Food Safety Network for Detecting Adulteration in Unsealed Food Products Using Topological Ordering

The food supply chains are vast and involve a lot of persons. It is highly probable that any person within the food supply chain can add adulterant in the food product to gain more profit. Therefore, providing safe food through the chain is a big challenge. Though sealed food products can be tracked using various existing technologies such as using IoT devices or by chemical analysis, the traceability of unsealed food products is an unexplored domain. To address this problem, this paper proposes an adulterant check algorithm based on topological ordering. The proposed algorithm checks the adulterant nodes in the unsealed food product supply chain. Additionally, we also monitor the transactions in the unsealed food product supply chain and store the provenance information in the graph database. Thus, we provide a low cost, traceable, adulteration-free unsealed food supply chain.
