Determination of biogenic amines in semi-dry and semi-sweet Chinese rice wines from the Shaoxing region

Abstract

The aim of this study was to investigate the levels of nine biogenic amines in two types of Chinese rice wine (semi-dry and semi-sweet) from the Shaoxing region. Thirty-nine samples from different manufacturers were analyzed by reversed-phase high-performance liquid chromatography and ultraviolet detection after pre-column derivatization with benzoyl chloride. Serotonin and tyramine were the most prevalent amines (100%) followed by histamine, cadaverine and putrescine (95.2-88.1%). Spermine, spermidine, 2-phenylethylamine and tryptamine were not detected in any sample. The most prominent biogenic amine was serotonin followed by putrescine, tyramine, cadaverine and histamine, their mean conte..
