About Guar Gum
India is native of guar or cluster bean where it is used as a vegetable. From hundreds of years Guar has been used as vegetable in India and Pakistan.
It is also used as cattle food, and as a green manure crop in agriculture. Guar gum comes from the endosperm of the seed of the legume plant Cyamopsis tetragonoloba; an annual plant, grown in dry regions of India as a food crop for animals.
In the early 1900s it was introduced to United States by India. In U.S., most of crop is grown for a lower grade of guar gum which is extensively used in the production of many industries.
There are various grades of Guar gums pure or derivative. Guar gum is a white to creamy coloured, free flowing powder and free from extraneous matter. Its ability to suspend solids, bind water by hydrogen bonding, control the viscosity of aqueous solutions, form strong tough films have accounted for its rapid growth and use in various industries. For example guar gum is used in paper, textile, oil drilling, mining, explosives, ore flotation and other various industrial applications.
Guar Gum Chemical structure
Guar gum is a polysaccharide, a long chain made of sugars galactose and mannose. Some other familiar polysacharides are starch and cellulose, which are made of long chains of the sugar glucose.
Guar gum is a galactomannana similar to locust bean gum consisting of a (14)-linked β-D-mannopyranose backbone with branchpoints from their 6-positions linked to α-D-galactose (i.e. 16-linked-α-D-galactopyranose). There are between 1.5 – 2 mannose residues for every galactose residue.
Guar Gum Manufacturing Process
In India, Guar gum is normally undertaken by using process of roasting, differential attrition, sieving & polishing in the commercial production.
The seeds of Guar are split and by sieving the endosperm & germ is separated from the endosperm. Through heating, grinding & polishing process the husk is separated from the endosperm halves and the refined Guar Gum split are obtained. Through grinding process the refined Guar split are then treated and converted into powder. Depending upon the requirement of end product various processing techniques are used.
Guar Gum Properties
The main properties of Guar Gum are as follows. Due to its various properties day by day new industrial application of Guar gum increases for commercial uses. A guar gum manufacturer provides 8000 cps guar gum and essentially guar gum from India.
Guar gum properties are easy solubility in both hot and cold water, water binding due to Hydrogen Bonding, fine film forming property, resistance to oils, greases & solvents, Best thickening action, Physiologically Inert nature, Non-ionic, Anionic or Cationic character.
