DETERMINATION OF METHANOL CONTENT IN WHITE ALCOHOL CIRCULATED IN SEVERAL PROVINCES OF NORTHERN REGION IN 2017-2018
Main Article Content
Abstract
Objective: to determine methanol content in 268 unlabelled alcohol samples in
9 provinces of North region from 2017 to 2018. Method: Samples were collected
at retailed stores in downtown areas. Methanol in the samples was detected by using
gas chromatography with flame ionization detection (FID). Result: There were
129 in 268 samples containing methanol (48.1%). The concentration of methanol
ranged from 7.0 to 651.3 mg/litter of ethanol 1000. There were eight samples which
exceeded TCVN 7043:2013. Our study provided the food administrators with more
information to enhance solution to ensure food safety and prevent poisoning of spirit
containing methanol.
