Uplatnění mouky z hlíz topinamburu ve výrobě výrobků z mletého masa / Use of meal from Jerusalem artichoke tubers in production of products from minced meatMUŽÍKOVÁ, Monika January 2017 (has links)
Jerusalem artichoke is a root vegetable containing glucofructan inulin in its tubers that is valued for its positive effect on the human organism. The aim of thesis was to evaluate use of meal made from Jerusalem artichoke tubers in production of products from minced meat. The experiment was divided into two parts. In the first part, the differences in water-holding capacity of semi-rough wheat flour and Jerusalem artichoke powder (JAP) in various types of solvents were determined. The statistically significant difference in water-holding capacity between the flours was found solely in the saline solution. Furthermore, the results showed that type of solvent had the main effect on water-holding capacity. In the second part of the experiment, 4 types of meat products were made - sausages, meatloaf, liver pate and meat hash. Wheat flour, which is commonly added to these products, has been completely replaced by (JAP). Subsequently, the sensory analysis was evaluated by experts (n = 16) for an estimation sensory quality and sensory changes of new product with JAP compared to standard meat products. The results of the study showed that the addition JAP to sausages had a negative effect on its sensory quality, namely its overall appearance of the product, texture and taste. On the contrary, there were improved functional properties in meatloaf (juiciness) and pate (taste). According to the results of the sequence test, the liver pate was found the most delicious product.

Senzorické hodnocení trvanlivého masného výrobku v závislosti na technologii výroby. / Sensoric assessment of the durable meat product depending on the production technology.TÁBOR, Rudolf January 2011 (has links)
This diploma thesis deals with sensoric analysis of the selected types of durable meat products depending on the production technology. By sensoric assessment and subsequent statistic analysis, this diploma thesis pursues to compare fermented durable meat products, made without added starting cultures, with fermented durable meat products, made with added starting cultures, and to determine which of these kinds of products are preferred by the evaluators as well as the consumers. The theoretical part of this thesis summarises the conclusions arising from the sensoric analysis of the food, including its conditions and statistical evaluation, sense perception generally and the technology of the production of fermented durable meat products. In the practical part, the applied method and results of the performed twin preference test are described. Samples of the durable meat products of the major domestic producer of the durable meat products, commonly distributed and accessible in the trade network of the Czech Republic, were used for the purpose of evaluation.

Přídatné látky ve vybraných masných výrobcích v ČR / Food additives in selected meat products in the Czech RepublicVondrášek, Pavel January 2016 (has links)
Univerzita Karlova v Praze Pedagogická fakulta Katedra pedagogiky DIPLOMOVÁ PRÁCE Přídatné látky ve vybraných masných výrobcích v ČR Food additives in selected meat products of the Czech Republic Pavel Vondrášek Vedoucí práce: Ing. Bc. Alena Váchová, Ph.D. Studijní program: Učitelství pro střední školy Studijní obor: Učitelství všeobecně vzdělávacích předmětů pro základní školy a střední školy pedagogika - výchova ke zdraví 2016 1 ABSTRACT The issue of food additives is a very hot topic in the current society. This fact has been recently reflected in a fair amount of legal regulations governing this industrial branch and almost hysterical campaigns of various food-providing chains that are trying persuade the public that only and just their products are free of any such additives. At the same time, however, and quite effortlessly can each of us get quite opposite information that would definitely harm the aura of safety created round the food additives. It is evident that a typical man takes mostly subjective attitude in this chaos of opposing information which is supported by different fabulations or "reliable information". The aim of this thesis is to clarify the issue of food additives and their use in meat-based products that form one part of unhealthy eating habits in our society. The acquired...

Senzorické hodnocení různých typů masných výrobků / Sensory evaluation of different types of meat productsLanžhotská, Aneta January 2020 (has links)
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.

Drůbeží masné výrobky, technologie výroby, trh / Poultry meat products, technology of production, marketKOLÁŘ, Petr January 2013 (has links)
This thesis is focused on poultry meat and its products. A definition of meat, sources of meat, types of poultry production and own goal of the thesis are explained in the first chapter. Then there are described technological processes of poultry treatment in common with a veterinary and hygienic supervision which provides a check of the production and processing of poultry meat. In addition, there are mentioned some manufacturing companies which are engaged in poultry processing. The third and the fourth chapters are about a general characteristic and a quality of poultry meat. There are described issues related with poultry meat and its quality, structure, production and consumption in the following chapter. The last chapter is theoretical and there is taking apart the main problem of this thesis which means the production of poultry meat products, other poultry products and an overview of legislation related to poultry meat products. The practical part is focused on consumer attitude to poultry meat and poultry meat products and other kinds of meat by a questionnaire. A discussion and evaluation are based on resulting graphs. An appropriate conclusion was developed from this part of thesis.
