Description
A beady starch obtained from the tuberous roots of the cassava plant, Manihot esculenta, native to tropical America. The roots are leached then dried and ground. Cassava, or tapioca, starch has irregularly shaped kernels. It is composed of 20% amylose. Tapioca starch is the predominant starch used in Latin America. When heated with water, tapioca forms a thick stringy solution that gets thinner with heating time. It thickens only slightly on cooling to forms a translucent gel. Tapioca is used for laundry starch, cooking and as an adhesive for stamps, envelopes, labels and plywood.
