Abstract

Industrial food processing plays a crucial role in the global food supply but faces significant sustainability challenges, including high energy consumption, excessive waste, and greenhouse gas emissions. This study used a literature review, analyzing 32 articles between 2010 - 2024. This study explores sustainable food processing practices that can enhance efficiency while mitigating environmental impacts. It highlights the urgent need for innovative solutions, such as renewable energy integration, energy recovery systems, and non-thermal preservation methods, which can reduce resource consumption and improve food safety. It also addresses the importance of waste reduction strategies and eco-friendly packaging to minimize plastic pollution. The role of advanced technologies, including IoT and AI, is emphasized for optimizing operations and reducing energy use. Moreover, regulatory frameworks and policies, such as the Paris Agreement, are vital in promoting sustainable practices within the food industry. However, barriers to adopting new technologies, such as high initial costs and consumer resistance, must be addressed through government incentives and educational initiatives. The food processing sector can achieve a more sustainable future by fostering stakeholder collaboration and increasing consumer awareness. This review aims to contribute valuable insights and recommendations for future research, emphasizing the collective responsibility of industry and academia in achieving sustainability in food systems.
