Actual position and research subject

Current position: PhD student in the ISD team
PhD project: Food emulsions stabilised by plant protein ingredients obtained by gentle fractionation: From formulation to digestion

This project aims to explore the chemical composition, structural organisation and functionality of commercial plant protein ingredients derived from pea and lupin (isolates and concentrates). For the first time, we have identified and characterised endogenous lipids, about half of which are phospholipids, in these plant protein ingredients. We then set out to understand their potential impact on emulsifying and interfacial properties. In particular, we studied the competitive interactions between lipids and proteins at the oil-water interface using interfacial rheology. Finally, we analysed the digestive fate of these emulsions using in vitro digestion, in order to understand how their interfacial microstructure affects their lipolysis kinetics.

Supervisors: Claire Berton-Carabin, Alain Riaublanc, Anne Meynier
