Description

Method for producing onion pulp for paper and capsules

[0001] The present invention relates to a method for manufacturing onion pulp for papermaking and capsules, and more specifically, to a method for manufacturing plant-based onion pulp that is environmentally friendly and guarantees durability using onion and ink powder.

[0002] On Earth, forests play a key role in mitigating climate change by absorbing carbon dioxide from the atmosphere. They also serve as habitats for a diverse range of organisms, forming ecosystems upon which countless species depend. Furthermore, forests protect and maintain soil, influence crop production, and filter and purify water, providing economic livelihoods and cultural value to countless people.

[0003] Logging these forests, which provide such global value, can impair their natural functions, reduce biodiversity, lead to species extinction and ecosystem instability, negatively impact crop production due to soil erosion, increase water pollution, and potentially trigger industrial crises due to social and economic instability. To prevent these risks and crises and protect forests, strengthening forest protection policies and managing them sustainably are crucial.

[0004] Furthermore, as humanity entered a civilized society, the importance and necessity of continuous challenges and research and development toward "new paper" through innovative thinking regarding "paper," one of the products created through logging of forests, are being emphasized. Paper pulp is one of the materials used to make paper and paper-based products, and is generally made by processing wood such as trees.

[0005] These paper pulps can be categorized into chemical pulp, which is produced through chemical processes, and mechanical pulp, which is produced through mechanical processes. Chemical pulp can be used to produce higher-quality paper, while mechanical pulp offers superior strength and durability, making it a more cost-effective option.

[0006] However, because the paper industry has a significant environmental impact, producing paper pulp using more environmentally friendly methods has recently become a major industry issue. Efforts are being made to utilize renewable resources in the paper pulp production process and minimize pollution generated during chemical processing.

[0007] Furthermore, capsule pulp is one of the materials primarily used to make pharmaceutical capsules containing drugs, and can be used to create capsules of various shapes and sizes used in the pharmaceutical industry. This capsule pulp is made from fibers such as wood, which are then processed into sheets for capsule manufacturing. As a crucial material in the pharmaceutical industry, capsule pulp must be chemically stable, environmentally friendly, and able to maintain adequate strength.

[0008] In addition, conventional drug capsules were manufactured using protein-based gelatin ingredients obtained from animal cartilage, skin, bones, etc., but there was a problem that these could cause indigestion in the body depending on the capsule ingestor, and there was a problem that vegetarians could not consume them.

[0009] The present invention was created in consideration of the above problems, and has the advantage of being able to protect forests environmentally and help with climate change and maintaining the ecosystem by making pulp from onions instead of trees and making paper from the pulp.

[0010] In addition, the present invention can greatly improve productivity by making pulp from onions economically, saving processing costs, cultivation time, and production speed, and in terms of social value, it is environmentally friendly in that it protects the Earth's forests and prevents harm to the natural environment and animals, unlike the limitations of animal capsules made mainly by extracting from animal skins, and it is safer because it is quickly decomposed in the human digestive system, and it can improve the quality of life, especially for vegans and vegetarians, and lay the foundation for human life to move in a better direction.

[0011] In addition, the present invention can serve as a basic technology that plays an important role in providing jobs and food production in the agricultural sector.

[0012] Specifically, the present invention can provide a method for manufacturing onion pulp for paper and capsules, which is more environmentally friendly and ensures durability of the pulp, by manufacturing onion pulp by mixing onion powder and onion pulverization.

[0013] In addition, a method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention can provide a method for manufacturing onion pulp for paper and capsules in which cohesive strength and tensile strength can be secured by designing the ratio of the ink powder to an optimal value through experiments.

[0014] In addition, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention can provide a method for manufacturing onion pulp for paper and capsules with improved performance such that the dried onion sheet can be easily separated from the mold while removing the unpleasant smell of the onion through a step of removing sugar and sulfur of the onion.

[0015] In addition, a method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention can provide a method for manufacturing onion pulp for capsules that can provide a useful function to the human body as a capsule itself by utilizing the unique components of onions.

[0016] A method for producing onion pulp according to the present invention for achieving the above object may include the steps of: crushing onions to remove sugar and sulfur components from the onions to produce onion pulverization; mixing and stirring onion powder and purified water at a predetermined ratio; heating a primary mixture in which the onion powder and the purified water are mixed; stirring the primary mixture with the onion pulverization; placing and molding a final mixture including the onion powder, the purified water, and the onion pulverization, which has been stirred, on a mold; and drying the final mixture, which has been molded.

[0017] The above-mentioned ink powder may be composed of at least one of green onion ink powder, acorn ink powder, and agar ink powder.

