By means of polyamide powder flavonole glycosides were separated from a large group of polyphenolic substances and analysed. Besides qualitative analyses semiquantitative methods were applied, too to estimate approximate percentage of various components. Individual components were identified by means of two-dimensional paper chromatography. Analyses of 50 hop varieties indicate that in a large majority of the Czechoslovak and other European varieties (with one exception, viz. English variety New Variety Bullin Q 43) the composition of the glycoside group is practically the same, whereas Americal varieties are distinctly different and have in this respect...

To verify the conclusions derived from some recent research works experiments were made with introducing the steeping operation straight into the scheme employed in production lines incorporating shifting heaps. In the first stage lasting 6 hours a batch of barley was steeped, washed and brought to the 31 % moisture content. Spraying in the shifting heap raised the moisture content to 43 %. The described steeping method permits to reduce substantially the water consumption by some 50 %, preserving the required quality of malt and to save more than 2 million crowns in capital investments on a malt-house with 30 000 t per annum capacity.(In...
