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.

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.

The objective of this study was to determine the chemical characteristics of sliced beef dendeng and ground beef dendeng circulating in Malang city, i.e., fat content, fatty acid profile, moisture content, water activity and total calories. The quantitative descriptive analysis was used as research design. The data obtained were analyzed statistically by using the calculation formula according to the method used. The sliced dendeng and ground dendeng circulating in Malang city was used as sample. Beef dendeng circulating in Malang city had a fat content of 3.43-6.77%, moisture content of 19.56-27.50%, water activity of 0.69-0.84, and total calories of 93.38-136.77 kcal. The sliced beef dendeng with the best chemical characteristics (closed to national standard) was tested for fatty acid profile analysis. About 37 fatty acids were identified, consisting of 19 saturated fatty acids and 18 unsaturated fatty acids. It was concluded that both types of beef dendeng circulating in Malang city had different fat content, fatty acid profile, moisture content, water activity and total calories. These differences were influenced by raw materials, spices and processing used.

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.

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.

The objective of this study to compare the fatty acids composition in cooking oil from repeated frying without added turmeric extract and added. The research design is testing the composition of fatty acids in repeated cooking oil using two types of treatment, namely cooking oil from frying without adding turmeric extract and cooking oil from frying with 0.03% turmeric extract added with 10 times frying repeat because it is suspected that repeated frying will increase the composition of fatty acids in cooking oil. The analysis of fatty acids was conducted using gas chromatography. Based on these results that the fatty acid components were produced of saturated fatty acids, namely lauric acid, myristic acid, palmitic acid, and stearic acid, whereas unsaturated fatty acids also detected such as elaidic acid, oleic acid, linoleic acid, cis-11-eicosadienoic acid, linolenic acid, and cis-11,14-eicosadienoic acid. The highest saturated fatty acid content in cooking oil before frying is palmitic acid (30.88%), whereas unsaturated fatty acid was oleic acid (35.86%). The highest content of saturated fatty acids in cooking oil has been added turmeric extract before frying is palmitic acid (28.5%), while unsaturated fatty acid of oleic acid was 32.97%.

Fluid milk and its derivatives are important dietary ingredients that contribute to daily nutrient intake of the modern Homo sapiens. To produce milk that is healthier for human consumption, the present study evaluated the effect of adding soybean oil and linseed oil in the diet of lactating cows. The fatty acid profile of milk, milk composition, and the blood parameters of cows were evaluated. Eighteen Holstein cows were distributed in a replicated Latin square design and distributed according to the following treatments: 1) Control (CC): traditional dairy cow diet, without addition of oil; 2) Soybean oil (SO): 2.5% addition of soybean oil to the traditional diet, as a source of omega-6; 3) Linseed oil (LO): 2.5% addition of linseed oil in the diet as a source of omega-3. Milk production was not affected, but oil supplementation decreased feed intake by 1.93 kg/cow/day. The milk fat percentage was significantly lower when cows were supplemented with vegetable oil (3.37, 2.75 and 2.89% for CC, SO and LO, respectively). However, both soybean and linseed oils decreased the concentration of saturated fatty acids (66.89, 56.52 and 56.60 g/100g for CC, SO and LO respectively), increased the amount of unsaturated fatty acids in milk (33.05, 43.39, and 43.35 g/100g for CC, SO and LO respectively) and decreased the ratio between saturated/unsaturated fatty acids (2.12, 1.34, and 1.36 for CC, SO and LO respectively). Furthermore, SO and LO increased significantly the concentration of monounsaturated fatty acids (29.58, 39.55 and 39.47 g/100g for CC, SO and LO respectively), though it did not significantly alter the level of polyunsaturated fatty acids in milk fat (3.57, 3.93 and 3.98 g/100g for CC, SO and LO respectively). Supplementation with LO enhanced the concentration of omega-3 fatty acids on milk (0.32, 0.36, and 1.02 for CC, SO and LO respectively). Blood variables aspartate aminotransferase, gamma glutamyl transferase, urea, albumin, creatinine and total proteins were not altered. On the other hand, total cholesterol, HDL and LDL were greater in the group supplemented with vegetable oils. Supplementation with vegetable oils reduced the dry matter intake of cows, the fat content of milk, and improved saturated/unsaturated fatty acid ratio of milk fat. Compared to the SO treatment, animals fed LO produced milk with greater content of omega-3, and a more desirable omega-6/omega-3 ratio on a human nutrition perspective. Thus, the inclusion of SO and LO in the diet of lactating dairy cows makes the milk fatty acid profile nutritionally healthier for the human consumption.

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.
