    摘要:

    目前,,時間溫度指示器匹配方法多依賴于參數(shù)耦合、相關性分析,、實際物流過程的調(diào)試驗證等方法,,鮮有從匹配機理出發(fā),在反應進度上剖析時間溫度指示器的匹配要求和規(guī)律,。本文在多級反應動力學模型的基礎上,,以保持時間溫度指示器與待測農(nóng)產(chǎn)品的反應進度一致性作為目標,建立了時間溫度指示器匹配的理論和方法,,并通過理論推導和實證模型驗證了時間溫度指示器與待測農(nóng)產(chǎn)品之間匹配的條件,。當指示器與待測農(nóng)產(chǎn)品服從任意多級反應動力學模型的匹配條件(二者在任意合理的恒溫條件下的有效反應時間相等或二者等量線重合)時,即可使用該指示器預測對應農(nóng)產(chǎn)品的品質(zhì)變化和貨架期,,此時二者的反應速率函數(shù)存在一定比例關系,。借助該方法推導出可以精準指示科瑞森無核葡萄硬度的不同級反應動力學方程,證明了該方法的可行性,。

    Abstract:

    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.
