Influence of oven-drying pre-treatment on the metabolic profile of extracts from brewer’s spent grains (opens in new tab)

Extracts from untreated (fresh) and treated (oven-dried and ground) BSG, the most abundant residue from the brewing industry, were investigated through UHPLC–MS/MS metabolomic analysis to evaluate the effect of biomass pretreatment and extraction conditions on their chemical composition. Three extraction conditions were applied to each starting material, and the identified compounds were grouped into eight classes based on their chemical structure. The accumulated MS signal intensity of each ...
