Fish collagen and collagen peptides and industrialization

In recent years, Chinese fish production reach more than 30 million tons, of which fish skin collagen occupy more than 6%. Fish skin containing up to 80% protein, the highest content is type I collagen, which is a potential raw material of extracted collagen. Fish skin collagen has a low temperature, low antigenicity, hypoallergenic, easy enzymatic and other features. For the development of a small molecular weight peptide is superior to pig and bovine collagen. Worldwide demand for collagen increase as a rate of 20% per year  and peptides industry has great prospects for development.
