Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

Reminder of thermodynamic
Water, hydrophobicity, hydrophobic interactives Rheology Colloïdal systems Colloïdal stability (electrostatic stabilization and DLVO theory) Zeta potential Surface tension and surface free energy - cohesion and adhesion energies - spreading coefficient - Gibbs adsorption isotherm Physical states of matter Soft matter Emulsifiers properties : hydrophile-lipophile balance, phase diagram, CMC

Learning outcomes of the learning unit

To lay the foundations of physico-chemical properties that influence formulation stability especially colloïdal stability. After completing the course the student is expected to - understand the physico-chemical properties that influence formulation stability - master the basic knowledge that concern food colloidal stability - master emulsifiers properties
