An Empirical Study for the Mobile Food Trace ability: Private Trace ability System for the White Gourd in Tianjin, China

As the food supply chain globalization became inevitable, transparency in the way agriculture was grown and handled throughout the supply chain process resulted in an important issue of ‘traceability’ in global food trade and safety for health management. Traceability in agriculture is faced with the technological challenges including food product label and identification, activity/process characterization, information systems for data capture, analysis, storage, and the integration of the overall traceable data for the supply chain, i.e., from farm to table. While some field data can be automatically acquired and transmitted by sensor networking, most agricultural activity information was recorded by manual handwriting for the traceability information systems. System architecture, operation scenarios, and the implementation examples for the mobile farming data collection system to automatically record the agricultural activities information for famers were proposed in this research. The farming information for farming activities is coded in two-dimensional labels of quick response (QR) codes. By scanning the proper operation labels, the corresponding farming data can be captured and uploaded simultaneously to the back-end web server. A collaborative research project for the traceability of white gourd planting in Tianjin was performed. The system can be implemented for public traceability system data collection and importing, as well as playing the roles of a private traceability system. The consumers’ confidence for healthy food choices with clear food traceability can be improved
