摘　　要：提出了一种基于等量线匹配的时间温度指示器(TTI)评估方法。首先,从理论方面论证了等量线方法的可行性,然后以不同温度条件下的4种TTI响应值与玫瑰香葡萄硬度变化进行了验证与评估。研究结果表明,Vitsab M25-2型TTI最适于监测玫瑰香葡萄的品质变化,此结果与经过变温方案检验的反应动力学方法的评估结果一致。同时发现,TTI和玫瑰香葡萄等量线之间的差异与其反应活化能之间的差别呈正相关关系,进一步验证了等量线方法的可靠性。In view of the situation that the kinetic model which is necessary for the traditional time temperature indicator （TTI） selection method is complex and inaccurate for the multiple regressions, a convenient and intuitive method based on the contour lines was proposed. The method is demonstrated in theory, and analyzed with the traditional method through an experiment about Muscat Hamburg grape and four kinds of TTI. The result shows that the TTI of Vitsab M25 - 2 could be considered as the best candidate to monitor firmness losses of Muscat Hamburg, and this is similar to the result from the traditional kinetic model. Meanwhile, the differences of the contour lines between the grape and TTIs are positive correlated with the differences between the activation energy of them, which confirms the reliability of the TTI selection method based on contour lines.
