Beschreibung
Zusammenfassung:	The present invention concerns a process for manufacturing an infant formula product comprising: (a) subjecting an aqueous mixture having a protein component and a carbohydrate component to a heat treatment step; (b) mixing the aqueous mixture with a lipid component; (c) subjecting the aqueous mixture comprising the lipid component, the carbohydrate component and the heat-treated protein component to a homogenization and emulsification step to obtain a homogenized oil-in-water emulsion having a total solids content in the range of 45-80 wt %; (d) conveying the homogenized emulsion into an extruder, independently adding digestible carbohydrates and optionally dietary fibres to the extruder and extruding the contents of the extruder wherein a gas is injected into the extruder, to obtain an extruded aerated material (e) preparing an infant formula product from the extruded aerated material. The invention further concerns Infant formula product obtainable by the process according to the invention and to a modular system suitable for performing the process according to the invention.
