The present invention relates to a perfume product based on dextrins and a method for manufacturing the same, and more particularly, to a perfume product and a method for producing the same long-lasting power by using a dextrin plasma treatment as a carrier.

Plasma refers to a neutral gaseous substance in which high-energy electrons collide with gas molecules or atoms to generate a large number of electrons, cations and heavy atoms or atoms, and the negative and positive charges are the same. Thus, the plasma is characterized by a quasi-neutral gas state composed of neutral particles and charged particles, with cations and electrons collectively behaving. In the plasma, gas molecules, ions, electrons, excited atoms or gas molecules, radicals, discharge light, ultraviolet rays, and the like, are used in various fields by using their functions.

Plasma is in a quasi-neutral gas state, but there are about 10 ⁹ to 10 ¹² ions and electrons per 10 cm 3, which is conductive by an external electric field. In addition, many reactive active species, such as electrons, ions, excited atoms or gas molecules, radicals, etc., exist in the plasma to activate chemical reactions with other materials.

Plasma is divided into thermal plasma and non-thermal plasma. Thermal plasma is a non-thermal plasma in which the temperature of all chemical species such as gas molecules, ions, electrons, excited atoms or gas molecules, and radicals in the plasma is equilibrated. The electrons have high energy while the ions have a temperature almost equal to that of the gas molecules because of their relatively high mass, which makes it easy to generate activated species at relatively low temperatures.

Thermal plasma is an electron, ion, heavy atom or atoms generated by an electric arc discharge or plasma jet at atmospheric pressure to maintain a local thermodynamic equilibrium at the same temperature to form a high-speed flame-like jet. Thermal plasma has an electron density of 10 ¹⁶ to 10 ¹⁹ / cm 3 or more, and can generate plasma at low voltage and high pressure as compared to low temperature plasma. In addition, they emit characteristic spectral or continuous radiation through excited molecules, atoms, recombination, braking radiation, etc., and emit very bright light and ultraviolet rays. Thermal plasma can be used to melt or vaporize a material and can be used as a chemical reaction device that promotes chemical reactions by ions or radicals generated in plasma.

In contrast, the plasma used in the atmosphere is a low-temperature plasma, which is usually below thousands of degrees or close to room temperature, commonly referred to as a low temperature / atmospheric plasma, and is composed of molecules or atoms that are ionized by applying an electric field from outside to induce gas discharge. Depending on the frequency used, it is divided into a medium frequency (MF) plasma using a low frequency alternating current of several kHz to 60 kHz, a radio frequency (RF) plasma using 13.56 MHz, and a microwave plasma of 2.45 GHz. Among them, MF or RF plasma is called DBD (dielectric barrier discharge) plasma, and there is a great possibility of industrial application.

The glow discharge and arc discharge methods are mainly used for DBD plasma production. Glow discharge applies a voltage of about several hundred volts to both ends of the electrode, so that secondary electrons generated by cations in the plasma collide with the cathode, and are accelerated into the plasma by an externally applied electric field to ionize the neutral gas. This is a phenomenon in which an electric current flows between both electrodes by causing an avalanche in which the process of ionizing neutral gas is repeated. At this time, when the pressure increases, it changes from the glow discharge to the arc discharge region. Therefore, in order to form a uniform glow discharge at normal pressure, one of the electrodes must be covered with an insulating plate (dielectric barrier), and an AC power supply frequency of 1 to 60 kHz is applied. You must do it.

DBD atmospheric plasma is widely used in etching, etching, and deposition processes in semiconductor manufacturing, and it is coated by using ions or electrons to modify the physical and chemical properties of the surface while maintaining the mechanical properties of solid materials such as metals or polymers. , Diffusion treatment, surface modification, cleaning, carburizing technology. In addition, it is used for the production of nano-micrometer-sized functional fine particles, and widely used for removing NOx and SOx, odor removal, and volatile organic compounds (VOCs) in flue gas.

On the other hand, the fragrance used in the food, cosmetics, fragrance industry, etc. is used by adsorbing, absorbing or coating liquid fragrance, which is a raw material constituting fragrance, into powder, or by putting liquid fragrance into solid microcapsules to reduce fragrance loss and easy to handle. It is processed into shape and used. In this case, the affinity between the fragrance material and the solid acts as the most important factor, and processing or modifying the solid surface to have an affinity with the fragrance may enhance the persistence of the fragrance.

The present invention relates to a method for producing a high quality fragrance and its preparation by applying a plasma having the above function to a solid powder (carrier) to change the surface properties to promote affinity with the fragrance material, Of course, the purpose is to manufacture high value-added flavors with enhanced processability, and to promote the localization of incense dependent on imports, thereby saving the foreign currency spent on the import of perfumes, and to promote economic development and export-related products.
