The 3D printing of food, it sounds interesting, but outside its decorative uses, the idea does not appeal to the majority of people out there. That’s not to say eventually, as the technology behind food printing matures, there 
As we mentioned in last month’s article, Biozoon targets a group of individuals who suffer from dysphagia, a condition which makes it difficult for a person to swallow their food. Instead of the way you and I may swallow, without even thinking about it, their larynx does not close properly. The condition is rather common among the elderly. It is estimated that 20% of individuals 50 years of age and older have difficulty swallowing to some degree, due to dysphagia.
An Entire Plate of 3D Printed Food
This makes the Biozoon technology perfect for the growing number of elderly individuals living in nursing homes and assisted living facilities. This week, further details emerged about the 3D printers that Biozoon had been working on. Apparently the printers are now spitting out all sorts of food puree. The printers which use 48 nozzles, via a jetting technology, combine puree of fresh ingredients like asparagus, chicken, pork, peas, pasta, and potatoes with a substance, which Biozoon prefers to keep a secret. It then prints those ingredients out in whatever shape the user desires. The secret substance allows for the puree to hold its shape, but at the same time melt in the mouth of whoever takes a bit. Sandra Forstner, the project manager for Biozoon, explained to Munchies, a food blog, how the printer is able to print in different shapes and textures.
“The printer is controlled by software where you can program, more or less, every kind of shape. The printing material itself will provide the taste since it’s normally spiced food purée, combined with the newly developed texturizing system that will be printed onto the plate. This means that with the printer we cannot adjust the taste, only the shape.”
According to Munchies, Biozoon is the coordinator of the project, however, several companies are involved, including Foodjet, who provides the ink jetting technology for the SmoothFood project in nursing homes. Biozoon is also responsible for developing texturing technologies for the printers. They currently have 4 different types of textures that they are able to achieve. They are able to produce foods with an airy foam, stable foam, gel, or thickened liquid textures. The ability to give different foods, different textures, goes a long way towards making the food almost as palatable as the solid alternative.
The project is currently under way in nursing homes as we write this article. All the food is prepared off-site, and shipped in as needed. Whether it’s a dessert, an appetizer, a main course or snack, there are 3D printing solutions for them all.
