The Silent Revolution of Brewers Spent Grain: MeatFood Innovations Through Circularity, Resource Recovery, and Nutritional Synergy—A Review

Brewer’s spent grain enhances nutritional quality by increasing fiber and plant-based proteins and reducing the need for synthetic additives. Technologies such as extrusion and fermentation transform BSG into functional ingredients that improve texture and stability. A significant increase in antioxidant capacity was observed in enriched foods; for example, in burgers, BSG improved fiber and protein levels, while decreasing fat and calories without negatively affecting sensory acceptance.
