Abstract

A new analytical approach to differentiate coffee botanical species and geographic origin is here reported. The method is based on the determination of the carbon isotope ratio (δ13C) of caffeine in green and in the corresponding roasted coffee, evaluated with a comprehensive approach using as second parameter the value of δ13C of the whole volatile fraction of the roasted coffee samples. The study initially evaluates the roasting effect on caffeine by using gas chromatography hyphenated to the carbon isotope ratio mass spectrometry (GC-C-IRMS). The results are then evaluated based on a novel comprehensive isotopic data evaluation (CIDE) model demonstrating that regardless the roasting effect and the different geographic origin, the coffee samples analyzed can be discriminated based on their botanical origin and in particular arabicas and robustas.
