The present invention relates to a method for producing a fragrance composition containing rice bran extract, and more particularly, to a method for producing a diffuser or deodorant by mixing fragrance oil with a mixed solution prepared by immersing polished rice bran in a base solution. It is about.

In general, rice is classified into brown rice or white rice depending on the degree of milling, and rice bran consisting of chaff, rice buds, and rice bran corresponding to the outer husk of rice is obtained as a by-product, except for brown rice or white rice in the milling process. About 30% of the rice bran generated during rice milling is used for the production of rice bran oil, and about 70% is used as feed or fertilizer or disposed of as agricultural waste.

The general composition of rice bran is 12-15% of crude protein, 15-20% of crude fat, 7-11% of crude fiber, 7-10% of crude ash, and 34-52% of carbohydrate when moisture content is 14%. known to contain.

In other words, when the nutritional components of rice are analyzed, 66% of the nutrients are distributed in the rice bran, 29% in the rice bran, and 5% in the rest, so rice bran contains 95% of the nutrients that rice has.

In addition, rice bran contains nutrients such as fat, protein, and dietary fiber, and also contains vitamin A, vitamin B groups such as thiamine, pyridoxine, and niacin, vitamin E, and minerals such as calcium and zinc iron.

In addition, rice bran contains a large amount of lysine, an essential amino acid that is lacking in grains, and more than 70% of the constituent fatty acids are unsaturated fatty acids such as oleic acid, linoleic acid, and linolenic acid, which have excellent nutritional value. In particular, linoleic acid and linolenic acid are omega-3 and omega-3 respectively Polyunsaturated fatty acids (PUFAs) of -6 belong to essential fatty acids that cannot be synthesized in the body and are considered very important nutritionally.

As described above, rice bran is rich in nutrients, but since it is used as feed or fertilizer or treated as waste, a technique for extracting and utilizing active ingredients by fermenting rice bran including rice bran or using it as a cosmetic composition is proposed. It became.

Hereinafter, with reference to the accompanying drawings to be described a preferred embodiment of the method for producing a fragrance composition containing the rice bran extract according to the present invention.

First, in the method for producing a composition for fragrance containing a rice bran extract according to the present invention (1), the milled rice bran is separated into rice bran and rice bran using a mesh net, and sunlight is transmitted to the separated rice bran to a position where sunlight is transmitted. A rice bran drying step (S10) of drying at the desired time, mixing ethanol (athanol), propylene glycol (Propylene Glycol), isopropyl myristate (isopropyl myristate), and purified water (Purified water) A base solution preparation step (S20) of preparing a base solution, and a cold soaking step (S30) of preparing a mixed solution by mixing the dried rice bran and the base solution in a weight ratio of 3:100 and immersing at 15 to 25 ° C. ) and filtering the mixed solution prepared through the cooling step with a 0.05 micron (㎛) nonwoven fabric, mixing the filtered mixed solution with an additive solution, and then aging at 3 to 4 ° C. to prepare a composition for fragrance. Filtering and mixing Step (S40) and a packaging step (S50) of subdivision packaging the fragrance composition that has passed through the filtering and mixing step.

The rice bran drying step (S10) is a step of separating the rice bran from the polished rice bran and then drying the separated rice bran. First, a mesh net is used to separate the rice bran from the polished rice bran.

Here, the mesh network can use a mesh network having 40 to 50 mesh holes, but the size of the mesh holes can be changed depending on the type of rice.

The rice bran separated by the mesh is dried for a certain period of time in the sun, where the sun refers to a space where sunlight passes and wind passes. This space may be an exposed outdoor area, or the separated rice bran may be placed in a box with a ventilation hole through which wind may pass or an open top and sunlight.

In order to minimize the inflow of moisture into the rice bran during this drying process, it is collected and stored at night when sunlight is not transmitted. In addition, when the drying process relies only on sunlight, the drying process may be delayed due to weather in which sunlight is not transmitted for a long time, and a large drying space is required to receive sunlight. Rice bran can also be dried.

