The gum extracted from the seeds of guar plant is chosen for multiple industrial applications as it contains wide range of properties which remains supportive in many industrial applications. The endosperm gum powder is purified under different methods before it is accepted for industrial usage. It is decided upon the reactivity shown by its endosperm when blended with different substances and components at the time of extraction and purification. However, when it comes to commercial use, the seeds are sent for varieties of purification methods in which the natural properties takes a different turn through showing less ration of protein and polysaccharides contaminations. In some cases the chemical properties changes when processed under cross linking methods. The by-product obtained after every form of cross linking is chosen for industrial applications based on molecular weight and properties
