Abstract
The factor of 30 recommended by the official AOCS method Ca 12-55 for converting phosphorus to phosphatides in soybean oil is in reality a conversion factor to “acetone insolubles.” While applicable to crude soybean oils, its applications to degummed and refined oils is open to question. A corresponding revision of the method Ca 12-55 seems therefore indicated.
