How to dry jujubes, how to store them, and how to store fresh jujubes

Dried jujube Ingredients: There is no limit to the number of fresh jujube and Fuqiang powder.

Dried jujube Method: 1Wrap the flour (or other fine white noodles) in a white cloth and steam for 40 minutes. After taking it out, let it cool, rub the clumpy flour together, and set aside.

2.Choose ripe fresh jujubes with orange and red colors, and pick out jujubes that have pests and diseases. Use a peeler to peel off a thin layer of date skin.

3.Place the peeled dates on a mat or drawer, 3 4 cm thick, expose them to the sun for 2 3 days, turn them over twice a day, or spread them on the drawer, put them in a drying room, and bake them at 50 room temperature for 8 10 hours.

4.Pinch the jujube meat by hand, dry (or bake) it until it feels soft, and then take it out to cool.

5.Use an iron pipe to dig out the jujube pits.

6.Mix the cooked rich and strong flour with the prickly meat, so that each date is dipped in a layer of flour, and the excess flour is sifted out.

7.Spread the thorny meat on a mat or drawer, 3 4 cm thick, and expose it to the sun for 3 4 days; Or spread it out on a drawer and put it in the drying room and bake at 60 room temperature for 10 to 12 hours. With a little force by hand, you can pinch the jujube meat flat.

8.The thorny meat is kneaded into a flat oblong shape one by one, that is, Yongcheng dried dates. Be careful to protect from moisture when storing.

Find a sunny day, pour the dates on the ground (you can also spread something in advance) and let them dry with moisture, it will definitely not meet the requirements in a day, and dry it several times.

Then put it in a bag or plastic bag and place it in a dry place.

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.

The common methods of drying dates are as follows:

1. Plastic bag sun exposure: Put the jujube bag into a 10kg plastic bag, each bag is about 5kg, tie the bag mouth with a rope, and place it in the scorching sun to expose it to the sun, so that it can fully transpire the water in the body of the jujube fruit in the plastic bag, and pour out the jujube at night and release the water. On the second day, re-bag and blow the sun, and repeat for a week.

2. Cement floor sun exposure: choose the cement floor of Chaoyang, spread the jujube evenly, with a thickness of 8-10cm, cover the surrounding area with a large plastic sheet, and dry it under the scorching sun.

Jujube contains triterpenoids and cyclic adenosine monophosphate, which have strong anti-cancer and anti-allergic effects. Jujube contains anti-fatigue substances that can enhance human endurance, and jujube also has the effect of reducing the damage of toxic substances to the liver. The flavonoids in jujube have the effect of calming and lowering blood pressure.

Jujube is warm and sweet, with the effects of invigorating qi and blood, strengthening the spleen and stomach and wind, and has an ideal effect on the increase of serum aminotransferases in patients with Henoch-Schonlein purpura, anemia, hypertension, acute and chronic hepatitis and liver cirrhosis, as well as the prevention of blood transfusion reactions.

Jujube contains a variety of trace elements and rich nutrients, which have unique nutritional and medicinal value. However, fresh jujube is stored under natural conditions after harvesting, and the flesh will quickly brown and soften after only a few days of fresh crispness. After several years of experimental research, the author believes that in order to extend the storage and preservation period of fresh jujubes, the following key technologies must be grasped:

1. Choose storable varieties.

Generally speaking, late-maturing varieties are more shelf-stable than early-maturing varieties, and dual-use varieties have better shelf-stable properties than fresh food varieties. At present, the quality and storability of winter jujube are known as the "king of jujube fruits" in fresh jujubes. There are the following varieties of winter jujube that are more shelf-stable:

Dipping winter jujube, Daxue jujube, Xuecheng winter jujube, Chengwu winter jujube, September green.

Second, do a good job in pre-harvest management.

It is necessary to do a good job in the management of soil, fertilizer and water in the jujube orchard and the prevention and control of pests and diseases, so as to enhance the storability of the jujube fruit itself. Half a month before harvesting, calcium chloride solution and 1000 times methyl tobuzin solution were sprayed on the crown and jujube fruit to increase the calcium content of jujube fruit and prevent mold infection.

3. Master the appropriate harvest period.

Within a certain range, the lower the maturity, the more resistant it is to storage. Experiments have proved that the first red fruit is the most resistant to storage, so the storage of fresh jujube should be mainly red fruit.

