Nowadays, as people become more health-conscious, adopting a healthy and balanced diet has become increasingly important for a better quality of life. A good diet not only helps to prevent and fight diseases, but also contributes to overall well-being. At the same time, consumers are concerned about climate change and the sustainability of the planet. Consequently, consumers are paying more attention to the food they consume, seeking products that offer nutritional value and sustainability rather than just brand recognition. Portugal is one of the largest olive oil producers in the world, and olive oil is a fundamental component of the Mediterranean diet. The nutritional value of olive oil is directly linked to every stage of the product's value chain, from cultivation to consumption. To ensure that consumers have access to reliable and accurate information about the quality of the olive oil they purchase, it is important to establish traceability in the production chain. By doing so, consumer confidence can be consolidated. This study focuses on traceability in the olive oil production chain, as well as social and environmental sustainability indicators and quality indicators. The goal is to create a solution that utilizes Blockchain technology and Smart Contracts to enable more reliable and transparent information about olive oil production and quality to be easily accessible to consumers. This case study is important because it highlights the need for greater transparency in the food production chain, as well as the benefits of utilizing new technologies like Blockchain to improve transparency and trace ability. It also demonstrates the significance of sustainability in the production of food products, and how it can impact both the environment and consumer health.
