Effects of Vegetable Oils on The Quality Parameters of Red Pepper During Storage

Sunflower, cottonseed, hazelnut, soybean and sesame oils at the concentration of 0, 2, 4 or 6 g/100g red pepper were added into red pepper to determine the effects of the oils on color and oxidative stability during 12-month storage at room temperature. The changes in color, free fatty acid content and peroxide value were determined in 2 month intervals. Initial colors of samples were ranged between 75.26 and 79.95 (ASTA unit), and decreased as the amount of the added vegetable oils increased. Color losses were increased by increasing time for all samples while the color of the soybean oil added samples was more stable. Free fatty acid content and peroxide value of red pepper extracted oils increased significantly as the storage time increased. At the end of storage, free fatty acid content of sesame oil added red pepper was higher than that of others and the lower peroxide value was observed in the control.
