Starch modification using reactive extrusion

This paper presents a review of the principle and technologies in reactive extrusion and their application in starch modification and preparation of starch derivatives, such as starch graft copolymers, glycosides, cationic starch, or oxidized starch. The applications of reactive extrusion in producing other biopolymers are also touched. Flexibility and efficiency of reactive extruders as reactors for biopolymers are particularly noteworthy.
