aSoybean oil with approximately 900 ppm P; bAD batch where only the acid degumming step followed by caustic neutralization was performed; ccomplete degumming: acid treatment, caustic neutralization, and enzymatic reactions with different phospholipases. Phosphorus content expressed in ppm. AD, acid degumming; PLA1, phospholipase A1; PLC, phospholipase C; LLPL-2, lyso-phospholipase.
