ABSTRACT:
The thaw indicator is formed from a frangible capsule made of edible wax. A mixture of edible gelatin and colored water is sealed inside the capsule. The wax capsule is surrounded by a non-toxic blotter-like absorbant material which is coextensive with and in contact with the outer surface of the capsule. A time-delay for the thaw indicator is provided by adjusting the concentration of the gelatin and water mixture.
