Method for making black jujube {Method for making the black jujube}

The present invention relates to a method for producing black jujube, and more particularly, the washed jujube is impregnated in a fermentation broth mixed with sterilized water and makgeolli, and the jujube is dried after fermentation of the jujube infiltrated with fermentation broth and then steamed and dried. The fermentation of black jujube (blackening) increases the beneficial weakness contained in the jujube as well as the increase in sugar content to satisfy the various tastes of modern people, to provide a black jujube that can prevent the loss of water-soluble nutrients will be.

In general, since jujube contains components such as sugar, organic acid, mucus, dietary fiber, minerals, flavonoids, and cyclic AMP, they are widely used as ingredients for herbal medicine or other dishes.

However, since the jujube itself has a lot of moisture and various enzymes, the storage property is very weak, the color is easy to change, and the sticky and tough nature when edible has many problems.

In particular, when the dates are dried, the seeds and the pulp are in close contact with each other, making it difficult to separate, making the shells coarse and thick, making it more difficult to eat.

In order to solve this drawback, the manufacturing method of dried jujube of Patent Publication No. 1978-621 is steamed for 2 hours or more by steam to uniformly and stably heat-treated, killing various germs, sugar, salt in the steamed jujube The technique of producing dried jujube with water content of 12% by adding the back is proposed.

However, in the method, the sugar content of the jujube itself is diluted in the steaming process, and thus, an additional flavoring process, such as sugar, is required, and it is difficult to dry the deep part of the jujube.

As a prior art to solve this problem, the Republic of Korea Patent No. 10-0647426 in order to remove the seeds of the jujube and slice (slice) to facilitate drying, and to maximize the sweetness of the jujube itself without a separate flavoring process 6 Techniques for providing sliced jujubes with moisture content of up to% have been proposed.

Looking at the method of producing a sliced jujube in the above-described prior art in detail, after carefully selected dry jujube of a relatively uniform length, washed with 0.7ppm ozone water with sterilizing power, the seed is removed, sliced, 50 ~ 60 After hot air drying for about 5 ~ 6 hours in hot air drying room at ℃, and slowly aging for 20 ~ 28 hours in refrigerated warehouse keeping at 0 ~ 5 ℃, the water content increases to 6% or less and the sugar content is the highest. And sliced jujube ripened slightly softer.

However, the hot air drying and low temperature aging method maintains the crispness as the moisture content is increased from 4% or less to 6% or less, but it cannot satisfy the desire of consumers for a more crispy taste, and also 50 to 60 ° C. Since the jujube is processed directly at the temperature of, the water-soluble nutrients contained in the jujube are dissolved in the moisture contained in the jujube during the drying process and evaporate with the water, thereby causing a loss of nutrients.

In addition, the moisture evaporates while drying at a temperature of 50 ~ 60 ℃ and in this process the pulp is broken, the volume is reduced, and a lot of time and time to slice and slice the small jujube thin slices There was a problem that the manufacturing cost of the product is increased due to the cost of work.

And, if red ginseng or black garlic of ginseng, each of the ginseng and garlic is fermented in the process of fermenting beneficial weakness to the human body contained in them, the conventional invention in the red ginseng or garlic Since there is no fermentation process of black jujube, such as black garlic, there was a pity that the beneficial weakness of jujube could not be maximized.

Patent Publication No. 10-1978-621 (Name of invention: Preparation of dried jujube) Patent registration No. 10-647426 (name of the invention: slice jujube and its manufacturing method)

The present invention is to solve the above problems, impregnated with the washed jujube in the fermentation broth mixed with sterilized water and makgeolli, dried after fermentation of the jujube infiltrated with fermentation broth and then steamed and dried as the jujube fermented It is a technical task to provide black jujube that can be blackened to increase the beneficial weakness contained in jujube and sugar content to satisfy various tastes of modern people and to prevent loss of water-soluble nutrients. do.

The present invention washes the selected jujube with clean water and then supports the jujube to remove the water on the outer surface of the jujube, and the sterilized water and makgeolli after boiling the water mixed in a ratio of 5: 5 fermentation broth Prepare the fermentation broth prepared and the fermentation broth mixed with sterilized water and makgeolli for 5 to 10 minutes after immersing the jujube in the fermentation broth for 5 to 10 minutes. Jujube fermentation step to soak for 5 to 10 minutes and take it out to the outside and keep it sealed for 24 hours to ferment the jujube into the jujube, and the jujube fermentation step through the jujube impregnation step at a temperature of 35-40 ° C. for 24 hours. , The drying step of drying the jujube through the fermentation step of the jujube 20 ~ 30%, and put the jujube through the jujube fermentation step into the steamer at 80 ~ 85 ℃ Jujube steaming step of steaming while heating to 50-55 hours at temperature, and steamed jujube drying step of taking out the black jujube through the jujube steaming step from the steamer and naturally drying at room temperature for 24 to 25 hours in the shade .

As described above, the method of manufacturing black jujube of the present invention is impregnated with the washed jujube in a fermentation broth mixed with sterilized water and makgeolli, followed by fermentation of the jujube infiltrated with fermentation broth, followed by steaming and drying. During fermentation, blackening (blackening) increases the weakness (sugar, organic acid, mucus, dietary fiber, minerals, flavonoids, cyclic AMP, etc.) contained in jujube, and the sugar content increases to meet the taste of modern people. In addition to providing black jujube, there is an effect to provide a black jujube to prevent the loss of water-soluble nutrients.

