Hainan Huayan Collagen Technology Co., Ltd produces 4,000 tons of high-quality fish collagen peptide annually, the fish collagen(peptide)is a new enzymatic hydrolysis process originally created by Huayan company, which utilizes the pollution-free free material of scales and skins. Compared with the traditional acid-base hydrolysis of collagen, the enzymatic hydrolysis process of our company has many advantages: Firstly, because the enzymatic hydrolysis conditions are usually mild, there will be no variation in molecule structure and no deactivation of functional components. Secondly, the enzyme has a fix cleavage site, so it can control the molecule weight of hydrolyzed collagen and obtain hydrolysates with concentrated molecule weight distribution. Thirdly, because acid and alkali are not used in the enzymatic hydrolysis process, the enzymatic hydrolysis process is environmentally friendly and does not pollute the environment.
