INTRODUCTION
Guar Gum is a natural water soluble nonionic
polysaccharide isolated from the seeds of
Cyamopsis tetragonolobus (Family
leguminous)1 (Figure.1). This plant is cultivated
for centuries in semiarid and subtropical areas
of Pakistan and India, and in some areas of
North Africa and South America. Guar was
introduced into the United States from India in
1903.2 Extraction technology of guar gum was
commercialized in USA in 1953 by General
Mills inc and Stein, Hall & Co. Originally Guar
gum introduced as a substitute of loctus bean
gum during world war (1940) due to the shortage of loctus bean gum for paper industry.
Now a day’s guar becomes top ranking
industrial gums due to its fascinating
properties3. Guar has known as “Black Gold”4-6
because demand supply has turned it into cash
crop and precious commodity. The world
consumption of guar gum reached at 150,000
tons per annum which got a further boost by
introduction of different modified forms. About
95 percent of the global market of its guar
products is covered by India and Pakistan. US
consumption of guar seed and derivatives is
estimated to be 40,000 tons per annum.
