Abstract
Abstract Oleaginous protein is first converted to acid soluble polypeptides by hydrolysis with a proteolytic enzyme. The hydrolyzate is then acylated to produce an acid soluble protein concentrate having a bland flavor and substantially no objectionable odor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
42 words
Method for producing a modified proteinaceous food having mild flavor comprising the steps of first hydrolyzing protein obtained from oleaginous seeds with a proteolytic enzyme to form an acid soluble polypeptide mixture, and then acylating said mixture to form an acylated hydrolyzate.
Claim 2
Dependent Claim
42 words
Method for producing a modified proteinaceous food having mild flavor comprising the steps of first hydrolyzing protein obtained from oleaginous seeds with a proteolytic enzyme to form an acid soluble polypeptide mixture, and then acylating said mixture to form an acylated hydrolyzate.
Claim 3
Dependent Claim
12 words
The method according to claim 1 wherein the protein is soy protein.
Claim 4
Dependent Claim
25 words
The method according to claim 1 wherein said acylated hydrolyzate is soluble in acid solutions having a pH of from about 2 to about 6.
Claim 5
Dependent Claim
9 words
The product obtained from the process of claim 1.
Claim 6
Dependent Claim
9 words
An acidic beverage containing the product of claim 1.
Claim 7
Dependent Claim
10 words
The beverage of claim 5 wherein said beverage is carbonated.
Claim 8
Dependent Claim
64 words
Method for producing a modified proteinaceous food having mild flavor comprising the steps of first hydrolyzing protein obtained from oleaginous seeds with a proteolytic enzyme to form an acid soluble polypeptide mixture, said protein being selected from the group consisting of protein derived from soy, peanut, cotton seed, corn, rape, sesame and mixtures thereof, and then acylating said mixture to form an acylated hydrolyzate.
Claim 9
Dependent Claim
64 words
Method for producing a modified proteinaceous food having mild flavor comprising the steps of first hydrolyzing protein obtained from oleaginous seeds with a proteolytic enzyme to form an acid soluble polypeptide mixture, said protein being selected from the group consisting of protein derived from soy, peanut, cotton seed, corn, rape, sesame and mixtures thereof, and then acylating said mixture to form an acylated hydrolyzate.
Claim 10
Dependent Claim
13 words
The method of claim 7 wherein said mixture is acylated with succinic anhydride.
