Gellan gum to improve physical stability of liquid nutritional products
First Claim
Patent Images
1. A method for the reduction of sedimentation in a nutritionally complete liquid formula, said method comprising the steps of:
- a) hydrating gellan gum in water;
b) combining said hydrated gellan gum with a slurry selected from the group consisting of a protein slurry, a carbohydrate slurry, a fat slurry and mixtures thereof to form a gellan gum slurry, and;
c) combining a sufficient quantity of said gellan gum slurry with one or more slurries and/or premixes to result in a nutritionally complete liquid formula;
i) having a caloric content of from about 500 calories to about 2000 calories per liter and containing suspended minerals, vitamins, proteins, carbohydrates and fats sufficient to allow said composition to be the sole source of nutrition for a human,ii) containing total solids in the range of from about 10% to about 35% by weight, and,iii) said gellan gum is present in said nutritionally complete liquid formula at a concentration of about 10 to about 500 parts per million, and wherein said nutritionally complete liquid formula has a yield stress of about 0.1 to about 1.0 dyne per square centimeter.

Abstract
Liquid, nutritionally complete formulas are disclosed with improved physical stability. The nutritionally complete formulas are pourable, yet are able to hold minerals, insoluble fiber and flavoring agents such as cocoa powder in suspension without the formation of a sediment that is not readily redispersible. The invention comprises the use of gellan gum at a concentration of between 10-500 parts per million. Although gellan gum alone is sufficient, the nutritionally complete formula may also comprise other stabilizers such as carrageenan and/or carboxymethylcellulose.
