From Twinkie, Deconstructed by Steve Ettlinger (via body+soul magazine):
Ethylene oxide [part of Polysorbate 60, a Twinkie ingredient] is an excellent but entirely unlikely food chemical, seeing as it is highly explosive (it was used in tunnel-busting shells during the Vietnam War), a known human carcinogen, and a respiratory, skin, and eye irritant.

A little knowledge is a dangerous thing. I’m apalled and astounded at how little I know about the food that’s been going into my body for the last 25 years. Do you know what goes into a chicken McNugget? A plethora of ingredients, most of which are NOT chicken.
And do you know that they spray butane (or a form of butane, anyway) on the nuggets and/or box for freshness? As little as a gram of this stuff can kill you, but they spray it on the faux chicken bits so they don’t go off.
I think E. coli is the least of our worries when eating at fast food restaurants.
Becoming. Beautiful. Healing from binge eating disorder. 
“A little knowledge is a dangerous thing. ”
Oh, the irony. Ethylene Oxide has about as much to do with Polysorbate 60 as Table Salt does with hydrochloric acid. i.e., nothing.
They might have a few atoms in common but that means nothing at all.
The same is true of your “butane” in McNuggets. That’s another piece of chemical illiteracy that’s propagated from liberal to liberal like it’s gospel. It’s bullshit. The preservative they use is an antioxidant that has nothing to do with butane.
Can you give me some references or some more facts instead of merely calling these things bullshit? I’m admitting my own ignorance on this blog daily, and if you have some additional information for me, I am happy to consider it.
But merely calling these ideas, which I am citing from reputable sources, bullshit is less than helpful.
