“…HPLC is the preferred method but, however, it is necessary to increase the sensitivity of the analytical method by derivatizing the amines prior to their analysis, because they lack an easily detectable common chromophore. The determination of biogenic amines in wines and beers has been carried out mostly by HPLC [3, 7, 12, 19, 30 38, 40, 44] after derivatization with reagents such as o-phthalaldehyde [7,12,30,31,37,38,44] dansylchloride (Dns-CI) [19,40] or dabsylchloride [35]. O-phthalaldehyde has a disadvantage that it reacts only with primary amines and their fluorescent derivatives are unstable, while dabsyl-and Dns-C1 react with both primary and secondary amino groups providing stable derivatives.…”
