Two pounds of flour was evenly distributed on a 60 30 2.5-
cm aluminum pan approximately 0.5 cm thick. Then, flour was
placed in a convection oven (Whirlpool, St. Joseph, MI) and heated
either at 90 C or 125 C for 15, 30, and 45 min. After heating, flour
was cooled to room temperature and rehydrated to approximately
12% moisture content in a fermentation cabinet.
