That's not how condensation works. In short, warm air has a higher carrying capacity for moisture, lower the temperature of air and the relative humidity of that air will rise until it surpasses it's carrying capacity and leaves the air as condensation. Ergo, warm air will condesate on a cold surface, such as a window pane, beer can, etc.
The inside of a sealed can will not condesate just because there's warmer or colder air outside of the can....now if there's a way for moisture to get into the canister the powder will obviously get wet, but not from condensation.
Now if you take jar of room temperature air, containing some moisture, say 40% humidity, and put it in the freezer, yes, the air in that jar will cool and thereby force the moisture in that air out as condensation.
