The eggplants are consumed when young and never used after ripening, whereas tomatoes are used after ripening. The peppers can be used before or after ripening depending on the type. Potato is the exception in this family, and the edible part is the stem tuber. Solanaceous fruits do not store very well. In general, a postharvest life of 7–10 days can be anticipated during refrigerated storage. Potatoes, on the other hand, can be stored for months covered with dry soil in a cool place or under a controlled atmosphere at a low temperature.
