Project Report on Hydroxy Propyl Guar (Hpg) And Carboxy Methyl Hydroxy Propyl Guar [EIRI-1526]

The guar bean tetragonolobus), an annual legume, is the source of guar gum. It grows best under conditions with frequent rainfall, but tolerates arid conditions well. India grows 80% of world production of Guar gum but due to strong demand, it is being introduced into new areas. It is mainly grown in areas of India (Rajasthan, Haryana, Gujarat and Punjab) Pakistan, Sudan, and USA. India produces 6.0 7.5 lakh tons of guar annually. In India Rajasthan and Haryana states contribute 85% of the total production. In Rajasthan, the district Jaisalmer, Barmer, Nagaur, Hanumangarh Jhunjhunu and Sikar. The districts in Haryana indulged in the production of guar are Bhiwani, Sirsa, and Rewari and the districts in Gujarat are Kutch, Banaskantha, Ahmedabad. Jodhpur city in Rajasthan is one of the India. Guar also known as cluster bean (leguminous crop. Guar is being grown for seed, is an annual plant, about 4 feet high, vertically Each pod is about 5-8 cm long and has seeds. The pods are used as a green vegetable or as a cattle feed besides extraction of guar gum. Guar seed consists of major three portions viz, the seed coat, the endosperm and the innermost proteinacious portion, the germ. The endosperm is mechanically separated from seeds which yields 35-40% of gum (galactomannan). The left out portion. i.e. the outer seed coat and the germ together constitute guar meal. The chemical structure of guar gum consists of D-mannose monomer units linked to each other by -(14) linkage, in order to form the main chain with D-galactose branches joined by -(16) bonds. On the average, the galactose branches occur on every other mannose unit.7 The exact ratio of galactose to mannose varies with the growing season. Guar gum is highly dispersible into cold and hot water and brines of various types and salinity.
