Washing and disinfectant agent application posessing most convenient properties for defined conditions is a necessary prerequisite how to attain a higher degree of beer shelf-life. Products of this variety are abound in large quantities and therefore it appears necessary to perform their evaluation. A range of criteria is being assessed for this purpose (washing effect, pH-value, titrimetric acidity, surface tension, complexation ability, conductivity, foaminess, rinsing ability, COD, corrosivity and microbicidal effectivity). The article outlines practical examples of two agents evaluation - alkali and heavy acid ones. (In Czech, English summary only)

The paper summarises basic data relevant to ethanol hop extracts and CO2-extracts preparation and their properties. A special attention is being given to new products with respect to ethanol extracts production since 1989. A mutual comparison of hops, pellets (90 and PUC - types), ethanol and CO2-extracts is presented with respect to their summary resin, α-acids, ß-fraction contents and their mutual proportion, all concerning Hallertauer Northern Brewer, Hallertauer Perle and Hallertauer Hersbmcker Spät species, harvest year 1995. The highest α-acids to ß-fraction ratio was found at CO2-extracts: the remaining...
