摘　　要：In order to extract the scarce natural liquor flavoring which is the dream of many liquor factories from yellow water,this research first added a proper amount of food-grade entrainer ethanol into yellow water,to form yellow water containing high content of ethanol.Then,the yellow water was subjected to azeotropic distillation and catalytic esterification,obtaining natural acetaldehyde,ethyl formate,ethyl acetate and esterification liquid containing various compounds that can influence the flavor of liquor.In the esterification liquid,the contents of ethyl propionate,ethyl butyrate,ethyl valerate,ethyl lactate and ethyl hexanoate are as higher as 19.0,46.5,1.5,39.8 and 137.1 g/L,respectively.The esterification liquid prepared by one fraction of yellow water can blend 9.14 fractions of common liquor into top-grade Luzhou-flavor liquor.Therefore,yellow water has great recycling value.In order to extract the scarce natural liquor flavoring which is the dream of many liquor factories from yellow water,this research first added a proper amount of food-grade entrainer ethanol into yellow water,to form yellow water containing high content of ethanol.Then,the yellow water was subjected to azeotropic distillation and catalytic esterification,obtaining natural acetaldehyde,ethyl formate,ethyl acetate and esterification liquid containing various compounds that can influence the flavor of liquor.In the esterification liquid,the contents of ethyl propionate,ethyl butyrate,ethyl valerate,ethyl lactate and ethyl hexanoate are as higher as 19.0,46.5,1.5,39.8 and 137.1 g/L,respectively.The esterification liquid prepared by one fraction of yellow water can blend 9.14 fractions of common liquor into top-grade Luzhou-flavor liquor.Therefore,yellow water has great recycling value.
