The present invention relates to a process for preparing an infant formula product comprising lipid globules having a volume weighted mode diameter of at least 1.0 [mu] m wherein the process comprises: (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 to obtain an oil-in-water emulsion having a total solids content of 45-80% by weight; (d) delivering the homogenized emulsion to an extruder, independently adding digestible carbohydrates and optionally dietary fibers to the extruder, and extruding the contents of the extruder to obtain an extruded material; (e) preparing an infant formula product from the extruded material wherein step (e) comprises a step of drying the extruded material wherein the drying may be selected from the group consisting of rapid drying, vacuum drying, belt drying, microwave drying, infrared drying and spray drying, with the proviso that the spray drying uses an atom
