基于区块链技术的食品质量安全管理系统及在大米溯源中的应用研究

The Food Quality Safety Management System Based on Block Chain Technology and Application in Rice Traceability

随着消费者对食品质量安全的要求不断提高,快速响应、高效控制、安全保障成为现代食品安全领域的重要课题。由于现有技术存在优质原始信息少、信息不对称、可靠性差等问题,以及缺乏准确高效的食品安全事件预测和溯源技术,安全管控的效果难以满足社会需求。本文通过区块链技术,建立去中心化、低成本高效率、信息可靠的执行环境,构建从农田到餐桌的大米全产业链质量全息数据库,采用具基于危害因子的食品风险评估与安全溯源技术,设计多角色、多环节和多要素的智能管理系统,以实现食品质量安全的高效管控。

With the consumers’ demands for food safety constantly improving, Rapid response, efficient control and security guarantee become an important subject in the field of modern food safety. Due to fewer existing high-quality original information technology, information asymmetric, poor reliability problem, and lack of food safety events forecast and traceability technology, the effect of safety control is difficult to meet the demand of current society. This paper constructed the decentralization, cost-effective and reliable information of execution environment based on the blockchain technology. Building a holographic database of the rice whole industry chain from farmland to table, adopting the food risk assessment and safety traceability technology based on the hazard factor to design the multi-role,multi-link and multi-factor intelligent management system to realize the efficient control of food quality and safety.
