A solid fructose product comprising less than about 2 weight percent water and greater than about 60 weight percent crystalline fructose is prepared by combining an aqueous fructose syrup and a solid crystallization initiator and then contacting with air for about 12 to 48 hours. The fructose syrup comprises about 60 to 93 weight percent saccharide with about 85 to 100 weight percent of the saccharide being fructose. The air has an initial temperature of about 50.degree. to 80.degree. C. and a final relative humidity of less than about 20 percent.

Semi-crystalline fructose

Non-compacting, anhydrous dextrose conversion syrup product in particle form prepared by shearing and cooling a molten dextrose conversion syrup (preferably at 90-92% dry solids) to a temperature less than 200.degree. F., depositing and solidifying the fluid mass upon a supporting member to an anhydrous dextrose product, granulating the solidified product and drying the particles to less than 2% moisture. The anhydrous dextrose particles have unique properties and, if desired, may be used as a sugar or dextrose monohydrate replacement.

Solid anhydrous dextrose

Mother liquors obtained from a dextrose crystallization process may be upgraded for re-cycling to dextrose crystallizers by transferring the mother liquor through a bed of an adsorption agent which preferentially adsorbs either dextrose or oligosaccharides. A dextrose-rich portion of the mother liquor is then recovered from either the dextrose-rich fraction which passes through the bed or has been preferentially adsorbed and eluted from the bed with a solvent.
