PROCESS FOR PREPARING CYCLOOCTAAMYLOSE ABSTRACT OF THE DISCLOSURE A process for preparing cyclooctaamylose by enzymatic cleavage of an aqueous preparation of starch in the presence of a complexing agent is disclosed. As a selective com- plexing agent for cyclooctaamylose, a compound of the formula I is employed. (I) Image in which A, B, D and E, independently of one another, represent Image , and (R = hydrogen, alkyl, hydroxyl, alkoxy or carboxyl radical), and m, n, o and p are within the limits 0 to 20, with the proviso that the number of atoms forming the ring is within the limits from 13 to 24.
