Abstract Background The research was carried out to assess the lipid characteristics of oil extracted from the head and gills of Claris macrocephalus and Scomber scombrus. Results The results confirmed the presence of C16:0, C18:0, C18:1, C18:2, C18:3, C22:6 as the major fatty acids. Titus fish head (TFHD) oil had a total saturated fatty acid (TSFA) of 40.804 ± 0.002% of which C16:0 and C18:0 were the most dominant fatty acids present while the total monounsaturated fatty (TMUFA) acids present in the oil was 33.853 ± 0.001%. The total polyunsaturated fatty acid (TPUFA) content of the TFHD oil sample was found to be 25.368 ± 0.002%. The results revealed that the total unsaturated fatty acid (TUFA) present in the TFHD was higher than the TSFA. The results obtained for Titus fish gills (TFGL) oil sample followed the same trend as observed in the head sample. The results showed that the four (4) oil samples contain high level of palmitic acid (C16:0) and stearic acid (C18:0) both of which are saturated fatty acids (SFA). The main MUFA identified was C18:1 (cis-6) and ranged from 14.120 ± 0.004 to 20.418 ± 0.002% for TFHD, TFGL, CFHD, CFGL and oleic acid (C18:1) ranged from 10.297 ± 0.001 to 11.570 ± 0.003% for TFHD, TFGL, CFHD and CFGL. Conclusions Oils of CFHD and TFHD showed higher peroxide values indicating suitability for human consumption.

Excessive human consumption of saturated fatty acids and possibly cholesterol is thought to increase the risk of occlusive vascular disease. This has focused attention on ruminant tissues which tend to contain high proportions of saturated fatty acids compared with other meat species, although their cholesterol contents are reported to be quite similar. However, there have been claims, apparently unsubstantiated, that vension has a low cholesterol content and is a healthy food. The aims of this study were to determine the cholesterol contents of muscle and adipose tissue of deer and to investigate their relationship to carcass fatness and tissue fatty acid composition, particularly as venison lipids are reported to be very high saturated.

This research was conducted to evaluate the nutrient content ofAstacus leptodactylusin various populations in the lakes Iznik and Egirdir, as well as in Hirfanlı Dam Lake and Keban Dam Lake, all in Turkey. Crayfish meat yield ranged from a minimum of 11.3% to a maximum of 16.3% of wet weight in specimens from Keban and Iznik, respectively. Meat yield was significantly different, depending on the living environment. The protein content of the meat ofA. leptodactylusranged from 15.4 to 17.5%. The moisture content of crayfish was significantly lower in the high lipid containing Iznik Lake’s crayfish. Crayfish lipids were poor in saturated fatty acids, but rich in PUFA’s and in particular EPA, DHA and ARA. In all groups, the major saturated fatty acids were palmitic acid, stearic acid and myristic acid. Among the omega-6 fatty acid series, a high level of ARA was observed in crayfish meat.EPA may be considered as the major omega-3 fatty acid in crayfish lipids. There was no single fatty acid indicating regional differences in crayfish specimens.

The objective of this study was to characterize and compare the tissue-associated differences in the fatty acid profiles of intramuscular and subcutaneous fat from pasture fed nondescript deshi breed bulls of Bangladesh. The average chemical composition of thelongissimusmuscle was as follows: moisture74.65±0.48%, protein21.55±0.83%, intramuscular fat2.78±0.28%, and ash1.02±0.03%. There was significant evidence that the lipids oflongissimusmuscle from the nondescript deshi bulls had a lower content of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and conjugated linoleic acid (CLA) and a higher content of polyunsaturated fatty acids (PUFA) compared to subcutaneous fat. Intramuscular fat also showed the highest PUFA/SFA and∑n-6/∑n-3fatty acids ratios and total n-3 and n-6 PUFAs compared to subcutaneous tissue depots. Overall findings suggest that the meat from pasture fed nondescript deshi breed can be considered as lean meat and healthy for human consumption.

  Fatty acid levels of two edible and medicinal species: Delonix regia and Tetrapleura tetraptera seeds flour were investigated using standard analytical techniques. Among the saturated fatty acids (SFA), palmitic acid (17.2-49.4%) had the highest concentration in both samples. Oleic acid (19.7-21.0%) was most abundant among the mono-unsaturated fatty acids (MUFA). In both samples, palmitoleic acid recorded 0.00% concentration, whilst margaric acid (0.001-0.060%), lignoceric acid (0.001-0.079%) and arachidonic acid (0.065-0.080%) were found in trace amounts. Both samples were high in total poly-unsaturated fatty acids (PUFA) (26.9-42.7%). MUFA/SFA was less than 1.00 in both samples (0.375-0.584); PUFA/SFA was 1.18 (Delonix regia) and 0.507 (Tetrapleura tetraptera). Total unsaturated fatty acid (TUFA) (63.8%) was higher than total SFA(36.1%) in Delonix regia. In Tetrapleura tetraptera, SFA (53.1%) was more than TUFA (46.8%). 2n-6/3n-3 were high at 59.9 (Delonix regia) and 536 (Tetrapleura tetraptera). The correlation coefficient of the fatty acids was positively high and significant

The aim of this study was to evaluate the fatty acid profile in soybean cultivars from northeastern Brazil, materials developed primarily to achieve a minimum level of oil and protein. The purpose is to serve as to warn about the need to modify fatty acids profiles to enhance both the oil for human consumption and that used in biodiesel production. Results showed the predominance of linoleic acid (average 50.1%) followed by oleic acid (27.9%), palmitic acid (11.97%), linolenic acid (6.68%) and stearic acid (3.38%) in the composition of fatty acids. Such condition makes soybean oil less competitive for both human consumption (for its high content of saturated fatty acids) and the biodiesel industry (problems with oxidative stability and flow in the cold). Considerations are also made on conventional and modern techniques to overcome these drawbacks.

