Abstract
Abstract A proteinaceous foodstuff comprising an edible sulfur-containing amino acid deficient protein and a nutritionally supplemental amount of a sulfur-containing amino acid derivative selected from the group consisting of N-acyl L-methionine ester, N,N'-diacyl L-cystine ester and N-acyl L-cysteine ester, wherein the acyl group is derived from fatty acids having from 1 to 9 carbon atoms, and the ester group is derived from fatty alcohols having from 1 to 22 carbon atoms.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
70 words
A proteinaceous foodstuff comprising an edible sulfur-containing amino acid deficient protein and a nutritionally supplemental amount of a sulfur-containing amino acid derivative selected from the group consisting of N-acyl L-methionine ester, N,N'-diacyl L-cystine ester and N-acyl L-cysteine ester, wherein the acyl group is derived from fatty acids having from 1 to 9 carbon atoms, and the ester group is derived from fatty alcohols having from 1 to 22 carbon atoms.
Claim 2
Dependent Claim
70 words
A proteinaceous foodstuff comprising an edible sulfur-containing amino acid deficient protein and a nutritionally supplemental amount of a sulfur-containing amino acid derivative selected from the group consisting of N-acyl L-methionine ester, N,N'-diacyl L-cystine ester and N-acyl L-cysteine ester, wherein the acyl group is derived from fatty acids having from 1 to 9 carbon atoms, and the ester group is derived from fatty alcohols having from 1 to 22 carbon atoms.
Claim 3
Dependent Claim
30 words
The foodstuff of claim 1 where said foodstuff is derived from a member selected from the group consisting of: animal by-products, microbial cells, oil seeds, cereal grains and plant vegetation.
Claim 4
Dependent Claim
36 words
The foodstuff of claim 1 wherein the foodstuff is selected from the group consisting of: texturized vegetable protein meat analogs, vegetable protein derived cheese analogs, beverages, nut butters, breakfast-like cereal formulations, and convenient proteinaceous snack foods.
Claim 5
Dependent Claim
14 words
The foodstuff of claim 1 where the sulfur-containing amino acid derivative is N-acyl-L-methionine ester.
Claim 6
Dependent Claim
37 words
The foodstuff of claim 4 where the acyl group is derived from fatty acids having from 1 to 4 carbon atoms and the ester group is derived from fatty alcohols having from 1 to 10 carbon atoms.
Claim 7
Dependent Claim
21 words
The foodstuff of claim 5 where the ester group is derived from fatty alcohols having from 1 to 4 carbon atoms.
Claim 8
Dependent Claim
32 words
The foodstuff of claim 6 wherein the derivative is selected from the group consisting of N-formyl L-methionine methyl ester, N-formyl L-methionine ethyl ester, N-acetyl L-methionine methyl ester and N-acetyl L-methionine ethyl ester.
Claim 9
Independent Claim
72 words
A method of fortifying proteinaceous foodstuffs with sulfur-containing amino acids comprising adding to said foodstuffs a nutritionally effective amount of an amino acid derivative selected from the group consisting of N-acyl L-methionine ester, N,N'-diacyl L-cystine ester and N-acyl L-cysteine ester, wherein the acyl group is derived from fatty acids having from 1 to 9 carbon atoms, and the ester group is derived from fatty alcohols having from 1 to 22 carbon atoms.
Claim 10
Independent Claim
72 words
A method of fortifying proteinaceous foodstuffs with sulfur-containing amino acids comprising adding to said foodstuffs a nutritionally effective amount of an amino acid derivative selected from the group consisting of N-acyl L-methionine ester, N,N'-diacyl L-cystine ester and N-acyl L-cysteine ester, wherein the acyl group is derived from fatty acids having from 1 to 9 carbon atoms, and the ester group is derived from fatty alcohols having from 1 to 22 carbon atoms.
Claim 11
Dependent Claim
21 words
The method of claim 8 wherein the acyl group is derived from fatty acids having from 1 to 4 carbon atoms.
Claim 12
Dependent Claim
21 words
The method of claim 8 where the ester group is derived from fatty alcohols having from 1 to 10 carbon atoms.
Claim 13
Dependent Claim
21 words
The method of claim 10 where the ester group is derived from fatty alcohols having from 1 to 4 carbon atoms.
Claim 14
Dependent Claim
24 words
The method of claim 11 wherein the derivative is selected from the group consisting of N-acetyl L-methionine methyl ester and N-acetyl methionine ethyl ester.
