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.

Maso a maso nahrazující suroviny pro masnou výrobu
Konvalinová, Žaneta
This bachelor thesis is dealing with meat and substitutes in meat products. First and second chapter are dedicated to definition of meat and meat products, its standards, where the priory is safety of food. The third chapter is dedicated to substitutes of vegetable and animal origin, which are used mainly from an economic prespective. From vegetable substitutes dominate starch, roughage, soybean protein and cereal protein. And from animal protein are milk proteins, egg, blood, collagen and unpopular mechanically separated meat. Mainly poutrly mechanically separated meat, which can be found in many poultry products. In last chapters are introduced products which according to legislation are allowed to contain certain substitutes (milled products) or are not allowed to contain any substitutes (ham of the highest quality and ham of the selective quality).
