The volatile substances of six common harmful fungi in rice were detected and analyzed by gas chromatography-mass spectrometry (GC-MS). It was found that the volatile substances produced by Aspergillus aeruginosa 3.3975, Aspergillus brightens, Penicillium citri, Penicillium chrysogenum M31, Fusarium oxysporum and Fusarium toxicum during the growth of the six fungi were the main ones. It was composed of alkanes, alkenes, alcohols, ketones, aldehydes, esters, heterocycles and others. Among them, Aspergillus Aspergillus grey: 1, 3-dichlorobenzene, 1, 4-dichlorobenzene; Aspergillus leucocephala: undecane, Eucalyptus oil; Penicillium citri: 1-ethyl cyclopentene, 2-methoxy-3-(2-methylpropyl) -pyrazine; Penicillium flavum M31: o-xylene, 1, 4-dichlorobenzene. P-xylene, 1, 3-octadiene; Fusarium oxysporum: limonene, chitosan; Toxic Fusarium: 3-chloro-4-methoxybenzaldehyde, 3, 4-dimethoxybenzaldehyde. This result preliminarily showed the feasibility of precise detection of the growth of fungi by detecting the characteristic substances produced by certain fungi, and provided new basic data for the detection and control of stored grain fungi. © 2020, Dept. of JCCOA.
