Beschreibung
Zusammenfassung:	The invention relates to a method for preparing a wheat separation protein, in particular to purification and modification of a wheat separation protein with high purity. The method comprises the following steps: gluten powder which is a byproduct of starch prepared by wheat is subjected to acid-alkali extraction, separation purification, high-temperature bactericidal treatment and spray drying to obtain the powdery vegetable protein with the purity of more than 90 percent used for food additives. The wheat separation protein with high purity is light yellow, and has fine and uniform particles, and unique wheat flavor rather than natural fishy smell of the soybean separation protein; moreover, the dry based crude protein content of the wheat separation protein is as high as more than 90 percent.
