Food composition comprising gas bubbles and process for preparing it

A process to prepare a food composition, the food composition comprising gas bubbles and, based on the food composition;

• at least 10 wt. % of water,
• optionally fat, wherein the amount of fat and water taken together is at least 60 wt. % and less than 99 wt. %,
• at least 1 vol. % and less than 70 vol. % of gas,
• fibre particles having an insoluble particulate structure, a length of 0.1 to 100 microns and aspect ratio more than 10,
• surface active particles having a volume weighted mean diameter is at least 0.1 μm and less than 10 μm and selected from the group consisting of water insoluble methyl cellulose, and ethyl cellulose,
• wherein 2 times the volume weighted mean diameter of the surface active particles (d2) is smaller than the length of the fibre particles (L) and wherein the fibre particles are present together with the surface active particles at the air-water interface and attract each other and wherein the gas bubbles are stable against disproportionation for at least 3 weeks at ambient and chilled conditions, the process comprising the steps of:
• a. incorporating in a liquid food composition
• surface active particles
• fibre particles
• b. incorporating gas in said liquid food composition
• c. packing the food composition, and
• wherein any fat, protein and thickening agent to be included in the food composition, is included after step b and before step c.
