Thanks for the link, Dave.IF
I read this right (after flunking college chem once and dropping it before I flunked it the second time
), the main products produced are carbon monoxide (not too good for breathing, but ingesting?), carbon dioxide (have a Coke, anyone?), and water. Some concern of formaldehyde, but nothing firm. Somebody please speak up if you read it differently. Chemistry isn't my thing.
The kicker for me is the last sentence: "however, sensory irritation is lower than that produced by wood
". Don't we smoke with wood? I assume this refers to breathing the fumes. If so, it seems like the question is whether any particles in the fumes are deposited on the food, and if ingesting those particles is harmful. You got me...
I still lean towards the idea that we are sressing way too much over these liners. Some time in the last couple of weeks I have read a post (not sure which forum) about a company making UDSs out of food-grade barrels, with the liners intact. I'll see if I can find that quote and dig into the company some.
Thanks again for the link, and if anybody reads the info differently, please speak up. Like I said, chemistry is definitely not my strong point.
