Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
25 words
A rapidly dissolvable and substantially dry antifoam additive for dry beverage compositions comprising a uniform crystalline matrix of crystalline sugar, flavorant and silicone antifoam agent.
Claim 2
Dependent Claim
25 words
A rapidly dissolvable and substantially dry antifoam additive for dry beverage compositions comprising a uniform crystalline matrix of crystalline sugar, flavorant and silicone antifoam agent.
Claim 3
Dependent Claim
24 words
An antifoam additive in accordance with claim 1 wherein said silicone antifoam agent comprises from 0.1 to 3% by weight of said antifoam additive.
Claim 4
Dependent Claim
22 words
An antifoam additive in accordance with claim 1 wherein said flavorant comprises from 0.2 to 10% by weight of said antifoam additive.
Claim 5
Dependent Claim
22 words

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%.
Claim 12
Dependent Claim
37 words
A method of making solid antifoam additive in accordance with claim 6 wherein said flavorant is employed in said slurry in an amount sufficient to provide from 0.2 to 10% flavorant by weight of said antifoam additive.
Claim 13
Dependent Claim
20 words
A method of making solid antifoam additive in accordance with claim 10 wherein said flavorant comprises from 1 to 5%.
Claim 14
Dependent Claim
19 words
A method of making solid antifoam additive in accordance with claim 6 wherein said flavorant is a cola-base material.
Claim 15
Dependent Claim
18 words
A method of making solid antifoam additive in accordance with claim 6 wherein said crystalline sugar is sucrose.
Claim 16
Dependent Claim
48 words
A substantially dry rapidly-dissolvable beverage mix suitable for the preparation of a potable beverage upon dissolution in water and free from excessive foaming tendencies comprising a dry beverage mix and an effective amount of a substantially dry crystalline antifoam matrix of crystalline sugar, flavorant and silicone antifoam agent.
Claim 17
Dependent Claim
48 words
A substantially dry rapidly-dissolvable beverage mix suitable for the preparation of a potable beverage upon dissolution in water and free from excessive foaming tendencies comprising a dry beverage mix and an effective amount of a substantially dry crystalline antifoam matrix of crystalline sugar, flavorant and silicone antifoam agent.
Claim 18
Dependent Claim
22 words
A substantially dry rapidly-dissolvable beverage mix in accordance with claim 14 wherein said beverage mix and said antifoam matrix are cola-based materials.
