Now we’re cooking with lasers — ScienceDaily

Consider getting your personal electronic private chef ready to cook dinner up no matter what you want able to tailor the form, texture, and flavor just for you and it’s all at the press of a button. Columbia engineers have been functioning on undertaking just that, using lasers for cooking and 3D printing technologies for assembling foods.

Less than the steering of Mechanical Engineering Professor Hod Lipson, the “Electronic Foodstuff” group of his Creative Devices Lab has been developing a thoroughly autonomous electronic private chef. Lipson’s team has been producing 3D-printed foods considering that 2007. Given that then, food printing has progressed to multi-ingredient prints and has been explored by researchers and a number of business companies.

“We mentioned that, whilst printers can create components to a millimeter-precision, there is no heating system with this similar diploma of resolution,” mentioned Jonathan Blutinger, a PhD in Lipson’s lab who led the task. “Cooking is essential for diet, flavor, and texture development in lots of foods, and we questioned if we could build a system with lasers to specifically handle these characteristics.”

In a new review printed Sept. 1, 2021, by npj Science of Foodstuff, the group explored several modalities of cooking by exposing blue mild (445 nm) and infrared mild (980 nm and ten.six μm) to chicken, which they made use of as a design food technique. They printed chicken samples (3 mm thick by ~1intwo location) as a take a look at bed and assessed a assortment of parameters together with cooking depth, shade development, humidity retention, and flavor variations between laser-cooked and stove-cooked meat. They found out that laser-cooked meat shrinks 50% less, retains double the humidity material, and shows similar flavor development to conventionally cooked meat.

“In actuality, our two blind flavor-testers favored laser-cooked meat to the conventionally cooked samples, which shows assure for this burgeoning technologies,” Blutinger mentioned.

While Lipson and Blutinger are fired up about the options of this new technologies, whose hardware and software components are quite low-tech, they note that there is not nonetheless a sustainable ecosystem to support it. Lipson states that “what we still don’t have is what we call ‘Food CAD,’ sort of the Photoshop of food. We want a substantial level software that allows folks who are not programmers or software builders to style the foods they want. And then we want a spot the place folks can share electronic recipes, like we share tunes.”

Nonetheless, suggests Blutinger, “Foodstuff is one thing that we all interact with and personalize on a each day foundation — it would seem only all-natural to infuse software into our cooking to make meal creation additional customizable.”
