Abstract:Through the time-temperature indicator CARDS (TTI) mechanical, chemical and electrochemical, enzymology or biology irreversible changes, to indicate the food the temperature change of the process and the remaining shelves information, so as to control food sales. Time-temperature indicator CARDS according to its principle different can be instructed to each category food. This article is for fish, meat and frozen foods, the main indicator of fish, meat and frozen food temperature history and the remaining shelf. Four programs designed according to different characteristics of different foods to indicate the fish, meat and frozen food temperature history and the remaining shelf life information.
