Application of polarographic methods to analyses of albumins in malt and determination of their effect upon the beer stability.Peer-reviewed article
J. HUMMEL
Kvasny Prum. 1963; 9(5): 106-109 | DOI: 10.18832/kp1963016
The article deals with the first so far known example of new application of polarographic methods, viz. for ascertaining the stage of proteolysis in green malt. Various samples of germinating barley processed, i. e. cryied, crushed and extracted in the same way, have been studied, Different stages of proteolysis are reflected in the polarographic maximum of cobalt.(In Czech, English summary only)
Effect of hop resins upon beer bitter.Peer-reviewed article
M. VANČURA, J. BEDNÁŘ
Kvasny Prum. 1963; 9(5): 110-112 | DOI: 10.18832/kp1963017
The results of laboratory analyses indicate, that the bitter taste of beer is caused mainly by soft resins. Hard resins participate more significantly only in hops used after a long storing. It has been confirmed that for fresh hops the proportions of £+β/3. After a prolonged storing the effect of β - components is more pronounced.(In Czech, English summary only)
Continuous fermentation.Peer-reviewed article
M. KAHLER
Kvasny Prum. 1963; 9(5): 113-116 | DOI: 10.18832/kp1963018
By introducing semi-continuous methods the time required for main fermentation can be reduced by 30 % and initial capital investments by 50 %, improving at the same time the utilization factor of the room occupied by fermenting installations also by 50 %. The continuous method shortens the after-fermentation stage by approximately 65 %. The cycle required for brewing beer takes no more than 10 days.(In Czech, English summary only)
Chromatographic determination of high molecular albumins in brewing worts.Peer-reviewed article
V. KAREL
Kvasny Prum. 1963; 9(5): 117-119 | DOI: 10.18832/kp1963019
The article deals with a new modification of chromatographic methods developed by Raible for determining high molecular albumins in brewing worts. The method was applied in the research works studying the effect of boiling upon the high molecular albumins present in worts in the infusion stage as also to changes taking place in the high molecular albumins during the brewing process.(In Czech, English summary only)
Experiments - an integral part of research works.Peer-reviewed article
G. KLAZAR
Kvasny Prum. 1963; 9(5): 119-122 | DOI: 10.18832/kp1963020
The article demonstrates and evaluates the important role of the experimental part of research works. Experimental results verify the theoretical conclusions and provide a reliable base for applying the results in industry. Main problems, on which the experimental research work is at present concentrated are briefly outlined and some new experimental methods described.(In Czech, English summary only)
Selecting and testing best varieties of brewing barley.Peer-reviewed article
M. SVĚDIROHOVÁ, M. TRKAN, H. VRTĚLOVÁ
Kvasny Prum. 1963; 9(5): 122-124 | DOI: 10.18832/kp1963021
The article deals with the methods employed for selecting barley varieties suitable for malting and with the system of classification reflecting their malting properties. The results of analyses made in 1961 confirm, that the best variety of barley frown inCzechoslovakiais "Valtický", though the quality of other popular varieties is also very high. Average figures demonstrate, that Czechoslovak brewing barley is in every respect superior to any foreign product.(In Czech, English summary only)
