About Guar Gum
Guar Gum is derived from the endosperm of the Guar plant. It is found in the seeds of Cyamopsis tetragonolobus and psoralioides, which are the annual leguminous plants. Guar gum is a high molecular weight carbohydrate extracted from a legume (a plant of pea family) crop that grows best in sandy soils. The guar plant grows well in climate with moderate, flashing rainfall and lot of sunshine.
Most important application of guar gum is in the form of a thickening agent. It is an edible carbohydrate polymer that is widely employed as a reagent for applications like adsorption and hydrogen bonding with mineral and cellulosic surfaces. Guar gum powder is non-ionic, free flowing, low pale white colored and coarse to fine grounded powder.
Guar gum has immense thickening power which almost eight times that of the corn starch. For this reason guar gum is used as a thickener and emulsifier in number of commercial food processing applications. It is used in dressings, milk products, sauces, and baking mixes and also an important product for use in various commercial and industrial applications including paper manufacturing, textiles, printing, cosmetics and pharmaceutical processes.
Guar Extracts
Guar extracts are the Guar Split/Gum 28% (+/- 1% variance) extracts from the guar seed. The guar extracts include Churi and Korma 67% whose ratio again is dependent upon the quality of the seed.
 |
Guar Gum Split/Gum extracted from the processing of guar gum is further refined to guar powder. |
 |
Churi and Korma are used for cattle feed |

Guar Gum Powder Properties
The guar gum when dissolves in water gives galactose, hexose sugar and mannose. The hexose sugars are soluble both in cold as well as hot water but cannot dissolve in most of the organic solvents. Guar gum’s viscosity increases in water. Therefore even smaller quantity of guar gum when used with water can be effective in producing high viscosities. However this viscosity of guar gum decreases with acids. The strong acids which can cause hydrolysis and alkalies in strong concentration tend to reduce the viscosity of guar gum. Adding borax solution will form a gelatinous mass. Guar gum can be used with starch, agar and alginate. Agro Gums offers high viscosity guar gum in 3500 CPS to 8000 CPS range.
 |
Guar gum has excellent solubility with water. It can dissolve in both hot as well as cold water. |
 |
Guar gum has film forming properties. |
 |
Guar gum shows stability in solutions across a wide range of pH values from 5-7 |
 |
Excellent thickening properties make it an efficient thickening agent. |
 |
Can give higher viscosity even in small quantity. |
 |
Shows resistance to oils, solvents and various greases. |
 |
Excellent water binding capacity. |
 |
Efficient functionality even at low temperatures. |
 |
Compatible with various hydrocolloids used in food |
| |
formulations. |
 |
Guar gum can be used to make derivatives for specific applications because it is a versatile product with number of free hydroxy groups. |
