Comparative analysis of marketing communication of selected craft breweries during 2021-2023
Stanislav, Martin ; Koudelková, Petra (advisor) ; Halada, Jan (referee)
The paper Comparative analysis of marketing communication of selected craft breweries in the years 2021-2023 focuses on marketing communication of microbreweries in the Czech environment. Its aim is to formulate a proposal for improving marketing communication for specific selected microbreweries, but also general recommendations for all others. It achieves this through the results of a content analysis of the three most influential microbreweries in the Czech Republic. In the theoretical part, it deals with the development of the brewing industry in the Czech Republic and puts into context its current state and the position of microbreweries in it. Subsequently, it focuses on the communication aspects typical for microbreweries and presents the barriers in marketing communication that small breweries have to cope with. In the practical part, the bachelor thesis deals with the actual analysis of the communication of the selected microbreweries, on the basis of which recommendations for improving the communication of the studied breweries are subsequently formulated, but also general recommendations that can be followed by small breweries not included in the research. The thesis provides valuable insight into the functioning of microbreweries on social media and can serve as a basis for future...

Transformation of brewery industry waste by carotenogenic yeasts
Šnejdrlová, Kateřina ; Šimanský, Samuel (referee) ; Holub, Jiří (advisor)
Carotenoids are one of the metabolites produced by carotenogenic yeasts. These are valuable substances that are used in the food and pharmaceutical industries. The use of waste and by-product as substrate for cultivation of carotenogenic yeasts can reduce the overall cost of carotenoid production. The by-products of the brewing industry, due to their nutritional composition, appear to be suitable materials for use in the cultivation of microorganisms. The work is divided into theoretical and practical parts. The theoretical part focuses on the description of yeasts, their metabolites and individual substrates. The practical part focuses on the cultivation of carotenogenic yeasts on brewer's spent grain hydrolysate and on yeast extracts prepared from brewer's spent yeast. Following yeasts were used in the practical part: Cystofilobasidium infirmominiatum CCY 17-18-4, Sporidiobolus salmonicolor CCY 19-4-25, Sporobolomyces shibatanus CCY 19-9-6, Rhodotorula kratochvilovae CCY 20-2-26, Rhodotorula mucilaginosa CCY 20-7-31, Rhodotorula toruloides CCY 62-2-4. The results obtained in this work using advanced chromatographic methods suggest that treated brewer's spent grain and yeast extract prepared from brewer's spent yeast are suitable substrates for the cultivation of carotenogenic yeasts. The prepared yeast extract can also serve as a source of total nitrogen during cultivation, without negatively affecting the monitored parameters.

Biogenní aminy v produktech minipivovarů
SYMONOVÁ, Michaela
The bachelor thesis deals withbiogenic amines (BA) content in beers of selected microbreweries from South Bohemia, where beers from commercial breweries are also used for comparison. This thesis is divided into two parts. The first, theoretical part, is focused on introducing the brewing industry, the process of beer production, the difference in the production process in microbreweries and their characteristics. It also explains what BAs are and their different presentation. The second half of this thesis is focused on the experimental part, where the methodology of the work, determination and evaluation of BA content in different beer samples is presented. The ultraperformance liquid chromatography (UPLC) method by which the content of individual BAs in beer samples was determined is also presented. Subsequently, the results of the experiment are presented and a discussion with a comparison of the results of this work with the results of other studies of the same focus is presented.

Brewing industry
Artýszková, Jana ; Illková, Kateřina (referee) ; Omelková, Jiřina (advisor)
The aim of the theoretical part of the thesis is the study and the treatment of the problem of the manufacturing of beer, focused on the czech conditions and classical Czech technology. Within the theoretical part the history of this branch of industry together with the modern methods, enabling greater productivity of beer production, are summarized. Experimental part of the thesis was carried out in a small brewery in Czech republic, producing aproximately 10 000 hl per year. In this brewery the selected parameters were studied not only in the course of cooking and fermentation of beer, but during the output control in racking to the drums and plastic bottles, as well. The studied parameters were as follows: the sugar content of front and wort, the control of microbiological contamination in fermenting cellar and in beer-storage cellar, the content of CO2 by last stage of fermentation and pH- value and color by the end-product.

