How to store winter dates for a long time?

1. The time of harvesting.

The ripeness of picking has a great impact on the storage life, the lower the maturity of winter jujube, the more resistant it is to storage, with the initial red fruit (coloring below 25) being the most storable, and the whole red fruit (100 coloring) being the least storable. If it is stored for the purpose of fresh food, it can be harvested in the semi-red period, if it is for the purpose of processing, it can be harvested in the early red period, and if it is stored for a short time, it can be harvested in the whole period.

2. Temperature and humidity.

In the temperature range above the freezing point of winter jujube, the lower the temperature of winter jujube, the better the storage effect, and when the temperature is lower than the freezing point, frostbite will occur, resulting in damage to winter jujube. The freezing point of winter jujube with different maturity will also have certain differences, under normal circumstances, the freezing point of semi-red jujube is around and about and the early red jujube is higher than this value. The freezing point of whole jujube will be lower than this value.

Therefore, winter dates in the ripening period of different situations should be stored separately. Winter jujube is a fruit that is very prone to water loss, and the humidity suitable for winter jujube storage under refrigerated conditions needs to reach 90 95.

3. The content of O2 and CO2 in the modified atmosphere storage.

With the current freezing technology, winter dates are very suitable for storage in a modified atmosphere warehouse. Under the condition of refrigeration in controlled atmosphere storage, the O2 content of winter jujube needs to be controlled at 3 -6. In the storage environment with high temperature control accuracy, the O2 content should be correspondingly low, which can improve the preservation quality.

If it is a storage environment with a large temperature error, the O2 content needs to be high to prevent anaerobic respiration or CO2 poisoning.

Winter jujube trees are very sensitive to CO2, not suitable for storage in fully sealed packaging, if the CO2 content is higher than 5, it will accelerate the softening and browning of winter jujube, so the suitable CO2 content is 2 4. Packed in thick PVC perforated bags to prevent CO2 poisoning and maintain humidity inside the bag.

After harvesting, winter jujube is generally stored in controlled atmosphere storage and cold storage, which can inhibit the production of ethylene in winter jujube under low temperature conditions. The temperature of cold storage is about 1 is the best, and its relative humidity should be maintained at about 98%, waiting for the market during the New Year's Day and Spring Festival.

If you want to keep winter dates for a longer time and keep them fresh, then they should generally be placed in a cool and ventilated place, the temperature should not be too high, and avoid direct sunlight.

The refrigerator storage of winter dates is the same as other foods, and it can also be stored in the refrigerator, and the low temperature environment in the refrigerator can prolong the time for winter dates to deteriorate and rot, and play a role in short-term preservation, but it must be noted that it is placed in the refrigerator of the refrigerator, and must not be put in the freezer.

After the winter jujube is purchased, the bad jujube with bruises on the surface or black spots and insects is picked out to avoid the bad jujube containing mold from infecting other jujube during storage. Then seal it with a plastic bag, leave a small amount of air in the bag, seal it well, and then put it in the refrigerator at a temperature of 0 -4 to refrigerate. 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.

The way to keep winter dates fresh for a longer time is to use a plastic bag, pack winter dates, leave a small amount of air in the bag, seal it, and put it on the refrigerator door.

1.Pick out the bad jujube before storage After the winter jujube is purchased, select the bad jujube with bruises on the surface or with black spots and insects, so as to avoid the bad jujube containing mold from infecting other good jujube during storage.

If there are more jujubes that need to be preserved, it is advisable to pre-cool them first If there are many winter jujubes that need to be preserved, it is best to pre-cool the fresh jujubes to be stored at a temperature of 5-8 for 1-2 days before refrigeration.

Sealed plastic bags and put in the refrigerator for refrigeration The method of home preservation generally uses refrigerators, and the winter dates bought back are not all red and picked out, sealed with plastic bags, leaving a small amount of air in the bag, and then sealing.

If you don't use the refrigerator to store it, you can also put the winter dates in a fresh-keeping bag or fresh-keeping box, and then store them in a cool and ventilated place, so that you can maintain the freshness of the dates.

To store winter dates at room temperature, you can wash them to control the moisture, keep them dry, seal them in a fresh-keeping bag or fresh-keeping box, and store them in a cool place to avoid direct sunlight.

First of all, put the selected winter dates into a fresh-keeping bag, leave a small amount of air in the bag, and then seal it, and then put it at a temperature of 0 4.

Eat as soon as possible after washing Try not to put it in the refrigerator again, otherwise it is easy to dry up and rot, and it can only be stored in the refrigerator for 2-3 days.

First of all, wash and dry the winter dates. Then put the winter dates in a crisper bowl, seal them and put them in the refrigerator. If you don't use the refrigerator to store it, you can also put the fresh dates in a fresh-keeping bag or crisp-keeping box, and then put them in a cool and ventilated place.

You can take a dry towel, dry the moisture on the surface of the winter dates, and then prepare a fresh-keeping bag, put the winter dates in and tie them tightly, and use a vacuum machine to extract the air and put it in a ventilated place.

It is best to store it in a cool and dry place, so that it will be stored for a longer time, and try not to put it in a place where the sun is directly reached.

Winter jujube images are stored fresh, and if the freshness time is long, you can directly put it in a refrigerated popsicle, and then you can eat it directly.

Put the winter dates in a plastic bag and seal them, then leave a small amount of air, seal them, and put them in the refrigerator for refrigeration, so that they will keep fresh for a longer time.

The storage method of winter dates is to seal it so that it is not breathable, and it is best to vacuum pack it, so that it will be left for a longer time.

How to keep winter dates for a long time is generally sealed in a small bag, and then placed in a dry and cool place.

Winter dates can be kept fresh in the refrigerator. But this fruit is not suitable for long-term storage.

I want winter dates to be stored and kept fresh, and if they are long, you can keep them in the refrigerator.

My personal suggestion is to put the winter dates into a sealed bag, and then pump out the air in the sealed bag, which can be in a vacuum state, so that the sealing time is the longest.

The method of preserving fresh jujube at home generally uses the refrigerator, in the fresh jujube bought, the fresh and intact and the peel is not all red are picked out, sealed with a plastic bag, a small amount of air is left in the bag, and then sealed well, and then put it in the refrigerator with a temperature of 0 4 for refrigeration. When packing plastic bags, it is best to divide them into small bags, and each time you open a small bag to eat, you can keep the fresh dates for a little longer.

If you don't use the refrigerator to store it, you can also put the fresh dates in a fresh-keeping bag or fresh-keeping box, and then store them in a cool and ventilated place, so that you can maintain the freshness of the fresh dates.

If the quantity of fresh jujube is large, the fresh jujube to be stored needs to be pre-cooled at a temperature of 5-8 for 1 2 days before refrigeration. After pre-cooling, the fresh jujube can be stored in a cold storage with a temperature of 0 1 and a relative humidity of 90% and 95%.

The longest way to preserve winter dates is as follows:

1. Refrigerated storage

If it is a complete unwashed winter date, you can use a fresh-keeping bag to divide the winter dates into small bags and pack them, before putting them, it is recommended to pick out the bad dates with injuries and spots on the surface, leave a little air inside, and then put them in the refrigerator, and the proposal can be stored for 2-3 weeks.

2. Pre-cooling in advance

If it is a large number of winter dates, it is recommended to soak fresh dates in a solution of 2% calcium chloride for 30 minutes. Then put it at a temperature of 5-8 for 1-2 days, and then put it in a refrigerator with a temperature of 0-4 and a relative humidity of 90%-95%.

3. Cool and ventilated place:

If you don't use the refrigerator to store it, you can also put the winter dates in a fresh-keeping bag or fresh-keeping box, and then store them in a cool and ventilated place, so that you can maintain the freshness of the dates. It should be noted that after the fresh jujube is purchased, it is necessary to select the bad jujube with bruises on the surface or with black spots and insects, so as to avoid the bad jujube containing mold from infecting other fresh jujube during storage.

Washed winter dates must be eaten in time, generally speaking, it is best not to put the washed winter dates in the refrigerator for preservation, which is easy to spoil.

If you must put it, you should also wipe the water dry until there are no water droplets, otherwise it is easy to cause the winter dates to dry up or even rot and deteriorate after losing moisture. Put it in the refrigerator and remember to pack it in a plastic bag or plastic wrap, don't put it directly in the refrigerator, even if you don't put it in the refrigerator, it is best to dry the water and store it in a cool and unventilated place.

Hello, there are two ways:1Refrigerator preservation:

Seal the selected winter dates with a plastic bag, seal the plastic bag with a small bag, leave a small amount of space in it, seal it, and put it in the refrigerator at a temperature of about zero to four degrees. 2.Fresh-keeping bag preservation:

Put winter dates in a plastic bag and store them in a cool and ventilated place to maintain their freshness, and they can be taken anytime and anywhere without any limitations.
