Iguaçu e IAS-5, destinadas à alimentação humana, foram caracterizadas quanto à composição centesimal, conteúdo de aminoácidos, ácidos graxos e minerais. Os teores de fibra, proteína e óleo variaram significativamente nas amostras analisadas, enquanto que os teores de cinzas não apresentaram diferenças significativas. Com relação aos teores de minerais, o potássio foi o que obteve o maior valor, 1.824,02 mg/100 g para a cultivar Iguaçu, ficando a EMBRAPA-4 com o maior teor de cálcio, 313,93 mg/100 g. Para a composição em ácidos graxos, notou-se que a cultivar IAS-5 apresentou o maior teor de insaturados, 87,45%, enquanto que a Davis, o menor, 83,93%. A cultivar EMBRAPA-4 apresentou um teor de ácido oléico maior e de linoléico e linolênico bem menores que as demais cultivares estudadas, 39,93%, 42,46% e 4,64%, respectivamente. Os demais ácidos graxos estão de acordo com os valores encontrados na literatura no tocante a óleo de soja. Todas as cultivares estudadas apresentaram excelente balanço em aminoácidos essenciais (AAE). Os teores de cada AAE foram superiores aos da proteína padrão estabelecido pela FAO/WHO, com valor total de AAE variando de 39,5 a 45,0 g/100 g de proteína.Termos para indexação: Glycine max, caracterização química, proteína, óleo, cinzas. PROXIMATE COMPOSITION AND AMINO ACID, FATTY ACID AND MINERAL CONTENTS OF SIX SOYBEAN CULTIVARS FOR HUMAN CONSUMPTIONABSTRACT -Six soybean cultivars (Glycine max L. Merrill): IAS-4, EMBRAPA-4, Davis, BR-16, Iguaçu and IAS-5, for human consumption were characterized regarding their proximate composition and amino acid, fatty acids and mineral contents. Significant differences were observed among these varieties concerning their contents of protein, oil and fiber. However, their ash content did not show significant differences. Regarding the mineral composition, the cultivars Iguaçu and EMBRAPA-4 presented, respectively, the highest levels of potassium (1824.02 mg/100 g) and calcium (313.93 mg/100 g). It was observed that the cultivar IAS-5 presented the highest level of unsaturated fatty acids (87.45%), while the cultivar Davis, the lowest one (83.93%). The cultivar EMBRAPA-4 presented the highest level of oleic acid and levels of linoleic and linolenic acids lower than the ones obtained for the other studied cultivars (39.93%, 42.46% and 4.64%, respectively). The results obtained for the other fatty acids levels are in agreement with the ones reported for soybean oil in the literature. All six cultivars studied presented an excellent balance of essential amino acids (EAA). The contents of each EAA were higher than those presented in the reference pattern established by FAO/WHO with the total EAA ranging from 39.5 to 45.0 g/100 g of protein.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
