Evaluation of alfa-amylase activity in malt made from selected barley varieties intended for beer production
Original language description
Activity of alpha-amylase enzyme (EC 3.2.1.1) is considered to be primarily essential for barley?s (Hordeum vulgare L.) seed germination and crucial for malting and beer processing. The aim of this study was to evaluate: (i) the activity of alpha-amylaseenzyme in spring barley varieties recommended for Czech Beer production (Bojos, Malz and Tolar) compared with varieties intended for malt export (Kompakt, Jersey and Sebastian) harvested in 2007-2008; (ii) the effect of zinc foliar application (dose of0.5 kg/ha Zn) during pre-harvest period on the activity of this enzyme; (iii) relations between alpha-amylase activity and selected qualitative parameters (TGW, extract, friability etc.). The enzyme activity was assessed by the colorimetric method (EBC 4.13). The least activity of alpha-amylase enzyme (expressed by dextrinizing units ? DU/g) was established in Tolar variety, the export varieties Kompakt and Jersey belonged to the group with high enzyme activity.
