Introduction:
Dextrose Monohydrate is
moderate in sweetness. It is 65-70% as sweet as sucrose and
has a solution, which is much less viscous than Liquid
Glucose. DMH is freely soluble in water at room temperature
and also in boiling alcohol.
The perceived sweetness
can be increased to the level of sucrose in some
Dextrose/Sucrose blends. Dextrose has a greater depression of
freezing point than that of cane sugar, resulting in a
smoother and creamier texture of the final product like in
frozen food products. The bulk density of DMH is 0.65 to 0.70
kg/cc.
Chemically, DMH has
reducing properties due to open chain aldehyde form, which
exists in equilibrium. In acidic solution, DMH yields
condensation, products such as maltose and gentibiose and in
alkaline solution it isomerizes to fructose and its compounds.
When oxidized with dilute alkali, DMH gives gluconic acid and
with nitric acid it gives saccharide, tartaric and oxalic
acids. DMH on hydrogenation yields a mixture of glycols such
as sorbitol.
DMH
is a good source of commercial carbon dioxide as it is 100%
fermentable in nature. It is an important ingredient of
microbial feed for the synthesis of antibiotics.

Application:
Food
Grade
Dextrose Monohydrate is purified and crystallized D-glucose.
It contains one molecule of water of crystallization. It
exists in white, odourless, crystalline granules having a
bland and sweet taste.
Food
Application:
• Bakery Products:
DMH has several functional purposes in yeast-raised foods,
such as Bread and Buns. The primary purpose is to supply
fermentable carbohydrate, on which the yeast may grow and
provide CO2 for 'raising' the product. Its presence also
assists in browning of the crust to give a final product that
is pleasing in appearance and aroma.
• Biscuits:
DMH can partially replace sucrose in fondants and cream
fillings where fine crystals are required for a smooth
texture.
• Alcoholic Beverages:
DMH has high fermenting ability and can be added to low
calorie beer for complete fermentation of alcohol. No
carbohydrate residue remains to increase the calories in the
beverages.
• Canned Products:
DMH is used in canned vegetables and fruits in some instances
for controlling
sweetness and preserving properties.
• Confectionaries:
DMH is used extensively for sweetening and coating, chewing
gum and bubble gum.
DMH improves the color and gloss of the gum coatings and its
high heat of solution
gives a cool texture in all gum and candy coating
applications.
DMH contributes to the tenderness; whip ability, and sweetness
in marshmallow
and nougat applications.
• Meat Industry
The presence of sugar (particularly reducing sugar) in the
curing mixture has a direct
bearing on the quality of the color obtained at the end of
cure.
• Frozen Desserts
DMH can help control ice crystals and body of frozen dairy
products.
• Other Applications
Jams, Jellies, Preservatives, Peanut Butter, Seasoning,
Pickle, Vinegar Fermentation, etc.
Industrial
Applications:
• Adhesives
DMH provides flow control and helps prevent wrapping of the
pieces upon drying.
• Resin Formulation
DMH can serve as plasticiser in various resin formulations.
• Gluconic Acid
DMH can serve as feedstock for chemical or microbiological
oxidation to gluconic acid.
• Building Materials
DMH can be used in wallboard as a humectant to control water
release and to prevent brittle edges during drying, as setting
retardants in concrete.
• Other Applications
The Reducing Properties of dextrose are used in metal
treatment, recovery, dye
applications, leather manufacture in chrome tanning, etc.
DMH is used as carbohydrate sources in fermentations to
produce a variety of industrial, food and pharmaceutical
products.
