Optimization of packaging properties of selected meat products
ZAJÍCOVÁ, Vladana
The diploma thesis on the topic of optimizing the packaging properties of a selected meat product deals with experimental testing of the properties of plastic casings, specifically designed for Vysočina salami. Polymer NaloFerm clear Dia 55, iCel premium and iCel C* packages were chosen for experimental monitoring compared to the standard NaloFaser phasor casing. The weight of the packaging during the production process, the change in the calibre and length of the product, the course of the decrease in water activity and the final surface appearance of the product were monitored for the packaging samples. Statistically significant differences were found in weight loss among all tested samples (P <0.001). By evaluating changes in parameters during technological operations, data were obtained for manufacturers, where the reason for testing was the targeted selection of new, more suitable packaging for non-fermented meat products.

Substitution of cellulose and non-edible collagen casings by plastic casings in the meat industry in the Czech Republic
BURIAN, Rudolf
The aim of this thesis is to assess the possibility of substitution of cellulose and non-edible collagen casings by plastic casings. The first part deals with selected types of casings, as well as their basic definitions, technological properties and applications, as described in literature. The second part describes the process of carrying out the analysis itself, from the selection of appropriate types of casings produced by Viscofan CZ Ltd. České Budějovice, through the measurement of their chosen technological properties, to the data evaluation

Funktional Effects Improve of Artifical Casings in Meat Production.
BURIAN, Rudolf
The aim of this work is to capture the evolution of functional characteristics of plastic casings used in the meat industry. The first part deals with the history and development of casings as a packaging material and the functional characteristics of plastic casings in general. The second part introduces plastic casings produced by Viscofan Ltd. České Budejovice, focusing on their functional properties, methods for detecting these properties, possibilities of their usage in the meat industry, their processing and influence on extending shelf-life of meat products during storage at low temperatures.
