Effect of vacuum packaging and low-dose irradiation on the microbial, chemical and sensory characteristics of chub mackerel (Scomber japonicus).

The effects of vacuum packaging followed by gamma irradiation treatment (1.5 kGy) on the shelf-life of fillets of chub mackerel (Scomber japonicus) were examined, during chill storage. The control and the treated packs were analyzed periodically for chemical (TMA, TBARS, biogenic amines) and microbial characteristics.

Total lipids and fatty acids composition of the coastal and the deep-sea common octopus (Octopus vulgaris) populations: a comparative study.

The aim of this work was to investigate biochemical differences between Octopus vulgaris caught off costal zone and from the deep-sea of the Golf of Gabès (South coast of Tunisia). In both fishing grounds, octopus total lipids constituted almost 1.5% of wet tissue showing no significant difference (p < 0.

Seasonal change of lipid and fatty acid composition of little tuna Euthynnus alletteratus-by-products.

Little tuna (Euthynnus alletteratus) is an important Mediterranean commercial fish species. In this study, the lipids of tuna filet, head, viscera, liver, and gonads fished in Tunisian waters were examined in summer and winter. Total lipid content in most organs showed a significant variation due to seasonal change.
