Abstract
Abstract An edible suspension of a finely divided food material in a liquid suspending medium which swells cellulose, the suspension also containing microfibrillated cellulose in an amount sufficient to produce a stable, homogeneous suspension. The microfibrillated cellulose, a form of cellulose having a very large available surface area per unit of weight, acts to confer, among other benefits, greater stability on the suspension.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
31 words
An edible suspension comprising finely divided food material in a liquid suspending medium which swells cellulose, said suspension containing microfibrillated cellulose in an amount sufficient to produce a stable, homogeneous suspension.
Claim 2
Dependent Claim
31 words
An edible suspension comprising finely divided food material in a liquid suspending medium which swells cellulose, said suspension containing microfibrillated cellulose in an amount sufficient to produce a stable, homogeneous suspension.
Claim 3
Dependent Claim
14 words
The suspension of claim 1 in which the finely divided material is a solid.
Claim 4
Dependent Claim
9 words
The suspension of claim 1 containing a hydrophilic polymer.
Claim 5
Dependent Claim
28 words
The suspension of claim 3 in which the hydrophilic polymer is selected from the group consisting of cellulose esters and ethers, synthetic acid polymers, natural gums and starches.
Claim 6
Dependent Claim
48 words
The suspension of claim 1 in which the microfibrillated cellulose is present in an amount ranging from 0.25% to the major ingredient of the suspension, said proportions being based on the weight of cellulose solids present as microfibrillated cellulose as compared to the total weight of the suspension.
