What is 3D Printed food

With technological developments in recent years, the food industry has benefited from new and exciting innovations. 3D food printing is one of these, and it’s a process that’s used to manufacture food products with additive manufacturing techniques. 3D printing in the food industry most commonly uses food-grade in-vitro material. This is then pushed through a nozzle and builds up layers to create the final product. The foods that can be produced in this way are mainly limited by the production process but include patties and in-vitro meat. Here we’re going to explore how does 3D printed food work and what is 3D printed food made of.

3D Printed meat (in vitro meat)

One example of 3D printed food that’s edible is 3D printed meat, which is used to in vitro meat. If you are wondering how does in vitro meat work and what is in vitro meat, it’s actually a process that’s used to create cultured meat. Using tissue-engineering, this process creates meat without killing an animal to create the food product. The starting cells for the process are taken from the anima. These cells are placed into a culture media. Then they begin to grow without any further input from the animal. The theory behind this process is that in the future, it could help to supply the global food chain and could offer us financial, health, environmental, and animal welfare benefits.

Due to this only being a more recent development, many individuals ask how expensive is in vitro. This process can be used to create steaks, sausages, burgers, or chicken nugget. While the process is reasonably simple, it’s still not a mainstream offering today. Further research and development are still being undertaken to create a viable alternative to meat in the future. However, once the taste and cost of meat can be matched, in vitro meat will be a certainly exciting option for future generations.

3D Printing in food industry

3D food printing was first tested in 2006 at Cornell University. Their food printing machine worked to create chocolate, cookie dough, and cheese. This process usually creates layers of material, which helps to create the unique shape of the item. More advanced 3D printed food examples today have the recipes already loaded into the machine. This allows users to process the food order from a computer or smartphone remotely. 3D printed food can be completely customized to fit your needs. Also the shape, color, flavor, texture, and nutritional values can be altered as required.

3D food printing has not become an affordable option that’s available worldwide yet. However, it’s being used for space exploration and within the healthcare industry. When it comes to 3D printing food, there are three different areas that will impact the process and how effective it is. Firstly, the materials and ingredients must be specially chosen to ensure they are the correct viscosity and texture for the process to be successful. The printing speed and distance can be adjusted to create different items, and then various post-processing methods offer different finishes. To complete the food printing machine process, the item has to be fried, baked, or microwaved before it can be consumed, depending on the raw material.

If you are wondering if 3D printers can print food and what type of food they can create, it all depends on the type of printing process that’s being used. Extrusion-based printing ejects materials in layers through a nozzle. And the materials that are used with this method will need to be soft enough to make their way out of the nozzles. However, they’ll also need to be viscous enough to keep their shape once the printing process is complete, which is why protein or sugar may be added. Common materials that are used for this type of 3D printing include jelly, cheese, mashed potatoes, and frosting.

Solid structures from powdered ingredients

To create products from powdered ingredients, selective laser sintering will be used. The materials are bonded together, which results in a solid structure. Sugar, chocolate powder, or protein powder are often used in this process to create 3D food products. Finally, inkjet printing needs ingredients that have a low viscosity. Sauces and colored food ink can be added throughout this process. It’s mainly used for surface filling following the creation of the initial 3D food item. For example, if you’ve created a cookie or piece of candy, you can add a wide range of colors to create a unique image on the top of the item. There are inkjet printers available today for both household and commercial use or industrial printers for larger quantities.

The problems to be solved

Following any of these processes, the 3D printed food may not be ready to eat yet. To ensure this technologically advanced food is safe for human consumption, food is often baked, fried, or cleaned before it can be served or packaged up. One of the top concerns and an ongoing area of research is in regard to deformities. This often appears in this final stage. Additives sometimes need to be added to the food products to ensure they retain their shape during the printing stage and then also be cooked once. As you can tell, the majority of food that’s produced in this manner isn’t the most nutritionally dense, which is why additional ingredients may be added to create a healthier source of food that can be enjoyed as part of a balanced diet.

3D printing in the food industry is undoubtedly an exciting development and one that we look forward to in the upcoming years. With food printer machines becoming more commonplace today, no doubt we’ll start to see more products produced in this way. We’ll be following 3D printed food developments carefully and look forward to seeing this become an innovative solution for environmental and sustainability concerns in the future.
