Abstract

The invention provides novel antioxidant soy peptide powder and a preparation method thereof, and relates to the technical field of preparation of the soy peptide powder. The novel antioxidant soy peptide powder comprises the following components in parts by weight: 80 parts to 100 parts of soy protein powder, 2 parts to 3 parts of chitosan, 1 part to 2 parts of tea polyphenols, 1 part to 3 partsof maltodextrin, 2 parts to 4 parts of linolenic acid, and 2 parts to 3 parts of vitamin C. The soy peptide powder is prepared by utilizing the soy protein powder, the chitosan, the tea polyphenols, the maltodextrin, the linolenic acid and the vitamin C, and the bitter taste of the soy peptide powder is changed, so that the taste of the soy peptide powder during eating is improved; and meanwhile,the own antioxidation performance of the soy protein powder and antioxidant functions of eaters are obviously enhanced; and through pretreatment of protease, the activity of the protease is improved,and thus, enzymolysis on the soy protein powder can be carried out more completely, and the enzymolysis efficiency is also improved.

Description

technical field [0001] The invention relates to the technical field of soybean peptide powder preparation, in particular to a novel antioxidant soybean peptide powder and a preparation method thereof. Background technique [0002] Soybean peptide powder is composed of 2-6 amino acids. Compared with the original protein and amino acid preparations with the same composition, soybean peptide powder is easier to be absorbed by the human body. It can be absorbed directly into the small intestine without being digested by the gastrointestinal tract, and it does not Affected by physical conditions, soybean peptide powder contains a variety of bioactive peptides, which have a variety of physiological activities, including anti-oxidation, lowering blood pressure, lowering cholesterol, lowering blood fat, anti-fatigue, enhancing immunity, etc.; as a new multifunctional nutritional ingredient , soybean peptide powder can be widely used in health food, infant food, sports food, fermente...
