Abstract
The present invention provides novel pyrodextrins which are substantially 100% soluble in water, and substantially hydratable in a solution which has low free water, at ambient temperature, have high viscosities relative to a canary dexrin and are solution stable. These dextrins are prepared by preferably acidifying the starch, and dextrinizing under substantially anhydrous conditions for a time and at a temperature sufficient to result in the desired end product.
Claims17
A dextrin characterized by:
- a. substantially 100% soluble in ambient water,
- b. substantially hydratable in an ambient solution which has low free water such that solution is clear;
- c. a borated viscosity greater than about 800 cps.
- d. solution stability.
The dextrin of claim 3, wherein the borated viscosity is greater than about 50,000 cps.
A process of manufacturing a dextrin comprising:
- a. dehydrating a starch to substantially anhydrous prior to reaching maximum dextrinizing temperature;
- and
- b. dextrinizing under substantially anhydrous conditions at the maximum dextrinizing temperature until the starch is substantially 100% soluble in ambient water, substantially hydratable in an ambient solution with low free water, has a borated viscosity greater than about 800 cps, and is solution stable.
