Mr Vincent used micro-rheological techniques to study the mechanical properties of pectin gels at the micron scale, in order to give essential information on how the pectin chains assemble in networks. Pectin is a ubiquitous biopolymer found in plant cell walls, with a wide range of applications for the food and pharmaceutical industries. In particular, its gelling abilities play an important role in many biological functions. The thesis provides a process to maximize the strength of pectin gels. Further, the understanding of the pectin networks gained from mimicking in-vivo assembly processes also leads to vast applications. These outcomes will not only shed light on the in-vivo control properties of plant cell walls. By using the latest chemical-physics theories, the findings will also allow the design of many new food materials with optimized properties.
