以能量为1.5 MeV/u，剂量分别为500，750，1000，1250，1500 Gy的电子束对1，2，4，6，8年等5种年份浓香型白酒进行辐照处理；扫描各酒样200～400 nm波段的紫外光谱，根据紫外光谱图的差异，计算了280～300 nm波段的光谱曲线相似度，分析光谱曲线变化规律。结果表明，对于前4种白酒，对照样与辐照样光谱曲线相似度值越小，催陈效果越好；白酒存放时间越久，酒体风格转向老熟所需剂量越小，越容易达到最佳催陈效果；对于8年白酒，辐照剂量超过750 Gy后，白酒体系动态平衡被打破，各单体物质增加，出现返生现象。因此，电子束辐照技术对低年份浓香型白酒催陈效果显著，是一种先进、高效的催陈方法。
Electron beams were employed to irradiate liquor samples in various doses to study aging effects. Five samples which had been stored for 1, 2, 4, 6, 8 years were exposed to 500, 750, 1 000, 1 250, and 1 500 Gy doses of electron beams (1.5 MeV/u). After irradiation, liquor samples were scanned spectrophotometrically from 200 nm to 400 nm. According to the difference of the UV spectra, the spectral curve similarities from 280 nm to 300 nm and the change regulations were analyzed. The results showed that the less spectral curve similarities between control samples and irradiation samples were, the better the aging effects of liquor were;The longer the liquor were stored, the lower doses were required to reach the optimum aging effect. For eight year stored liquor, the dynamic balance of liquor system was broken and the monomer material increased when the doses were more than 750 Gy, which implied the retrogradation of liquor aging phenomena were clear. In conclusion, the electron beam irradiation has significant aging effect on short year Luzhou-flavor liquor and is an effective method for aging liquor.
