07/31 1Boiling water treatment method. Put it in boiling boiling water and blanch it, then quickly remove the jujubes, dry the water and dry them in the sun, which can kill the bacteria on the surface of the jujubes, and store them in a dry and moisture-proof sealed container to avoid insects and deterioration of the jujubes.

2.Refined salt "standing guard" method. Take a ceramic container with a lid that can be sealed, wash and dry it before setting aside.

After putting a layer of red dates in the container, put in a thin layer of refined salt until all the red dates are put in, and then sprinkle a layer of refined salt on top of the top layer of red dates, and then cover and seal it. Because edible refined salt contains the effect of sterilization and preservation, it is the same as sentinels, and because sweet foods can be sweetened with a little salt, these sentinels will not make jujubes salty.

It is best to eat red dates in the stomach

It can be exposed to the sun for four or five days before Qingming.

Jujubes are afraid of wind, high temperature and humidity. It is easy to dry and shrink after being exposed to wind, and the skin color changes from red to black; High temperature, humidity is easy to pulp, insects and mold.

Storage method: It can be exposed to the sun for four or five days before Qingming.

To prevent blackening, you can cover the dates with a layer of mats, or spread them out in a ventilated and cool place for a few days. After drying, put it in the jar, add a wooden lid or mix grass and wood ash, and put it in the bucket to cover it. You can also use 30 grams to 40 grams of salt, fry it into powder, sprinkle it on 500 grams of red dates in layers, and then seal it, so that the red dates will not be bad.

The following methods are acceptable.

1. Refrigeration and insect prevention, freezing and insecticide.

2. The jujube is stored with nitrogen filling method for low oxygen.

3. Seal after fumigation and insecticide with aluminum phosphide, this attention is anti-poison.

4. Drying at high temperature to kill insects. The high temperature is 60 to 80 degrees Celsius to kill insects.

Put the dried jujube bought into the water and wash it, drain the water and put it in the pressure cooker to "steam" (not boil), wait for the pressure valve when the pot is steaming, steam for 7-10 minutes, turn off the fire, let it cool naturally, open the pot and take it out and store it in a clean container, take it as you eat, the jujube has been saccharified, the surface is shiny, a little blacker than the unsteamed, and the summer can avoid insects and deterioration of the jujube.

The storage method of jujube in summer without insects and mildew.

Method 2: Refrigerate.

Because the jujube itself is very sweet, occasionally the jujube is easy to grow insects in summer, please seal it and put it in the refrigerator for freezing, it does not affect the taste, in the process of eating, identify whether there are insects in the jujube and pinch it with your hand to feel it, if the feel is very good, if the feel is empty, please break it open and see before eating. If you can eat it in a short period of time, you can put it in the refrigerator to prevent the jujube from turning sour when the temperature is too high.

In order to avoid the hatching of eggs after the temperature rises in the future, the eggs are either frozen in the refrigerator at minus 18 degrees Celsius for a month, and then taken out for storage. Either bake it on high heat and use the heat to kill the eggs.

If the room temperature is not treated, it is easy to grow insects when the temperature is high.

After the dates are dried, they can be placed in the freezer compartment of the refrigerator. No worms, very safe.

1. Natural preservation: first put the jujube in a clean carton, then place the carton in a dry and ventilated place, and turn the jujube in the box every once in a while, if you find that it has been eaten by insects, you can remove it in time.

2. Drying and preservation: first dry the fresh jujube into red jujube or make it into processed products such as drunken jujube and candied jujube, in order to prevent the jujube from darkening in the process of drying, you can cover the jujube with a layer of cloth, put it in the jar after drying, add a wooden cover, or mix some plant ash, and put it in the bucket and cover it.

3. Cryopreservation: first pick out the fresh and intact and the peel is not all red, seal it with a plastic bag, leave a small amount of air in the bag, and put it in the refrigerator with a temperature of 0 -4 after sealing.

Because the jujube is relatively sweet, it is easy to become worms in the summer, you can put the jujube in an airtight jar, put it in the refrigerator, choose to freeze it, or you can put the bought jujube in water and wash it, put it in a pot and steam it for 7 to 10 minutes, let it cool naturally, and then put it in a container.

Pick the fresh jujubes that have been picked, and pick out the bad jujubes with bruises and black spots on the surface, so as to avoid the bad jujubes with mold during the storage period from infecting other jujubes and affecting the storage. Soak the fresh dates in a solution of 2% calcium chloride for 30 minutes, and then pre-cool them at a temperature of 5-8 for a day or two. After pre-cooling, the fresh jujube can be stored in a cold storage with a temperature of 0 1 and a relative temperature of 90% and 95%.

