Outline of Final Research Achievements

In sugar production, which is the important industry in the Nansei Arcs, sugar cane with a lot of trash due to mechanization, and sugar factory is required for rapid process control according to the cane quality. In this study, we investigated component analysis method by near infrared spectroscopy and mid-infrared spectroscopy as a rapid component analysis method which does not require pretreatment. The spectroscopic method can be possible for any of milled juice, syrup, massecuite, and molasses. The accuracy of component analysis by infrared spectroscopy and near infrared spectroscopy seems to be no different, suggesting the possibility of improving measurement accuracy by fusion of both spectroscopic data. The efficient optimization of process control in the sugar mill can be expected by the timely feedback of information obtained the spectroscopic measurement system.
