The global food system is under increasing pressure due to population growth, environmental degradation, and climate change, necessitating sustainable solutions for agri-food preservation. This paper explores the development and implementation of advanced preservation systems that prioritize energy efficiency, food safety, and waste reduction. Key components such as innovative technologies, renewable energy adoption, food safety measures, waste reduction strategies, and efficient supply chain management are discussed. Case studies illustrate successful applications of these systems across different regions and sectors, highlighting their role in enhancing food security and sustainability.
