| Abstract | ||
| The study was conducted in order to use the Rhodoturulla glutinis strain species in oil production and estimation of oil content from fatty acids content and some of its basic components, especially Tocopherols and Phenolic compounds and determine oxidative stability and oil viscosity level output. In addition to determining the quality of oil product after cooking temperature for 3 hours by detection the oil oxidation stability and the viscosity of oil produced compared with oil of both maize and sunflowers. The results showed that the quantity of oil produced from yeast strain Rho.glutinis was at 5.8 g/l with dry biomass produced at 19.6 g. the oil contains the fatty acids as Linoleic, Palmitic, Oleic, Meristic, Stearic and Linolenic acid at 34.6, 26.4, 24.2, 2.5, 6.0 and 3.0% respectively. It also contains the Tocopherols types at 58.5 mg/100 ml compared with the content of both corn and sunflower oil were at 70.4 and 63.6 mg/100 ml, respectively. And contain the phenolic compounds at 3.6 mg/100 g of oil, which was more than in both corn and sunflower oil. It turns out that oil output from yeast were more efficient in the bear to heat exposure continued with 7.6 hours compared with both corn oil and sunflower were at 4.1 and 5.2 hours respectively. As well as showing that better also in low level in viscosity after exposure to 125 º c where became at 8.4 degrees compared to both corn oil and sunflower were at 6.3 and 7.4 respectively. we conclusion from the study that yeast strain Rho.glutinis was so high efficiency in oil production and it is fit for human consumption and therefore high quality cooking uses depending on criteria examined and compared with both corn oil and sunflower. | ||
