Overview of research progress on new processing technologies for aquatic products

China is rich in aquatic resources and the aquatic processing industry is developing rapidly, and the market potential of products produced using various aquatic raw materials is huge. The socio-economic development and the improvement of people's consumption level have put forward higher requirements for aquatic products, which further promote the technological innovation of related processing. The article classifies aquatic products into six categories: fish, shellfish, algae, crustaceans, echinoderms and cephalopods, and introduces the technological innovations and applications in freezing and preservation, sterilization, and by-product utilization in recent years, respectively, to provide reference for the continued development of aquatic products processing industry in the future.
