Patent ID: 8647695

Claim:
A method for production of an aerated food product, comprising the steps of: a) dispersing water-insoluble solid particles comprising ethylcellulose and/or a lipid material in an aqueous composition, wherein the particles have a volume weighted mean diameter between 30 nanometer and 10 micrometer, to create a dispersion; b) introduction of gas bubbles to the aqueous composition of step a) to create a foam; and wherein after step a) aggregated protein particles are mixed into the dispersion, and/or wherein after step b) aggregated protein particles are mixed into the foam, and wherein the aggregated protein particles are obtain able by a method for preparation of aggregated protein particles, comprising the steps: c) dissolving or dispersing a protein in an aqueous solution at a concentration between 4% and 15% by weight; d) aggregating the proteins in the aqueous solution into aggregated protein particles which are not surface active and have a volume weighted mean diameter between 200 nanometer and 20 micrometer; e) separating the aggregated protein particles from non-aggregated protein, and wherein an aqueous dispersion of the aggregated protein particles at a concentration of 1% by weight at 25° C. has a surface tension of at least 60 mN−m 1 .
