Description

Method for producing beta-glucan-rich sprouted brown rice

[0001] The present invention relates to a method for producing germinated brown rice rich in beta-glucan.

[0002] Numerous research results have proven that a diet involving frequent consumption of processed meat, instant foods, and high-sodium foods can be a major cause of cancer and various adult diseases.

[0003] For example, the American Institute for Cancer Research (AICR) and the Cancer Research Fund (ACRF) state that more than 50% of cancers can be prevented by improving dietary habits to a plant-based diet and obtaining only 10% of necessary calories from animal sources, and they recommend reducing the intake of animal fats worldwide. It is worth noting that this recommendation was based on a three-and-a-half-year compilation and analysis of 4,500 papers by leading cancer researchers worldwide, and it includes recommendations for the consumption of brown rice, whole-wheat bread, vegetables, fruits, and legumes.

[0004] The rationale behind recommending a grain-and-vegetarian diet is to increase the intake of dietary fiber, which is often lacking in a meat-based diet. It is widely known that brown rice is a beneficial food for boosting immunity and maintaining cardiovascular health, as it contains large amounts of inorganic nutrients, including plant fiber, various enzymes, and minerals.

[0005] In particular, sprouted brown rice can compensate for the disadvantages of both brown rice and white rice. For instance, while regular brown rice is richer in nutrients compared to white rice, it has the disadvantage of being relatively difficult to digest and having a rough texture due to the presence of phytic acid. White rice, on the other hand, suffers from the loss of most of the nutrients contained in the embryo during the milling process. However, as the phytic acid in sprouted brown rice transforms into phosphorus and inositol during germination, sprouted brown rice is relatively easier to digest than regular brown rice; furthermore, unlike white rice, it does not undergo a milling process, allowing it to retain the nutrients contained in the embryo intact.

[0006] Despite the advantages of sprouted brown rice, modern dietary habits make it difficult to obtain sufficient nutrients solely through this source. Consequently, there is a continuous demand for fortified sprouted brown rice, which enhances the various nutrients found in sprouted rice and incorporates additional beneficial components. In particular, as modern individuals experience discomfort due to various diseases and ailments caused by weakened immunity resulting from diverse factors, the demand for fortified sprouted brown rice containing ingredients capable of resolving these issues is increasing day by day.

[0007] Accordingly, the inventor of the present invention has completed the present invention after conducting long-term research and development through trial and error to solve the aforementioned problems.

[0008] The present invention aims to provide a method for producing sprouted brown rice that has a soft texture and can be consumed without aversion in order to solve the problems described above, and further to produce sprouted brown rice containing a substantial amount of beta-glucan, which has health benefits such as strengthening immunity, reducing bad cholesterol, and enhancing intestinal function, in order to further improve the health of consumers consuming the sprouted brown rice.

[0009] The technical problems to be solved by the present invention are not limited to the above technical problems, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0010] One aspect of the present invention for solving the aforementioned problem comprises: (a) introducing unsprouted brown rice and water at a temperature set to 45℃ into a germination container;

[0011] (b) Step of adding Phellinus linteus extract to the germination container;

[0012] (c) a first germination step in which brown rice, Phellinus linteus extract, and water are stirred for 2 to 4 hours so that the brown rice is immersed and germinated underwater during the stirring process; and

[0013] (d) Includes a secondary germination step in which the primary germinated brown rice is further germinated in the air.

[0014] According to a preferred embodiment of the present invention, (e) a step of drying brown rice that has undergone secondary germination in an environment at a temperature of 48°C or higher to agglutinate a Phellinus linteus mushroom component containing beta-glucan to the brown rice that has undergone secondary germination; and

[0015] The method may further include a step of adding Phellinus linteus extract such that the weight ratio of Phellinus linteus extract to brown rice added to the germination container is 1:2 to 1:4.

[0016] According to a preferred embodiment of the present invention, step (b) is

[0017] The method may include the step of extracting Phellinus linteus components using nanobubble water for 70 to 74 hours to produce a Phellinus linteus extract containing more than a standard amount of beta-glucan.

[0018] According to a preferred embodiment of the present invention, step (d) is

[0019] It may include a step of germinating brown rice that has completed primary germination in an environment satisfying conditions where the temperature is 23~25℃ and the humidity is 60% or higher.

[0020] According to a preferred embodiment of the present invention, the content of beta-glucan per 1g of brown rice that is secondarily germinated in step (d) may be 120mg to 130mg.

[0021] According to a preferred embodiment of the present invention, the brown rice sprouts that have completed primary germination can be grown to a size of 1 mm or less, and the brown rice sprouts that have completed secondary germination can be grown to a size of 5 mm or less depending on the germination time in the air.

