Breakage of Endosperm Cell Walls in Flour Milling.

W. E. Schulze and M. M. MacMasters. Copyright 1962 by the American Association of Cereal Chemists, Inc. 

Particles of cell walls from the starchy endosperm occur with more or less of the cell contents, or with none, in hard red winter wheat flours. The cell-wall particles are always portions of walls of two adjacent cells, with the middle lamella which cements them. Breakage of the cell walls is invariably transverse, rather than along the middle lamella. This conclusion is compatible with known structure, composition, and physical properties of plant cell walls.
