摘要：The eating quality of various rice species was tested. The cocked rices were classified in 2 grades with its stickiness from superior quality (very sticky) to “poor quality (a little sticky)”. 1. Rices of“superior quality” are Norin No.1, Koshihikari, Koshiziwase, Yatikogane and Koshisakae. 2. Rices of “poor quality” are Norin No.43, Nihonkai, Fuzisaka No.5, Shin No.7, Norin No.41, Hokuriku No.52, Mihonishiki and Tangin. A Starch-iodine blue test as a quality indication of rice was presented. The white rice put into a metal wire basket was heated at 95-97°C in a definite amount of water and the dissolvod soluton was submitted to a starch-iodine-blue test. Varieties giving lighter color were Norin No.1, Koshihikari, Yatikogane, Koshiziwase, Koshisakae, while varieties giving deep blue color were Yoneyama, Shin No.7, Norin No.41, Hokuriku No.52, Tangin and Mihonishiki. A good correlation was found between the results of the proposed method and the eating quality.
