Abstract: The chill-fractionted extraction technology soy oil with isopropyl alcohol(IPA)was studied and the energy consumtions were compared with the tradition methods so as to decide concentrations of isopropyl alcohol with miscellas and temperature effects on upper and lower phase.The changes of different oil contents and concentration effects of free fatty acid and phospholipid during the process were discussed.The study prove the feasibility of isopropyl alcohol to take the place of n-hexane.

Key words: isopropyl alcohol, extraction, chill-fractionted
