WebIodine is well-known for the iodo-starch reaction under which a blue color develops and, as a nutrient, contained in various seaweeds. Since iodine is an element, it can not be obtained through a chemical synthesis and there being no other way to produce it than to extract from the natural resources containing it, we can say that iodine is valuable material. Webusing a color reaction of hydrolysate of starch with phenol-sulfuric acid or perchloric acid-anthrone (Michel et al. 1956, Clegg 1956). These reactions are conducted after the isola-tion of starch from plant materials and an enzymatic hydro-lysis of starch. These processes are laborious and time consuming. An iodo-starch method is a rapid and ...