[0022] The present invention can produce germinated brown rice that has a soft texture and can be consumed by consumers without aversion, and can produce germinated brown rice containing a substantial amount of beta-glucan extracted from Phellinus linteus.

[0023] Specifically, beta-glucan is a type of naturally occurring polysaccharide found in abundance in some grains, yeast, and mushrooms, and possesses various health benefits, including boosting immunity, inhibiting cancer cells, reducing cholesterol levels, and enhancing intestinal function.

[0024] For example, according to research results published in the 'Comprehensive Reviews in Food Science and Food Safety' in July 2012, it was confirmed that consuming 3g of beta-glucan daily reduces cholesterol levels and lowers the risk of heart disease by approximately 23%. Additionally, a study published in the Journal of the American College of Nutrition confirmed that consuming 6g of barley beta-glucan daily for 6 weeks is effective in lowering cholesterol levels and reducing body weight. Furthermore, according to research results from the National Cancer Research Institute of Japan, it was confirmed that Phellinus linteus exhibits excellent anticancer effects, with a cancer cell growth inhibition rate of approximately 96.7%.

[0025] In addition, the germinated brown rice produced according to the present invention is prepared using a Phellinus linteus extract containing beta-glucan, and contains other ingredients with health benefits in addition to beta-glucan.

[0026] For example, Phellinus linteus extract contains pelinulin, which helps maintain liver function, and hispidin, a bioactive substance with health benefits related to antioxidant, anti-tumor, anti-diabetic, and cardiovascular function maintenance.

[0027] In addition, germinated brown rice produced according to the present invention allows consumers to consume about 12,500 mg of beta-glucan even when eating one bowl (200 g) of rice cooked by mixing it with white rice in a 5:5 ratio. This is more than 20 times the daily intake of beta-glucan (287.1–534.6 mg) required for beta-glucan products as outlined in the Health Functional Food Codex, allowing consumers to fully enjoy the health benefits of beta-glucan.

[0028] In addition, the present invention allows the degree of germination of brown rice to be set according to consumer preferences, thereby further popularizing brown rice food.

[0029] Specifically, since brown rice has different advantages depending on the degree of germination, consumers can increase their satisfaction with germinated brown rice by selecting a degree that suits their constitution or preference.

[0030] Meanwhile, it should be added that even if an effect is not explicitly mentioned here, the effects described in the following specification and the provisional effects expected by the technical features of the present invention are treated as described in the specification of the present invention.

[0041]

[0042] The method for producing germinated brown rice rich in beta-glucan according to the present invention can be carried out by a germinated brown rice production device. The germinated brown rice production device may include a plurality of components for producing germinated brown rice. For example, the germinated brown rice production device may include a primary germination device, a secondary germination device, a drying device, a nanobubble water generating device, a Phellinus linteus extract generating device, and a control unit.

[0043] The primary germination device is a device for performing primary germination of brown rice, and may include a germination container and a brown rice net included in the germination container.

[0044] The secondary germination device is a device for performing secondary germination of brown rice, and may include an environment creation device capable of creating an additional germination environment, wherein a zone is allocated for additionally germinating the primary germinated brown rice in the air.

[0045] A drying device may refer to a device capable of drying secondary germinated brown rice.

[0046] A nanobubble water generating device may refer to a device capable of generating nanobubble water used in the production of Phellinus linteus extract.

[0047] A Phellinus linteus extract generating device may refer to a device that generates Phellinus linteus extract using nanobubble water generated by a nanobubble water generating device.

[0048] The control unit can control the operation of the devices included in the germinated brown rice manufacturing device. For example, the control unit can receive data regarding temperature, humidity, and vibration from the devices included in the germinated brown rice manufacturing device and control each device based on this data. In addition, the control unit can receive customer demand data for germinated brown rice and adjust the germination process of the brown rice according to the results of analyzing the received customer demand data.

[0049] Figure 1 is a flowchart illustrating the process of manufacturing germinated brown rice rich in beta-glucan according to the present invention.

[0050] Referring to FIG. 1, the process for producing germinated brown rice rich in beta-glucan according to the present invention includes a water supply step (S110), a step of adding Phellinus linteus extract (S120), a first germination step (S130), a second germination step (S140), and a bonding step (S150).

[0051] In the water supply step (S110), after introducing unsprouted brown rice into the germination container, water with a temperature set to 45℃ is introduced.

[0052] The process for producing germinated brown rice rich in beta-glucan according to the present invention may further include a washing step performed prior to the water supply step (S110).

[0053] In the washing step, unsprouted brown rice can be washed using water set to a temperature of 45℃.

