Abstract
Abstract Clear stable gels are made from hydrogenated maltose containing starch hydrolysates having 25-94% maltitol, 2-30% sorbitol, and minor amounts of higher saccharides by the addition of amorphous silica gelling agents. These gels are useful in formulating cosmetics, pharmaceuticals, confections and food specialties. They are particularly useful in preparing clear gel toothpaste compositions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
81 words
A non-crystallizing edible gel useful in formulating cosmetics, pharmaceuticals, confections and food specialties consisting essentially of an aqueous maltitol containing syrup resulting from the hydrogenation of maltose rich syrups which comprise 36-49% by weight maltitol, 11-14% by weight sorbitol, minor amounts of higher saccarides and reducing sugars when said ingredients are calculated on a dry basis said syrup having a total solids content of 75-85% by weight when calculated on a wet basis and 5-10% by weight of a gelling agent.
Claim 2
Dependent Claim
