摘要：

The effect of alpha-, gamma-, and delta-tocopherols (enrichment: 1000 ppm) on the peroxide formation in rapeseed oil triacylglycerols (RSOTG) was evaluated. The oxidation process was initiated by gamma-irradiation with doses of 4 and 10 kGy. Whereas a pronounced antioxidant effect was observed for gamma- and delta-tocopherol (sequence: delta- > gamma-tocopherol), the inhibition extent of alpha-tocopherol was insignificant.
