3-D Printable Food Gets Funding From NASA 242

Posted by Soulskill from the enjoy-a-tasty-extrudel dept.
cervesaebraciator writes "According to Quartz, '[Anjan Contractor's] Systems & Materials Research Corporation just got a six month, $125,000 grant from NASA to create a prototype of his universal food synthesizer. But Contractor, a mechanical engineer with a background in 3-D printing, envisions a much more mundane — and ultimately more important — use for the technology. He sees a day when every kitchen has a 3-D printer, and the earth's 12 billion people feed themselves customized, nutritionally-appropriate meals synthesized one layer at a time, from cartridges of powder and oils they buy at the corner grocery store. Contractor's vision would mean the end of food waste, because the powder his system will use is shelf-stable for up to 30 years, so that each cartridge, whether it contains sugars, complex carbohydrates, protein or some other basic building block, would be fully exhausted before being returned to the store.' No word yet on whether anyone other than the guy trying to sell the technology thinks it'll make palatable food."

        You may well be able to imagine that.... but at our present technology, what you get from heating one bit more than another is one hot bit and one cold bit.

        Texture is independent of heat... The use of heat in cooking will create different textures, but the texture essentially comes from the base material, although carbonised black goo you can pretty much make with any starting material - generally this is considered a mistake.

    Other than astronauts and zombie bunkers, I don't see the appeal. We already pack strange synthetic food into cans that have more than enough shelf life for most occasions. I'd be willing to bet I'd prefer the taste and texture of said canned goods to whatever playdough this thing prints out. The only food that occasionally gets wasted around my house is fresh fruits, vegetables, and meat; none of which would really be replaced by this technology. If you find a way to print something more palatable that what I can already get from a can, then let me know.

      A great example I have seen showing processed vs non-processed foods is to simply put the food in a bowl of water. A lot of processed food will within a matter of minutes puff up to a multiple of their size, and when stirred will simply break up into a liquid solution. Natural (unprocessed, even minimally processed) foods will generally stay together for a lot longer.

      That's not exactly a surprising observation. Same thing is true of most particleboard vs. unprocessed wood as well. You've failed to demonstrate at all why this would be a problem. Try your test on some chicken flesh compared to an identical piece of chicken flesh that's been chewed, swallowed, then chemically processed by enzymes and stomach acids in a human stomach. After you've tried that test, you may understand why your argument is easily dismissed by most people when you put it that way.

      That said, there are reasons more heavily processed foods may be worse for you than unprocessed. One of those reasons is that the processed foods often simply come from poorer base materials than the unprocessed foods, which is why they needed to be processed in the first place. If the unprocessed food is a nice cut of chicken breast and the processed food is ground up chicken cartilage with a little bone and other otherwise less than usable bits of the chicken after everything is else is stripped off, then the processed food typically won't be as good. That's not universally true though. The hydroxyl-apatite in ground bone can actually be an ideal source of bio-available calcium, for example, and various organ meats which people typically shun in low-processed form are full of great nutrition. The majority of what goes into the processed chicken patty, however, is crap. Figuratively and also, to some degree, literally. Processes get developed to extract the maximum nutrition from food. This should be a good thing in a hungry world. Unfortunately, it's a hungry world with marketing departments and a heavy profit motive.

      Processing of food isn't inherently evil. People have been processing food to extract more nutrition from it for millennia. Grinding bones to make your bread (bone cakes are full of calcium and nutritious bone marrow) is just one example. Another set of great examples are demonstrated by Pellagra and Kwashiorkor which are two medical conditions. You may not have heard of Pellagra, but just think of a typical portrayal of leprosy and you won't go far wrong. Kwashiorkor you have probably seen in ads for hunger-relief charities: swollen ankles, distended belly, hair loss, loss of teeth, dermatitis. These conditions are specialized forms of malnutrition that can occur in individuals who may actually be getting enough food to survive (although they may frequently be generally malnourished as well), but are suffering from niacin or protein deficiencies. They both tend to show up among people who live essentially exclusively on corn (poor Italian peasants in the case of Pellagra, and mostly African children living on food aid for Kwashiorkor). The all-corn diet might be providing enough calories, but is deficient in some vital nutrients. As it turns out, South American natives living on the same diet weren't suffering from these same issues. The reason comes down to food processing. Traditional preparation of corn involves nixtamalizing it, which basically means boiling it in a lime (the mineral, not the fruit) solution. The resulting processed food, called nixtamal is more nutritious (technically, it has fewer calories, but it provides a wider variety of nutrients) and people using it as a staple food are less likely to develop extreme nutritional disorders.

      Going back to the downsides of processing food, there's the issue of preservation. Some processing, of course, preserves much of the nutritive value of the food for a very long time. Examples of this are salting, dehydrating and pickling. The processing does, however, often destroy some of the nutrients in the food as well and it typically involves p
