Abstract:Biogenic amines are low molecular weight nitrogen-containing substances widely found in fermented aquatic products.Free amino acids can be decarboxylated during fermentation of aquatic materials，producing biogenic amines.Excessive intake of biogenic amines is toxic，and can result in death.This paper summarized research from at home and abroad into the mechanisms of formation，toxicities，factors influencing formation，and methods for restricting formation of biogenic amines in fermented aquatic products，to provide a theoretical basis for targeted regulation of biogenic amines in aquatic products in the future.
