According to Agricultural Statistics for 2011 of Council of Agriculture, the value of fruit category exports got greatest growth recently and the value of exports was 2,797,734 tonnes in 2011 Because Taiwan geography location, the agricultural products were trasported by cold chain logistics and Taiwan launched an official reform program for traditional industries in 2013 which will vigorously promote the preservation and traceability of the cold chain logistics during it. Most perishable food was delivered and trasported by cold chain logistics, although it adapated a complete environment monitoring, but it still got 5°C temperature difference with pratice in Taiwan[3][7] and it took 85% time of overall process within 3°C temperature range. It can be seen from the practice, there were some interferences from environmental factors. The purpose of this study is understands the interferences from environmental factors in practice process by RFID sencor tags with SQL then develops a predicte model of shelf life with back-propagation neural algorithm. In this study, it compares the performerce among difference train function as Steepest Descent Method, Steepest Descent Method with momentum and Levenberg-Marquardt (LM), then the Levenberg-Marquardt train function with relevant parameters get a best performerce in finale. RFID food traceability system could not only control production origins but understand their shelf life after cold chian logistic. It increased the added value of RFID traceability system if they can combine the results of this study.
