Studies on Variations of Phospholipid Compositions in Soybean Oil Production

The phospholipid contents in crude extracted oil and degummed oil from intermediates of soybean pre proccssing were determined to find out the variations of phospholipid contentsand constitulions.The factors affecting the contents of phospholipid fractions,as well as the measures to lower the contents of non hydratable phospholipid in crude extracted oil were discussed.
