International ClassesC13J 001/06C13F 001/02 AbstractAn integrated process is disclosed which produces both crystalline fructose and a liquid-phase sweetener such as High Fructose Corn Syrup from a feed stream comprising dextrose. A portion of the dextrose in the feed stream is isomerized to fructose and the resulting dextrose/fructose stream is fractionated to produce a high fructose stream. A portion of the fructose in the high fructose stream is crystallized out and the mother liquor remaining after crystallization is blended with dextrose-containing streams to produce the liquid-phase sweetener.Other References
