Abstract:

Objective To understand the quality and safety of bulk-packaged Baijiu in Luzhou City,and provide a scientific basis for standardized production and regulation. Methods A total of 216 bulk Baijiu samples were collected from 7 districts and counties in Luzhou in 2024. Methanol,cyanide,lead,artificial sweeteners(sodium cyclamate,saccharin sodium,sucralose,acesulfame potassium,neotame),dibutyl phthalate(DBP),di(2-ethylhexyl) phthalate(DEHP),and diethyl phthalate(DEP) were determined using the methods specified in GB 2757-2012 "National Food Safety Standard Distilled Liquor and Compound Wine". 8 flavor substances namely ethyl acetate,ethyl butyrate,ethyl hexanoate,ethyl lactate,n-propanol,phenethyl alcohol,acetic acid,and hexanoic acid were detected according to GB/T 10345-2022 "Method of Analysis for Baijiu". The Spearman method was used to analyze the correlation between flavor substance content and product price. Results The overall non-compliance rate of the samples was 6.02%,with the non-compliance items being sucralose(0.46%),neotame(3.70%),and DBP(5.09%). Flavor analysis showed that the contents of ethyl acetate,ethyl lactate,ethyl hexanoate,acetic acid,and hexanoic acid were positively correlated with price(all P<0.01),while n-propanol was negatively correlated with price(P<0.01). Conclusion The overall quality and safety of bulk-packaged Baijiu in Luzhou City is good. It is recommended to continuously strengthen the quality and safety supervision of bulk Baijiu,focusing on the pollution risk of artificial sweeteners and phthalates.
