    Solution

    Thickening agents, or thickeners, are substances which, when added to an aqueous mixture, increase its viscosity without substantially modifying its other properties, such as taste. They provide body, increase stability, and improve suspension of added ingredients. Examples of thickening agents include: polysaccharides (starches, vegetable gums, and pectin), proteins (eggs, collagen, gelatin, blood albumin) and fats (butter, oil and lards). All purpose flour  is the most popular food thickener, followed by  cornstarch  and  arrowroot  or  tapioca.  All of these thickeners are based on starch as the thickening agent.
