Extraction Method of β-Glucan from Barley Distilling Lees
β-glucan has significant health benefits,improving gut health and immune regulation.In this paper,the common extraction methods of β-glucan from barley distiller's lees were described,and the traditional solvent extraction,enzymatic extraction and microwave-assisted extraction techniques were deeply analyzed and optimized.The extraction efficiency and quality of β-glucan were significantly improved,and the high-value utilization of agricultural by-products was promoted,which provided important scientific basis and technical support for the application of β-glucan in food and medicine fields.
