Production of trans-fat-free margarine prepared using catfish oil and palm stearin with the addition of avocado waste oil for tocopherol enrichment

Catfish oil (CFO) is rich in unsaturated fatty acids (UFA) which are potentially produced into margarine through the blending method with palm stearin (PS) addition. The high UFA content of CFO causes margarine to be susceptible to oxidative damage, which can also trigger the formation of trans fatty acids (TFA). An antioxidant compound in the form of avocado waste oil (AWO) that contains tocopherol is added during margarine production to inhibit oxidative damage and TFA formation in the final...
