Abstract
The invention discloses a walnut polypeptide and a preparation method and application thereof. The walnut polypeptide is prepared through enzymolysis of walnut protein powder by special enzyme for hydrolysis of plant protein, enzyme deactivation, filtration, filtrate concentration, and drying, wherein the walnut protein powder is extracted from walnut cake powder obtained by smashing walnut cake dreg, the enzymolysis conditions for the special enzyme for hydrolysis of plant protein are as follows: the concentration of a substrate is 3-30% (mass), the mass fraction of the enzyme is 0.005-10%, the enzymolysis temperature is 25-70DEG C, the pH value for enzymolysis is 7.5-12.0, and the enzymolysis time is 2-30 hours. The walnut polypeptide prepared by the method has both oxidation resistance and good antihyperlipidemic effect, and has a good application prospect in preparation of natural nontoxic antioxidant drugs or health products.
