How can fruits and vegetables generally be preserved to maintain freshness?

Refrigerating fruits and vegetables is one of the most effective methods for preserving their freshness. This process slows down the respiration rate of the produce, helping to maintain their texture, flavor, and nutritional value over time. Cooler temperatures inhibit the growth of mold and bacteria, which can cause spoilage.

Most fruits and vegetables benefit from being stored in a refrigerator, as the cold environment can significantly prolong their shelf life. For example, leafy greens like spinach and herbs retain their crispness in the fridge, while berries and other fruits slow down ripening and potential spoilage.

In contrast, exposing fruits and vegetables to air can lead to oxidation, which may result in browning and loss of flavor. Cooking can alter the nutritional content and texture of fresh produce, often reducing vitamins. Leaving them at room temperature can accelerate spoilage, especially for items that are highly perishable. Thus, refrigeration is the best practice for maintaining the freshness of fruits and vegetables.
