Arrow-root starch is a product manufactured from the underground parts of a number of differ- ent plants grown in tropical and subtropical coun- tries. It is valued principally as a food for invalids, especially in cases of persistent diarrhea and dysentery. In South Africa and the East Indies, Maranta aruiidinacea (Fig. 284) is the plant most commonly cultivated for this purpose. This is much grown in the Bermuda islands, and therefore is commonly known as Bermuda arrow-root. In Aus- tralia, Maranta nobilis, Manihot utilissima (cassava) and several species of Canna,—C. Achiras, C. glaaca, C. edulis, and others,—are used for the same purpose, and C. flaccida, a native of the south- ern part of the United States, is one of the most profitable species. Recent experiments show that the common canna used in this country for decorative purposes (C. Indica, Indian shot) can be made a profitable source of arrow-root in all the southern states. In the Pacific islands, especially in Guam, the Hawaiian islands and the Philippines, -Tacca pinnatifida, a plant belonging to the Taccacese and closely related to the yams, is more commonly used, and to a considerable extent also in India. Both the marantas and the cannas have fleshy rhi- zomes, while the cassava and the tacca have fleshy roots resembling sweet-potatoes. Cassava starch is considered the best for laundry purposes and is much used by manufacturers of linen goods. Some varieties of this plant received recently from Colombia, South America, yield as much as 39 per cent of their weight as starch. Manufacture.—From whatever source the arrow- root may be derived, the process of manufacture is practically the same. The fresh roots are washed a