[0054] Specifically, the washing step can be performed by stirring water at 45°C and unsprouted brown rice for a certain period of time to remove foreign matter from the surface of the brown rice, and the process of stirring for a certain period of time and then draining the water can be performed two or more times to ensure sufficient washing of foreign matter.

[0055] By stirring the brown rice with water at 45°C during the washing step, the unsprouted brown rice can be pre-soaked, thereby allowing the brown rice to germinate smoothly during the first germination step described later.

[0056]

[0057] In the step of adding Phellinus linteus extract (S120), Phellinus linteus extract is added to the supplied germination container.

[0058] Here, the step of adding Phellinus linteus extract (S120) may include a step of generating Phellinus linteus extract.

[0059] In the step of producing Phellinus linteus extract, Phellinus linteus extract can be produced by extracting Phellinus linteus components using nanobubble water for 70 to 74 hours. When component extraction is performed using nanobubble water, the component extraction speed can be improved by 1.5 times compared to using ordinary water, and the amount of extracted components can also be improved by 1.2 times.

[0060] The Phellinus linteus extract produced through component extraction using nanobubble water can contain more than the standard amount of beta-glucan, thereby enabling a sufficient amount of beta-glucan to penetrate into the interior of the germinated brown rice during the germination process.

[0061] In addition, the weight ratio of Phellinus linteus extract and brown rice introduced into the germination container can be set to 1:2 to 1:4, which is measured to have the best penetration efficiency of Phellinus linteus components, thereby further increasing the amount of Phellinus linteus components penetrating the brown rice during the germination process of the brown rice.

[0062] The components of Phellinus linteus found in Phellinus linteus extract may include other ingredients with health benefits in addition to beta-glucan.

[0063] For example, the Phellinus linteus components included in Phellinus linteus extract may include protein, lipids, ash, carbohydrates, dietary fiber, palmitic acid, stearic acid, lignoceric acid, oleic acid, omega-6 fatty acids, isoleucine, leucine, lysine, phenylalanine, threonine, valine, calcium, linoleic acid, arginine, tyrosine, cysteine, alanine, aspartic acid, glutamic acid, glycine, serine, molybdenum, iron, magnesium, phosphorus, potassium, sodium, zinc, copper, manganese, selenium, iodine, beta-carotene, vitamin B1, vitamin B2, vitamin C, biotin, pyridoxine, hispidin, and proteoglycans.

[0064] According to one embodiment of the present invention, a germinated brown rice manufacturing device can generate nanobubble water using a nanobubble water generating device.

[0065] Specifically, the nanobubble water generating device can supply compressed gas to raw water used as a raw material for nanobubble water through a diffuser comprising a porous film having pores formed with a diameter of 10 to 30 nm.

[0066] In addition, the nanobubble water generating device can irradiate raw water with microwaves set to a frequency of 2400 to 2500 MHz.

[0067] The nanobubble water generating device can generate nanobubble water by rotating raw water irradiated with microwaves while receiving compressed gas.

[0068] According to one embodiment of the present invention, the raw water used for generating nanobubble water may be ionized water in which water clusters are broken down into nanoscale sizes by microwaves and ionized, and in which reduction action does not occur for a certain period of time or longer.

[0069] According to one embodiment of the present invention, a Phellinus linteus extract generating device can generate a Phellinus linteus extract using nanobubble water generated by a nanobubble water generating device.

[0070] Specifically, the Phellinus linteus extract generating device can introduce Phellinus linteus into a component extraction tank and rotate and spray nanobubble water using a plurality of nozzles formed with a diameter of less than a certain amount.

[0071] For example, the device for generating Phellinus linteus extract can divide Phellinus linteus into powders of 1 to 3 cm and introduce them into a component extraction tank. A spray tube comprising a plurality of nozzles that spray nanobubble water can be formed adjacent to the upper or lower surface of the component extraction tank and can be formed such that its length corresponds to the inner diameter of the component extraction tank. Additionally, the center of the spray tube can be fixed at the center of the component extraction tank and rotate in a fan-like manner to spray nanobubble water.

[0072] In addition, the Phellinus linteus extract generating device can heat the component extraction tank for 70 to 74 hours while maintaining the same state for the amount of nanobubbles sprayed into the component extraction tank and the amount of nanobubbles evaporated inside the component extraction tank. While heating the component extraction tank to extract Phellinus linteus components, the nanobubbles inside the component extraction tank can be maintained at 100 to 105°C.

[0073] Here, the weight ratio of Phellinus linteus to the nanobubble water introduced into the component extraction tank can be maintained at 9~11%.

