n recent decades, with the improvement of understanding of aquatic resources and the development of modern biotechnology and its application in aquatic products processing industry, bioactive small molecule collagen peptides have become the focus of research and development in aquatic product processing.
We take cod skin and fish as raw material, preparation process and the physical activity of collagen peptide were studied, established the efficient extraction of bioactive peptides, collagen orientation enzymolysis, deodorization, decolorization products of high concentration, membrane physical sterilization and ion removal and other series of key technologies based on and through the development of key equipment finally, formed a set of high purity skin collagen peptide production technology and industrial production.
The fish skin collagen peptide produced by this technology is white powder, no fishy smell, good water solubility, controllable molecular weight in 1000-5000Da, and has broad application prospects in functional food, health products, cosmetics and other fields.
