Color Reversion of Refined Vegetable Oils: A Review
Refined vegetable oils, after degumming, deacidification, bleaching, deodorization, and dewaxing, appear pale yellow or amber when they are freshly prepared. However, during transport, storage, and consumption, the color of some vegetable oils gradually darkens and turns deep yellow or light red. This phenomenon is known as the color reversion

What Is Vegetable Oil?
Vegetable oil is a mild, odorless, flavorless, light-colored cooking oil that is good for cooking, frying and for making salad dressings. Any oil made from plants, whether it's derived from seeds, grains, nuts or fruits, is considered a vegetable oil. But when you see a bottle of oil labeled "vegetable oil," it's almost always soybean oil.

Heat Transfer Properties of a Series of Oxidized and Unoxidized Vegetable Oils in Comparison with Petroleum Oil-Based Quenchants - Springer
Vegetable oils, especially soybean oil, exhibit substantially poorer thermal-oxidative stability than commercially available petroleum oil quenchant formulations. Therefore, to achieve any commercially interesting performance, vegetable oils must be stabilized by the addition of antioxidant inhibitors.

Edible oil refining
Edible oil refining is a set of processes or treatments necessary to turn vegetable raw oil into edible oil. Raw vegetable oil, obtained from seeds by pressing, solvent extraction, contains free fatty acids and other components such as phospholipids, waxes, peroxides, aldehydes, and ketones, which contribute to undesirable flavor, odor, and appearance; for these reasons, all the oil has to be