Fourth, control the storage environment.

Practice has proved that the suitable storage environment conditions are as follows:

The freezing point of jujube fruit is lower than that of ordinary fruits, and the lower the temperature range above the freezing point of winter jujube, the better the storage effect. There are differences in the freezing point temperature of different ripeness, so winter dates at different maturity periods should be treated separately, and it is generally better to grasp them at 0 1. Under refrigerated conditions, the relative humidity suitable for winter jujube storage is 90% to 95%.

Under refrigerated conditions, the oxygen content should be controlled at 3% 6%. Winter jujube is a very sensitive variety to carbon dioxide, and the appropriate carbon dioxide content should be 2% 4%.

5. Adopt reasonable storage equipment.

On the one hand, the storage of jujube should have certain low-temperature and airtight conditions to reduce water loss and appropriately reduce the respiration intensity; On the other hand, it is necessary to maintain proper air permeability to prevent ethanol accumulation. Therefore, it is generally packed in millimeter-thick PVC perforated bags during storage, which can prevent carbon dioxide poisoning, and at the same time, it can also maintain the humidity in the bag and ensure the freshness of the fruit. Fresh jujube is stored at low temperatures, and is generally packaged in plastic sachets that can hold kilograms.

Soak 25% colored, harmless, disease-free jujube fruits in 2% calcium chloride solution for 30 minutes in advance, and pre-cool them for 1 2 days under 5 6 conditions. After the jujube temperature drops to 6 7, it is bagged, the bag mouth is tightened, and it is stored in a cold storage with a temperature of 0 1 and a relative temperature of 90% 95%.

In addition, it is necessary to do a good job in storage management, mainly including the adjustment of temperature, humidity and gas composition. At the same time, sampling and inspection should be carried out every 7 to 10 days, and the jujube fruits that should not be stored should be processed in a timely manner.

The method of drying dates is as follows: after the fresh dates are beaten, pick out the good dates, boil a pot of water, pour the dates into it, wait for the water to boil, take out the dates, and then pour the dates on a clean mat made of sorghum poles and dry them on the roof. Jujube has a very high vitamin content and has the reputation of "natural vitamin pill", which has the effect of nourishing yin and yang and nourishing blood.

Jujube flesh is thick, delicious and sweet in color, rich in protein, fat, sugar, vitamins, minerals and other nutrients, so jujube has always been a good health care product for qi, blood and nerves.

Several ways to eat jujubes.

1.Soak the dates in water.

Clean the jujubes, boil them in water, you can add some rock sugar, and continue to drink them for a week to increase the serum protein of the human body, so as to achieve the effect of liver protection and detoxification.

2.Red dates to boil porridge.

Tear the jujube and soaked white fungus into small pieces and cook porridge with rice, and add an appropriate amount of rock sugar when it is almost ready, this method can effectively relieve cough and moisten the lungs.

3.Red dates soaked in wine.

You can soak jujube in any kind of liquor, because the nutrient-rich organic matter will be more easily dissolved into the wine, which has a good effect on keeping the blood vessels open. In addition, you can also add some nourishing maintenance when soaking wine.

Such as: ginseng, deer antler, wolfberry, etc.

4.Red dates are steamed.

Wash the jujubes, put them in a steamer, steam them for 15-20 minutes, and then they are ready to eat. This method is more suitable for the elderly and infants, because the digestive function of the elderly and young children is not good, and it will be easy to put after steaming.

Peeling off the skin of jujube that is not easy to digest will make it easier to digest and absorb.

Drying method:

Dry the fresh jujube in a dry and ventilated place in the shade, and turn it once every 1 3 days, so that the jujube gradually loses moisture and becomes a dry jujube. This method is suitable for areas with many rainy days during the harvest period and varieties with thin flesh and coarse texture. The jujube obtained by this method is bright in color, relatively full in appearance, less wrinkles and lighter, and more beautiful.

Sun-drying method: choose a dry, flat and ventilated place to set up a drying field, and spread it on the brick with sorghum stalks, about 20cm from the ground, as a jujube shop. The jujube is spread into a high and low tile ridge shape, evenly spread on the jujube shop for exposure, the thickness is 6 10cm, 30 50kg per square meter of pavement is paved, and it is turned once every 1 hour or so to dry evenly up and down. At night, they are piled up in the middle of the bunks and covered with mats to protect them from dew and rain.

