A review on the development of extrusion technique and its possible applications in brewing is made in the article. Experiments were performed with the one-screw extruder (Brabender) and with the two-screw extruder (made in GDR). For extrusion the green malt and barley were used. Malts and beers prepared showed higher viscosity and longer time-period tor the straining. The optimum results were achieved with 50 % of surrogation by extruded substrate with the addition of other materials. The extrusion proper seems to be a suitable process partially replacing kilning.(In Czech, English summary only)

The alcohol resistant strain of the yeast Saccharomyces cerevisiae 6C have been used in a production of sparkling wines. Analytical and sensorial determinations have been made during the after-fermentation and the wine ripening in the time interval of 380 days. Another fermentation was inoculated with the preparate active dry wine-making yeasts Hefix 2000. During the principal fermentation the substrate was dissimilated. During the process of ripening the significant changes in concentrations of succinic and acetic acids were observed. The content of protein and the whole amino acids pool in ripened sparkling wines has been increased. Higher concentrations...
