Abstract: In this paper, the isolation and purification methods of hemicellulose were viewed, including alkali extraction, alkali peroxides extraction, organic solvent extraction, ultrasound-assisted separation, microwave-assisted separation, steam explosion and hot water treatment method. The advantages and disadvantages of each method were compared. Besides, several important hemicellulose modified products and their application fields were also introduced, and the developing direction of hemicellulose derivatives in the future was prospected.

Key words: hemicellulose, separation method, derivatives
