<p>ISO 3092:2009 specifies the determination of the alpha-amylase activity of cereals by the falling number (FN) method according to Hagberg-Perten.</p>
<p>This method is applicable to cereal grains, in particular to wheat and rye and their flours, durum wheat and its semolina.</p>
<p>This method is not applicable to the determination of low levels of alpha-amylase activity.</p>
<p>By converting the FN into a liquefaction number (LN), it is possible to use this method to estimate the composition of mixtures of grain, flour or semolina with known FNs necessary to produce a sample of a required FN.</p>
