1, the cost is different.

Corn belongs to the high-yield crops, and widely distributed, not only our country, all over the world in the planting of corn, and our country also belongs to the corn planting countries, since the market is enough corn, then naturally the price of corn down, and to corn oil, then the cost will be correspondingly lower.

Peanuts in the world only part of the country has planted, and its growth on the climate and soil requirements are high, suitable for growth in a warm climate, moderate rainfall of sandy soil, and a longer growing period, compared with the cultivation of corn, large-scale planting is not as common as corn, although the distribution of our country is more widespread, but in general, the market supply of maize can not be compared to the cost is higher.

2, the number of different sources.

Because of the high yield of corn, processing costs are cheap, so corn oil will be supplied to the market, there will not be a sudden situation of demand exceeding supply. And peanut production is relatively low, to peanut oil to meet the oil requirements of all Chinese people is not realistic, and things are expensive, so the price will naturally rise.
