Classification of barley and sorghum malts according to their
amylase activity levels. a-Amylase (A) and /3-amylase (B) activities were
assayed as described under Experimental. The malts were classified into
seven classes according to their enzymatic level (in milligrams of maltose
per milligram of malt) as follows: class 1 (0.0 < amylase activity < 0.1),
class 2 (O.I < amylase activity < 0.2), class 3 (0.2 < amylase activity
< 0.3), class 4 (0.3 < amylase activity < 0.4), class 5 (0.4 < amylase
activity < 0.5), class 6
