Towards Sustainable Recovery of Phenolics, Proteins, and Arabinoxylans from Brewer’s Spent Grain Through Deep Eutectic Solvents: Extraction Strategies, Structure–Function Relationships, and Food Biorefinery Perspective
Brewer’s spent grain (BSG) is the primary by-product of the brewing industry and a low-cost lignocellulosic resource rich in phenolics, proteins, and arabinoxylans (AXs). Conventional recovery methods using acids, alkalis, and organic solvents often involve energy-intensive processes, generate hazardous waste, and limi...
