Storage Stability of Crude Cotton Oil with Respect to Carotenoids and Total Tocopherol by Comparing with Refined Cotton Oil
Abstract: The antioxidant potential of sesame and sunflower meal acetone extracts was investigated in crude cotton oil (CCO) containing natural ocurring antioxidants such as carotenoids and tocopherols and also compared with synthetic antioxidants. Storage stability of CCO was examined by measuring carotenoids and total tocopherols during storage period of 120 days at 50 C. Carotenoids and total tocopherols were degraded during accelerated storage. Results showed that tertiary butylated hydroxy quinone (TBHQ) was most effective antioxidants. Sesame and sunflower meal extracts could lower the degradation of carotenoids and tocopherols during storage period of 120 days and have high antioxidant efficacy against oil oxidation even higher than propyl gallate (PG). Among both meal extracts, sesame meal extract is more effective against vegetable oil protection than sunflower meal extracts.
