The present invention relates to a two-step emulsification process for preparing a lipid and protein component-containing composition comprising large lipid globules, preferably coated with polar lipids, and to the compositions obtained thereby. Optionally, the lipid and protein component-containing composition is spray-dried. The obtained compositions are for feeding infants and young children.

Two-step emulsification process for preparing infant formula

The present invention concerns a process for manufacturing an infant formula product involving: (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 having 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 45-73 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 to obtain an extruded material; (e) preparing an infant formula product from the extruded material. The invention further concerns an 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.

Extrusion

The present invention concerns a process for manufacturing an infant formula product comprising: (a1) providing an aqueous mixture having a protein component and a carbohydrate component, (a2) subjecting the aqueous mixture to a protein hydrolysis step, (a3) subjecting the aqueous mixture to a heat treatment step; (b) mixing the heat-treated aqueous mixture comprising hydrolyzed protein with a lipid component; (c) subjecting the aqueous mixture comprising the lipid component, the carbohydrate component and the heat-treated hydrolyzed 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 to obtain an extruded material; (e) preparing an infant formula product from the extruded 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.
