Carotenoids in the sea bream, Chrysaphrys major Temminck and Schlegel III : The carotenoids in mysis and the sepia of squid as the food for sea bream タイ類のカロチノイドIII : タイ餌料としてのアミおよびイカ内臓のカロチノイド TANAKA, Yoshito 田中, 淑人 KATAYAMA, Teruhisa 片山, 輝久 open access The carotenoids in mysis and the internal organs of squid were extracted, purified on the columns, characterized by absorption spectra, the behavior on the columns, absorption maxima of the reduction and co-chromatography with authentic samples. In the mysis, the existence of β-carotene, echinenone, isocryptoxanthin, lutein, zeaxanthin, canthaxanthin, astaxanthin, and crustaxanthin was confirmed. In the internal organs of squid, astaxanthin was found. The content of astaxanthin was most abundant amoung each pigment in mysis and the internal organs of squid. It was clarified that mysis and internal organs of squid were good additives to the food for sea bream in order to improve their reddish brightness. It was assumed that in mysis β-carotene would be converted to astaxanthin through the steps of isocryptoxanthin, echinenone, and canthaxanthin. 鹿児島大学 Kagoshima University 1974-12-25 eng departmental bulletin paper VoR http://hdl.handle.net/10232/13726 https://ir.kagoshima-u.ac.jp/records/7844 0453087X AN00040498 鹿児島大学水産学部紀要 Memoirs of Faculty of Fisheries Kagoshima University 23 117 122 https://ir.kagoshima-u.ac.jp/record/7844/files/AN00040498_v23_p117-122.pdf application/pdf 2.7 MB 2016-10-28 1974-12-25
