Corn oil is made from corn germ. Generally speaking, 100 kg of corn can yield about 3 kg of oil, so every 33 kg of corn can yield about 1 kg of oil.

In general, the oil content of corn is about 5%, and the oil content of high-oil corn is above 8%. Corn oil needs to be extracted from corn germ, so it is difficult to extract corn oil, with low oil yield and high price.
