Abstract
Abstract Bland soy protein is produced by suspending soy protein in a fluid medium and adjusting the pH thereof to between 1.5 and 4.0. An Acid Fungal Protease is added to the acidified suspension and allowed to act on the suspension at temperatures up to 55*C. The protein becomes bland and is spray dried to a powder.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
A METHOD OF PRODUCING A BLAND SOY PROTEIN CONSISTING ESSENTIALLY OF SUSPENDING SOY PROTEIN IN AN AQUEOUS MEDIUM, ADJUSTING THE PH OF THE RESULTING SUSPENSION TO BETWEEN ABOUT 1,5 AND 4.0, ADDING TO THE SUSPENSION AN ACID FUNGAL PROTEASE, ALLOWING THE ACID FUNGAL PROTEASE TO ACT ON THE SUSPENSIONN AT TEMPERATURE O FROM 40*C UP TO ABOUT 550C UNTIL A BLAND PROTEIN IS PRODUCED, AND ESSENTIALLY NEUTRALIZING THE SUSPENSION TO ADJUSTING THE PH TO 6 TO 8.
Claim 2
Independent Claim
77 words
A METHOD OF PRODUCING A BLAND SOY PROTEIN CONSISTING ESSENTIALLY OF SUSPENDING SOY PROTEIN IN AN AQUEOUS MEDIUM, ADJUSTING THE PH OF THE RESULTING SUSPENSION TO BETWEEN ABOUT 1,5 AND 4.0, ADDING TO THE SUSPENSION AN ACID FUNGAL PROTEASE, ALLOWING THE ACID FUNGAL PROTEASE TO ACT ON THE SUSPENSIONN AT TEMPERATURE O FROM 40*C UP TO ABOUT 550C UNTIL A BLAND PROTEIN IS PRODUCED, AND ESSENTIALLY NEUTRALIZING THE SUSPENSION TO ADJUSTING THE PH TO 6 TO 8.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein the amount of soy protein suspended in the fluid medium is less than about 30% by weight of the fluid medium.
Claim 4
Dependent Claim
28 words
The method of claim 2 wherein the amount of soy protein suspended in the fluid medium is between about 1% and 20% by weight of the fluid medium.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein the aqueous medium is water.
Claim 6
Dependent Claim
28 words
The method of claim 1 wherein the amount of enzyme added to the suspension is between 1 and 30% by weight of the soy protein in the suspension.
Claim 7
Dependent Claim
11 words
The method of claim 5 wherein the neutralized suspension is dried.
Claim 8
Dependent Claim
11 words
The method of claim 6 wherein the suspension is spray dried.
Claim 9
Dependent Claim
25 words
The method of claim 1 wherein the suspension is adjusted to a pH of between 6 and 8, after the bland soy protein is produced.
Claim 10
Dependent Claim
22 words
A dried soy protein powder which is biologically altered by action of an exzyme consisting essentially of an Acid Fungal Protease enzyme.
Claim 11
Dependent Claim
22 words
A dried soy protein powder which is biologically altered by action of an exzyme consisting essentially of an Acid Fungal Protease enzyme.
Claim 12
Dependent Claim
14 words
A food composition containing a portion of the soy protein powder of claim 9.
