Starch intermediate product, a process for producing a starch intermediate product, and a process for further processing of a starch intermediate product

A process for producing homogeneous products from an activated starch or amylose intermediate product, comprising the steps of:

• (a) swelling and disintegrating starch or amylose with a dilute aqueous alkali hydroxide solution;
• (b) precipitating the disintegrated starch or amylose from the agueous solution by adding a precipitant which is miscible with water;
• (c) separating the precipitated disintegrated starch or amylose, comprising activated hydroxy groups, from the filtrate, producing an activated starch or amylose intermediate product adapted to produce a homogeneous product;
• and
• (d) reacting activated hydroxy groups of the activated starch or amylose intermediate product with an agent selected from the group consisting of ether, ester, urethane, carbamate, and acetal to produce a homogeneous product.
