“…Thus, remarkable functions of PL compounds have been related to food production and pharmaceutical industries [ 63 , 64 ], these include antioxidant properties during food processing [ 65 , 66 ]. Based on their important role as lipid-soluble, chain-breaking antioxidants, tocopherol compounds have received great attention from marine technologists for their important role as lipophilic antioxidants [ 7 , 8 ]. Among them, α-tocopherol has been shown to be the most abundant in fish species [ 36 ].…”

“…According to their amphiphilic character, phospholipid (PL) compounds have shown to be valuable drug delivery systems for their high bioavailability and protecting effects on different kinds of diseases [ 5 , 6 ]. Regarding tocopherol compounds, fishery products have been described as an important source of this effective lipid-soluble antioxidant system [ 7 , 8 ].…”

The presence of bioactive compounds in European eel (Anguilla anguilla) skin was studied. Proximate and lipid class compositions and analysis of the fatty acid (FA) profile (individual FAs; FA groups, i.e., saturated, monounsaturated, and polyunsaturated; FA ratios, i.e., polyunsaturated/saturated, ω3/ω6) were determined and compared to the composition of the eel muscle. As a result, higher (p < 0.05) levels of proteins (271.6 g·kg−1), lipids (38.0 g·kg−1), ash (27.7 g·kg−1), and ω6 FAs were observed in the skin tissue. Contrary, the muscle tissue showed higher (p < 0.05) moisture, ω3 FA, and ω3/ω6 ratio values. Regarding lipid classes, a higher (p < 0.05) proportion of phospholipids (111.1 g·kg−1 lipids), free sterols (104.7 g·kg−1 lipids), α-tocopherol (274.0 mg·kg−1 lipids), and free FAs (43.6 g·kg−1 lipids) was observed in the skin tissue. No differences (p > 0.05) between both tissues could be detected for triacylglycerol and FA group (saturated, monounsaturated, and polyunsaturated) values and for the polyunsaturated/saturated FA ratio. It is concluded that European eel skin, a by-product resulting from commercial processing, can be considered a valuable source for the food and pharmaceutical industries by providing value-added constituents such as proteins, lipids, ω3 FAs, phospholipids, and α-tocopherol.

“…Such difference can be explained on the basis of seasonal variation of chemical composition (Aubourg et al ., 2021). In general, α‐tocopherol has shown to be the most abundant tocopherol compound in different kinds of substrates related to marine animals from natural diets (Piclet, 1987; Kalogeropoulos & Chiou, 2010; Kim, 2010). Contrary, a remarkable presence of other tocopherol compounds has been detected in other foods such as those obtained from vegetable sources (Munné‐Bosch & Alegre, 2002; Ali et al ., 2022).…”

“…As lipophilic antioxidants, tocopherol compounds have shown an important role in vivo (Pope et al ., 2002) and in the stability of food fat and oils (Frankel, 1998). Notably, fishery products represent an important source of this natural and most effective antioxidant system (Kalogeropoulos & Chiou, 2010; Kim, 2010).…”

SummaryThis study focused on the preparation of lipid concentrates with high contents of bioactive molecules. Different one‐step and two‐step extractions with non‐halogenated solvents (hexane, HX; isopropanol, IP) were carried out on Patagonian squid (Doryteuthis gahi) discards. As a first step, HX extractions (one, two or three times) were carried out. The resulting substrates were extracted with IP (two, three or four times). Analysis of lipid extracts included total lipid, phospholipid (PL) and tocopherol values, and fatty acid (FA) profile. HX extractions led to remarkable α‐ and γ‐tocopherol values (ca. 1400 and 23 mg kg−1 lipids, respectively); no effect (P > 0.05) of the number of HX extractions was observed. IP extracts provided high PL values (383–501 mg kg−1 lipids); the highest average values were detected with four IP extractions after three HX extractions. Values obtained for tocopherols and PLs were higher (P < 0.05) than those obtained by employing the conventional (chloroform/methanol, 1:1) lipid extraction (ca. 496 and 11 mg kg−1 lipids and 400 g kg−1 lipids, respectively). Range values detected for eicosapentaenoic and docosahexaenoic acid values and the ω3/ω6 FA ratio were similar to those obtained by the conventional procedure. A valuable procedure is proposed for obtaining PL‐ and tocopherol‐enriched concentrates from marine waste with non‐halogenated solvents.

“…8 Marine fish also provide certain vitamins and minerals such as iodine, selenium and zinc. 9,10 Fish are classified as either fatty (>10% fat), medium fat (5-10% fat), low fat (2-4% fat) or lean (<2% fat) according to the percentage fat in the muscle. 11,12 In general, marine fish species are high in n-3 PUFAs, particularly eicosapentaenoic acid (ECP, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3), as well as in monoenes such as C18:1n-9, and the saturated fatty acid C16:0 (palmitic acid).…”

Cape snoek (Thyrsites atun) is an important source of protein for people in South Africa; however, nutritional information thereof is limited. The proximate and fatty acid compositions of raw and cooked (80 °C) snoek muscles were determined according to official AOAC methods. The mean moisture, ash, total lipids and protein for raw snoek were 72.8±1.86%, 1.3±0.09%, 4.0±1.16 and 21.5±1.35%, respectively. Cape snoek is very high in palmitic acid (24.65±1.43%), oleic acid (18.21±2.64%), eicosapentaenoic acid (EPA, 9.11±2.06%) and docosahexaenoic acid (DHA, 19.70±3.25%). With the exception of total lipids, cooking significantly reduced moisture (69.40±2.03%) and ash (1.12±0.12%), and increased protein (24.47±1.39%) content. It is concluded that Cape snoek is very high in protein and can be classified as a low-fat fish which is rich in EPA and DHA.
