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.

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.

Technologie výroby a kontrola jakosti šunek
Poukarová, Anna
This work deals with meat products labeled "ham". Cooked ham belongs to the heat-treated meat products which make up the largest share of this group in the Czech Republic. Quality of the pork ham for hams must be high. It is important to control the correct technological process - the choice of raw material, its processing, salting, tenderizers, massaging, heat treatment and cooling. The content of the pure muscle proteins and their chemical and mechanical activation are very important. Prague ham is the most famous Czech product from this area whose the beginnings of the production falling until to the 60s of the 19th century. Currently Czech association processors of meat require incorporate of Prague ham between traditional Czech specialties. A lot of laboratory methods are used for the quality control of the final product - physicochemical, sensory and instrumental. Sensory evaluation is the oldest and unconditional way of quality control. Instrumental evaluation becomes part of the sensory evaluation in last years. Physicochemical methods provide the most objective evaluation of the results.

Sledování mikrobiologické jakosti paštik
Hábová, Eva
The aim of this thesis was to study the microbiological quality of different types of pâtés supplied by a Czech manufacturer. We investigated the occurrence and changes in selected microorganisms during the storage process. In all cases, we aimed to measure the total plate count, total number of psychrotrophic microorganisms, mold and yeasts and enterococci, as well as Enterobacteriaceae and Escherichia coli bacteria. Part of the samples was also examined for the effects of storage temperature (5 and 8 ° C) on the microbiological quality of pâtés. No statistical significance between microbial quality of the products stored at 5 and at 8 ° C was proved. The worst microbiological quality was discovered in the samples of course pâtés, where high levels of Enterobacteriaceae as well as traces of total plate count, psychrotrophic microorganisms, mold and yeasts were detected. In order to achieve a high microbiological quality of pâtés (as well as other meat products), the use of high quality raw materials and strict compliance with approved manufacturing processes is absolutely essential, as is sufficient hygiene during the production and distribution as well as in the course of the actual sale.
