  • Patent number: 5514790
    Abstract: A process for producing a starch intermediate product in which the reactive hydroxy groups are activated by swelling and disintegrating starch with dilute aqueous-alkali lye, precipitating the disintegrated starch from an aqueous-alkali solution by adding a precipitant which is miscible with water, separating the precipitated disintegrated starch, which exists in a highly activated form, from the filtrate producing a starch intermediate product, and drying the starch intermediate product. A starch intermediate product produced by this process results in a starch which exists in a highly activated form but which is stable in storage.