In the rice bran drying step (S10), the temperature of sunlight for drying the rice bran is in the range of 25 to 35 ° C., and if the temperature is lower than the temperature range, the drying efficiency of the rice bran being dried is low. Therefore, it is preferable to maintain the above temperature range, and for this purpose, a temperature control means such as a separate hot air fan or a cold air fan may be used.

That is, in the rice bran drying step (S10), the rice bran is separated from the milled rice bran, and then the separated rice bran is dried in a ventilated place at a temperature in the range of 25 to 35 ° C. At this time, the drying time is 6 to 8 days ( days, and preferably dried for 7 days.

In the next base solution preparation step (S20), a base solution is prepared by mixing at least one selected from ethanol, propylene glycol, isopropyl myristate, and purified water It is a step to

The ethanol is a volatile liquid, which serves to volatilize in the air by combining the molecules of the additive solution described below, and propylene glycol is EWG (Environmental Working Group) grade 3, which is a cosmetic stability test, and is an emulsifier in the process of mixing the additive solution with the base solution , It acts as a moisture supplement, and when the additive solution is fragrance oil, it helps to emulsify ethanol and suppresses the volatility of ethanol due to its low volatility, thereby increasing the use period of the fragrance consisting of a mixture of the base solution and the additive solution.

In addition, isopropyl myristate is EWG (Environmental Working Group) grade 1, which is a cosmetic stability test, and serves as an emulsifier and a moisture supplement, helping to emulsify fragrance oil and ethanol, and has low volatility, and the purified water is a solid particle It is water from which all impurities such as microorganisms, organic substances, and dissolved gases are removed and is absorbed into fibers.

In the present invention, the base solution is that the rice bran dried in the rice bran drying step (S10) is immersed and the components of the rice bran are mixed.

For example, when the additive solution to be described below is fragrance oil for forming a fragrance, a base solution is prepared by mixing ethanol and propylene glycol at a weight ratio of 8:2.

Here, when the ethanol and propylene glycol are mixed at a weight ratio of 7:3, there is a problem in that the propylene glycol remains in the fragrance container even after 100 days of use, and when ethanol and propylene glycol are mixed at a weight ratio of 9:1 There is a problem that the fragrance oil to be completely emulsified, which causes layer separation, and as a result, there is a problem in that the emission efficiency of the fragrance is low.

Therefore, the mixing rate of the base solution and the additive solution, that is, the emulsification degree is increased, and the volatility of ethanol constituting the base solution is suppressed to increase the usage period. After a certain period of time, ethanol and propylene glycol It is preferable to mix in a weight ratio of 8:2.

As another example, in the case of preparing a deodorant by mixing an additive solution with the base solution, ethanol, isopropyl myristate, and purified water are prepared in a ratio of 5: 1: 4 A base solution is prepared by mixing in a weight ratio.

At this time, when the ethanol is mixed at 6 or more, isopropyl myristate is mixed at 0 (zero), and purified water is mixed at a weight ratio of 4, the mixing ratio of the addition solution and ethanol is significantly low, and the separation of the addition solution and ethanol proceeds. Due to this, there is a problem in that the concentration of fragrance varies or non-uniform deodorization is performed depending on the storage location of the deodorant stored in the container and the amount to be sprayed.

And when ethanol is mixed in a weight ratio of more than 5 and less than 6, for example, 5.5, isopropyl myristate is mixed in a weight ratio of 0.5, and purified water is mixed in a weight ratio of 4, the mixing ratio of the added solution and ethanol rises to about 80%. The separation of the unmixed additive solution and ethanol proceeds, resulting in a problem that the sprayed fragrance is not uniform and the concentration is different.

On the other hand, when the ethanol is mixed in a weight ratio of 4, isopropyl myristate is mixed in a weight ratio of 2, and purified water is mixed in a weight ratio of 4, the sliding viscosity peculiar to isopropyl myristate is felt, resulting in a low feeling of use. there was.

