On-going research focuses on:
- Biopolymers based on natural and modified pectins with regard to their emulsifying and stabilizing properties: influence of production conditions with focus on extraction; identification of relevant molecule groups with regard to molecule design
- Micro-gel particles based on pectins: production pathways and their influence on micro-gel characteristics, application in food systems
- Characterization of the structure and dynamics of fluid-fluid interfaces stabilized with biopolymers
Our research is motivated by the chance to create emulsions with specific morphology, stability and release properties only by using natural biopolymers as additives. We develop analytical tools to understand and investigate stabilization mechanisms of pectin-based biopolymers and micro-gel particles on a fundamental level. We use this knowledge to propose molecular modifications within relevant legislation frameworks to create food-grade ingredients with targeted texturizing, stabilzation and encapsulation functionality. Furthermore, we develop emulsification processes that are designed to cope with challenges posed by the use of these biopolymers. Besides structure and stability analysis of emulsions, the methods involved comprise (interfacial) rheological characterization techniques as well as chemical preparative and analytical techniques. Our main cooperation partners are within polymer and material science as well as food chemistry with applications in the food, pharmaceutical, cosmetic and chemical industry.
