Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A process for making a freeze-thaw stable, edible foam comprising the steps of: (a) adding a dairy ingredient comprising milk fat to a mixing vessel; (b) adding a food approved, calcium chelating salt to the mixing vessel, wherein said salt: (i) is essentially free of calcium; (ii) is the salt of a phosphorous oxyacid; (iii) has a pK a between 2 and about 9; (iv) the amount of said salt added is between about 0.001% and about 1% of the total ingredients in the mixing vessel, by weight, and said amount of chelating salt is effective to impart freeze-thaw stability to the foam; (c) solubilizing and dispersing the ingredients within said mixing vessels; (d) homogenizing said solubilized and dispersed ingredients at a pressure of at least 6000 p.s.i.g. so as to form an emulsion; and (e) whipping and aerating said emulsion to an overrun of at least about 150% by volume.
