y de fibra dietética (49 y 44 g/100 g), respectivamente, y el residuo fibroso mostró el mayor contenido de fibras totales y insolubles, cenizas y vitamina C. En cuanto a los polifenoles, el residuo fibroso presentó alta concentración (775 mg AGE/100 g); la harina de la pulpa, un valor intermedio (462 mg AGE/100 g); y la savia, un contenido considerable (181 mg AGE/100 g). El residuo fibroso y la harina de la pulpa son ingredientes adecuados en la formulación de alimentos funcionales, y la savia es un producto no calórico prometedor con potenciales beneficios a la salud.

ABSTRACT

Introducción. La fortificación y suplementación son estrategias para la prevención de carencias de micronutrientes. El objetivo fue describir la procedencia de la ingesta del hierro y ácido fólico a lo largo del ciclo vital de la población de la Ciudad Autónoma de Buenos Aires. Población y métodos. Análisis de la información de la Primera Encuesta Alimentaria y Nutricional de la Ciudad Autónoma de Buenos Aires 2011, que tomó una muestra probabilística por conglomerados. El consumo se recabó con recordatorio de 24 horas. Se calculó el aporte de hierro y ácido fólico, y se categorizó en contenido natural, harina de trigo enriquecida, leche del Plan Materno Infantil, alimentos fortificados y suplementos. Resultados. De los 5369 individuos evaluados, prácticamente, la totalidad obtenía hierro y ácido fólico de contenido natural (el 58 % y el 29 % del consumo, respectivamente). Más del 90 % consumía harina de trigo enriquecida, que aportaba el 28 % del hierro y el 54 % del ácido fólico. Los alimentos fortificados mostraron consumo y aporte muy variable. La leche del Plan Materno Infantil mostró muy baja participación, inclusive en grupos específicos. El aporte de suplementos fue bajo, excepto en < 2 años (el 30 % consumía suplementos de hierro, que aportaban el 38 % de este).Conclusión. Además del aporte natural de los alimentos, la harina de trigo enriquecida representó una importante contribución en el consumo de ácido fólico y hierro de esta población; los alimentos fortificados y los suplementos tuvieron una participación diferente según el grupo etario.


Introduction. Fortification and supplementation are two strategies for micronutrient deficiency prevention. The objective of this study was to describe the source of iron and folic acid intake throughout the life cycle in the population of the Autonomous City of Buenos Aires.Population and methods. Analysis of the information collected in the First Survey on Nutritional Food Intake of the Autonomous City of Buenos Aires (2011), which had a probability cluster sampling design. Consumption was assessed by means of a 24-hour recall. Iron and folic acid intake was estimated and categorized into natural content, enriched wheat flour, milk from the Maternal and Child Plan, fortified foods, and supplements.Results. Out of the 5369 studied individuals, practically all got iron and folic acid from natural contents (58 % and 29 % of intake, respectively). More than 90 % consumed enriched wheat flour, which provided 28 % of iron and 54 % of folic acid. Fortified food consumption and intake varied greatly. Milk intake from the Maternal and Child Plan was small, even in specific groups. Intake from supplements was low, except in children < 2 years old (30 % consumed iron supplements, which accounted for 38 % of iron).Conclusion. In addition to natural intake from foods, enriched wheat flour accounted for a major source of folic acid and iron in this population; intake from fortified foods and supplements varied by age group.

