摘要
利用气相色谱-质谱联用法对10 kGy范围内不同辐照剂量的清香型白酒的挥发性成分进行测定,并对白酒中挥发性成分的相对含量变化进行分析。结果表明,酸类物质(总酸)相对含量随辐照剂量增加而增加,酯类物质(总酯)相对含量随辐照剂量增加而减少,乙酸含量逐渐增加,乳酸乙酯逐渐降低,异丁醇和异戊醇呈下降趋势,乙酸、乳酸乙酯、异丁醇和异戊醇在辐照陈化白酒中的变化规律与自然陈化白酒的变化规律相似。
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.
