Abstract
Abstract A fried tofu product, such as "aburage", "ganmodoki", "aburage casing" and "jointless aburage casing", is prepared without coagulants normally used in conventional processes for making tofu by forming a kneaded soy proteinaceous material or soy protein dough from a heat coagulable soy protein, shaping the protein dough into a desired shape (e.g., thin sheet, rounded disc, or tubular) and deep frying the shaped material in two successive stages. Egg components and/or edible oils or fats can be incorporated into the protein dough to improve the texture, taste and/or food value of the fried product.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim

A method for making a fried tofu product comprising kneading a mixture containing a heat coagulable soy protein and sufficient water to form a plastic-like, moldable soy protein dough, shaping said soy protein dough into the desired shape; and deep frying said shaped soy protein dough.
Claim 2
Independent Claim
46 words
A method for making a fried tofu product comprising kneading a mixture containing a heat coagulable soy protein and sufficient water to form a plastic-like, moldable soy protein dough, shaping said soy protein dough into the desired shape; and deep frying said shaped soy protein dough.
Claim 3
Dependent Claim
59 words
A method according to claim 1 wherein said deep frying step includes successive first and second stages with the temperature of the frying oil for the first stage being within the range of about 100° to 135° C and the temperature of the frying fat for the second stage being within the range of about 135° to 200° C.
Claim 4
Dependent Claim
43 words
A method according to claim 2 wherein said mixture contains about 15 to 45 parts by weight of said heat coagulable soy protein and 0 to 100 parts by weight of an edible oil or fat per 100 parts by weight of water.
Claim 5
Dependent Claim
44 words
A method according to claim 3 wherein said mixture contains about 20 to 40 parts by weight of said heat coagulable soy protein and about 11 to 60 parts by weight of an edible oil or fat per 100 parts by weight of water.
Claim 6
Dependent Claim
9 words
A product produced by the method of claim 4.
Claim 7
Dependent Claim
51 words
A method according to claim 3 wherein said mixture further includes an egg ingredient selected from the group consisting of egg white, egg yolk, whole egg or mixtures thereof, the amount of said egg ingredient, as egg protein, being about 1 to 10 parts by weight per 100 parts of water.
Claim 8
Dependent Claim
33 words
A method according to claim 6 wherein said fried tofu product is a tubular aburage casing which is produced by extruding said soy protein dough into a tubular extrudate during said shaping step.
Claim 9
Dependent Claim
9 words
A product produced by the method of claim 7.
Claim 10
Dependent Claim
9 words
A product produced by the method of claim 6.
Claim 11
Dependent Claim
