Sensory evaluation of different types of meat products
Lanžhotská, Aneta ; Vespalcová, Milena (referee) ; Diviš, Pavel (advisor)
The diploma thesis deals with sensory evaluation of selected types of meat products, specifically sausages. Different types of sausages, which contained added chemicals and spices, were compared. The theoretical part describes the properties of meat and meat products and the basic technological procedures used for their processing and production. Furthermore, added substances and spices, which are often considered as flavorings or preservatives, were characterized. The principles of correct performance of sensory analysis and sensory perception of food were also presented, which include a description of the sensory workplace, sample preparation, its implementation, procedure and various evaluation methods used. The experimental part describes the specific work tools used and the conditions under which the evaluation took place. A total of 12 types of sausages were evaluated, 7 of which came from meat production and 5 were prepared in the laboratory of food chemistry at Brno University of Technology. The differences between the samples of sausages, which differed in content and type of added chemicals and spices, were clearly shown using ray graphs. Then the Grubbs test was used, which excluded outliers from the final evaluation. These values were further excluded from further evaluation. The Kruskall-Wallis test was used to distribute the resulting mean values and to determine whether there was a statistically significant difference in sensory evaluation between the results. An appendix to the Kruskall-Wallis test Dunn's test was used to divide the resulting values into given groups according to statistically significant difference and similarity. The analysis of the main components of the so-called PCA was used to find the differences and similarities of the samples included in the groups.

The Death Pit and the Glowing Swamp: A Permeation
Smutný, Jan ; Marek, Petr (referee) ; Cenek, Filip (advisor)
The work is connecting well-known symbols of alchemy and various esoteric traditions and giving them visual and narrative form. There is deconstruction and glorification of this type of philosophy in the same time. The characters of the story are symbolizing the german and slavic archetypes. Their voyage from the pit of death to the glowing swamp and vice versa is representing the ageless story of life and death, creation and destruction, body and soul, light and darkness. All the symbols are used in the ironic and serious way in the same time.

Characteristic of nutrition values of meat from different animals
Kubištová, Petra ; Zlámalová Gargošová, Helena (referee) ; Omelková, Jiřina (advisor)
ABSTRACT In this thesis, there were assessed basic nutrition values of meat from different animals. Beef meat (bulls, heifers and veal), pork meat ( castrates, boars and gilts ), rabbit meat and chicken meat were included in the experimental part. There were moisture, lipids, proteins, ash and hydroxyproline determinated. Attention was given especially to the content of lipids and moisture. The animals were compared in terms of their type and on the basis of possible differences between sex (beef and pork meat), breed (beef and rabbit meat) or between different parts of animals` body (chicken and rabbit meat). Individual types were also compared with each other. For human nutrition it is possible to recommend veal meat, which contained the least amount of fat, MLD from rabbit meat and chicken breasts. Pork meat from young animals is comparable to chicken breast as regards the content of fat. We should also not omit beef meat in our bill of fare. Thanks to breeder technology the beef is now lower in fat than it used to be and contains valuable matters of red meat.

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.

Aktuálna problematika zrenia mäsa vo vzťahu k očakávaniam a požiadavkám zo strany spotrebiteľa
Gago, Branislav
This work investigates the effect of aging on meat quality. The research is based on a review of current scientific literature, including studies on biochemical and sensory changes that occur during aging. In particular, i compared the effects of aging on marbling, tenderness, flavor and moisture content. Further, the effects of different aging processes such as dry aging and wet aging were discussed. In addition, the economic and health benefits of aged beef were also investigated. The results showed that aging can have a positive effect on the quality and flavor of the meat, leading to increased tenderness and marbling, as well as improved flavor and juiciness. Additionally, dry aging has been found to be more effective in increasing beef quality compared to wet aging. Finally, the economic and health benefits of ripening were emphasized.

Použití koření v masné výrobě
Pelikánová, Natálie
The bachelor thesis deals with the principles of meat production and the related use of spices in meat production. All production processes are based on legislative regulations issued by the State or the European Parliament and the Council. Furthermore, the meat industry cannot do without meeting HACCP requirements. This system deals with critical control points in production and these are further controlled by state bodies such as the State Veterinary Administration or the State Agricultural and Food Inspection Authority. Currently, there are many types of meat products, which are divided into several groups according to Decree 69/2016 Coll. Similarly, there are many ways of processing meat. These include not only heat treatment but also fermentation or smoking. In meat production, we also encounter the use of additives in various concentrations, but also various substitutes for spices or meat itself.

Kvalitativní parametry a využití masa nutrie říční
Neudertová, Karolína
The aim of the bachelor thesis Quality parameters and uses of nutria meat was to conduct a literature search focusing on the use of nutria meat in the Czech Republic and in the world. Nutria breeding has a long tradition in the Czech Republic. Previously, breeding was primarily focused on the production of quality fur, with meat and fat as by products. Nutria meat is often sought after in developing countries such as Africa or Asia, where nutria meat increases food self-sufficiency. Among European countries, nutria meat and products have a market presence in France. Nutria carcasses do not contain the head, skin, genital organs, bladder, gastrointestinal tract, distal parts of the legs, thoracic organs, liver, kidneys and peritoneal fat. The protein content of nutria meat ranges from 19.2 to 25.5 % and the fat content ranges from 4 to 10 %. Nutria meat has a higher collagen content than rabbit meat, making it more tender and more sought after by consumers. The meat is characterised as tender because of its higher peritoneal fat content. Nutria meat has a low intensity of aroma and flavour, so appropriate culinary preparation is important. In terms of technological parameters, nutria meat has a higher pH value and a darker colour.