I think how to store jujubes so that they don't have insects? Let me tell you: Dry the red dates, put a little bit of Lai Shu, and then put them in the refrigerator so that there will be no insects in the future.

Are red dates dried, if you want to store them so that there are no insects, then put them in freezing.

In order not to let it have an effect, but I'm going to empty it and put it in the freezer.

Put it in the box, put it in the refrigerator.

1. Northern storage method.

When storing in large quantities, sacks are used for palletizing and storage, and when stacking, there should be a ventilation gap between bags and bags, and between stacks and stacks, so as to facilitate ventilation. The walls are somewhat damp, so don't get too close to the walls.

2. Southern storage method.

The southern region has high temperature and humidity, and should be stored in cold storage in the mildew season, and the jujube is packed in a sack and stored in the warehouse of 5. Before leaving the cold storage, it should be moved to a slightly higher temperature place for transition, and gradually moved to the outside of the warehouse. In order to prevent the condensation of water from the jujube fruit into water droplets, do not re-bag it immediately, but spread it out, wait for the condensation droplets to disappear, and then change the bag to package it for shipping.

How to properly preserve our dates. In this way, the jujube will not have insects and will be stored for a longer time.

The specific operation method is very simple, first prepare a bag, dried red dates, and hold on to the bag. At this time, we squeeze all the air out of the bag. Squeeze the bag tightly down so that there is no air circulating in the bag.

Then seal the bag again. Once it's tied, put it in a cool and ventilated place. Because bugs can't survive in a vacuum.

In this way, it can effectively avoid jujube insects.

The second method is to find a plastic sealed box or a sealed box of glasses, and then pour the dates into it. It is important to note here that the sealed box must be clean. And in the case of no moisture, otherwise it is easy to rot.

Once packed, prepare a paper towel. Pour an appropriate amount of tea leaves on a paper towel, and if you don't have tea leaves, you can also use edible salt instead.

Then wrap the tea leaves in a paper towel. In this way, the wrapped tea can be placed in our sealed box, and the lid is closed to seal it. In this way, it can ensure that the red dates in the sealed box have a drying effect.

In this way, our jujubes can be preserved for a long time, and there will be no insects.

With the acceleration of the pace of life, more and more people are paying more attention to health, all those who pay attention to health will stock some red dates at home, people often use red dates to make porridge, make tea, soak water to drink, etc., red dates play an increasingly important role in people's lives, especially women, they have a soft spot for red dates. But there will also be more and more problems of jujube insects, and many people often have these embarrassing problems when eating jujubes. So let's talk about how to prevent jujube insects.

Step Method:

1 First of all, we use the most convenient method is the boiling water treatment method, first blanch the jujube in boiling water, quickly remove and drain, and then put it in the sun to dry, wait to kill the bacteria on the surface, and then store it in a dry and clean container. Another is the microwave method, in which the jujube is placed in a glass turntable in the microwave oven and heated on high heat for half a minute to kill the bacteria on the surface.

2 The table salt we often use can also prevent jujube insects, find a ceramic container that can be sealed, and then wash it for later use. Then spread a layer of red dates in a ceramic container, and then put in a layer of refined salt until all the red dates are put in, and then add the top layer of red dates to sprinkle a layer of refined salt, and seal it with a lid for preservation, which can play a role in sterilization and preservation.

3 The last method is to use the refrigerator that we must have at home, because the temperature of the refrigerator is relatively low, so it can be cooled to prevent the invasion of microorganisms to achieve the effect of freshness, but it should be noted that the temperature should not be too low, which will affect the sweetness and nutritional structure of the dates, just a proper low temperature.

Precautions. The above are some of the methods commonly used at home to prevent jujube insects, we can try to use these methods at home, not only to prevent insects, but also to eat delicious jujubes at any time.

I always freeze jujubes in the freezer compartment of the refrigerator.

1. Soak the jujube in boiling water, quickly scoop it up, drain the water and dry it in the sun, and then put it into a moisture-proof vessel to prevent insect bites.

2. Put a layer of salt at the bottom of the tank or tank and other containers, then put a layer of jujube, sprinkle salt on top, store it layer by layer, until it is full, and seal it in a cool and dry place. Generally, 100 grams of salt are used per kilogram of jujube, and fine salt is appropriate, which can be used repeatedly and repeatedly.

