Abstract:
1. A process of extracting oil from raw corn, including the steps of: providing a reagent solution including ethanol having a concentration between 90-100%; mixing said reagent solution with the raw corn at a temperature between 50° C. and 90° C. to form an extraction solution comprising ethanol and compounds from the raw corn, said compounds including extracted oil, extracted protein mixture and corn solids; separating said extraction solution into corn solids and a filtrate, said filtrate comprising extracted oil and extracted protein compound mixture; membrane filtering the filtrate to pass an ethanol mixture through the membrane, said ethanol mixture containing ethanol and extracted oil to thereby separate a substantial amount of said extracted protein compound mixture; membrane filtering the ethanol mixture to restrain a substantial amount of said extracted oil for oil collection.
