Watermelon is one of the most refreshing and hydrating fruits, perfect for hot summer days. However, once cut, its shelf life significantly decreases. If you’re wondering how long watermelon lasts after being cut in half, you’re not alone. In this article, we’ll delve into the factors that affect the shelf life of cut watermelon, provide tips on how to store it, and explore ways to extend its freshness.
Factors Affecting the Shelf Life of Cut Watermelon
Several factors contribute to the degradation of cut watermelon, including:
Exposure to Air
When watermelon is cut, the cells are broken, releasing enzymes that cause the fruit to spoil faster. Exposure to air accelerates this process, as oxygen reacts with the enzymes, leading to a loss of texture, flavor, and color.
Temperature
Temperature plays a crucial role in the shelf life of cut watermelon. At room temperature (around 70°F to 75°F or 21°C to 24°C), cut watermelon will typically last for 2 to 3 days. However, if stored in the refrigerator at a consistent temperature below 40°F (4°C), it can last for 5 to 7 days.
Humidity
High humidity can cause cut watermelon to spoil faster, as it creates an ideal environment for bacterial growth. On the other hand, low humidity can cause the fruit to dry out, leading to a loss of flavor and texture.
Handling and Storage
Improper handling and storage can significantly reduce the shelf life of cut watermelon. If not stored in a sealed container or wrapped tightly in plastic wrap, the fruit can absorb odors and flavors from other foods, leading to spoilage.
How to Store Cut Watermelon
To extend the shelf life of cut watermelon, follow these storage tips:
Refrigerate Immediately
After cutting the watermelon, refrigerate it immediately to slow down the spoilage process. Make sure to store it in a sealed container or wrap it tightly in plastic wrap to prevent moisture and other contaminants from entering.
Keep it Away from Strong-Smelling Foods
Cut watermelon can absorb odors and flavors from other foods, so it’s essential to store it away from strong-smelling foods like onions, garlic, and fish.
Use a Clean and Dry Container
Before storing cut watermelon, ensure the container is clean and dry. Any residual moisture or bacteria can cause the fruit to spoil faster.
Monitor Temperature and Humidity
Keep an eye on the temperature and humidity levels in your refrigerator to ensure they remain consistent. A temperature range of 39°F to 41°F (4°C to 5°C) and a relative humidity of 80% to 90% are ideal for storing cut watermelon.
How Long Does Cut Watermelon Last?
The shelf life of cut watermelon depends on various factors, including storage conditions, handling, and personal preferences. Generally, cut watermelon can last for:

How long does watermelon last after being cut in half?
Watermelon typically lasts for 3 to 5 days after being cut in half, depending on various factors such as storage conditions, handling, and the ripeness of the fruit when it was cut. If stored properly in the refrigerator at a temperature of 40°F (4°C) or below, cut watermelon can retain its freshness and flavor for several days.
However, it’s essential to note that cut watermelon is more prone to spoilage than a whole watermelon due to the increased exposure to air, bacteria, and other contaminants. To maximize its shelf life, it’s crucial to store the cut watermelon in a sealed container, cover it with plastic wrap or aluminum foil, and keep it away from strong-smelling foods, as watermelon can absorb odors easily.
What factors affect the shelf life of cut watermelon?
Several factors can impact the shelf life of cut watermelon, including the ripeness of the fruit when it was cut, storage conditions, handling, and personal hygiene. If the watermelon was not ripe when it was cut, it may not last as long as a ripe one. Similarly, if the cut watermelon is not stored properly in the refrigerator or is exposed to warm temperatures, it can spoil faster.
Additionally, handling the cut watermelon with dirty hands or utensils can introduce bacteria and other contaminants, reducing its shelf life. It’s also important to note that cut watermelon can be affected by cross-contamination from other foods, so it’s essential to store it separately and keep it away from strong-smelling foods.
How should I store cut watermelon to maximize its shelf life?
