The invention relates to a method of dewatering corn gluten stream wherincoagulant is add to the corn gluten streamof the corn wet milling process. The method of dewatering corn gluten uses aneffective amount of a coagulant of one or more anionicpolymers, the anionic polymers comprising one or more anionic monomers. Themethod further includes a process for separatingthe water from the gluten using a solids/liquids filtration device.
