As hydrogen donors, antioxidants donate a hydrogen to quench the free radicals being formed and delay or slow down the next phase of the reaction, propagation. This ultimately can delay rancidity.

Which oil is highest in antioxidants?

Results showed that sesame oil had the highest FRAP value (803 microM), followed by canola oil (400 microM), and sunflower, peanut, corn and olive oils (100-153 microM). Oils with higher intrinsic antioxidant content showed higher resistance to oxidation, although this was not statistically significant.
