Brewer’s Spent Grains: Possibilities of Valorization, a Review

Abstract

This review was based on updated research on how to use brewer&rsquos spent grains (BSG). The use of BSG was considered both in food, as an ingredient or using value-added components derived from brewer&rsquos spent grain, or in non-food products such as pharmaceuticals, cosmetics, construction, or food packaging. BSG is a valuable source of individual components due to its high nutritional value and low cost that is worth exploiting more to reduce food waste but also to improve human health and the environment. From the bioeconomy point of view, biological resources are transformed into bioenergetically viable and economically valuable products. The pretreatment stage of BSG biomass plays an important role in the efficiency of the extraction process and the yield obtained. The pretreatments presented in this review are both conventional and modern extraction methods, such as solvent extractions or microwave-assisted extractions, ultrasonic-assisted extractions, etc.
