How to store watermelon in summer, can it be stored and not spoiled?

Here are a few ways to store watermelon that can be kept safe and not easy to spoil:

1.Put it in the freezer:Refrigerate the watermelon in the refrigerator, keep it at a temperature of 4-5, and wrap it in plastic wrap or a plastic bag to extend the shelf life of the watermelon.

2.Cool and ventilated place:Keep it in a ventilated, shaded place away from direct sunlight to keep the watermelon fresh.

3.Do not wash with water:Do not wash the watermelon with water before storage, otherwise it will facilitate the reproduction of bacteria and accelerate the decay.

4.Keep in a dry place:Choose a dry place for storage to avoid mildew caused by moisture.

5.Cut it open and put it in the refrigerator:If the watermelon has already been cut, you can put the rest in the refrigerator and wrap it in plastic wrap or a plastic bag to extend the shelf life.

In addition, if you like to eat watermelon, take a look at this selection method:

How to pick watermelon in summer:

1.Appearance: Watermelon should have a clear bright green color**, with no scratches or weak spots. There should be a crisp sound when percussion.

2.Size: Choose a watermelon that fits the size of your family.

3.Weight: Pick a relatively heavy watermelon. The heavier the weight, the more moisture the melon has.

4.Top: The top should be smooth, with no protruding or collapsing sections.

5.Bottom: There should be a yellowish spot on the bottom, which means that the melon is ripe and has been picked from the ground.

6.Feel: Feel the surface and color of the watermelon. Choose a melon peel that is smooth but not rough, and a pale green watermelon.

7.Smell: Smell the watermelon, if it spits out a sweet smell, it means that the melon is very fresh.

Notes:

1.Washing: Before eating watermelon, be sure to remove the sediment, uncleanliness and other debris on the surface.

3.Avoid overdose: Although watermelon is a good hydrating food, eating too much can increase the burden on the stomach and calorie intake.

4.Avoid eating rotten watermelon: When buying watermelon, pay attention to its appearance and choose watermelon that is not cracked, rotten, shiny, and dry.

5.Avoid watermelons that are too big: Watermelons that are too big can become watery and cause indigestion.

6.Don't eat too quickly: Don't eat too much watermelon in one sitting, you should eat it in portions and enjoy it slowly.

7.Avoid eating melon seeds: melon seeds have a high fat content, which is easy to cause acne and sores in summer, so you should eat less or no food.

8.Avoid eating it with other foods: Watermelon and other fresh foods can cause gastrointestinal upset and should be eaten on its own.

Method 1: Choose a high-quality watermelon with intact skin and moderate size, wipe the skin with a dry cloth first, and then soak it in salt water with a concentration of 15-20% for about half an hour. Take it out and put it in a ventilated place, after the water on the skin evaporates naturally, seal the watermelon in a clean food bag and store it in a cool and ventilated place for 1-2 months.

Method 2: If the cut watermelon can't be eaten, you can wrap the watermelon in plastic wrap and put it in the refrigerator, so that the watermelon can be stored for 1-2 days.

If the watermelon is not cut, just put it directly in a cool and ventilated place, and it is generally no problem to store it for three to five days; If the watermelon has been cut, wrap it in plastic wrap and put it in the refrigerator, where it can generally be stored for two or three days.

The storage of summer watermelon is key to ensuring that it stays fresh and does not spoil. Here are some ways to store your watermelon to keep it in good shape:

1.Temperature: Watermelons spoil easily at lower temperatures, but they should not be exposed to excessively high temperatures.

The best storage temperature is 10-15 degrees Celsius. You can store watermelon indoors in a cool place, or put it in the fruit and vegetable compartment of the refrigerator (preferably without direct contact with other foods).

2.Humidity: Watermelons prefer relatively high humidity. You can place a damp cloth or damp paper towel around your watermelon to help maintain moderate humidity. Also, make sure that the storage environment is not too dry to prevent the surface of the watermelon from dehydrating too quickly.

3.Ventilation: When storing watermelons, make sure there is adequate ventilation. This can be achieved by avoiding stacking watermelons together or placing them in airtight containers. Proper ventilation helps prevent mold growth and secondary spoilage.

4.Avoid damage: Avoid applying pressure or damage to the watermelon during storage to prevent it from spoiling. Try to avoid falling or coming into contact with other hard objects.

5.Inspection and turning: Regularly inspect stored watermelons and remove any parts that appear to be broken, softened, or rotten. The watermelon can also be gently turned to ensure that the different parts of the watermelon are evenly circulated and pressured by air.

It is important to note that watermelons that have been cut should be eaten as soon as possible, as the longer it is exposed to the environment, the faster its quality will deteriorate. It is best to keep the cut watermelon in the refrigerator before drinking it and consume it in a short time.

In summary, proper temperature, humidity, and ventilation are key to keeping summer watermelons fresh. Following these storage methods can extend the shelf life of watermelon and maintain its best quality.

