Find out how easy it is to produce high-quality corn oil
Corn oil is extracted from the corn germs, which are previously separated from the grain. Corn germ extraction is usually carried out during starch production. For oil extraction, the cold pressing process and / or extraction using hexane is used.
The corn germs are gently pre-heated to the pressing temperature and then added to a screw press. The obtained products, corn oil and corn press cake are immediately processed. The press cake is crushed and cooled before being transferred for further processing or storage. The oil obtained is usually purified to pure oil in several purification stages (coarse filtration, fine filtration, safety filtration).
Properties and shelf life of corn oil
Good corn oil should be clear and yellowish to reddish. In addition, have a green nutty / sweet smell. The cold-pressed corn oil has a high content of unsaturated fatty acids and vitamin E. Therefore, it is very sensitive to heat.
The solidification point is in the range of about -10 to -18°C. To prevent the oil from going rancid, it should be stored in a cool, darkened place. In this way, a shelf life of about 12 months can be achieved.
