In this study the separation of eight biogenic amines (cadaverine, serotonin, histamine, spermidine, spermine, tyramine, putrescine and -phenylethylamine) by an LC method with evaporative light scattering detection (ELSD) was performed. The LC–ELSD method was validated by comparison of the results with those obtained through LC–UV determination, based on a pre-column dansyl chloride derivatisation step and the recorded data showed as both analytical methods can be interchangeably used for biogenic amines determination. The analysis of several samples of fair trade cocoa-derivatives, coupled with results on organic cocoa-based products previously obtained, showed that both classes of samples always contain less amines concentrations in comparison with their conventional counterparts, supporting the idea that BAs can be regarded as cocoa quality markers.

Abstract
In this study the separation of eight biogenic amines (cadaverine, serotonin, histamine, spermidine, spermine, tyramine, putrescine and -phenylethylamine) by an LC method with evaporative light scattering detection (ELSD) was performed. The LC–ELSD method was validated by comparison of the results with those obtained through LC–UV determination, based on a pre-column dansyl chloride derivatisation step and the recorded data showed as both analytical methods can be interchangeably used for biogenic amines determination. The analysis of several samples of fair trade cocoa-derivatives, coupled with results on organic cocoa-based products previously obtained, showed that both classes of samples always contain less amines concentrations in comparison with their conventional counterparts, supporting the idea that BAs can be regarded as cocoa quality markers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
