Abstract: Microbial toxin in food products usually refers to the toxin produced by microbial metabolism. It includes peptide toxins, lipopolysaccharide (LPS), mycotoxins, biogenic amines and aldehyde compounds from fatty acid oxidation. This paper briefly introduces partial detection technologies at home and abroad, including polymerase chain reaction (PCR), enzyme linked immunosorbent assay (ELISA), high performance liquid chromatography (HPLC), solid-phase microextraction-gas chromatography-mass (SPME-GC-MS), solid-phase microextracton-gas chromatography-olfactometry (SPME-GC-O), etc. The detection technologies are comprehensively evaluated for their features and suitable conditions. Moreover, the recent progress of the research is summarized on their application for detecting several common microbial toxins.

Key words: peptidetoxins, lipopolysaccharide, mycotoxins, biogenic amines, aldehyde compound, detection methods
