Mean values and standard deviations (error bars) of B group vitamin (B1, B3, B6, B12) contents in four different brewers’ spent grain (BSG) samples.

For each mineral, capital letters indicate homogeneous groups established by the ANOVA (p < 0.05) by comparing samples before and after in vitro digestion for each BSG sample. Note: db, dry weight.
