Claim Text:
1. A method of making granular absorbent comprising gelatinizing an admixture comprised of starch in an extruder under sufficient pressure and temperature forming a clumping agent comprised of a carbohydrate polymer binder from at least some of the starch of the admixture during extrusion from the extruder producing a plurality of extruded liquid absorbing pellets having a bulk density no greater than 0.7 grams per cubic centimeter and comprised of a liquid soluble carbohydrate polymer binder clumping agent comprised of dextrin; and wherein the admixture has a moisture content low enough and the extruder operates at an extrusion pressure and temperature high enough to dextrinize starch in the admixture during at least one of gelatinization and extrusion by the extruder forming dextrin in each liquid absorbing pellet.
