Think of having your own digital personal cook; prepared to prepare whatever you desire; able to customize the shape, texture, as well as taste just for you; and also it’s all at the press of a switch. Columbia designers have been dealing with doing simply that, making use of lasers for food preparation as well as 3D printing modern technology for constructing foods.

Under the support of Mechanical Design Teacher Hod Lipson, the “Digital Food” team of his Creative Devices Lab has actually been developing a totally autonomous digital individual chef. Lipson’s group has been creating 3D-printed foods given that 2007. Ever since, food printing has proceeded to multi-ingredient prints and has been explored by researchers and a few commercial business.

“We noted that, while printers can produce ingredients to a millimeter-precision, there is no heating technique with this exact same degree of resolution,” claimed Jonathan Blutinger, a PhD in Lipson’s lab that led the job. “Food preparation is necessary for nutrition, taste, and structure growth in several foods, and we asked yourself if we can create a method with lasers to exactly control these attributes.”

In a new research published Sept. 1, 2021, by npj Science of Food, the team explored different methods of food preparation by exposing blue light (445 nm) and also infrared light (980 nm and 10.6 μm) to chicken, which they utilized as a design food system. They printed poultry samples (3 mm thick by ~ 1in2 location) as an examination bed and evaluated a range of criteria consisting of food preparation depth, shade development, dampness retention, and flavor distinctions in between laser-cooked and stove-cooked meat. They found that laser-cooked meat shrinks 50% much less, maintains double the dampness content, as well as reveals similar flavor growth to conventionally cooked meat.

“In fact, our 2 blind taste-testers preferred laser-cooked meat to the traditionally prepared samples, which reveals guarantee for this blossoming modern technology,” Blutinger claimed.

While Lipson as well as Blutinger are excited about the possibilities of this brand-new technology, whose hardware and software components are rather low-tech, they note that there is not yet a sustainable environment to sustain it. Lipson mentions that “what we still do not have is what we call ‘Food CAD,’ kind of the Photoshop of food. We need a high level software that makes it possible for people that are not programmers or software developers to create the foods they desire. And afterwards we require a place where people can share digital dishes, like we share songs.”

Still, claims Blutinger, “Food is something that we all interact with as well as individualize each day– it seems only all-natural to instill software application into our cooking to make meal production extra adjustable.”
