Abstract
Expanded bed isomerization of glucose syrup to a glucose-fructose mixture having a fructose proportion exceeding about 40% of the glucose-fructose content by passing 30-55% w/w of glucose syrup through a cell-mass glucose isomerase preparation in the form of a bed of uniform particles of controlled size in the range of 150-2000 micrometers at a superficial syrup velocity of 0.5-15 meters an hour. Velocity and particle size are inversely related to create bed expansion within the range of 5-100%. Bed life may be extended by substituting fresh catalyst for inactivated catalyst. The isomerase should have an activity exceeding about 100 IGIC u/gm. The isomerase should be weighted by incorporation therein of finely divided alumina particles.
