In this paper, the traceability system for rice which is based on RFID technology is introduced. The traceability system plays an important role in the quality management for rice and rice-related food since this system can provide the information of all food chain (production, treatment, distribution and sales etc.) and more quickly identify the cause of the rice and rice-related accident. The main result of the this paper is the basic structure for the traceability system based on RFID technology. To show the implementation case based on this basic structure, the effectiveness of the traceability system is verified. In addition, the prerequisites condition for effective implementation is proposed.

This study was to investigate the physicochemical and sensory characteristics of snack with various amounts Cham chwi and oil. This result was used to determine the optimum condition of adding levels of Cham chwi and oil. Flavor, crispness, greasiness, oil absorption, expansion rate were selected as the physicochemical and sensory characteristics to determine the optimum conditions of the amount of Cham chwi and oil. The predicted values were obtained by the regression method of RSM(response surface methodology). Conditions were standardized with maximum range of expansion rate when expected value of crispness was more than five and expected value of greasiness was less five. The optimum conditions of Cham chwi snack was established as the 8.6% of Cham chwi and 7.6% of oil.
