OBJECTIVE Long-chain n-3 fatty acid intake in Colombia is low because fish consumption is limited. Vegetable oils with high n-3 fatty acid content are recommended, but their concentrations of trans fats were high in previous studies. Thus, regular monitoring of the fatty acid composition of vegetable oils is required. Our objective was to quantify the fatty acid composition in commercially avai...

To study oil contents and fatty acid composition among the samples of Jatropha curcas L. seeds were collected from Dehradun, Uttarakhand. Soxhlet extraction method and gas chromatography (GC) were employed to determine the oil contents of Jatropha seeds and the fatty acid composition of Jatropha oil. The seed oil contents (dry basis) was 46.27% .Physicochemical properties shows acid value (36.4...

this study was conducted to evaluate the effect of sowing date on morphology, yield parameters, as well as oil percentage and fatty acids composition of castor bean. the experiment was carried out at research farm of tarbiatmodaresuniversity, in randomized complete blocks design with three replications during 2010. plants were grown at six sowing dates of 5th april, 20th april, 5th may, 20th ma...

Conjugated Linoleic Acid (CLA), Glycerol (G) and sunflower oil blends with varying concentration were subjected to enzymatic esterification using a 1, 3- specific immobilized lipase. CLA was used as acyl due to its purported health benefits. The transesterified lipids were evaluated for free fatty acids (FFA) and composition of fatty acids by gas chromatography. Lipozyme RM IM is preferred for ...

In this project, different nettle plants from north regions of Iran including Tonekabon, Amol and Gorgan were collected. The oil was extracted using soxhlet extraction apparatus and was subjected to series of physical and chemical tests and determinations consisting of refractive index, melting point, smoke point, nonsaponifiable matter, Iodine value, saponification value, peroxide value, totox...

The fatty acid composition of a thermophilic Bacillus sp. was altered by the addition of isobutyrate, isovalerate, a-methylbutyrate, leucine, and isoleucine to the growth medium. With isobutyrate, 81% of the fatty acids had 16 carbon atoms and 79% were iso-fatty acids with an even number of carbon atoms. With leucine, 58% of the fatty acids had 15 carbon atoms and 86% were iso-fatty acids with ...

Pistachio nut has high nutritional value. The fat and protein are the common part of pistachio. Major part (about 88%) of the fat content of pistachio includes unsaturated fatty acids. Unsaturated fatty acids are known to have positive effects on human health like preventing to heart diseases. This research has evaluated protein, fat and fatty acids content of some commercial pistachio cultivar...

Data on the normal distribution of fatty acids in the cholesterol ester fraction of rat plasma and liver and on factors which may influence their distribution are extremely limited at the present time. The information available has been obtained by alkali isomerization and silicic acid and paper chromatography techniques. These methods do not provide an adequate identification and estimation of...

One-hundred-forty-four male Angus calves were utilized to assess the relationship of bulls and steers adipose tissue fatty acid composition for various age groups. Animals were further grouped so as to compare the effects that high or low energy diets have on the tissue components. All animals were slaughtered upon reaching their respective age group and a detailed carcassevaluation performed. ...
