Creating dietary margarines using biologically valuable substances is the purpose of the work. According to the results of the experiments, it was found that the use of soybean oil, edible vegetable phospholipids and a Jerusalem artichoke extract in the margarine, allowed reducing the amount of fat and enriching the margarine with omega-3 and omega-6 fatty acids, dietary fibre, inulin and other water-soluble substances. Based on these studies prepared margarine enriched inulin and essential fatty acids, which provide not only a preventive property of the finished product, but also high flavor indicators, as well as, original and attractive appearance.

Omega-3 fatty acids (Alpha-linolenic acid) and omega-6 fatty acids (Linoleic acid) are a group of essential fatty acids. Essential fatty acids are fatty acids that cannot be synthesized by the body so that must be supplied from the diet. One of the sources of essential fatty acids is derived from fish oil. This study aims to determine the effect of Crude Fish Oil (CFO) in the feed to EPA and DHA content in penaeid shrimp meat. The research method used was a completely randomized design. The treatments used are the varying content of Crude Fish Oil (CFO), which are P0 (0%), P1 (2%), P2 (4%), P3 (6%), and P4 (8%). The results of the study showed significant differences (p <0.05) on the content of EPA and DHA in penaeid shrimp meat. The highest content of EPA and DHA found in P4 treatment (8%) and the lowest at P0 treatment (0%). The use of CFO in penaeid shrimp feed need further study related to the growth of shrimps and prawns reproductive cycle to increase the productivity of penaeid shrimp. CFO on feed should be used at a dose of 6%.

The use of the saline microalgae,Dunaliella salina, Sinecosyfissp., andChroomonassp., was explored as an alternative source for the production of fatty acids using fertilizer and glycerol as culture media. The nutrient medium used contained “Nutrifoliar,” a commercial fertilizer, and/or glycerol, in natural sea water. The microalgae were placed in cultures with different conditions. The parameters that favored the largest production of fatty acids were 24 hours of agitation and illumination, 1620 L/day of air supply, 2.25 L of air/min, and a temperature of 32°C using “Nutrifoliar” as the culture media. Results indicated that, from 3 g of microalgae in wet base ofChroomonassp., 54.43 mg of oil was produced. The chromatographic characterization of oil obtained revealed the presence of essential fatty acids such as 9,12,15-octadecatrienoic acid (omega-3) and 4,7,10-hexadecatrienoic acid (omega-6) from the speciesDunaliella salina.On the other hand, 9,12-octadecadienoic acid (omega-6) and cis-11-eicosenoic acid (omega-9) were identified from the speciesChroomonassp. The temperature variations played an important role in the velocity of growth or the production of the algae biomass, the amount of oil, and the ability to produce fatty acids.

The article analyzes the fatty acid composition of the frozen iwashi lipids of different shelf lives. It is established that the total amount of essential fatty acids omega-3 and omega-6 in iwashi’s fat reaches almost 90% of all polyunsaturated fatty acids and remains practically unchanged for 12 months of fish cold storage. It is shown that products from iwashi contain a significant amount of essential fatty acids, indispensable for the human body, which can be used to optimize the population nutrition and satisfy the physiological needs in eicosopentaenoic and docosahexaenoic fatty acids.

Crop Variety

SAU Perilla-1 (Golden perilla BD) is a newly edible oil seed crop variety introduced by Sher-e-Bangla Agricultural University in Bangladesh. Its seed oil is a rich source of unsaturated fatty acid (91%), of which more than 50% is α-linolenic acid (type of omega-3 fatty acid). The estimated ratio of saturated, monounsaturated and polyunsaturated fatty acids was found 1: 2.26: 8.95. Moreover, the α-linolenic acid was detected (50.52%) as the most dominating polyunsaturated fatty acid, which was 4-four times higher than monounsaturated fatty acids in the oil of the crop variety. Fatty acid analysis of oil revealed a ratio (1:2.22) of Omega 6 to Omega 3 fatty acids, which lies within a healthy range as documented by the global scientific community. Compared to other plant seed oils, SAU Perilla-1 oil consists of Linoleic acid (Omega 6 fatty acid, 22.71%) – a component associated with obesity, which is far below the regular oils from soybean, sunflower and corn. Therefore, our findings indicated that SAU Perilla-1 seed is one of the best edible sources of plant oils rich in essential fatty acids conducive to human health.

AbstractThe fatty acid profiles of the three lipid fractions, neutral lipids (NL), free fatty acids and polar lipids (PL), from the macroalgae Palmaria palmata (wild), Alaria esculenta (cultivated) and Saccharina latissima (cultivated) were studied in light of dietary important fatty acids. Blade and stipe from the macroalgae were collected at the end of the growth season (May/June) at Frøya (Trøndelag, Norway). A total of 51 fatty acids were identified in the algae, including several fatty acids novel to one or more of the algae. The NL and PL fractions of P. palmata were the most promising from a health perspective, due to a high content of eicosapentaenoic acid (10.1 ± 0.5% and 6.6 ± 0.1%, respectively) and no trans-fatty acids. In addition, these fractions had very low omega-6/omega-3 ratios (< 0.1) and can therefore be beneficial for balancing the omega-6/omega-3 ratio in the diet. The NL fraction of A. esculenta had the highest content of monounsaturated- and polyunsaturated fatty acids (20.9 ± 1.4 and 21.8 ± 1.9% of alga, respectively), as well as the highest content of the two essential fatty acids, linoleic acid (5.3 ± 0.4% of alga) and alpha-linolenic acid (2.4 ± 0.2% of alga). Indices related to risk factors for coronary heart disease were most favourable in the NL fraction of S. latissima and the NL and PL fractions of A. esculenta.

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.
