During last decade Guar has
immerged as an important industrial raw material and Produced by man for
thousands of years. India has been the single largest producer and
exporters of Guar gum accounting for more than 80 percent of the global
output and trade and that to involves a important share of A Part of North
Gujarat. (Western Part of India)
Guar has now assumed a larger
role among the domesticated plants due to its unique functional
properties.
The byproduct of Guar Gum
industry consisting of the outer seed coat and germ material is called
guar meal. The Guar meal after gum Extraction is a potential source of
protein and contains about 42% crude protein which is one and a half times
more than the level of protein in guar seed. The protein content in guar
meal is well comparable with that of oil cakes. It is used as a feed for
live stock including poultry. Toasting of Guar Meal improves its nutritive
value in chicks. Toasted guar Meal can be used in limited quantity i.e. Up
to 10% in Poultry diet. However it can replace groundnut cake by almost
100% in animals feeds.
Guar Gum (Galactomanan) is a high
molecular weight carbohydrate polymer made up of a large number of mannose
and galactose unit linked together. The crude Guar Gum is a grayish white
powder 90% of which dissolves in water. It is non ionic polysaccharide
based on the milled endosperm of the guar bean whose average composition
is :
The
most important property of the Guar is its ability of hydrate rapidly in
cold water to attain a very high viscosity at relatively low
concentrations. Its specific colloidal nature gives the solution an
excellent thickening power which is 6 to 10 times thicker than that
obtained from starch. It is stable over a wide range of PH and it also
improves the flowablility and pumpability of the fluid. It is a superior
friction loss reducing agent.
