Abstract
The idea of a Digital Product Passport (DPP) is to provide access to product specific data for actors and consumers in supply chains to satisfy different needs. Solutions for DPP exist in sectors other than food. However, literature on Digital Food Product Passport (DFPP) is very limited, and there are no clear guidelines regarding what data should be contained in a DFPP. Various platforms for traceability exist and traceability data obtained along food supply chains can be used as a fundamental data basis for DFPPs. In this paper we define what data to be included in a DFPP at different steps of the supply chains based on a collection of end-to-end traceability data. The focus is on how to use such data systematically in a DFPP and how to support the different stakeholders involved. We demonstrate how this approach can be applied to implement a blockchain-based DFPP for a fish supply chain.
