Abstract:
A continuous process for providing substantially dry and uncoated segments consisting essentially of at least one amino acid as substantially the only active ingredient, said at least one amino acid being 35%-100% pure on a dry weight basis, said process comprising the steps carried out in the following order:(a) mixing a starting material consisting essentially at least one substantially pure amino acid with an aqueous solution to make an extrudable mixture which is sufficiently dense and cohesive to provide at least one noodle, said at least one amino acid being selected from a group consisting essentially of lysine, tryptophan and threonine; (b) extruding said extrudable mixture with a compressive force to provide at least one dense and cohesive noodle which can be segmented; (c) segmenting said at least said one noodle to provide said segments; (d) drying said segments of step (c) to make substantially dry segments; (e) milling said substantially dry segments of step (d) to make dense free-flowing non-dusting randomly shaped granules; and (f) sieving said granules of step (e) to select granules having a size range of about 177-1190 microns.
