Analysis of Characteristic Flavoring Compositions of Xiaoqu Liquor by Use of Decision Tree Modeling

Comparative analysis of characteristic flavoring compositions between Xiaoqu liquor and liquor of other flavor types was carried out by use of decision tree modeling-based methods including classification and bagging.The results showed that there was significant difference be-tween Xiaoqu liquor and liquor of other flavor types.On that basis,the characteristic compositions indexes of Xiaoqu liquor were investigated and it was found that the characteristic indexes of Xiaoqu liquor were mainly embodied in ethyl acetate,n-pentanol and isopentanol etc.,which could be used as reference for the formulation of national standards of Xiaoqu liquor.Moreover,the feasibility of using data processing models to analyse characteristic indexes was proved in this paper.(Tran.by YUE Yang)
