Different temperature conditions can cause food loss and waste and the
United Nations are pushing towards the reduction of food waste. One of
the greatest problems in the food trade is the effective management of the
cold chain, as short-living foodstuffs have to be maintained below 5°C. If the
temperature levels are not below 5°C along cold chains food can be spoiled
and this in turn can lead to food poisoning. Better temperature control along cold chain can make food safer, but the most effective management
of the cold chain can be achieved through establishing control systems, such
as intelligent packaging. Such forms include Time Temperature Indicators
(TTIs) and the most common type is biological, polymerised, diffusionbased,
electrochemical and photochemical. TTIs can have a straightforward
application in the industry as scientists developed a model to be massively
produced.
