Topic description
L'objectif de cette thèse est de comprendre le rôle joué par les interactions polysaccharides-polysaccharides et polysaccharides-eau sur les propriétés macroscopiques de la matière végétale transformée, en particulier au travers d'itinéraires technologiques provoquant la déstructuration et l'hornification des polysaccharidiques pariétaux. Plus spécifiquement, il s'agit de comprendre, à l'échelle moléculaire, l'effet des traitements thermomécaniques de déstructuration (cuisson-extrusion) et de restructuration (thermocompression) des sous-produits de la pomme sur leurs propriétés macroscopiques dans les formulations alimentaires, lors de l'ingestion puis de la digestion.

The aim of this thesis is to understand the role played by polysaccharide-polysaccharide and polysaccharide-water interactions on the macroscopic properties of processed plant matter, in particular during technological pathways causing destructuration and hornification of cell-wall polysaccharides. More specifically, the aim is to understand, at a molecular scale, the effect of thermomechanical destructuring (cooking-extrusion) and restructuring (thermocompression) treatments of apple by-products on their macroscopic properties in food formulations, during ingestion and then digestion.
