Summary 

Shelf-life of products, their safety and quality is strictly dependent on storage time and temperature especially when fresh and minimally-processed food is concerned. The paper presents issues concerning food products deterioration due to temperature abuse in the distribution chain and possibilities of monitoring them using time-temperature indicators (TTIs). It focuses mainly on fresh or minimally-processed chilled and frozen food products and different TTIs for monitoring their shelf-life. It also gives commercial examples of TTIs applications and mentions legal regulation regarding active packaging. The paper also shows the studies on the 3M Monitor MarkTM  responses/colour changes under different temperature conditions and on different packaging materials (cardboard, polystyrene trays).
