Other Title
Occurrence of 2-phenylethylamine and its derivates in cocoas and chocolates
Abstract
2-Phenylethylamine was extracted from cocoa nibs and chocolates and analysed by coupled gas chromatography-mass spectroscopy. The amine concentration increases in fermentation of cocoa and decreased during roasting and alkalization Its concentration in chocolates is dependent on non-fat cocoa contents. Previously unreported aldimines were found in cocoa powders, which arise from the condensation of phenylethylamine and aldehydes. The main component of these products is N-phenylmethyl-N-phenylmethylene amine (CAS 3240-95-7).
