Red ginseng is a ginseng that is selected from the good quality 6 year old root ginseng produced in the cultivation area of ginseng and is dried with steam for a long time without peeling and dried. These red ginseng produce various new physiologically active ingredients that are good for our body in the manufacturing process.

Especially, the chemical structure of ginsenoside, which plays a major pharmacological role of ginseng in red ginseng manufacturing process, changes. At this time, components such as anti-cancer component, anti-diabetic component, anti-inflammatory component, antioxidant component, liver function detoxification component and heavy metal detoxification component, which are not present in the ginseng and content is extremely small, may be newly generated or increased.

These ginsenosides are classified into three classes depending on the chemical structure: protopanaxadiol, protopanaxatriol, and oleanolic acid. Ginseng contains 34 kinds of ginsenosides (22 kinds of white ginseng, 30 kinds of red ginseng), and various kinds of ginsenosides have a wide effect on the central nervous system, endocrine system, immune system, metabolism system, It has been confirmed that it exerts an excellent effect in normalizing the physiological function. In particular, it is specified that Rg1 and Rb1 among the ginsenosides possessed by ginseng should be contained in the range of 0.8 to 34 mg / g in total of the ginsenosides Rg1 and Rb1 designated as functional components, i.e., index components, , Which is classified as a high-quality product in which the sum of Rb1, Rg1 and Rg3 is 3 mg or more.

The red ginseng concentrate refers to a product obtained by boiling steamed ginseng with steam or other methods, and extracting and filtering the dried red ginseng component from the dried red ginseng as a mixture of water, alcohol, or a mixture of water and alcohol. As a result, packaging methods have been diversified to satisfy consumers' preferences.

In particular, red ginseng concentrate products packed in a pouch-type packaging material are also being marketed so that the red ginseng concentrate can be easily ingested. When such a red ginseng concentrate should be able to be easily handled, I can not take advantage of it.

Conventionally, in order to complete a pouch-type red ginseng concentrate product, water is mixed with a concentrate at a high concentration and diluted to a proper concentration. Therefore, the production method is complicated and the content of ginsenosides Rg1, Rb1 and Rg3 There was a problem that it was deteriorated.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a method for preparing a red ginseng concentrate having a proper solid content for easy eating and drinking, and especially a ginsenoside Rg3 content.

According to an aspect of the present invention, there is provided a method for producing red ginseng, comprising: a first step of introducing red ginseng raw material and purified water into an extractor; A second step of circulating the charged red ginseng raw material and purified water at 75 ° C to 85 ° C for 6 hours or longer to produce red ginseng extract; A third step of separating the prepared red ginseng extract through a filter; A fourth step of cooling the separated red ginseng extract; And a fifth step of concentrating and transferring the cooled ginseng extract to a storage part. The process of the first to fifth steps is repeated one or more times for the remaining red ginseng material after the third step of separating the red ginseng extract , And the ratio of the red ginseng raw material and the purified water introduced in the first step corresponds to 1:10 to 1:12 (g: mL).

According to one embodiment, the processes of the first to fifth steps repeated for the red ginseng raw material remaining after the separation of the red ginseng extract in the third step may be repeated four times.

According to one embodiment, the concentration of the red ginseng extract in the fifth step may be performed under a vacuum of 60 ° C or lower.

According to one embodiment, the concentration of the red ginseng extract in the fifth step may be set to a solid content of 25% to 35%.

The invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It should be understood that the drawings and embodiments are not intended to limit the scope of the present invention.

Hereinafter, the present invention will be described in detail.

How to make red ginseng concentrate

The overall process of the present invention will be roughly described with reference to Fig.

1 shows a flow chart of a method for producing a red ginseng concentrate according to the present invention.

First, red ginseng raw material and purified water are introduced into an extractor and circulated at 75 ° C to 85 ° C for 6 hours or more to produce a red ginseng extract. The red ginseng extract is then separated, cooled, and then concentrated to complete a red ginseng concentrate .

At this time, after the red ginseng extract is separated, the extraction process may be repeated for the remaining red ginseng raw material.

