Abstract

A method for extraction and multi-scenario utilization of flaxseed protein-polysaccharide natural mixture is disclosed, comprising:(1) raw material pretreatment; (2) extraction of mixture I; (3) multi-scenario utilization of mixture I; (4) extraction of mixture II; and (5) multi-scenario utilization of mixture II. Compared with the traditional extraction mode (such as alkali-solution and acid-isolation method) of flaxseed protein, the method of the invention can enrich the flaxseed protein more efficiently, greenly and moderately, and can co-extract polysaccharide from flaxseed meal to form the flaxseed protein-polysaccharide natural mixture. Physical field/bio-enzyme coupling ultrasonic technique solves the bottleneck problem of low extraction rate of the flaxseed protein-polysaccharide natural mixture by water extraction method. By controlling the types of physical field/enzyme, action parameters and treatment time, flaxseed protein-polysaccharide natural mixtures with different proportions can be customized and endowed with multiple functional properties, so as to satisfy the multi-scenario utilization of mixtures I and II.
