Description

Ginseng processing method and ginseng processed product manufactured by the same method {Manufacturing method for processed ginseng and processed ginseng by the same}

The present invention relates to a method for processing ginseng and a processed ginseng product manufactured by the method.

Ginseng has been known since ancient times to have various effects, such as fatigue recovery and strengthening immunity, and is consumed in various processed forms, such as red ginseng, white ginseng, and black ginseng. These effects of ginseng have been revealed to be due to the saponin contained in ginseng, and recently, many studies have been conducted to increase the efficiency of extracting saponin.

There are several methods for extracting saponins, including ultrasonic extraction, which extracts by applying ultrasonic waves; ultrasonic wave extraction, which extracts by applying ultrasonic waves; and solvent extraction, which extracts by soaking ginseng in a solvent such as alcohol. Extracts extracted by these methods have a very high concentration of saponins and other components are also highly concentrated, so direct ingestion may cause side effects such as increased blood pressure and indigestion.

Accordingly, in the related business field, a method of processing ginseng by steaming or heating it into a form that can be directly consumed, such as red ginseng or white ginseng, is widely used. Prior art document, Korean Patent No. 10-2074810, discloses a technique for preventing nutritional loss and increasing the content of ginsenoside (a type of saponin) by fumigating ginseng with sulfur.

Figure 1 is a flow chart of a ginseng processing method according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. In addition, the embodiments of the present invention are provided to more completely explain the present invention to a person having average knowledge in the relevant technical field. Therefore, the shapes and sizes of the elements in the drawings may be exaggerated for clearer explanation, and elements indicated by the same reference numerals in the drawings are the same elements. In addition, the same reference numerals are used throughout the drawings for parts having similar functions and actions. In addition, throughout the specification, the term "including" a certain element does not exclude other elements unless specifically stated otherwise, but means that other elements can be further included.

A method for processing ginseng according to an embodiment of the present invention comprises the steps of heating ginseng at a temperature of 70 to 90° C. at 1.2 to 2 atmospheres (atm); and drying the heated ginseng.

The method may further include a step of pre-treating ginseng before performing the method. The pre-treatment may include processes such as washing and handling of ginseng. In an embodiment of the present invention, ginseng may be processed with the fine roots attached, but may be processed after removing the fine roots or cutting them to an appropriate size, if necessary. Such pre-treatment is not particularly limited as long as it is generally performed in the relevant field.

The step of heating the ginseng above is a step for increasing the content of soluble saponin contained in the ginseng. By performing this step at a pressure higher than atmospheric pressure, the humidity in the air can be prevented from becoming too high, which can increase the moisture content of the ginseng too much, and the effective ingredients can be prevented from evaporating from the ginseng.

This step can be performed at a pressure of 1.2 to 2.3 atm, preferably 1.8 to 2.3 atm, and more preferably 2.1 to 2.3 atm. The temperature condition of this step can be 70 to 90°C, and can be performed for 5 to 20 hours, preferably 10 to 15 hours. If the pressure or temperature is too high, there is a problem that the effective ingredients contained in ginseng are destroyed, and if the pressure or temperature is too low, the effect of increasing saponin is minimal.

The ginseng used in this step may have a moisture content of 50 to 70%, preferably 60 to 70%. If dried ginseng is used, the fine roots of the ginseng may be damaged even at low temperatures, and the fine roots and part of the surface of the ginseng may burn. Therefore, in the embodiment of the present invention, it is preferable to use ginseng having a moisture content of 50% or more. In the case of dried ginseng, it is necessary to adjust the moisture content to 50%, preferably 60% or more through pretreatment.

This step can be performed by placing water and ginseng in a container that can be sealed from the outside and controlling the pressure while heating the container. At this time, by placing the ginseng apart from the water so that it does not come into contact with it, the active ingredients of the ginseng can be prevented from being released by the heated water.

Heating and pressure control can be done by methods commonly used in the field and are not particularly limited. For example, the container may be connected to a pressure regulator, and the pressure can be controlled by injecting compressed air or exhausting the air inside.

The above step of drying ginseng is a step that increases the effective ingredients inside ginseng and at the same time removes moisture to increase the storage properties. In this step, 10 wt% of the moisture contained in ginseng can be removed.

This stage can be divided into a first drying stage in which rapid drying is performed in a dryer and a second drying stage in which natural drying is performed at room temperature.

