It was showed that pectenolone and pectenoxanthin were all found in Gonads, hepatopancreas, mantle and gill, among of them, ovary, hepatopancreas and gill possessed more carotenoid than other tissues, but no carotenoids were found in the white muscles of Yesso scallops. Hepatopancreas contains a variety other carotenoids some kind of other not identified beside pectenolone and pectenoxanthin. The result also showed that the Yesso scallop with orange muscle had more the carotenoids in a variety of tissues than the common, and the female more than the male.4 Impacts of carotenoid accumulation on morphological structure and chemical composition in orange muscle of Yesso scallopThere was no difference between the orange and white muscle obserced by conventional HE staining, while musclular fiber type and matrix density in the orange muscle was different from white ones by the TEM observation of ultra-thin slices, and there were three musclular fiber types, among of them, the loose muscular fiber was orange muscle specifically.
