中文摘要:

      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64.72 μs/cm, 非固态发酵白酒的电导率均值为38.27 μs/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。

英文摘要:

      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.
