The article deals with the relation of flocculation to the contents of mannan and glucan in the walls of cells of Saccharomycec carlsbergensis yeast used in continuous brewing process. The results of research works confirm that there is a relation between the mannan percentage and flocculation properties. No firm relation could be traced for glucan, but mannan to glucan pro portion increases with the decreasing flocculation properties of yeast. The absolute values of mannan to glucan proportion were 2,7 - 4,0 yeast grown under aerobic conditions and 1,5 -1,9 inyeast grown under anaerobic condition. The figures for periodic fermentation are 1,5 - 1,8.

Polyphenol substances contained in malt and hops have an important role in the brewing process. It is therefore necessary to apply for their determination reliable methods. The authoresses outline briefly the history of methods which are used at present in brewing industry for the determination of polyphenols and antocyanogens, criticize their weak points and recommend to replace them with modern ones. Only methods recognized by international conventions on analytic methods should be used. The methods elaborated by Jerumanis meet all requirements and will be dealt with in a separate article. Beside fundamentals of methods and technique employed for...

The authors have studied in a series of comparison tests the efficiency of various deformers used in yeast plants to defoam mash. They specify the requirements which must be met by good defoamers and recommend several Czechoslovak and foreign products of well proven quality.(In Slovak, English summary only)
