Ginseng is a perennial semen oily plant belonging to the genus Ochinacea, and its efficacy is widely known in various medical books. Therefore, it has been widely used as a herb medicine in many fields. In recent years, it has been widely used as a health food material have.

Generally, ginseng is a very slow-growing crop. It grows from the outcrops once a year, leaves grow, and grows for several generations. It takes 3-4 years for seeds from sowing to production , Medicinal herbs are 5 ~ 6 years long, and during cultivation, the harvest is less than the first cultivation due to various insect pests, natural disasters and other reasons, which is very disadvantageous for capital recovery and management.

However, these ginsengs have been shown to be effective in the promotion of brain activity, treatment and prevention of adult diseases (treatment and prevention of diabetes and cancer, blood pressure control, atherosclerosis and hyperlipidemia treatment), body resistance enhancement function (radioactive defense function, Toxicity prevention, heavy metal detoxification ability).

The ginseng having the above effect is cultivated for a long time in the same soil, and the fixed sunshine greenhouse for cultivation is opened, and the damage caused by the pest is much widespread. In order to prevent it, chemical pesticide is often used.

Thus, although ginseng takes a long time from sowing to production, there is a problem that only the root is harvested without using the leaf of ginseng at harvest due to the use of the chemical pesticide.

However, if the ginseng is effective not only in its root but also in its leaves, and if it can be shipped to the product without discarding the leaves of ginseng, the producer can improve the economical efficiency in terms of growth period and effort. You can broaden your choice. Therefore, it is necessary to develop a technology that can process the leaves of ginseng as a product without throwing away leaves.

As shown in FIG. 1, the method for manufacturing a powdered tea using ginseng leaves according to the present invention includes a separation step S10, a cleaning step S20, a semi-drying step S30, a cutting step S40, S50) and a powder forming step (S60).

The separation step (S10) is a step of separating leaves from ginseng. In the separation step (S10), the ginseng cultivated in the culture medium or spraying water is collected to select the target ginseng to be powdered tea, And separating the leaves from the leaves.

In general, the effectiveness of ginseng in hepatitis patients has been proven in ginseng such as promoting protein synthesis in vivo, increasing the regeneration rate of partially resected liver, demonstrating the effect of restoring liver function against acute liver injury, promoting hepatic cholesterol metabolism, It promotes the metabolism and excretion of alcohol and prevents alcohol-induced liver injury.

In addition, ginseng has the effects of hypoglycemia, identification of insulin analogues effective for diabetes, clinical efficacy for diabetes, and improvement of general subjective symptoms. Ginseng's hypoglycemic effect is very effective and excessive diabetes Diabetics can take it safely because there is no risk of knocking down.

In addition, it is known that ginseng has anticancer effects, anti-fatigue action, arteriosclerosis and hypertension, anti-stress action, central nervous system, anemia and immunity enhancement.

Ginseng with such an effect is slightly different in efficacy depending on the site. The outpour is good when the sputum is cold and the chest is tight, the body is good for the lack of energy and fatigue, and the root is effective for coughing or nausea.

In addition to the roots of ginseng, leaves contain anti-diuretic ingredients. Ginseng leaves also contain saponin, which makes skin cells vigorous.

In addition, the ginseng leaf has an excellent anticancer effect, so that it has a cancer prevention effect, an effect of suppressing weight gain due to high fatness, an effect of stimulating the stomach, and a function of breathing smoothly.

According to the cultivation method, the ginseng having the above effect can be divided into a non-cultivation method and a hydroponic cultivation method. Here, the hydroponic cultivation ginseng is cultivated environmentally without using chemical pesticides. Using the hydroponic cultivation method and the clean environment management technology without chemical pesticide in the high-tech greenhouse, the fresh ginseng is produced in a short period (3 ~ 4 months).

The composition and content of saponin in the hydroponically grown ginseng were compared with the ginseng cultivated in the non - cultivated area as follows.

First, the composition and content of saponin in each part of ginseng cultivated in Baejigyeong is shown in Table 1.

Saponin composition

The total saponin content of ginseng rhizome produced by spraying method was 12.3mg / g, and the saponin content of sprayed ginseng leaves was 107.4mg / g, which was 8.7 times more than rhizome.

The saponin contents shown in Table 1 and Table 2 are based on the 2008 annual data of the National Institute of Horticultural Science.

As described above, the ginseng has an effect on the leaves as well as the roots. The ginseng leaves can be separated from the ginseng in the separation step (S10) in order to produce the leaves and safely process them for commercialization.

The cleaning step S20 is a step of cleaning the leaves separated in the separation step S10. In the cleaning step S20, the leaves are ultrasonically cleaned by an ultrasonic cleaner, or the leaves are bubble-washed by a bubble cleaner, It is possible to sterilize the microorganisms while removing foreign substances present in the microorganisms.

Specifically, when the leaves are ultrasonically cleaned by the ultrasonic cleaner in the cleaning step (S20), the leaves of the ginseng may be put into a washing tank, and the cleaning process may be performed by the washing water. At the same time, The impurities adhering to the leaves are removed by flowing washing water, and the heavy metals and residual pesticides which may be present may be separated from the surface of the leaves by ultrasonic waves emitted from the ultrasonic transducer .

