grown in central Poland (DANKO, Plant Breeding Co., Laski, Poland)
in 2005, based on the grain quality parameters. Samples were tempered
to 14% moisture and milled on a Quadrumat Senior laboratory
mill (Brabender GmbH & Co., Duisburg, Germany) to obtain
straight grade flour with extraction rates of 100% (F-100%) and 92%
(F-92%), respectively. White wheat flour with an extraction rate of
70% (F-70%) was purchased froma local commercial grocery.
