Sažetak

The research was aimed at determining the effect of malting time of grain of selected varieties of brewing barley cultivated in Poland on the quality of Pilsner type malts, with consideration given to their extractivity and natural losses. The experimental material was barley grain of the following varieties: Class, Blask, Riviera, Lailla, Hanka,
Sebastian, Bolina, Philadelphia, Tolar, and Stratus. Grain fractions of >2.5 mm were used to produce 4, 5 and 6-day Pilsner type malts under laboratory conditions. The grain, malt and the resultant worts were evaluated and determined for the malting usability acc. to Molina-Cano. Analyses demonstrated that the 4, 5 and 6-day malting of barley grain enabled obtaining malts with functional parameters corresponding to standard values. Elongation of the malting time
from 4 to 6 days does not elicit any significant changes in the extractivity of malt, nor in the malting usability of grain,
however it increases natural losses of the malted matter.
