Abstract
Cellulose is converted to a form suitable for tablet making and other applications by subjecting it to hydrolysis using a cellulase enzyme for a time sufficient to yield a highly crystalline particulate hydrolysate which forms a hard, coherent mass when subjected to a predetermined compressive force.
