The fatty acid composition of particulate matter from surface waters in the North Atlantic has been investigated. A high proportion is long-chain polyunsaturated acids, typical of a marine origin. The low relative abundance of iso and anteiso 15-carbon acids indicates little bacterial contribution to the particulate matter. This fatty acid distribution is in contrast to that found in estuarine particulate matter, which contains only trace amounts of the long-chain polyunsaturated acids and substantial quantities of branched chain acids.

Sebastes Mentella

Abstract Chemometric analysis of fatty acid profile in the heart tissue of redfish (Sebastes mentella, Travin 1951) from 11 locations in the waters off Norway, Faroe Islands, Iceland, and from two strata at different depths in the Irminger Sea revealed the presence of four separate stocks in the North Atlantic Ocean. The investigation has, statistically, shown: (i) a clear distinction between S. mentella on the Faroe Plateau and S. mentella in the deeps south-west of the Faroe Bank and on the Wyville Thomson Ridge; (ii) a relationship between S. mentella inhabiting the Faroe Plateau and the Norwegian Sea; and (iii) two significantly distinct stocks of S. mentella dwelling on the Icelandic Plateau. The chemometric method, consisting of methanolysis, gas chromatography of the resulting fatty acid methyl esters, and multivariate statistical treatment of the analytical data, has a discriminating power high enough to differentiate at stock level and individual level.

Abstract Objectives Beef is a rich source of branched chain fatty acids (BCFA) in the American diet. Once consumed, utilization of fatty acids depends on their lipid class in foods. Our objective is to characterize the distribution of BCFA among lipid classes in commercial ribeye steaks, specifically sampled from grass-fed, angus, and prime beef. Methods Beef was obtained from a supermarket in Austin, Texas. Samples were cut into pieces (1 mm3) and extracted by the method of Bligh and Dyer. Extracts were fractionated into triacylglycerol (TAG), phospholipids (PL), cholesterol esters (CE), and free fatty acids (FFA) by thin layer chromatography (TLC). PL were further fractionated into phosphatidylcholine (PC), lyso-PC, phosphatidylserine (PS), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and sphingomyelin (SM). Fatty acid methyl esters (FAME) were prepared from each fraction by treatment with BF3/methanol and analyzed by high resolution capillary gas chromatography (GC) with positive structure identification by MS/MS of the molecular ion. Results Total BCFA in PL of grass-fed beef is the highest (1.25 ± 0.05%, w/w; mean ± SD) compared with those in PL of other beef. Total BCFA in TAG (1.30 ± 0.37%, w/w) were not different between angus and prime beef. BCFA were detected in all lipid fractions. Anteiso-15:0, anteiso-17:0, iso-15:0, iso-16:0, iso17:0, iso-18:0 were detected in most fractions. Conclusions Total BCFA in PL of grass-fed beef is the highest (1.25 ± 0.05%, w/w; mean ± SD) compared with those in PL of other beef. Total BCFA in TAG (1.30 ± 0.37%, w/w) were not different between angus and prime beef. BCFA were detected in all lipid fractions. Anteiso-15:0, anteiso-17:0, iso-15:0, iso-16:0, iso17:0, iso-18:0 were detected in most fractions. Funding Sources This study was supported by the National Cattleman's Beef Association and the North Dakota Beef Commission.

Introduction. Deep-sea fauna of the North Atlantic has a great potential for the development of food industry. Rabbitfish (Chimaera monstrosa) is a hydrobionts that makes up a significant proportion of bycatch in the traditional trawl and longline fishery. The research objective was to determine the technochemical composition and biochemical properties of organs and tissues of rabbitfish. Study objects and methods. The size-mass and total chemical composition was performed by standard methods. The amino acid composition of proteins was determined by chromatographic separation of amino acid derivatives obtained by reaction with orthophthalic aldehyde and β-mercaptoethanol. The method of one-dimensional thin-layer chromatography made it possible to determine the fractional composition of lipids. The fatty acid composition was determined using an S-180 gas-liquid chromatograph (Yanaco, Japan). The fat-soluble vitamins were determined by the saponification of samples with alkali, extraction, and separation of the unsaponifiable part. The fractional composition of proteins became clear after a planar polyacrylamide gel electrophoresis on (MultiPhor II, Sweden). Results and discussion. The research featured the size-mass and chemical composition of body parts, the fractional and amino acid composition of proteins, as well as the fractional and fatty acid composition of lipids, vitamins, heavy metals, and organochlorine compounds in the tissues and organs of the rabbitfish. The sensory properties of the samples proved quite high. Hot smoked rabbitfish meat can be recommended for snack foods. Waste (heads, entrails, skin, cartilage, fins) makes up more than 50% of total body weight and can be used in feed production or as a protein-containing raw material for hydrolysates in microbiology, medicine, and food industry. Conclusion. The research involved a complex biochemical study of the rabbitfish organs and tissues. The performed technochemical studies made it possible to give preliminary recommendations on the directions of its most rational integrated use.
