Abstract: Aquatic products are rich in protein and other nutrients, which are easily contaminated by microorganisms during processing or storage, leading to spoilage. Previous studies have found that this process is often accompanied by the production of a large number of biogenic amines. Further studies have shown that excessive intake of biogenic amines will cause food poisoning. Therefore, effective methods for detecting the contents of biogenic amines in aquatic products are of great significance for ensuring the safety of aquatic products. In view of this, this paper summarizes the formation mechanism and toxicity of biogenic amines and the maximum residue limits for them adopted by different countries, and discusses in depth the indirect and direct methods commonly used to detect biogenic amines, with a view to providing support for more accurate and efficient detection, prevention and control of biogenic amines.

Key words: biogenic amines; aquatic products; biogenic amine-producing bacteria; detection techniques
