Guar Gum Powder ::
Guar Gum is a white to yellowish white powder. It is
nearly odorless. Dissolved in hot or cold water guar gum forms a
paste of high viscosity. Guar's viscosity is a function of
temperature, time and concentration.
-
It is
soluble in hot and cold water but insoluble in most organic
solvents.
-
It is
non-ionic and maintains a constant high viscosity over a broad
range of pH.
-
The
viscosity of its solution increases gradually with increasing
concentration of guar gum in water.
-
Temperature, pH, presence of salts and other solids influence
the viscosity of guar gum solution.
-
guar
gum forms highly viscous colloidal dispersions when hydrated in
cold water. The time required for complete hydration in water
and to achieve maximum viscosity depend on various factors,
i.e., the pH, temperature, grade of powder used and equipment
etc.
-
guar
gum is compatible with a variety of inorganic and organic
substances including certain dyes and various constituents of
food.
-
guar
gum has excellent thickening, emulsifying, stabilizing and film
forming properties
-
At very
low concentration, guar gum has excellent settling
(flocculation) properties and it acts as a filter aid.
Guar gum powder has strong hydrogen bonding
properties.
