Among the important advantages of solvent as compared with conventional winterization of soybean oil are the speed of operation and increased yields up to 25%. Easier and faster filtration results with the solvent system despite the high yields of solids when low iodine value (IV) oils are winterized at low temperatures. Hydrogenated stocks with IV as low as 90 can be winterized easily at temperatures of 蜢16C. The time of winterization can be reduced from several days to a few hours. With all the variations possible in IV, temperature, and solvent selectivity, liquid soybean oil can be produced with specified characteristics and with a minimum linolenate content. Acetone was the best solvent tested for winterization.
