摘　　要：为探索清香型高粱酒加速陈化的方法,利用^(60)Co-γ射线辐照酒样,辐照剂量设置为0(CK)、1.51、3.14、4.65、7.37 kGy,检测酒样中挥发性成分,并进行感官评价。结果表明,高粱酒酯类含量随辐照剂量的增加先上升后下降,1.51 kGy和3.14 kGy处理对高粱酒陈化效果较好,辐照处理后己酸乙酯、庚酸乙酯、辛酸乙酯和柠檬烯等香味物质含量均有不同程度增加;辐照处理降低了有害化合物的数量与含量,且感官评价较CK好。清香型高粱酒陈化的适宜辐照剂量为1.5~3.0 kGy。综上所述,辐照处理可加速高粱酒的陈化,节省了传统繁琐的老熟工艺在时间与空间上的成本。本研究结果为利用γ射线辐照加速高粱酒陈化提供了理论支撑。In order to explore the new technical methods of shortening the aging duration of light aroma-type sorghum liquor,the samples were irradiated with ^(60)Co-γray,and the treatment doses were 0(CK),1.51,3.14,4.65,and 7.37 kGy.The volatile compounds in the liquor samples were detected and the sensory evaluation was carried out.The results showed that the esters content in sorghum liquor increased first and then decreased with the increase of treatment dose.The doses of 1.51 and 3.14 kGy had better effect on the aging of sorghum liquor.After irradiation treatment,the contents of flavor substances such as hexanoic ethyl ester,heptanoic ethyl ester,octanoic ethyl ester,and limonene all increased to varying degrees.These irradiation doses also reduced the type and content of harmful volatile compounds.The sensory evaluation results of these two doses were better than those of CK.In conclusion,the suggested irradiation dose of light aroma-type sorghum liquor aging is 1.5~3.0 kGy.It is evident that irradiation-accelerated aging can save time and space costs compared to the traditional cumbersome aging process and has reasonable practicability.This research provides technical support for aging of sorghum liquor throughγX-ray irradiation.
