Corn maize germ oil is extracted from the germ of maize (Zea mays), the small portion of the kernel that is rich in oil. It contains about 50% polyunsaturated fatty acids, including linoleic acid, making it a heart-healthy choice for cooking and frying. Corn oil is light in flavour, has a high smoke point, and is widely used in processed foods, snacks, and margarines.

Beyond the kitchen, it serves as a feedstock for biodiesel production and an ingredient in soaps, paints, and lubricants. The oil is also valued in the pharmaceutical and cosmetics industries for its stability and mild profile. The residual meal after oil extraction is a high-protein feed component for livestock. Corn maize germ oil is produced in large volumes in the United States, China, Brazil, and Argentina, aligning with global maize cultivation. Its balance of functionality, health benefits, and industrial use makes it an essential player in the global vegetable oil market.
