Abstract
In modern society, food safety is becoming more and more important. The adoption of appropriate practices, such as the ones defined in the HACCP system, during food production, handling, preparation, and storage can reasonably guarantee food safety. However, it is not easy to apply HACCP methodologies in an automatic form, thus hindering its use in industrial machines. To solve this problem, the paper presents a novel solution adopting Internet of Things (IoT) and Blockchain technologies in the ice cream production process to automate the enforcement of HACCP directives. The new Carpigiani ice cream making machines exploit IoT for the automation of data gathering (in particular the temperature, that is of particular concern for dairy products) and a Blockchain solution for a tamper-proof and non-repudiable distributed storage of HACCP sensitive production data.
