Abstract
The effects of ultrasound treatment (30 kHz, 100 W, 30 s), Ultraviolet (UV) irradiation (30 min), and marzeh khuzistani essential oil (0.08%) extracted by ohmic ultrasonic extractor on oxidation of canola oil were studied. GC-MS analyses of marzeh khuzistani essential oil (EO) revealed that carvacrol (88.6%) was the major component of EO. Peroxide value (PV), Anisidine value (AnV), Thiobarbituric acid (TBA) value, free fatty acid (FFA), iodine value (IV), and induction period (IP) were measured in canola oil and showed that EO had an antioxidant effect in comparison to BHT in sample oils treated or no treated by ultrasound and UV. In addition, EO was able to reduce the stable 2, 2-diphenyl-1-picrylhydrazyl free radical (DPPH) with a 50% inhibition concentration (IC50) of 29 ± 0.06 μg/mL. The results indicate that ultrasound and UV treatment increase oil oxidation but EO can act as antioxidant and increase oil stability. Therefore, EO could be used as a natural antioxidant in oils for food uses.
