Abstract:
1. A system for monitoring food quality, the system comprising: a sensor tag, when transporting of the food starts, the sensor tag senses an environmental factor at preset time intervals, and when the sensed environmental factor value is not included in a preset environmental factor value range of the food, adjusting a time interval to sense the environmental factor, and transmits an environmental factor value sensed, a time sensing the environmental factor and product information on the food to a sensor tag reader, the sensor tag being attached to a container or palette on which food is stacked; a sensor tag reader for transmitting the environmental factor value sensed by the sensor tag, a time sensing the environmental factor, and product information on the food transmitted through the sensor tag to a distribution company server; a distribution company server for transmitting the environmental factor value sensed by the sensor tag, a time sensing the environmental factor, and product information on the food transmitted through the sensor tag reader to a food quality monitoring server; a food quality monitoring server for measuring a food quality index by using an equation including at least one of values changed per unit time in a particular temperature for at least one of the quality indexes of each food, said quality indexes including any of a reaction speed constant, a reaction degree, activation energy, a frequency constant, a temperature coefficient and a mean kinetic temperature, based on at least one of the environmental factor values sensed by the sensor tag, the time sensing the environmental factors, and the product information on the food transmitted through the distribution company server; and transmitting bar code information or electronic tag information corresponding to the food and the measured quality index to the distribution company server.
