Variation among F3 seeds from a single head for linoleic acid content was high (50.0-72.7%) and appeared unrelated to seed position. Fatty acid content of seeds within self-pollinated heads was not affected by unfilled, adjacent seeds. Thus single seed selections for linoleic acid content should not be biased. No general relationship between fatty acid level and seed position was evident from, analyses of bulk samples except that palmitic acid content of seeds from the upper half of heads (7.4%) was higher than from the lower half (6.5%). This may be related to the negative correlation (r = -0.45) between palmitic acid content and seed size. Fatty acid content and weight of seeds from the lower half of heads were less variable than from the upper half.

In 1990ys antiatherogen, antioxidant and anticarcinogen effect of conjugated linolacids (CLA) was detected. From this reasons, our aims in this study were producing pork rich in CLA and studying the change of fatty acid composition of the produced pork cooked different kind of fats. For frying palm and sunflower oil and swine fat were used. Thigh was cutted for 100 g pieces. Meat pieces were fried at 160 °C for 1 and 8 minutes. Estimation of frying data it was determined that higher (0.13%) CLA content of pork was spoiled (60-70%) except in case of swine fat cooking,because it is extremly sensitive for oxidation and heating. Swine fat has higher (0.09%) CLA content than plant oil, protecting the meat’s original CLA content. Cooking in swine fat did not have significant effect on fatty acid composition of meat. Low level of palmitic acid contect of sunflower oil (6.40%) decreased for half part of palmitic acid content of pork (24.13%) and it produced cooked meat with decreased oil acid content. Contrary of above, linoleic acid content of fried meat was increased in different folds as compared to crude pork. If it was fried in sunflower oil with high level linoleic acid increased (51.52%) the linoleic acid content in fried pork. The linoleic acid content of the high level CLA pork increased four times (48.59%) to the crude meat (16.59% and 12.32%). The high palmitic acid content of palm fat (41.54%) increased by 60% the palmitic acid content in fried pork, low stearic acid (4.44%) and linoleic acid content (10.56%) decreased the stearic and linoleic acid content of crude meat.

Abstract Twelve powdered and 13 liquid infant formulas were analyzed by using an extension of AOAC Official Method 996.01 for fat analysis in cereal products. Samples were hydrolyzed with 8N HCl and extracted with ethyl and petroleum ethers. Fatty acid methyl esters were prepared by refluxing the mixed ether extracts with methanolic sodium hydroxide in the presence of 14% boron trifluoride in methanol. The extracts were analyzed by gas chromatography. In powdered formulas, saturated fatty acid (SFA) content (mean ± SD; n = 12) was 41.05 ± 3.94%, monounsaturated fatty acid (MUFA) content was 36.97 ± 3.38% polyunsaturated fatty acid (PUFA) content was 20.07 ± 3.08%, and total trans fatty acid content was 1.30 ± 1.27%. In liquid formulas, SFA content (mean ± SD; n = 13) was 42.29 ± 2.98%, MUFA content was 36.05 ± 2.47%, PUFA content was 20.65 ± 2.40%, and total trans fatty acid content was 0.88 ± 0.54%. Total fat content in powdered formulas ranged from 4.4 to 5.5 g/100 kcal and linoleic acid content ranged from 868 to 1166 mg/100 kcal. In liquid formulas, total fat content ranged from 4.1 to 5.1 g/100 kcal and linoleic acid content ranged from 820 to 1100 mg/100 kcal. There were no significant differences between powdered and liquid infant formulas in concentrations of total fat, SFA, MUFA, PUFA, or trans fatty acids.

