Abstract A procedure to measure phosphorus content of soybean and corn oil samples has been developed using nephelometry (turbidity). The method uses the relationship between phosphorus level due to phosphatides in vegetable oil and turbidity formed in phosphatide mixtures. The rapid 10‐min determination of phosphorus in process samples is 30 times faster than colorimetric methods. Phosphorus vs turbidity data formed nearly linear relationships for crude, degummed, once‐refined, bleached and deodorized soybean and corn oil process samples.
