How to turn cellulose waste into value-added materials- several novel techniques for cellulose development.

PhD defence, Friday 19 August 2022. Ziqian Li.

Ziqian Li

During her studies, Ziqian Li researched novel and effective techniques for the depolymerization of cellulose, and modification for food application. The inherent high-crystalline structure of cellulose limits its development, and thereby three effective methods are investigated to break up the chains-entangled structure of cellulose. For the development of cellulose as an Energy-free Ingredient in the emulsion systems including milk and ice cream, some modification of cellulose was applied.

The new research findings contribute to the understanding of how cellulose is depolymerized, modified, and served as a fat substitute or Energy-free Ingredient in the emulsion system for food application.

The PhD study was completed at Department of Biological and Chemical Engineering, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