If the weather is clear, it can be dried in 10 days.

Baking method: Generally, a special baking room with coal and other raw materials should be built. The various forms of baking rooms are composed of several parts, such as a heating system, a ventilation and dehumidification system, and a loading system.

Baking method: Grade fresh jujubes according to size and maturity, pick out rotten jujubes, put them on the shelves separately, and the thickness should be 2 layers. Once plated and on the shelves, close the door and exhaust pipe and start baking. The whole baking process is divided into three stages: heating, evaporating water and drying.

During the heating phase, the temperature of the oven should rise slowly and steadily to 55; In the evaporation stage, the temperature is raised from 55 to 65 68, but should not exceed 70, and it is maintained for 8 10 hours; In the drying stage, the temperature in the oven is lowered to 55 for 4 to 6 hours. The whole stage is damp 1 2 times. In the later stage, pay attention to the selection of jujube plates that meet the drying requirements and leave the room at any time.

Dryer drying method:

This is a kind of drying equipment with high efficiency, and the commonly used ones are tunnel dryers, drum dryers and belt dryers.

Jujube is not afraid of freezing, it is best to move it less, if there is a cold storage is the best, you can put it in cold storage, if not, it can be placed in a cool and dry place after drying, but avoid turning it in the process of drying.

After the jujube is picked, soak all kinds of fruits with 500 times the liquid of the new high-fat film, soak the whole basket of jujube in the liquid for about half a minute, and then lift the fruit basket and drain the liquid into the fruit box or fruit basket, which can be waterproof and evaporated, prevent bacterial infection, resist frost and heat preservation, and prolong the shelf life.

How to dry fresh dates: Teach you to make dried dates, which are sweet, soft and delicious.

How do you store freshly picked dates? Teach you a little trick to store it for winter to taste better!

Fresh dates.

After beating down, pick out the good dates, boil a pot of water, pour the dates into it, wait for the water to boil, take out the dates, and then pour the dates on a clean mat made of sorghum poles, and dry them on the roof. Because the dates are harvested in autumn, the sun is not particularly scorching, so they have to be dried for more than ten days to a month or two months.

There are four things to note:

1. The fire of boiling water should be strong, and the fire should be strong, so that the water for boiling the dates will be boiled quickly, or the dates will not be fresh if they are not soaked for a long time;

2. The mat for drying dates should not be spread on the ground, but should be supported underneath and the mat should be elevated to ensure its air permeability;

3. The dried dates should be turned over from time to time to dry evenly;

4. It is necessary to boil the water to scald, this process kills some germs and makes the dates not easy to rot.

1. The first thing to do is to choose the date of picking fresh jujubes from a good source, and pick them when the red fruits of the jujube reach more than 25% coloring, and the jujubes at this stage are the most resistant to storage.

2. Choose a good picking date and then select the fruit varieties, generally speaking, the late-maturing varieties are more resistant to storage, and do a good job of choosing winter dates.

3. The fresh jujubes picked should also be selected, and the bad jujubes with bruises and black spots and insects on the surface should be selected to avoid the bad jujubes with mold during the storage period from infecting other jujubes and affecting the storage.

4. The preservation of fresh jujube is generally refrigerated, and the pre-stored fresh jujube should be pre-cooled at a temperature of 5-8 for one or two days before refrigeration. Before pre-cooling, fresh dates should be soaked in a solution of 2% calcium chloride for 30 minutes.

5. After pre-cooling, the fresh jujube should be stored in a cold storage with a temperature of 0 1 and a relative temperature of 90% and 95%.

Use the vacuum packaging method. Use an airtight food bag to fill fresh dates, use a vacuum packaging machine (sold in the market for household use) or use a vacuum cupping device to extract the air in the bag and seal it. Food bag sealers are also available, which are very cheap, or can be sealed with a saw blade heating method.

Freshly picked dates are stored in the refrigerator.

The method of preserving fresh jujube is generally used in 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, leaving a small amount of air in the bag, and then sealed well, and then put it in the refrigerator at 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.
