Corn oil is made from corn germ. Like many edible grains, corn is primarily cultivated for the purpose of separating the starch and protein contained in it, and corn oil is a byproduct of companies that produce starch powder. Oil is about 1.3-5.7% of the weight of corn kernels. About 83% of the oil is in the bud, 15% in the endosperm (kernel), 1.3% in the shell and 0.7% in the ridge of the cap. Corn germ is the part rich in corn oil, which is separated from the kernel by dry or wet milling before oil extraction. Then, the dried seeds are put through spiral or spiral presses at medium temperature and high pressure to extract the oil from the bud. This crude oil must go through stages such as degumming, alkaline purification, decolorization, winterization and deodorization. In the refining process, free fatty acids, phospholipids and unwanted harmful substances and colored substances are removed from the crude oil and valuable properties including pleasant taste and resistance to smoking, color change and flavoring are given to the oil. Golshad’s useful oil is offered in two sizes: 800 grams (900 ml) and 1620 grams (1.8 liters).