ABSTRACT

INTRODUCCIÓN: el bromato de potasio es una sustancia mejoradora del pan que actualmente está prohibida para su uso en la elaboración del pan porque se considera nociva para el ser humano, produciendo principalmente daños gastrointestinales. Es así que los organismos de control de alimentos prohíben su uso completamente, al igual que la NB 39007:2012 harina y derivados-productos panificados-requisitos en su tercera revisión, en nuestro país. OBJETIVO: determinar la presencia del bromato de potasio en panes expedidos en supermercados de la ciudad de La Paz. MÉTODOS: el método cualitativo para Bromatos /Yodatos y el método indirecto con el reactivo fucsina bisulfito fueron los métodos oficiales aplicados para la determinación de bromato de potasio. RESULTADOS: el porcentaje de muestras de un total de 13 panes, con presencia de bromatos es de 15,38 %, lo que demuestra que el control realizado por los entes oficiales de control ha ido aumentando en la última gestión, sin embargo, llama la atención que aún se encuentre la presencia de bromato de potasio, siendo que es un aditivo de uso prohibido en nuestro país. CONCLUSIONES: comparando los métodos estandarizados para el estudio, el método cualitativo para bromatos /yodatos presenta mayor eficacia que el método indirecto con el reactivo fucsina bisulfito. Al encontrar un porcentaje de panes que contiene bromato de potasio, verificamos que los controles por los entes oficiales no se realizan constantemente o no quedan registrados.


INTRODUCTION: potassium bromate is a bread improving substance that is currently prohibited for use in making bread because it is considered harmful to humans, mainly causing gastrointestinal damage. Thus, the food control bodies prohibit its use completely, as well as NB 39007: 2012 flour and derivatives-baked products-requirements in its third revision, in our country. OBJECTIVE: to determine the presence of potassium bromate in breads shipped in supermarkets in the city of La Paz. METHODS: the qualitative method for bromates/Iodates and the Indirect. Method with the fuchsin bisulfite reagent were the official methods applied for the determination of potassium bromate. RESULTS: the percentage of samples from a total of 13 breads, with the presence of bromates is 15.38%, which shows that the control carried out by the official control entities has been increasing in the last administration, however, calls the attention that the presence of potassium bromate is still found, since it is an additive forbidden in our country. CONCLUSIONS: comparing the standardized methods for the study, the Qualitative Method for Bromates / Iodates presents greater efficiency than the indirect method with the fuchsin bisulfite reagent. By finding a percentage of bread that contains potassium bromate, we verify that the controls by official entities are not carried out constantly or are not recorded.

ABSTRACT

ABSTRACT This study aimed to develop and assess the physicochemical, sensory parameters, and shelf life estimation of multicomponent snack bars based on tapioca flour, Brazil nut, and açaí or cupuassu pulp. The physicochemical composition of açaí- and cupuassu-flavored snack bars had, respectively, 0.92 and 0.99% ash, 19.22 and 17.02% lipids, 3.02 and 3.03% protein, 1.06 and 1.69% fiber, and 448 and 436 kcal/100 g energy value. The shear stress test showed the consumer needs to bite more strongly to break the açaí-flavored bar. The opposite was observed in the hardness test, in which the bite compression force during mastication was greater for the cupuassu-flavored bar. The bars had water activity below 0.6, which denotes microbiological stability. The sensory analysis ranked the bars between "liked slightly" and "liked very much," which was confirmed by the acceptability index above 75% for all attributes assessed. According to the results a significant increase in water activity over storage was observed suggest the packaging used in the tests did not present a satisfactory barrier to water vapor permeability. Only water activity was used to estimate shelf life, which was determined as 58 days and 49 days for the açaí- and cupuassu-flavored bars, respectively. Thus, the snack bars represent an alternative for athletes as well as individuals with celiac disease since they are gluten free.


