Apparent digestibility coefficients and accumulation of astaxanthin E/ Z isomers in Atlantic salmon ( Salmo salar L.) and Atlantic halibut ( Hippoglossus hippoglossus L.)

Apparent astaxanthin (3,3′-dihydroxy-β,β-carotene-4,4′-dione) digestibility coefficients (ADC) and carotenoid compositions of the muscle, liver, whole kidney and plasma were compared in Atlantic salmon ( Salmo salar) and Atlantic halibut ( Hippoglossus hippoglossus) fed a diet supplemented with 66 m...

Description
Summary:Apparent astaxanthin (3,3′-dihydroxy-β,β-carotene-4,4′-dione) digestibility coefficients (ADC) and carotenoid compositions of the muscle, liver, whole kidney and plasma were compared in Atlantic salmon ( Salmo salar) and Atlantic halibut ( Hippoglossus hippoglossus) fed a diet supplemented with 66 mg astaxanthin kg −1 dry matter for 112 days. The astaxanthin source consisted of 75% all- E-, 3% 9 Z- and 22% 13 Z-astaxanthin, of (3 R,3′ R)-, (3 R,3′ S; meso)-, and (3 S,3′ S)-astaxanthin in a 1:2:1 ratio. The ADC of astaxanthin was significantly higher in Atlantic halibut than in Atlantic salmon after 56 and 112 days of feeding ( P
