Total phenolic compounds (mg gallic acid equivalents (GAE)/g sample) of defatted rice bran protein concentrates (DRBPC-1 and DRBPC-2), protein hydrolysates with alcalase (RBPH-1A and RBPH-2A) and flavorzyme (RBPH-1F and RBPH-2F), and fractions with molecular mass smaller than 3 kDa (RBPH-1A<3, RBPH-2A<3, RBPH-1F<3, and RBPH-2F<3). Values are given as the means ± standard deviation of three measurements. The same letters indicate no statistical differences (p > 0.05). Significance was estimated using one-way ANOVA.
