The authors of a recent study (here – purchase required) report on the use of biogenic amines to characterise honeys from different regions of Brazil. They found that the pattern of amines in honey, including serotonin, melatonin, dopamine, histamine, putrescine and cadaverine, varied depending upon the geographic region, foraging flora and production year. The study did not report that this variation was distinctive enough be a basis for identity verification but it does give another set of data parameters that could be added into a multi component analysis panel of identification characteristics. The authors propose that amines could be used as a quality specification parameter for some honeys, as many of these compounds have perceived health benefits for consumers.
