Air pressure can have effects on chemical processes, at least when some kind of phase transition may occur between liquid and gaseous phases. I don't think that's happening here, but the vacuum could have some negligible effect on, say, drying out the meat (evaporation is faster at lower pressures)
- thomasfedb 3y agoIf we want to be particularly pedantic (and apparently I do)… the process you mention - evaporation - is better classified as a physical process (inter-molecular forces) rather than a chemical process (molecular bonds).
- xvedejas 3y agoAh yeah, I didn't mean evaporation was a chemical process, it was something in addition to that. Aside from evaporation, there are chemical processes which (for example) generate gases, which is not a phase change but a change to form a different molecule that is gaseous at the given conditions. The cool thing is that the rate of such reactions is usually dependent on the pressure.
