Once sacrificed, individual fishes were kept frozen at –18 °C for up to 18 months and then analyses were carried out on the frozen salmon muscle. The feeding of diet II led to frozen samples showing higher contents of sarcoplasmic proteins and γ- and δ-tocopherols when compared to their counterparts previously fed with diet I. No effect of dietary antioxidant profile could be detected on proximate composition, α-tocopherol and astaxanthin contents or color (L*, a*, b*) parameters. Concerning the fatty acid composition, the fish samples corresponding to diet II showed higher C22:6ω3 and monounsaturated contents, but lower C20:5ω3 and saturated contents when compared to their counterparts from diet I.The research was carried out according to the Chilean-Spanish Cooperation Program “Universidad de Chile-Consejo Superior de Investigaciones Científicas (CSIC)” (Project CSIC-22/05-05 and Project 2004 CL 0038, respectively) and funded by the Domeyko Project 2010-VID-Universidad de Chile.Peer reviewedCSIC - Instituto de la Grasa (IG)201320132013info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/78828reponame:DIGITAL.CSIC.
