s: PBS-soluble fraction; d: direct soluble fraction; b: bioaccessible fraction (after cholestyramine treatment). Means followed by different superscript letters indicate significant differences between the groups (P < 0.05). Repeated superscript letters indicate that the means were not significantly different (P > 0.05). Greek letters: Tukey test, all samples; Capital letters: Tukey test, among DBs, DBd and DBb.
