Visualize having your personal electronic private chef all set to prepare dinner up whatsoever you want able to tailor the shape, texture, and flavor just for you and it truly is all at the thrust of a button. Columbia engineers have been performing on accomplishing just that, applying lasers for cooking and 3D printing engineering for assembling foods.
Beneath the steerage of Mechanical Engineering Professor Hod Lipson, the “Electronic Food items” team of his Inventive Equipment Lab has been building a fully autonomous electronic private chef. Lipson’s group has been producing 3D-printed foods considering that 2007. Considering the fact that then, foodstuff printing has progressed to multi-component prints and has been explored by researchers and a handful of professional businesses.
“We observed that, though printers can create ingredients to a millimeter-precision, there is no heating approach with this same degree of resolution,” mentioned Jonathan Blutinger, a PhD in Lipson’s lab who led the venture. “Cooking is vital for nutrition, flavor, and texture progress in lots of foods, and we wondered if we could produce a approach with lasers to exactly management these characteristics.”
In a new study published Sept. one, 2021, by npj Science of Food items, the team explored several modalities of cooking by exposing blue light-weight (445 nm) and infrared light-weight (980 nm and ten.six μm) to chicken, which they made use of as a model foodstuff process. They printed chicken samples (3 mm thick by ~1in2 spot) as a check mattress and assessed a variety of parameters such as cooking depth, shade progress, humidity retention, and flavor variations amongst laser-cooked and stove-cooked meat. They identified that laser-cooked meat shrinks 50% significantly less, retains double the humidity material, and demonstrates equivalent flavor progress to conventionally cooked meat.
“In actuality, our two blind flavor-testers most popular laser-cooked meat to the conventionally cooked samples, which demonstrates guarantee for this burgeoning engineering,” Blutinger mentioned.
Whilst Lipson and Blutinger are energized about the opportunities of this new engineering, whose hardware and software package factors are reasonably low-tech, they take note that there is not but a sustainable ecosystem to guidance it. Lipson states that “what we however will not have is what we get in touch with ‘Food CAD,’ type of the Photoshop of foodstuff. We will need a higher level software package that enables people who are not programmers or software package builders to layout the foods they want. And then we will need a location where by people can share electronic recipes, like we share new music.”
Still, claims Blutinger, “Food items is some thing that we all interact with and personalize on a day by day foundation — it appears to be only purely natural to infuse software package into our cooking to make food creation more customizable.”
