A technological quality control system for rice supply chain

Rice quality affects social stability, consumer health, and corporate brand benefit. The traditional supply chain traceability management system is centralized, monopolized, asymmetric, opaque. It the main factor leading to frequent food safety incidents. This paper proposes a technological control for rice protect products safety. Firstly, it adopts risk assessment mechanism prevent hazard factors in production processing. Then, spoiled from endangering consumers’ health reduce waste, explores shelf life model of predict remaining products. Finally, this constructs decentralized based on blockchain IoT, which enables consumers access real information helps supervisors monitor chain.
