Abstract
Abstract Non-dairy coffee whiteners can be provided with stability to the thermal and acid stresses of coffee by incorporating a water-soluble acetate salt in the whitener. The acetate salt may be used as a total or partial replacement of conventional stabilizing salts generally used in whiteners. Acetate salts which may be used include sodium acetate, potassium acetate, calcium acetate and mixtures thereof, and may be added to the whitener as such or formed in situ during the preparation of the whitener.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
60 words
In a non-dairy coffee whitener containing fat, protein, carbohydrate, emulsifier and an amount of stabilizing salt sufficient to stabilize the whitener to the thermal and acid stresses of coffee without imparting an undesirable taste or flavor to the whitener, the improvement wherein at least a portion of the stabilizing salt is an effective amount of a water soluble acetate salt.
Claim 2
Dependent Claim
60 words
In a non-dairy coffee whitener containing fat, protein, carbohydrate, emulsifier and an amount of stabilizing salt sufficient to stabilize the whitener to the thermal and acid stresses of coffee without imparting an undesirable taste or flavor to the whitener, the improvement wherein at least a portion of the stabilizing salt is an effective amount of a water soluble acetate salt.
Claim 3
Dependent Claim
28 words
The coffee whitener defined in claim 1 in which the acetate salt is selected from the group consisting of sodium acetate, potassium acetate, calcium acetate and mixtures thereof.
Claim 4
Dependent Claim
20 words
The coffee whitener defined in claim 2 in which the acetate salt is the sole stabilizing salt in the whitener.
Claim 5
Dependent Claim
32 words
The coffee whitener defined in claim 3 in which the whitener is in liquid or frozen form and the acetate salt comprises from about 0.1% to 1.5% by weight of the whitener.
Claim 6
Dependent Claim
30 words
The coffee whitener defined in claim 3 in which the whitener is in powdered form and the acetate salt comprises from about 0.5% to 3% by weight of the whitener.
Claim 7
Dependent Claim
42 words
The coffee whitener defined in claim 2 in which the stabilizing salt comprises a combination of the acetate salt and a salt selected from the group consisting of mono- and dipotassium phosphate, disodium phosphate, tetrasodium pyrophosphate, sodium aluminum phosphate and sodium citrate.
Claim 8
Dependent Claim
91 words
The coffee whitener defined in claim 1 in which the whitener is in liquid or frozen form and comprises from 3% to 18% by wt. of fat, from 1% to 3% by wt. of protein, from 2.5% to 15% by wt. of carbohydrate, from 0.3% to 1.0% by weight of emulsifier and from 0.1% to 1.5% by weight of stabilizing salt, at least a portion of said stabilizing salt comprising an effective amount of acetate salt selected from the group consisting of sodium acetate, potassium acetate, calcium acetate and mixtures thereof.
Claim 9
Dependent Claim
83 words
The coffee whitener defined in claim 1 in which the whitener is in powdered form and comprises from 25% to 50% by weight fat, from 3% to 12% by weight protein, from 35% to 65% by weight carbohydrate, from 1% to 5% by weight emulsifier and from 0.5% to 3% by weight of stabilizing salt at least a portion of which is an effective amount of acetate salt selected from the group consisting of sodium acetate, potassium acetate, calcium acetate and mixtures thereof.
Claim 10
Dependent Claim
80 words
In a method of preparing a non-dairy coffee whitener having stability to the thermal and acid stresses of coffee by forming an aqueous emulsion containing fat, protein, carbohydrate, emulsifier and stabilizing salt, the improvement which comprises including in the aqueous emulsion as the stabilizing salt, an effective amount of a water soluble acetate salt selected from the group consisting of sodium acetate, potassium acetate, calcium acetate and mixtures thereof, alone or in combination with a phosphate or a citrate salt.
Claim 11
Dependent Claim
80 words
In a method of preparing a non-dairy coffee whitener having stability to the thermal and acid stresses of coffee by forming an aqueous emulsion containing fat, protein, carbohydrate, emulsifier and stabilizing salt, the improvement which comprises including in the aqueous emulsion as the stabilizing salt, an effective amount of a water soluble acetate salt selected from the group consisting of sodium acetate, potassium acetate, calcium acetate and mixtures thereof, alone or in combination with a phosphate or a citrate salt.
Claim 12
Dependent Claim
47 words
The method defined in claim 9 in which the acetate salt is the sole stabilizing salt in emulsion and is present in an amount sufficient to stabilize the whitener to the thermal and acid stresses of coffee without imparting an undesirable taste or flavor to the whitener.
Claim 13
Dependent Claim
22 words
The method defined in claim 10 in which the aqueous emulsion contains from 0.1% to 1.5% by weight of said acetate salt.
Claim 14
Dependent Claim
31 words
The method defined in claim 10 in which the aqueous emulsion is dried to provide a powdered coffee whitener which contains from 0.5% to 3% by weight of the acetate salt.
Claim 15
Dependent Claim
41 words
The method defined in claim 9 in which acetic acid and a base selected from the group consisting of hydroxides and carbonates of sodium, potassium and calcium are added to the aqueous emulsion to form the acetate stabilizing salt in situ.
