Abstract

The effect on pigmentation of the skin of red sea bream Pagrus majorby astanthin and astaxanthin dipalmitate was investigated. Fish (ca. 270g) were fed the diet containing astaxanthin and astaxanthin dipalmtate (100 ppm as astaxanthin) for 1 or 2 months. The separation of carotenoids was performed on silica gel (Silica gel 60, Merck) column chromatography.<BR>The results obtained from this experiment were as follows:<BR>1) The improvement of the body color of red sea bream by supplemented astaxanthin was observed. In the group of astaxanthin, the astaxanthin content in the skin of red sea bream after 1 month increased, but after 2 months additional increase of astaxanthin could not be found.<BR>2) In the group of astaxanthin dipalmitate, the value of astaxanthin content in the skin of red sea bream after 1 or 2 months was higher than that in the group of astaxanthin. On the deposition of astaxanthin in the skin of red sea bream, astaxanthin dipalmitate was more effective than astaxanthin.
