Mycotoxins are primarily zearalenone which is difficult to remove and, by its nature, is residual and not easily destroyed and also has a toxic effect on humans. If the zearalenone is added to the animal body for a long time, the zearalenone is continuously accumulated in the animal body and deposited in the animal body. It acts like estrogen in animals and causes estrogen overload. Under the condition of acute poisoning, the traditional Chinese medicine has toxic action on nervous system, heart, kidney, liver and lung, and the main mechanism is that the traditional Chinese medicine can cause the nervous system to be excited, and a plurality of bleeding points are caused in organs, so that animals die suddenly. The female sensitivity is higher than that of a male, the fertility is reduced, the behavior is abnormal, meanwhile, the female animals are easy to be infertile, aborted or weakened, and the feminization of the male animals is caused. In addition, the over refining of oil and fat can not only cause the waste of resources and energy sources, but also cause the loss of nutrient elements (such as vitamin E and sterol contents) of the corn oil, CN201210561407.2 discloses a zero trans fatty acid corn oil and a refining process thereof, which produces the corn oil with zero trans fatty acid by proper processing of the corn oil through alkali refining, dewaxing, decoloring, deodorizing, packaging technologies and the like of the corn crude oil, and the prepared corn oil with the zero trans fatty acid has the trans fatty acid content of less than or equal to 0.3 percent, the vitamin E content of more than or equal to 1000mg/kg and the phytosterol content of more than or equal to 10000mg/kg, but has the defects that the zearalenone toxin in the corn oil is not removed, and the corn oil is treated by concentrated alkali liquor of 10 DEG Be-20 DEG Be after the phosphoric acid treatment in the alkali refining process, the nutrient substances of the corn oil are destroyed, and simultaneously, in the deodorizing stage, the temperature rise time is long, trans-fatty acid is easily formed in the corn oil under the conditions of long time, high temperature and the like, and the loss of nutritional ingredients is serious.
