Under different reaction conditions, including time, temperature and FFA content and type (different chain lengths and unsaturation degrees), FFAs were made to interact in model systems with a commercial marine oil (cod liver oil) and two different ®sh (hake and pout) white muscles. Fluorescence assessment showed a pro-oxidant effect of all types of FFA, which increased with time, temperature and FFA content in the reaction mixtures. At 30°C a higher degree of oxidation was obtained in systems including the shorter-chain-length fatty acids (lauric and myristic) compared to systems including the longest ones (arachidic and stearic). At the same temperature an increasing pro-oxidant effect was also observed with increasing degree of fatty acid unsaturation (stearic < oleic < linoleic < linolenic). When a lower temperature (ÿ10°C) was tested, a differential pro-oxidant effect among fatty acids (chain length and unsaturation degree) was not observedThe author acknowledges the European Community for financial support through research project FAIR-CT95-1111Peer reviewedWiley-BlackwellEuropean CommissionConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201220122001info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/53051reponame:DIGITAL.CSIC.
