| Abstract: | To make up a defect of current food safety testing technology, gas chromatography-mass spectrometry technology (GC-MS) combined with headspace solid phase microextraction (HS/SPME) was established to explore the volatile metabolites of Aspergillus flavus. Then the differential metabolites and their metabolic pathways of Aspergillus flavus in dried bean curd were analyzed by metabonomics and genomics approaches. The results showed that the differential metabolites of Aspergillus flavus contained 1,2,3-trimethyl-benzene, mesitylene, ethanol, methyl hexadecanoate, 2,4-ditert-butylphenol, acetic acid, trichloromethane, 1-butanol and 1-methyl-3-(1-methylethyl)-benzene. Particularly, acetic acid, ethanol and 1-butanol played key roles in the metabolic network of Aspergillus flavus. |
