Abstract
Abstract A modified pregelatinized starch which is readily dispersible in water comprising a pregelatinized starch coated with from 0.05 to 20% by weight of a food grade emulsifier. A process for producing a coated pregelatinized starch comprising blending a pregelatinized starch with a mixture of a non-toxic solvent and a food grade emulsifier followed by removing the solvent.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
123 words
A modified pregelatinized starch which is dispersible in liquids without agglomeration consisting essentially of from about 99.0 to 99.95% by weight of a pregelatinized starch selected from the group consisting of tapioca starch, corn starch, wheat starch, potato starch, rye starch and mixtures thereof, and from about 0.05 to 1.0% by weight of a food grade emulsifier consisting of a mixture of distilled propylene glycol monoesters, distilled monoglycerides, and sodium stearoyl lactylate wherein the emulsifier substantially coats and substantially encapsulates the starch to prevent agglomeration when the substantially encapsulated starch is added to liquids and to form a thin coating such that upon minimal agitation the starch is dispersed throughout a liquid medium to which it is added and thickens said liquid medium.
Claim 2
Dependent Claim
123 words
A modified pregelatinized starch which is dispersible in liquids without agglomeration consisting essentially of from about 99.0 to 99.95% by weight of a pregelatinized starch selected from the group consisting of tapioca starch, corn starch, wheat starch, potato starch, rye starch and mixtures thereof, and from about 0.05 to 1.0% by weight of a food grade emulsifier consisting of a mixture of distilled propylene glycol monoesters, distilled monoglycerides, and sodium stearoyl lactylate wherein the emulsifier substantially coats and substantially encapsulates the starch to prevent agglomeration when the substantially encapsulated starch is added to liquids and to form a thin coating such that upon minimal agitation the starch is dispersed throughout a liquid medium to which it is added and thickens said liquid medium.
Claim 3
Dependent Claim
12 words
The composition of claim 1 wherein the starch is a tapioca starch.