[0018] In the production of onion pulp for papermaking, the ratio of the ink powder and the purified water may be 1:60, and in the production of onion pulp for capsules, the ratio of the ink powder and the purified water may be 1:70.

[0019] The step of producing the above onion pulverization may include a step of compressing and first pulverizing the onion, a step of secondarily pulverizing the first pulverized onion, and a step of washing the pulverized onion with purified water.

[0020] The step of drying the final mixture after the above molding is completed may include a step of drying the final mixture at a temperature of 65 degrees Celsius for 1 hour and 30 minutes or more and 2 hours and 30 minutes or less.

[0021] The method for manufacturing onion pulp for paper and capsules according to the present invention has the advantage of being more environmentally friendly and ensuring the durability of the pulp by manufacturing onion pulp by mixing onion powder and onion pulverization.

[0022] In addition, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention has the advantage of ensuring cohesiveness and tensile strength by designing the ratio of the ink powder to an optimal value through experiments.

[0023] In addition, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention has the advantage of improving performance so that the dried onion sheet can be easily separated from the mold or Teflon film by removing a certain amount of sugar components while removing unpleasant odor and toxicity caused by the sulfur components of the onion through the step of removing sugar and sulfur of the onion.

[0024] In addition, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention has the advantage of being able to provide useful functions to the human body as a capsule itself by utilizing the unique components of onions such as quercetin, vitamin C, and potassium.

[0031] Hereinafter, embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0032] FIG. 1 is a flow chart illustrating a method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention. FIG. 2 is a diagram illustrating a method for removing sugars and sulfur from onions in a method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention. FIG. 3 is a diagram illustrating another method for removing sugars and sulfur from onions in a method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention.

[0033] Referring to FIG. 1, a method for manufacturing onion pulp for papermaking and capsules according to one embodiment of the present invention can be manufactured through multiple steps using onion powder and onion pulverization.

[0034] The method for manufacturing onion pulp for paper and capsules described in FIG. 1 only describes common parts in manufacturing onion pulp for paper and onion pulp for capsules according to one embodiment of the present invention, and the method for manufacturing onion pulp for paper and the method for manufacturing onion pulp for capsules according to the present invention differ in factors such as the ratio of the ink powder, the size of the onion particles subjected to compression pulverization, and the final thickness of the onion pulp.

[0035] In addition, the term 'onion pulp' used in the present invention means a rolled form of an onion 'sheet' that has been formed and dried, and the method for forming the onion sheet will be described in detail below.

[0036] Hereinafter, a method for manufacturing onion pulp for papermaking according to one embodiment of the present invention will be described.

[0037] Specifically, a method for manufacturing onion pulp for papermaking according to one embodiment of the present invention may include a step (S110) of removing sugars and sulfur from onions. More specifically, the step (S110) of removing sugars and sulfur from onions may be performed by a method of removing sugars and sulfur from onions using a drip phenomenon and osmotic pressure principle, as illustrated in FIG. 2, or by a method of removing sugars and sulfur from onions by physically destroying the tissue of onions using a compression crusher, as illustrated in FIG. 3.

[0038] For example, as illustrated in Fig. 2, the step (S110) of removing sugar and sulfur from an onion according to the method of removing sugar and sulfur from an onion using the drip phenomenon and osmotic pressure principle of the present invention may include the step (S111) of cutting the onion. The drip phenomenon is a phenomenon in which moisture and various components leak out from a specific object during the process of freezing and then thawing the object.

[0039] Specifically, the step of cutting the onion (S111) may include a step of cutting the onion into a square shape. In this case, the width of the cut onion particles may be formed to be 0.1 mm or more and 1.5 mm or less.

[0040] Thereafter, the step (S110) of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions using the drip phenomenon and osmotic pressure principle may include a step (S112) of freezing onions.

[0041] More specifically, the step of freezing the onions (S112) may include adding purified water to the cut onions and slowly freezing them at a temperature of -18 degrees Celsius or lower for two days or more. Slow freezing and thawing may result in greater destruction of the onion tissue, softening the texture of the onions upon drying, and rapid and increased removal of sugars and sulfur components.

[0042] However, the embodiment of the present invention is not limited thereto, and the step of freezing the onion (S112) may be implemented as a step of slowly freezing the cut onion for two days or more at a temperature of -18 degrees Celsius or lower without adding purified water to the cut onion.

[0043] Additionally, in the step (S112) of freezing the onion according to one embodiment of the present invention, the freezing time of the onion may vary depending on the desired amount of sugar and sulfur removed.

