Abstract

PURPOSE: To establish the simple temperature sensing tool for frozen food, by sealing the specific first and second substances showing color with mutual contact in the microcapsule which causes cracks less than a specific temperature and commonly using the both.
CONSTITUTION: Water solution (first substance) 1 in which table salt and propyleneglychol are added to the reagents such as acid and alkali and the freezing temperature is adjusted to a given temperature (e.g. -18°C), is sealed in the microcoupsel 2 about several to several hundreds of μ in diameter adjusted so that cracks are caused at the said temperature. On the other hand, the water solution (second substance) 3 of the indication reagent showing color with the reaction with the said first substance (e.g. methylred, phenolphthalein) is sealed in the same microcapsule 4, and the said both are used with attaching on the enclosure paper 6 of the frozen food 5 with adhesives 7.
