Abstract:
A process for preparing a crystalline .alpha.-anhydrous dextrose wherein:a) a starch hydrolysate is prepared;b) said starch hydrolysate is nanofiltered over membranes in such a way as to obtain a nanofiltration permeate constituting a syrup with a high glucose content and a nanofiltration retentate;c) said syrup with a high glucose content is concentrated to a dry matter content of at least 70 wt. % of glucose, at a temperature in the range 50.degree. C. to 110.degree. C.;d) said concentrated syrup is crystallised by evaporation and agitation in such a manner as to obtain a crystalline mass containing at least 30 wt. % of the crystals;e) the crystals of .alpha. anhydrous dextrose thus obtained are separated, recovered and dried.
