3-D Printed Food with Custom Taste and Texture: Could It Change How We Eat?

Researchers have 3-D printed food with customized texture and body absorption characteristics. 

Imagine a home appliance that, at the push of a button, turns powdered ingredients into food that meets the individual nutrition requirements of each household member. Although it may seem like something from science fiction, new research aimed at using 3-D printing to create customized food could one day make this a reality.

A: Food materials are pulverized under ultra-low temperature close to -100 degrees Celsius. B: Micro-sized food materials are reconstructed into a porous film-shaped material by jetting bonding an agent under optimized water content and heat conditions. The process to build film-type materials is repeated layer by layer to form to a three-dimensional food block. C: The exterior of foods and internal microstructure of a food block with specific porosity is designed to give texture with controlled human body absorption while eating and ingesting.

Jin-Kyu Rhee, associate professor at Ewha Womans University in South Korea, discussed his new research and the potential of 3-D printing technology for food production at the American Society for Biochemistry and Molecular Biology annual meeting during the 2018 Experimental Biology meeting to be held April 21-25 in San Diego.

"We built a platform that uses 3-D printing to create food microstructures that allow food texture and body absorption to be customized on a personal level," said Rhee. "We think that one day, people could have cartridges that contain powdered versions of various ingredients that would be put together using 3-D printing and cooked according to the user's needs or preferences."

3-D printing of food works much like 3-D printing of other materials in that layers of raw material are deposited to build up a final product. In addition to offering customized food options, the ability to 3-D print food at home or on an industrial scale could greatly reduce food waste and the cost involved with storage and transportation. It might also help meet the rapidly increasing food needs of a growing world population.

For the new study, the researchers used a prototype 3-D printer to create food with microstructures that replicated the physical properties and nanoscale texture they observed in actual food samples. They also demonstrated that their platform and optimized methods can turn carbohydrate and protein powers into food with microstructures that can be tuned to control food texture and how the food is absorbed by the body.

"We are only in early stages, but we believe our research will move 3-D food printing to the next level," said Rhee. "We are continuing to optimize our 3-D print technology to create customized food materials and products that exhibit longer storage times and enhanced functionality in terms of body absorption."

Jin-Kyu Rhee present edthe research from 12:45-1:30 p.m. Tuesday, April 24, in Exhibit Halls A-D, San Diego Convention Center (poster B284 801.9) (abstract).

Gold, Diamond Companies Joined IBM to Develop Blockchain Technology


Gold and diamond companies including Berkshire Hathaway (NYSE:BRK-A)Richline Group Inc joined with IBM to develop blockchain technology to track the origin of jewelry and ensure it is ethically sourced, the companies said Thursday.

The joint initiative, TrustChain goal to make it easier for consumers to track diamonds and precious metals through the various steps of the supply chain as they become finished pieces jewelry, the companies said.

The technology will initially help track 6 styles of diamond and gold engagement rings and is expected to be available to consumers by the end of Y 2018, the companies said.

Other firms involved in the initiative include precious metals refiner Asahi Refining, jewelry retailer Helzberg Diamonds, precious metals supplier LeachGarner and 3rd-party verification provider UL.

Blockchain 1st emerged as the system powering cryptocurrency Bitcoin (BTC) is a shared database that is maintained by a network of computers connected to the Internet.

Because it makes it easier for multiple parties to jointly create and update tamper-proof records, the firms involved in the project believe it is well suited to securely and efficiently track and prove the origin and ethical sourcing of jewelry.

Berkshire’s Richline Group had previously attempted to create a similar database using different technology, but the process was heavily manual and prone to inaccuracies.

The TrustChain platform was tested last week to track the provenance of a diamond ring across the supply chain.

Other companies in the industry have started to explore using blockchain technology.

Anglo American’s (NYSE:AU) diamond unit De Beers said in January that it aims to create an industry wide blockchain to track gems each time they change hands starting from the moment they are dug from the ground.

Companies in other sectors have also been seeking to adapt blockchain help simplify and reduce the costs some of their most data processes.

Supply chain management is one of the areas where businesses believe blockchain holds the most promise, as it involves numerous parties and is still very manual.

IBM is also working with large food retail companies on a blockchain platform to help track food supply chains and improve safety. Source: Live Trading News
