Now we’re cooking with lasers — ScienceDaily

Consider possessing your possess digital individual chef completely ready to cook up regardless of what you want in a position to tailor the condition, texture, and flavor just for you and it’s all at the press of a button. Columbia engineers have been operating on carrying out just that, working with lasers for cooking and 3D printing technologies for assembling food items.

Underneath the steerage of Mechanical Engineering Professor Hod Lipson, the “Electronic Foods” crew of his Resourceful Equipment Lab has been constructing a thoroughly autonomous digital individual chef. Lipson’s team has been establishing 3D-printed food items considering that 2007. Because then, foods printing has progressed to multi-component prints and has been explored by researchers and a number of commercial providers.

“We mentioned that, even though printers can generate elements to a millimeter-precision, there is no heating method with this exact same diploma of resolution,” reported Jonathan Blutinger, a PhD in Lipson’s lab who led the project. “Cooking is vital for nourishment, flavor, and texture progress in quite a few food items, and we wondered if we could build a method with lasers to specifically manage these characteristics.”

In a new study released Sept. 1, 2021, by npj Science of Foods, the crew explored numerous modalities of cooking by exposing blue light-weight (445 nm) and infrared light-weight (980 nm and ten.six μm) to chicken, which they applied as a design foods program. They printed chicken samples (3 mm thick by ~1in2 spot) as a examination bed and assessed a variety of parameters which includes cooking depth, color progress, moisture retention, and flavor dissimilarities in between laser-cooked and stove-cooked meat. They learned that laser-cooked meat shrinks 50% much less, retains double the moisture information, and shows comparable flavor progress to conventionally cooked meat.

“In fact, our two blind style-testers preferred laser-cooked meat to the conventionally cooked samples, which shows assure for this burgeoning technologies,” Blutinger reported.

Even though Lipson and Blutinger are fired up about the prospects of this new technologies, whose hardware and computer software components are fairly lower-tech, they be aware that there is not however a sustainable ecosystem to assist it. Lipson states that “what we still never have is what we connect with ‘Food CAD,’ type of the Photoshop of foods. We need a significant degree computer software that enables people who are not programmers or computer software developers to design the food items they want. And then we need a location where by people can share digital recipes, like we share new music.”

Still, states Blutinger, “Foods is anything that we all interact with and personalize on a day by day foundation — it appears to be only all-natural to infuse computer software into our cooking to make food generation additional customizable.”
