Abstract

The invention discloses a separation and purification method of beta-glucan, and the method comprises the following steps: (1) extraction of a beta-glucan solution; (2) filtration; (3) defatting and enzyme deactivation; (4) refiltration; and (5) pressure filtration. When the method is used for separation and purification of the beta-glucan, the molecular structure and chemical quality of the beta-glucan cannot be destroyed, the purity and yield of the beta-glucan can be effectively improved, and the whole separation process is pollution-free, green, environment-friendly and easy to realize industrial popularization.

Description

technical field [0001] The invention belongs to the technical field of separation and purification, and in particular relates to a separation and purification method of β-glucan. Background technique [0002] Studies in recent years have shown that β-glucan has the main functions of lowering cholesterol, lowering blood fat, lowering blood sugar and improving human immunity, and it is processed into health products. At present, there have been studies on the extraction of β-glucan from cereals, barley and other crops. [0003] At present, the methods for extracting β-glucan mainly include hot water method, acid method, alkali method and ultrasonic method. When considering which extraction method to choose, factors such as extraction rate and purity of β-glucan, avoidance of enzymatic hydrolysis of β-glucan, production cost, and ease of industrialization need to be considered. [0004] At present, there is no method for separating and purifying β-glucan without destroying th...
