Cold Pressed

Laboratory-prepared wheat germ oil was obtained by cold pressing and supercritical CO<sub>2</sub> extraction. The main objective was to compare the quality of both oil samples obtained, with emphasis on their fatty acids compositions and tocopherol contents. The percentages of palmitic, oleic, linoleic, and linolenic acids determined in the cold-pressed oil were 15.89, 15.48, 54.88, and 7.34% of total fatty acids, respectively, and those in the oil extracted by supercritical CO<sub>2</sub> were 16.50, 15.05, 54.79, and 7.29% of total fatty acids, respectively. The average proportions of saturated, mono- and polyunsaturated fatty acids calculated for wheat germ oil obtained by cold pressing accounted for 17.15, 17.63, and 62.22% of total fatty acids, respectively, and those calculated for wheat germ oil extracted by supercritical CO<sub>2</sub> were very similar, accounting for 18.14, 17.58, and 62.08% of total fatty acids, respectively. As expected, the fatty acid profiles determined in both oils studied were observed to be almost identical. In contrast, the level of &alpha;-tocopherol in the oil extracted by supercritical CO<sub>2</sub> was found to be considerably higher (1.27 mg/g) than that in the oil obtained by the cold pressing procedure (0.79 mg/g). &nbsp;

Abstract The study was carried out in the poultry field of the Animal Production Department of the Faculty of Agriculture at Tikrit University. The current study aimed to estimate the effects of adding different percentages of octacosanol, wheat germ oil and rice oil to the ration on egg quality traits. 96 laying quail (age 45 days), were used and divided into six treatments were included: adding the octacosanol/kg feedstuff (T1 without adding, T2=15 mg, T3=20 mg, T4=25 mg), (T5) was adding 5 ml of wheat germ oil/kg feedstuff and (T6) wasadding 5 ml of rice oil/kg feedstuff, which each treatment included four replicates. It used three female quails for each one male, during 90 days at the age of 16 weeks. The results showed the following: no significant effect (P<0.05) of dietary octacosanol, wheat germ oil and rice oil supplementation which was recorded on relative weights of shell, yolk and albumen, and shell thickness also yolk color, egg shape index, albumen index, yolk index, egg quality of laying quail. However, there was a significant increase (P<0.05) in hough unit for the two treatments that it included octacosanol powder (20 and 25 mg) compared to the control treatment, However, there was no significant difference between the addition treatments.

Abstract. Background: Elevated homocysteine levels and malnutrition are frequently detected in hemodialysis patients and are believed to exacerbate cardiovascular comorbidities. Omega-3 fatty acids have been postulated to lower homocysteine levels by up-regulating metabolic enzymes and improving substrate availability for homocysteine degradation. Additionally, it has been suggested that prevention of folate depletion by vitamin E consumption decreases homocysteine levels. However, data on the effect of omega-3 fatty acids and/or vitamin E on homocysteine levels and nutritional status have been inconclusive. Therefore, this study was planned to examine the effect of combined supplementation of fish oil, as a source of omega-3 fatty acids, with wheat germ oil, as a source of vitamin E, on homocysteine and nutritional indices in hemodialysis patients. Methods: This study was a randomized, double-blind, placebo-controlled trial. Forty-six hemodialysis patients were randomly assigned to two equally-sized groups; a supplemented group who received 3000 mg/day of fish oil [1053 mg omega-3 fatty acids] plus 300 mg/day of wheat germ oil [0.765 mg vitamin E], and a matched placebo group who received placebo capsules for 4 months. Serum homocysteine and different nutritional indices were measured before and after the intervention. Results: Twenty patients in each group completed the study. At the end of the study, there were no significant changes in homocysteine levels and in the nutritional indices neither in the supplemented nor in the placebo-control groups (p > 0.05). Conclusions: Fish oil and wheat germ oil combination did not produce significant effects on serum homocysteine levels and nutritional indices of hemodialysis patients.
