Guar gum, also called guaran, is a galactomannan polysaccharide extracted from guar beans that has thickening and stabilizing properties useful in food, feed, and industrial applications. The guar seeds are mechanically dehusked, hydrated, milled and screened according to application. It is typically produced as a free-flowing, off-white powder

It has wide applications in inudstry especially in food industry (juices, mayonnaise and ketchup), bakeries, cement industry, textile industry, paper industry and in petroleum drilling. It is used as thicekening, binding and stabilizing agent and as an emulsifier.

• In baked goods, it increases dough yield, gives greater resiliency, and improves texture and shelf life; in pastry fillings, it prevents “weeping” (syneresis) of the water in the filling, keeping the pastry crust crisp. It is primarily used in hypoallergenic recipes that use different types of whole-grain flours. Because the consistency of these flours allows the escape of gas released by leavening, guar gum is needed to improve the thickness of these flours, allowing them to rise as a normal flour would.
• In dairy products, it thickens milk, yogurt, kefir, and liquid cheese products, and helps maintain homogeneity and texture of ice creams and sherbets. It is used for similar purposes in plant milks.
• For meat, it functions as a binder.
• In condiments, it improves the stability and appearance of salad dressings, barbecue sauces, relishes, ketchups and others.
• In canned soup, it is used as a thickener and stabilizer.
• It is also used in dry soups, instant oatmeal, sweet desserts, canned fish in sauce, frozen food items, and animal feed

• Textile industry – sizing, finishing and printing
• Paper industry – improved sheet formation, folding and denser surface for printing
• Explosives industry – as waterproofing agent mixed with ammonium nitrate, nitroglycerin, etc.
• Pharmaceutical industry – as binder or as disintegrator in tablets; main ingredient in some bulk-forming laxatives
• Cosmetics and toiletries industries – thickener in toothpastes, conditioner in shampoos (usually in a chemically modified version)
• Hydraulic fracturing Shale oil and gas extraction industries consumes about 90% of guar gum produced from India and Pakistan.