[0074] For example, if the weight ratio of Phellinus linteus to the nanobubble water introduced into the component extraction tank is 9 to 11%, the Phellinus linteus extract generating device can increase the internal pressure of the component extraction tank by a certain amount above the reference pressure without spraying the nanobubble water. In addition, if the weight ratio of Phellinus linteus to the nanobubble water introduced into the component extraction tank exceeds 11%, the Phellinus linteus extract generating device can adjust the internal pressure of the component extraction tank to the reference pressure and spray the nanobubble water to adjust the weight ratio of Phellinus linteus to the nanobubble water to 9 to 11%.

[0075] Figure 2 is a test report showing the beta-glucan content of a Phellinus linteus extract produced through the germinated brown rice production method of the present invention.

[0076] Referring to Figure 2, the beta-glucan content of the Phellinus linteus extract produced using nanobubble water may be 3.5 mg / g or more, and the sugar content may be 1.3 Brix or more.

[0077] In addition, the content of beta-glucan per 1g of germinated brown rice produced using the Phellinus linteus extract produced in this manner may be 120mg to 130mg. Since a predetermined sugar content is measured along with beta-glucan in the germinated brown rice produced according to the present invention, it may be easier to induce consumers to consume germinated brown rice.

[0078] In this regard, Figure 4 is a test report showing the beta-glucan content of a Phellinus linteus extract using conventional purified water.

[0079] Referring to Fig. 4, the beta-glucan content of the Phellinus linteus extract produced using ordinary purified water is about 1.03 mg / g, so the beta-glucan content of the Phellinus linteus extract produced using nanobubble water produced according to the present invention can be said to be more than 3 times that of the conventional method.

[0080]

[0081] In the first germination stage (S130), brown rice, Phellinus linteus extract, and water introduced into the germination container are stirred for 2 to 4 hours, so that the brown rice is immersed and germinated in water during the stirring process.

[0082] Brown rice absorbs the components of the Phellinus linteus mushroom contained in the Phellinus linteus extract during the process of germinating brown rice in water, and the absorption rate of the Phellinus linteus components of brown rice can be improved by using water at 45°C during the process of washing and germinating brown rice in water.

[0083] According to one embodiment of the present invention, the primary germination device may stop stirring at regular intervals and raise the brown rice undergoing primary germination to the surface of the water using a brown rice net formed to be movable up and down inside the germination container. The brown rice net may be formed adjacent to the lower surface of the germination container and may be formed in a form connected to a frame that extends up and down from the center of the germination container. The control unit may transmit a control command to the primary germination device to control the brown rice net inside the germination container to rise or fall by the movement of the frame.

[0084] The primary germination device can generate an image of brown rice by photographing the brown rice that has risen above the water surface through a photographing device located at the top of the germination container. To this end, the primary germination device may include a photographing device positioned at the top of the germination container.

[0085] The primary germination device can determine the degree of germination of brown rice undergoing primary germination by analyzing a brown rice image. The primary germination device can infer the shapes of the brown rice included in the brown rice image. For example, if the shapes of 20% of the brown rice included in the brown rice image are identified or inferable, the degree of germination of the entire brown rice can be inferred based on the identified or inferred data.

[0086] The primary germination device can lower the brown rice mesh and restart stirring when it is determined that the primary germination of the brown rice is not complete, and can terminate the primary germination by draining the water inside the germination container when it is determined that the primary germination of the brown rice is complete.

[0087]

[0088] In the second germination stage (S140), the first germinated brown rice is further germinated in the air.

[0089] The secondary germination of primary germinated brown rice can be carried out in an environment satisfying conditions where the temperature is 23–25°C and the humidity is 60% or higher. The beta-glucan content per 1g of brown rice undergoing secondary germination after the primary germination is completed can be 120mg to 130mg.

[0090] In this regard, FIG. 3 is a test report showing the beta-glucan content of germinated brown rice produced through the germinated brown rice production method of the present invention.

[0091] Referring to FIG. 3, it was confirmed that 1 g of germinated brown rice produced through the germinated brown rice production method of the present invention contains 126.74 mg of beta-glucan.

[0092] According to this, even if a consumer consumes one bowl (200g) of rice cooked by mixing sprouted brown rice produced according to the present invention with white rice in a 5:5 ratio, they can consume approximately 12,500mg of abundant beta-glucan. The figure of 12,500mg is more than 20 times the daily intake of beta-glucan (287.1~534.6mg) that is a requirement for beta-glucan products as guided in the Health Functional Food Code, and corresponds to an amount that allows consumers to fully enjoy the health benefits of beta-glucan.

