Mechanically separated meat from poultry produced by different techniques: Proteins, fat and bone fragment determination.
Čížková, Silvie ; Babák, Libor (referee) ; Šalplachta, Jan (advisor)
The diploma thesis is focused on mechanically separated chicken meat (MSM), which was produced on the machine Baader 601 (soft way of separation) and Lima D (hard way of separation). The history, production, composition and legislation relating to the MSM have been described in the theoretical part. The experiments involving the results of the determination of total solids, total fat, total protein, muscle protein and collagen have been introduced in the experimental part. Bone fragments have been determined by weight and visually after alkaline hydrolysis of samples at elevated, respectively atmospheric pressure. Results have been evaluated with regard to the feedstock and the method of mechanical separation. Values have been compared with data published in the scientific literature and legislative requirements. Data from the experiment confirm high variability and thus different food quality of MSMs, depending on the sort of feedstock used in the production of MSM and the separation method.

Quality of poultry meat in relation to the production method
KADLECOVÁ, Lucie
The topic of this thesis is the quality of poultry meat in relation to the production method. In the literature review, poultry meat is described, then its consumption in the Czech Republic and its chemical composition. Selected methods of sensory analysis are also described. Types of tested meats are characterized in the practical part. This thesis is also focused on the experimental evaluation of the chemical composition of chicken breast muscle from the Loužná farm using the NIR method and comparing the composition changes depending on the age of the chickens. It is followed by selected sensory methods aimed at recognizing differences in chicken meat from three different productions. In addition, there was published a questionnaire to determine citizen's preferences for products (chicken meat) from different production methods.

Quality of poultry meat in related with production method
KADLECOVÁ, Lucie
The bachelor thesis is focused on the analysis of the basic components of breast cutting from free-range and conventional breeding of chicken. The samples of free-range meat came from Loužná farm; the conventional samples came from poultry farm in Klatovy. The main aim of the thesis was to determine the water, fat, protein and collagen content in meat using NIR methods. The literature review explains differences between the ways of breeding, various effects on the quality of meat and meat defects. In next chapters, the results of the measurement compared to findings from the literature and food standards are presented. The conclusion contains a summary of all facts.
