showed low hydroperoxides and malondialdehyde content, they reportedly had higher conjugated dienes and triene. The fish group showed the highest malondialdehyde content and panisidine value . In a similar study reported that frying chicken drumsticks produces a higher amount of free fatty acid in corn oil than frying french fries . However, the effect of fried food on the change of polar compounds such as triglyceride dimer, oxidised triglyceride monomer, and diglyceride was less pronounced than the effect of the type of oil .
