Guar Gum: Physical Characteristics

  • Guar Gum is a white to yellowish white powder and is nearly odorless. Fine finished Guar Gum Powder is available in different viscosities and granulometries depending on the desired viscosity development and applications.
  • Guar Gum is a natural high molecular weight hydrocolloidal polysaccharide composed of galactan and mannan units combined through glycosidic linkages, which may be described chemically as galactomannan.
  • Guar gum is a cold water soluble polysaccharide, consisting of mannose and galactose units. This ability to hydrate without heating makes it very useful in many industrial and food applications.
  • Dissolved in cold or hot water, guar gum forms a slime of high viscosity. Guar's viscosity is a function of temperature, time, and concentration.
  • Solutions with different gum concentrations can be used as emulsifiers and stabilizers because they prevent oil droplets from coalescing. Guar gum is also used as suspension stabilizer.

Guar Gum Powder Grades

The physical and performance characteristic of specific guar grades are determined by mechanical treatment before and after the endosperm is milled to its final, light tan flour form. Guar grades hydrate in both cold and hot water to yield viscous solutions.

Different guar gum powder grades are manufactured as per its industrial applications; for thickening, stabilizing, texturizing, enhancing suspension and flow control properties for industrial products, food products and processes.

For industrial use, addition of desirable qualities such as dust elimination for powdered products, the manufacture of stronger pellets, better flocculation or slip aids, for your processes or finished products.

There are two types of Guar Gum Powder

1) Food grade Guar Gum Powder: for used in industries like food, pharmaceutical, cosmetic etc

There are various of applications of food grade guar gum powder

Particle Size          Viscosity Range (Cps)

100 MESH                3000-6000
-100 80% MIN

200 MESH                2000-9000
-200 90% MIN.

2) Industrial grade Guar Gum Powder: For used in industries like paper,mining, explosive, Oil-drilling etc

There are various of applications of industrial grade guar gum powder

Particle Size          Viscosity Range (Cps)

The grade of Guar Gum Powder depends upon:

  • Active matter content
  • Granulation
  • Viscosity
  • pH
  • Degree of substitution

Guar Gum Powder as a thickening agent

Thickening agents, or thickeners, are substances which, when added to the mixture, increase its viscosity without substantially modifying its other properties, like taste. They provide body, increase stability, and improve suspending action. Thickening agents are often food additives.

Thickener is a food product used to provide a thicker texture to a liquid or food dish. Some thickeners are used for medical purposes to enable the swallowing of food to occur more easily, without choking. Thickeners are also used to improve the texture or flavor of the food dish.

The most common used of Guar gum is its use as thickening agent or thickener. The thickening agent provides body, increase stability, and improve suspending action. Thickening agents are most often as food additives. Thickeners are frequently based on polysaccharides (starches or vegetable gums) or proteins.

Guar Gum is a thickening agent derived from guar beans which is very useful in various baking applications. 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 normal flour would.

Guar gum is widely used in food industries as thickening agent.
