My diploma thesis deals with spreadable meat products. Theoretical part is based on information about basic raw materials, production and packing materials of liver sausages, liverworts, spreadable ferment sausages and especially liver pâté. In my diploma thesis is described hygiene and safety in sphere of food industry and more and more discussed quality of products as well. Practical part is divided into five items and discovers four kinds of liver pâté varying in structure and wrap. First one occupies with samples according to given descriptions followed by colour evaluation, instrumental method and microbiological determination of growing CPM during storage.In addition there is a guestionnaire of popularity and frequency of consumption of spreadable meat products.

In this work is analyzed the impact of different varieties on the quality of the tubers. Dif-ferent methods are used to evaluate the quality of potatoes. The objective of this thesis was to assess the quality of fifteen different varieties: Adela, Arlet, Dali, Impala, Jolana, Keřkovské rohlíčky, Lada, Magda, Marcela, Margaret, Mirage, Monika, Primarosa, Raphael, Rosara. Fol-lowing parameters were evaluated: starch content, the skin color and tubers and table value. Measurements were performed in the laboratories of the Mendel University on the Institute of food technology. When determining the starch content, the lowest amount has been found in a variety Adele, while the highest in a variety Magda. Regarding skin color measurement, the lightest was variety Rosara and the darkest variety Monika. The detectable difference in raw and cooked tubers was found when determining the color of tubers. Based on the sensory analysis varieties were classified into 3 groups according to boiling type. Boiling type AB was evaluated in the varieties: Rafaela and Rosara. The boiling types BA included varieties: Dali, Keřkovské rolls and Primarosa. Most varieties showed parameters of the boiling type B: Impa-la, Margaret, Monika, Lada, Marcela, Mirage, Adela, Arlet, Jolana.

The diploma thesis is focused on meat products and the contents of salt in these. The theoretical part contains definitions and classification of meat products followed by a general description of the principles and methods used in the production of meat products, including the particular phases of their processing and the evaluation of their quality. Another part is dedicated to the specific characteristics of the Debrecen sausages, the ingredients used, and the production process. Moreover, the thesis deals with the basic facts about salt as well as with the disputed issues regarding the excessive consumption of salt, its consequences on people's health, and the possibilities of its reduction. The practical part of the thesis contains the evaluation of the quality criteria differences between the Debrecen sausages with the reduced amount of salt and those with the usual composition. The evaluation is based on chemical and microbiological analysis followed by the instrumental measuring of colour and sensory evaluation of samples.

The diploma thesis Microbial contamination of honeys in the literature recherche presenting chemical composition of honey, its properties and effects to human health. The major part deal with microbial contamination of honey, characterization of important groups of microorganisms and describing defects of honey produced their activities. Further it shows with possible ways of precaution against these undesirable changes. The experimental part is focused on microbiological analysis and spectrophotometric measurement of floral and honeydew color, purchased directly from beekeepers from the region Vysočina. Investigating changes in numbers of microorganisms and changes color over time.

The theme od this dissertation is " Application of Spectrophotometric methods for inspection adulteration of food". In the theoretical part, there are stated chapters regarding adulteration of food (in general), adulteration of honey, quality requirements on honey, spectroscopy and its categories. The dissertaion is focused on spectrophotometric measurements of honey and sugar syrup samples where colour and consistence of honey was monitored. The techniques used for the analysis are NIR spectrophotometry and UV/VIS spectrophotometry. The results gained were statistically and graphically processed. It follows from the outcome that using FT-NIR for adulteration of honey detection is an appropriate method for honey inspection. The least effective method for proving adulteration of honey is the spectrophotometry specification of the colour of honey. Using this method, it is not possible to prove the links between colour of honey and colour of sugar syrup.
