Problematika výroby piva technikou vysoce koncentrovaných mladin ve vztahu k Českému pivu
Němeček, Radoslav
The aim of my bachelor's composition was to determine the suitability of beer production by technology of highly concentrated wort for the production of Czech beer. In bachelor's composition is described the beer production by this method, hereafter is the issue of Czech beer production and its parameters. To evaluate the suitability of this method of production was breewed experimental tribal brew of beer, which was used in the subsequent production of the finished beer. The beer was evaluated by sensory page. From the results of my research implies that the method highly concentrated worts can be used for the Czech beer production. It should not happen to great misuse for rapid cost reduction.

The influence of origin in intensively bred European perch (\kur{Perca fluviatilis}) on mass yield, chemical composition and organoleptic properties of its meat
FLOKOVIČ, Ondřej
A breeding of seven European perch (Perca fluviatilis) groups of various origin was carried out under experimental conditions at 20°C temperature since the hatching of larval fish up till the age of 278 days, with intensive feeding using BioMar Inicio plus 0,55mm fodder with 15% fat content and BioMar Inicio plus 0,1mm fodder with 18% of fat content in later initial feeding. The average final weight of fish in the individual groups ranged between 79,4g and 27,63g. Mass yield statement (mass fraction of skinless filets, on the total mass), basic chemical analysis of filets (dry matter, crude protein, lipids and ash content) and organoleptic evaluation of musculature quality were carried out in the final stage of the growth test. No influence of the fish origin on the mass yield was detected. The average values ranged between 35,41% and 32,21%, but an influence of origin on crude protein content was discovered. The lowest values were determined in the population from the north of Germany 77,5% and the highest values on the contrary were determined in the population from the Štrbské Pleso lake 80,35%. The lowest lipids content was determined again in the population from the north of Germany 7,14%, while the highest fat content was detected in the population from Slovakia 8,66%. The results of organoleptic analysis didn't show substantial differences. Overall it can be stated that the monitoring didn't prove any substantial influences of fish origin on the parameters observed, which is confirmed by results of similar observations carried out by other authors e.g. with trout and carp.

Responsible Effects for Sensory Character of Meat Products
BAŽANTOVÁ, Eva
The thesis is literature review on the subject - Responsible Effects for Sensory Character of Meat Products. The introductory part deals with the human sense. Visual sense, smell and taste are of great importance in the sensory evaluation of foods. For meat and meat products to evaluate the sensory characteristic - color, aroma, flavor, consistence, succulence, texture, general appearance and appearance on cut. Various meat products differ in the way of production. According to current legislation are divided into seven groups. Sensory properties are affected by the quality of input materials, recipies, additives, packaging and process technology. Good manufacturing practices ensure the sensory quality of products.

Organoleptic qualities of catering provided to students in students´cafeteria of the South Bohemian University ,Ceske Budejovice as compared with the catering delivered to clients of the South Bohemian Hospital ,Ceske Budejovice, a.s.
RYTÍŘOVÁ, Zuzana
The thesis, as the title suggests, deals with the quality and organoleptic characteristics of meals prepared in the Students´ canteen of the University of South Bohemia. In the theoretical part the basic principles and composition of a quality and healthy diet are described with the use of literature, the history and basic information about clinical dietology is mentioned and the importance of organoleptic characteristics is explained. The issue of catering facilities and canteens is also addressed. There is an emphasis on the quality of the diet because this is an integral part of a patient´s treatment and ought to be chosen carefully. In the practical section the results of quantitative survey conducted with the České Budějovice hospital clients and the University of South Bohemia students are shown. This investigation aims to highlight the good quality and the drawbacks of their diet and determine the level of satisfaction both in patients of České Budějovice Hospital and students of the South Bohemian University. Before starting the investigation three hypotheses were stated. Based on data evaluation only the hypothesis number one and the second part of the hypothesis three proved true. The Hypothesis number two and the first part of the hypotheses number three were not confirmed.
