| Outline of Final Research Achievements |
Texture, the physical "taste" of food, is important when evaluating its taste and is an indispensable index for evaluating its quality. This research reports the development of a rapid technique for measuring the physical "taste" of food using near infrared spectroscopy by constructing a system for measuring the NIR spectrum of foods of various shapes. A significant relationship between the texture of food and its near infrared spectra were clearly shown using chemometrics. The textural attributes, hardness and elasticity, were highly correlated with the near infrared spectra of the foods. These results show that near infrared spectroscopy can be applied to the non-destructive measurement of texture, the physical "taste" of food.
