37. High Heat Destroys It Anyway

Mon Apr 13, 2020, 04:01 PM

Apr 2020

The lipid layer is a couple hundred nanometers thick.
It does not provide protection from heat. The thermal conductivity of lipids is reasonably high. Not like water, but not terrible. It does have a pretty high heat capacity or an organic compound.
So, ironing would work.
However, presuming the iron is around 100C, that level of heat would take 2 minutes (time required at 60C) divided by 16. Or 7.5 seconds.
I can see people thinking a couple seconds would be enough.

Ahhh. I thought heat, like an autoclave, would also kill the virus Siwsan Apr 2020 #3

The soap breaks down the protective fat layer surrounding the virus protein TeamPooka Apr 2020 #5

This virus is digested in the stomach after eating it. uppityperson Apr 2020 #29

I have a food steamer that I use to reheat food rather than use the microwave kimbutgar Apr 2020 #23
