How to make jujubes and how are jujubes made?

Preparation of red dates:1. Raw material selection: Fruits with fresh and ripe, large fruit shape (excellent jujube varieties can also be selected), thin skin, thick and dense flesh, high sugar content and small kernel should be selected.

2. Pick out wind-falling jujubes, diseased and broken jujubes.

3. Grading: Remove litter and leaves, grade according to variety, size and maturity, and the degree of dryness is consistent.

4. Blanching: Put the jujube fruit into a bamboo basket or wire basket, soak the basket in boiling water, blanch for about 5 minutes, and the peel is slightly soft. Cool in cold water immediately after blanching.

5. Drying: There are two kinds of drying: natural drying and artificial drying.

Drunken jujube: 1. Raw materials.

10 kg of fresh jujubes, 1 kg of high grain liquor, about 1 kg of liquor, and about kg of liquor, according to this proportion.

Second, the key points of operation.

1. Raw material requirements: First, pick dates, do not beat dates with sticks. Or shake the branches of the jujube tree, and lay soft underlayments (such as straw curtains, mats, plastic sheets, etc.) on the ground to prevent contamination by external injuries and miscellaneous bacteria, and internal injuries form agglomerations.

Second, to prevent transportation pollution and injury, if the old sack is used for transportation, it must be cleaned, dried and reused.

2. Material selection: It can be divided into two picking periods, and the agricultural proverb in North China has the saying that "July 15 red circle, August 15 (harvest)". The fifteenth day of the seventh month of the lunar calendar is roughly equivalent to September 10-15 of the Gregorian calendar, and the "red circle" refers to the fact that in this period, there are roughly 1 3 fresh jujube fruit stalks around the outer edge of the fruit stalk turning red, 1 3 in the milky white stage, and the other 1 3 is still hanging green.

In this period, red circle jujubes and fresh jujubes that are about to turn red in the later stage of milky white should be selected. The red circle is followed by a gradual red color. In both periods, it is necessary to choose fresh jujube with no internal and external injuries, no diseases and pests, full jujube fruits, uniform and not soft.

3. Cleaning and air drying: The selected jujube fruits are rinsed with flowing water, spread on the mat, and the skin moisture is removed for later use.

4. Shabu-shabu: Put the fresh jujube that has been dried out of the floating water into the wine in batches according to the ratio of 10:1 between the jujube and the wine, and take it out, and the body of the shabu-shabu is required to be clear as before.

5. Into the cylinder: Put the shabu jujube into the jar that has been washed and dried in advance, cover the cylinder mouth with a layer of thick kraft paper, tie it tightly, and then cover it with a double layer of plastic cloth and then tie it tightly, and seal it tightly, do not leak air, and the jujube can be drunk in 15 days. Then it can be out of the cylinder (remove individual wounded dates, bad dates), and vacuum packed with polypropylene plastic film, and the finished product is boxed into the box.

Jujube is made from fully ripe fresh jujube, which is the dried product with the largest processing capacity, the simplest method and the most widely used jujube in China.

1. The drying methods mainly include drying method, sun-drying method, baking method and dryer drying method. In addition, in recent years, new methods such as freeze sublimation drying method, microwave drying method, far infrared drying method, and solar drying method have been newly developed. Either way, the fresh dates used should be harvested and graded when they are fully ripe.

To improve quality, blanch in boiling water for 5 to 10 minutes before drying.

2. Drying method: Dry the fresh jujube in a dry and ventilated place in the shade, and turn it once every 1 3 days to make the jujube gradually lose water and become a dried 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.

3. Sun-drying method: choose a dry, flat and ventilated place to set up a drying field, spread it on the brick with sorghum stalks, and branch it 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.

Fresh jujube is reduced from about 70% water content to about 25%, so that the concentration of soluble solids is increased to the extent that it is difficult for microorganisms to survive and utilize.

Dried jujube does not use the sun's drying, this method is extremely inefficient, and it is not easy to preserve, and now the developed technology is used to dry jujube. There are four techniques for drying jujubes:

1.Hot air drying technology uses a heat source to provide heat to heat the air in the drying chamber, so that there is a temperature difference between the materials and the air around the materials, so that the moisture inside the materials evaporates due to the temperature gradient, so as to achieve the purpose of drying.

2.Microwave drying technology, microwave is an electromagnetic wave, which has both mechanical energy carried by particles, as well as electric field energy and magnetic field energy. When the polarity direction of the electric field is constantly changing, the polar molecules in the raw material move at high speed and generate frictional heat, so that the surface and interior of the substance are heated at the same time to achieve the purpose of drying.

3.Vacuum freeze drying, the aqueous material is cooled and frozen in advance, and then the ice crystals are directly sublimated into water vapor at the appropriate temperature (45 55) and high vacuum degree to remove the moisture inside the material.

4.Solar drying refers to the drying industry carried out by using solar radiation energy and solar drying devices.

The method of making dried red dates is as follows:

Tools Raw materials.

Red dates, water. 1. Be sure to choose a jujube that is fully ripe, with a reddish heart and a moderate size; Don't have worms; You can choose whether to go to the nucleus or not according to your hobbies.

2. Then boil it in boiling water for a few minutes, then use a tool to immediately pick it up and put it in cold water to cool it. (How long you need to cook depends on what kind of jujube it is, generally five or six minutes is appropriate).

3. Spread the jujube evenly, expose it to the sun for 3 or 4 days, turn it frequently during the exposure process, and it is best to spread the thatch on it at night, so as not to get wet.

4. Diagram of dried jujube finished products.

Ingredients: 40 large red dates.

2. Use a straw to core the jujubes, and the straw used to drink yogurt is the most suitable.

3. Perfect separation of the pits.

4. Cut the jujube into sections, and it is almost the same to cut 4-5 sections of a jujube.

5. After that, put the jujube segments into the air fryer or oven with hot air function.

6. Then bake at a low temperature of 120 degrees for about 35 minutes. The oven lasts longer, about forty minutes. Freshly roasted red dates are still a little soft, and they will become crispy when cooled.

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

In the sun, the red dates are all dried. The method of drying with a dryer is too expensive. (In the process of drying, it should be turned often, otherwise the bottom is easy to rot.) ）

Hello: Steps.

1 Ingredients: Fresh jujubes.

2. Prepare the gauze for drying jujubes.

3Put the jujube on a gauze and place it in a sunny place.

4. Put a layer of gauze on top of the jujube (for fly prevention).

5. Put the dried jujube in the box after more than 20 days.

6. Pick out the bad jujubes, put the good ones in a breathable mesh bag and store them in a cool place.

Tip 1: Be sure to dry in the sun.

2. Store in a cool place.

Hope it helps!
