Materials and MethodsSamples of Parboiled Rice. The samples of parboiled and semiparboiled paddv (rough rice) and rice used, in the varieties Bangara Sanna (BS) and Ratna Chudi (RC), have been described (2); they are referred to here by their self-explanatory code numbers. Onlv whole grains, hand-picked from the well mixed and cleaned samples, were used. Cooking Quality. Cooking quality of the rice samples was studied with respect to their water uptake, iodine blue value of the gruel, and solids in gruel (excess cooking water). Five grams of rice were cooked (induplicate) in 70 ml. of dis-tilled water in wide glass tubes immersed in a boiling water bath (bath tempera-ture 98 C.. cooking-water temperature 96 C.) for 30 minutes. The gruel was strained through a sieve and the rice was weighed after quick wiping with filter paper to give its water uptake (grams of water absorbed per gram of rice). Iodine blue value of the gruel was ob-tained, after standing for 2 hours, bv adding 1 ml. of iodine solution (7) to 1 ml. of gruel (in duplicate), diluting to 100 ml., and reading in a Klett-Summer-son photoelectric colorimeter with a 600-mu filter. Solids in the gruel were determined by evaporating to drvness and weighing.
