Nutritional quality of the protein of Vigna unguiculata L. Walp and its protein...
Frota,Karoline de Macêdo Gonçalves; Lopes,Lays Arnaud Rosal; Silva,Izabel Cristina Veras; Arêas,José Alfredo GomesABSTRACT A protein's true digestibility and amino acid composition are important characteristics for its nutritional characterisation. This study determined the true digestibility of the protein from cowpea (Vigna unguiculata L. Walp.) and of its protein isolate, and their nutritional values were estimated after correcting for the amino acid score. The protein was isolated from the defatted whole bean by its al...
Identification and quantification of antioxidant compounds in cowpea
Moreira-Araújo,Regilda Saraiva dos Reis; Sampaio,Geni Rodrigues; Soares,Rosana Aparecida Manólio; Silva,Cintia Pereira; Arêas,José Alfredo GomesABSTRACT Dietary antioxidant compounds have been widely studied because of their ability to delay or inhibit oxidative damage, which allows them to play an important role in the prevention of diseases and the promotion of health. The identification and characterization of such compounds are required before their use in humans. This study aimed to identify and quantify antioxidant compounds in the cowpea cultiva...
Chemical composition and antioxidant activity of jatobá-do-cerrado (Hymenaea st...
Silva,Cintia Pereira Da; Sousa,Mariana Séfora Bezerra; Siguemoto,Érica Sayuri; Soares,Rosana Aparecida Manólio; Arêas,José Alfredo GomesThe Brazilian Savannah, known as "Cerrado," has an extensive biodiversity, but it is under explored. Among the native vegetables is the jatobá-do-cerrado (Hymenaea stigonocarpa Mart.), a legume with great potential for exploration for its content of dietary fiber. Legumes are an important source of nutrient compounds, such as phenolic compounds and vitamins that have antioxidant properties. This study aimed at ...
Frutanos do tipo inulina e aumento da absorção de cálcio: uma revisão sistemática
Capriles,Vanessa Dias; Arêas,José Alfredo GomesRealizou-se uma revisão sistemática da literatura sobre os efeitos do consumo de frutanos do tipo inulina na absorção de cálcio. Resultados de quatro dos sete ensaios clínicos duplo-cegos controlados aleatorizados relatados neste trabalho indicam que o consumo diário da mistura de frutanos (inulina e oligofrutose 1:1) aumenta a absorção de cálcio, dependendo da idade cronológica e fisiológica, bem como do estad...
Avaliação da qualidade tecnológica de snacks obtidos por extrusão de grão integ...
Capriles,Vanessa Dias; Arêas,José Alfredo GomesApesar dos benefícios nutricionais e de seu potencial como alimento funcional, o amaranto ainda é um alimento pouco difundido no Brasil. Para o aumento do consumo desta matéria-prima, preconiza-se a sua incorporação na formulação de produtos convencionais, como os snacks extrudados que vêm sendo elaborados com a farinha de amaranto desengordurada. Pouco tem sido pesquisado sobre a extrusão direta do grão integr...
Effect of storage and processing of Brazilian flaxseed on lipid and lignan cont...
Simbalista,Renée Leão; Frota,Karoline de Macêdo Gonçalves; Soares,Rosana Aparecida Manólio; Arêas,José Alfredo GomesFlaxseed has been widely studied around the world; its incorporation into products habitually consumed by human populations has been stimulated due to its unique nutritional value. The objective of this study was to evaluate the chemical composition of Brazilian flaxseed, to analyze the stability of lipids present in whole flaxseed flour (WFF) or partially defatted flaxseed flour (DFF) stored under several temp...
Effect of incorporation of amaranth on the physical properties and nutritional ...
Lemos,Andréa dos Reis; Capriles,Vanessa Dias; Pinto e Silva,Maria Elisabeth Machado; Arêas,José Alfredo GomesAt the present celiac disease has no known cure, and its only treatment is a strict lifelong adherence to a gluten-free diet. Cheese bread is a traditional Brazilian product and a safe option for celiacs. However, like other gluten-free breads, it has inherent low levels of fibers and minerals. The objective of this study was to evaluate the effect of incorporation of whole amaranth flour on the physical proper...
Calcium bioavailability of raw and extruded amaranth grains
Ferreira,Tania Aparecida; Arêas,José Alfredo GomesCalcium bioavailability of raw and extruded amaranth grains was assessed in a biological assay in rats. Rats were fed for 28 days on diets in which raw or extruded amaranth was the only calcium source, compared to a control diet with calcium carbonate. Calcium and phosphorous levels were determined in the rats' serum during the experimental period and in the bones at the end of the experiment. Amaranth extrusio...
Effects of defatted amaranth (Amaranthus caudatus L.) snacks on lipid metabolis...
Chávez-Jáuregui,Rosa Nilda; Santos,Raul Dias; Macedo,Alessandra; Chacra,Ana Paula Marte; Martinez,Tania Leme; Arêas,José Alfredo GomesWe evaluated the effects of defatted amaranth (Amaranthus caudatus L.) snacks on plasma lipids in moderate hypercholesterolemic patients. Twenty-two subjects [30-65 years old), 11 males, with total cholesterol (TC) > 240 mg.dL-1, low-density cholesterol (LDL-c) 160-190 mg.dL-1 and plasma triglycerides (TG) < 400 mg.dL-1] were randomized in a double blind clinical trial to receive an amaranth snack (50 g/day)...
Influence of food components on lipid metabolism: scenarios and perspective on ...
Frota,Karoline de Macedo Gonçalves; Matias,Andrea Carvalheiro Guerra; Arêas,José Alfredo GomesCardiovascular diseases (CVD) are the main causes of death in the Western world. Among the risk factors that are modifiable by diet, for reducing cardiovascular disease risks, the total plasma concentrations of cholesterol, triglycerides, LDL-C, and HDL-C are the most important. Dietary measures can balance these components of the lipid profile thus reducing the risk of cardiovascular diseases. The main food co...