When the leaf is bubbled by the bubble cleaner in the cleaning step S20, the leaf of the ginseng is put into a bucket and the bubble cleaner such as an air blower and an ozone generator is operated to wash the leaf by vibration caused by air bubbles in the water So that microorganisms can be sterilized while removing foreign substances present in the leaves.

In addition, in the cleaning step S20, in addition to the ultrasonic cleaning method and the bubble cleaning method described above, it is generally possible to clean the leaf using another cleaning method that can clean the leaf without damaging the leaf of the ginseng Of course.

The semi-drying step S30 is a step of semi-drying the leaf washed in the washing step S20. In the semi-drying step S30, the leaf is semi-dried so that the moisture content of the leaf is 20 to 40% can do.

Generally, drying methods include natural drying at room temperature, hot air drying using hot air, cold air drying using cold air, freeze drying at low temperature, vacuum drying, spray drying, and drying using far infrared rays. S30), the leaves may be semi-dried using one or more of these methods so that the moisture content of the leaves is 20 to 40% by weight.

When the leaf washed in the washing step (S20) is maintained in the raw state, the effective ingredient contained in the leaf may be altered as the leaf swells up. In order to prevent the problem, in the present invention, It is possible to prevent the leaf from swelling by cutting the leaf into a slice in step S40.

If the leaf is sliced in the cutting step S40 without performing any treatment on the leaf after the washing step S20, the liquid material may be generated in the cut leaf and may flow out of the leaf However, when the liquid material is generated in the leaves thus cut out to the outside of the leaves, there may arise a problem that the efficacy components contained in the leaves are remarkably deteriorated.

Therefore, the semi-drying step (S30) may be performed by semi-drying the leaves washed in the washing step (S20) before cutting the sliced leaves in the cutting step (S40) And can be prevented from flowing out to the outside of the leaf.

The cutting step S40 is a step of cutting the semi-dried leaf into a slice shape as described above. In the cutting step S40, when the leaf is swollen, The leaves may be cut into slices to prevent deterioration.

The freeze-drying step (S50) is a step of freeze-drying the cut leaf.

Generally, freeze-drying is a type of drying, which is achieved by sublimation of freezing the material and lowering the partial pressure of the water vapor to make the ice directly steam. (6 mbar or 4.6 Torr). Moisture in the form of ice under low pressure is subdivided into water vapor instead of being converted into liquid by supplying thermal energy. Because the sublimed ice crystals leave space, the dried material contains a large number of gaps and is easily re-hydrated upon re-hydration due to its easy water absorption. This is one of the greatest features of freeze drying.

This intrinsic property of freeze drying is derived from the Greek word "absorbs solvent" and is named "Lyophilization". Important constituents of the material are held fixed during sublimation drying by ice crystals and the shape of the dried material is almost the same as the frozen form of the wet material and the molecular movement to the surface to form a skin is reduced. Drying at low temperatures minimizes damage and fixes volatile constituents.

This freeze-drying method minimizes and inactivates damage to heat-sensitive materials, facilitates the penetration of moisture and is easy to crumble, enables precise and clean filling, and enables rapid and complete re-hydration. .

Today, consumers are in the age of well-being, preferring not only simple flavors but also differentiated flavors, intrinsic colors, nutrients (such as vitamin mineral enzymes), and texture.

The freeze-drying method is advantageous in that it can make any processed food in a state of keeping the taste, nutrition, color, and flavor as it is, as deep as it is natural, as much as possible, so as to satisfy consumers' preference.

In the freeze-drying step (S50), the sliced leaves are placed in a freeze-dryer, and then the temperature is gradually increased from -40 ° C to 30 ° C in order to minimize destruction of nutrients in leaves of ginseng And the specific time is controlled at a specific temperature to simultaneously freeze and dry the ginseng leaves so that the moisture content of the cut leaf is 10% by weight or less, preferably, to prevent the occurrence of various bacteria such as fungi, The leaf may be freeze-dried such that the moisture content is 1 to 5% by weight.

The powder forming step (S60) is a step of pulverizing the lyophilized leaf to form ginseng leaf powder. In the powder forming step (S60), the ginseng leaves having been freeze- It is preferable to grind ginseng leaves at a size of about 50 mesh to form ginseng leaf powder.

FIG. 2 is a second block diagram of a powdered tea making method using ginseng leaves according to the present invention.

As shown in FIG. 2, the method of manufacturing a powdered tea using ginseng leaves according to the present invention may further include a water removing step (S25) between the washing step (S20) and the semi-drying step (S30) have.

The water removing step (S25) is a step of removing the water of the washed leaf. In this water removing step (S25), the water of the ginseng leaves can be removed by the sun and cold air of 5 to 15 占 폚.

FIG. 3 is a third block diagram of a powdered tea making method using ginseng leaves according to the present invention.

As shown in FIG. 3, the powdered tea making method using ginseng leaves according to the present invention may further include a packing step (S70) after the powder forming step (S60).

The packaging step (S70) is a step of packing the crushed ginseng leaf powder. In the packaging step (S70), the crushed ginseng leaf powder is packed in a container made of glass or another material, packed in a disposable plastic bag, The user can produce the powdered tea product using the ginseng leaf by using other means, and the user can take the powdered tea from the powdered tea product produced in the packing step (S70) have.
