Chemical composition and technological properties of two soybean cultivars

Abstract

The objective of this study was to evaluate the chemical composition and technological properties of grains of soybean (Glycine max) BRS 284 and BMX Potência RR cultivars, produzed in Maua da Serra - PR, in the crop years 2011 and 2012. The proximate composition, alimentary fiber, isoflavones and technological properties were determined. Both cultivars showed high content of proteins  BRS 284 (33,24%) and BMX Potência RR (34,74%), lipids BRS 284 (22,54%) and BMX Potência RR (21,72%) and total fiber BRS 284 (26,64%) and BMX Potência RR (27,13%), being the bigger fraction constituted  of insoluble fiber. Both cultivars showed high value of total isoflavones BRS 284 (591.70 mg.100g^-1) and BMX Potência RR (865.36 mg.100g^-1), due to local cultivation conditions having lower averages temperatures. The BRS 284 and BMX Potência RR values for cultivars showed swelling volume (VI) of 4.31 mL.g^-1 and 4.12 mL.g^-1, water absorption index (IAA) of 2.75 g.g^-1 and 2.75 g.g^-1 and oil absorption index (IAO) of 2.87 g.g^-1 and 2.60 g.g^-1, respectively. The cultivars were different for moisture, lipids, protein, and total isoflavones. Both cultivars display characteristics to be used as raw material for various soybean foods.
