Claim 7
Independent Claim
75 words
A method of making solid antifoam additive comprising the steps of a. uniformly dispersing a silicone antifoam agent in a liquid flavorant using water to make a homogeneous solution; b. mixing said solution with a crystalline sugar to form a uniform slurry; and c. dehydrating said slurry in such a manner so as to form substantially dry, homogeneous and rapidly water-soluble solid antifoam crystalline matrix wherein the final moisture content therein is 3% or less.
Claim 8
Independent Claim
75 words
A method of making solid antifoam additive comprising the steps of a. uniformly dispersing a silicone antifoam agent in a liquid flavorant using water to make a homogeneous solution; b. mixing said solution with a crystalline sugar to form a uniform slurry; and c. dehydrating said slurry in such a manner so as to form substantially dry, homogeneous and rapidly water-soluble solid antifoam crystalline matrix wherein the final moisture content therein is 3% or less.
Claim 9
Dependent Claim
20 words
A method of making solid antifoam additive in accordance with claim 6 wherein said slurry is dehydrated by vacuum drying.
Claim 10
Dependent Claim
40 words
A method of making solid antifoam additive in accordance with claim 6 wherein said silicone antifoam agent is employed in said slurry in an amount sufficient to provide from 0.1 to 3% silicone antifoamant by weight of said antifoam additive.
Claim 11
Dependent Claim
22 words
A method of making solid antifoam additive in accordance with claim 8 wherein said silicone antifoam agent comprises from 0.15 to 2%.
