Introduction

Guar gum, also called guaran, is a substance made from guar beans which has thickening and stabilizing properties useful in various industries, traditionally the food industry and, increasingly, the hydraulic fracturing industry. The guar seeds are dehusked, milled and screened to obtain the guar gum. It is typically produced as a free-flowing, off-white powder. It is classed as a galactomannan.