The above first drying step may be to provide warm air using a heater or to quickly remove moisture contained in the ginseng using a lamp. However, even at this time, the temperature of the ginseng should be maintained below 70℃ to solve the problem of the fine roots of the ginseng being burned or the moisture being rapidly removed only in a part, resulting in uneven quality. In addition, a process of sterilizing the surface of the ginseng using a UV lamp, etc. may be additionally performed at this step. This can remove mold, fungi, etc., enabling long-term storage. In this step, it is preferable to have the moisture contained in the ginseng be 5 to 15% to increase the storability.

The above second drying step can dry the ginseng at room temperature without direct sunlight, and can be performed by a natural drying method commonly used in the field. This step can be performed over several weeks or several months, and preferably can be performed for one month. The moisture content of the ginseng in this step can be 3 to 10 wt%.

In one embodiment, the step of maturing the dried ginseng may be further included. Maturing is performed by maintaining the dried ginseng at a sub-zero temperature for a long period of time to increase the content of effective ingredients within the ginseng.

This step can be performed under conditions of 0℃ to -5℃, and can be performed for 6 to 24 months, preferably 12 to 18 months. If the temperature is too low, the ginseng tissue may be damaged, resulting in the production of undesirable components and a decrease in quality, and if the temperature is high, there is no increase in the effective components due to low-temperature maturation.

Next, a step of putting ginseng in water and heating it to extract it can be performed. The extraction method is not particularly limited, and can be performed by putting ginseng and water in an extractor commonly used in the field. This step can heat water to a temperature of 70 to 90℃ under 0.5 atm.

Next, a step of concentrating the extract may be further included. The concentration method is not particularly limited, and can be performed using a concentrator generally used in the relevant field.

Example 1

Five-year-old ginseng with a trunk length of 10 to 13 cm and a weight of 70 to 90 g was taken and washed. The washed ginseng was placed on a tray of a heater, water was added to the inner container of the heater, and the heated ginseng was maintained at 85℃ and 1.8 atm for 12 hours. The heated ginseng was placed in an ultraviolet sterilizing dryer and dried until its weight reached 50% of the initial weight. Next, the dried ginseng was placed in a warehouse and naturally dried at room temperature for 30 days. Next, the naturally dried ginseng was placed in a freezer and aged at -2℃ for 12 months.

Example 2

Example 1 was performed in the same manner as Example 1, except that the pressure conditions in the heating process were maintained at 2.2 atm.

Comparison Example 1

The same procedure as Example 1 was followed, except that ginseng that was 10 to 13 cm long and 70 to 90 g in weight among 5-year-old ginseng was used, dried in a dryer, and had its moisture removed to 40 to 50 g, which is less than 60% of its initial weight.

Comparison Example 2

The same procedure as Example 1 was performed, except that the pressure was maintained at atmospheric pressure during the heating process.

Comparative Example 3

The same procedure as Example 1 was followed, except that the pressure was maintained at 2.5 atm during the heating process.

Comparative Example 4

The maturation process was performed in the same manner as in Example 1, except that it was performed at room temperature.

Experimental example: Saponin content test

The saponin content of the examples and comparative examples was investigated and is shown in Table 1. It can be seen that the content of Rg3 is high in examples 1 and 2, which underwent a heating process under pressure and underwent low-temperature maturation.

division Rb1 content (mg/g) Rg1 content (mg/g) Rg3 content (mg/g) Example 1 5.85 0.52 2.95 Example 2 5.34 0.48 3.34 Comparison Example 1 5.43 0.83 1.53 Comparison Example 2 5.35 0.72 1.98 Comparative Example 3 5.51 0.87 2.25 Comparative Example 4 5.83 0.61 2.37

Experimental Example: Sensory Testing

The Examples and Comparative Examples were consumed by 23 adults, and the degree of bitterness was described in comparison with Example 1. If the bitterness was slightly stronger than Example 1, +1 point was given, if it was much stronger, +2 points were given, if it was weaker, -1 point, if it was much weaker, -2 points were given, and if it was the same, 0 points were given. Table 2 shows the average of the results. Referring to Table 2, it can be seen that the bitterness was improved in the Examples and Comparative Examples 4 in which low-temperature maturation was performed. However, Comparative Example 3, in which the pressure of the heating process was high, had a stronger bitterness than the Examples and Comparative Examples with other pressures.

division degree of bitterness Example 1 0 Example 2 -0.43 Comparison Example 1 1.22 Comparison Example 2 0.43 Comparative Example 3 0.74 Comparison Example 4 0.04
