    摘要:

    目前,時(shí)間溫度指示器匹配方法多依賴于參數(shù)耦合,、相關(guān)性分析,、實(shí)際物流過程的調(diào)試驗(yàn)證等方法,鮮有從匹配機(jī)理出發(fā),在反應(yīng)進(jìn)度上剖析時(shí)間溫度指示器的匹配要求和規(guī)律,。本文在多級(jí)反應(yīng)動(dòng)力學(xué)模型的基礎(chǔ)上,以保持時(shí)間溫度指示器與待測(cè)農(nóng)產(chǎn)品的反應(yīng)進(jìn)度一致性作為目標(biāo),,建立了時(shí)間溫度指示器匹配的理論和方法,,并通過理論推導(dǎo)和實(shí)證模型驗(yàn)證了時(shí)間溫度指示器與待測(cè)農(nóng)產(chǎn)品之間匹配的條件。當(dāng)指示器與待測(cè)農(nóng)產(chǎn)品服從任意多級(jí)反應(yīng)動(dòng)力學(xué)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(yīng)時(shí)間相等或二者等量線重合)時(shí),,即可使用該指示器預(yù)測(cè)對(duì)應(yīng)農(nóng)產(chǎn)品的品質(zhì)變化和貨架期,,此時(shí)二者的反應(yīng)速率函數(shù)存在一定比例關(guān)系。借助該方法推導(dǎo)出可以精準(zhǔn)指示科瑞森無核葡萄硬度的不同級(jí)反應(yīng)動(dòng)力學(xué)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.
