Irradiation Effect on Oxidative Condition and Tocopherol Content of Vegetable Oils
نویسندگان
چکیده
The effect on induction period and tocopherol content after γ-irradiation on samples of olive oil and seed oils (sunflower and soybean) was determined. In seed oil samples 0, 100, 200 and 300 ppm of δ-tocopherol were added before irradiation with 1, 2 and 3kGy. The results of induction period showed that, after irradiation, all samples presented a significant decreased in resistance to oxidation. However, this decrease was minimized when δ-tocopherol was added. Irradiation significantly decreased the level of tocopherols. δ-Tocopherol appeared more sensitive in irradiation process than αand γ-tocopherol. The addition of δ-tocopherol significantly reduced, in most cases, the depletion of the other tocopherols.

Contribution of the Ratio of Tocopherol Homologs to the Oxidative Stability of Commercial Vegetable Oils.
The antioxidant activity of tocopherols in vegetable oils was shown to chiefly depend on the amount and the tocopherol homolog present. However, the most effective ratio of tocopherol homologs with regard to the antioxidant capacity has not been elucidated so far. The present study analyzed the effect of different tocopherol concentrations, homologs and ratios of homologs on markers of lipid ox...

متن کاملOxidative stability index of vegetable oils In binary mixtures with meadowfoam oil
The oxidative stability indices (OSI) of several vegetable oils were determined at 11O°e. Meadowfoam oil, Limnanthes alba, was found to be the most stable oil with an OSI time of 67.3 h for refined oil and 246.9 h for crude oil. Other oils with good oxidative stabilities were refined high oleic sunflower and crude jojoba oil (Simmondsia chinensis) with OSI times of 49.8 and 34.5 h respectively....

The influence of fatty acid composition and tocopherol on cholesterol oxidation in fish, flax, sunflower, and palm oil to which cholesterol was added were examined during storage and heating. The contents of cholesterol oxides in all oils increased (p < 0.05) during storage and heating. Total cholesterol oxides in fish oil were higher (p < 0.05) than that in vegetable oils. Addition of R-tocoph...
