Abstract
Abstract Turbid protein fortified citrus flavored soft drinks can be prepared by adding to the soft drink a protein fortifier of either cheese whey protein concentrate when the final pH of the soft drink is within the range of pH 3.1 to 3.9 or a combination of 50%-95% cheese whey protein concentrate and about 50-5% non-fat dried milk when the pH of the final drink is within the range of from 3.1 to 3.7.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
174 words
A method for fortifying liquid acidic soft drinks having a pH within the range of from about 3.1 to about 3.7 with protein while providing a turbid stable suspension therein which does not settle after one month having from about 67% to about 16% light transmittance as measured by a Beckman Spectrophotometer Model DB-G at wave length 640 nm which comprises admixing with said acidic soft drink a protein fortifier composition comprising from about 50% to about 95% of cheese whey protein concentrate having a protein solids concentration between about 25% and about 60% by weight on a dry basis prepared by ultrafiltration of acid cheese whey in combination with from about 5% to about 50% high heat non-fat dried milk , said protein fortifier being admixed in an amount sufficient to add from about 0.1% to about 5% by weight protein based on the total weight of the soft drink, said percentages unless otherwise stated being by weight based on the combined dry weight of said protein concentrate and said non-fat dried milk.
Claim 2
Independent Claim
174 words
A method for fortifying liquid acidic soft drinks having a pH within the range of from about 3.1 to about 3.7 with protein while providing a turbid stable suspension therein which does not settle after one month having from about 67% to about 16% light transmittance as measured by a Beckman Spectrophotometer Model DB-G at wave length 640 nm which comprises admixing with said acidic soft drink a protein fortifier composition comprising from about 50% to about 95% of cheese whey protein concentrate having a protein solids concentration between about 25% and about 60% by weight on a dry basis prepared by ultrafiltration of acid cheese whey in combination with from about 5% to about 50% high heat non-fat dried milk , said protein fortifier being admixed in an amount sufficient to add from about 0.1% to about 5% by weight protein based on the total weight of the soft drink, said percentages unless otherwise stated being by weight based on the combined dry weight of said protein concentrate and said non-fat dried milk.
Claim 3
Dependent Claim
32 words
The method as recited in claim 1 wherein the pH of said acid soft drink admixed with said protein fortifier composition is within the range of from about 3.2 to about 3.5.
Claim 4
Dependent Claim
13 words
The method as recited in claim 2 wherein said pH is about 3.5±0.05.
Claim 5
Dependent Claim
24 words
The method as recited in claim 1 wherein the whey protein concentrate has a protein concentration of between about 40 and 60% by weight.
Claim 6
Dependent Claim
37 words
The method as recited in claim 1 wherein said composition is comprised of from about 75% to about 90% of said cheese whey protein concentrate and from about 10% to about 25% of said non-fat dried milk.
Claim 7
Dependent Claim
17 words
The method as recited in claim 1 wherein said acidic soft drink is a carbonated citrus drink.
Claim 8
Dependent Claim
8 words
The product of the method of claim 1.
Claim 9
Dependent Claim
120 words
A protein fortifier composition for providing liquid acidic soft drinks having a final protein fortification and a turbid stable suspension therein which does not settle after one month having from about 67% to about 16% light transmittance as measured by a Beckman Spectrophotometer Model DB-G at wave length 640 nm comprising from about 50% to about 95% cheese whey protein concentrate having a protein solids concentration between about 25% and 60% by weight on a dry basis prepared by the ultrafiltration of acid cheese whey and from about 50% to about 5% high heat non-fat dried milk, said percentages unless otherwise stated being by weight based on the combined dry weight of the protein concentrate and the non-fat dried milk.
Claim 10
Dependent Claim
120 words
A protein fortifier composition for providing liquid acidic soft drinks having a final protein fortification and a turbid stable suspension therein which does not settle after one month having from about 67% to about 16% light transmittance as measured by a Beckman Spectrophotometer Model DB-G at wave length 640 nm comprising from about 50% to about 95% cheese whey protein concentrate having a protein solids concentration between about 25% and 60% by weight on a dry basis prepared by the ultrafiltration of acid cheese whey and from about 50% to about 5% high heat non-fat dried milk, said percentages unless otherwise stated being by weight based on the combined dry weight of the protein concentrate and the non-fat dried milk.
Claim 11
Dependent Claim
44 words
The protein fortifier composition as recited in claim 8 wherein said cheese whey protein concentrate is present in an amount ranging from about 75% to about 90% and said non-fat dried milk is present in an amount ranging from about 10% to about 25%.
Claim 12
Dependent Claim
28 words
The protein fortifier composition as recited in claim 8 wherein said whey protein concentrate has a whey protein concentration ranging from about 40% to about 60% by weight.
Claim 13
Dependent Claim
27 words
The protein fortifier composition is recited in claim 8 wherein said acid cheese whey prior to concentration by ultrafiltration is a neutralized and pasteurized cottage cheese whey.
