How do you store the mandarin oranges picked after the year? How to keep freshly picked oranges long

Pack it in a plastic bag and leave it out for a longer time without touching the air, but the oranges must not be kept fresh in the refrigerator, as doing so will speed up the decay of the oranges.

Remember not to pack the citrus after the year to store, so that the oranges are easy to rot, if there is a condition, you can put it in the cold storage, if there is no cold storage, store it at room temperature, pay attention to the oranges do not pile up too high, the bottom is covered with straw and other items to prevent moisture, and then cover the oranges with plastic film or cloth to prevent the moisture of the oranges.

Citrus is preserved after harvest, and it can be soaked in fruit for 3 5 minutes with prochloraz, or thiophanatezim methyl, or carbendazim, or azazole, or prometrium, or Tectole, or diphthofen, etc., and then the single fruit is packed in plastic film and placed in a ventilated and cool place. Among them, it is advisable to add kilograms of water per gram.

Pine leaves are preserved, spread the pine leaves at the bottom, and then put oranges, and then cover them with pine needles after they are placed, and so on, so that there is no problem in keeping them fresh for a long time, the moisture is quite sufficient, the key is to get pine needles, keep the oranges in the needle-like leaves filled with Masson pine, and place them in a cool and dry place, which is also a very good way to keep fresh.

Oranges are frozen and stored at room temperature, and those who have conditions are suitable for this method. If there is no freezer, put a film underneath to protect it from moisture. The most direct method is to seal and store it, tie it tightly with a bag and leave no air, so that oxygen will not rot if it cannot enter.

If the skin is thick, it is recommended to wrap it separately in a small plastic bag and tighten the bag mouth, which can isolate most of the oxygen and reduce the decay rate. Then spread a layer of film on the ground to prevent moisture, and then gently place the wrapped oranges on top of the film to minimize collision to avoid rot caused by collision. Finally, cover the surface with a film.

If you have an empty jar at home, you can put the picked oranges inside. If you don't have a jar, you can find a cardboard box or barrel to put it. But it's best to put it in the jar, so that it can be left for a longer time. It's no problem to leave it for a few months.

It is mainly suitable for the preservation of large quantities of commercial oranges, and the key point is to control the temperature and humidity of the frozen and cold storage. It is to coat the surface of the orange with a preservative and then air dry it for preservation. I got some pine leaves from the mountains and piled them up with the oranges, and I had to do the above, but sometimes I found one or two rotten ones.

My family buys a bag of oranges every Chinese New Year, and I usually put these oranges in a bucket and a vegetable basket respectively, and put them in a cool place to eat slowly.

In our family, we generally soak it in sugar water after cutting it, and then take it out after a certain period of time and let it dry outside.

Leave a piece of fruit to ensure that it will not break in a week after picking, and then we found out that this is not long enough for a new way to come out. Even if you cover the harvested fruit with straw and pine and cypress branches, it can be extended to about half a month, which is almost the limit.

Place in a breathable box and let in a cool, ventilated place. Let's take a look at it every other time.

I think the oranges picked in the afternoon should be kept in a cool place.

1. Temperature.

The storage temperature should not be too high or too low in the general range, so that the citrus will not be frozen, nor will it be too hot and dry, the higher the temperature, the shorter the shelf life, the faster it will deteriorate, and the lower the temperature, the slower the deterioration.

2. The oxygen content of the environment.

The less oxygen citrus has, the easier it is to preserve, as it is prone to deterioration due to oxidation.

3. The cleanliness of the environment.

Everyone knows that the cleanliness of the environment is crucial for the preservation of fruits, so the fewer bacteria in the environment, the easier it is for citrus to be preserved.

4. Humidity. The humidity of preservation also affects the preservation of fruits, so the lower the humidity, the easier it is for citrus to preserve.

In a high-lying interior, dig the ground, 60 80 cm deep and 80 100 cm wide, and build brick walls with bricks, or build a brick pool on the ground indoors, similar in size to an underground pool.

