Fish collagen is mainly derived from cartilage and fish skin of deep-sea fish. Deep-sea fish is used as raw material, and enzymatic hydrolysis is carried out to produce fish collagen peptides with biological activity and small molecular weight below 1000 Dalton.
According to relevant research data, the collagen content of fish collagen is as high as 84%.
The ocean is less polluted than the land, and marine life is more nutritious, which is a good raw material for making and extracting nutritional supplements.
