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 Potencia 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 Potencia RR (34,74%), lipids BRS 284 (22,54%) and BMX Potencia RR (21,72%) and total fiber BRS 284 (26,64%) and BMX Potencia 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 Potencia RR (865.36 mg.100g -1 ), due to local cultivation conditions having lower averages temperatures. The BRS 284 and BMX Potencia 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.
