Guar gum, also called guaran, is a galactomannan polysaccharide extracted from guar beans that has thickening and stabilizing properties useful in the 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. Chemically, guar gum is an exo-polysaccharide composed of the sugars galactose and mannose. Because it is gluten-free, it is used as an additive to replace wheat flour in baked goods. It has been shown to be beneficial to health. It has been shown to reduce serum cholesterol and lower blood glucose levels. Additional benefits have been seen in one’s efforts to lose weight where, when ingested, its water-absorbing properties cause it to swell in the stomach causing a ‘full’ sensation sooner. Guar gum is economical as well. Because it has almost eight times the water-thickening ability of other agents (e.g.cornstarch), only a small quantity is needed for producing sufficient viscosity. Because less is required, costs are reduced.
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.
