Corn oil extraction is a complex process that involves several stages to ensure the highest quality oil is produced from corn germ. The process typically includes the following steps:

A. Pre-treatment of Corn
1. Cleaning: Corn is cleaned to remove any foreign materials such as dirt, stones, and other impurities.
2. Soaking: The corn is soaked in water to soften the kernels, which facilitates the separation of the germ from the endosperm.

B. Germ Separation
1. Grinding: The softened corn is ground to break the kernels and release the germ.
2. Sieving: The ground corn is then sieved to separate the germ from the endosperm and other parts.

C. Drying of Germ
1. Drying: The separated germ is dried to reduce its moisture content, which is essential for the oil extraction process. This step can be done using various methods such as tray drying, fluid bed drying, or spray drying.

D. Oil Extraction
1. Flaking: The dried germ is flaked to increase the surface area for efficient oil extraction.
2. Cooking: The flakes are cooked to adjust the moisture content and temperature, which prepares the material for the extraction process.
3. Extraction: There are two primary methods for extracting oil from corn germ:
- Mechanical Pressing: The flaked germ is pressed under high pressure to extract the oil.
- Solvent Extraction: A solvent, such as hexane, is used to dissolve the oil from the flaked germ.

E. Refining of the Extracted Oil
1. Degumming: The crude oil is treated to remove phospholipids and other gums.
2. Neutralization: Free fatty acids are neutralized to improve the oil's quality.
3. Bleaching: The oil is bleached to remove color bodies and impurities.
