Technologické možnosti výroby ciderů a sladinových kvašených nápojů
Sojka, Jakub
This thesis is mainly devoted to the production of cider, which has been booming in the Czech Republic in recent years. Emphasis is put on the selection of suitable varieties of apples as well as on the whole technological process of production, from fermentation and ripening to product bottling. The production process is enriched with knowledge from wine-making practices, which could be a useful aid to achieve first-class quality and product diversity, especially regarding the knowledge of maceration and maturing using wood. Part of the thesis is also devoted to malt fermented beverages. It describes the process of making malt and fermentation using brewing yeast. Subsequent treatment options after fermentation and ripening are the same as for ciders and this after-fermentation treatments are associated and valid for both types of beverages. The practical part is devoted to the production of samples of cider and malt fermented beverages. The impact of both apple varieties and brewing/wine yeasts on the sensory quality of ciders is investigated. The last part is devoted to the possibilities of flavoring malt fermented beverages. Sensory analysis was performed on all samples and HPLC analysis was performed on selected samples.
