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.
