N2 - This paper demonstrates the expediency of radiocarbon liquid scintillation counting for detection of synthetic ethanol adulteration in Philippine-manufactured wines/alcoholic beverages The impure wines are distinguished from the pure beverages by radiocarbon assay, taking advantage of the anticipated minor 14Carbon content of synthetic ethyl alcohol in comparison with the natural 14C abundance of the plant-derived, biogenic products Biogenic samples give 12-15 dpm/g C activities, while synthetic samples exhibits 0-2 dpm/g C activities The research moreover explores the utility of Deuterium, Oxygen 16 and 13Carbon/ 12Carbon isotope ratio analysis in the authentication of the botanical and geographical origins of beverages Initial investigations revealed the mean of δ 18O in the Metro Manila area for precipitation, surface waters and ground waters to be -609 ± 29, -159 ± 22, and -664 ± 07 per milrespectively δ2H in Metro Manila for precipitation, surface waters and ground waters were -438 ± 12,-119 ± 162, -450 ± 48 per mil respectively Vital information such as detection of illegal dilution with water, or enrichment using other sugars before and after fermentation, misrepresentation of geographical origin, and adulteration with petroleum-derived ethanol can be generated from the isotopic data (author)
