Abstract
Abstract THE INVENTION RELATES TO A METHOD OF REFINING EDIBLE VEGETABLE AND MARINE OILS. VEGETABLE AND MARINE OILS TEND TO REVERT IN FLAVOR AND ORDOR ON STORAGE. TREATING SUCH OILS WITH SMALL AMOUNTS OF HYDROGEN CHLORIDE UNDER SUBSTANTIALLY ANHYDROUS CONDITIONS SUBSTANTIALLY PREVENTS THE OILS FROM UNDERGOINING REVERSION ON STORAGE. ALSO, WHEN OILS WHICH HAVE REVERTED ARE TREATED WITH SMALL AMOUNTS OF HYDROGEN CHLORIDE UNDER SUBSTANTIALLY ANHYDROUS CONDITIONS THE ORIGINAL BLAND FLAVOR OF THE OILS IS RESTORED.
