Concentration of methanol in some alcoholic beverages marketed in venezuela by means of the GC-FID technique

Abstract:

quantifica-Gas chromatography technique with flame ionization detector (GC-FID) has been employed for the quantifica-tion tion of methanol in diverse alcoholic drinks of legal (Cocuy, Superior and Antioqueño) and clandestine (Miche, Chuchuguaza and Cacique Arco de Palo) sale in Venezuela by using the internal standard method. Additionally, the eth-anol content was quantified to validate the analysis by direct comparison with the value reported for the commercially available Cocuy. The methanol concentration was found between 76.8 and 2456.8 ppm. According to these results, the methanol concentration in 44% of the samples analyzed exceeds the permitted limit (250 ppm) indicated in the Venezuelan legal regulation COVENIN 3362-2001.
