Engineering Food at the Molecular Level
Krishna Dagli writes to mention a New York Times article about the possibility of manipulating food at a molecular level. Though some of the initial suggestions are a little pointless (lower-fat ice cream, harder-to-melt M&Ms), weighter goals could eventually be achieved here as well. From the article: "Given the uncertainty about the risks of consuming new nano products, many analysts expect near-term investment to focus on novel food processing and packaging technology. That is the niche targeted by Sunny Oh, whose start-up company, OilFresh, based in Sunnyvale, Calif., is marketing a novel device to keep frying oil fresh. OilFresh grinds zeolite, a mineral, into tiny beads averaging 20 nanometers across and coats them with an undisclosed material. Packed into a shelf inside the fryer, the beads interfere with chemical processes that break down the oil or form hydrocarbon clusters, Mr. Oh says. As a result, restaurants can use oil longer and transfer heat to food at lower temperatures, although they still need traditional filters to remove food waste from the oil. Mr. Oh said OilFresh will move beyond restaurants into food processing by the end of the month, when it delivers a 1,000-ton version of the device to a 'midsized potato chip company' that he said did not want to be identified. "
when interfering with natural food processes like this. Are you doing mankind a favour or creating a stream of cancer patients 20 years down the line.
Artificial preservatives and flavourings were the bees knees apprently when they hit the shelves first until it turned out many were carcinogens or just really not what you body wanted to be accumulating. Now look at the consumer demand for organically grown and prepared food.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
May cause Anal Leakage. WTF?

Essentially (yes, I did not RTFA) we are talking about injecting nano-particles into the frying oil to make it last longer?
Even though some nano-materials could be highly dangerous to human health? In other words, we may end up with highly dangerous cancer-causing products used in kitchens? To fry greasy stuff that we know are bad for our health anyway? Talk about a double whammy: if your heart attack does not kill you, cancer from nano-particles will. And do you want fries with that?
Then again, this is business as usual in the USA, so I guess it will probably be used soon.

Wouldn't it be better to grow food instead of engineer food? Moore's Law doesn't have to apply to everything.
because the long term effects of synthetic food are not clear and because the companies promoting the stuff are - how to say this diplomatically - less than forthcoming with the downsides, side effects and seem not to understand the meaning of the word 'disclosure'.
I'm all for progress, but food is delicate, mistakes have often serious and sometimes fatal effects. It doesn't take a lot of imagination to see that in todays environment a short term financial gain for a corporation will outweigh a long term health risk. Until that trend reverses I'm all for caution.

In what sense is food 'delicate'? Certainly an industrial product can be toxic, but food is not an exceptional case. In fact, we should expect our bodies to be more tolerant of food and water pollution than of other vectors. After all, you've got a million years of evolution behind you, ensuring that your gullet can tolerate the half-rotted carcass you found lying on the jungle floor.
I'd bet that 99.99% of food-related fatalities over the past 30 years have been due to natural pathogens (or choking). Care for some organic spinach?
FATMOUSE + YOU = FATMOUSE
my body has through it's evolutionary predecessors had a lot of time to adjust to the stuff that grows on and walks on the fields. 'new' foodstuffs introduced without very rigid testing procedures which will cost lots of $ and will take lots of time from secretive corporations have the potential to do a great deal of harm.
Being educated not only implies that you are for progress, it also implies that you recognize when to be cautious and what you can do to assess the risks that others are exposing you to.
Unhealthy biological foods are a risk, badly engineered foods pose a possible much larger risk and those risks need to be weighed carefully. If the companies that feed you this (chips factory does not want to be named ?? why not, it's progress, so it's good right ?) stuff do not want to come clean about it then my immediate question is what are they hiding and what is the long term effect of this stuff in quantity.
In lab tests it has more or less been demonstrated that anything in large enough quantities will give you cancer, be it peanut butter or radioactive milk. (yes, all milk is very slightly radioactive), so that apparently is just a question of dosage.
The questions with new stuff are very simple:
- what goes in it ?
- how was it tested ?
(preferably a double-blind test like used on new medication)
- and assuming it was tested can we please see the results ?
- what are the upsides (other than some marginal expense savings on the part of the
operator of a restaurant or factory), is it healthier than whatever it replaces ?
- what are the downsides short term and long term ?
(think of allergic reactions and such for short term and cancer & the like long term)
Companies that mess with staple foods behind closed doors bear close watching.
Think about it, if McD would adopt this stuff and it turned out that there is this
small problem that 10 years down the line you drop dead then we're going to have
a little problem. I concede that's an extreme example but if they won't even tell
you who is using it then it gets a little harder to believe they're upfront about
the rest.

Food poses a larger threat because we expect interact with it so closely. There are plenty of toxic chemicals around the house, but for the most part we don't expect to place them directly into our bodies.
But none of those million years were we exposed to some of the chemicals/proteins/etc that are being geneticly engineered into foods. Although I think the outrage of some against bioengineered food is unjustified, there are definately risks that need to be thoroughly evaluated.

It's not like food has been statically unchanged over the last several thousand years, or even several hundred years. We've been using selective breeding techniques ever since we started agriculture. Do you think that chicken you're eating is like the original un-domesticated version that came from the wild? Is the corn, wheat, tomatoes, etc the same as it was 2000 years ago, or even 200 years ago?
Rejecting GM, processed, or whatever food with broad strokes doesn't make any sense. We've been changing our food for a long long time, so you really shouldn't be eating anything that society (modern or non-modern) produces at all. If you want "purity before human intervention" you should go back to the hunter-gatherer society, just be carefull not to gather anything that's reproduced with human-interferred stuff.
That's not to say that you shouldn't be concerned with food additives, GM foods, etc. It's just a matter of making sure it's all safe rather than rejecting it all out of hand.

And industrial production of food occurred for how many of those million years of evolution?
Not everything else improves. Music CD technology came out and eventually killed dynamic range. Digital cable came out and we lost the ability to flip quickly through channels. Wide screen TV's came out and now everyone watches their favorite shows with all the actors' faces all stretched.
In medicine, you can say we've made progress, but now we have doctors over-recommending surgery for basic conditions. And psychiatrists prescribing Paxil and SSRI's to anyone who feels a little stressed.
This may be the worst thing I've ever read on Slashdot. Nature is the least efficient way of making food? Look at the way a seed turns into a plant which gives us fruit. Or look at how any animal comes into being. A damn egg turns into a live chicken. Nature does all of these things without following a single blueprint. And you call it inefficient?
