Major Carps

Abstract Indian major carps are the widely consumed fish species of Pakistan, being a cheap source of proteins and unsaturated fatty acids, they are good for cardiovascular health. Water pollution due to discharge of untreated industrial waste water into water bodies contaminates this precious source of nutrients. The present study therefore, was aimed to assess deterioration of fatty acid profile of three Indian major carp species due to different concentrations of industrial wastes. The water samples were collected from the river Chenab at the site where it receives industrial wastewater via Chakbandi drain. After exposure to 1.5%, 3.0%, and 4.5% dilutions of collected water in different aquaria it was observed that proportion of unsaturated fatty acids in selected fish species were decreased significantly as the intensity of the dose increased (P < 0.05). Conversely the level of saturated fatty acids increased with the increasing dose of treatment (P < 0.05). These findings suggest that untreated wastewater not only deteriorate the fatty acid profile of aquatic animals but also these toxic substances can reach human body through fish meat and pose further health hazards. Therefore, it is highly recommended that industrial effluents should be treated before they are dumped into water bodies.

Hygienic Quality

The objective of this work was to investigate the fatty acid composition and assess hygienic quality of the Algerian camel milk from Targui breed, then to compare obtained results with cow milk in local rearing conditions. Sampling was performed over three months at a rate of one sample per month. The physicochemical analyzes carried out revealed that the Targui camel milk had averages values of 6.33 ± 0.15 for the pH, acidity equal to 18.50 ± 0.02 °D, and 1030.40 ± 1.08 for density. The total dry extract and the fat levels were lower than those of cow milk. In addition, results of fatty acid profile analysis from camel milk revealed a relatively low level of saturated fatty acids (SFAs) compared to cow milk, palmitic acid (C16:0) being the predominant fatty acid in both milks. The content of unsaturated fatty acids (UFAs) was significantly higher in camel milk fat compared with cow milk, with higher total monounsaturated fatty acids (MUFAs) rate in camel milk. Oleic acid (C18:1 n9) was in the same proportions, and the most abundant unsaturated fatty acid in both species. However, no significantly difference was observed between PUFAs levels of camel and cow milk. Linoleic acid (C18:2 n6) was the most represented polyunsaturated fatty acid in both milks with similar proportions. In contrast, the content of α-linolenic acid (C18:3 n3) was significantly (p<0.001) higher in cow milk than in camel one.

The Impact

Abstract The aim of the study was to determine the impact pike fishing season (before spawning in fall (group A) and after spawning in spring (group B)) had on the slaughter yield and fillet fatty acid profile. The slaughter yield of fillets with skin and skinned fillets from the group B fish was significantly lower (by approximately 7.5% of body weight). The fatty acid profile of the fish meat from the groups examined differed significantly. The fillets of pike caught before spawning were dominated by unsaturated fatty acids (UFA), while those from fish caught after spawning had mainly saturated fatty acids (SFA). The share of polyunsaturated fatty acids (PUFA) in the fillets of fish that had spawned was sixfold lower, and the n-3 PUFA differences were nearly ninefold. The content of eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids in fillets of fish that had spawned was ninefold lower than in those that had not yet done so. Consequently, the ratio of n-3 PUFA/n-6 PUFA in pike from group A was over three times higher than that in the fish that had spawned (2.61 vs 0.82). Fillets from pike that have spawned are a significantly poorer source of valuable fatty acids for consumers.

Sheep Milk

Background: Sheep milk production is becoming an important alternative in the agricultural sector. It is used principally to produce fine cheeses, yogurts, and ice creams, and these produced from sheep’s milk are beneficial to human health. Previous study with palm oil shows increase in fat levels in sheep’s milk. Our hypothesis for increased fat in milk is that palm oil increases lipid metabolism as well as tissue reserves. Sheep consuming this palm oil will have a change in the fatty acid profile of milk, increasing levels of unsaturated fatty acids. Therefore, the aim of this study was to determine the levels of cholesterol and triglycerides, as well as fatty acid profile of milk these ewes fed of palm oil.Materials, Methods & Results: Thirty-six lactating sheep were divided in four groups (n = 9), with each group receiving various concentrations of palm oil in diet (0%, 2%, 4%, and 6% which corresponds to T 0, 2, 4 and 6, respectively). The diets in each treatment were isoproteic and isoenergetic. The experiment lasted 120 days, and blood and milk samples were collected on days 60 and 12 of the experiment. Blood was collected for seric analysis of lipid metabolism. Was collected milk samples and analyzed the content of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA). An increase (P < 0.05) in triglyceride and coleterol levels in the serum of the animals that received the highest concentrations of palm oil in the diet (T4 and T6). The centesimal composition of fat, lactose, and protein in milk was not different at days 60 and 120 (P > 0.05) between groups, but numerically the animals in T4 and T6 had higher percentage of fat in milk. A decrease in milk SFA levels was observed on day 120 at T6. There was a significant reduction in caproic acid, caprylic acid, hendecanoic acid, lauric acid, and pentadecyl acid. The levels of palmitic acid (C16:0) increased when compared with the control group. Also at 150 days, it was observed a reduction in the percentage of area capric acid and myristic acid in animals that had higher doses of calcium salts in the diet, different from stearic acid, which increased. A variability in MUFA levels was observed during the evaluated periods, i.e. heptadecenoic acid decreased on days 60 and 120 for animals of T6; an increased content of elaidic acid was observed on day 60, and levels of vaccenic acid decreased on day 120 at 6% palm oil. A decrease in PUFA levels was observed on day 60 at T6, specifically a significant reduction in alpha-linolenic and arachidonic acid, as well as levels of conjugated linoleic acid 1 decreased on day 120 for animals supplemented with 6% of palm oil.Discussion: The addition of plama oil in the diet of dairy sheep increased seric levels of triglycerides and cholesterol, as well as positively altered the composition of fatty acids in milk, making a product healthier to the consumer. This study showed that the addition of 2% and 4% palm oil in the feed of dairy sheep promoted a decrease in several SFAs associated with coronoary heart disease after 60 days of treatment. On the other hand, the addition of 6% palm oil promoted an increase of total SFA levels after 60 days of treatment, while decreaseing total PUFA levels. This can be considered harmful to consumers, since several SFA are associated with coronary heart diseases, and several PUFA are linked with reductions in inflammation, stroke, oxidative stress and hepatic disorders. In summary, the consumption of sheep milk who received the diets with 2% and 4% of palm oil can exert beneficial effects for consumers, and may be an option for farmers to increase the milk yield of sheep, and to reduce the profile of saturated fatty acids in milk.

