【摘要】 时间温度指示器技术是一种智能包装技术,它是一种简易的质量指示装置,可以对产品的整个货架期中的一些关键参数进行操纵、监控和记录,通过时间温度积累效应指示食品的温度变化历程和剩余货架寿命,从而提供食品质量变化信息。国外时间温度指示器已广泛运用于食品冷链运输和贮存。本文开发了以碱性脂肪酶化学反应体系为基础的时间温度指示器,同时测定了该时间温度指示体系在1.3℃,6.1℃,10.9℃,15.5℃,20.6℃,25.4℃下的反应速率,研究了其阿列纽斯动力学行为特性,测定了阿列纽斯动力学参数。实验表明,开发的碱性脂肪酶阿列纽斯反应活化能为45.07±2.25 kJ/mol.。在食品冷链贮运过程中有一定的应用前景。更多还原

【Abstract】 Time-Temperature Indicator(TTI) is an intelligent or smart package.It is a simple device that can be attached to food packaging to indirectly reflect the full or partial temperature history and quality status of the food product.TTI is utilized widely throughout food processing and distribution of cold chain.An alkaline lipase TTI has been developed,which based on the reaction between alkaline lipase and glycerol tributyrate.Experiments under several isothermal conditions(1.3℃,6.1℃,10.9℃,15.5℃,20.6℃,25.4℃) were conducted and the Arrhenius parameters of the TTI were derived.The developed TTI chemical reaction system showed an Arrhenius behavior,the activation energy was 45.07±2.25 kJ/mol.更多还原
