Abstract

Proximate composition, fatty acid analysis and protein digestibility‐corrected amino acid score (PDCAAS) in three commercially important cephalopods of the Mediterranean sea (cuttlefish, octopus and squid) were determined. The results of the proximate analysis showed that these species had very high protein:fat ratios similar to lean beef. Docosahexaenoic, palmitic and eicosipentaenoic acid were the most abundant fatty acids among analyzed species. The amount of __n‐__3 fatty acids was higher than that of saturated, monounsaturated and __n‐__6 fatty acids. Despite the fact that cephalopods contain small amounts of fat they were found quite rich in __n‐__3 fatty acids. Finally, PDCAAS indicated that these organisms had a very good protein quality.
