Abstract: The volatile components of qingxiang liquor with different irradiation doses in the range of 10 kGy were determined by gas chromatography-mass spectrometry (GC-MS). The relative content of volatile components in liquor was analyzed. The results showed that the relative content of acid (total acid) increased with the increase of irradiation dose, the relative content of ester (total ester) decreased with the increase of irradiation dose, the content of acetic acid increased gradually, ethyl lactic acid decreased gradually, isobutol and isoamyl alcohol showed a downward trend, acetic acid, ethyl lactic acid, the changes of isobutylalcohol and isoamyl alcohol in irradiated aging liquor were similar to those in natural aging liquor.

Key words: irradiation, GC-MS, liquor, volatile components, relative content