Therefore, since the layer separation of the additive solution and ethanol does not occur and the concentration of the sprayed deodorant is constant, the deodorization efficiency is high, and the absorption rate is particularly high in the fiber material, so that the efficiency of capturing odor molecules adsorbed on the fiber material is high.

The next cooling step (S30) is a step of preparing a mixed solution by mixing the dried rice bran and the base solution, and the dried rice bran and the base solution are mixed at a weight ratio of 3:100 (ml/g).

In addition, after mixing the rice bran to be immersed in the base solution, it is stored at a predetermined temperature for a certain period of time so that the ingredients contained in the rice bran are mixed with the base solution. immersed for days.

Maintaining the temperature of the base solution mixed with rice bran in the range of 15 to 25 ° C is to provide time for the rice bran mixed in the base solution to mature so that the active ingredients discharged from the aged rice bran are mixed into the base solution.

Here, when the temperature range is less than 15 ℃, there is a problem that the aging of the rice bran does not occur smoothly, and when it exceeds 25 ℃, the aging of the rice bran proceeds excessively, and there is a problem in that unnecessary or severe harmful components are discharged.

At this time, the base solution in which rice bran is not mixed is supplied in the range of 15 to 18 ° C., and the rice bran to be mixed is prevented from being damaged by low temperature in the process of being introduced into the base solution supplied at a temperature of less than 15 ° C.

And in the cooling step (S30), it is preferable to store the base solution mixed with rice bran indoors so that it is not exposed to sunlight. This is because there is a problem in that the degree of ripening of the rice bran mixed with the base solution is different because the position is different.

On the other hand, in the cooling step (S30), in order to maximize the aging efficiency of rice bran, medium or high concentration oxygen is injected. After the first aeration step (S31), a second aeration step (S32) of supplying oxygen (O) at a concentration of 35 to 45% per 10 cm 2 of the area of the maturation vessel includes

The first aeration step (S31) and the second aeration step (S32) are steps of supplying medium or high concentration oxygen to a maturation container containing a fragrance composition, that is, a container containing a base solution mixed with rice bran.

The first aeration step (S31) is to supply oxygen at a concentration of 25 to 35% to 10 cm 2 of the maturation container. As is known, the concentration of oxygen in the atmosphere is 20 to 21% in the case of the city center and 19 ~19.5%, mountains have a concentration of 21-22%, and seas have a concentration of 22-22.5%.

The first aeration step (S31) delivers oxygen having a concentration of 25% or more higher than the concentration of oxygen present in the sea to the maturation vessel to shorten the initial maturation time of rice bran, and It can increase the activity of microorganisms.

The first aeration step (S31) delivers oxygen at a concentration of 25 to 35% per 10 cm 2 of the area of the maturation vessel, and detects the oxygen concentration of the maturation vessel and supplies oxygen at the concentration when it is detected to be below a certain concentration. Or it may be configured to supply a certain amount of oxygen at a certain time.

In addition, the first aeration step (S31) is performed for the first 1 to 2 days of the 7 days, which is the total cooling step (S30). Depending on the amount of storage, it can be changed to 1-3 days.

Next, the second aeration step (S32) is to supply oxygen at a concentration of 35 to 45% per 10 cm 2 of the area of the aging container in which the first aerated rice bran and the base solution are stored, thereby increasing the aging efficiency activated through the first aeration. This is the amplification step.

To this end, in the second aeration step (S32), a relatively high concentration of oxygen is supplied compared to the oxygen concentration supplied in the first aeration step to increase the aging efficiency of the rice bran being aged.

This second aeration step (S32) may be performed continuously after the first aeration step is completed or may be performed after a certain period of rest. It is composed of a form that delivers oxygen to the maturation vessel. After the completion of the first aeration step (S31), it is preferable to take a rest period of one day and then proceed with the second aeration step (S32), which is the component of the rice bran matured through the first aeration step (S31). It is given time to mix with the base solution.

