Abstract
Abstract An effervescent ice confection product is obtained by exposing CO 2 - water clathrate-containing particles to such pressure, temperature and CO 2 and water partial pressure conditions that a protective layer will be formed on the particles, mixing said particles with a liquid phase containing ice confection ingredients and usually solid ice and having a temperature such that frozen water will not melt therein and thereafter decreasing the temperature of the obtained mixture to a usual storage temperature.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
140 words
A method for preparing a carbonated ice confection product comprising the steps of: (a) preparing a flavored ice confection fluid phase, (b) cooling the fluid phase such that a partially frozen slurry is obtained, (c) contacting CO 2 with water under pressure at a cooling temperature such that a solid CO 2 clathrate ice composite forms, (d) grinding the solid clathrate-ice composite to obtain CO 2 clathrate-ice composite particles, (e) exposing the CO 2 clathrate-ice composite particles to CO 2 , moisture, temperature and pressure conditions for a period of time sufficient to allow a protective coating to form on the surface of the clathrate particles which prevents loss of CO 2 from the clathrate particles, (f) mixing the partially frozen slurry and the coated clathrate particles; and (g) further freezing the mixture to form a carbonated ice confection product.
Claim 2
Independent Claim
