Abstract

La présente invention concerne un système de mesure de chromaticité de torréfaction de café et un procédé de mesure de celle-ci. La présente invention concerne un colorimètre de café tel que quiconque peut facilement mesurer la valeur de chromaticité de torréfaction de grains de café en utilisant un dispositif portable tel qu'un téléphone intelligent. Par conséquent, il est possible de fournir ou de recevoir du café ayant un degré élevé de fiabilité tout en permettant à quiconque de distinguer facilement le degré de torréfaction de grains de café. De plus, il est possible de développer la torréfaction en ligne, et l'on peut s'attendre à avoir un effet qui aide à garantir une qualité de torréfaction uniforme.
