| Outline of Final Research Achievements |
In order to respond to consumers’ strong interest and demand for higher internal quality of vegetables, as well as to develop the effective production management systems for improving the quality of vegetables, this research attempted to establish an non-destructive assessment approach for visualizing the firmness, soluble solids content and functional ingredients of vegetables by spectroscopic measurement. The results indicated that the spectroscopic measurement obtained by a hyperspectral camera system could be utilized to non-destructively estimate the firmness and various functional ingredients (crude fiber, carotene, lycopene and anthocyanin) of vegetables (carrot, asparagus, onion, apple, etc.). However, further improved estimation accuracy would be necessary for visualizing the distribution of these internal quality parameters.
