Abstract

This study shows the quality Indices of edible vegetable oils. The quality of deep-fried oil is affected by several processes such as hydrolysis, oxidation, and polymerization, which in turn alters the flavor stability, and reduces tocopherols and fatty acids in Oil. Palm olein (PO), Refined sunflower oil (RSO), Sesame oil (SO), Groundnut oil (GO), Rice bran oil (RBO), Coconut oil (CO), Virgin coconut oil (VCO), Cold press sesame oil (CSO) and Cold press groundnut oil (CGO) were used in the current study. Oils were fortified with α-tocopherols, retinol, calciferol, and phytonadione of fat-soluble vitamins and were heated at 220°C. Physicochemical characteristics (Primary, secondary, tertiary oxidation) were studied to determine the stability of fortified oil samples. Acid value (mg NaoH/g) of deep-fried coconut oil, groundnut oil, sesame oil, rice bran oil, Palmolein oil, and Refined sunflower oil at 200-220°C is 1.43, 1.55, 7.3, 1.2, 1.13, 1.6 respectively. Peroxide value (meq of active O2/Kg) of deep-fried dried coconut oil, groundnut oil, sesame oil, rice bran oil, Palmolein oil, and refined sunflower oil at 200-220°C is 1.25, 2.6, 3.2, 1.5, 6.98, and 2.25. Iodine value (g of iodine per 100 g oil) of deep-fried coconut oil, groundnut oil, sesame oil, rice bran oil, Palmolein oil, and refined sunflower oil at 200-220°C is 10.6, 99.09, 121.1, 104.45, 63.01, 144.23. After processing at the temperature of 200-220°C, the fortified vitamins have deteriorated.
