Green Beans

Green beans are highly susceptible to moisture, and placing them in a cold environment like the refrigerator can cause them to become soft and lose their appealing crispness. Additionally, green beans are sensitive to ethylene gas, which is naturally produced by many fruits and vegetables when they ripen.
When stored together with fruits that release ethylene gas, such as apples or bananas, green beans can quickly wilt and develop an off taste. Instead of refrigerating green beans, it is best to keep them at room temperature for optimal preservation.