Data from advanced breeding experiments between 1985 and 1994 were used to determine the effects of region, year and environment on the quality of canola grown across Victoria. Estimates from these unbalanced data were made using residual maximum likelihood. Environmental effects were large relative to cultivar effects for oil and protein content, while the reverse occurred for glucosinolate content. High oil contents (and low seed protein contents) were correlated with cooler spring temperatures and higher spring rainfall. Oil contents were lowest, on average, in canola grown in dry years, or from the hotter regions, such as the Mallee, and were highest in canola from the cooler, wetter regions, such as south-western and north-eastern Victoria. Fatty acid composition varied with year and region. Means for saturated fatty acid content averaged 6.4 0.1%. The oleic acid content averaged 60.3 0.4% and was higher in canola grown in central Victoria and the Wimmera, and in most years, in north-eastern Victoria compared with other regions. Low temperatures and low rainfall reduced oleic acid content. Linoleic acid content averaged 19.7 0.3% and linolenic acid averaged 10.4 0.3%, with the content of these fatty acids negatively correlated with the content of oleic acid. Erucic acid levels were below 0.6% in all regions.

The design of the study was an experimental with the degree of subsititution of coconut water as treatments.

Avocado juice product with 75% avocado substitution and 25% coconut water (F1) was a best formula determined by the hedonic test. This formula contained 68,48% (%w/w) water, 3,12% (%w/w) ash content, 4,45% (%w/w) fat content, 1,76% (%w/w) protein content, 21,07% (%w/w) carbohydrate content, 2163,8 (mg/kg) potassium content, 9,20% (%w/w) linoleic acid content, 1,11% (%w/w) linolenic acid content and 42,4% (%w/w) of total unsaturated fatty acid. This product could potentially reduce and prevent hypertension, because in one serving size (200cc) contain 432,76 mg of potassium (claim source of potassium). </em><em></em></p>

Effect Of Feeding

The composition of fatty acids in food products is a significant factor in human health. Feeding can significantly influence the composition of fatty acids in the animal fat. We analysed the effect of feeding high CLA-content (conjugated linoleic acid) feed on the composition of fatty acids in pork. The animals were grouped according to the following: Group 1) feeding experimental, ghee-mixed feed for 76 days, Group 2) feeding the same feed, but only for 33 days, Group 3) feeding sunflower-oil-mixed feed for 76 days. Ghee contains CLA in high amount. The aim of our experiment is to analyse how the high CLA content influences the fatty acid content of pork. In the end of the fattening experiment the animals were slaughtered, then samples were taken from the loin, ham, abdomen and backfat from 10 animals from each group and analysed the fatty acid content. We found significant differences between the average fatty acid content of the samples. As an effect of feeding ghee-enriched feed, the CLA content significantly increased, compared to the control group. However, the linoleic acid and the arachidonic acid content were lower, and the proportion of fatty acids was also lower when feeding control feed.

Abstract Background: Fatty acid composition and content affect rapeseed oil quality. Fatty acid synthesis-related genes in rapeseed have been studied globally by researchers. Nevertheless, rapeseed oil is mainly composed of seven different fatty acids, and each fatty acid was regulated by different genes, furthermore different fatty acid contents affect each other, which needs continuous and in-depth research to obtain more clear results.Results: In this paper, broad-scale miRNA expression profiles were constructed and 21 differentially expressed miRNAs were detected. GO enrichment analysis showed that most up-regulated proteins were involved in transcription factor activity and catalytic activity. KEGG pathway enrichment analysis indicated that 20 pathways involving 36 target genes were enriched, of which the bna00592 pathway may be involved in fatty acid metabolism. The results were verified using a Quantitative Real-time PCR (RT-PCR) analysis, and it was found that the target gene of bna-miR156b>c>g was the OPR (12-oxo-phytodienoic acid reductase). Four copies of OPR gene were found, and the over-expression vectors (pCAMBIA1300-35s-OPR and pCAMBIA1300-RNAi-OPR) were constructed to verify their functions. In T1 and T2 plants, OPR-OE (OPR Over-Expression strain) significantly increased linoleic acid content (T1 12.56%, T2 7.185%) and OPRi (OPRi RNA-interference strain) decreased linoleic acid content (T1 5.98%, T2 0.86%).Conclusions: This is the first study to provide four copies of the OPR gene that regulates LA metabolism, can be used for the molecular mechanism of LA and optimizing fatty acid profiles in oilseed for breeding programs.
