in this study,oil was extracted from the liver and visceral fat of patin (pangasianodon hypophthalmus) and refined. the yield of oil after refining was 49.98%. the major yield loss (34.20%) happened during the degumming procedure. fatty acids found in the crude and refined oil were c12:0, c14:0, c14:1, c16:0, c16:1, c18:0, c18:1, c18:2, c18:3, c18:4, c20:0, c20:1, c20:4, c20:5, and c22:6. the d...

diet as a part of lifestyle plays a pivotal role in the development of metabolic syndrome and its consequences. fatty acid composition as a part of dietary intake affects blood fatty acid concentrations, insulin sensitivity and different metabolic pathways associated with the occurrence and consequences of the metabolic syndrome. the aim of this review is to evaluate the effects of dietary fatt...

pollen grains of five olive cultivars (olea europaea l .) were examined, using scanning electron microscopy (sem) for identification purposes. four measurments, polar axis (p), equatorial diameter (e), p/e ratio and exine patterns were made. forty pollen grains of each cultivar were viewed before finally selecting a representative pollen grain. polar diameter ranged between 22.76 μm for the...

To study the effect of salicylic acid (SA) on the amount and quality of oil in different regions of sunflower inflorescence, a factorial experiment was conducted based on randomized complete block design with 3 replications at the University of Mohaghegh Ardabili, Ardabil, Iran. Salicylic acid at concentrations of 0, 0.1, and 0.2 g L-1 were sprayed on whole plant at 3 stages (twice before flowe...

The aim of the present work was to assess the influence of dietary lipid source on fatty acid phospholipid profiles and on lipid mobilization. Forty male Wistar rats were divided into four groups and fed on high-fat diets which provided olive oil, sunflower oil, palm oil or beef tallow. All rats received the same amount of energy to avoid hyperphagia and differences in energy intake among group...

the present study was conducted to determine the relative contribution of initial quality and compositional parameters to the rate of changes (rctpc) in the content of total polar compounds (tpc), which is considered to be one of the most reliable indicators of heated oils quality, of olive oil during continuous heating at 180 ºc. the ratio between monounsaturated and polyunsaturated fatty acid...

Discordances exist in epidemiological studies regarding the association between the intake of nutrients and death and disease. We evaluated the social and health profile of persons who consumed olive oil in a prospective population cohort investigation (Pizarra study) with a 6-year follow-up. A food frequency questionnaire and a 7 d quantitative questionnaire were administered to 538 persons. T...

A total of 24 miniature swine (Sus scrofa) were fed with two diets of 9% fat content, differing only in the quality of the fat source (sunflower oil and olive oil). Two groups of animals were fed for a 12-week period, and the other two groups were fed for a 50-week period. After the two experimental periods, the influence of the dietary fat on serum lipids and protein and fatty acid composition...

background: the production of waste pollutants has become a major problem for many food and oil industries. however, oil wastes can provide alternative substrates for industry, which could help to solve environmental pollution problems. furthermore, oil wastes can be used as substrates to produce unsaturated fatty acids, which are important for health.objectives: the production of fatty acids i...