1 is a process flow diagram of a black jujube manufacturing method according to the present invention.

Hereinafter, the black jujube manufacturing method according to the present invention will be described with reference to the accompanying drawings.

The present invention is a jujube washing step 101 to wash the selected jujube as shown in Figure 1, fermentation broth manufacturing step 102 of mixing the sterilized water and makgeolli in a ratio of 5: 5, and jujube impregnated with the jujube Impregnation step 103, jujube fermentation step 104 to ferment the jujube infiltrated with fermentation broth, drying step 105 to dry the fermented jujube, and jujube steaming step to steam the fermented and dried jujube (106) ), And steamed jujube drying step 107 for drying the steamed jujube.

The jujube washing step 101 is a process of extracting the water buried in the outer surface of the jujube by supporting the jujube washed with clean water on the tray.

The following fermentation broth manufacturing step 102 is to prepare a fermentation broth by mixing sterilized water and makgeolli obtained by boiling after cooling to a ratio of 5: 5, it is possible to obtain sterilized water by boiling water.

The temperature of boiling water to obtain sterilized water as above is preferably boiled for 5 to 10 minutes. When the water is boiled for 5 to 10 minutes, the E. coli and general bacteria contained in the water are sterilized and the water is 20 to 30 minutes. When boiled, volatile organic substances and phenols contained in water are volatilized and removed, and pesticides are removed by boiling for 20 to 30 minutes.

It is preferable to boil water for 5-10 minutes in order to obtain sterilized water. When using tap water with purified water, volatile organic substances, phenols and pesticides Of course, because it is clean water that does not contain E. coli and bacteria, even if you boil for 5 to 10 minutes, you can sterilize any bacteria that may be present.

Mixing the sterilized water and makgeolli in a ratio of 5: 5 in the fermentation broth manufacturing step 102, the fermentation of jujube is made when the content of makgeolli in the fermentation broth prepared by mixing makgeolli and sterilized water is 45-55% by weight. When the content of makgeolli is 55-60% by weight, the final production of black jujube produces odor of makgeolli, and it is preferable to mix sterilized water and makgeolli at a ratio of 5: 5.

The following is a description of the jujube impregnation step 103, which is immersed in the fermentation broth mixed with sterilized water and makgeolli in the jujube washing step (101) and drained jujube, wherein the jujube is soaked in the fermentation broth 5 ~ Soak for 10 minutes.

Applicant of the present invention soaked 600 grams of jujube for 5-10 minutes in 2 liters of fermentation broth, and then the jujube was removed from the fermentation broth and stored in a sealed container for 24 hours, the fermentation broth was buried on the outer surface of the jujube It will seep into the interior of the.

After the fermentation broth is first absorbed into the jujube in the sealed container as above, the jujube is immersed in the fermentation broth again for 5 to 10 minutes, and then the jujube is sealed and sealed for 24 hours in a sealed container. To be absorbed.

After finishing the jujube impregnation step 103 as described above is to run the jujube fermentation step 104, the jujube fermentation step 104 is finished jujube impregnation step 103 to the temperature of 35 ~ 40 ℃ the jujube penetrated After fermentation in a fermentation chamber for 24 hours.

At this time, the fermentation is made by the fermentation ingredients contained in the makgeolli, the weakness of the jujube in the process of fermentation is improved.

This is the same principle that if ginseng is produced with red ginseng, saponin and other beneficial weakness is increased, and allicin is increased when garlic is blackened.

As the jujube through the jujube fermentation step 104 as described above is in a wet state containing a large amount of water, the fermented jujube may be released in a steaming step to be performed later, and thus, a drying step for preserving the shape of the jujube (105) Additional).

The drying step 105 is a natural drying or hot air drying so that the moisture content of the jujube through the jujube fermentation step 104 is 20 to 30%, the applicant of the present invention is carried out jujube through the jujube fermentation step 104 In the state supported by, keep for 1 to 2 days at room temperature and reveals that the natural drying.

As you go through the drying step 105 as above, the soybeans that have been tingled are pinched, so that the jujube is not released in the steaming process to be carried out later, so that the form can be maintained.

After passing through the drying step 105 as above, the jujube steaming step 106 is executed, and the jujube steaming step 106 is a fermented and dried jujube in a steamer at a temperature of 80-85 ° C. for 50-55 hours. When steamed while heating, the jujube will turn black.

At this time, if steaming temperature is steamed within 80 hours at 80 ~ 85 ℃, the color of jujube does not change to completely black but becomes blackish brown, making it difficult to manufacture perfect black jujube, but steaming temperature is 50 ~ 55 at 80 ~ 85 ℃. Steaming time increases the sugar content as the jujube turns completely black.

Black jujube through the jujube steaming step 106 as described above is carried out steam drying jujube drying step 107 to be taken out from the steamer after drying, at room temperature for 48 to 50 hours, or using a dryer 35 ~ 45 ℃ Drying at a temperature of 24 to 25 hours to complete the manufacture of black jujube.

The black jujube prepared by the manufacturing method as described above has the effect of increasing the beneficial weakness to the human body contained in the jujube as the color changes during the aging process by fermentation and steaming, such as red ginseng or black garlic, Black jujube is chewy and sweet and you can enjoy black jujube deliciously.
