Electronic Nose for Quality Control of Colombian Coffee through the Detection of Defects in Cup Tests

Electronic noses (ENs), are used for many applications, but we must emphasize the importance of their application to foodstuffs like coffee. This paper presents a research study about the analysis of Colombian coffee samples for the detection and classification of defects (i.e., using Cup Tests), which was conducted at the Almacafe quality control laboratory in Cucuta, Colombia. The results obtained show that the application of an electronic nose called A-NOSE, may be used in the coffee industry for the cupping tests. The results show that e-nose technology can be a useful tool for quality control to evaluate the excellence of the Colombian coffee produced by National Federation of Coffee Growers.
