How to store dried jujubes, how to store fresh jujubes

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

During the mildew summer, one is to put a sack on top of each bag of dried dates, which is conducive to isolating moisture. The second is to pay attention to closing the doors, windows and ventilation holes of the warehouse. When the outside temperature is low and dry, the air in the warehouse is discharged and replaced with dry air.

Lime moisture absorption points are set in the warehouse, which can significantly reduce humidity.

When the storage capacity is small, it can be stored in the cylinder (altar), and the mouth of the cylinder (altar) is tightly sealed with plastic film and placed in a cool place to spend the summer safely.

In the south, high temperature and humidity, mildew season should be stored in cold storage. Dried dates are packed in sacks 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.

A small amount of dried jujube can be stored with rice husk ash. Sprinkle dry rice husk ash about 1 cm thick on the ground, spread a layer of dried dates, then sprinkle rice husk ash to cover the dried dates, and then spread a layer of dried dates. Such a layer of rice husk ash and a layer of dried jujubes can be stacked 30 40cm high.

This storage method can prevent moisture and sterilization, and the jujube grains are dry, and the effect is better.

Cold storage is refrigerated at low temperature, whether you eat it yourself or do business.

1. Sand storage

Select storable varieties, harvest at the beginning of red to semi-red, select harmless jujube fruits, choose a cool and damp place, lay 3 cm thick wet sand on the bottom layer, put a layer of fresh jujube (the thickness of a jujube), and then lay a layer of sand, then put the second layer of jujube, then spread sand, put the third layer of jujube, and so pile to 30 cm high. In order to prevent the sand from drying out, the surface layer can be sprayed with clean water to supplement the humidity. This method can be stored for more than a month, the jujube fruit is tender, crisp and sweet, and the nutrient loss is less.

2. Freezing

The preservation of fresh jujube should first choose the date of picking fresh jujubes, and pick them when the red fruits of jujube reach more than 25% coloring, and the jujubes at this stage are the most resistant to storage. Generally speaking, late-maturing varieties are more resistant to storage, and do a good job of choosing winter dates such as dipping winter dates, snow dates, September greens, etc. The fresh jujubes that have been picked should also be selected, and the bad jujubes with bruises and black spots and insects on the surface should be selected out, so as to avoid the bad jujubes with mold during the storage period from infecting other jujubes and affecting the storage.

3. Refrigerate

The method of home preservation is generally to use the refrigerator, pick out the winter dates that are not all red, seal them with a plastic bag, leave a small amount of air in the bag, seal them well, and then put them in the refrigerator with a temperature of 0 -4 for refrigeration. However, it is recommended that when packing plastic bags, it is best to divide them into small bags, so that you only need to open one small bag at a time to eat, and you can keep it for a longer time.

Related Notes:

Fresh jujube (also known as fresh jujube) refers to the jujube fruit that has not been processed and directly picked from the jujube tree. The nutritional value of fresh jujube is much higher than that of dried jujube, but it is not conducive to preservation due to the defects of preservation technology. Therefore, the shelf life of fresh jujube is relatively short, and it is recommended to pick and eat immediately.

There are many varieties of fresh jujubes, among which there are many excellent varieties, such as early and medium early varieties such as early crispy king, milk fragrant jujube, Ningyang June fresh, Xinzheng June fresh, to the mouth crisp, honey pot, pimple crispy, etc.; Medium-ripening and medium-late ripening varieties include large melon jujube, big white bell, Linyi pear jujube, and chili jujube; Jujube, no crisp, Chengwu winter jujube; Late-maturing varieties include winter jujube, Xingtai September green and so on.

1. Refrigeration method. Before storage, the jujube is pre-cooled and disinfected, the storage temperature is reduced to -2 degrees before pre-cooling, and the temperature in the storage temperature is kept at 0 degrees during pre-cooling, and at the same time, it is fumigated and sterilized with TBZ fog agent (3-6G M), and the jujube fruit is packed in the warehouse after pre-cooling, and the perforated polyethylene film bag is lined with the lining.

After the jujube is put into storage, it should be cooled down quickly, and the storage temperature is required to be 0 degrees, and the warehouse temperature is -1 degree. Temperature is the most important environmental factor affecting the storage life of fresh jujube.

2. The traditional practice of preserving jujubes. Mainly the fresh jujube is dried into jujube or made into drunk jujube and candied jujube and other processed products, used for preservation, although the sugar content of jujube is high and resistant to storage and transportation, but the vc content is only, reduced to less than 5% of the vc content of fresh jujube, the vc content of jujube can be maintained at 2mg g, but the processing of fresh jujube should be short and seriously affects the yield of jujube.

