Using lasers for cooking and 3D printing technology for assembling foods

A team of researchers at Columbia University in the US explored various modalities of cooking food by exposing blue light (445 nm) and infrared light (980 nm and 10.6 μm) to chicken, which they used as a model food system.

They printed chicken samples (3 mm thick by ~1 in 2 area) as a test bed and assessed a range of parameters including cooking depth, color development, moisture retention, and flavor differences between laser-cooked and stove-cooked meat.

They discovered that laser-cooked meat shrinks 50% less, retains double the moisture content, and shows similar flavor development to conventionally cooked meat.

While the researchers are excited about the possibilities of this new technology, whose hardware and software components are fairly low-tech, they note that there is not yet a sustainable ecosystem to support it.

“What we still don’t have is what we call ‘Food CAD,’ sort of the Photoshop of food. We need a high level software that enables people who are not programmers or software developers to design the foods they want. And then we need a place where people can share digital recipes, like we share music”, said the researchers.
