“…This interpretation also seems to be valid for the cephalopod E. massyae, a species that exhibited a small content of lipid. The protein concentration reported by Zlatanos et al (2006) for the common octopus, Octopus vulgaris, was ca. 75% dw.…”

ABSTRACT. The chemical profiles of Desmapsamma anchorata, Hymeniacidon heliophila (Porifera), Bunodosoma caissarum, Renilla muelleri (Cnidaria), Aplysia brasiliana, Eledone massyae, Isognomon bicolor (Mollusca), Echinaster brasiliensis, Echinometra lucunter, Holothuria grisea, Lytechinus variegatus (Echinodermata), and Phallusia nigra (Chordata) were determined. Hydrosoluble protein was the most abundant class of substances for all species, except for the ascidian Phallusia nigra, in which the carbohydrate content was higher. The percentages of hydrosoluble protein (dry weight, dw) varied widely among the invertebrates, ranging from 5.88% (R. muelleri) to 47.6% (Eledone massyae) of the dw .The carbohydrate content fluctuated from 1.3% (R. muelleri) to 18.4% (Aplysia brasiliana) of the dw. For most of the species, lipid was the second most abundant class of substances, varying from 2.8% (R. muelleri) to 25.3% (Echinaster brasiliensis) of the dw. Wide variations were also found for the invertebrates nitrogen content, with the lowest value recorded in the cnidarian R. muelleri (2.02% of the dw) and the highest in the molluscan E. massyae (12.7% of the dw). The phosphorus content of the dw varyed from 0.24% (R. muelleri) to 1.16% (E. massyae). The amino acid composition varied largely among the species, but for most of the species glycine, arginine, glutamic acid, and aspartic acid were the most abundant amino acids, with histidine and tyrosine among the less abundant amino acids. The actual content of total protein in the samples was calculated by the sum of amino acid residues, establishing dw values that fluctuated from 11.1% (R. muelleri) to 66.7% (E. massyae). The proteinaceous nitrogen content was high in all species, with an average value of 97.3% of the total nitrogen. From data of total amino acid residues and total nitrogen, specific nitrogen-to-protein conversion factors were calculated for each species. The nitrogen-to-protein conversion factors ranged from 5.10 to 6.15, with an overall average of 5.45. The use of the specific nitrogen-to-protein conversion factors established here is recommended, since it would yield more accurate determinations of total protein in the species tested in this study.

“…According to Rosa et al (2005) cephalopods stockpile lipid in the digestive tract and have low concentrations of lipid in muscles (concentrations around 5% of the dry weight). Zlatanos et al (2006) and Ben-Youssef et al (2008) reported ca. 6.0% (converted to dw) of lipid in the muscles of the octopus Octopus vulgaris from the Mediterranean Sea.…”

“…These fatty acids are of great importance to humans for the prevention of coronary heart disease (Mozaffarian et al, 2005). Although cephalopods contain low levels of fat, it is rich in n−3 fatty acids (Zlatanos et al, 2006). While, seafood can be a highly nutritious component of human diet, the contaminated, imported or domestic seafood can cause foodborne illnesses, with problems ranging from mild gastrointestinal discomfort to neurological damage (GAO, 2001).…”

ABSTRACTarious cephalopods are available for seafood consumers in the Suez Canal area either caught from the Suez Canal and stored in ice during transporting and marketing or imported and sold frozen in retail market. The lower price of imported cephalopods compared with the fresh ones makes it more demanded by consumers, restaurants and hotels. The objective of this study is to evaluate the quality and safety of fresh/chilled squid (Uroteuthis duvauceli) and cuttlefish (Sepia pharaonis) compared to frozen imported squid in the Egyptian market through chemical, biochemical and bacteriological analyses. The chemical analysis revealed that the mantle tissue pH, volatile base nitrogen (VBN) and trimethylamine (TMA) in frozen squid were significantly higher (P < 0.05) than that in fresh/chilled samples. The biochemical analysis showed that the crude protein content (% dry weight) was significantly lower (P < 0.05) (14.2±0.73%) in frozen samples than that in fresh squid and cuttlefish (17.25±0.41% & 19.95±0.55% respectively). The total lipid content was generally low, ranging from 0.39 -1.77% in all samples. Most of saturated fatty acid content of the three samples was presented as C16:0, monounsaturated fatty acid content as C18:1 and polyunsaturated fatty acid (PUFA) content as eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic (DHA, C22:6n-3). EPA and DHA contents were significantly lower (P < 0.05) in frozen squid than in fresh samples. The major essential amino acids (EAA) in the three samples were lysine, arginine, and leucine. The major non-essential amino acids (NEAA) were glutamic acid, aspartic acid and glycine. EAA and NEAA values were significantly lower (P < 0.05) in frozen squid than in fresh cuttlefish. Bacteriological results suggest that hydrogen sulphide producing bacteria constituted a significant proportion of the total spoilage flora in frozen samples, while Pseudomonas sp. constituted a major part of the spoilage flora of fresh samples. An overall look into the data obtained showed that there might be significant health hazards to humans from consuming imported frozen squid besides its much lower nutritional value than fresh samples.

“…Em Foram observados altos níveis de ácido palmítico (C16:0), com valores variando decrescentemente ao longo do tempo (16,15 a 11,23%); e esteárico (C 18:0), o qual apresentou um teor expressivo no mês de julho (16,36%). Zlatanos et al (2006), avaliando a composição química de cefalópodes do Mediterrâneo, inclusive octópodes, indicaram que os ácidos graxos mais abundantes eram os ácidos docosahexaenoico, o palmítico e o eicosapentaenoico. Os níveis de C16:0, nesta pesquisa, estão abaixo daqueles revelados por Domínguez, Cortés e Várquez (2004), 16,5 a 21,6%, em juvenis de polvo e dos reportados por Sinanoglou e Miniadis-Meimaroglou (1998), 17,27 a 26,66%, em cefalópodes do Mediterrâneo.…”
