Abstract
Abstract Methods of enhancing the dewatering of gluten are disclosed. The methods comprise adding a nonionic surfactant to the wet gluten prior to dewatering, as in vacuum dewatering equipment. Particularly effective surfactants are oxyalkylated sorbiton R surfactants when R is monooleate, trioleate, monostearate, tristearate, monopalmitate and monolaurate.
