The matching method for time temperature indicator (TTI) is the critical factor affecting the application of intelligent indicator. Most current methods depend mainly on the corresponding parameters coupling, correlation analysis and practice logistics verifying without concerning about the reaction extent in matching mechanisms between TTI and agriproduce which needs to be monitored. The relationship between remain shelf life and reaction extent was established and a new matching method between TTI and agriproduce was constructed through keeping the consistency of their reaction extents based on the norder kinetic models. After a series of analysis and formula, the condition for matching between them was the valid reaction time or remain shelf life of them under any reasonable isothermal process were equal, or the contour lines of them were coincident, no matter whether the orders of their kinetic models were equal or not. In this case, there was a proportional relationship between the reaction speeds of them which was a key character under matching condition. By using the result above, three kinetic models with different orders were constructed, and the matching method was verified based on the consistency of their reaction extents, the appreciate kinetic functions of TTIs for indicating the firmness quality of Crimson seedless grape precisely under alternative and constant temperature logistic was deduced in different order kinetic models. The conclusions validated the feasibility and effectiveness of the proposed method, which could promote the application of TTIs.