3. Modified atmosphere method. By adjusting the gas composition in the storage environment of jujube, it can regulate the respiration of the fruit and inhibit the growth and reproduction of microorganisms, so as to achieve the purpose of preservation.

Don't freeze, after freezing, it will completely change when it melts, and the texture and taste will be completely gone.

Fresh dates can be sealed in a plastic bag to squeeze out the air. It is better to bring branches with a few leaves.

But it can also be thought that to make "drunken dates", that is, seal it into a bottle, add water and a few drops of wine, and there should be no air.

You can find a bottle, put the intact dates away, pour a little wine, mine has been put for a long time, and it is the same as just putting it in, it is a little bit of wine.

Wine jujube: drunken jujube, a good way to store fresh jujube.

1. Pour the dried dates into a carton, put them in a cool and ventilated place, or put them in the refrigerator for refrigeration, be careful not to seal them, they can be stored for several months to a year, and they should be dried outside to prevent insect damage.

2. Jujube is afraid of wind, high temperature and humidity. It is easy to dry and shrink after being exposed to wind, the skin color changes from red to black, high temperature, humidity and easy to pulp, and insects become moldy.

3. Is dried jujube the flesh of jujube after air drying, it is best to store it in an airtight container to keep it fresh.

1. Boiling water treatment method: After picking out the shriveled jujube and impurities mixed in the jujube, put it into boiling water and blanch it, then quickly take out the jujube, pour it out of the water and dry it in the sun, which can kill the bacteria on the surface of the jujube, and store it in a dry and moisture-proof sealed container to avoid insects or deterioration of the jujube.

2. Bagging and collection method: put the sun-dried red dates in a bag, spray a little liquor, tie the bag tightly, and do not let the air leak, so that it can keep no insects all year round and can be eaten at any time. The second method: if possible, it can be refrigerated in the refrigerator and kept at a temperature of minus 15 degrees.

3. Refined salt method: take a ceramic container with a lid that can be sealed, wash and dry it for later use. If there are 1000 grams of red dates, go to 25 grams of refined salt, put the salt in a wok to heat and sterilize, let it cool and set 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, then sprinkle a layer of refined salt on the top, and then cover and seal. Because edible refined salt has the effect of sterilization and preservation, the quality of jujube is guaranteed. And because sweet food can be sweetened with a little salt, it will not make the jujube salty.

4. Simple family storage method: small amounts can be sealed and stored in a cool place after being packed with jars, bowls, jars, plastic bags, etc. When the amount is a little more, it is stored well with rice husk ash, and there is no pollution.

The method is: choose a clean, dry and cool cement floor house, first clean the surroundings and sprinkle lime powder, then spread 1 cm thick rice husk ash on the ground, and then spread a layer of red dates, so that a layer of rice husk ash and a layer of red dates are piled up to 30 40 cm. This method is moisture-proof and sterilization, and can be stored for 2 to 3 months.

The preservation methods of jujube are: indoor self-group storage, refrigerator low temperature storage.

1. Indoor natural preservation

Remove the plastic bag of the jujubes we bought back with packaging, and then put them in a cloth bag or store them in a cardboard box, and turn them frequently, which can help prevent insect pests.

2. Refrigerator low temperature storage

As long as there is a refrigerator in the living room of the house, it can be taken, it is very simple, you only need to seal the red dates in a plastic bag and put them in the refrigerator. If it is to be stored for a long time, it should be placed in the freezer compartment of the refrigerator. Remember to put the dates in a plastic bag next to the heater, as they are most likely to ferment and spoil.

The lower the temperature in a certain temperature range, the better the storage effect, below 0, the respiration intensity of jujube is less than 50% of the respiration intensity of jujube under 20, and the low temperature can slow down the transpiration rate of fruit moisture and inhibit microbial activity. However, if the temperature is lower than the freezing point of the jujube fruit, it will cause freezing or rolling injury to the jujube fruit.

Precautions for eating red dates

1. Jujube should not be eaten with cucumber and radish, which will destroy the vitamins of jujube, and it is easy to lose the nutrients of jujube, and they are not compatible.

2. Jujubes should not be excessive, because the sugar is relatively heavy, so for the sake of teeth, so don't eat too much at a time, and you will be thirsty.

3. When eating jujubes, you should eat them slowly and chew them well, because jujube skin is not easy to digest.
