Abstract

A method of producing soybean glycopeptides with soybean dregs as a raw material. The invention relates to a method of producing glycopeptides. The method includes the following steps: adding a proper amount of water to wet soybean dregs to prepare a suspension liquid; grinding the suspension liquid by a colloid grinder and homogenizing the suspension liquid by a high pressure homogenizer, performing thermal-treatment and reducing the temperature; adding a compound protease and an enzymolysis accelerator to perform enzymolysis, separating residue from a liquid phase; adding a CTS A solution and a CTS B solution to the liquid phase to perform flocculation, and separating the liquid phase to obtain a clear liquid; and purifying, concentrating and spray-drying the clear liquid to obtain a finish product of the soybean glycopeptides. The method has simple process, low equipment cost, high yield and high oligopeptide content and is free of emission of wastewater, waste gas and waste solid, and is suitable for being promoted and applied in enterprises producing protein isolates and soybean products.

Description

technical field [0001] The invention relates to a production method of glycopeptide, in particular to a method for producing soybean glycopeptide with bean dregs as raw material. Background technique [0002] Soybean, also known as soybean, is one of the five grains and belongs to Papilionaceae. Soybean, originally produced in China, has been cultivated for 5,000 years, and there are more than 1,000 known varieties. In the late nineteenth century, soybeans were cultivated in the Northeast Plain, Huanghuai Plain, Yangtze River Delta and Jianghan Plain. [0003] Soybean is rich in nutrients that are very beneficial to the human body, such as high protein, high fiber, high potassium, high calcium and oil, etc., and has high nutritional and economic value. my country has had the eating habit of eating soybeans and its products since ancient times. It has rich experience and relatively mature technology in the processing and handling of soybeans. [0004] Okara is a by-produc...
