Abstract

Method for detecting and signalling the defrosting, even temporary of frozen prods. uses a detecting device consisting of a closed container contg. two distinct elements which are kept separate at low temps., but at higher temps. are caused to come together and interact in an irreversible manner. Pref. the two elements are a colourless and a coloured element which are kept separate under frozen conditions but form a single coloured mixt. on defrosting. They may be a liq. and a dye sepd. by a frangible wall or capsule or diaphragm; or a liq. and an absorbent; or two solids which diffuse into each other on thawing.
