Now we’re cooking with lasers — ScienceDaily

Think about owning your have electronic private chef ready to prepare dinner up no matter what you want able to tailor the shape, texture, and flavor just for you and it can be all at the push of a button. Columbia engineers have been performing on performing just that, working with lasers for cooking and 3D printing know-how for assembling foods.

Under the guidance of Mechanical Engineering Professor Hod Lipson, the “Electronic Foods” workforce of his Resourceful Devices Lab has been making a entirely autonomous electronic private chef. Lipson’s team has been building 3D-printed foods since 2007. Considering that then, food stuff printing has progressed to multi-ingredient prints and has been explored by researchers and a handful of professional organizations.

“We famous that, although printers can create components to a millimeter-precision, there is no heating process with this identical diploma of resolution,” mentioned Jonathan Blutinger, a PhD in Lipson’s lab who led the job. “Cooking is important for nourishment, flavor, and texture advancement in quite a few foods, and we puzzled if we could create a process with lasers to precisely handle these characteristics.”

In a new review released Sept. one, 2021, by npj Science of Foods, the workforce explored different modalities of cooking by exposing blue light-weight (445 nm) and infrared light-weight (980 nm and ten.6 μm) to chicken, which they utilized as a design food stuff technique. They printed chicken samples (three mm thick by ~1in2 space) as a check bed and assessed a variety of parameters including cooking depth, colour advancement, dampness retention, and flavor dissimilarities concerning laser-cooked and stove-cooked meat. They learned that laser-cooked meat shrinks 50% a lot less, retains double the dampness content material, and displays comparable flavor advancement to conventionally cooked meat.

“In actuality, our two blind taste-testers chosen laser-cooked meat to the conventionally cooked samples, which displays promise for this burgeoning know-how,” Blutinger mentioned.

When Lipson and Blutinger are fired up about the opportunities of this new know-how, whose hardware and software package factors are relatively low-tech, they be aware that there is not but a sustainable ecosystem to guidance it. Lipson states that “what we nevertheless you should not have is what we contact ‘Food CAD,’ kind of the Photoshop of food stuff. We will need a substantial level software package that enables persons who are not programmers or software package developers to layout the foods they want. And then we will need a area where by persons can share electronic recipes, like we share music.”

Nonetheless, states Blutinger, “Foods is a little something that we all interact with and personalize on a every day basis — it looks only normal to infuse software package into our cooking to make meal generation far more customizable.”
