Sixteen qualitative focus groups and a quantitative survey were conducted in four European countries (Finland, Greece, France and Germany) in 2012 to capture consumers' views on both time–temperature indicator (TTI) technology concept and two commercial TTI applications. The results of the study show that consumers in all countries understand the value of the TTI concept, but the studied applications did not meet the consumers' expectations implying the need for further work to enable the TTI acceptance among consumers.
