STRATEGIC REPORT ON GUAR SEED AND GUM

The purpose of this report is to provide an inside look and overview about the production, processing and consumption of Guar in various industries around the globe. Guar or cluster bean is believed to have originated in Africa but is been grown throughout southern Asia since ancient times as a vegetable and fodder crop. Guar has been cultivated in India and Pakistan for ages for use of its tender pods as fresh vegetables and other parts of the plants to be used as cattle feed. The plant is extremely drought‐resistant, being able to absorb efficiently all ground water. It grows therefore easily in those semi‐arid regions where less hardy crops perish. The major world supplier of guar seed are India, Pakistan and United States. 

The guar bean is principally grown in India and Australia, with smaller crops in the US, China, and Africa. In India, Rajasthan, Gujarat and Haryana are the main producing regions, and Jodhpur, Sri Ganga-Nagar and Hanumangarh in Rajasthan are the major Guar trading markets. 

India produces 1.2-1.5 million tons of guar annually, making it the largest producer with about 80% of world production. In Pakistan, Punjab is the main production area for guar beans. 

The world production for guar gum and its derivatives is about 0.7 million tons (700,000 tons). Industrial guar gum accounts for about 45% of the total demand. It is used as a controlling agent in oil wells to facilitate easy drilling and prevent fluid loss

Processing Flow Chart

5.1 Undehusked Guar Splits
  The gum is commercially extracted from the seeds essentially by
  a mechanical process of roasting, differential attrition, sieving and polishing.
  The seeds are broken and the germ is separated from the endosperm.
  Two halves of the endosperm are obtained from each seed and are known as Undehusked Guar     Splits. 

5.2 Refined Guar Splits
Refined Guar Splits are obtained when the fine layer of fibrous material, which forms the husk, is removed
and separated from the endosperm halves by polishing. 

5.3 Guar Powder
The refined Guar Splits are then treated and finished into powders by a variety of routes and processing
techniques depending upon the end product 

5.4 Guar seed Extract
Guar seed consists of three parts, germ (43-47%), endosperm (35-42%) and the husk (1 17%). Extracts from Guar
seed include Guar Split/Gum (29%), Korma (30-35%) and Churi (35-40%). Guar split/gum is further refined to Guar
powder. The by-product of Guar Gum industry consisting of the outer seed coat and germ material is called
guar meal. The Guar meal after gum Extraction is a potential source of protein and contains about 42% crude
protein, which is one and a half times more than the level of protein in guar seed. 

5.5 Guar gum & Splits

Approximately 90% of total Guar produce is used for production of Guar Gum and rest is used for culinary
purposes and cattle feed etc. Guar gum, also called guaran, is a galactomanan. Guar gum is produced from
the endosperm, which is about 35-42 percent of the guar seed mass, and mainly consists of gum Poly groups of
monogalactoses (a type of sugar). Different grades are made based on purity and present viscosity of powers in
water. Guar gum has almost 8 times the thickening power as corn starch, and is used in dressings, sauces, milk
products, and baking mixes.
