PROBLEM TO BE SOLVED: To provide a method and a device for evaluating quality of wash-free rice, capable of classifying the wash-free rice by accurately analyzing its components and sensitively evaluating its taste and the like. SOLUTION: This device is provided with an excitation light source 6 to irradiate excitation light to an object to be measured, an object holding means 5 to hold the object to be measured at a measuring position, a light intercepting means 7 to acquire luminance of self-fluorescence obtained from transmitted light and reflected light from the object to be measured, an arithmetic and control means to compute a quantitative rate of each part of an excipulum, an aleurone layer and an albumen layer and to compute quality or the taste value of the wash-free rice, and a display means to display the value computed by the arithmetic and control means.
