Abstract

|
A study was conducted for process conditions for maximum yield of crude soy lecithins and its quality improvement by solvent extraction. Fesuits indicate that maximum yield of he crude lecithins was obtained by hydration with 3% water at degumming temperature 75℃. On the other hand, water level used for hydration was found to affect the recovery yield of the lecithins more profoundly than the degumming temperature. It was also found that extractiors with acetone and 2-propanol increased the phosphatidy choline content from 19.7% to 28.3% and 58%, respectively.
