Research progress of ultra-high pressure technology in storage and processing of aquatic products

Ultra-high pressure processing technology is today''s popular non-thermal processing technology, using pure physical methods of cold processing, the processing method is simple and fast. It prolongs the shelf life of aquatic products by means of normal temperature or low temperature sterilization and enzyme elimination, guarantees the quality and safety of aquatic products, and only changes the color and aroma of the materials to a small extent, and maintains the inherent nutrition, quality, flavor and freshness of the food. This paper reviewed the principles of ultra-high pressure treatment technology, the mechanism and impact of microbial and enzyme activities in aquatic products, and the effects of ultra-high pressure on the nutritional and physical properties of aquatic products. Combined with the current application and research progress of ultra-high pressure technology in the field of aquatic products, the problems and future development directions were pointed out, in order to provide references for the in-depth study of this technology.
