Realizing edible data embedding!

Until now, information such as the expiration date, place of origin, and contained allergens of food has typically been printed on packaging or other items outside of the food itself. If data could be embedded directly into the food, it would allow for the verification of this information even after the packaging has been opened, right up until the moment of consumption. However, printing on the surface of the food would alter its appearance. On the other hand, in the field of food tech, which utilizes the latest technologies in food, food 3D printers are gaining attention as a new cooking technique. By using food 3D printers, it has become possible to design not only the external shape of food but also its internal structure freely. This research achievement enables the digital transformation (DX) of food itself, improving food safety through enhanced food traceability. Information such as expiration dates and contained allergens is usually lost after removing the packaging, but it has now become possible to read this information right up until consumption, thereby enhancing food safety.
