After the beans have been threshed, the guar seeds are delivered to a split manufacturer. There, a thermo-mechanical process separates the endosperms (splits) from the germs and the husks. The germ (guar meal) is valued as a high-protein animal feed. Guar gum is manufactured from the splits in a milling process.Guar seeds contain approximately 37 per cent of galactomannan.
The Polygal Group purchases both splits and guar gum for its production facilities.
