Abstract
Abstract Aqueous solutions containing dissolved cheese whey protein exhibiting improved whipping properties are obtained by heating the solution to within the range of at least 90 DEG C. to less than 99 DEG C., thereafter cooling the solution to less than 60 DEG C., and whipping the solution within about 8 hours after heating. The process is particularly effective with protein solutions derived from cheese whey protein concentrates.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A process for improving the whipping properties of an aqueous solution containing dissolved cheese whey protein consisting essentially of a. heating an aqueous solution containing dissolved cheese whey protein having a protein concentration of about 5 grams per liter to about 100 grams per liter to a temperature within the range of at least 95°C. to less than 99° C. said aqueous solution being heated to a temperature within said range for not more than 5 minutes; b. cooling said aqueous solution containing dissolved cheese whey protein to below about 60° C.; and c. whipping said aqueous solution containing dissolved cheese whey protein within about 8 hours after heating.
Claim 2
Dependent Claim
109 words
A process for improving the whipping properties of an aqueous solution containing dissolved cheese whey protein consisting essentially of a. heating an aqueous solution containing dissolved cheese whey protein having a protein concentration of about 5 grams per liter to about 100 grams per liter to a temperature within the range of at least 95°C. to less than 99° C. said aqueous solution being heated to a temperature within said range for not more than 5 minutes; b. cooling said aqueous solution containing dissolved cheese whey protein to below about 60° C.; and c. whipping said aqueous solution containing dissolved cheese whey protein within about 8 hours after heating.
Claim 3
Dependent Claim
15 words
The process of claim 1 wherein said cheese whey protein is sweet cheese whey protein.
Claim 4
Dependent Claim
33 words
The process of claim 2 wherein said sweet cheese whey protein is selected from the group consisting of cheddar cheese whey proetein, Swiss cheese whey protein, mozzarella cheese whey protein, and mixtures thereof.
Claim 5
Dependent Claim
30 words
The process of claim 1 wherein said cheese whey protein is derived from partially delactosed/demineralized cheese whey having a protein concentration between about 14% to about 90% (dry weight basis).
Claim 6
Dependent Claim
31 words
The process of claim 1 which further includes the step of incorporating flavoring ingredients in said whipped aqueous solution containing dissolved protein, said ingredient being added before, during or after whipping.
Claim 7
Dependent Claim
54 words
The process of claim 1 which further includes the step of adding a food grade citrate selected from the group consisting of potassium citrate, sodium citrate, or mixtures thereof to said aqueous solution containing dissolved protein at a concentration of about 0.1 gram per liter to about 5 grams per liter prior to heating.
Claim 8
Dependent Claim
56 words
The process of claim 2 wherein said cheese whey protein is selected from the group consisting of cheddar cheese whey protein, Swiss cheese whey protein, mozzarella cheese whey protein, or derived from partially delactosed/demineralized cheese whey having a protein concentration within the range of from about 14% to about 90% (dry weight basis), or mixtures thereof.
Claim 9
Dependent Claim
54 words
The process of claim 1 which further includes the step of adding a food grade citrate selected from the group consisting of potassium citrate, sodium citrate, or mixtures thereof to said aqueous solution containing dissolved protein at a concentration of about 0.1 gram per liter to about 5 grams per liter prior to heating.
Claim 10
Dependent Claim
8 words
