Is 3D printing the way forward for meals? Issues are already cooking

The Star Trek meals replicator it’s not. However researchers at Columbia College in New York have created a 3D printer that makes cheesecake.

Mechanical engineers within the Inventive Machines Lab at Columbia College have been experimenting with 3D-printed meals (“meals printers”) and laser cooking of meals since 2005. The Division of Protection has been working to develop 3D-printed MREs (Meals Prepared-to Eat) that sooner or later may very well be paired with wearable sensors to satisfy troopers’ dietary wants that day. NASA has additionally been experimenting with 3D-printed meals for astronauts on lengthy missions.

Till now, most 3D-printed meals have been made with raw components, the researchers say. However in analysis revealed just lately within the journal npj Science of Meals, the engineers describe how their 3D printer made a cheesecake from seven components: graham cracker, peanut butter, Nutella, banana puree, strawberry jam, cherry drizzle, and frosting.

A retrofitted, off-the-shelf 3D printer was used; the printing head may choose up any of the seven meals “inks” so as to add to the slice. A blue laser was used to brown and crust the highest floor of the graham cracker paste, Jonathan Blutinger, the lead creator of the research and a postdoctoral fellow within the lab, advised USA As we speak.

“We selected to print a slice of cheesecake as a result of it’s part of a bigger cake, it’s a shareable dessert, individuals have optimistic associations with it, and it’s usually a layered construction,” he stated. “That being stated, we didn’t embrace ‘cheese’ in any one of many components, so maybe we must always have renamed it.”

Printed cheesecake tastes ‘fairly candy’

The seven-layer cake was “to our information … a file setting variety of components in a single printed meals product,” the researchers wrote. “The design of our print grew to become just like establishing a house the place flooring, partitions, and ceilings being the muse (graham cracker) and internal swimming pools (Nutella and peanut butter) holding softer components inside (banana and jelly).”

It took a number of recipes to get a suitable slice with the jam overflowing the cheesecake’s basis at one level. They added graham cracker “partitions” to “higher help the construction,” the researchers stated. 

The ultimate end result, “tasted fairly candy — in additional methods than one,” Bluntinger stated. “Every ingredient hits your palette at completely different occasions, and made us notice that you could actually localize flavors all through the printed construction to get completely different taste sensations relying on the way you method consuming the dessert.”

3D-printed meals may make meals extra customizable — and presumably extra nutritious, the authors stated.

“With extra emphasis on meals security following the COVID-19 pandemic, meals ready with much less human dealing with may decrease the chance of foodborne sickness and illness transmission,” Bluntinger stated in a information launch describing the analysis.

3D printing is “notably sensible for the plant-based meat market, the place texture and taste must be rigorously formulated to imitate actual meats,” he stated.

Nonetheless, earlier than shoppers can participate within the 3D meals printing revolution, there’s going to must be “an ecosystem of supporting industries,” he stated.

The way forward for printing meals

You’ll probably pay extra to your first 3D meals printer than you probably did to your air fryer.

When the primary ones arrive, maybe in 5 years or so, they may probably are available at lower than $1,000, Bluntinger stated.

He expects eating places will start utilizing meals printers within the subsequent few years, “for digital gastronomy and one-off meals add-ons to class up a dish or make one thing aesthetically appetizing.”

The Inventive Machines Lab engineering lab has already constructed one other machine “that may print with as much as 18 components and prepare dinner with two completely different lasers,” Bluntinger stated. “So we’re working towards an 18-ingredient print that mixes paste components in addition to powder and liquids.”
