摘　　要：目的:探讨采用冬化分提技术降低大豆油中的棕榈酸含量。方法:通过单因素试验考察冬化温度、正己烷添加量、冬化时间对降低大豆油中的棕榈酸含量的影响。结果:冬化温度-25℃、正己烷投入量(V_(正己烷)/V_(大豆油))2.5~4.0、冬化时间不小于18 h,能够获得棕榈酸含量低于14%的大豆油,收率介于30%~75%之间。结论:在添加正己烷的前提下,通过冬化可将大豆油中的棕榈酸含量控制在14%以下。Object:Discussion on using winterization fractionation technology to reduce palmitic acid content in Soybean oil.Method:A single factor experiment was used to investigate the effects of winterization temperature,n-hexane addition,and winterization time on the reduction of palmitic acid content in Soybean oil.Results:Winterization temperature is -25℃,n-hexane input(V_(n-hexane)/V_(Soybean oil))2.5~4.0,winterization time is not less than 18 h,Soybean oil with palmitic acid content less than 14% can be obtained,and the yield is between 30%~75%.Conclusion:Under the premise of adding n-hexane,the palmitic acid content of Soybean oil can be controlled below 14% by winterization.
