Kontrola jakostních parametrů experimentálního masného výrobku za použití vedlejších produktů vzniklých po zpracování vlašských ořechů
Graciasová, Michaela
The diploma thesis deals with the usability of raw materials that arise during the processing of walnuts. The work further summarizes the whole process of technological operations in the production of meat products. The intention of the practical part was to add walnut moldings, which are a by-product of the production of walnut oil. Another batch was made with the addition of whole walnuts. The content of dry matter, fat, protein and salt was determined for the produced Spišské sausages, which was chosen as a suitable model meat product. Subsequently, the color of the Spišské sausage on the section and the surface was determined using a spectrophotometer. The assessment of hygienic quality was based on microbiological analyzes in the form of the total number of microorganisms, fungi, coliform bacteria and enterococci. The main task and goal was the sensory analysis of the products, for which 9 descriptors were evaluated. The sensory analysis shows that in the descriptors the overall (appearance, surface color, hardness and strength of the bite) the Spišské sausage with walnut pomace was evaluated better than the control sample. From the overall acceptability, it is clear that the sample with walnut pomace is less acceptable than the sample with whole walnuts, where the overall acceptability was evaluated much better.

In the theoretical part of my thesis, I firstly analyze five most well known foreign (avocado, soy, goji, chia seeds and quinoa) and Czech (various seeds, poppy seeds, walnuts, blueberries and vegetable juices) superfoods. Then I compare them on four levels- a nutritional, economical, ecological and ethical one. In the practical part I asked several questions related to the problematics of superfoods and with the use of sent out questionnaires investigated whether people know superfoods, what is their opinion on them, if they buy them and whether they think about their origin and deeper problematics of the import of exotic crops. I discovered that more than 75 percent of those questioned are aware of superfoods. Whole 40 percent of people were somewhat sceptical of these foods and only 18,5 percent expressed full trust in them. Almost 73 percent of respondents buy superfoods at least once a week, which reflects their more frequent consumption, while the...
