- The nonhydratable phosphatides, which are the calcium and magnesium salts of phosphatidic acid and phosphatidyl ethanolamine, remain in the oil after water degumming.
- The amount of the nonhydratable phosphatides in the oil is related to the general quality of the oil and, in particular, to the degree of action of the enzyme phospholipase.
This enzyme is responsible for the production of phosphatidic acid from hydratable phosphatides
