Possibilities of using moringa oleifera in the production of meat products
Richterová, Nikola ; Slavíková, Zuzana (referee) ; Mikulíková, Renata (advisor)
This bachelor thesis deals with the addition of moringa oleifera and its influence on the sensory quality of meat products, specifically wine sausages. The theoretical part describes the meat, the division of meat products, and the basic technological operations leading to their production. Furthermore, wine sausage, its composition, and production technology are characterized. The description of moringa oleifera and its chemical composition follows. The conclusion of the theoretical part is devoted to sensory analysis, conditions for sensory assessment, and the main methods of this analysis. The experimental part is focused on the production of wine sausages with various additions of moringa oleifera and subsequent sensory evaluation of these sausages. When assessing the sensory quality of the sausages, the samples were evaluated according to their appearance, smell, taste, and texture. A total of 25 evaluators, who were representing ordinary consumers, took part in the sensory evaluation. The content of lipids and fatty acids in the samples of sausages was analyzed by gas chromatography. A separate sample of Moringa was also analyzed by gas chromatography. The polyphenol content of the samples was determined by liquid chromatography. Using the Kruskal-Wallis test, it was found that there were statistically significant differences between the samples. The sample with the lowest addition of moringa and the sample without moringa were assessed very similarly and were evaluated as the best. While the sample with the highest moringa addition was rated the worst in all assessed categories.

Netradiční druhy masa a jejich využití pro potravinářské účely
Veselá, Romana
This thesis deals with non-traditional meats and their use for food purposes. Specifically, there are 5 species, namely crocodile, ostrich, buffalo, llama and capybara. These meats are suitable as an alternative to commonly consumed meats, but also as a dietary diversification. In some cases, they are healthier, more nutritious, more dietetically appropriate and more appealing in terms of taste. Their disadvantage is their low availability and often high price. In the food industry, they are used in the same way as commercially available meats for the production of canned meat, sausages, semi-finished products, smoked meat products, dried meat and also directly in restaurants for steaks.

Perspektivy a problematika masné výroby v rámci regionální produkce
Suchánková, Žaneta
The subject of this bachelor thesis is regional meat producers. The first part of the literature search deals with the quality regimes of the European Union and the Czech Republic. Both positive and negative aspects of the labelling systems in their impact on producers, consumers and the environment are presented. The environment is the main reason for the introduction of this sustainability strategy. The link to a particular place is also important, as is the tradition that consumers associate with higher quality products. The second part of the thesis thus focuses on the production of pâté according to the Czech Guild Standard, which refers to traditional and honest processing technology. The technological process is related to economic, hygienic and sensory quality.

Zvěřina jako surovina pro výrobu masných výrobků
Greplová, Jana
The topic of the bachelor thesis is Venison as a raw material for production of the meat products. The thesis defines the terms meat, the game and the venison. It describes the classification of the game, the ways of the hunting and its influence on the venison’s quality and hygiene. The thesis compares the biological and physical risks that may be dangerous for the final consumer. There are a diagram of meat production and possible final products from the venison meat. The separate chapter is devoted to the religion influence is dealt with in a separate chapter, this chapter describes the special requirements for the killing animals and their subsequent consumption in other cultures.

Kontrola jakostních parametrů experimentálního masného výrobku za použití vedlejších produktů vzniklých po zpracování vlašských ořechů
Graciasová, Michaela
The diploma thesis deals with the usability of raw materials that arise during the processing of walnuts. The work further summarizes the whole process of technological operations in the production of meat products. The intention of the practical part was to add walnut moldings, which are a by-product of the production of walnut oil. Another batch was made with the addition of whole walnuts. The content of dry matter, fat, protein and salt was determined for the produced Spišské sausages, which was chosen as a suitable model meat product. Subsequently, the color of the Spišské sausage on the section and the surface was determined using a spectrophotometer. The assessment of hygienic quality was based on microbiological analyzes in the form of the total number of microorganisms, fungi, coliform bacteria and enterococci. The main task and goal was the sensory analysis of the products, for which 9 descriptors were evaluated. The sensory analysis shows that in the descriptors the overall (appearance, surface color, hardness and strength of the bite) the Spišské sausage with walnut pomace was evaluated better than the control sample. From the overall acceptability, it is clear that the sample with walnut pomace is less acceptable than the sample with whole walnuts, where the overall acceptability was evaluated much better.

The content of basic analytical constituents in selected meat products
KŘIVÁKOVÁ, Tereza
The aim of this study was to assess selected analytical values (water content, fat, protein, collagen and salt parts) in chosen meat products ( at least 50 pieces of product) using NIR methods. There were chosen five kinds of meat product as a studying material ham sausage ("špekáček"), sausage ("vídeňský párek"), salami ("gothajský salám"), salami ("vysočina"), bacon ("anglická slanina") from ten different manufacturers from the Czech Republic. The results showed that "vysočina" was the most fatty and salty, with a maximum content of collagen and the smallest water content. "Vídeňský párek" contained the most water, but positively it was the least fatty and salty. "Gothajský salám" was evaluated as the lowest one within the quality because the results confirmed the lowest average of protein content. The smallest content of collagen was detected by "anglická slanina" and at the same time there was the maximum variability in water content, fat content , protein and collagen as well. The most negatively correlated water and fat.There exists extremely high dependence with "anglická slanina", "gothajský salám","špekáček" and this relation is presented as very high in statistical significance (p0,001). Similar results and statistical significance (p0,001) were detected between fat and protein with "anglická slanina".

Kupka, Jan ; Kořánová, Helena (advisor) ; Hůlová, Marie (referee)
This bachelor thesis focuses on the issues of quality meat products on the czech market. The aim is to determine the selected preferences of consumers when buying sausages with a focus on the consumption of "spekacek". Further clarification of the marginal effect of chain stores on the quality of sausages. An essential part of the thesis is to define the legislative requirements and theoretical grounds. To meet its declared objectives, I conducted a survey among consumers, which was based on personal interviews. Subsequent analysis of information obtained from the answers of the respondents brought the findings of selected consumer preferences.
