Ripening fruit in bagsYes. It can help to hasten the ripening process of some fruit if you place them in a paper bag. Ripening fruit release ethylene gas, and exposure to ethylene has been shown to hasten ripening, so placing the fruit in a closed bag traps the ethylene and facilitates ripening. This only works for fruit that ripen after being harvested. Apples, pears, peaches, plums, and bananas, to name a few, will benefit from being placed in a bag.
