Research Progress of Protein Polypeptides Extraction and Bioactivities from Shrimp Processing By-products

With the increasing demand of the society for aquatic products, the expansion of shrimp industry, it gives rise to a large amount of shrimp by-products waste, such as shrimp heads, shrimp shell, shrimp feet, and low-value ones, which contains a large amount of nutrients. In this paper, the extraction technology and bioactivities of protein polypeptides from several shrimp by-products are summarized, which provides a reference for further efficient development and utilization of shrimp by-products. The active protein polypeptides extracted from shrimp and its by-products have broad application potential and market prospects in the development and utilization of functional foods.
