Abstract

Nowadays the production of green beans and roasting and ground coffee in Colombia request of a scientific certification criteria that allows the access to specialized markets with prices more fair for the producer. In this way, is very important the basic characterization that it makes over the material. In this work the results of the study of green coffee thermal diffusivity, as well as its pigmentation after roasting and ground using the photoacoustic (PA) technique are shown. The analysis of these results indicates a narrow relation between the
