Oxidation products concentration was found to be lower when the immobilized lipases were added at the highest temperatures studied. The lowest oxidation indices were observed in the presence of Lipozyme RM. Although the mechanism to explain this decrease in the oxidation products is not still clear, these results might indicate that the use of these immobilized lipases in lipase-catalyzed reactions of fish oils at high temperature (90 °C) will yield higher reaction rates and also a reduction of the oxidation products formed due to oxidation of polyunsatured fatty acids 0023-6438 http://hdl.handle.net/10259/4812 10.1016/j.lwt.2018.05.032 Fish oil Omega-3 Oxidation products Commercial immobilized lipases Oxidation kinetics of sardine oil in the presence of commercial immobilized lipases commonly used as biocatalyst
