ABSTRACT
Curcumin (40, 80, and 120 μg/mL), β-carotene (5, 10, and 20 μg/mL), and TBHQ (200 μg/mL) were
used to test how well they protected corn oil from oxidation under accelerated oxidation conditions.
Linoleic acid has the highest amount (51.1 %), while linolenic acid has the lowest content (1.3%). Corn
oil supplemented with 200 μg/mL TBHQ was shown to have the longest induction time (12.9 h) of the
oils studied, followed by corn oil supplemented with 20 μg/mL β-carotene (11.78 h) and 40 μg/mL
curcumin (11.53 h). Curcumin, and β-carotene showed greater antioxidant potential in all tested samples
compared to the control in the accelerated storage experiment. Curcumin and β-carotene can potentially
improve the shelf life of corn oil compared with TBHQ-200 μg/mL. It can be concluded that curcumin,
and β-carotene were found to be effective antioxidants activity at 40, 80, and 120 μg/mL for curcumin
and 5, 10, and 20 μg/mL for β-carotene, so TBHQ was not required.
