Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
126 words
A method for preparing an expanded food product comprising grinding whole wheat having at least 11 percent protein, on a dry basis, to provide a ground whole wheat material, forming a dough from said ground wheat material, said dough having an edible acid present at a level of from about 0.01 to about 0.05 percent by weight equivalent lactic acid, working said dough while heating said dough, subjecting said heated dough to high temperature-short time heating conditions in a high pressure zone said acid and said working providing extensibility to said protein, extruding said heated dough from said high pressure zone to a low pressure zone, thereby effecting expansion of said dough, and drying said expanded dough to provide an expanded food product of desired moisture.
Claim 2
Independent Claim
126 words
A method for preparing an expanded food product comprising grinding whole wheat having at least 11 percent protein, on a dry basis, to provide a ground whole wheat material, forming a dough from said ground wheat material, said dough having an edible acid present at a level of from about 0.01 to about 0.05 percent by weight equivalent lactic acid, working said dough while heating said dough, subjecting said heated dough to high temperature-short time heating conditions in a high pressure zone said acid and said working providing extensibility to said protein, extruding said heated dough from said high pressure zone to a low pressure zone, thereby effecting expansion of said dough, and drying said expanded dough to provide an expanded food product of desired moisture.
Claim 3
Dependent Claim
29 words
A method in accordance with claim 1 wherein said edible acid is present at a level of from about 0.02 to about 0.04 percent by weight equivalent lactic acid.
Claim 4
Dependent Claim
14 words
A method in accordance with claim 1 wherein said double acid is lactic acid.
Claim 5
Dependent Claim
26 words
A method in accordance with claim 1 wherein said expanded food product has a density of from about 3.5 to about 4.75 pounds per cubic foot.
Claim 6
Dependent Claim
66 words
A method in accordance with claim 4, wherein said high temperature-short time heat treatment is effected by injecting steam into said extruder in a zone between a first die and a second die, said first die having a round aperture through which said dough enters said chamber and said second die having a slot off-set from said aperture whereby said expanded dough exits from said extruder.
Claim 7
Dependent Claim
40 words
A method in accordance with claim 5 wherein said first die is provided with two or more apertures and said second die is provided with two or more slots, each of said slots being off-set from each of said apertures.
Claim 8
Dependent Claim
25 words
A method in accordance with claim 5 wherein said first die is spaced from said second die by from about 0.05 to about 0.10 inch.
Claim 9
Dependent Claim
18 words
A method in accordance with claim 1 wherein said ground wheat has a maximum size of 0.040 inch.
Claim 10
Dependent Claim
96 words
A method in accordance with claim 1 wherein said ground wheat is present in said dough at a level of from about 75 to about 97 percent, dry basis, said extrusion aid is present in an dough at a level of from about 0.04 to about 3 percent, based on the weight of said wheat, said edible acid is present in said dough at a level of from about 0.02 to about 0.04 percent, based on the weight of said wheat, and said dough having a moisture content of from about 15 to about 30 percent.
Claim 11
Dependent Claim
25 words
A method in accordance with claim 1 wherein said dough is introduced into an extruder to effect said working and said heating of said dough.
Claim 12
Dependent Claim
93 words
A method in accordance with claim 10 wherein said dough is worked and heated in a first section of said extruder to a temperature of from about 100° F. to about 150° F. for a period of from about 5 to about 40 seconds and said dough is subjected to high temperature-short time heating conditions in a second section of said extruder for a period of less than about 1 second, the temperature of said dough being increased to from about 245° F. to about 370° F. during said high temperature-short time heating.
Claim 13
Dependent Claim
23 words
A method in accordance with claim 10 wherein said dough is extruded from said extruder through a die having at least one slot.
Claim 14
Dependent Claim
35 words
A method in accordance with claim 12 wherein said slot has a width of from about 0.020 inch to about 0.035 inch and has a length of from about 0.5 inches to about 3 inches.
Claim 15
Dependent Claim
15 words
A method in accordance with claim 11 wherein said edible acid is provided by yogurt.
Claim 16
Dependent Claim
15 words
A method in accordance with claim 1 wherein said edible acid is provided by whey.
Claim 17
Dependent Claim
15 words
A method in accordance with claim 1 wherein said dough further comprises a protein material.
Claim 18
Dependent Claim
29 words
A method in accordance with claim 16 wherein said protein material is present at a level of from about 5 to about 20 percent by weight of said wheat.
Claim 19
Dependent Claim
13 words
A method in accordance with claim 16 wherein said protein material is yeast.
Claim 20
Dependent Claim
17 words
A method in accordance with claim 1 including the step adding an extrusion aid to said dough.
Claim 21
Dependent Claim
13 words
The expanded food product made by the method set forth in claim 1.
Claim 22
Dependent Claim
13 words
The expanded food product made by the method set forth in claim 9.
