Research topic

Design of soft-solid products for sustainable special diets: rheological, tribological and nutritional evaluations


Project Synopsis

Swallowing difficulties can lead to reduced food intake and an increased risk of aspiration pneumonia and choking. This PhD project aims to design novel soft-solid foods based on upcycled agri-food waste, in order to develop functional products suitable for people with swallowing difficulties.

The research will be carried out within the framework of applied materials science to thoroughly investigate the rheological and tribological aspects of oral processing, specifically swallowing, to provide a basis for improving already available commercial products. Rheological and tribological tests will be performed to assess how mesostructure can deeply affect swallowing. Phenomenological and mathematical models of relevant aspects of swallowing will be developed in partnership with modeling engineers.

The project will involve collaboration with neuropsychologists with expertise in swallowing disorders. Findings will be shared within the “PNRR-PE10-SPOKE 4-DYSPHAGIA” activities, focused on designing nutrient-rich products that fulfill the specific texture and swallowing requirements of dysphagia patients.
