Glucose (dextrose), produced by enzymatic decomposition from starch, is very quickly absorbed. It is a very valuable substitute for ordinary sugar if you suffer from Fructose Malabsorption or Fructose Intolerance. It is available at chemist’s/drugstores and supermarkets. Every commercially available dextrose contains up to 10% crystal water. The contained water is bound in the crystal structure of the dextrose, but is freed, when the dextrose is dissolved, e.g. in a cake batter. This is the reason, that often people say, that dextrose makes doughs or other dishes more liquid. A good rule of thumb is that when using 1kg dextrose, expect this adds about 85ml of water. However, our Corn Sugar doesn't contain crystallised water.
