The extraction curves areinitially linear with a slope close to the oil solubility value in pressurized CO2. Based on previous fishoil solubility data reported in the literature, a general equation has been proposed to correlate fish oilsolubility data as a function of temperature and density of CO2. Fish meal has been characterized beforeand after extraction by determining the fat and protein content and its colour. Toxic trace elements havebeen also determined by ICP-MS in the fish meal showing that most of the toxic elements remained inthe fish meal after extraction. Characterization of extracted oil was also performed by determining thefatty acid group composition and some physical parameters such as colour PB Elsevier SN 0896-8446 YR 2016 FD 2016-01 LK http://hdl.handle.net/10259/4316 UL http://hdl.handle.net/10259/4316 LA eng NO Spanish Government through MINECO (CTQ2012-39131-C02-01).
