I stopped in Union Square in New York City on a Saturday morning and found apples. These were not fresh picked. These have been refrigerated and packed in a controlled atmosphere cold, humid, nitrogen rich and low in CO2.
This is not new. a century ago clever orchard keepers packed their ice house with sacks of lime. The lime oxidized into Calcium carbonate stripping the air of CO2 in the process.
I ate many and while not at their peak, many were quite good. Except the Lady Apples. Those are terrible even fresh, strictly decorative.