When storing watermelon, it is best to attach a layer of plastic wrap to the cut surface before putting it in the refrigerator. When eating, remove the plastic wrap and use a kitchen knife to cut off the top layer before eating. This removes some of the bacteria that have grown.

The freezing time in the refrigerator should not be too long, it is best not to exceed a day, it is easy to deteriorate after a long time, and it is easy to have diarrhea after eating.

Due to the hot weather in summer, watermelons that cannot be eaten will definitely spoil easily. So cut the leftover watermelon and wrap it in plastic wrap and store it in the freezer compartment of the refrigerator. If there is a drawer in the refrigerator for vegetable preservation, put it in that and you can store it for an extra day or two.

If the watermelon is too big, it must be in the refrigerator.

Especially the cut watermelon, it is really easy to spoil when you put it outside, so you need to close the cut hole with plastic wrap and put it in the refrigerator.

But to be honest, even if you put it in the refrigerator, you can't eat it for too long, at most you have to eat it every other day, otherwise it will affect the taste.

Before cutting the watermelon, clean the surface, knife and cutting board of the watermelon.

2.Seal the cut watermelon with plastic wrap as soon as possible and put it in the refrigerator.

After the watermelon is cut, the longer the flesh is exposed to the air, the more bacteria are contaminated on its surface.

3.It is best not to store watermelon in the refrigerator for more than 12 hours.

Refrigerators are not "safes" and can harbor bacteria even at low temperatures. After experimentation, the longer it is placed in the refrigerator, the more bacteria the watermelon has. Plastic wrap is not a panacea, although it can keep the watermelon hydrated to a certain extent and prevent cross-infection, but there will also be a small amount of air entering and carrying bacteria.

Therefore, it is best not to keep watermelon in the refrigerator for more than 12 hours and not more than 24 hours at most.

Cover the surface of the cut watermelon with plastic wrap and put it in the refrigerator. When eating, remove the plastic wrap and cut off the top layer with a kitchen knife, and then eat again. The freezing time in the refrigerator should not be too long, and it is best not to leave it for more than a day, which is easy to deteriorate.

In summer, everyone likes to put watermelon in the refrigerator and eat it chilled, but in fact, the nutrients rich in watermelon after chilling are far lower than watermelon stored at room temperature. According to research, watermelons can still produce nutrients after being picked, but rapid cooling will delay the process of nutrient production, thereby reducing the nutrient content.

Normally, watermelon can be stored for 14 to 21 days under 13 shelf life; But if it's chilled, say only 5, the watermelon will start to rot after a week. Watermelon is best kept at room temperature, as it contains 40% more lycopene and 139% more carotene than chilled watermelon, which are components of antioxidants that have antioxidant properties. The fresher the summer fruits and vegetables, the better the nutrition, and the least impact on the human body.

Do not store newly bought watermelons in the refrigerator for more than a day, and store them for no more than an hour after cutting. The refrigerator contains anaerobic bacteria, and with the extension of time, the number of anaerobic bacteria will increase, attached to the cut watermelon pulp, which will not only destroy the vitamins, minerals and other nutrients contained in the watermelon, but also may make people with good gastrointestinal function have gastrointestinal disorders, diarrhea and other symptoms. In addition, watermelon is a fruit with a high water content, and long-term refrigeration will cause a large amount of water to evaporate and take away nutrients.

1. You only need plastic wrap, or a supermarket food bag, and then prepare a basin of cold water.

2. Wrap the watermelon in plastic wrap, and then use a toothpick to make some small holes in the plastic wrap.

3. Slowly put the wrapped watermelon into cold water (note: the water cannot exceed the surface of the watermelon), and it is not a problem to put it for two days, which is similar to the principle of putting it in the cellar.

When you want to eat it again, cut off the top layer of the watermelon first, so that the taste will be better. However, it is recommended that watermelon is still freshly cut and eaten; If you keep it in the refrigerator, it is best not to exceed 24 hours.

Watermelon is refreshing and thirst-quenching is a good fruit in midsummer, which can be called the "king of melons". The rumor that watermelon wrapped in plastic wrap will multiply bacteria is always widely spread in summer. Many netizens even said that "I don't need plastic wrap anymore".

Watermelon + plastic wrap = raising bacteria?

In fact, watermelons covered with plastic wrap may have been contaminated before putting them in the refrigerator. The rate at which bacteria multiply depends on the degree of contamination of the food and the environment in which the food is stored.

Watermelons covered in plastic wrap are prone to bacterial growth, and this cannot be seen as a problem with plastic wrap alone. Because the knife for cutting watermelon, the cutting board or the bag for watermelon may cause the watermelon to have a lot of bacteria before it is put in the refrigerator.

Watermelon is stored for 3 months without rotting method:

1. Sand and soil cultivation method. In a clean, ventilated and sheltered place, spread 60 mm thick clean fine sand and take a sunny day.

Seven or eight ripe watermelons harvested in the early morning, leaving 3 leaves, and cutting with plant ash.

