Method and system for monitoring quality of food
First Claim
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.

Abstract
Disclosed is a method of monitoring food quality including (a) receiving an environmental factor value sensed during transporting by a moving sensor tag attached to a container or palette on which a plurality of food is stacked, a time value sensing the environmental factor, and food information from a distribution company server; (b) receiving an environmental factor value sensed by a fixed sale sensor tag which matches the food information stored in the moving sensor tag, a time value sensing the environmental factor, and food information from the distribution company server; (c) measuring a current quality index for each individual quality analysis item and a total quality index based on the food information sensed by the moving sensor tag and the fixed sale sensor tag, the environmental factor values, and the time values sensing the environmental factors; (d) setting price of the food based on the measured quality index for each individual quality analysis item and total quality index; and (e) transmitting bar code information or electronic tag information (food information) corresponding to a plurality of food which matches inherent IDs of the fixed sale sensor tags, the quality index for each individual analysis item of the food, the total quality index, and the price of the food to the distribution company server.

5. The system of claim , wherein the sensor tag does not store the sensed environmental factor value in the memory when the sensed environmental factor value is equal to a previously sensed environmental factor value and stores the sensed environmental factor and the time of sensing the environmental factor in the memory when the sensed environmental factor value is different from the previously sensed environmental factor value.
