Abstract
Abstract Process for making ready-to-eat breakfast cereal containing soy protein. Soy protein is made more palatable by subjecting it to a partial hydrolysis reaction in the presence of a specific mixture of proteolytic enzymes. A mixture of proteolytic enzyme papain and at least one other proteolytic enzyme has the effect of more efficiently causing the partial hydrolysis of soy protein than does a single enzyme at the same addition level.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
26 words
The process of claim 1 wherein the proteolytic enzyme is selected from the group consisting of pepsin, bromelin, ficin, alcalase, maxitase, thermoase, pronase, and mixtures thereof.
Claim 2
Dependent Claim
25 words
The process of claim 1 wherein the soy protein is selected from the group consisting of soy flour, soy protein concentrate, and soy protein isolate.
Claim 3
Dependent Claim
106 words
A process for making a palatable ready-to-eat breakfast cereal having a protein content of at least 20 percent comprising: a. reacting soy protein with water in the presence of from about 15 ppm to about 2,500 ppm of papain and from about 5 ppm to about 2,500 ppm of at least one other proteolytic enzyme for 1 minute to 120 minutes at 80*F to 160*F, thereby causing a partial hydrolysis of the soy protein; b. extruding the partially hydrolyzed soy protein into strands of a desired shape; c. slicing the strands into pellet-like particles; and d. puffing the pellet-like particles to form the ready-to-eat breakfast cereal.
Claim 4
Dependent Claim
23 words
The process of claim 4 further comprising blending a gelatinized cereal grain with the partially hydrolyzed soy protein prior to the extruding step.
Claim 5
Dependent Claim
26 words
The process of claim 5 wHerein the proteolytic enzyme is selected from the group consisting of pepsin, bromelin, ficin, alcalase, maxitase, thermoase, pronase, and mixtures thereof.
Claim 6
Dependent Claim
12 words
The process of claim 6 wherein the gelatinized cereal grain is corn.
Claim 7
Dependent Claim
14 words
The process of claim 7 further comprising flaking the pellet-like particles prior to puffing.
Claim 8
Dependent Claim
34 words
The process of claim 4 wherein the papain and at least one other proteolytic enzyme are each present in an amount ranging from 100 ppm to 300 ppm by weight of the soy protein.
Claim 9
Dependent Claim
24 words
The process of claim 9 wherein the soy protein is reacted with the water at 120*F to 130*F for 1 minute to 5 minutes.
Claim 10
Dependent Claim
85 words
A process for making a palatable ready-to-eat breakfast cereal having a protein content of at least 20 percent comprising: a. reacting soy protein with water in the presence of from about 15 ppm to about 2500 ppm of papain and from about 5 ppm to about 2500 ppm of another proteolytic enzyme for 1 minute to 120 minutes at 80*F to 160*F, thereby causing a partial hydrolysis of the soy protein; and b. extruding-puffing the partially hydrolyzed soy protein to form the ready-to-eat breakfast cereal.
Claim 11
Dependent Claim
34 words
The process of claim 11 wherein 15 ppm-2500 ppm of the papain and 5 ppm-2500 ppm of at least one other proteolytic enzyme by weight of the soy protein are present in the reaction.
Claim 12
Dependent Claim
29 words
The process of claim 11 wherein the partially hydrolyzed soy protein is extruded-puffed under a pressure of 500 psig - 1000 psig and a temperature of 280*F - 320*F.
Claim 13
Dependent Claim
23 words
The process of claim 13 further comprising blending a gelatinized cereal grain with the partially hydrolyzed soy protein prior to the extruding-puffing step.
Claim 14
Dependent Claim
26 words
The process of claim 14 wherein the proteolytic enzyme is selected from the group consisting of pepsin, bromelin, ficin, alcalase, maxitase, thermoase, pronase, and mixtures thereof.
Claim 15
Dependent Claim
12 words
The process of claim 15 wherein the gelatinized cereal grain is corn.
