An integrated approach to the rum identification

Abstract

In our study, rapid methods were developed for the quantitative determination of cations (sodium, potassium, ammonium, calcium, magnesium) and anions (chlorides, nitrites, nitrates, phosphates, sulfates) using ion chromatography with conductometric detection; phenolic and furan compounds (gallic acid, ellagic acid, vanillin, syringaldehyde, vanillic acid, syringic acid, furfural, 5-HMF, coniferyl aldehyde, sinapaldehyde) by high performance liquid chromatography with spectrophotometric detection; volatile organic impurities (acetaldehyde, ethyl acetate, acetal, methanol, 1-propanol, isobutanol, 2-methylbutanol, 3-methylbutanol) by gas chromatography with flame ionization detection. The developed methods will allow monitoring the technological process of rum production, studying the aging dynamics, and identifying counterfeit products.
