Analysis of selected milk quality indicators and their impact on the yield and sensory properties of fresh cheeses
 PLONER, Michaela
The aim of the diploma thesis was to evaluate the effect of cow´s milk quality on the fermentation, yield and selected properties of fresh cheese produced in laboratory conditions. For this purpose, there were 51 fresh cheese samples produced in three trials from 17 bulk milk samples originating from six farms. For milk and cheese sam-ples, selected analyzes were performed, and the obtained data were statistically eval-uated. The chemical composition, physicochemical and sensory properties, weight and yield of fresh cheese were evaluated depending on i) the time of fermentation, ii) the milk quality. As expected, the average values of pH, weight and yield of the fresh cheeses differed during the fermentation. The protein content, lactose and so-matic cell counts significantly influenced the yield and quality indicators of fresh cheese. The quality of milk also influenced the assessment of sensory properties, es-pecially color intensity and consistency. To achieve the optimal pH of fresh cheese (<5.00), the time of fermentation should be from 15 to 16 hours.

Children's eating habits
 PLONER, Michaela
This bachelor thesis deals with children´s eating habits. My thesis is focused on eating habits of preschool children. It comprises two parts. First part deals with children who do attend nursery school and second part deals with children who do not attend nursery school. Theoretical part of this thesis is focused on how the healthy eating habits should look like and what should be the average daily amount of nutrient intake. Thesis deals with factors associated with nutrition and developing eating habits. It also deals with the way children eat in nursery school. I interviewed 60 preschool children and their parents. 45 of these children attend nursery school and 15 do not. This thesis comprises two parts. The aim of first part was to evaluate what are current children´s eating habits. The aim of second part was to analyse the amount of nutrient intake. Practical part of my bachelor thesis is based on a questionnaire. 28 questions were answered by parents. I monitored both groups and their five-day dietary intake of morning snack, lunch and afternoon snack which should contain about 60 % of daily dietary intake. Collected data were analysed using programme Nutriservis Professional. I get the average dietary intake value and the amount of nutrient. As far as my research shows, the average dietary intake value more or less correspondes with recommended preschool children´s dietary intake. Eating habits are a little bit different but could be evaluated as acceptable. The worst factor is the frequency of particular food groups consumption. Unfortunately, it does not correspond to recommended amount of daily intake. The difference between children who eat in a nursery school and children who eat at home is imperceptible.
