Parameters Sunflower oil OLEO EM EMEX
TPC (mg GAE/g) 4.15 ± 0.14c 4.55 ± 0.17b 4.35 ± 0.08b 5.49 ± 0.19a
DPPH (%) 29.25 ± 0.13c 30.23 ± 0.24b 29.88 ± 0.27b 38.84 ± 0.68a
FFA (as % oleic acid) 2.77 ± 0.25a 2.63 ± 0.24a 2.59 ± 0.11a 2.70 ± 0.18a
PV (meq.O 2/kg sample) 3.51 ± 0.33a 3.44 ± 0.24a 3.65 ± 0.10a 3.45 ± 0.19a
