Abstract:The adverse effects of substances with a fishy odor on the industrial production of aquatic products are gradually becoming significant.This problem has become a major restrictive factor in the processing and marketing of aquatic products.This study reviewed recent research progress on the formation mechanism of substances with fishy odors on aquatic products，as well as deodorization technologies，in terms of their physical，chemical，and biological aspects.Additionally，the advantages and disadvantages of various deodorization technologies were compared，thereby providing a valuable reference for the removal and production of substances with a fishy odor in aquatic products.
