Guar Gum acts as a thickening agent in dressings and other recipes
Guar gum, also called guaran, is extracted from the seed of the leguminous shrub Cyamopsis tetragonoloba, where it acts as a food and water store. It’s similar to locust bean gum. Guar gum is a polysaccharide (a long chain of sugars) made of the sugars galactose and mannose. This long chain acts as a thickening agent in dressings and other recipes, particularly where heating is not desired. Guar gum is not usually sold in markets, but some health food stores and drug stores carry it, as do some coops.
