You are correct about the amount of capsaicin in the air. Frying will cause the chiles to off-gas. I've dumped the firehouse on a couple of occasions (enui) doing this. This is one way to reduce the heat of chiles and still enjoy their flavor. Obviously, any cap in the air means that much less in the dish. Hard to convince co-workers that the stuff is tame after it has driven them to do a low crawl out of the house :-) But then, I don't try too hard as it keeps them out of my stuff ;-) -Jim C MWPH
