It is a high-tech enterprises specialized in the development, production and sales of food-origin oligopeptides owned by Zhejiang Hai’s group. The company dedicates to the research of key integrated technology in food-origin oligopeptides industrialization. After more than a decade of systematic research, a series of technical challenges have been overcomed, including protein extraction from animals or plants resources by-products, enzyme-membrane coupling of protein hydrolyzation technology, and the engineering design. Zhejiang Hai’s bio-tech Co. Ltd takes the leading in the industrial production of food-origin oligopeptides. Series of functional nutrition ingredients have been developed, such as corn oligopeptide, soybean oligopeptide, marine fish collagen oligopeptide, filling the blank of food-origin peptide ingredients in our country and initially formed new food-origin peptide industry. At present, Hai’s bio-tech Co. Ltd has become the largest food-origin oligopeptide production base as well as the most influential company in the field of oligopeptide raw materials at home and abroad.
