Corn oil is a versatile vegetable oil that is widely used in cooking, baking, and salad dressings. It is extracted from the germ of corn kernels, and the process of making corn oil involves several steps. In this blog post, we will explore how corn oil is made step by step.
Step 1: Harvesting and Drying Corn
The first step in making corn oil is harvesting and drying corn. Corn is typically harvested in the fall, and the kernels are removed from the cob and dried to reduce their moisture content.
Step 2: Milling the Corn
Once the corn is dried, it is milled into smaller pieces. This process helps to separate the germ from the rest of the kernel.
Step 3: Extracting the Germ
The germ is the part of the corn kernel that contains the oil. To extract the germ, the milled corn is passed through a series of screens and separators.
Step 4: Pressing the Germ
The extracted germ is then pressed to release the oil. This can be done using a hydraulic press or an expeller.
Step 5: Refining the Oil
The crude corn oil obtained from pressing contains impurities, such as gums, waxes, and free fatty acids. To remove these impurities, the oil is refined through a series of processes, including degumming, neutralization, and bleaching.
Step 6: Deodorizing the Oil
After refining, the corn oil is deodorized to remove any remaining odors or flavors. This is done by passing the oil through a heated vacuum chamber.
Step 7: Packaging the Oil
The refined and deodorized corn oil is then packaged in bottles, cans, or other containers for distribution and sale.
