The guar gum splits is basically the endosperm part of the guar seed which is commercially extracted from the seeds by a mechanical process of cracking, roasting, differential attrition,
sieving and polishing. The seeds are crack opened and the germ is separated from the endosperm. Two halves of the endosperm are obtained from each seed and the fine layer of fibrous material, which forms the husk, is removed and separated from the endosperm halves by the process of Dehusking and polishing.