RESUMEN El objetivo de este trabajo fue desarrollar y evaluar los parámetros físicos, físico-químicos, microbiológicos, sensoriales y la vida útil en estante de barras a base de harina de tapioca, castaña de Brasil y pulpa de açaí o cupuaçu. En cuanto a la composición físico-química, las barras multicomponentes sabor açaí y cupuaçu presentaron, respectivamente, 0,92 y 0,99% de cenizas, 19,22 y 17,02% de lípidos, 3,02 y 3,03% proteínas, 1,06 y 1,69% de fibras y 448 y 436 kcal/100g de valor energético. La prueba de cizallamiento y dureza mostraron que el consumidor necesita una fuerza de mordida mayor para romper la barra sabor açaí. El comportamiento contrario fue observado en la prueba de dureza donde la fuerza de compresión de la mordida, durante la masticación, fue mayor en la barra sabor cupuaçu. Para el análisis sensorial se observó que las barras evaluadas recibieron notas situadas entre las categorías "me gustó ligeramente" y "me gustó mucho", resultado comprobado por el índice de aceptabilidad con valores superiores al 75% para todos los atributos evaluados. De acuerdo con los resultados, se observó un aumento significativo en la actividad de agua durante el almacenamiento, lo que sugiere que el embalaje utilizado en las pruebas no presentó una barrera satisfactoria para la permeabilidad al vapor de agua. Para la estimación de vida de estante sólo la actividad de agua fue utilizada para los cálculos, siendo el tiempo de vida de estante determinado en 58 días para la barra sabor açaí y 49 días para la barra sabor cupuaçu. Así, las barras multicomponentes elaboradas representam una alternativa para atletas, así como para portadores de la enfermedad celíaca, visto la ausencia de gluten en su composición.

ABSTRACT

ABSTRACT The aim of this study was to develop and evaluate the antioxidant characteristics and sensory acceptance of Greek yogurt with added whole sorghum flours (WSF) from genotypes BRS305 (tannin) and BR501 (tannin-free). Five formulations were elaborated: 1) Control (without WSF); 2) 2% BR501; 3) 4% BR501; 4) 2% BRS305 and 5) 4% BRS305 and evaluated for antioxidant capacity, total anthocyanins, total phenols, condensed tannins, sensory acceptance and purchase intention. The 4% BRS305 formulation presented higher antioxidant properties, but lower sensory acceptance. No significant difference was observed for: color, flavor and overall acceptability between the control and 2% BR501; nor for texture and overall acceptability between the control and 4% BR501. Principal component analysis explained that all variables associated with antioxidant properties were positively correlated with the first major component (PC1: 82.7%). The 2% and 4% BR501 formulations were more highly correlated with PC1 (92.7%), as well as the control in relation to sensorial characteristics. The addition of WSF BRS305 improved the antioxidant properties of yogurts and the addition of WSF BR501 did not interfere with the sensory acceptance of the formulations. The similarity of the sensory acceptance of the yogurt containing WSF from the BR 501 genotype to the control, opens perspectives for the insertion of sorghum in human food, using dairy products as suitable matrices, adding potential functionality to this type of product.


RESUMEN El trabajo tuvo como propósito desarrollar y evaluar las características antioxidantes y la aceptación sensorial de yogurt griego con adición de harinas integrales de sorgo (HIS) de los genotipos BRS305 (con taninos) y BR501 (sin taninos). Cinco formulaciones fueron elaboradas: 1) Control (sin HIS); 2) 2% BR501; 3) 4% BR501; 4) 2% BRS305 y 5) 4% BRS305. Las formulaciones fueron evaluadas en función de su actividad antioxidante, antocianinas totales, fenólicos totales, taninos condensados, aceptación sensorial e intención de compra. La formulación 4% BRS305 presentó más propiedades antioxidantes, pero menor aceptación sensorial que las otras formulaciones. No se observó diferencia significativa entre el control y el 2% BR501 para el color, sabor e impresión global, ni tampoco para textura e impresión global en relación al 4% BR501. El análisis de componente principal ha explicado que todas las variables asociadas a las propiedades antioxidantes han sido positivamente correlacionadas con el primer componente principal (PC1: 82,7%). Las formulaciones 2% y 4% BR501 se han correlacionado más con el PC1 (92,7%), así como el control con las características sensoriales. La adición de HIS BRS305 ha mejorado las propiedades antioxidantes de los yogurts y la adición de HIS BR501 no ha interferido en la aceptación sensorial de las formulaciones. La similitud de la aceptación sensorial del yogurt que contiene el HIS del genotipo BR501 con el control, abre perspectivas para la inserción del sorgo en la alimentación humana, utilizando productos lácteos como matrices adecuadas, agregando funcionalidad potencial a este tipo de producto.