Through the first aeration step and the second aeration step as described above, the maturation time of rice bran can be shortened, and high maturation efficiency can be expected even during the shortened maturation time, and stable maturation is achieved through medium and high concentration oxygen supplied. There is an effect that can go on.

Next, the filtering and mixing step (S40) is a step of preparing a composition for fragrance by mixing the additive solution with the mixed solution prepared through the cooling step (S30).

Here, the filtering and mixing step (S40) first separates impurities or rice bran residues contained in the mixed solution prepared through the cooling step (S30), using a non-woven fabric having a pore size of 0.05 microns (㎛) for this purpose. to filter impurities and residues.

An additive solution is mixed with the filtered mixed solution, wherein the added solution is either a fragrance oil for emitting fragrance or a fragrance oil for deodorizing, and the fragrance oil for emitting fragrance is mixed with the filtered mixed solution in a weight ratio of 1:3. , and the fragrance oil for deodorizing is mixed with the filtered mixed medicine at a weight ratio of 3:97.

The additive solution added to the mixed solution is changed according to the type of the mixed solution, and since the mixed materials and mixing ratio of the mixed solution have been described in the base solution preparation step (S20), duplicate descriptions will be omitted.

On the other hand, the additive solution is any one of fragrance oil for emitting fragrance for use as a fragrance and fragrance oil for deodorizing odor for use as a deodorant, and as an example of fragrance oil for emitting fragrance, fragrance oil made of artificial fragrance (fragrance oil) ), natural fragrances, essential oils, and vegetable oils extracted from plants, or any combination thereof.

In addition, as an example of fragrance oil for deodorizing, it may be made of any one or a combination of artificially produced artificial oil, natural fragrance essential oil, and vegetable oil extracted from plants, trees, or fruits.

A solution obtained by mixing the additive solution with the mixed solution is stored at 2 to 5 ° C for 13 to 15 days (days) so that the mixed solution and the additive solution are aged simultaneously with mixing, preferably at a temperature of 3 to 4 ° C for 14 days. It is stored for days to mature.

The aging temperature and aging period provide a period in which the mixed solution and the additive solution are smoothly mixed and aged after being mixed.

Here, when the aging temperature is less than 3 ° C., there is a problem in that the mixing efficiency of the mixed solution or the additive solution is lowered, and when the aging temperature is higher than 4 ° C., there is a problem in that layer separation occurs between the mixed solution or the additive solution.

The next packaging step (S50) is a step of subdividing and packaging the perfume composition that has passed through the filtration and mixing steps, and after subdividing and storing the perfume composition in a storage container capable of storing a certain amount of the perfume composition, a stopper or cover, etc. This is a step of combining and packaging through a separate packaging box.

As one embodiment of the present invention made as described above, the results of testing the deodorization efficiency of the fragrance (diffuser) prepared by adding fragrance oil for emitting fragrance are provided through FIGS. 2 to 6.

As can be seen from FIGS. 2 to 6, the fragrance prepared according to an embodiment of the present invention has a high deodorization efficiency, and in particular, a bacteria reduction rate of 99.999%, so that deodorization as well as an antibacterial effect can be expected.

On the other hand, FIGS. 7 and 8 are deodorizing performance tests for fragrances without rice bran. In the case of a diffuser without rice bran, the deodorization rate of acetic acid is 92.4%, but ammonia is 46%, so it shows very low deodorization performance. showed up

9 to 10 are performance test results for the deodorant prepared according to an embodiment of the present invention. In the case of the deodorant containing rice bran, the ammonia deodorization rate exceeds 99.8% and the acetic acid deodorization rate exceeds 99.9%. As a result, it can be confirmed that the deodorization rate is high.

It can be confirmed that the deodorizing and antibacterial effects of the fragrance or deodorant prepared using the fragrance composition prepared according to the embodiment of the present invention provided through FIGS. 2 to 6 and FIGS. 9 and 10 are high, and FIGS. Through the test report provided through FIG. 8, it can be seen that the deodorizing and antibacterial effects of the fragrance without rice bran are very low.