Thus, according to the present invention, there is provided a method for producing red ginseng, comprising: a first step of feeding red ginseng raw material and purified water into an extractor; A second step of circulating the charged red ginseng raw material and purified water at 75 ° C to 85 ° C for 6 hours or longer to produce red ginseng extract; A third step of separating the prepared red ginseng extract through a filter; A fourth step of cooling the separated red ginseng extract; And a fifth step of concentrating and transferring the cooled ginseng extract to a storage part. The process of the first to fifth steps is repeated one or more times for the remaining red ginseng material after the third step of separating the red ginseng extract , And the ratio of the red ginseng raw material and the purified water introduced in the first step corresponds to 1:10 to 1:12 (g: mL).

As used herein, the term " red ginseng raw material " refers to red ginseng dried by steaming fresh ginseng, and the origin, type and form of ginseng is not limited. That is, the red ginseng raw material may be processed into a powder form in order to more efficiently carry out the extraction process, or the red ginseng raw material, which is a mixture of red ginseng and red ginseng, have. Considering the content and the ratio of ginsenoside contained in the red ginseng extract, it is preferable that the red ginseng and red ginseng have a weight ratio of 7: 3.

The raw material of red ginseng is added to an extractor together with purified water, and a red ginseng concentrate product which can be ready for eating can be prepared by using purified water. In addition to purified water, when preparing a red ginseng extract using a solvent such as alcohol, the step is required to evaporate the solvent separately. Thus, the process becomes complicated, and the trace ginsenoside useful for the human body is destroyed or reduced by various chemical components such as an alcohol component .

As used herein, the term " red ginseng extract " refers to a solvent in which the active ingredient contained in red ginseng has been transferred by contacting the solvent and red gins under specific conditions, and the type of the solvent is not particularly limited. In the present invention, Similarly, purified water is used for the production of red ginseng extract.

Therefore, the process of preparing the red ginseng concentrate can be simplified through the extraction process using purified water, and the content of Rg3, which is one of the trace ginsenosides, is not lowered and can be abundantly contained.

At this time, the ratio of the red ginseng raw material and the purified water to be added may correspond to 1:10 to 1:12 (g: mL), preferably 1:12 (g: mL).

The red ginseng extract may be prepared by circulating the charged red ginseng raw material and purified water at 75 ° C to 85 ° C for 6 hours or more, preferably for 8 hours.

In other words, red ginseng concentrate should have a proper concentration for easy food intake. Therefore, when the ratio of purified water is less than 1:10 (g: mL), the concentration of the extract is increased and the viscosity is increased. : 12 (g: mL), the content of the red ginseng component may be below the reference value, and the concentration may be too low to allow excessive time for the concentration process.

The red ginseng raw material is heated for a predetermined time together with the purified water, whereby the active ingredient contained in the red ginseng raw material is extracted as purified water.

However, when acid treatment, high-temperature treatment or long-term processing conditions are applied in the extraction process of red ginseng, ginsenosides Rg1 and Rb1, which are the unique pharmacological components contained in ginseng, are destroyed, On the other hand, temperature and time may be important parameters in the extraction process, since the process yield may be significantly lowered when the ginsenosides are preserved and the low temperature treatment or the treatment time is shortened to maintain the original taste and aroma .

Therefore, it is preferable to carry out the extraction process in consideration of the temperature range and time so that the extraction of the active ingredient contained in red ginseng can be smoothly performed.

Next, the red ginseng extract is separated through a filter.

The pore diameter of the filtration filter is 80 to 120 탆, and it may be three-pore.

Red ginseng raw material added with purified water can be separated from red ginseng extract through filtration filter. The red ginseng extract, which has passed through the filter, can be transferred to a separate reservoir for continuous subsequent cooling.

Here, the term " storage unit " means a specific place or apparatus for storing a raw material or various additives in a conventional process for a certain period of time, and its meaning is not particularly limited as long as it can perform such a function.

The pore diameter of the filtration filter is preferably 80 to 120 탆 as described above, and impurities contained in the red ginseng extract can be suitably removed by constituting the filter in triplicate. If the pore diameter of the filtration filter is 120 탆 or more, the red ginseng extract may contain impurities excessively and the texture of the product may be deteriorated. If the pore diameter is 80 탆 or less, the filtration process may not be efficiently performed.

Then, the separated ginseng extract may be cooled at a low temperature. The cooling method and the cooling temperature are not particularly limited, but cooling can be preferably performed at 15 to 25 캜.

The impurities contained in the cooled red ginseng extract can be filtered again through a centrifuge.

That is, although the impurities are primarily removed through the filter, it may contain fine impurities that can pass through the pores. Therefore, the impurities are secondly removed through the centrifuge.

