Manufacturing method of liquid product containing whole bellflower powder {METHOD OF MANUFACTURING LIQUID TYPE PRODUCT COMPRISING POWDER OF WHOLE PLATYCODON}

The present invention relates to a method for producing a liquid product containing whole bellflower powder, and more specifically, to a method for producing a liquid bellflower product that can shorten the processing time while maintaining the content of useful ingredients by using the bellflower having excellent health functionality as a material. is about

Recently, along with the increase in consumers' interest in functional health food, the demand for bellflower products containing functional ingredients useful for health is gradually increasing.

Bellflower, whose scientific name is Platycodon grandiflorum , grows wild in the mountains and fields of Korea, Japan, and China, and is a dicotyledonous perennial herb in the Cervillaceae family. The root of bellflower used for medicinal purposes is called Platycodi Radix and is rich in saponin and inulin, which strengthens the bronchial mucosa and helps respiratory health. It works. In addition, it is rich in unsaturated fatty acids, so it purifies the blood, helps to excrete sodium, stabilizes blood pressure, and lowers blood cholesterol levels, helping blood circulation

Saponins of bellflower include Platycodin A, C, D and polygalacin D. Among them, Platycodin D has central nervous system inhibitory action, blood sugar strengthening action, and anticancer activity in animal experiments. , is known to have anti-inflammatory effects, acute and chronic inflammation, anti-ulcer and gastric juice suppression effects, and anti-obesity effects. The sugar bound to Platycodin D is D-apiose, a pentose sugar, which is known to be closely related to the physiological action of Platycodins.

Existing studies on bellflower are mostly about pharmacological activity, but there are relatively few studies related to processing method and pharmacological activity.

In relation to the processing method of bellflower, after extracting by adding a solvent to the raw material or powder of bellflower, it is concentrated or dried and used a lot in the manufacture of final food. In this case, only the components extracted from the raw material or powder of bellflower are finally consumed. In the present invention, there is an advantage in that all components of bellflower can be ingested without throwing away by manufacturing a liquid product in the form of adding water by crushing the bellflower.

Therefore, the present invention relates to a method for manufacturing a liquid product using whole bellflower having excellent health functional properties, and relates to a method of reducing the production cost by shortening the processing time and maintaining the content of useful ingredients.

Registered Patent KR 10-2040502

An object of the present invention relates to a method for manufacturing a liquid product using all of the raw material of bellflower having excellent health functionality.

Another object of the present invention is to provide a method for processing bellflower which can reduce the processing time to reduce production costs while maintaining the content of useful components.

All of the above and other objects of the present invention can be achieved by the present invention described below.

According to the present invention,

2 is a graph showing the content of Platicodin D in bellflower samples prepared according to an Experimental Example and a Comparative Experimental Example of the present invention.
3 is a graph showing the content of Platicodin D in a mixture solution obtained by adding water to a bellflower sample prepared according to an embodiment of the present invention.
4 is an HPLC histogram in the analysis of Platicodin D content of a bellflower sample prepared according to an embodiment of the present invention.

Hereinafter, the configuration and operation of the present invention will be described in more detail through preferred embodiments of the present invention. However, this is presented as a preferred example of the present invention and cannot be construed as limiting the present invention for any reason.

Content not described herein will be omitted because it can be technically inferred sufficiently by those skilled in the art to which the present invention pertains.

The present invention provides a method for producing a liquid product containing Tongdolaji powder,

i) irradiating the bellflower with microwaves at a temperature of 30 to 60° C. and drying it for 1 to 3 hours;

ii) drying the bellflower in which step i) is completed for 3 to 24 hours with hot air at 50 to 90°C;

iii) grinding the dried bellflower to 50 to 2,000 mesh; and

iv) adding 1 to 10 times the weight of hot water at 50 to 80° C. to the pulverized bellflower and aging while stirring; may be presented.

In the present invention, it is preferable to use raw bellflower as a raw material for the production of bellflower, which is the main component of a liquid product containing whole bellflower powder, rather than dried bellflower. If it is a fresh bellflower, it can include both whole bellflower and three-cut bellflower.