Enriching chicken meat with the very long chain n-3 polyunsaturated fatty acids (VLC n-3 PUFA) 20:5 (EPA) and 22:6 (DHA) is a possible means of increasing the human consumption of these essential fatty acids as current levels of intake of these fatty acids are extremely low. However, a potential drawback of increasing the VLC n-3 PUFA content of chicken meat is that the oxidative stability of the meat is reduced. PUFA are more oxidatively unstable than monounsaturated or saturated fatty acids, and the aldehydes produced by the n-3 PUFA during autoxidation have a lower taste threshold, and are much more unpalatable, than the aldehydes associated with autoxidation of the n-6 series of PUFA. The objective of this study was to determine what relationship there was between the fatty acid profiles of chicken meat that had been enriched (by dietary means) with VLC n-3 PUFA and the volatile aldehydes that were produced by the meat after it had been cooked.

Crassostrea Rhizophorae

Mangrove oysters, Crassostrea rhizophorae were collected at the mangrove of "Barra de Guaratiba" district, Rio de Janeiro, Brazil, with the aim to determine the proximate composition and fatty acid content. Along the year seasons no statistical (P>0.05) difference was observed in the values of moisture, crude protein, crude lipid and ash. They were 82.0%; 9.7%; 1.7%; 3.2%, in average, respectively. However, glycogen was significantly (P<0.05) higher in spring (4.4%) and winter (4.2%) samples, than in summer (2.7%) and autumn (2.9%), samples. Saturated fatty acids and polyunsaturated fatty acids were respectively, the most important fatty acids in oysters, with the palmitic acid (16:0), being the major fatty acid. This study, demonstrated that this species was characterized by low fat content (< 2.0%) and also being a good source of eicosapentaenoic (20:5n-3, EPA) and docosahexaenoic (22:6n-3, DHA) fatty acids. Therefore, C. rhizophorae, in terms of lipid and fatty acids, could be recommended for human consumption.

Decreasing saturated fatty acids and increasing monounsaturated fatty acids are desirable to improve oil for food. Seed oil content and fatty acid composition are affected by genotype and environment. Therefore, we systematically analyzed the agronomic traits and fatty acid metabolic profiling of Brassica napus (B. napus) seeds at different developmental stages in high level of oleic acid (HOA), medium level of oleic acid (MOA), and low level of oleic acid (LOA) B. napus cultivars, both sown in winter and summer. The results showed that all winter-sown cultivars produced 20% more seed yield than the summer-sown crop. The longer growing period of winter-sown B. napus resulted in higher biomass production. However, the fatty acid metabolism of individual cultivars was different between winter-sown rape (WAT) and summer-sown rape (SAT). The absolute fatty acid content of LOA and MOA cultivars in WAT were significantly higher than that in SAT, but that of HOA was opposite. Importantly, the levels of monounsaturated fatty acids (18:1; 20:1) in SAT were far more than those in WAT. These data indicate the quality of oil from the HOA in SAT is more suitable for human consumption than that in WAT.

We compared nutrient compositions of honey bee (Apis mellifera) drones of different developmental stages from two different populations—the Italian honey bee reared in Korea and Buckfast bees from Denmark. Analyses included amino acid, fatty acid, and mineral content as well as evaluations of antioxidant properties and haemolysis activities. The compositions of total amino acids, and thus protein content of the insects, increased with development. A similar trend was observed for minerals presumably due to the consumption of food in the adult stage. In contrast, total fatty acid amounts decreased with development. Altogether, seventeen amino acids, including all the essential ones, except tryptophan, were determined. Saturated fatty acids dominated over monounsaturated fatty acids in the pupae, but the reverse held true for the adults. Drones were found to be rich in minerals and the particularly high iron as well as K/Na ratio was indicative of the nutritional value of these insects. Among the three developmental stages, adult Buckfast drones exhibited the highest antioxidant activity. Bearing in mind the overall high nutritional value, i.e., high amino acids, minerals and less fatty acids, late pupae and adult drones can be useful for human consumption while the larvae or early pupal stage can be recommended as feed. However, owing to their relatively high haemolysis activity, we advocate processing prior to the consumption of these insects.

Seeds of sweet oranges (Citrus sinensis) were analyzed for oil and fatty acid composition. The crude oil was extracted by the use of soxhlet extraction. The results showed that oil content is as high as 71 %. The physico-chemical assessment gave the following results: refractive index (1.457), peroxide value (4.12 meq/kg) and iodine value (34.06 Wijs). The ATR-IR spectrum of oil showed prominent bands at 3008.6, 2921.73, 2852.7, 1742.86, 1709.23, 1460, 1167.66, 1117.39 and 1051.16 cm-1 that identified fatty acid composition. The percentage compositions of various classes of fatty acids present in the oil were polyunsaturated fatty acids (PUFAs, 39.82 %), monounsaturated fatty acids (MUFAs, 57.08 %) and saturated fatty acids (SFAs, 3.09 %). The oil has linoleic acid (18:2, n-6) as the only PUFA and the second highest fatty acid composition (25.63 %). Palmitoleic acid is the highest MUFA (56.30 %) as well as the highest fatty acid composition while capric acid (C10:0) is the lowest fatty acid (0.02 %). These results and in addition to the low compositions of erucic acid, behenic acid and lignoceric acid indicated that the seed oil of sweet orange is possible suitable for both human consumption and industrial purposes.
