Unlike almost other vegetable oils, corn oil is obtained from the seed that contained 3%-5% oil. the maize germ accounted for about 6% to 8% of the corn granule.

 According to the different maize varieties andmaturities ,oil percentage is differernt too, usually it can reach  30%~48%

Method of germ extraction mainly half wet, dry.

Hydrometallurgy of embryo is the corn immersion, so as to achieve the purpose of embryo and starch separation, embryo extracting rate of 85% a 95% of the act,

germ moisture content as high as 60%, oil content of up to 44% 50%. dry germ extraction without water regulating on Maize by mechanical method, but the corn and wheat germ separation.

Half wet extracting embryo of maize is moistening to a moisture content of 16% - 20%, and then by peeling, crushing and extracting embryo, the embryo extraction efficiency can reach 85%

Raw material ---degerming ---cleaning (magnetic separation\ removing iron\stoning machine) ---soften---flaking---cooking---pressing
