    摘要:

    時間-溫度指示器(TTI)是一種可以跟蹤冷鏈物流溫度歷程的智能裝置,可以指示相應(yīng)的農(nóng)產(chǎn)品品質(zhì),。但現(xiàn)有的TTI匹配條件在一定程度上限制了TTI的應(yīng)用范圍,,即使TTI滿足了傳統(tǒng)匹配條件的要求,,但應(yīng)用效果也會受到農(nóng)產(chǎn)品采收品質(zhì)波動的影響,。通過使用反應(yīng)動力學方程和等量線方法,,在原有的匹配過程中引入了TTI的校準過程,,并借此推導TTI匹配所需的基本條件,,以及校準過程所需的參數(shù),。結(jié)果表明,,TTI匹配性判斷所需的基本條件僅為農(nóng)產(chǎn)品品質(zhì)與TTI的反應(yīng)活化能相等,或兩者等量線存在比例關(guān)系,。在此前提下,,利用公式推導或等量線的繪制過程,可以求得靜態(tài)校準和動態(tài)校準時所需的相關(guān)參數(shù),,經(jīng)過校準后的TTI即可與對應(yīng)的食品完成匹配,。校準過程的引入可以顯著擴大TTI的適用范圍。除此之外,,動態(tài)校準模型還可以縮小處于變化中的TTI和農(nóng)產(chǎn)品對應(yīng)品質(zhì)之間的差值,,提高TTI指示貨架期的精確性。最后,,通過使用兩種酶型TTI,、兩種不同激活條件的化學型TTI和玫瑰香葡萄進行驗證實驗,實驗結(jié)果證明經(jīng)過合理校正之后TTI的等量線普遍與玫瑰香葡萄的品質(zhì)等量線更接近,,對其指示效果精準,。

    Abstract:

    Time temperature indicator (TTI) is an intelligent tool to monitor and record directly the time-temperature history of cold chain and indicate quality of corresponding agriculture produce. Because of the restriction of classic matching condition, TTI has not been widely used in a wide variety of agricultural produces. Even when the TTI satisfies the conditions, the reliability of application is significantly affected by the unstable primary quality of agricultural produces. The application of TTI is expanded through adjusting its parameters, and determining the requirements for matching with agricultural produces and the calibration procedure of TTI. The result deduced through the reaction kinetics equations and contour diagram indicated that the only matching condition was activation energy of TTI should equal to the parameter of agricultural produce, or there existed a proportional relationship between the contour lines of the two products. Besides, an adjusting process of TTI should be used with the new matching condition together. Considering a change of the state of TTI and agricultural produces, the calibration process was divided into two parts: first was the static model with the two produces’ state which were static, and the second was the dynamic model with both of the two produces were in constant change. It provided corresponding theory and methods by using the Arrhenius equations and contour diagram for the two calibration process respectively. These calibration methods can expand the application of TTI and improve the precision and reliability of monitoring the quality of agricultural produces. Finally, the validity and reliability of the calibration theory were illustrated with an example by using two types of enzymatic TTIs, two types of chemical TTIs and Muscat grape.