After disinfection and drying, clean the river sand or sun-dried rice and wheat stalks on the bottom mat of the pool, and then neatly place the citrus 5 8 layers. At the beginning of storage, the mouth of the pool is not tightly covered to allow the water to evaporate; When the temperature is low, cover the mouth of the pond, and cover the straw bales and quilts to keep warm when it is cold, so as to prevent the cold damage of the fruit.

During storage, a layer of fresh sawdust with a moisture content of about 7% can be placed at the bottom of the washed, dried and sterilized wooden box (barrel), and then a layer of citrus and a layer of wood chips can be stored in layers.

1. Choose varieties that are resistant to storage. Ponkan, navel orange, pomelo and grapefruit are more resistant to storage, followed by Wenzhou mandarin.

2. Pick good orange fruits. Pick oranges on sunny days, cut the bellflower flat when picking oranges, and pick them lightly. Avoid mechanical damage caused by orange harvesting.

3. Warehouse disinfection. Citrus can be stored in ventilation warehouses or ordinary housing. Clean the warehouse before storage and plug the rat hole.

And one week before the citrus is put into storage, it is sprayed and disinfected with 500 times carbendazim or methyl tobuzin. Doors and windows should be opened for ventilation 2 days before citrus storage to prevent damage from bacteria and affect the storage effect of citrus.

4. Anti-corrosion treatment. Citrus to be stored should be preserved on the day of harvest, and the maximum should not exceed 2 days. The preservative can be selected with 25 Shi Baoke 10 ml 2 3 g 2,4 d sodium salt 10 kg of water, 750 1000 kg of citrus.

The method is to soak the harvested citrus into the prepared medicinal solution, soak it for a minute, and then take it out to dry.

5. Ventilation and pre-storage. The preservative citrus is placed in a ventilated warehouse, the doors and windows are opened, and the air convection is used to disperse the peel water and dry it, which can effectively reduce the flavor of the fruit and the rotten fruit. The pre-storage time is generally 5-7 days, and if it rains during pre-storage, it can be extended to 10-12 days.

Usually the peel is dried, and the fruit weight loss is 3 5 It is appropriate. The pre-stored citrus can be stored in polyethylene film bag single fruit packaging, or naked fruit storage, and the fruit storage utensils can be used in wooden crates, bamboo baskets or rattans.

6. Storage method. When citrus is stored in the warehouse, the storage method can be selected according to the storage conditions and the size of the warehouse, mainly including "product" zigzag stacking, rack storage and local storage. Either way, however, there should be plenty of access and space for managers to operate.

7. Warehouse management. During the storage of citrus, the doors and windows of the warehouse are required to be shading, the temperature in the warehouse is generally maintained at 4 10, the relative humidity is 85 90, and the temperature difference between day and night is as little as possible. In the early stage of storage, high temperature and humidity are prone to occur in the warehouse, which shortens the life of citrus, during which ventilation should be strengthened and the temperature and humidity of the warehouse should be reduced as soon as possible.

When the outside temperature is lower than 4, close the doors and windows in time, block the vents with grass, strengthen the indoor cold and keep warm, and ventilate when the temperature is high at noon; In the later stage of storage, when the outside temperature rises to 20, the doors and windows should be closed, and ventilation should be implemented in the morning and evening or when the temperature is lower than 16. When the relative humidity in the warehouse drops to 80, the box of citrus should be covered with plastic film to moisturize. The covered film is 25 30 cm from the ground and should not be sealed; Stacked citrus can be topped with clean straw to moisturize.

At the same time, you can use methods such as sprinkling water on the ground or putting water in the basin to increase the air humidity. During storage, it is necessary to check regularly, and if you encounter rotten fruits on the floating surface, you can remove them at any time, but try not to turn them.

