he two degumming processes using EDTA [2, 3] illustrateanother crucial aspect: the importance of ensuring a fine disper-sion. The process that does not insist on the creation of a fine dis-persion [2] requires an emulsifier to ensure that the EDTA reactswith the NHP. In the Deffense process [3] on the other hand, thedispersion is so fine that the EDTA reacts with all NHP present inthe oil before the dispersion coalesces and reaction rate slowsdown.
