in the percentage of fatty acids in oysters after HPP at 260, 500 and
800 MPa. Also coinciding with our results,Rodríguez-Alcalá, Harte,
and Fontecha (2009)found no changes in the proportions of fatty
acids, in general, nor in those of CLA, in particular, in high pressure
homogenized cow’s, ewe’s or goat’s milks. CLA isomers can easily
suffer from isomerisation processes due to temperature, resulting
in altered ratio between isomers. The present results indicate that
pressure does not cause appreciable isomerisation of CLA in human
milk
