The middlings form the inner coating of the wheat grain, next the
floury or starchy portion, and contain particles of the germ and a
larger percentage of carbohydrates than either shipstuff or bran, and
a less proportion of fiber, while the percentage of albuminoids
usually stands between that of shipstuff and bran. The following data
are obtained from the 4 lb. procured from a bushel of wheat:

Lb. per Bushel
of Wheat.
Water. 0.562
Ash. 0.138
Albuminoids. 0.657
Woody fiber. 0.142
Carbo-hydrates (starchy matters). 2.307
Fat. 0.193


SHIPSTUFF.

That part separated and known as shipstuff is a very thin layer next
outside of the middlings, and contains the germ not found in the
middlings or left as a part of the flour. The quantity produced, 2 lb.
from a bushel of wheat, is very small and rarely kept separate from
the bran. The following shows the analysis:

Lb. per Bushel
of Wheat.
Water. 0.282
Ash. 0.101
