Fermentation Food Monitoring System using the Smart RFID Sensor Tag

People in the world made a unique fermented food for a long time. These fermented foods have been increased interest to people health in recent years. These fermented foods can be caused a disease in the event of misunderstood difference between fermentation and putrefaction. In addition consumers can’t know degree of different between fermentation and putrefaction. Therefore, the monitoring system which can predict a fermented foods change is needed in the distribution process in order to ensure quality and maturity. In this paper, the system which the can be monitored maturity and quality for fermented foods was proposed for consumers' health and safety. We measured the pH and temperature in order to maturity and quality of fermented food. The proposed system consists of RFID Tag, pH sensor, temperature sensor, RFID reader and server. In order to we confirm the usefulness of the proposed system, we are monitored fermented state and quality about a kimchi and a rice wine of Korea representative fermented foods.
