Corn Oil
Corn Oil is a versatile, plant-based oil extracted from the germ of corn kernels (Zea mays) through mechanical pressing and solvent extraction, followed by refining. It is light yellow in color with a mild, neutral scent and a high smoke point, making it suitable for culinary, industrial, cosmetic, and pharmaceutical applications. Rich in polyunsaturated fatty acids, especially linoleic acid, and vitamin E, corn oil is valued for its emollient, antioxidant, and cholesterol-lowering properties.
Commonly used as a cooking and frying oil, it is also widely incorporated into margarine, salad dressings, and processed foods. In cosmetics, it functions as a skin-conditioning agent and emollient. Corn oil further finds use in pharmaceutical formulations, biofuel production, and industrial lubricants.
