From a nutraceutical and anti-nutritional perspective, can a grain soybean cultivar be used as vegetable soybean?

Vegetable soybean has high nutritional value and offers functional benefits to human body. However, its use in cooking is still limited, mainly due to the lack of knowledge about its properties. In addition, the availability of cultivars for human consumption is reduced. Therefore, this study was co...

Zusammenfassung:Vegetable soybean has high nutritional value and offers functional benefits to human body. However, its use in cooking is still limited, mainly due to the lack of knowledge about its properties. In addition, the availability of cultivars for human consumption is reduced. Therefore, this study was conducted in Botucatu, Brazil, to assess the potential of grain soybean (GS) and dual-purpose soybean (DPS) cultivars for consumption as vegetable soybean (VS). Pods were harvested at R6 stage, and the contents of bioactive compounds (total phenolic compounds, flavonoids, antioxidant activity and proteins) and antinutritional components (nitrates, oxalate, alkaloids and tannins) were evaluated. The cultivars showed the same protein content, not differing statistically from each other, as well as for nitrate and oxalate. The content of phenolic compounds and total antioxidant activity of the SG cultivar differed statistically from the content of the DPS and VS cultivars, respectively. According to the results, the GS cultivar, with pods harvested at R6 stage, showed nutraceutical quality and contents of antinutritional compounds similar to those of the two cultivars proposed for the vegetable soybean. RESUMO: A soja-hortaliça apresenta alto valor nutritivo e oferece benefícios funcionais para o organismo humano. No entanto, seu uso na culinária ainda é limitado, principalmente devido à falta de conhecimento sobre suas propriedades. Além disso, a disponibilidade de cultivares para consumo humano é reduzida. Portanto, este estudo foi realizado em Botucatu, Brasil, com o objetivo de verificar o potencial de cultivares de soja-grão (SG) e soja de duplo propósito (SDP) para consumo como soja-hortaliça (SH). Assim, vagens foram colhidas no estádio R6, foram avaliados quanto os teores de compostos bioativos (compostos fenólicos totais, flavonoides, atividade antioxidante e proteínas) e de antinutricionais (nitratos, oxalato, alcaloides e taninos). A cultivares apresentaram mesmo teor de proteína, não diferindo estatisticamente entre si, bem como para nitrato e oxalato. O conteúdo de compostos fenólicos e atividade antioxidante total da cultivar SG, diferiu estatisticamente do conteúdo das cultivares SPD e SH, respectivamente. De acordo com os resultados, a cultivar SG, com colheita das vagens em R6, apresentou qualidade nutracêutica e teores de compostos antinutricionais compatível com as duas cultivares propostas para soja vegetal.
