This 3D printed chicken breast was cooked with a Frickin’laser

Who is not dreaming Can I go home after a long day and get a 3D-printed meal of hot home-cooked meals, favored by a digital personal chef, with the push of a few buttons? It may obsolete microwave ovens and traditional freezing TV dinners. Columbia University engineers are trying to make that fantasy a reality. They understood how to 3D print and cook layers of puree chicken at the same time. Recent treatises Published in the journal npj food science.. Sure, it’s not at the same level as a start replicator that can synthesize a complete meal on demand, but it’s the beginning.

Co-author Hob Lipson runs the Creative Machines Lab at Columbia University, where the study was conducted.First introduced by his team 3D printing of food In 2007, I used the Fab @ Home personal fabrication system to create a multi-material edible 3D object with cake frosting, chocolate, processed cheese, and peanut butter. However, there is no commercial equipment that can print and cook the food layer at the same time.There have been some studies investigating how to cook food using laser, And Lipson’s team thought this might be a promising way to explore further.

“Printers can produce materials with millimeter accuracy, but I realized that there is no heating method with the same resolution.” Co-author Jonathan Brutinger said.. “Cooking is essential to the development of the nutrition, flavor and texture of many foods, and I wondered if we could develop a laser-based method to precisely control these attributes.” We used a blue diode laser (5-10 watts) as a good heat source, but we also experimented with near-infrared and mid-infrared lasers and conventional oven toasters for comparison.

Scientists bought raw chicken breast from a local convenience store and pureed it with a food processor for a smooth, even consistency. To prevent clogging, the tendons were removed, the sample was refrigerated and then repacked in a 3D printed syringe barrel. The cooker includes a high-power diode laser, a series of mirror galvanometers (devices that detect current by deflecting light rays), fixtures for custom 3D printing, laser shields, and removable for cooking 3D printing. I used a tray. chicken.

“During the first laser cooking, the laser diode was attached to a 3D-printed fixture, but as the experiment progressed, we moved to a setup where the laser was mounted vertically to the head of the extrusion mechanism,” the author writes. I have. “This setting allowed us to print and cook the ingredients on the same machine.” They also tried to cook the printed chicken after sealing it in a plastic package.

result? Laser-cooked chicken retains twice as much water as traditional cooked chicken and shrinks in half while maintaining a similar flavor. However, different types of lasers have different results. Blue lasers have proven to be ideal for cooking chicken internally under the surface, while infrared lasers have been excellent at surface-level browning and baking. For chicken in plastic packaging, the blue laser achieved a slight browning, while the near-infrared laser was more efficient at browning the chicken through the packaging. The team could even brown the surface of the packaged chicken with a pattern reminiscent of grill marks.
