VOČADLOVÁ, Kateřina
The aim of this work is to assess the public knowledge of heat treatment, its purpose and effect on milk quality and to find out their attitude to raw milk consumption. Heat treatment of milk is a commonly used part of dairy processing. Although the heat treatment has a significant impact on ensuring microbial quality, safety and shelf life of milk, its application still face a public disagreement, primary in connection with potential health benefits, which are lost during heat treatment. The survey took place (from November 2015 to February 2016) in a randomly selected group of respondents (n=265). It was found that 22 % of respondents buy raw (unpasteurized) milk and only 27 % of them reported pasteurizing of the milk before consumption. 68 % of respondents just cool the milk down and consume it without any thermal treatment. 23 % of respondents though that pasteurization has negative effects on milk quality and 21 % of respondents said that consumption of milk pose no health risk.
