Abstract: A preparation method and application of flaxseed plant milk with a good flavor, self-stabilization and functional activity based on interface contro is disclosed. The preparation method includes the following steps: (1) pretreating flaxseed by degumming, microwave cooking and soaking for softening in sequence for standby; (2) performing colloid grinding, enzymatic hydrolysis and slag removal on the flaxseed obtained by soaking for softening in sequence, to obtain flaxseed plant milk A; and (3) performing first high-pressure homogenization, enzyme inactivation, sterilization, and second high-pressure homogenization on the flaxseed plant milk A in sequence, to obtain stable flaxseed plant milk in long-term storage with a good flavor and functional activity based on interface control. The process of the present invention is green, and can maintain stability of a product without adding an exogenous additive.

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.