Peel and store directly into the stomach

Hello, the best way to save is:

1. Put it in a plastic bag, and you can leave it for a longer time without touching the air. But oranges must not be kept fresh in the refrigerator, as this will speed up the decay of oranges.

2Place the pine leaves (pine needles) on the bottom of the cardboard box, then put the oranges, and then cover the pine needles on top after they are placed, and so on. In this way, there is no problem in keeping it fresh for half a year, and it is full of moisture. That's what we do in our family, and the key is to get pine needles.

3. Use garlic or garlic head to mash or slice and boil water to soak citrus, which can keep oranges fresh for 4-5 months and have a good fruit rate.

The average is around 95%.

The specific method is: mash or slice the garlic leaves or garlic heads, and put them in clean water, and the ratio of garlic to water is 1:10

After soaking for 12 hours, it will be boiled to boiling point, and after cooling to room temperature, it will be strictly selected, unbroken skin, and none.

Soak the fresh citrus in garlic water for 10-15 seconds, remove the water and dry it, and then store it according to the usual method.

The principle of this method of storing citrus is that garlic contains natural chemicals that can be used as citrus.

Preservative. In this way, the peel of raw citrus fruit is smooth and shiny, with a slight garlic and spicy taste, and the flesh is not at all.

Other peculiar smells, harmless to the human body after eating.

1. Freezing and refrigeration method: It is mainly suitable for the preservation of large quantities of commercial oranges, and the key point is to control the temperature and humidity of the frozen and cold storage.

2. Chemical method: It is to coat the surface of oranges with preservatives and then air dry them for preservation.

3. Soil method: First, it is packed in a fresh-keeping bag and piled together; In addition, I got some pine leaves from the mountains and piled them up with oranges, and I had to do the above measures, but sometimes I found one or two rotten ones.

How to preserve oranges at home: Easily preserve them for a winter, so that you can eat fresh oranges at any time.

1. The oranges bought in the market are tied tightly with a fresh-keeping bag to prevent water evaporation.

2. Tie it tightly with a fresh-keeping bag to keep it fresh for a period of time.

3. Refrigerate in a plastic bag, and remove the ones that start to break.

4. Using garlic or garlic head to mash or slice and boil water to soak citrus can keep oranges fresh for 4-5 months, and the average rate of good fruit is about 95%.

The principle behind this method is that garlic contains natural chemicals that can be used as citrus preservatives. The raw citrus peel is smooth and shiny, with a slight garlic spicy taste, and its flesh does not have any other peculiar smell, which is harmless to the human body after eating.

1. If you want to store citrus better, you should pay attention to it when harvesting. Grasp the reasonable harvest time, and then use scissors to cut the citrus, do not pull directly, otherwise it will hurt the peel and affect storage. Generally, it is cut twice, first with the fruit stalk cut off, and then pruned, so that the citrus is not only picked, but also the orange tree is pruned reasonably.

2. The picked citrus must be placed carefully, and if there is a problem with its own quality, it should be disposed of in time to avoid infectious diseases.

3. If you store citrus in the cellar, this is a very common method, if it is a cellar that has been used before, it must be disinfected before you can put the citrus in.

4. Before putting it in, spread some straw at the bottom to prevent moisture at the bottom, and then pile the citrus into a small pile, not too much, so as not to crush the citrus below. Pay attention to care when placing it, and the fruit is facing the upper section, not that you can pour it in casually. Then every other week or so, pay attention to the check-up.

If there is a rotten grip, or if there is a problem with the Luyou Guodi, clean it up quickly.

5. Relatively speaking, sawdust has the effect of moisture absorption, and the effect is very good when using sawdust to store citrus. First of all, the sawdust should be clean, and then put them in the sun to dry again to reduce moisture. Then lay a layer of sawdust, then a layer of citrus, then a layer of sawdust, and then a layer of citrus, pay attention to the thickness of the sawdust, at least four centimeters.

6. In addition to the use of sawdust, you can also spread grass ash, or sand, which can basically be stored for about 3 months.
