Abstract: Paphia undulate is one of shellfish which have higher economic value. Foot tissue is an important edible parts of Paphia undulate. The present study examined the total carotenoid content (TCC) and color index L *(brightness), a *(values of red, green), b *(values of yellow, blue) of 91 P. undulate foot tissue samples. There are great differences in TCC and color index among individuals. The range of TCC in different individuals was 1.78 ~ 15.72 μg / g, and the fluctuation ranges of color index L *, a *, b * were 48.21 ~ 56.31, -0.32 ~ 10.46, 16.56 ~ 30.29. Statistical analysis showed that TCC and color index L *, a *, b * have highly significant correlation (P<0.01), the correlation coefficients were -0.733, 0.685, 0.775 respectively. The results of this study provided important reference data for selecting high content carotenoid in P. undulate breeding.
