| Description
| - Effect of technology of fermentation, filtration and colloidal stabilization on phytoestrogen content in beer examined in model brewing and fermentation process. Phytoestrogens assessed by method using HPLC-MS. Commonly used technologies of fermentation and beer maturation were comparable in terms of phytoestrogen losses between wort and beer. No significant differences in effect of used filtration materials on phytoestrogens in filtrate detected. Pasteurization does not affect phytoestrogen content in beer. Stabilization treatment with a sorbent of proteins is applicable for colloidal stabilization and for phytoestrogen kontent. Stabilization with polyphenols sorbent or combination of both types of sorbents is not suitable due to high phytoestrogen losses (25 to 35 % in comparison to non-stabilized beer). Phytoestrogen losses between wort and beer are substantial. Decrease of mentioned markers of phytoestrogens was 45 to 60 %.

- Modelově zkoumán vliv technologie kvašení, filtrace a koloidní stabilizace na obsah fytoestrogenů v pivu. Fytoestrogeny stanoveny vypracovanou metodou pomocí HPLC-MS. Běžně používané technologie kvašení a zrání piva (dvoufázové technologie spilka-sklep, CKT-sklep, jednofázové kvašení v CKT) jsou z hlediska ztrát fytoestrogenů mezi mladinou a pivem srovnatelné. Nezjistily se prakticky významné rozdíly v účinku hlavních filtračních materiálů, křemeliny a filtračních desek na bázi celulózy, na obsah fytoestrogenů ve filtrátu. Pasterace neovlivňuje obsah fytoestrogenů v pivu. Pro koloidní stabilizaci piva je z hlediska zachování obsahu fytoestrogenů použitelný stabilizační zásah sorbentem bílkovin. Stabilizace sorbentem polyfenolů nebo kombinací obou typů sorbentů je nevhodná z důvodu vysokých ztrát fytoestrogenů, které činily zhruba 25 až 35 % oproti nestabilizovanému pivu. Ztráty fytoestrogenů mezi mladinou a pivem jsou značné. Úbytek sumy sledovaných markerů fytoestrogenů činil přibližně 45-60 %. (cs)
