The demand of consumers for quality of the fruit rises, and the producer produces things having high quality, and a study to evaluate in nondestructive definitely is pushed forward. Here, we measure the spectral reflectance of the mandarin orange epidermis color as a method to perform the quality evaluation of the mandarin orange and calculate colorimetric value. We analyzed relations with brix and colorimetric value and studied a method to estimate the maturational degree before the crop nondestructively. As a result, 0.81 and high correlation were provided a mandarin orange and a coefficient of correlation of epidermis color b* that they divided into 12% from brix 6%. In this way, we confirmed the maturity of the mandarin orange and the change of the color of the immaturity with the numerical value of the color system when the distinction of the brix was possible.
