Abstract
Abstract A food product containing microfibrillated cellulose is prepared by mixing together an edible liquid which swells cellulose, a food additive and fibrous cellulose to form a liquid suspension. The suspension is repeatedly passed through a small diameter orifice in which the mixture is subjected to a pressure drop of at least 3000 psig and a high velocity shearing action followed by a high velocity decelerating impact. The process converts the cellulose into microfibrillated cellulose and forms a stable homogeneous suspension of the microfibrillated cellulose, liquid and food additive.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
A process for the preparation of a food product comprising mixing together an edible liquid which swells cellulose, an additive which imparts a food flavor and fibrous cellulose to form a liquid suspension, said liquid suspension containing no more than 10% by weight of fibrous cellulose, repeatedly passing said liquid suspension through a high pressure homogenizer having a small diameter orifice in which the mixture is subjected to a pressure drop of at least 3000 pounds per square inch gauge and a high velocity shearing action followed by a high velocity decelerating impact against a solid surface, said process converting said cellulose into microfibrillated cellulose and forming a stable homogeneous suspension of said microfibrillated cellulose, liquid and food additive.
Claim 2
Dependent Claim
119 words
A process for the preparation of a food product comprising mixing together an edible liquid which swells cellulose, an additive which imparts a food flavor and fibrous cellulose to form a liquid suspension, said liquid suspension containing no more than 10% by weight of fibrous cellulose, repeatedly passing said liquid suspension through a high pressure homogenizer having a small diameter orifice in which the mixture is subjected to a pressure drop of at least 3000 pounds per square inch gauge and a high velocity shearing action followed by a high velocity decelerating impact against a solid surface, said process converting said cellulose into microfibrillated cellulose and forming a stable homogeneous suspension of said microfibrillated cellulose, liquid and food additive.
Claim 3
Dependent Claim
22 words
The process of claim 1 in which the additive is fruit juice concentrate and the food product is a filling or crush.
Claim 4
Dependent Claim
22 words
The process of claim 1 in which the additive is meat flavored bouillon and the food product is a soup or gravy.
Claim 5
Dependent Claim
25 words
The process of claim 1 in which the additive is a nonfat dry milk and a hydrophilic polymer and the food product is a pudding.
Claim 6
Dependent Claim
13 words
The process of claim 1 in which the food product is a dip.
Claim 7
Dependent Claim
22 words
The process of claim 1 in which the additive is soybean oil and a sweetener and the food product is a topping.
Claim 8
Dependent Claim
25 words
The process of claim 1 in which an hydrophilic polymer is added to the starting mixture before passing the suspension through the small diameter orifice.
Claim 9
Dependent Claim
32 words
The process of claim 7 in which the hydrophilic polymer is selected from the group consisting of a cellulose ester and ether, a synthetic acid polymer, a natural gum and a starch.
Claim 10
Dependent Claim
8 words
The product of the process of claim 1.
