The effect of selected demographic factors on sensory evaluation and acceptability of commercial milks
 TOMÁŠKOVÁ, Denisa
The diploma thesis was focused on a sensory evaluation of selected types of milk (pasteurized and UHT; both as 3.5% and 1.5% of fat content) and their acceptability depending on demographic factors. The next aim was to evaluate a questionnaire survey concerning this commodity. For sensory evaluation, the method of a paired preference test for a pasteurized milk and UHT milk of the same fat content was used. Furthermore, a ranking method for all samples was used. All the participants of the survey were university students. A total of 61 evaluators (average age 24.4 ? 6.7) participated in the sensory analysis and 106 respondents (35 ? 16.9) in the questionnaire survey. Research of the sensory evaluation revealed that evaluators preferred UHT milk and that they liked milks higher in fat more. Questionnaire survey showed that the taste of milk was the most important criterion for decision, followed by quality and the content of fat. Advertisement played the smallest part in a milk selection.
