Could 3D food printing help to improve the food supply chain resilience against disruptions such as caused by pandemic crises?

The ongoing COVID-19 pandemic is having a tremendous effect on the current food system. The situation urges us to face many issues never experienced before, aimed at mitigating a multitude of sanitary and social risks. The current pandemic has affected the food system in many ways: significant changes in dietary habits and in the health status of people; the food chain is broken, which has an effect on food security (including making it difficult to find or to buy fresh food at affordable prices); unemployment or underemployment is rising due to the damages of the food sector; there is a lack of food-socialising events which has an effect on people's mental status; and there are concerns about food safety. To mitigate all these issues, the implementation of innovative technologies urges. We have mapped the scientific studies and online information on 3D food printing (3DFP) about the effects of 3DFP on the food system and people's health when adopted in food industry, restaurants, hospitals, schools, offices, homes, etc. Finally, this information has been examined in light to the future challenges of the food chain also considering the ongoing COVID-19 pandemic, demonstrating its potential benefits to mitigate this and future pandemics.
