Research on Time-Temperature-Integrators of Meal-Ready-to-Eat Military Food Made by Thermo-sensitive Dyeing

摘要

The quality of meal-ready-to-eat (MRE) military food was indicated. [Method] Based dyestuff 2-phenyl-3-methyl-6, 6-2 D-amino fluorane and 2, 2-bis (4-hydroxyphenyl) propane color developer thermo-sensitive system, time-temperature integrators (TTI) produced black by thermo-printer and faded gradually to show quality change of MRE military food. The timetemperature-optical density relational model of the TTI was compare with the time-temperatureacid value dynamics model of the food. it can match the time-temperature-optical density model of TTI to the time-temperature-acid value dynamics model of meal-ready-to-eat military food. The active energy of TTI's reaction is 74.1 kJ/mol similar with 77.7 kJ/mol of MRE military food's reaction. The optical density of TTI's standard camera is 0.8 compared with shelf life of MRE military food.
