This research describes a first approach to analyse the effects of using high-pressure processing (HPP) as a pretreatment before frozen storage and subsequent canning of fish. For it, Atlantic Chub mackerel (Scomber colias) was subjected to HPP (200, 400 and 600 MPa for 2 min) followed by freezing (-30 degrees C for 48 h), frozen storage (-18 degrees C for 0, 3, 6, 10 or 15 months), canning and canned storage (3 months at 20 degrees C). Lipid damage development (hydrolysis and oxidation) and volatile amines formation (total and trimethylamine) were determined in canned mackerel. As a result, a marked inhibitory effect (p < 0.05) on free fatty acids content was observed in canned mackerel previously subjected to different frozen storage times. This effect increased with pressure applied. Furthermore, higher average polyene values were obtained in most canned fish previously subjected to any high-pressure treatment when compared with Control canned fish. No effect (p > 0.05) on thiobarbituric acid reactive substances and trimethylamine values was noticed related to HPP. However, increasing (p < 0.05) peroxides and fluorescent compounds contents were obtained when applying the two highest pressure levels.
