Subaleurone Endosperm Cells of High Protein Content.

Subaleurone and inner endosperm in the coarse (over 35 micron) air-classified fractions of flour milled from hard red winter (HRW) wheat had average protein contents of about 45 and 11%, respectively. The protein contents of subaleurone and inner endosperm, separated from coarse fraction of pin-milled HRW flour by sedimentation in nonaqueous liquids, ranged 33-54% and 8-15%, respectively. Cells of subaleurone endosperm were reduced to particles below 35-micron size less readily than were cells of inner endosperm; in consequence, subaleurone endosperm cells concentrated in the coarse air-classified fractions, and raised the protein content of the latter.
