Summary
Corn vegetable oil is a type of cooking oil extracted from the germ of corn kernels. It’s widely used in cooking and baking due to its mild flavour and high smoke point, making it ideal for frying and sautéing. Rich in polyunsaturated fats, it can be a part of a balanced diet when used in moderation. It may benefit those looking to manage cholesterol levels, as it contains plant sterols that contribute to normal blood cholesterol levels.

What Is Corn Vegetable Oil?
Corn vegetable oil, also known as maize oil, is a type of edible oil extracted from the germ of corn (Zea mays). Its chemical name is triglyceride, and it primarily consists of polyunsaturated fatty acids. The empirical formula for a typical triglyceride is C55H98O6. Classified as a vegetable oil, it is usually found in a liquid form at room temperature. Corn oil is sourced through a process of pressing and solvent extraction from corn germ. It is commonly used in cooking due to its high smoke point and neutral flavour, and it contributes to normal cholesterol levels when replacing saturated fats in the diet. In supplements, corn oil is frequently used as a carrier oil in softgel capsules, helping to dissolve and deliver fat-soluble vitamins and other active ingredients effectively.
How It Works In The Body
Corn vegetable oil is a source of energy and provides essential fatty acids, which are important for maintaining cell structure and function. It contains polyunsaturated fats, including omega-6 fatty acids, which contribute to normal blood cholesterol levels. When consumed, the body breaks down the oil into fatty acids and glycerol, which are then used for energy or stored for later use.