The seed oil of “batuan” [Garcinia binucao (Blco.) Choisy] fruit, an indigenous, lesser known, and with promising economic potential, was characterized to evaluate its quality and potential for product development. Using standard AOAC methods, thin layer chromatography and gas chromatography, the physicochemical properties, lipid and fatty acid profile were determined. Oil yield from “batuan” seeds was high. The extracted oil was yellowish white, soft solid at room temperature. Iodine value, acid value, and peroxide value of the seed oil were low while saponification value was high. Lipid presents in “batuan” seed oil is mostly triglycerides while diglycerides are in low amount. Unsaponifiable matter (<1.0%) was abundant in sterol, squalene and beta-carotene, and minor amount of Vit. A palmitate, and-tocopherols. Stearic (C18:0), oleic (C18:1), and palmitic (C16:0) acids were the major fatty acids while arachidic, linoleic and linolenic acids constitute the minor components. “Batuan” seed oil contained more saturated fatty acids than the unsaturated fatty acids which could be responsible for its being a soft solid at room temperature. Results of this study show that “batuan” seed oil is of good quality and could be a potential source of valuable oil for food and other industrial applications.

Canola oil is an important source of oleic acid, in addition to being an accessible source for its use in the production of pigs’ diets. Oleic acid in turn is a type of unsaturated fatty acid that in pork is beneficial for human health. Therefore, this study was conducted to describe the fatty acid profile in brain and liver tissues from pigs supplemented with canola oil for 98 days, during the growth and finishing phases. For the analysis was used eighteen male pigs that had free access to feed and water throughout the experimental period.  Dietary treatment consisted of corn-soybean meal growing-finishing diets supplemented with 3% fat from canola oil (CO). To obtain the fatty acid profile, the lipids from each tissue were cold extracted using the adapted method from Bligh and Dyer, methylated, and posteriorly injected in a gas chromatograph to obtain the fatty acid profile of the tissue. In both tissues there was a greater abundance of saturated fatty acids (stearic acid). The most abundant monounsaturated fatty acid was the oleic acid. Regarding polyunsaturated fatty acids, in the liver the most abundant was linoleic acid and in the brain docosahexaenoic acid. In summary, animals' diet influences the fatty acid profile in different tissues. Such modifications can increase unsaturated fatty acids concentration in relation to saturated, making pork healthier for human consumption.

This study aimed at evaluating the effect of roasting conditions on some physicochemical and nutritional properties of cashew nut lipid fractions at different temperature (100–160ᵒC) and time (20–60 min). Raw and roasted cashew nuts were also analyzed for their composition in fatty acid by GC-FID. Physicochemical properties of the oil showed that the oil yield of roasted cashew nut oil (56.67-31.67%) was significantly higher compared to unroasted oil (47.43%). Also, cashew nut oil with mean values revealed that acid (12-0.86 mg KOH/g of oil); saponification value (138.10-169.06 mgKOH/g of oil), iodine value (55.50-36.19 mg of I/100g of oil); TBA(0.012-0.18mg); p-anisidine value (0.55-0.66); peroxide value (7.26-3.05 meq/kg) and free fatty acid (1.07-1.50 % oleic acid) which indicated that cashew nut oil is edible, non-drying and may not be suitable for soap making. Results of GC-FID analysis of the ethyl esters of saturated and unsaturated fatty acid of raw and roasted cashew nut showed that unsaturated fatty acids represented 60.57% for unroasted samples with roasted samples (79.67–83.67%) while saturated fatty acids recorded (16.11–37.65%). The fatty acid composition of the oils shows the presence of four main fatty acids: palmitic (9.25–29.50%); stearic (4.4–9.34%); oleic (34.75–65.60%); and linoleic (1.35–20.66%) with high oleic to linoleic ratio associated with high oil stability. The order of increase is oleic &gt; linoleic &gt; palmitic &gt; stearic in all the samples irrespective of roasting conditions. The result showed that minor changes occur in the fatty acids composition as the roasting temperature and time increased. It was concluded that the heat treatment used does not significantly affect the fatty acid profile content of cashew nuts preserving its antioxidant activity along with other bioactive compounds contained therein.
