摘　　要：黄酒有5000多年的悠久历史,是中国特色的酒类,被称为"国酒",绍兴黄酒在中国黄酒中具有代表性。实验发现,绍兴加饭系列黄酒在适当的紫外波长激励下产生荧光光谱,文章运用三维等高线和二维荧光分析方法给出了整体和细部的比较分析。得出三种陈年黄酒在波长400～680nm范围内存在较宽荧光峰的荧光光谱。3年陈、5年陈、8年陈酒的荧光峰分别在504,488,505nm,最佳激发波长都在370nm附近。初步阐述了其产生荧光的机理,解释了三种年份黄酒荧光图谱的相似与区别,并分析了产生较宽荧光峰的原因,为黄酒的特征标识、品牌鉴定、年代鉴别、黄酒食用安全等研究提供了有科学意义的参考。Chinese rice wine has a history of more than 5 000 years, only in China, which is called ＂Nation Wine＂, and Shao Xing Chinese rice wine is a representative of it. The fluorescence spectra of 3 kinds of Shao Xing Chinese rice wine with different storage age induced by suitable UV-light were obtained in the present paper through experiment. The authors compared and analyzed them comprehensively by using three dimensional contour and two dimensional fluorescence technique, and found that their best induced light was all in the vicinity of 370 nm. The peak wavelength of 3 year storage age wine was 504 nm, while 488 nm and 505 nm were for 5 and 8 year storage age wine respectively. The emitted fluorescence existed in 400 to 680 nm, which had wide peak. More over, the emitting mechanism of Shao Xing Chinese rice wine was discussed. The authors also have explained the similarity and difference of fluorescence spectra among the 3 kinds of wine. The reason for wide fluorescence peak was also analyzed. This investigation contributes to the study of the characteristic, year detection and food safety of Chinese rice wine.
