• Context of sustainable development
and growing interest in alternative proteins

Modification of functional properties and digestibility of infant formulas
• Importance of protein nutritional quality:
o Infant optimal growth
(Michaelsen & Greer, 2014)(Friedman, 1996)
o Essential amino acid content and digestibility

↓ functional properties and digestibility of infant formulas
Research question:
How protein sources influence the functional properties
and the digestibility of infant formulas ?
STLOpen Days 19-21 March 2019
