Microbial contamination packaging glass
 Bělohoubková, Tereza ; Vítová, Eva (referee) ; Veselá, Mária (advisor)
The bachelor thesis contemplates the formation of microbial contamination during production of glass packaging used in food industry. The theoretical part defines the word packaging, its function and legislation of glass packaging. Glass packaging production is described as well as arising risks of potential microbial contamination. Unacceptable microorganisms with ability to live on the surface of glass packaging and possible determination of the microorganisms are characterized in the thesis. In the practical part swabs of produced glass packaging were analyzed by ATP bioluminescence and pH of the inner glass surface was determined to assess species of microorganisms able to live on glass surface. Conclusion of the thesis discusses establishments to lower the risk of microbial contamination.

Application of selected plant materials for the preparation of biodegradable plastics
 TŮMOVÁ, Jana
The main aim of the thesis was to evaluate the feasibility of the production of sustainable and biodegradable films for food packaging made from raw plant materials using casting method. Specific objectives were: a) Optimization of the steps of the casting method for films preparation based on the use of different types of flours, determination of their physical properties (colour, cohesiveness, elasticity). b) Preparation of biobased plastic material from selected types of flours, determi-nation of their physical and mechanical properties (visual and tactile aspects, colour, thickness, moisture content). c) Investigation of the biodegradability of prepared materials based on enzymatic degradation in water suspension and water itself.
