IDENTIFICACIÓN DE ADULTERANTES SOYA, FRÍJOL Y CEBADA EN CAFÉ TOSTADO Y MOLIDO UTILIZANDO EFA-IRTF IDENTIFICATION OF SOY, BEAN AND BARLEY ADULTERANTS IN ROASTED AND GROUND COFFEE USING FTIR-PAS
Detection and quantification of adulterants in processed coffee is very important, because some sensorial characteristics and grain size are readily reproducible with products as cereals, legumes, seeds, roots and bad quality coffee after roast and ground. In this work, spectral characteristics of medium-roasted coffee powder that was blended to different concentrations with barley, bean and soy, are defined. This was done using