Considering time and cost, the number of revolutions of the centrifugal separator for filtering the impurities is preferably 8000 to 9000 rpm.

Fine impurities contained in the concentrate may form precipitates at the bottom of the liquid over time, which may adversely affect the quality of the product.

Thus, by removing the impurities again as described above, the texture of the red ginseng concentrate product can be further improved, and the quality of the product can be improved by minimizing the amount of the precipitate, thereby satisfying consumers' preferences.

Next, the cooled ginseng extract is concentrated and transferred to a storage section.

Concentration of the red ginseng extract may be performed under a vacuum of 60 ° C or lower.

As used herein, the term " thickening " refers to an operation of removing moisture to increase the concentration of solid matter, and the method of concentration is not particularly limited, and includes evaporation to evaporate water, freezing the water as a solvent, , And reverse osmosis concentration in which water is separated through a semipermeable membrane by applying a pressure equal to or higher than osmotic pressure of the concentrate may be used, but a method of concentrating the evaporation can be used.

In particular, since the active ingredient contained in the red ginseng extract may be deformed or destroyed at a high temperature, it is preferable to control the temperature at an appropriate level in proceeding the process. For this purpose, The concentration method can be used.

By evaporating water in a vacuum state, the red ginseng extract can be concentrated at a relatively low temperature. However, when the temperature is excessively lowered, the evaporation of water does not smoothly occur and the efficiency of the whole process may be lowered. The temperature can be adjusted appropriately.

The concentration of the red ginseng extract may be a solid content of 25% to 35%, preferably a solid content of 30%.

As used herein, the term " solid content " refers to the solid red ginseng component remaining when the water is completely removed from the red ginseng extract. The higher the concentration, the higher the solid content and thus the viscosity of the red ginseng extract may be increased.

Since the viscosity of red ginseng extract may affect the easiness of taking in red ginseng extract, the red ginseng extract prepared according to the present invention is set to be most optimized for direct intake.

When the solid content is less than 25%, the concentration of the ginsenoside contained in the red ginseng extract may be insufficient because the concentration thereof is diluted. In addition, when the solid content is more than 35%, the viscosity may be high and the ease of taking may be deteriorated. In particular, when used as a pouch-type red ginseng beverage, which is required to be easily consumed, the commerciality may be lowered.

Next, the red ginseng extract may be separated and the extraction and concentration process may be repeated for the remaining red ginseng material.

That is, even if the extraction process for red ginseng is terminated, various effective ingredients including ginsenoside contained in red ginseng may not be completely extracted by a single process.

In this case, the mixing ratio of the remaining red ginseng raw material and purified water is 1:10 (g: mL), unlike the initial process. In this case, .

Since a certain amount of the active ingredient contained in red ginseng is extracted through the first extraction process, the extraction process can be more effectively performed by reducing the amount of purified water in the repeated extraction process.

The extraction and concentration process for the remaining red ginseng raw material may be repeated four times in consideration of time and cost.

That is, even if the extraction step is repeated, since there are not many active ingredients contained in red ginseng, the further extraction step may be meaningless in consideration of the production efficiency.

As described above, the red ginseng extract extracted and concentrated through each process is transferred to the storage part by proceeding the extraction step one or more times, and the red ginseng extract collected in the storage part is red ginseng concentrate having an appropriate solid content concentration do.

In particular, as described above, the red ginseng concentrate has a solid concentration suitable for pouch-packed red ginseng concentrate products, and it has been found that when the solid content of the red ginseng concentrate is about 30%, the most excellent product is obtained through repeated experiment and evaluation.

Therefore, the red ginseng concentrate prepared through the above-described method can be selectively sterilized and then packed in a pouch-shaped packaging material to be a final product.

Since the ginsenoside component contained in the red ginseng concentrate may be destroyed or deformed when the germicidal composition is sterilized at an excessively high temperature, Lt; / RTI >

After the extraction process was completed, the filtration filter having a pore diameter of 100 μm was composed of triplet, and the extract was separated by filtration. The separated red ginseng extract was cooled at 20 ° C. Subsequently, the cooled ginseng extract was secondly filtered using a centrifuge at a rotation speed of 8,400 rpm, transferred to a vacuum concentrator, concentrated to have a solid content of 30% at 50 ° C, and transferred to a storage tank.

Next, the red ginseng extract was separated and the remaining red ginseng material was charged with 10 times of purified water (3,437,500 mL), and the above process was repeated in the same manner four times.
