In the previous paper, the authors reported on the material change in rice by polishing and the availability of each component in it. It is a noteworthy fact that the loss by scattering of rice bran is small but that by the crushing of rice grains is large.The difference between the polishing ratio calculated on 1000 grains weight and that on total weight is named unavailable ratio of polishing, and this ratio corresponds to the essential loss which is to be taken into account. It is expressed by the following formulae and varies with the polishing rate, so that it is 5% and about 2.6% at 70% and 80% polishing ratios respectively. d=unavailable ratio of polishing=0.003 x^2+0.072 x. x=100-polishing ratio calculated on total weight The curve illustrating this relation is most useful for the control of rice polishing. The unavailable ratio of polishing and the change of each component do not vary with the sort of rice.
