Gum Fun: Investigating Plant Gums

Plant gums are often used in the food industry as thickening and stabilising agents. Gums are water soluble polysaccharides, such as starch and cellulose. In this activity, students investigate what happens to the texture when different polysaccharides are mixed.

When solutions of some polysaccharides are mixed, they interact with each other. This can result in an increase in viscosity, which becomes greater than each solution individually. Under certain conditions, they may even form a gel.
