The present manuscript aims at presenting some preliminary results from a literature review carried out on the existing documents dealing with Digital Twin models within the context of agri-food supply chain, in order to assess the state-of-art of such new technology for this promising field. The analysis considers both descriptive metrics (i.e., year of publication, research type, geographical origin and keywords analysis) and qualitative aspects (i.e., subdivision according to the supply chain phase involved and data-driven versus physic-based modelling of the Digital Twin solutions presented in the documents).