After pasting, gently put a layer, then cover with 50 mm of fine sand, and leave the melon leaves outside to make nutrients. This method can keep the watermelon fresh for 3 months.

2. Salt water sealing method. Select the well-ripened watermelon after harvesting, soak it in salt water for 2 4 hours at 5 10, and then use potassium sorbate.

or sorbic acid smeared on the surface of the watermelon, sealed in polyethylene plastic.

Store in a low temperature place (e.g. basement). This method can be stored for more than half a year.

3. Melon vine juice membrane method. Select intact ripe watermelon, spray it with 300 times dilution of melon juice on the surface, form a thin film when it dries slightly, and store it in a cool place. Melon cranberry juice is the juice filtered by grinding fresh watermelon stems into a pulp, which plays a role in preserving freshness because the stems and vines of watermelon contain substances that inhibit the ripening and respiration of watermelons.

This method can keep it fresh for several months.

Cut the watermelon and preserve

1. Before cutting the watermelon, be sure to clean the watermelon, wipe it dry and then cut it to minimize the invasion of germs.

2. After cutting the watermelon, put it in the refrigerator as soon as possible to keep it fresh, and you can't wait for half of it to be eaten before processing the other half.

3. Use plastic wrap.

When wrapping watermelon, you should not only cover the flesh side of the watermelon, but wrap half of the watermelon whole to make a closed environment. The watermelon processed in this way can stay in the refrigerator for at least 1 week without affecting consumption.

Cut watermelons are not easy to preserve, and at room temperature of twenty or thirty degrees in summer, they will become sour and deteriorate after only a few hours.

Here's how to store watermelon for 3 months without rotting:

1.Sand storage method: spread a layer of 5 cm thick fine sand in a cool and ventilated place, cut the watermelon, remove a layer of pulp on the surface, and then put it in the sand storage box, a layer of watermelon and a layer of sand, the top layer should be covered with 5 cm thick fine sand, the sand should be kept moist, sprinkled regularly, and can be stored for about 1 month.

2.Cellar storage method: After the watermelon is ripe, pick it in the morning on a sunny day, spread a layer of straw mat in the storage place, and gently place the watermelon on the straw mat, and the watermelon should not be stacked too high to avoid crushing damage.

The humidity in the cellar is high, and the floor is covered with a layer of fine sand or fine soil to reduce the evaporation of watermelon water.

3.Storage method in a cool place: Put the whole watermelon in a cool and ventilated place for about a week.

4.Cold storage storage method: Beat the watermelon into a pulp, put it in a container, and then put it in the cold storage for refrigeration.

It is important to note that watermelon should be eaten as soon as possible after it is cut to avoid infection with bacteria.

Watermelon can be stored at room temperature for up to 15-20 days Several watermelon storage methods may wish to try: 1. Sand storage with leaves Choose a ventilated, bright, clean and cool house as a storage room. In the morning and evening on sunny days or cloudy days, choose 7-8 ripe, no mechanical damage, and watermelons with intact skin for storage.

When picking melons, leave 1-3 leaves on the melon stem, and then knead it into a small round paste with damp plant ash at the broken point, and transport it back in time, do not vibrate too much during transportation to prevent damage. Before storage, spread 7-10 cm thick clean fine sand in the storage room, put the watermelon lightly on the fine sand one by one, cover the melon with a layer of sand, and expose 1 2 melons upwards, so that the melon leaves expose the melon surface. Spray 500 grams of potassium dihydrogen phosphate solution for every 100 watermelons, and then spray every 7 days, and the storage period can reach 15-20 days.

2. Storage in plastic bags After soaking the selected watermelon in 15% salt water for 3 minutes, remove it and put it into a plastic bag, seal the bag tightly, and store it for 10 days. 3. Cover soil storage Spread a layer of grass on the ground in the back sun, put a layer of watermelon and then cover a layer of film and a layer of 10 cm thick fine soil, which can store watermelon for 60 days. 4. Storage in the cylinder After disinfection of the cylinder with 500 times potassium permanganate, spread 3 cm thick hydrated lime at the bottom of the cylinder, and then put the selected watermelon into the cylinder in layers, and the cylinder mouth is covered tightly with plastic film, covered with a wooden cover, and the watermelon can be stored for 30 days.

5. Indoor storage Spread a layer of 3 cm thick river sand on the indoor ground, place the watermelon on the river sand, put 3 layers, and cover the top with plastic film, which can store the watermelon for about 20 days. Two scientists from the USDA's Agricultural Research Laboratory selected different varieties of watermelons and stored them at 21 degrees Celsius, 13 degrees Celsius and 5 degrees Celsius for 14 days. The results showed that watermelons stored at 21 degrees Celsius had the most adequate nutrient content (lycopene increased by 40 and carotenoids increased by 50 to 139) compared to when they were first picked, while watermelons stored at low temperatures had much less nutrient growth.
