L'oxydation des lipides dans le poisson : causes, modifications et mesures de l'oxydation.

Lipid oxidation in fish-causes: changes and measurements.

Auteurs : Ifremer, FIOM, UNDELAND I.

Résumé

In fish tissue, highly unsaturated lipids are situated in close proximity to powerful catalytic and antioxidative systems. In the living fish, the two latter balance each other. During postmortem storage, several biochemical processes take place, favouring initiation of lipid oxidation resulting in the formation of an array of products affecting taste, smell, colour and texture of the fish. In the review, the types of lipids, oxygen species, catalysts and antioxidants which are critical for lipid oxidation in fish tissue are discussed. Various ways of measuring lipid oxidation are listed.
