气相非靶向检测技术在鉴别固态法白酒与液态法白酒中的应用研究

Investigation on the Potential Rules of Solid Liquor and Liquid Liquor Industry and the Application of True and False Identification

目的:采用气相色谱法对固态法白酒和液态法白酒进行非靶向检测,结合主成分分析法,探究该方法在鉴别固态法白酒和液态法白酒方面的应用。方法:收集市场上具有代表性的固态法白酒和液态法白酒各7批次作为试验样品。取样直接上机气相色谱仪,进行非靶向检测,筛选11个变量,运用SPSS22.0软件,进行主成分分析。结果:得到两个累计贡献率达到83.636%的主成分因子,利用这两个主成分因子可以有效的区分开固态法白酒和液态法白酒。结论利用气相色谱仪非靶向分析方法结合主成分分析法,可以鉴别出固态法白酒和液态法白酒。

Objective:The non-targeted detection of solid liquor and liquid liquor was carried out by gas chromatography,and the application of this method in the identification of solid liquor and liquid liquor was explored by combining with principal component analysis.Methods:7 batches of solid liquor and liquid liquor were collected as test samples.The samples were directly taken to a gas chromatograph for non-targeted detection,and 11 variables were screened.SPSS22.0 software was used for principal component analysis.Results:Two principal component factors with a cumulative contribution rate of 83.636% can be used to distinguish solid liquor from liquid liquor.ConclusionThe solid-state liquor and liquid liquor can be distinguished by using gas chromatograph non-target analysis method and principal component analysis method.
