Abstract: Deacidification,dehydration,decolorization and deodourization were conducted to refine kiwifruit seed oil,and their conditions were optimized respectively. The results showed that:(1) The best deacidification conditions are:initial temperature 35 ℃,concentration of lye 9%,lye-adding time 5 min,agitation speed 60 r/min,temperature-holding sedimentation time 8 h.(2) The best dehydration conditions are dehydration temperature 105 ℃,dehydration time 55 min,agitation speed 45 r/min,and dehydrated vacuum degree of vacuum container 0.08 MPa.(3) The best decolorization conditions are:active argil amount 2.5%,decolorization temperature 95 ℃,vacuum degree 0.08 MPa,time 30 min,and agitation speed 55 to 60 r/min.(4) The best deodourization conditions are:deodourization temperature 150 ℃,time 2.5 h,and vacuum degree 0.08 MPa. After deodourization,the refined kiwifruit seed oil was added with N2 to break vacuum degree sufficiently and then be cooled to 0 to 5 ℃ for storage.
