ShareTime-temperature indicator materials given green light by EFSA
The European Food Safety Authority (EFSA) validates active materials used to create time-temperature indicators on chilled food packaging.
Active materials used to create a time-temperature indicator on chilled food packaging have been backed by the European Food Safety Authority (EFSA).
The intelligent system is based on a non-pathogenic micro-organism, C. maltaromaticum, which is used together with a colour change indicator, acid fuchsin, and a gel made of a nutritive medium.
Depending on the time-temperature profile experienced by the system, C. maltaromaticum grows using the carbon source of the medium and releases substances that cause a pH change resulting in colour modification from green to red. This indication is then used to monitor whether the cold chain has been broken.
