Dextrose monohydrate

Anhydrous a-dextrose is manufactured by dissolving dextrose monohydrate in water and crysta11i2ing at 60—65°C in a vacuum pan. Evaporative crysta11i2ation is necessary to avoid color formation at high temperatures and hydrate formation at low temperatures. The product is separated by centrifugation, washed, dried to a moisture level of ca 0.1%, and marketed as a very pure grade of sugar for special appHcations.

The primary energy source in PN solutions is carbohydrate, usually as dextrose monohydrate. Available concentrations range from 5% to 70%. When oxidized, 1 g of hydrated dextrose provides 3.4 kcal. 

The dextrose monohydrate obtained today by the foregoing method is a high grade product practically pure chemically. Where higher purity is occasionally desired, this product is recrystallized by essentially the same methods as described earlier.18 The absence of appreciable amounts of impurities renders crystallization somewhat easier. Nevertheless, the tendency for uncontrolled spontaneous crystallization is still encountered so that care is necessary in cooling the mass at the...

Dextrose monohydrate was brought in a fluid bed dryer (Retsch Type TGI) wherein the ratio of air (in kg) to product (in kg) is 0.77. The product which contained about 9% of moisture was dried to obtain dehydrated dextrose monohydrate which contained less than 0.5% water. The total driving time was about 25 to 70 minutes at a temperature of the incoming air of between 90°C and 120°C. 

Dextrose monohydrate was brought in a horizontal-placed turbo-dryer (VOMM, Mailand, Italy). The dehydration occurred at a temperature of between 90° to 150°C in a stream of air of 5 Normalised m3/kg (i.e volume of gas at 0°C and 1 mbar) dextrose and a rotation speed of 1200 min-1. 

Dextrose monohydrate is purified, crystalline D-glucose containing one molecule of water of crystallization per molecule of D-glucose. 

Either anhydrous dextrose or dextrose monohydrate can be obtained by crystallization. Monohydrate crystallizers are large horizontal, cylindrical batch tanks or... 

Dextrose monohydrate is sometimes used as an alternative to sucrose in chewing gum, and in some countries this substitution is economically advantageous. The endothermic heat of solution of dextrose gives a cooling sensation in the mouth, a property that goes well with mint flavours but not with others. 

Dextrose monohydrate (1.71 mol glucose) was dissolved in 7.0 liters water and introduced into a Biolafitte glass fermenter tank having a working capacity of 15 liters. The solution was aerated with an air flow rate of 20 liters/minute while stirring 650 rev/minute at 40°C.
