The present investigation was undertaken in order to examine the influence of physical properties of brown rice on polishing efficiency. A SATAKE model DB-16 polishing machine (Roll diameter : 16.5 ingh, Roll mesh : No. 46 and 60) was used for all polishing. The data (13 varieties, n=213) obtained were treated by statistical methods.1. The relationships between polishing ratio(60.0 to 84.9%) and polishing efficiency was highly significant. The correlation was 0.331.^⁢**>2. The various physical properties of brown rice, i.e., rigidity, standard deviation of rigidity, weight of 1000 grains, moisture, and trashy grain ratio had significant correlations with polishing efficiency. And as simple two-variable correlation coefficients were obtained between rigidity and weight of 1000 grains (γ=-0.398^<**>) and moisture (γ=-0.307^*), it seemed reasonable to assume that the rigidity is related to polishing effeciency.3. Rigidity had relations with polishing efficienvy. The optimum range of rigidity for high polishing efficiency was about 5.5 to 6.0. Standard deviation of rigidity and trashy grain ratio correlated inversely with polishing efficiency, and the latter relation was significant at the 5% level.4. Differences were found to be highly significant among the varieties of rice in regard to polishing efficiency by means of significant test for averages.