[0093] According to one embodiment of the present invention, the secondary germination device can cause the sprouts of the secondary germinated brown rice to grow within 5 mm by additionally germinating the primary germinated brown rice in the air for 16 to 24 hours.

[0094] For example, the sprouts of brown rice that have completed primary germination can be grown to a size of 1 mm or less, and the sprouts of brown rice that have completed secondary germination can be grown to a size of 5 mm or less depending on the germination time in the air.

[0095] Specifically, germinated brown rice produced according to the method for producing germinated brown rice of the present invention may exhibit different efficacy depending on the degree of germination.

[0096] For example, germinated brown rice with sprouts less than 1mm in size can have its nutrients maximized. Accordingly, germinated brown rice with sprouts less than 1mm in size has the effect of improving the constitution of consumers with low digestive enzyme activity.

[0097] In addition, germinated brown rice with a germination level of 1.5 may have a decrease in overall nutrients, while specific nutrients such as dietary fiber, minerals, protein, and B vitamins may increase. Accordingly, germinated brown rice with a germination level of 1.5 can provide a brown rice diet suitable for people with an obese constitution.

[0098] In addition, germinated brown rice, in a state where the sprout has germinated to the third stage and roots have begun to emerge, retains certain nutrients and minerals, while the endosperm, which is the starch layer, is almost completely depleted and becomes insoluble. In this state, only minerals, vitamins, and dietary fiber remain that are not broken down even by digestive enzymes. Since germinated brown rice in this state has a very high dietary fiber content, it can facilitate dietary fiber intake by utilizing it, such as by adding it to other foods in powder form.

[0099] According to one embodiment of the present invention, a secondary germination device can grow sprouts of brown rice by setting the additional germination degree of primary germinated brown rice.

[0100] Specifically, the secondary germination device can set multiple growth intervals for the sprouts germinating from brown rice. For example, the growth intervals can be set in increments of 0.5 mm up to a range reaching 5 mm, such as 1.1–1.5 mm, 1.6–2.0 mm, 2.1–2.5 mm, and 2.6–3.0 mm.

[0101] The secondary germination device can receive customer demand data for each growth section and, based on the received customer demand data, can position the primary germinated brown rice in different growth zones. Subsequently, the secondary germination device can set the air germination time for each growth zone differently, thereby allowing the sprouts of the primary germinated brown rice located in each growth zone to grow to different lengths.

[0102] For example, if customer demand data shows that the proportion of customer demand for germinated brown rice with a sprout length of 1.1 to 1.5 mm is 30% and the proportion of customer demand for germinated brown rice with a sprout length of 2.1 to 2.5 mm is 70%, then 30% of the first germinated brown rice can be placed in the first growth zone and 70% of the first germinated brown rice can be placed in the second growth zone. Additionally, if there is customer demand for germinated brown rice with a sprout length of 1 mm or less, the second germination step for the first germinated brown rice with a sprout length of 1 mm can be omitted and the stalemate step can be proceeded.

[0103] When proceeding with the underwater germination of brown rice, if the brown rice is germinated until the sprout reaches 3mm or more, there is a problem in that the brown rice may rot or fail to sprout roots. The present invention allows for additional germination while preserving the condition of the germinated brown rice intact through a secondary germination step in which the primary germinated brown rice is additionally germinated in the air.

[0104]

[0105] In the adhesion step (S150), brown rice that has undergone secondary germination is dried for 18 to 22 hours in an environment with a temperature of 48 to 52°C, thereby allowing the secondary germination of brown rice to be adhesion with a Phellinus linteus mushroom component containing beta-glucan.

[0106] For example, through the first germination stage and the second germination stage, the Phellinus linteus components containing beta-glucan can penetrate into the interior of the germinated brown rice, and through the Phellinus linteus component interlocking stage, the Phellinus linteus components that have penetrated into the interior of the germinated brown rice can be completely interlocked.

[0107] In addition, when drying is performed at a relatively low temperature of 48°C, the drying time increases, but the degree of component adhesion can be further improved, and when drying is performed in an environment that is relatively higher than 48°C, the drying time can be shortened, but the degree of component adhesion can be reduced to some extent.

[0108] Sprouted brown rice, dried after undergoing the binding stage of Phellinus linteus components, does not require washing. Furthermore, as the texture becomes soft during the germination process, it can be cooked without soaking in water. Additionally, even if consumers cook the rice by soaking it in water, it has the advantage of preventing the Phellinus linteus components from leaking out of the sprouted brown rice.

[0109]

[0110] It is obvious to those skilled in the art that the present invention may be embodied in other specific forms without departing from the features of the invention. Accordingly, the above detailed description should not be interpreted restrictively in all respects and should be considered exemplary.
