What is one effective way to prolong the shelf life of fruits and vegetables?

Storing fruits and vegetables in cool, dry conditions is effective in prolonging their shelf life because it helps to slow down the natural processes of decay and spoilage. Cool temperatures reduce the metabolic rate of the produce, which delays ripening and prevents spoilage. Dry conditions further minimize the growth of mold and bacteria, which thrive in moist environments. This method of storage maintains the freshness and nutritional quality of fruits and vegetables for a longer period, thus extending their usability.

The other options, such as leaving produce at room temperature or exposing it to sunlight, can accelerate ripening and spoilage due to increased temperatures and exposure to light, leading to faster deterioration. Washing fruits and vegetables after purchasing is important for food safety but does not specifically prolong their shelf life unless they are dried properly before storage; otherwise, moisture can lead to spoilage.
