    Heating causes evaporation even if boiling isn’t technically achieved.

    Like how salt pools will evaporate out water despite the earth not constantly being at 100° C.

        No, but pasteurization technically is done with an open top container

        And, yeah that is technically correct, hence it being in showerthoughts

      Let me introduce you to the concept of vapor pressure. The volatility of a material depends on the temperature. Even cold water will still evaporate slowly. Instead is being a binary things, the vapor pressure will increase gradually as the temperature increases.

      This means, that you can empty a glass of water by just waiting. You don’t even need to boil the water to make it evaporate. It’s already evaporating very slowly, even in room temperature.

      Therefore, raw milk straight from the udder, is also evaporated milk.
