In the results of the image analysis, the G and CIE L ⁄ a ⁄ b ⁄ values showed a high correlation coefficient with sensory test results (over 0.9). CIE L ⁄ a ⁄ b ⁄ values using a colorimeter also showed high correlation coefficients but were comparatively lower than
those were of image analysis (except CIE a ⁄ values)
