Abstract: Low-value aquatic products and by-product of fish can not be fully utilized by traditional processing technology, resulting in a waste of resources. As a safe, efficient and speedy processing technology， proteases digestion technology is widely used to improve product efficiency and product quality on the processing of aquatic products. This paper reviews the application status of proteases on the processing of low-value aquatic products and by-product of fish, especially in hydrolyzing fish protein, extracting biologically active substances and preparing aquatic flavouring. It also proposed some precautions on the processing of protease digestion and predicted the development of proteases aim to as a reference for aquatic products processing.

Key words: proteases, aquatic product, processing, application
