Embodiment 1

[0012] Embodiment 1: Take 300 kg of curd milk with a solid content of 10%, apply 10% hydrochloric acid to adjust the pH value to about 2, and after fully dissolving by shearing, transfer to the reactor, heat to 45° C., add 240 g of acid protease, Carry out sufficient hydrolysis for 60 minutes, then add 30 g of phytase to react for 30 minutes, steam heat to 80 ° C for 30 minutes, pass through the average value of 25 mpa, and then spray dry to obtain acidic soybean protein.

Embodiment 2

[0013] Embodiment 2: Take 300 kg of curd milk with a solid content of 15%, apply 10% hydrochloric acid to adjust the pH value to about 2, and after fully dissolving by shearing, homogenize at 20 MPa, transfer to the reactor, heat to 45 ° C, add 360g of acid protease was fully hydrolyzed for 60min, then 45g of phytase was added to react for 30min, steam heated to 80°C for 30min, homogenized at 25mpa, and then spray-dried to obtain acid soybean protein.

Embodiment 3

[0014] Embodiment 3: Take 300 kg of curd milk with a solid content of 15%, use 10% hydrochloric acid to adjust the pH value to about 2, and after shearing and fully dissolving, homogenize at 20 MPa, transfer to the reactor, heat to 50 ° C, add 360g of acid protease was fully hydrolyzed for 60min, then 45g of phytase was added to react for 30min, steam heated to 80°C for 30min, homogenized at 25mpa, and then spray-dried to obtain acid soybean protein.

[0015] Application in dairy products: Take an appropriate amount of soybean acidic protein powder and add it to the acid-adjusted protein emulsion, heat it and homogenize it to make formulated acidic milk, increase the protein content in dairy products, and complement animal protein. Powdered acidic soybean protein can be obtained by processing.

Abstract

The invention provides a soybean acidic albumen powder production technology, mainly comprising the following steps: adding hydrochloric acid with the concentration of 10% in soybean acid precipitation curd lactoprotein to keep the mixture with the pH value of about 2.0 for 30 min; heating the mixture to 35-50 DEG C; adding acid protease preparation and reacting for 60 min; adding phytase and reacting for 20 min; heating to 80 DEG C for 30 min; carrying out physical modification on the obtained proteolysis solution by a high-pressure viscolizer; and carrying out spray drying to obtain the soybean acidic albumen powder. The invention has the advantages of simple technology and mass production. The dissolubility of the acidic albumen powder is improved, the stability of the acidic albumen powder under the acidic condition is enhanced, and the application range of the acidic albumen powder is widened.

Description

Technical field [0001] The invention relates to a production process of protein powder, in particular to a production process of protein powder using soybean as raw material. Background technique [0002] The application of soybean protein in dairy beverages has already started in China. However, the types of soybean protein entering the dairy market are relatively small, and the functions are not perfect, which brings a lot of inconvenience to the application. For example, existing soy protein isolate products have problems such as deep color and yellow precipitation. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art and the diversification of the market, based on the production process of soybean protein isolate, through physical, chemical and biochemical modification methods, and provide a production process of soybean acidic protein powder . [0004] The technical scheme adopted in the present inv...