Barley Proteomic Studies Related to Beer Production
Benkovská, Dagmar ; Márová, Ivana (referee) ; Ehrenbergerová, Jaroslava (referee) ; Zdráhal, Zbyněk (referee) ; Bobáľová, Janette (advisor)
Tato práce se zabývá proteomickými studiemi ječmene v souvislosti s výrobou piva. Ječmen patří mezi nejvýznamnější plodiny na světě a je využíván hlavně pro sladovnické účely, nejčastěji pro pivovarnictví. Studium proteinů ječmene během sladování a výroby piva poskytuje informace o změnách v proteinovém složení nebo jejich posttranslačních modifikacích. Jelikož jsou proteiny v ječmeni a jejich změny zásadní pro kvalitu sladu a piva, proteomické studie ječmene mají potenciál pro zlepšení procesu sladování a pivovarnictví. Hlavním cílem této práce je studium ve vodě rozpustných proteinů ječmene a jejich změn, ke kterým dochází během sladování a výroby piva. Rozdíly v proteinovém složení byly sledovány pomocí gelové elektroforézy, kapalinové chromatografie na reverzní fázi, gelové chromatografie a MALDI-TOF hmotnostní spektrometrie. Během sladování se vlivem klíčení zrna zvyšuje množství některých proteinů a také jsou tvořeny nové proteiny. V průběhu vaření piva se naopak v důsledku vysoké teploty a enzymatické aktivity proteáz mnoho proteinů rozkládá. Těmto drsným podmínkám odolají jen některé proteiny, které přechází až do piva a mohou ovlivnit jeho kvalitu. Dále byly zkoumány různé odrůdy ječmene a jejich rozdíly. Byly porovnány odrůdy povolené pro výrobu certifikovaného Českého piva s jednou osvědčenou sladovnickou odrůdou a jednou nesladovnickou odrůdou ječmene. Kromě toho byly studovány v alkoholu rozpustné proteiny ječmene a jejich změny v průběhu sladování. Zvláštní pozornost byla věnována vybrané skupině posttranslačních modifikací proteinů: glykosylacím. Neenzymaticky glykosylované proteiny ječmene (neboli glykované proteiny) jsou tvořeny v průběhu sladování kvůli přítomnosti velkého množství glukózy uvolněné z rozkladu škrobu. Glykované proteiny ovlivňují stabilitu proteinů a kvalitu piva, obzvlášť pěnotvorný účinek. Enzymatické N-glykosylace představují nejčastěji studované posttranslační modifikace u rostlin, protože glykoproteiny hrají klíčovou roli v různých biologických funkcích. Glykoproteiny jsou často přítomny v malém množství, a proto je pro jejich analýzu potřebné obohacení glykoproteinů z komplexní směsi. Pro studium glykoproteinů byla využita afinitní chromatografie s lektinem concanavalin A. Kromě toho byla také optimalizována analýza sacharidové části glykoproteinů. Tato disertační práce přináší důležité informace o proteinech ječmene, jejich změnách a analýze, které budou užitečné pro další studium.

Use of renewable energy in the food industry
Čederle, Jakub ; Tuhovčák, Ján (referee) ; Hejčík, Jiří (advisor)
This thesis deals with the use of renewable energy sources (RES) in the food industry, specifically in the brewing sector. The first part of the thesis is devoted to the research of individual RES, while the second part focuses on the description of the brewing industry and the beer production process. In the practical part of the thesis, the energy requirements of the selected microbrewery were analysed, which served as a baseline for the assessment of the possibility to cover its needs with RES. The use of a heat pump, the installation of photovoltaic panels and heat recovery in wort cooling by means of a plate heat exchanger were considered. The work is concluded with an evaluation of the individual solutions.
