Dormancy of barley belongs today to the parameters of malting barley quality evaluation. The following malting barley varieties were assessed - Jersey, Kompakt, Scarlett, and Tolar, since 2002 a new variety Prestige and in 2004 also the variety Malz, they are the supporting malting varieties. Samples were selected based on the following quality parameters: germinative capacity of barley is higher than 96% and protein content in barley is from 10 to 12% in dry matter, in 2004 however the bottom limit was lowered to 9.5% due to generally lower protein content in barley. Intensity of barley dormancy was checked by determination of germinative energy on...

This review deals with a survey of hop substances with estrogenic effect, their structures, biosynthesis and their fate during brewing process.Main attention was done to 8-prenylnaringenin and its precursor - desmethylxanthohumol. Determination of these substances and determination of their estrogenic effects is discussed in this paper. Preparation of food supplements based on hop is discussed, too.This review deals with a survey of hop substances with estrogenic effect, their structures, biosynthesis and their fate during brewing process.Main attention was done to 8-prenylnaringenin and its precursor - desmethylxanthohumol.