In the present invention, unlike the prior art, food is not prepared using the extract of bellflower, but the raw material of bellflower is dried and pulverized, and water is added to the pulverized material to prepare a liquid product. That is, a part of bellflower such as an extract is not used. It has the advantage of being able to consume all the ingredients of bellflower. Saponin, an effective component of bellflower, is contained in the outer skin, so it is better to consume all the skin.

In the drying process, which is the core of the present invention, the bellflower is first dried with microwave and then dried with hot air. That is, after irradiating the bellflower with microwaves at a temperature of 30 to 60 ° C, drying for 1 to 3 hours, and then drying with hot air at 50 to 90 ° C for 3 to 24 hours, preferably 8 to 12 hours, to evaporate more than 90% of moisture. . The lower the drying temperature, the longer the drying time may be.

Microwave drying is a method of heating and drying an object using electromagnetic waves. Microwave refers to electromagnetic waves from a frequency of 1 GHz (= 1,000 MHz, wavelength of about 30 cm) to several hundreds of GHz, and since its wavelength ranges from several tens of centimeters (cm) to tenths of a centimeter (cm), it is also called centimeter wave. When a non-metal dielectric is irradiated with microwaves, in accordance with the dielectric properties, electromagnetic waves penetrate into the dielectric and give a high-frequency electric field and magnetic field there. The amount of heat generated is proportional to the frequency of the microwave. Since the penetration depth in the dielectric is inversely proportional to the frequency, in the case of a large object, it cannot be sufficiently heated to the inside. In this case, the frequency must be lowered to heat the object to the deepest depth.

In the microwave drying of the present invention, a microwave in a frequency range of 2 to 3 GHz may be used, but is not limited thereto.

In the case of drying an object using hot air, heat is conducted from the surface to the inside and heated, so if the surface temperature is suppressed so as not to change the quality, a considerable amount of time is required for the heat to reach the inside.

However, in microwave drying, the surface and the inside can be heated almost simultaneously due to the characteristic of heating inside the object, so it can be dried in a short time without compromising the quality of agricultural products.

In the present invention, the optimum drying process conditions were established by combining the hot air drying method and the microwave drying method in drying the bellflower.

When dried bellflower using only hot air drying, it took about 36 hours at around 80℃ to remove about 90% of moisture, and when drying using only microwave drying, a similar moisture content was reached, 4 hours at 40℃ It took

On the other hand, when microwave drying (40°C) and hot air drying (80°C) were combined, it took about 2 hours and 8 hours, respectively, to reach similar moisture content.

As described above, when the dried bellflower dried by various methods was pulverized and the content of platicodin D, a functional ingredient, was analyzed, microwave drying, which had the shortest drying time, showed a low content of platicodin (FIG. 2).

When microwave drying and hot air drying were performed for a total of 10 hours, the platinum D content was similar to that when only hot air drying was performed for 36 hours ( FIG. 2 ).

Therefore, the combined process of microwave drying and hot air drying, which can shorten the drying time and minimize the energy used while maintaining the platinum D content, was applied to compare and analyze the platinum D content according to the drying process. Based on this, Platicodin D content in the bellflower powder mixture prepared by adding hot water to the raw bellflower water, dried bellflower dried material (microwave and hot air dried bellflower powder), and the above-mentioned microwave and hot air drying process of crushed bellflower powder was analyzed. As a result, it was found that the content of Platicodin D in the mixed solution prepared by pulverizing bellflower dried by microwave and hot air and adding water was significantly increased (FIG. 3).

In the present invention, the production time can be shortened without significant change in the content of useful ingredients by manufacturing a liquid product in the form of pulverizing bellflower by microwave and hot air drying, and adding water, and all components of bellflower can be ingested without discarding. There are advantages.

The liquid product containing the bellflower powder of the present invention may contain general food additives, and unless otherwise specified, whether it is suitable as a "food additive" is approved by the Ministry of Food and Drug Safety. It is judged according to the standards and standards for the relevant items of processed food. The items described above include, for example, fructose, oligosaccharide, sugar, ketones, vitamins, glycine, potassium citrate, nicotinic acid, chemical compounds such as cinnamic acid, depigmentation, licorice extract, crystalline cellulose, high color pigment, honey, and guar gum. and natural additives, such as sodium L-glutamate preparations, noodle-added alkalis, preservatives, and mixed preparations such as tar dye preparations.
