Studies on starches of wild plants in Japan. Part 18. Starches from Hama-nata-mame(Canavalia lineata DC.), Suisen(Narcissus tazetta Linn. var, chinensis Roemer), Hama-suge(Cyperus rotundus Linn.) and Ki-ebine(Calanthe Sieboldii Decne.).

Starch samples were prepared from the following: the root of Hama-nata-mame, Canavalia lineata DC. (Leguminosae) ; bulb of Suisen, Narcissus tazetta Linn. var. chinensis Roemer (Amaryllidaceae) ; tuber of Hama-suge, Cyperus rotundaus Linn. (Cyperaceae) ; and rhizome of Ki-ebine, Calanthe Sieboldii Decne. (Orchidaceae). Their yields were 7, 9, 14, and 13%, respec-tively. These starches were examined as to granular size and shape, phosphorus and protein con-tents, the X-ray diffraction pattern, iodine coloration, swelling power, solubility, amylogram, the digestibility of the raw starches by glucoamylase, and other properties. Starch granules of Hama-nata-mame were small in size, having high whiteness and high swelling power. Suisen starch was in swelling or dissolving at 60°C already. Hama-suge starch granules had a complicated shape and properties similar in gelatinization to sweet potato. Ki-ebine starch had a thin shape and low swelling power ; the viscosity on amylogram also was the lowest.
