Guar Gum Split is refined endosperm derived from guar seed or cluster bean (cyamoperm tetragonoloba). It is a non ionic polysaccharide galacomannan. Guar Gum Refined Split (Endosperm) is mechanically separated from guar seed which yields 28-30% of Refined Split.

Guar beans are harvested and dried following the growing season. The beans are shelled from the pods, the germ and hull removed. The resulting splits are wet-milled into powder; the powder is graded by granulation and quality.

Products are re-blended according to specification, bagged and marked. Surprisingly, although guar primarily is grown for its gum content, very little was known about the variability of gum content in the seed of Cyamopsis tetragonolobus.
