Optimized antioxidant peptides fractions preparation and secondary structure analysis by MIR.

Abstract

The soybean protein was hydrolyzed by Alcalase Food grade (FG) 2.4 L and the optimal hydrolysis parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (RSM). The effects of reaction temperature, pH value and ratio of enzyme/soybean protein powder ([E/S]) on the 2,2-diphenyl-1-picrylhydrazyl (DPPH) of the… (More)
