For the last twenty years

research interested into the use of natural biopolymers

which was a way of preventing environment pollution

putting into effect of green chemistry and development of human being in perfect harmony. Gluten was a byproduct of cereal industry which was abundant

biodegradable and reproducible biopolymer. Because of its viscoelasticity

extensibility

film-forming and thermosetting

people paid more attention to gluten

which could be used as raw materials for polymer products in technical applications as well as food additives. The present paper reviewed the composition of wheat gluten

the principles and methods for chemical modification

physical changing and enzyme reaction of wheat gluten. Besides

the application and prospect of gluten was also described.
