Method for preparing almond protein antioxidant peptides of little white apricot through enzymatic hydrolysis

The present invention discloses a method of making small peptides White Almond protein hydrolysis one kind of antioxidant enzyme, the following steps: a protein content of 70% -80% of small White Almond meal defatted 50 mesh crushed, defatted almond per 100g after the mixed powder and was allowed to stand 450-600mL water soak 20min, a colloid mill 1min; stirring the mixed solution to adjust the pH of 7.5-8.5, is added to the alkaline protease trypsin composite mass ratio of 3: 1 complex enzyme 3500- 4500U / g (substrate); enzymolysis to be formed was placed in a reaction vessel, a sealed reactor at 35-45 deg.] C 2.5-3h, immediately enzymolysis temperature was raised to 95 deg.] C after completion of the reaction off 10min enzyme reaction was stopped to obtain peptides were solution having antioxidant properties, efficient use of resources byproduct quality protein.
