Irradiation Effect on Oxidative Condition and Tocopherol Content of Vegetable Oils

Irradiation Effect on Oxidative Condition and Tocopherol Content of Vegetable Oils

The effect on induction period and tocopherol content after γ-irradiation onsamples of olive oil and seed oils (sunflower and soybean) was determined. In seed oilsamples 0, 100, 200 and 300 ppm of δ-tocopherol were added before irradiation with 1, 2and 3kGy. The results of induction period sho...
