Guar gums find wide uses in many of the most common aspects of our lives. Many foods utilize guar as a special additive to improve handling, smoothness, shelf life and other characteristics. Pet food also is improved by the use of guar gum in its formulation.
Creases dough yield, gives greater resiliency, and improves texture and shelf life.
Thickens ice creams, sherbets, cheese, liquid milk products, etc.
Functions as lubricant and binder.
Dressing and sauces:-
Improves the stability and appearance of salad
Barbecue sauces, relishes, ketchups and others (especially highly acidic emulsions).
Pharmaceutical and Cosmetics.-
Tablets, Capsules Syrups.
Dry soups, sweet desserts, and canned fish in sauce, frozen food items and animal feed. Guar gum can be used as a thickener for various cosmetics and pharmaceuticals. In compressed tablets guar gum can be used as a binder and disintegrator.
30 years ago, guar gum was mainly used as a disintegrate and binder in tablet. Today, guar gum is also used as a controlled-release agent for drug. Guar gum, drug and other ingredients are mixed and compressed into tablets. During dissolution studies, guar gum hydrates and forms a thick gel layer on the tablet surface. Consequently, drug releases out from the guar gum tablet in a sustained manner, achieving the desired kinetic effect. It also has been observed that bacterial flora in the large intestine degrade guar gum rapidly. Consequently, scientists developed successful delivery systems using guar gum to target drugs to ileum and large intestine.
Some people use guar gum to decrease appetite by providing a “feeling of fullness.” However, because of its swelling properties, guar gum may cause obstruction of the esophagus. Guar gum can swell as much as 20 fold. As discussed before, guar gum may retard chemical absorption. The chemicals also include glucose. Consequently, it may cause significant fluctuations in blood sugar levels. People with diabetes should not use these preparations. After fermentation of guar gum in the large intestine, the products including carbon dioxide, fatty acid and hydrogen will lower the pH of the medium. Researchers observed that ingestion of guar gum decreased the cholesterol and triglyceride levels but guar gum or other water-soluble, fermentable fibers increased the odd for colorectal cancer in a study of rats. One group explained that the soluble fiber did not raise distal butyrate concentration high enough to protect the colon from cancer. Butyrate demonstrated to slow the growth of cancer cells cultured in vitro. While, one group found that dietary fiber supplementation with 10% pectin or with 10% guar gum (fed during the promotional stage of carcinogen sis) suppressed colon cancer incidence to a significant extent in study of rats. Other found that guar gum was not carcinogenic. The inconsistent research findings on guar gum’s carcinogenic effect demonstrate the importance of experimental design.
Technical And Industrial Uses
Interest for Guar Gum is fairly recent: its initial development was due to a lack of Locust Bean Gum in the 1940s. Its large scale industrial production dates from the 1950s. Guar Gum is used as a thickener and emulsifier in commercial food processing. It is also used in paper manufacturing, textiles, printing, cosmetics and pharmaceuticals. Guar is an all-natural ingredient, unlike other common thickeners such as modified food starch and cellulose gum (CMC), and has been shown to provide important health benefits.
ies have shown that the consumption of Guar Gum lowers serum LDL cholesterol and triglyceride and increases glucose tolerance. It helps regulate the rate of absorption of nutrients, including sugar, spreading it over a longer period of time. The result is a slower rise in blood sugar levels, and a less rapid subsequent drop. In one recent study, rats fed Guar Gum as a part of their diets showed a 25% decrease in plasma cholesterol. Guar is also high in soluble dietary fiber.
Guar gum is used in the explosive industry because of their ability to efficiently thicken the nitrate salt solution which is basic component of slurry explosive formulations. The gums are readily cross-linked to from stable water-resistant gels.
Guar gum is used as a wet-end additive. It gives denser surface to the paper used for printing. It is also useful in foresheet formation, Mullen bursting strength, fold strength, tensile strength, measure of the force required, to pull a fiber from the surface of sheet, machine speed that all parameters are increased and porosity of the paper is decrees.
Guar gum is used in mining potash, gold, copper and platinum group metals (PGM) as a flocculent and as a depressant. Reliance Industries manufacturers a range of modified guar gum products tailor-made for the mining industry
Oil , Water ,Gas and Well Drilling
Guar gum and guar gum derivates are used in the fracturing of oil, gas and water wells. The guar gum is used to carry a river of sand and pumped into the ground at high pressure. This fractures the ground and then fills the fractures with sand, thereby making the ground more permeable and thereby increasing the recovery of oil, gas, or water in the existing well.
We manufacture a special grade of guar gum with ultra high viscosity and low insoluble (UHV-66) for this application. As guar is a natural product and degrades within a few days, unlike other polymers there is no damage to the environment by the use of guar in fracturing treatment.
Guar gums used as a binder for fragmented tobacco fines to produce reconstituted tobacco sheets. These flexible sheets with tensile strength and thickness of leaf tobacco are blended with leaf tobacco and retain the taste, flavor, and aroma of an all-leaf product. Sheets are formed by passing a moist mixture of guar, humectants, and tobacco fines between closely spaced steel rollers revolving at different peripheral speeds.
Used in: Ointments, Lotions, Hair Shampoos, Hair Conditioners etc.
Functions: Used as thickening agent, lubricating agent, suspending agent, detergent compatible thickener, protective colloid, film forming agent.
Used in: Tooth paste, Shaving cream etc.
Function: Due to high viscosity, it imparts slip for extruding the paste from the tube without any excessive pressure.
Guar gum and guar gum derivates are used in to major textile applications: as a printing thickener and as a binder in the sizing of yarns, particularly for denim sizing. In the textile printing industry, guar gum is used as a printing thickener to keep the dyestuff from spreading on the fabric (add photo of rotary printing machine).
In denim sizing, guar gum is used to bind the starch and stabilize the viscosity in the sizing agent. In this application, it has replaced acrylic polymers which are banned in many countries for use in textile products as they are considered carcinogens. The guar gum is used on a 2% basis by weight of starch (add photo of sizing Machine).
