The G
(green) and CIE L⁄, a⁄, and b⁄ values obtained from the image analysis sharply increased or decreased
in the CO group. And these colour values showed high correlation coefficients (>0.9) with the sensory test
results. CIE L⁄a⁄b⁄ values using a colorimeter also showed high correlation coefficients but comparatively
lower than those of image analysis
