The time-temperature indicator (TTI) has been attracted attention as a technology that can visualize the changes in the characteristics of growth, quality, storage, and food processing for agricultural products. Therefore, in this study, color change characteristics were analyzed and a reaction tool was developed as basic data for producing a time-temperature indicator based on the Maillard reaction. The color of the Maillard reaction solution was changed colorless through, light blue, and brown to black and showed a very pronounced color change. And the rate of change in the reaction solution was increased in higher concentrations. Moreover, the time for the optical density to reach the highest point was shortened in the high concentration condition, and the slope of the change curve increased. Therefore, it was determined that the color change characteristics of the reaction solution by reaction concentration control could show a similar trend to the quality characteristics of agricultural products. In this result, the color change of the Maillard reaction-based time-temperature indicator would provide a lot of information about agricultural products such as ripen quality, rate of change, and storage deadline, etc. In addition, the prepared reaction tool was easy to manufacture, and the Maillard reaction solution was efficiently protected and the color change was clearly confirmed with high transparency. Therefore, it was determined that the developed reaction tool could be used as a time temperature indicator based on the Maillard reaction.
