Abstract
The present invention relates to a system for providing food expiration date information using a TTI (time temperature integrator) and a method for providing food expiration date information using the same. The system for providing the food expiration date information and the method for providing the food expiration date information using the same of the present invention includes: an input unit for receiving TTI information, food information, and distribution history information; a calculation unit for producing a TTI indication value corresponding to an expiration date of the food; and an output unit which determines and outputs a color corresponding to the expiration date of the food among stages of colors which can be expressed through the TTI according to time and temperature conditions using the TTI indication value. According to desired embodiments, the present invention enables a consumer to confirm correctly the expiration date of the corresponding food by providing the TTI indication value corresponding to the expiration date of the food.