3. Break the jujubes, remove the pits, dry them with a roaster until they are yellow and brittle, and put them in a container for preservation.

Because Sun Nianwei has a lot of sugar in jujubes, and it is particularly rich in nutrients, such as rich in protein, fat, sugar, carotene, B vitamins, vitamin C, etc., in the characteristics of disturbing Kaixiang, it is suitable for insects to supplement nutrition, and insects survive in jujubes by virtue of their survival instincts, absorb nutrients, and survive, so if they are not well preserved, they will have insects.

If you eat it, you should put it in boiling boiling water and scald it to kill the insects, and then put it in the sun to dry before eating.

Jujube is developed from flowers, and the core of jujube is developed from the stamen, which is also a worm**. When the jujube flowers bloom, the first eggs of some insects will be buried inside the stamens, and when the jujubes are mature, they will be picked and stored for a long time, and the eggs inside will hatch out of the insects under the condition that the moisture, air and temperature of the outside world are suitable.

After the jujube gall mosquito germinates in spring, it should be controlled with dichlorvos plus larvae before leaf rolling. One more general spray on the 10th day after the occurrence of the first generation can control the occurrence of subsequent generations. Scale insects are controlled with oxidized dimethoate during the critical period when the newly hatched larvae crawl out of the mother before and after the wheat harvest and the wax shell has not yet secreted wax.

When jujube bugs occur, use enemy killer emulsifiable concentrate to prevent and control. When jujube and stinging moth occur, pyrethroid pesticides are used to control them. From July to October, the longhorn beetle uses a small shovel to remove the topsoil around the root and neck, finds the worm hole, injects dichlorvos emulsion or pyrethroid pesticides into the wormhole with a syringe, and plugs the wormhole with soil to kill the larvae.

Clean up the branches, leaves, and fruits on and under the trees, and burn them in a centralized manner to reduce the source of overwintering insects. In mid to late April, when the jujube tree sprouts and spreads its leaves, the following agents are sprayed: 40% oxymethoate EC 1000 1500 times solution; 25% chlorpyramide suspension emulsion 1000 1500 times; Toxic chlorine emulsifiable concentrate 2500-3000 times liquid.

10% cypermethrin EC 2000 3000 times liquid; 20% emulsifiable fenvalerate 1000 2 000 times liquid; deltamethrin EC 2000 4000 times liquid; 20% hydroamidophos emulsifiable concentrate 400 500 times liquid; 25% thiazinone wettable powder 1000 1500 times liquid; 80% dichlorvos emulsifiable concentrate 800 1000 times, spray 1 time every 10 days, spray 2 3 times in a row.

1. Vacuum sealing, the best way to preserve jujube is to use vacuum packaging, which not only avoids jujube contact with the outside world, but also prevents bacterial breeding.

2. If you want to avoid the growth of red dates, you can first scald the red dates with boiling water, which can kill the bacteria and insect eggs inside, and then store the hot red dates in a dry sealed container after being blanched.

3. Salt preservation method, in addition to the above two methods, you can also choose to use salt preservation method, it is generally recommended that 1000 grams of red dates, you can use 25 grams of refined salt, put the salt into the wok to heat and sterilize, cool and set aside, put a thin layer of refined salt in the container after putting a layer of red dates, until all the red dates are put in, and then sprinkle a layer of refined salt on the top, and then cover and seal, because the edible refined salt has the effect of sterilization and preservation, to ensure the quality of the red dates. And because sweet food can be sweetened with a little salt, it will not make the jujube salty.

Method 1: Use boiling water for treatment. Put the jujube into boiling water and boil it, then take it out, drench the water and dry it in the sun, which can achieve the effect of killing the bacteria on the surface of the jujube, so that when preserving, a large number of jujube insects can be avoided to a certain extent;

Method 2: Prepare a larger bag first, then put the jujube into the bag, drain the air inside, and store it in a vacuum, isolating the air, the insects cannot survive in the vacuum environment, and it is a good way to avoid the jujube insects;

Method 3: Prepare a clean large container, heat and disinfect with salt, put the jujube into the container, spread a layer evenly, sprinkle a layer of salt, then put a layer of jujube, and finally sprinkle a layer of salt, cover the lid, so that the use of salt has a bactericidal effect, and can also well avoid jujube insects.

Red jujube, also known as jujube, dried jujube, jujube, originated in China, has been planted for more than 8,000 years, since ancient times has been listed as one of the "five fruits", has the title of "vitamin king".
