A sensory aging of beer occurs during the beer transport to a customer and its storage; this is due to irreversible chemical processes and is manifested by adverse change in the organoleptic character of the beer. Sensory beer aging results in the evolution of the old flavor of the beer, which is a combination of many foreign flavors and fragrances. The development of substances responsible for these sensory changes (especially carbonyl compounds) can be affected by storage, particularly by access to oxygen, light, vibrations, and temperature of storage. In our study we selected carbonyl compounds which can be regarded as indicators of aging of Czech...

The review article describes the risks of pathogenic bacteria transfer by drinking water and possible causes of drinking water contamination.In the past occurred several times a contamination of drinking water by pathogenic bacteria, caused mass illness with deaths. In the year 1975in Federal republic of Germany was adopted fi rst law on drinking water (Trinkwasserverordnung). The amendment of this law was in the year2001, next amendments followed in the years 2011 and 2013. This law is governed by regular checks of drinking water sources (drinking waterreservoirs, wells, etc.) to the consumers. Set limits of microbiological...
