Processing of Guar Seeds to make 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. When the fine layer of fibrous material, which forms the husk, is removed and separated from the endosperm halves by polishing, guar splits are obtained and the yield of the same is ranging from 27-29%. The hull (husk) and germ portion of guar seed are termed as guar meal (guar protein) and the yield of the same is ranging from 70-72%.

Processing of Guar Splits to make Guar Gum Powder: The guar splits are made refined by sieving and sorting processes. Refined guar splits are then treated and finished into powders (known as guar gum) by a variety of routes and processing techniques depending upon the end product desired. The basic process included hydration of refined guar splits, flaking, grinding drying followed by sieving and packing.

Guar Gum Powder: It is a galactomannan polysaccharide, has a chain of (1→4)-linked-β-D-mannopyranosyl units with single α-D-galactopyranosyl units connected by (1→6) linkages to, on the average, every second main chain unit.
