Dr Fengwei Xie

Postdoctoral Fesearch Fellow

Academic Background

• PhD (Polysaccharide Engineering), South China University of Technology, China, 2009

• B.Sc. (Biological Engineering), South China University of Technology, China, 2004/p>

Research Interests

Extrusion processing

• Extrusion of starch-based materials
• Blending starch with biodegradable polymers (including biopolyesters)
• Reactive extrusion

• Develop new methods to study the phase transitions of starch under shear and low-moisture conditions (just as during an extrusion processing)

• Extrusion rheology of starch-based materials as functions of amylose/amylopectin ratio, temperature, moisture content, blend contents, extrusion conditions, etc.

• Preparation and evaluation of novel starch polymer nanocomposites
