Silica gel made in Czechoslovakia by development laboratories at Michalovce, belonging to Keramické závody N.C., can be used with good results for stabilizing filtration of beer, since it has very satisfactory filtering and stabilizing properties. The authors evaluate the results of a special treatment in which homogeneous, aqueous suspension of proteolytic enzyme and silica gel were used in certain doses to influence filtration through diatomaceous earth filters. Filtration layer consisting of the mentioned components served for stabilizing filtration in which a mixture of various sorts of diatomaceous earth was used in due proportion. The method...

The article deals with new trends in yeast industry and yeast utilization. In plants manufacturing bakery yeast prevails now fermentation in concentrated nutritive media, reliable control of fermentation conditions and application of strains and started ensuring rapid propagation. Owing to new technologic processes used in sugar industry molasses has lost much of its qualities and must be now used only with growth stimulators. Fermentation is carried out mainly in bath-type fermenters the design of which ensures free access of large quantities of oxygen. From manufacturing point of view the most decisive factor is energy balance. Since the genetic...
Modern method of processing black-skinned grapes.Peer-reviewed article
