A process for the production of the same is further disclosed wherein the glycitol is provided in the form of reduced millet jelly or reduced cyclodextrin millet jelly.Field of SearchAgitating to form larger particles (i.e., accretion or agglomeration)With subsequent cutting, grooving, breaking, or comminuting To form particulate product (e.g., flakes, etc.) Subsequent to extruding step By cutting at point of extrusion From strands By calendering Shaping by extrusion With processing before extrusion or inclusion of additive Utilizing added agent (e.g., flux, plasticizer, dispersing agent, etc.) Processing or treatment after extrusion Screw extruder or screw feeder device Introducing material under pressure into a closed mold cavity (e.g., injection molding, etc.) Ethylenically unsaturated polymer or polymer derived from ethylenically unsaturated monomer |
