Analysis of Methanol Content in Baijiu in Zhangjiajie City in 2023
An accurate and reliable internal standard method for the determination of methanol in Baijiu samples is established,and 48 Baijiu samples from Zhangjiajie city of Hunan province in 2023 are analyzed and detected.The results show that the detection rate of methanol in the whole Baijiu sample is not high,the detection rate of methanol in bottle Baijiu is relatively low(7.69%),and the detection rate of methanol in bulk Baijiu is relatively high(36.36%).In addition,the methanol content of Baijiu is not only related to the production process,production equipment,but also closely related to the type of raw materials.The methanol detection rate of sorghum wine in bulk Baijiu is higher than that of rice wine,grain wine and corn wine.The source of methanol may be the raw material itself,the production process is not properly controlled,or it may be human factors.Therefore,we should continue to strengthen the supervision of the production and sales of Baijiu,and increase the inspection and testing of Baijiu samples to ensure the safety of consumers.
