Abstract

The invention relates to soybean oligopeptide powder. The soybean oligopeptide powder comprises the following raw materials in parts by mass: 88-95% of soybean oligopeptides, 4-10% of stachyose, 0.7-1.4% of glycine, and 0.3-0.6% of aspartame. A preparation method of the soybean oligopeptide powder comprises the following steps: step 1, dispersing and hydrolyzing soybean protein isolate powder, namely blending the soybean protein isolate powder with deionized water so as to obtain protein pulp, and carrying out shearing so as to have the protein pulp dispersed and hydrated; step 2, carrying outultra-filtration while performing enzymatic hydrolysis, namely regulating the pH value of the hydrolyzed protein pulp to 8-9, adding compound protease of which the mass is equivalent to 1-4% of the mass of the soybean protein isolate powder, and carrying out enzymatic hydrolysis by performing agitation at 50-55 DEG C for 3-4 h, wherein the whole enzymatic hydrolysis process is carried in an agitation-ultrafiltration device; and step 3, obtaining a filtrate subjected to the agitation-ultrafiltration after completion of enzymatic hydrolysis, adding the stachyose, the glycine and the aspartame into the filtrate, carrying out uniform stirring, and carrying out concentrating, sterilizing and spray-drying so as to obtain the soybean oligopeptide powder. The soybean oligopeptide powder preparedby the preparation method has higher physiological activity.

Description

technical field [0001] The invention relates to a preparation method of oligopeptides, in particular to a soybean oligopeptide powder and a preparation method thereof. Background technique [0002] Soybean oligopeptides generally consist of 3-6 amino acids, and more than 80% of them have a molecular weight below 1000. The refined product after hydrolysis can be further developed into health food or food processing base material. At the same time, soybean oligopeptides have more abundant characteristics than soybean protein, mainly as follows: small molecular weight, easy to digest and absorb, almost no antigenicity; good thermal stability and water solubility, viscosity is not easy to change with concentration, etc.; Solubility is not limited by acid-base environment. [0003] Moreover, it has many physiological functions such as easy absorption and low allergenicity, lowering blood fat and cholesterol, lowering blood pressure, promoting mineral absorption and fat metaboli...
