1. Why is it a big taboo to put watermelon directly in the refrigerator?

Many people think that putting watermelon in the refrigerator can extend its freshness and maintain its taste. However, experienced farmers shake their heads: "Watermelon is not as simple as you think!" Here are several major drawbacks of directly putting watermelon in the refrigerator:

1. Low temperature destroys taste

Watermelon is a typical tropical fruit, and the suitable storage temperature is between 10-15℃. If placed directly in the refrigerator (usually at 2-5℃), the low temperature will damage the cell structure of the watermelon, causing the flesh to become mushy and lose its original crispness. This is especially true for high-quality thin-skinned watermelons, as low temperatures can more easily cause the flesh to "leak water," making it taste like chewing on cotton.

2. Loss of flavor

The sweet flavor of watermelon comes from the sugars and aromatic substances in the flesh. The low temperature in the refrigerator slows down the metabolism of these substances, but it also inhibits the release of aroma and can even cause the watermelon to absorb odors from the refrigerator, such as garlic or onion. Imagine biting into a watermelon that tastes like green onions; that wouldn't be pleasant!

3. Easy to breed bacteria

Many people do not wash the watermelon after buying it and just throw it into the refrigerator. The surface of the watermelon may carry dirt, bacteria, or pesticide residues, which can more easily breed mold in the humid environment of the refrigerator. Especially for cut watermelons, if not properly wrapped, bacteria can quickly multiply, leading to spoilage of the flesh.

4. Waste of refrigerator space

A whole watermelon is large and takes up a lot of space in the refrigerator. If stored improperly, such as stacking carelessly, it may crush other ingredients, making it not worth the trouble.

The experienced farmer smiles and says, "Watermelon is a 'delicate' fruit; you need to learn its temperament to keep that sweetness." Next, we will reveal the storage secrets of the experienced farmer, which are simple and practical, ensuring you can enjoy sweet and juicy watermelon!

2. The experienced farmer's storage secrets: Fresh and sweet for a week

The storage methods of the experienced farmer are divided into two situations: whole watermelon and cut watermelon. In either case, the watermelon can be kept in the best condition. Here are the detailed steps:

(1) Storage method for whole watermelon

1. Choosing the right watermelon is key

The first step in storage starts with selecting the watermelon. The experienced farmer teaches you "three looks and one knock":

Look at the skin: Watermelons with smooth skin, clear stripes, and bright colors are usually healthier and more durable.

Look at the stem: A slightly curled and slightly yellow stem indicates the watermelon is at the right ripeness; if the stem is too green, it may not be fully ripe.

Look at the bottom circle: The smaller the yellow circle at the bottom of the watermelon, the sweeter the fruit, and it is less likely to spoil during storage.

Knock on it: Gently knock on the watermelon with your finger; if it produces a crisp sound with a slight "buzz," it usually means the flesh is firm and suitable for storage.

2. Cleaning and drying

After buying the watermelon, first rinse the surface with clean water to remove dirt and bacteria. For stubborn stains, you can gently scrub with a soft brush. After washing, dry the skin with a clean, dry cloth to prevent moisture from causing mold. Remember not to use detergent to avoid chemical substances seeping into the flesh.

3. Store in a cool, ventilated place

A whole watermelon does not need to be placed in the refrigerator! The experienced farmer's secret is to place it in a cool, ventilated area, such as a corner of the balcony or under the kitchen cabinet, with the best temperature maintained at 10-15℃. You can use a clean straw mat or wooden board underneath to avoid direct contact with the ground.

• Avoid direct sunlight: Sunlight accelerates fermentation inside the watermelon, causing the flesh to become sour.
• Avoid stacking: Do not place the watermelon with other fruits (like apples or bananas), as the ethylene released by these fruits will accelerate the ripening of the watermelon, shortening the storage time.

4. Regularly turn the watermelon

Every 2-3 days, gently turn the watermelon to prevent one side from being pressed for too long, which can cause deformation or rot of the flesh. While turning, check if the skin has softened or has any off odors, and address any problematic watermelons in a timely manner.

Storage effect: By following this method, a whole watermelon can be stored for 7-10 days, maintaining its sweet taste and firm flesh. Even in the hot summer, it can retain excellent flavor for 5-7 days.

(2) Storage method for cut watermelon

Cut watermelon is more prone to spoilage, but as long as you master the following techniques, it can still be stored well!

1. Quickly handle the cut surface

When cutting watermelon, try to use clean knives and cutting boards to avoid cross-contamination. After cutting, immediately wrap the cut surface tightly with clean plastic wrap to prevent air from entering and moisture from escaping. Make sure there are no gaps when wrapping, and it's best to wrap it in several layers.

2. Store in portions

If you can't finish the cut watermelon, it's recommended to divide the flesh into small portions, each stored in a fresh-keeping box or sealed bag. This makes it convenient to take out and reduces air exposure, lowering the risk of spoilage. Before packing, you can gently absorb excess juice from the surface with a clean kitchen towel to keep the flesh dry.

3. Refrigerate but do not overdo it

Cut watermelon needs to be refrigerated, but the temperature should not be too low; it is recommended to place it in the vegetable and fruit compartment of the refrigerator (about 5-8℃). Do not put the watermelon in the freezer, or the flesh will become icy and ruin the texture.

Storage position: Place the watermelon towards the back of the refrigerator to avoid temperature fluctuations caused by frequently opening and closing the door.

Time control: It is best to eat cut watermelon within 3-5 days; even if stored properly, the flavor may decline after a week.

4. Clever use of natural preservatives

The experienced farmer has a unique secret: before wrapping the watermelon, you can apply a thin layer of honey or lemon juice to the cut surface. These two natural substances have antibacterial properties and can effectively slow down the oxidation of the flesh, maintaining its sweet taste. When applying, use a clean brush and apply a thin layer; too much will affect the flavor.

Storage effect: If cut watermelon is stored using this method, it will still be juicy and sweet within 3-5 days, with the flesh remaining crisp and the flavor hardly diminished. If treated with honey or lemon juice, it can even last up to 7 days.

3. Common misconceptions and tips

During the process of storing watermelon, many people tend to make some mistakes.

• Do not put watermelon directly in a plastic bag

Plastic bags have poor sealing and can easily accumulate moisture, leading to mold on the surface of the watermelon. If you need to use a plastic bag, it is recommended to wrap it in plastic wrap first, then place it in the bag.
