Present analytical methods of malt checking do not allow to judge sufficiently quality of the malt from point of view of its suitability for the use in brewery. EBC Analytical Committee works out the new methods, e. g. new TEPRAL method of mashing instead of recent congress method, which should imitate better the situation in a plant. In this communication the methods determinating final attenuation degree are evaluated and the method suggested by LVB, including the laboratory equipment, is described. Further the method of boiling colour determination is explained, which is another analytical value important for prediction of the final product quality....
Technical Conditions of the Cleaning Plant Installation and Operation.Peer-reviewed article
A. KRATOCHVÍLE
Kvasny Prum. 1981; 27(3): 53-57 | DOI: 10.18832/kp1981010
The article deals with the selected ingeneering problems concerning installation and operation of the cleaning plants. Sizes of thee separate tanks, correlations among the required flow rates for the standard types of a station and a method for determination of the pump parameters are presented. Finally the principal thermally-technical aspects are given. Some numerical values are listed in tables.(In Czech, English summary only)
Information obtained by studying phenolic compounds in smoked malts ordered.Peer-reviewed article

The results presented in this report should precize the method of phenolic compound estimation in smoked malt since its description rendered by the firm Suntory has not given full particulars. Owing to that it was necessary to work out single steps of sample preparation, chromatographic process and its evaluation to obtain the optimal results. The most suitable conditions of gas chromatography are as follows: FFAP column (10 % ) on Chromosorbe HMDS (60-80 mesh), column length 1,5 m, diameter 4 mm, column temperature 70 to 250°C (10 °C/min), injector temperature 300 °C, detector FID, detector temperature 300 °C, carrying gas - nitrogen. Flow rate of...
Amino acids produced by fermentation processes from unconventional carbon sources.Peer-reviewed article
J. PELECHOVÁ, J. PLACHÝ, F. SMÉKAL
Kvasny Prum. 1981; 27(3): 64-68 | DOI: 10.18832/kp1981012
The authors present in the article all information so far published in patents and available literature dealing with the production of amino acids by fermentation from unconventional sources of carbon, as e. g. methanol, ethanol, acetic acid and hydrolysates of some lignocellulose materials.(In Czech, English summary only)
