a chemical reaction to track, mimic and indicate the deteriorative processes (like microbial growth) in perishables. Zhang said.
The kinetics of both microbial growth and chemical reactions are temperature sensitive, so if we could somehow manage to make them parallel to each other, then you could tell the quality of the perishables by checking how far the chemical reaction has proceed, he added.
And some information about this particular chemical reaction we used for the tag, namely silver
