Rice contains much more starch, but on the other hand, much less
albuminous matter and ash, than maize and barley. The compositions of
different kinds of dried rice do not vary very much, but as the amount
of moisture in the raw grain ranges from 5 to 15 per cent., no brewer
ought to buy rice without having first of all inquired with the
assistance of a chemist as to the percentage of water present in the
sample.

Another point requiring attention is that of taking notice of the
acidity, which also varies a good deal for different sorts of rice. In
comparing the nutritive values of the three kinds of grain before us,
Pillitz obtained the following numbers:
