How long is the shelf life of dried jujubes, and how long is the shelf life of jujubes

Jujubes according to the water content.

No, shelf life at room temperature.

Generally within one year, the refrigerator insurance can extend the shelf life by two to three months. The jujubes on the market are basically transported and stored at room temperature after leaving the factory, so the shelf life of these jujubes will not exceed one year in theory, specifically: due to the relatively high water content of fresh jujubes, the general shelf life ranges from 6 months to 9 months, and the shelf life of air-dried jujube products with low water content is generally one to one and a half years at room temperature!

On the contrary, if the shelf life of fresh jujube is more than 1 year, it must be that there are preservatives added in the production process.

Or preservatives, if you see fresh dates (with relatively high water content) on the market with a shelf life of more than one year, no matter how cheap ** is, you should buy them carefully, after all, they are all things you want to eat.

The shelf life of dried jujube is generally 12-24 months. In the case of unopened, the shelf life may be extended by two to three months if stored properly. It is recommended to store in a cool, dry place away from moisture and direct sunlight.

If the jujube has discoloration, peculiar smell or insect damage, it should be stopped.

Fresh jujubes are the healthiest when they are purchased and eaten within a week; However, dried jujube is different, because most of the water is dried and evaporated, so its shelf life will be greatly extended, and the specific shelf life of bagged dried jujube is subject to the manufacturer's mark on the packaging bag; Generally, after opening the bag, it is best to eat it within 1 month.

If it is a bulk jujube, the shelf life is closely related to the preservation method and environment; As long as the bulk jujube is not washed, placed in a cool, dry and ventilated place, the temperature is controlled at about 1 to 10, and its shelf life is about 10 months.

Jujube should not be stored in a high temperature and humidity environment, and it is easy to ferment and deteriorate.

The shelf life of jujubes is generally one year. According to national requirements, the shelf life of jujube after processing is 12 months, dry goods can last 36 months, and jujube can be kept for up to 24 months, but the nutritional value is not high. In addition, dried jujubes, as long as they are stored in a ventilated and dry place or in vacuum packaging with a moisture content of 10%, generally will not become moldy and have a long shelf life.

Red dates: Red dates are plants of the family Liaceae that turn red when ripe. It is often dried in the sun to make dried dates.

It is very high in vitamins and has the reputation of "natural vitamin pills". As a good nourishing product, red dates are known as "three dates in a solar eclipse, immortality". The origin is slightly the same as the original variety.

It is widely cultivated in areas below 1600 meters above sea level. The purpose is the same as the original variant.

Fresh jujubes have a shelf life of about one week; The bagged dried jujube shall be marked on the packaging bag by the manufacturer; Bulk dried dates are about 10 months old.

The shelf life of jujube depends on the environment in which it is stored or how it is shelf-preserved. Generally, fresh jujubes are the healthiest to eat within a week after buying them. However, dried jujube is different, because most of the water is dried and evaporated, so its shelf life will be greatly extended, and the specific shelf life of bagged dried jujube is subject to the manufacturer's mark on the packaging bag;

Generally, after opening the bag, it is best to eat it within 1 month. As long as the bulk jujube is not cleaned, placed in a cool, dry and ventilated place, the temperature is controlled at about 1 to 10, and the shelf life is about 10 months. One thing to remind everyone is that jujube should not be stored in an environment with high temperature and high humidity, which is easy to ferment and deteriorate.

How to store red dates?

1. Refrigerator preservation: first expose the jujube to the sun, and after the water is dried, put the jujube into a closed container such as a glass bottle or plastic container, and put it in the freezer layer of the refrigerator, and the storage time can be as long as one year.

2. Cabinet preservation: Seal the dried red dates and store them in the cabinet, but the cabinet must be clean, and there should be no traces of cockroaches and other insects and ants, and the storage time should be at least two months.

3. Cellar preservation: In the countryside or north, you can use the cellar and add dried red dates to store it in the cellar, which can be stored for about half a year.

Jujube is a dried fruit food, and there are no special requirements at presentShelf lifeHowever, the shelf life of bagged jujube is generally about 10-12 months, and it should be stored in a cool, dry and ventilated place, and the temperature should be about 1-10 degrees.

During the shelf life of jujubes, you need to always pay attention to whether there is any deterioration, if there are perforations at the end of the pedicle of the jujube or there is dark brown or brown powder, it means that it has been eaten by insects, and it needs to be cleaned out in time, and the remaining jujube should be eaten as soon as possible.

Jujube is suitable for people:

1. Suitable for food. Jujube is suitable for all ages, especially the elderly, teenagers, and women, and is an ideal natural health care product for post-illness recuperation. It is especially suitable for chronic liver disease, stomach deficiency and lack of food, cardiovascular disease, spleen deficiency and loose stools, and Henoch-Schonlein purpura.

Bronchial asthma, urticaria.

Allergic eczema, allergic vasculitis, lack of qi and blood, malnutrition, palpitation, insomnia, anemia, dizziness and other envy patients.

2. Avoid eating. Damp heat and internal enrichment, children with chancre and parasitic diseases, dental pain, phlegm dampness.

People who are overweight and those who have a full abdomen and a thick tongue coating.

Those who are tired should avoid eating. In addition, diabetes.

Patients should not eat too much; Moreover, fresh jujube should not be eaten more, otherwise it is easy to produce phlegm, help heat, and damage teeth.

The shelf life of dried jujube is 18 months according to the food law.

The methods of jujube preservation are: refrigeration method, traditional method of preserving jujube, and modified atmosphere method.

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. The lower the temperature in a certain temperature range, the better the storage effect, below 0 degrees, the respiration intensity of jujube is less than 50% of the respiration intensity of jujube at 20 degrees, 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 jujube fruit, it will cause frostbite to jujube fruit, and the freezing point of different jujube fruit is different, which needs to be further studied.

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.

Half a year to a year.

Vacuum-packed dried fruits have a shelf life of up to six months to one year, but once the package is opened, it is very possible that something will go wrong within the shelf life. Therefore, as long as this kind of food smells like hala smell, and is bitter and sour when eaten, it should be thrown away. If the taste is not crispy, it means that it has absorbed water, and it will quickly deteriorate, grow mold, oxidize rancidity, and you can't ask for it.

The shelf life is not equal to the last before time. After the expiration date, some foods are still edible from a safety point of view, but their quality may be reduced to some extent.

It is no problem to store it in the refrigerator for a year and a half, if you do not use the refrigerator, it is easy to get insects. Fresh jujubes need to be spread out and cooled for a period of time, and then stored until the jujubes are dry, so that if they are kept in the refrigerator, they should be fine for a year.

But I will also find that when the cold is not thorough, even if it is placed in the refrigerator, there will be partial decay, and a few red dates a day are enough, if you need to store, it is best to place them in the freezer layer of the refrigerator, not in the refrigerator.

However, now, whether it is dried jujube or green jujube, it can be purchased on the market at any time, ** the fluctuation is not large, it is not recommended to store it for a long time, and it is generally recommended to eat it within three months. Therefore, it is advisable not to buy too much at once. It can be stored for three months in a place with good air flow and no sunlight, and it is best to put it in the refrigerator in summer, otherwise it will grow insects and mold.

Look at whether you are fresh or dried dates, you didn't make it clear!

Tianyak is right, why should it be kept for so long, it is not necessary.

If the shelf life must be investigated, the shelf life is marked on the packaging bag of the product.

There is no special shelf life for dried fruit products. According to national requirements, the shelf life of jujube is 12 months after processing. Up to 36 months for dry goods! However, jujubes will be stored for a maximum of 24 months, and there is no problem with any more, but the nutritional value is not high!

At least six months, dispersed and packaged, cool, dry, and can be a little longer.
