The food thickeners are the modified food starch, polysaccharide or certain vegetable gums. When a food thickener or a thickening agent is added to beverage, it absorbs the fluid and the fluid thickens. Breaking down the starch reverses the thickening action and almost all water in the beverage is available as free fluid for absorption by the body. If the thickening agent is a vegetable gum, it will continue to hold water even during digestion. Thus a vegetable based thickening agent may reduce fluid availability to the body. Commonly used thickening agents are pectin, lignin, algin, gums and agar-agar.
