[0020] FIG. 1 is a flowchart showing the schematic flow of a method for preparing a rice husk extract according to one embodiment of the present invention.

[0021] Hereinafter, a method for preparing a rice husk extract and a processed product according to an embodiment of the present invention will be described with reference to FIG. 1.

[0022] First, a step (S101) of washing the rice husk can be performed.

[0023] Considering safety, the above rice husks may primarily be used from eco-friendly rice grown using organic or pesticide-free farming methods.

[0024] The above rice husks can be washed dry or wet to remove foreign substances, such as soil or dust mixed in the rice husks, during the rice harvesting process.

[0025] When washing the above rice husks with water, it is desirable to wash them within the shortest possible time to minimize the loss of water-soluble beneficial components of the rice husks.

[0026] The rice husks washed with the above water can be dehydrated and used immediately, or dried and stored for use as needed.

[0027] Next, a step (S102) of extracting the washed rice husks using water, brine, and ethanol as solvents, respectively, can be performed.

[0028] The water used to extract the washed rice husks mentioned above can be any type of drinking water or purified water.

[0029] The brine used to extract the washed rice husks above may be a brine diluted with solar salt to a salinity of 5% or less, and the salinity can be freely adjusted as needed.

[0030] While any type of ethanol can be used to extract the washed rice husks mentioned above, it is preferable to use natural ethanol, such as fermented alcohol, in consideration of skin irritation and safety.

[0031] The amounts of water, brine, and ethanol used to extract the washed rice husks can be applied by increasing the amount as needed, with a minimum standard of an amount sufficient to fully submerge the rice husks.

[0032] The washed rice husks can be placed in a sealed container, water, brine, or ethanol can be poured in, and the container completely sealed. After leaving it for a certain period, extraction can be performed until the degree of extraction reaches the target value.

[0033] Finally, a step (S103) of preparing a rice husk extract by mixing the water extract, brine extract, and ethanol extract obtained from the washed rice husk can be performed.

[0034] A rice husk extract can be prepared by mixing two or more water extracts, brine extracts, and ethanol extracts obtained from the washed rice husks.

[0035] The ratio of mixing the water extract, brine extract, and ethanol extract obtained from the washed rice husk can be freely adjusted depending on the use of the rice husk extract.

[0036] A rice husk extract can be prepared by mixing the water extract, brine extract, and ethanol extract obtained from the above-mentioned washed rice husk in equal volume or equal weight.

[0037] The rice husk extract prepared above can be commercialized as is and can be used as a raw material for general cosmetics, scrubs, cleansers, disinfectants, and other skin care products.

[0038] In the above example, it can be seen that a rice husk extract effective for improving skin troubles can be prepared by washing the rice husk, extracting the washed rice husk using water, brine, and ethanol as solvents, and then mixing the water extract, brine extract, and ethanol extract of the washed rice husk together to prepare a rice husk extract.

[0039] Rice husk extract can be produced through the process described above.

[0040] FIG. 2 is a flowchart showing the schematic flow of a method for preparing a rice husk extract according to another embodiment of the present invention.

[0043] Considering safety, the above rice seeds may be used preferentially as eco-friendly rice seeds grown using organic or pesticide-free farming methods.

[0044] The above rice seeds can be washed dry or wet to remove foreign substances, such as soil or dust mixed in the rice seeds, during the rice harvesting process.

[0045] When washing the above rice seeds with water, it is desirable to wash them within the shortest possible time to minimize the loss of water-soluble beneficial components of the husk, which is the outer shell of the rice seeds.

[0046] The rice seeds washed with the above water can be dehydrated and used immediately, or dried and stored for use as needed.

[0047] Next, a step (S202) of extracting the washed rice seeds using water, brine, and ethanol as solvents, respectively, can be performed.

[0048] The water used to extract the washed rice seeds above can be any type of drinking water or purified water.

[0050] All types of ethanol can be used to extract the washed rice seeds, but considering skin irritation and safety, it is preferable to use natural ethanol such as fermented alcohol first.

[0051] The amount of water, brine, and ethanol used to extract the washed rice seeds can be applied by increasing the amount as needed, with the minimum standard being an amount sufficient to fully submerge the rice seeds.

[0052] The washed rice seeds can be placed in a sealed container, water, brine, or ethanol can be poured in, and the container completely sealed. After leaving it for a certain period, extraction can be performed until the degree of extraction reaches the target value.

[0053] Finally, a step (S203) of preparing a rice husk extract by mixing the water extract, brine extract, and ethanol extract obtained from the washed rice seeds can be performed.

[0054] A rice husk extract can be prepared by mixing two or more water extracts, brine extracts, and ethanol extracts obtained from the above-mentioned washed rice seeds.

[0055] The ratio of mixing the water extract, brine extract, and ethanol extract obtained from the above-mentioned washed rice seeds can be freely adjusted according to the use of the rice husk extract.

[0056] A rice husk extract can be prepared by mixing the water extract, brine extract, and ethanol extract obtained from the above-mentioned washed rice seeds in equal volume or equal weight.

[0057] The rice husk extract prepared above can be commercialized as is and can be used as a raw material for general cosmetics, scrubs, cleansers, disinfectants, and other skin care products.

[0058] In the above example, after washing the rice seeds, the washed rice seeds are each extracted using water, brine, and ethanol as solvents, and then the water extract, brine extract, and ethanol extract of the washed rice seeds are mixed together to produce a rice husk extract. It can be seen that a rice husk extract effective for improving skin troubles can be produced using the rice seeds that are integral with the rice husk, water, brine, and ethanol.

[0059] Rice husk extract can be produced through the process described above.

[0060] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
