answer:To answer your question, this link has a list of ethylene producing and ethylene sensitive fruits and veggies. The ethylene gas is what causes fruits and veg to ripen and eventually become rotten. I keep pretty much all vegetables in the fridge. Some fruits I leave on the counter for a a day or so if they need to ripen a little more, but eventually it all winds up in the fridgeif I have not eaten it in a day or so. Some fruits don’t do well in the fridge if they are in there for a long time, changing the fruits texture or flavor, but things like apples and citrus do very well, I put both in the fridge straight away. I even keep my bananas in the fridge once they get just past green, because I hate them overripe. Do you live in a cool climate that it is customary to leave produce out rather than refridgerated?
