ABSTRACT:
Methods and compositions are provided comprising ingestibles and a thermochromic composition which is informative as to the temperature history of the ingestible, either prior or contemporaneous with use. Various solid or liquid ingestible compositions are provided for determining storage temperature, temperature of the user, temperature of the ingestible, particularly comestibles, and the like. Of particular interest are polydiacetylene polymers which may be formulated to provide compositions having transition temperature over a broad temperature range.
