相似系统理论及气相色谱指纹数据建立茅台酒评价体系

Application of Similarity System Theory and Chromatographic Fingerprint to Establish the Evaluation System of Maotai Liquor

应用相似系统理论对茅台酒及其他类型酒气相色谱数据进行分析,计算出普通茅台酒、陈年茅台酒的相似度,同时对其他酒与茅台酒的相似性进行评价。结果表明,普通茅台酒、陈年茅台酒与各自基准值之间的相似度均大于90%,体现出了其独有的特征。其他酱香型酒与茅台酒之间的相似度均较低。对可定量的气相色谱数据进行选取,采用分别计算偏差的方法,计算出茅台酒各指纹数据的特征值,从而确定出茅台酒、陈年茅台酒指纹数据色谱特征值及其偏差范围。综合相似度判断以及指纹数据判定,建立起茅台酒的评价体系,从整体和局部上对茅台酒质量稳定性做出充分的说明。

The similarity system theory was used for the analysis of GC data of Maotai Liquor and other liquor products. Furthermore, the similarity degree of common Maotai Liquor and aged Maotai Liquor was calculated and the similarity between Maotai Liquor and other liquor products were evaluated meanwhile. The research results showed that the similarity degree of common Maotai Liquor and aged Maotai Liquor was higher than 90 % which presented the individual properties of Maotai Liquor, and the similarity between Maotai Liquor and other liquor products was low. Then the quantitative GC data were chosen to calculate the characteristic value of each fingerprint of Maotai Liquor by respective deviation calculation and further to determine the characteristic value of fingerprint of common Maotai and aged Maotai Liquor and their deviation range. Based on the similarity evaluation and fingerprint data evaluation, the evaluation system of Maotai Liquor was set up, which could fully explain the quality stability of Maotai Liquor.
