We utilize the Chinese non-GMO soybean to produce isolated soybean protein, the protein content of which is over 90%. It can be easily digested and absorbed and therefore supply in time the body with more protein and amino acids, which contains more nutrients than dairy and meat products and which is free from carbon hydrate and fat. Moreover, it features high water and oil solubility, gelatinousness and emulsification and can be widely used in the fields of meat product, dairy product, baking product, health product and medical subsidiary product. Following the requirement of customers at home and abroad, our company has taken the lead in developing ISP II through deep-processing on the basis of ISP. This new method helps reduce the waste due to flying dust during the application process of soybean protein as well as improves the working environment for workers. Compared with ISP, ISP II possesses the strengths of non-flying, strong gelatinization, quick dispersion and high nutrition.
