Mean values and standard deviations (error bars) of the macro-mineral (Na, K, Ca, and Mg) contents in four different brewers’ spent grain (BSG) samples. For each mineral, small letters indicate homogeneous groups established by the ANOVA (p < 0.05) by comparing BSGs before and after in vitro digestion. 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.
