Abstract
Abstract An acidified protein beverage rich in nutritional polypeptide value is prepared by (1) forming a slurry of edible protein in water, (2) subjecting said slurry to a pre-hydrolysis, denaturation heat treatment, (3) subjecting said preheated slurry to the hydrolytic action of a proteolytic enzyme to produce water soluble polypeptides, (4) adjusting the pH of the solution to in the range of from about 2.5 to about 6.0 and (5) formulating the solubilized polypeptides into a beverage.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A PROCESS OF MAKING AN ACIDIC, AQUEOUS SOLUTION OF POLYPEPTIDES FOR USE AS A BASE IN PREPARING AN ACIDIC, PROTEIN BEVERAGE, COMPRISING (A) HEATING AN AQUEOUS SLURRY OF A DEFATTED PROTEIN SELECTED FROM THE GROUP CONSISTING OF SOYA, COTTON OR CORN SEEDS AT A TEMPERATURE OF FROM ABOUT 150* TO 375*F. FOR A TIME SUFFICIENT TO INCREASE THE YIELD OF A SOLUBLE, NITRITIONAL, POLYPEPTIDE PRODUCT WHICH IS PRODUCED WHEN THE HEATED SLURRY IS SUBSEQUENTLY SUBJECTED TO ENZYMATIC HYDROLYSIS, BUT INSUFFICIENT TO DELETERIOUSLY AFFECT THE FLAVOR OF SAID POLYPEPTIDE PRODUCT, (B) SUBJECTING THE RESULTING SLURRY TO ENZYMATIC HYDROLYIS CONDITIONS INCLUDING THE ACTION OF A PROTEOLYTIC ENZYME TO PRODUCE POLYPEPTIDES, (C) ADJUSTING THE PH OF THE RESULTING SLURRY TO WITHIN THE RANGE OF FROM ABOUT 2.5 TO 6.0, AND (D) REMOVING PRECIPITATED MATERIAL FROM THE SLURRY TO LEAVE A CLEAR, ACIDIC SOLUTION OF POLYPEPTIDES SUITABLE FOR USE AS A BASE IN PREPARING AN ACIDIC, PROTEIN BEVERAGE.

The process of claim 1 wherein the protein used is defatted soya protein.
Claim 4
Dependent Claim
21 words
The process of claim 1 wherein the aqueous slurry of defatted protein is heated for from about 0.01 to 120 seconds.
Claim 5
Dependent Claim
29 words
The process of claim 1 wherein the enzymatic hydrolyis conditions include a temperature of from about 105* to 150F. and a residence time of about 30 to 150 minutes.
Claim 6
Dependent Claim
12 words

Claim 7
Dependent Claim
97 words
A process of making an acidic, carbonated protein beverage from defatted soya protein, comprising heating an aqueous slurry of the defatted soya protein at a temperature of from about 150* to 375*F. for about 0.01 to 120 seconds, subjecting the resulting slurry to enzymatic hydrolyis conditions including the action of a proteolytic enzyme to produce polypepetides, adjusting the pH of the resulting slurry to within the range of from about 3.0 to 4.0, removing precipitated material from the acidified slurry to leave a clear, acidic solution of polypeptides, and formulating the solution into an acidic, carbonated beverage.
Claim 8
Dependent Claim
97 words
A process of making an acidic, carbonated protein beverage from defatted soya protein, comprising heating an aqueous slurry of the defatted soya protein at a temperature of from about 150* to 375*F. for about 0.01 to 120 seconds, subjecting the resulting slurry to enzymatic hydrolyis conditions including the action of a proteolytic enzyme to produce polypepetides, adjusting the pH of the resulting slurry to within the range of from about 3.0 to 4.0, removing precipitated material from the acidified slurry to leave a clear, acidic solution of polypeptides, and formulating the solution into an acidic, carbonated beverage.
Claim 9
Dependent Claim
19 words
The process of claim 6 wherein the soya protein is in the form of soya flour or soya grits.
Claim 10
Dependent Claim
19 words
The process of claim 7 wherein the slurry is heated at a temperature of from about 200* to 265F.
Claim 11
Dependent Claim
36 words
