Abstract
Abstract A process for preparing a flavoring agent by reaction of a monosaccharide and a plastein supplemented with a sulfur-containing amino acid in the presence of water at 80 DEG to 120 DEG C., and the product thereby obtained, as well as meat-flavored textured protein compositions having incorporated therein 0.1 to 10% by weight of the above flavoring agent.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
114 words
A process for preparing a flavoring agent which comprises reacting a mixture of one part by weight of a hexose or pentose monosaccharide and from about one to twenty parts by weight of a plastein supplemented with about 5 to 50% by weight, based on the supplemented plastein, of a sulfur-containing amino acid which is held in a state of peptide bonding to said plastein and which acid is selected from the group consisting of methionine, cysteine, cystine and lanthionine, in water as the reaction medium, the amount thereof providing at least about two parts by weight of water for each part of said supplemented plastein, at a temperature from about 80° to 120°C.
Claim 2
Dependent Claim
114 words
A process for preparing a flavoring agent which comprises reacting a mixture of one part by weight of a hexose or pentose monosaccharide and from about one to twenty parts by weight of a plastein supplemented with about 5 to 50% by weight, based on the supplemented plastein, of a sulfur-containing amino acid which is held in a state of peptide bonding to said plastein and which acid is selected from the group consisting of methionine, cysteine, cystine and lanthionine, in water as the reaction medium, the amount thereof providing at least about two parts by weight of water for each part of said supplemented plastein, at a temperature from about 80° to 120°C.
Claim 3
Dependent Claim
23 words
A process according to claim 1 wherein said hexose, or pentose monosaccharide is selected from the group consisting of glucose, ribose and arabinose.
Claim 4
Dependent Claim
23 words
A process according to claim 1, wherein the weight ratio of said monosaccharide to said supplemented plastein is from about 1:4 to 1:10.
Claim 5
Dependent Claim
13 words
A process according to claim 3, wherein said weight ratio is about 1:10.
Claim 6
Dependent Claim
18 words
A process according to claim 1 wherein monosodium glutamate is included as a flavor modifier in said mixture.
Claim 7
Dependent Claim
21 words
A process according to claim 5, wherein the weight ratio of monosodium glutamate to plastein is from about 1:1 to 1:10.
Claim 8
Dependent Claim
13 words
A process according to claim 6, wherein said weight ratio is about 1:5.
Claim 9
Dependent Claim
25 words
A process according to claim 1, wherein said monosaccharide is ribose or arabinose and the weight ratio of water to supplemented plastein is about 5:1.
Claim 10
Dependent Claim
23 words
A process according to claim 1, wherein said monosaccharide is glucose and the weight ratio of water to supplemented plastein is about 20:1.
Claim 11
Dependent Claim
27 words
A process according to claim 1, wherein the amount of said sulfur-containing amino acid is from about 15 to 20% by weight based on the supplemented plastein.
Claim 12
Dependent Claim
42 words
A process according to claim 1, wherein the source of said sulfur-containing amino acid employed in supplementing said plastein is an alkyl ester or alkyl ester salt of said sulfur-containing amino acid; said alkyl having from about one to four carbon atoms.
Claim 13
Dependent Claim
10 words
A flavoring agent prepared by the process of claim 1.
Claim 14
Dependent Claim
34 words
A meat-flavored textured protein composition comprising a textured protein having incorporated therein from about 0.1 to 10% by weight based on the dry weight of textured protein, of said flavoring agent of claim 12.
Claim 15
Dependent Claim
34 words
A meat-flavored textured protein composition comprising a textured protein having incorporated therein from about 0.75 to 6% by weight based on the dry weight of textured protein, of said flavoring agent of claim 12.
Claim 16
Dependent Claim
44 words
A meat-flavored textured protein composition according to claim 13, wherein after said flavoring agent is incorporated, the mixture is extruded at a pressure of from about 300-3000 pounds per square inch and at a temperature in the range of about 100° to 150° C.
Claim 17
Dependent Claim
