| Guar
Gum Powder (Food Grade)
|
 |
The
primary use of Guar gum is as a food additive. Food additives play a vital
role in today's bountiful and nutritious food supply. Legally it refers to
any substance the intended use which results or may be reasonably be
expected to result-directly or indirectly-in its becoming a component or
otherwise affecting the characteristics of any food. This definition
includes any substance used in the production, processing, treatment,
packaging, transportation or storage of food. Additives have been used for
many years to preserve, flavor, blend, and thicken foods, and have
played an important role in reducing serious nutritional deficiencies among people.

Guar
gum as a water-soluble polymer has found a broad range of applications in
the production of petroleum. It serves one or more functions, such as
Water-loss
control,
Viscosity
control,
Flocculation,
Suspension,
Turbulent
friction
Reduction
or
Mobility
control

The
use of guar gum as a suspending agent for sand in drilling mud and in
fracturing fluids led to the discovery that guar solutions have lower
friction than water. Guar has become a widely used material for both
industrial and experimental friction reduction because of the robust
characteristics of its molecule, which tend to prevent degradation due to
high shear forces. When using the optimum concentration, the horsepower
required for the fracturing operation is reduced by a factor of over five.

| Mining |
 |
Guar
gum is used in froth flotation of postash as an auxiliary reagent,
depressing gangue minerals, which might be clay, talc, or shale. Guar gum is
also used as a flocculants (settling agent) to concentrate ores or tailings
in the mining industry. In practice, slimes and tailings from ore
beneficiation processes are concentrated so that the water can be reused and
the solids easily processed.

Pet Food |

Used
in preparation of pet foods. There are number of qualities of guar powder
based on mesh sizes, viscosities, etc. Some broad specifications of most
common varieties are given below. These are only broad specifications and
can vary and can be varied. Some tailor made qualities can also be
manufactured according to buyers’ specific requirements.

|
| Applications
for guar gum in food differ from country to country.
|
In
soft cheeses, the use of guar increases the yield of curd solids and gives
curds of a soft, compact, tender texture with a separated whey that is very
limpid. Guar gum has important uses in frozen foods because it provides
hydration and water-binding properties. In cake mixes guar gum allows
single-step mixing procedures, reduced batter mixing time, less crumbling
tendency in finished cake, easy application of frostings, and greater
moisture retention and pronged shelf life. In baked goods, adding guar gum
solutions to dough while kneading gives increased yields as well as giving
the dough a greater resiliency and a drier, less flabby appearance. It is
also used as a binder and lubricant in the manufacture of sausage products
and related stuffed meat products. In canned meat products and pet foods,
guar gum allows reducing of the bumping tendency during the cooking of the
meat, increase in the ease of pumping of the cooked product between the
kettle and filling vat, and reduction of splashing and spilling of contents
while filling. In dressings and sauces guar gum is used as a thickener
because of its ability to disperse in cold water, its compatibility with
highly acidic emulsions, and its ability to add viscosity. Guar gum is also
used in the beverage industry, specially in fruit juices as a stabilizer.
Examination
of the list of ingredients of most formulated foods will reveal guar gum as
an ingredient. For the food industry, our products and may be used, depending on the viscosifying, emulsifying,
water binding, or stabilizing strength required. |

| Cosmetics &
Pharmaceuticals |
 |
Guar
gum is used to thicken various cosmetics and pharmaceuticals. It is also
used to bind and to disintegrate compressed tablets and pellets. It is also
used as a mild laxative. |
|
 |
|
| |
|
| Explosives |
 |
Guar
gum is used in the explosives industry as a waterproofing agent. Its ability
to hydrate in saturated solutions of ammonium nitrate causes it to be widely
used in this industry. For this purpose DFS-33 is the most commonly used
guar gum products. |
| |
|
 |
Guar
gum forms viscous colloidal dispersions when hydrated in cold water. Its
viscosity is measured using a rotations, shear-type viscometer such as the
Brookfield Viscometer. The solution is prepared by adding dry gum to an
agitated tank of water. The guar gum is permitted to thicken and hydrate for
a certain time, and the viscosity is measured. |
