METHOD OF EXTRUDING STARCH UNDER LOW MOISTURE CONDITIONS USING FEED STARCH HAVING COARSE PARTICLE SIZE

摘要

A method of extruding starch at a low total moisture content wherein the inlet feed comprises starch having a selected coarse particle size distribution, and more particularly, in a method of extruding starch having a total moisture content of 25% or less by weight based on the weight of the starch, to form an expanded product, the improvement comprising feeding starch to the extruder which has a particle size distribution such that 30% or more by weight of the starch has a particle size of at least 180 microns.
