Abstract:
1. A system for providing food shelf-life information using a time-temperature integrator (TTI), the system comprising: an input unit in which TTI information regarding a TTI itself, food information regarding a food to which the TTI is to be attached, and distribution history information regarding the food before the TTI is attached to the food are input in advance; a calculation unit which receives the TTI information, the food information, and the distribution history information from the input unit and calculates a TTI indication value corresponding to a remaining shelf-life of the food based on the received information; and an output unit which receives the TTI indication value from the calculation unit and designates a color corresponding to the remaining shelf-life of the food from colors for each step that can be indicated by the TTI based on time and temperature conditions using the received TTI indication value and displays the color, wherein the TTI is any one selected from the group consisting of an enzymatic TTI, a diffusion-based TTI, a photochemical TTI, a polymer-based TTI, and a microbial-based TTI, wherein when the TTI is the diffusion-based TTI, the calculation unit calculates the TTI indication value using the following Formula A: in Formula A, W is a TTI indication value, k is a reaction rate constant, k wherein when the TTI is the photochemical TTI, the calculation unit calculates the TTI indication value using the following Formula B: In Formula B, W is a TTI indication value, I wherein when the TTI is the polymer-based TTI, the calculation unit calculates the TTI indication value using the following Formula C: in Formula C, W is a TTI indication value, k
