Research Abstract	The components of the food related to the "deliciousness" are usually evaluated by the componential analysis. Component content and the kind of the component in the food are measured by this analysis. However, componential analysis is not able to analyze detailed measurement, and it needs long time to measure. We researched a method to measure two-dimensional distribution of the component in the food by using the near infrared ray (IR) image. An advantage of our method is to be able to make a visualized image of invisible components, because the component content is measured by taking subtraction of two wavelength of near IR light. Many components of the food have characteristics in the range of IR. In this research, we describe a method to measure the component of the food by using near IR image processing, and we researched application to vestibules and fruits.
