WHITENING OF KICE.

grain contains in its dry matter less resp. only a little more 
starch than the raw rice, whereas we might have expected, on 
account of the general richness of the bran in albuminoids, 
fat, and fibre, that in the grain freed from the bran there would 
be found less fibre and more of carbohydrates than in the 
original hulled rice. 
The subject under discussion was experimented on in our 
laboratory by Mr. S. Tanaka, who, under his immediate 
superintendance, had 23.929 kilograms of the famous rice 
from the province of Mino, whitened by manual labour. The 
products were weighed soon after the cleaning, and were found 
to contain, per cent of the grain applied : 
VI hitened Rice.91.05% 
Bran . 7.37 „ 
Broken grain. 1.69 „ 
Total.100.11 „ 
The slight increase of the weight (0.11%) must certainly 
be due to water, attracted by the powdered materials from 
the air. 
A second trial was made by Mr. F. Kobayashi, who applied 
a medium sort of rice, grown in the province of Echiu, and who 
obtained from 100 parts of raw grain : 
Whitened grain.91.92% 
Bran . 7.16,, 
Broken grain. 0.50 „ 
Hull, waste products, etc. 0.30 ,, 
Total .99.98,, 
The results of the two trials very nearly coincide with 
each other as well as with Eijkman’s figures. Calculated fin- 
100 parts of dry matter applied in the form of raw grain, the 
following quantities were obtained by the cleaning :
