Kvasny Prum. 1966; 12(2): 25-27 | DOI: 10.18832/kp1966005 
The article outlines several problems which had to be solved in1965 inconnection with the changing organization and structure of the brewing and malting industries inCzechoslovakia. The last year9s results can be classified as very favourable. The target in production was overfulfilled by 40 million crowns, the target in profit by 30 milion. The article describes leading principles on which the plans of the two industries, elaborated for the fourth five - year plan, are based. The plans take duly into account the progress of science and technology, as also important specific features of brewing...

High and uniform quality of filter plates is a vital condition for efficient filtering. By applying methods which have been introduced in paper industry it is possible to estimate very accurately the strength, homogeneity and permeability of plates. The reproducibility of results obtained by applying t described methods has been ascertained in a series of experiments.(In Czech, English summary only)
Making yeast from concentrated mash.Peer-reviewed article
E. PIŠ
Kvasny Prum. 1966; 12(2): 37-39 | DOI: 10.18832/kp1966007
The article deals with the effect of mash concentration upon the yield of yeast, taking into account differing osmotic conditions, availability of nutrients - including oxygen - important for the propagation of cells etc. The Vogelbusch method and its modifications characterized by using extremely concentrated mash are discussed in detail. The method secures high yields and outstanding productivity. The results obtained at the Bitole yeast plant fully confirm the merits of the method.(In Slovak, English summary only)
Determination of carbonyl compounds in wine.Peer-reviewed article

The article deals with a polarographic method which has been developed for determining carbonyl compounds in wine. The method is based on the reduction of semicarbazones. The results of ten analyses covering ten different sorts of wine fit very well the results of iodometric analyses. The method enables to determine all volatile carbonyl substances which are shown as acetaldehyde within 45 minutes. The described method is reasonably accurate and can be recommended for routine analyses.(In Czech, English summary only)
