Tomatoes should not be stored in plastic bags because they trap moisture, accelerating spoilage and promoting mold growth. Storing them in a breathable container or on the counter is preferable.
Tomatoes are sensitive to their environment, and proper storage is crucial for maintaining their flavor and texture. Plastic bags create a humid environment around the tomatoes. This trapped moisture encourages the growth of mold and bacteria, leading to faster decomposition. Furthermore, tomatoes release ethylene gas as they ripen, which accelerates the ripening process. In a confined space like a plastic bag, the concentration of ethylene gas increases, causing the tomatoes to overripen and spoil more quickly. Ideally, tomatoes should be stored at room temperature, away from direct sunlight, in a single layer, and in a breathable container or simply on the counter. This allows for proper air circulation, preventing moisture buildup and slowing down the ripening process. If your tomatoes are already ripe, you can store them in the refrigerator to extend their shelf life, but be aware that this can affect their texture and flavor.
If you must refrigerate tomatoes, let them come to room temperature before eating to help restore some of their flavor. The cold temperature can diminish their taste.
