Enzymatic Interesterification of Cold-Pressed Maqui (<i>Aristotelia chilensis</i> (Mol.) Stuntz) Seed Oil and Belly Oil from Rainbow Trout (<i>Oncorhynchus mykiss</i>) Through Supercritical CO₂.

ABSTRACT: A new antioxidant lipid (AL) was synthesized from rainbow trout (Oncorhynchus mykiss) belly oil and cold-pressed maqui (CPM) (Aristotelia chilensis (Mol.) Stuntz) seed oil via enzymatic interesterification using Thermomyces lanuginosus in supercritical CO₂ medium. A Box-Behnken design with 15 experiments was employed, with the independent variables being the following: belly oil/CPM oil ratio (10/90, 50/50, and 90/10, w/w), supercritical CO₂ temperature (40.0, 50.0, and 60.0 °C), and supercritical CO₂ pressure (100.0, 200.0, and 300.0 bar) for enzymatic interesterification. A multiple optimization was conducted based on the response variables yield and eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and tocopherol
