Abstract
Abstract An expanded edible protein product is made by extruding, preferably following heating and working of, a mix containing a proteinaceous material, a sulfur-containing organic compound, and water from a high pressure zone to a low pressure zone. The resultant product has an open, cellular structure and is an excellent meat-like substitute, convenience food and pet food ingredient, and snack item.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A method of preparing an expanded, edible protein product having an open, cellular structure comprising forming an admixture of proteinaceous material having a protein content of at least about 30% by weight, from about 0.05% to about 2.0% by weight of said proteinaceous material of a sulphur-containing organic compound selected from the group consisting of cysteine hydrochloride, D,L-methionine, sodium lignosulfonate, thiamine mononitrate, calcium thioglycollate and mixtures thereof, and water in an amount sufficient to result in a moisture content of 15 to about 50% by weight of said admixture; heating the mix to a temperature above about 220°F, mechanically working the heated mix at a pressure substantially above atmospheric pressure; and expanding the mix by suddenly releasing the pressure.
Claim 2
Independent Claim
119 words
A method of preparing an expanded, edible protein product having an open, cellular structure comprising forming an admixture of proteinaceous material having a protein content of at least about 30% by weight, from about 0.05% to about 2.0% by weight of said proteinaceous material of a sulphur-containing organic compound selected from the group consisting of cysteine hydrochloride, D,L-methionine, sodium lignosulfonate, thiamine mononitrate, calcium thioglycollate and mixtures thereof, and water in an amount sufficient to result in a moisture content of 15 to about 50% by weight of said admixture; heating the mix to a temperature above about 220°F, mechanically working the heated mix at a pressure substantially above atmospheric pressure; and expanding the mix by suddenly releasing the pressure.
Claim 3
Dependent Claim
71 words
The method of claim 1 wherein the mix is processed continuously through an extruder; the mix being subjected to mechanical working as it is moved from the inlet to the discharge of the extruder; the pressure in said extruder being substantially above atmospheric pressure; the pressure on the mix being released as it is forced through a die head at the discharge end of the extruder into an atmospheric pressure zone.
Claim 4
Dependent Claim
24 words
The method of claim 2 wherein said proteinaceous material and said sulfur-containing organic compound are dry blended before they are fed into the extruder.
Claim 5
Dependent Claim
54 words
The method of claim 1 wherein said expanded edible protein product is soft and moist, has a moisture content of at least 15% by weight, and is bacteriologically stable by virtue of the addition thereto of a material selected from the group consisting of potassium sorbate, salt, propylene glycol, glycerine, sugar and mixtures thereof.
Claim 6
Dependent Claim
24 words
The method of claim 4 wherein said edible protein product is expanded prior to mixing to introduce the soft moist characteristics with bacteriological stability.
Claim 7
Dependent Claim
86 words
An edible protein product comprising an extruded, expanded proteinaceous material having a protein content of at least about 30% by weight, said product having an open, cellular structure and containing added sulphur provided by from about 0.05% to about 2.0% by weight of said proteinaceous material of a sulphur-containing organic compound selected from the group consisting of cysteine hydrochloride, D,L-methionine, sodium lignosulfonate, thiamine mononitrate, calcium thioglycollate and mixtures thereof, said sulphur-containing organic compound having been admixed with said proteinaceous material prior to expanding said proteinaceous material.
Claim 8
Dependent Claim
86 words
An edible protein product comprising an extruded, expanded proteinaceous material having a protein content of at least about 30% by weight, said product having an open, cellular structure and containing added sulphur provided by from about 0.05% to about 2.0% by weight of said proteinaceous material of a sulphur-containing organic compound selected from the group consisting of cysteine hydrochloride, D,L-methionine, sodium lignosulfonate, thiamine mononitrate, calcium thioglycollate and mixtures thereof, said sulphur-containing organic compound having been admixed with said proteinaceous material prior to expanding said proteinaceous material.
Claim 9
Dependent Claim
12 words
The product of claim 6 wherein said proteinaceous material is soy meal.
Claim 10
Dependent Claim
12 words
The product of claim 6 wherein said proteinaceous material is wheat gluten.
Claim 11
Dependent Claim
15 words
The product of claim 6 wherein said proteinaceous material is a mixture of proteinaceous materials.
Claim 12
Dependent Claim
26 words
The product of claim 6 wherein said product is soft and moist, has a moisture content of at least 15% by weight, and is bacteriologically stable.
