Guar gum is extracted from Guar beans, commonly known as Cluster bean seeds. Guar seeds are collected from the pods, broken to separate the germ from endosperm, de-husked to remove the outer fibrous skin, polished and milled into coarse or fine-grained powder. Guar gums are used as thickening and stabilizing agent in various industrial applications including food industry. Processing techniques of Guar gum production varies for each product usage. Split endosperms of Guar seeds are pre-hydrated to obtain the required rate of hydration in final product. Pre-hydration helps in reducing the heat generation during grinding process. Soaked splits are then flaked, ground and sorted by the particle size. Quality of food-grade Guar gum is determined by the rate of hydration, size of granules, microbial content and viscosity development.
Guar gum powder is either fine or coarse in texture, free flowing, off white in colour, with thickening capacity eight folds higher than that of corn flour. The powder has first-rate solubility with cold and hot water, with exceptional water binding capacity. The viscosity rate of powder increases in water, while it decreases in other solvents, oils.
Some of the key applications of Guar gum are
- Natural Thickener
- Gelling agent
- Bonding agent
Guar gum powder is serving in wide range of industries such as food, pharmaceuticals, textiles, cosmetics, nutrition, paper, mining, and oil drilling.
In Food industry, Guar gum is used as thickening, emulsifying additive for stabilization, water retention, preservation in milk and dairy products, Ice creams, Jams, Bread, baked foods, Mayonnaise, ketchups etc. Guar gum reduces crystal formation, improves texture, maintains viscosity, controls moisture retention in food products
In Pharmaceutical industry, Guar gum is used as a binder and disintegrating agent in tablets, hydrocolloids in band-aids. As a source of natural fibre, it is widely used in dietary fibre capsules.
In Cosmetic industry, it is used as a thickening agent in skin care lotions, creams, personal care products.
Industrial grade Guar gum powder is a multipurpose product used in different applications. It is used as a flocculant in mining industry to separate liquid and solid, strengthening agent in paper industry providing hardness to paper, used as thickening agent in textile printing, fast hydrating guar gum is used as drilling aids in oil drilling industry.
