Experimental trials were carried out with brown wheat flour (cv.Bologna), which can be considered as type 2 according to Italian flourclassification legislation (i.e. approx. 85% of extraction yield, maximumash content=0.95 g/100 g dm). The flour was processed with a stonegrinding mill and a sieve (two consecutive passages through a1,100–1,200 μm sieve) at the Molino Paciscopi (Montespertoli,Florence, Italy). Two batches of Bologna brown flour from the sameyear and geographical area (Montespertoli, Florence, Italy) were usedin the two trials; their composition is reported in Table 1.
