Description
Polysaccharide granules obtained from the common white potato, Solanum tuberosum. Potato starch is primarily used as a thickening agent for foods in Europe while Cornstarch is more commonly use in the United States. When heated with water, potato starch forms a thick, gummy solution that becomes thinner with heating time. It thickens only slightly on cooling to forms a transparent gel that dries to a tough resilient film. Potato starch is used to size paper and textiles. It adds strength and tear resistance to paper.
