Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 174 words
A process for the treatment of corn starch which comprises the steps of a) mixing<br><br> I) a starch component comprising granular corn starch,<br><br> ii) a surfactant component comprising at ^ least one surfactant containing a fatty acid moiety, and ill) water In the amount of k0%-<br><br> to 30% by weight of the total combined mixture, a.ny portion of which water may be present as the natural moisture content of said starch component, to form a uniform mixture;<br><br> 3<br><br> b) heating the mixture of Step a) at a temperature from 50°C to 85°C for at least<br><br> 1 hour in a closed container; and<br><br> -iS- : ■ lh i oi-<br><br> 28JANI987 7?<br><br> 209274<br><br> c) subjecting the product of Step b) to microwave radiation in an open container until the moisture content of the mixture is., reduced to below -15/5 by weight;<br><br> to produce a starch product having substantially complete hot-water dispersibility capable of forming a 5% dispersion when added to boiling water, said dispersion having a viscosity of at least 2000 centipoises when measured at 70°C.<br><br>
Claim 2
Dependent Claim 174 words
A process for the treatment of corn starch which comprises the steps of a) mixing<br><br> I) a starch component comprising granular corn starch,<br><br> ii) a surfactant component comprising at ^ least one surfactant containing a fatty acid moiety, and ill) water In the amount of k0%-<br><br> to 30% by weight of the total combined mixture, a.ny portion of which water may be present as the natural moisture content of said starch component, to form a uniform mixture;<br><br> 3<br><br> b) heating the mixture of Step a) at a temperature from 50°C to 85°C for at least<br><br> 1 hour in a closed container; and<br><br> -iS- : ■ lh i oi-<br><br> 28JANI987 7?<br><br> 209274<br><br> c) subjecting the product of Step b) to microwave radiation in an open container until the moisture content of the mixture is., reduced to below -15/5 by weight;<br><br> to produce a starch product having substantially complete hot-water dispersibility capable of forming a 5% dispersion when added to boiling water, said dispersion having a viscosity of at least 2000 centipoises when measured at 70°C.<br><br>
