Abstract

Abstract There is disclosed compositions comprising primarily mixtures of edible cellulose fibers and/or colloidal cellulose microfibrils, incorporated with low-molecular animal and/or vegetable proteins, crosslinked with edible non-covalent and/or covalent crosslinking agents. The compositions possess a water-expandable property such as to grow in volume in an aqueous acidic medium and serve as a firm gelatinous binder for the edible components. The above mixture is compressed in dry powder forms into tablets and/or granular compositions capable of swelling at the acid pH of the stomach into a firm gelatinous physical mass or masses that effectively serve to provide a temporary reduction of the appetite by mechanical rather than systemic action.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 133 words
A method for the preparation of a low calorie edible product adapted to expand to a swollen gelatinous mass at least 3 times its original volume when ingested and comes into contact with the gastric juice of the stomach which comprises forming an aqueous solution of animal or vegetable protein, adding to the solution an edible crosslinking agent sufficient to cross-link said protein, aerating the solution subjected to cross-linking, cooling the aerated solution to form a gel, drying the gel to a moisture content of less than about 10%, comminuting the dried gel to form finely divided, particulate, aerated protein; dry blending the particulate, aerated protein with particulate edible cellulose, the particulate, aerated protein constituting from about 10 to 50%, by weight of the blend and compressing the blend into a shaped form.
Claim 2
Independent Claim 133 words
A method for the preparation of a low calorie edible product adapted to expand to a swollen gelatinous mass at least 3 times its original volume when ingested and comes into contact with the gastric juice of the stomach which comprises forming an aqueous solution of animal or vegetable protein, adding to the solution an edible crosslinking agent sufficient to cross-link said protein, aerating the solution subjected to cross-linking, cooling the aerated solution to form a gel, drying the gel to a moisture content of less than about 10%, comminuting the dried gel to form finely divided, particulate, aerated protein; dry blending the particulate, aerated protein with particulate edible cellulose, the particulate, aerated protein constituting from about 10 to 50%, by weight of the blend and compressing the blend into a shaped form.
Claim 3
Dependent Claim 48 words
The method as defined in claim 1 wherein the particulate edible cellulose constitutes 50%, by weight, of the blend and consists of 30 to 35%, by weight of the blend, of finely divided particulate, alpha cellulose and 20 to 15%, by weight of the blend, of microcrystalline cellulose.
Claim 4
Dependent Claim 26 words
The method as defined in claim 1 wherein the blend is compressed into a shaped form at a pressure of between about 1000 and 7500 psi.
Claim 5
Dependent Claim 76 words
As an article of manufacture, a low calorie edible compressed shaped form consisting essentially of from 10 to 50%, by weight, finely divided, particulate, aerated, cross-linked animal or vegetable protein containing less than 10% moisture and the balance particulate edible cellulose, the shaped form being further characterized in that when ingested and upon coming into contact with the gastric juice of the stomach expands into a swollen gelatinous mass at least 3 times its original volume.
Claim 6
Dependent Claim 76 words
As an article of manufacture, a low calorie edible compressed shaped form consisting essentially of from 10 to 50%, by weight, finely divided, particulate, aerated, cross-linked animal or vegetable protein containing less than 10% moisture and the balance particulate edible cellulose, the shaped form being further characterized in that when ingested and upon coming into contact with the gastric juice of the stomach expands into a swollen gelatinous mass at least 3 times its original volume.
Claim 7
Dependent Claim 16 words
An article of manufacture as defined in claim 4 wherein the protein is an animal protein.
Claim 8
Dependent Claim 14 words
An article of manufacture as defined in claim 4 wherein the protein is gelatin.
Claim 9
Dependent Claim 15 words
An article of manufacture as defined in claim 4 wherein the protein is soybean protein.
Claim 10
Dependent Claim 54 words
An article of manufacture as defined in claim 4 wherein the protein constitutes about 50%, by weight of the shaped form, and the particulate edible cellulose consists of 30 to 35%, by weight of the shaped form, of finely divided particulate alpha cellulose and the balance of the shaped form consists of microcrystalline cellulose.
Claim 11
Dependent Claim 55 words
An article of manufacture as defined in claim 4 wherein the protein is gelatin and constitutes 50%, by weight, of the shaped form and the particulate edible cellulose consists of 35%, by weight of the shaped form, of finely divided particulate alpha cellulose and of 15%, by weight of the shaped form, of microcrystalline cellulose.