ABSTRACT

ABSTRACT A 33-year-old male with house dust mite allergic rhinitis and asthma reported an episode of facial and lip angioedema, dyspnea, cough and dysphagia at the age of 25, minutes after eating a mushroom ( Agaricus bisporus ) pizza. He denied any drug intake, hymenoptera stings or other possible triggers, and no identifiable cofactors were present. Since then he avoided all types of mushrooms, however an accidental contact occurred with mushroom sauce that resulted in angioedema of the lip within minutes. The allergy workup included measurements of total IgE and specific IgE to mushroom, and skin prick test to aeroallergens sources, possible food allergen sources and mushroom extract, a prick to prick test with raw and cooked A. bisporus , in addition to a SDS-PAGE and immunoblotting assay. The study revealed a specific IgE to mushroom of 0.76kUA/L positive skin prick test to mushroom extract, and prick to prick test positive to white and brown A. bisporus (raw and cooked). The immunoblotting identified two IgE binding proteins with 10kDa and 27kDa. We report a case of A. bisporus anaphylaxis probably due to primary mushroom sensitization. We detected two IgE-reactive proteins with 10kDa and 27kDa as possible culprit allergens.


RESUMO Paciente do sexo masculino, 33 anos, com asma e rinite alérgica desencadeadas por ácaros, relatou episódio de angioedema facial e labial, dispneia, tosse e disfagia aos 25 anos, minutos após a ingestão de uma pizza de cogumelo ( Agaricus bisporus ). O paciente negou consumo de medicamentos, picadas de himenópteros, ou quaisquer outros possíveis desencadeadores ou cofatores que pudessem estar presentes. Desde então, evita todos os tipos de cogumelos, até a ocorrência de um contato acidental com molho de cogumelo, que resultou em angioedema labial minutos após. O estudo imunoalergológico incluiu doseamento de IgE total e específica para cogumelos, testes cutâneos para aeroalérgenos, possíveis alérgenos alimentares e extrato de cogumelos, teste prick to prick com A. bisporus cru e cozido e teste de SDS-PAGE immunoblotting . O estudo revelou IgE específica para cogumelos de 0,76kUA/L, teste cutâneo positivo para extrato de cogumelos e teste prick to prick positivo para A. bisporus branco e castanho (cru e cozido). O immunoblotting identificou duas proteínas de ligação de IgE, de 10kDa e 27kDa. Relatamos, assim, um caso de anafilaxia por ingestão de A. bisporus , provavelmente explicado por sensibilização primária a cogumelos. Detectamos duas proteínas IgE-reativas de 10kDa e 27kDa como os possíveis alérgenos responsáveis.

ABSTRACT

ABSTRACT The need to obtain nutritious foods from new sources and lower waste in industry has created a high interest in studying different parts of plants or foods that today are considered waste, but could be considered by-products with high nutritional value with potential use in human diets. Pumpkin seeds are commonly considered as waste but they have a high content of fatty and amino acids, which when used as a by-product or ingredient can add value to food products. The aim of this work was to perform a wide review of the nutritional and functional properties of Cucurbita maxima seeds and their potential medicinal influence.


RESUMEN La necesidad de obtener alimentos nutritivos de nuevas fuentes y menores desperdicios en la industria ha generado un gran interés en el estudio de diferentes partes de plantas o alimentos que hoy en día se consideran desechos, pero que podrían considerarse subproductos con alto valor nutricional y uso potencial en alimentación humana. Las semillas de calabaza se consideran comúnmente como desechos, pero tienen un alto e importante contenido de ácidos grasos y aminoácidos, que cuando se utilizan como subproducto o ingrediente pueden aportar un alto valor agregado a los productos alimenticios. El objetivo de este trabajo es realizar una amplia revisión de las propiedades nutricionales y funcionales de las semillas de Cucurbita maxima y su potencial influencia medicinal asociada a ellas.
