Abstract: MODIFIED LACITHIN PRODUCTS EXHIBITING IMPROVED EMULSIFICATION PROPERTIES ARE DIRECTLY OBTAINED FROM CRUDE VEGETABLE OILS UNDER AN INTEGRATED AND CONTINUOUS PROCESS. THE CRUDE OILS ARE INITIALLY TREATED WITH A SMALL AMOUNT OF AQUEOUS ACID ANHYDRIDE WITH THE RESULTANT ACETYLATED WET GUM BEING PARTITIONED FROM THE CRUDE OIL. THE ACETYLATED WET GUM IS THEN ADMIXED WITH A BASE AND SUBJECTED TO CONTROLLED PROCESS CONDITIONS UNDER ELEVATED DRYING CONDITIONS TO PROVDE A DRY MODIFIED LECITHIN PRODUCT HAVING AN ACID VALUE OF ABOUT 10 TO ABOUT 25.
