| Description
| - Antioxidační aktivita chmele byla měřena v průběhu sušení, granulace a skladování monitorováním poklesu absorbance stabilního radikálu 1,1-diphenyl-2-picrylhydrazylu (DPPH) v horkovodních chmelových extraktech. Vzorky chmelů byly odebírány v různých fázích zpracování sušeného chmele. Bylo zjištěno, že část antioxidační aktivity se nevratně ztrácí při sušení. Sušení v komorové a pásové sušárně je z hlediska konzervace antioxidačních vlastností chmele srovnatelné. Mletí sušeného hlávkového chmele a následná granula-ce nemají prokazatelný vliv na antioxidační stav chmele. Antioxidační aktivita chmele klesá v průběhu stárnutí v závislosti na teplotě a formě chmele (hlávky, balené granule). (cs)
- Total antioxidant activity of hops was measured in the course of drying, pelletizing and storage by monitoring the loss of optical density of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical in hot water hop extracts. Samples were withdrawn at different phases of green hops processing. A part of antioxidative activity of hops is irreversibly lost in the course of drying. The loss does not usually exceed 5 % of origin antioxidant activity value. Drying in belt and chamber kilns are comparable from the point of view of hops antioxidative properties conservation. Grinding and pelletizing has no conclusive effect on antioxidative status of hops. Antioxidative activities of hops declines in the course of long-term storage in dependence on storage temperature and hop form (raw hops, pellets). Storage temperature has no effect on antioxidative activity of hop pellets packed in multi-layer foil without air access.
