摘　　要：目的探讨能够区分固态与非固态发酵白酒的简单易测指标。方法测定12种白酒的电导率、旋光度、吸光度等指标,并对数据进行分析。结果酱香型固态发酵白酒电导率均值为64.72μs/cm,非固态发酵白酒的电导率均值为38.27μs/cm,具有极显著性差异(P<0.01);酱香型固态发酵白酒旋光度均值为0.050°,非固态发酵白酒的旋光度均值为0.022°,具有显著性差异(P<0.05);通过测得的吸光度得到了每种酒自身的指纹图谱,经过数据计算,得到固态与非固态发酵白酒之间的相似度均小于0.900。结论电导率、旋光度、吸光度可作为区分固态与非固态发酵白酒的指标。Objective To explore the simple and easy indexes for distinguishing solid and non-solid fermentation liquor. Methods The electric conductivity,rotation,absorbance and other indicators of 12 kinds of liquor were measured and the data were analyzed. Results The average electrical conductivity of maotai-flavor solid fermentation liquor was 64.72 μs/cm,and the average electrical conductivity of non-solid fermentation liquor was 38.27 μs/cm,showing an extremely significant difference(P<0.01). The average specific rotation of maotai-flavor solid fermentation liquor was 0.050°,and the average specific rotation of non-solid fermentation liquor was 0.022° with significant difference(P<0.05). The absorbance was measured to get a fingerprint of each wine itself,the similarity between solid and non-solid fermented liquor was less than 0.900 after data calculation. Conclusion Electrical conductivity,optical rotation,and absorbance can be used as indicators to distinguish solid and non-solid fermentation liquor.
