Decomposition of tryglicerides/glycerol into Acrolein?

I'm a bit confused on this one, according to literature, Acrolein is formed at temperatures above 280° C, but has an autoignition temperature below that.

So, how can it be formed by cooking oil getting too hot, without burning up immediately?

Assuming the data on that is correct, does that mean there's some kind of catalyst in the oil itself?

If there is no oxygen things will not ignite. Its in an atmosphere of acrolein, glycerol, steam or other decomposition products.

Okay...I assumed the vapour would be sufficiently dispersed to mix and react with the oxygen, so I guess it's already cooled below ignition temperature before that can happen?
