The oils antiradical efficiency was calculated from the EC50value, and findings showed 2.04 × 10−2and 2.06 × 10−2to pulp and seed, respectively. Siger et al. (2008) found similar value to soybean oil (2.94 × 10−2) and larger values for oils from sun flower(5.92 × 10−2), grape seed (6.28 × 10−2) and canola (10.31 × 10−2).