[0044] For example, step S112 of freezing onions according to one embodiment of the present invention can minimize cell wall damage by rapidly freezing the onions to form small, dense ice crystals. Furthermore, rapid freezing results in less moisture loss during thawing, thereby reducing the amount of sugar and sulfur removed from the onions compared to non-rapid freezing.

[0045] Additionally, the step (S112) of freezing onions according to one embodiment of the present invention may result in increased cell wall damage due to the slow freezing of the onions, which leads to the formation of large, low-density ice crystals. Consequently, slow freezing results in greater moisture loss during thawing, and thus the amount of sugar and sulfur removed from the onions may be greater than with rapid freezing.

[0046] Thereafter, the step (S110) of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions using the drip phenomenon and osmotic pressure principle may include a step (S113) of thawing frozen onions.

[0047] Thereafter, the step (S110) of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions using the drip phenomenon and osmotic pressure principle may include the step (S114) of compressing and crushing the thawed onions.

[0048] The step of compressing and crushing the thawed onion (S114) may include a step of crushing the onion to a predetermined size. The particle size of the crushed onion used in the onion pulp for papermaking according to one embodiment of the present invention may be formed to have a width of 0.8 mm or more and 1.5 mm or less.

[0049] As will be described later, the particle size of the onion pulverization used in the onion pulp for capsules according to one embodiment of the present invention may be formed to have a width of 0.1 mm or more and 0.8 mm or less, which is different from the particle size of the onion pulverization used in the onion pulp for papermaking according to one embodiment of the present invention.

[0050] Therefore, the method for manufacturing onion pulp according to the present invention can form the particle size of the onion pulverized product differently depending on the use of the onion pulp, thereby forming the tensile strength of the onion pulp differently depending on the use.

[0051] In addition, the step of compressing and crushing the thawed onion (S114) may include a step of adding salt to induce rapid discharge of moisture and sugar and sulfur components by osmosis. More specifically, the step of compressing and crushing the thawed onion (S114) of the present invention can induce discharge of sugar and sulfur within the onion by adding salt to the crushed onion, utilizing the principle of osmosis. Therefore, the step of removing sugar and sulfur (S110) according to the present invention can remove sugar and sulfur from the onion by thawing the frozen onion and crushing it.

[0052] In addition, as illustrated in FIG. 3, the step (S110) of physically destroying the tissue of the onion and removing sugar and sulfur from the onion through a compression crusher according to the present invention may include a step (S115) of compressing and first crushing the onion.

[0053] More specifically, the step of compressing and first crushing the onion (S115) may include a step of removing the skin of the onion and crushing the raw, unfrozen onion using a wet compression crusher. In this case, the width of the first crushed onion particles may be formed to a length of 1.4 mm or more and 1.6 mm or less. More preferably, the width of the first crushed onion particles may be formed to be 1.5 mm.

[0054] Thereafter, the step (S110) of physically destroying the tissue of the onion using a compression crusher according to the present invention to remove sugars and sulfur from the onion may include a step (S116) of secondary crushing the onion. In this case, the size of the secondary crushed onion particles may be formed to have a width of 0.8 mm or more and 1.2 mm or less.

[0055] As will be described later, the particle size of the secondary onion pulverization used in the onion pulp for capsules according to one embodiment of the present invention may be formed to have a width of 0.1 mm or more and 0.8 mm or less, which is different from the particle size of the onion pulverization used in the onion pulp for papermaking according to one embodiment of the present invention.

[0056] Therefore, the method for manufacturing onion pulp according to the present invention can form the particle size of the onion pulverized product differently depending on the use of the onion pulp, thereby forming the tensile strength of the onion pulp differently depending on the use.

[0057] Thereafter, the step (S110) of physically destroying the tissue of the onion using a compression crusher according to the present invention to remove sugar and sulfur from the onion may include the step (S117) of washing the crushed onion with purified water. The step (S117) of washing the crushed onion with purified water may include the step of washing the crushed onion with salt water.

[0058] More specifically, the step (S110) of physically destroying the tissue of the onion through a compression crusher according to the present invention to remove sugar and sulfur from the onion can be washed away along with the moisture from the onion during crushing through the step (S117) of washing the crushed onion with purified water, thereby removing sugar and sulfur from the onion.

[0059] In addition, the step (S110) of physically destroying the tissue of the onion through a compression crusher according to the present invention to remove sugar and sulfur from the onion can form the particle size of the onion crushed product differently depending on the ratio of sugar and sulfur to be removed.

[0060] Therefore, as described above, the method for manufacturing onion pulp for papermaking according to the present invention can easily separate the onion sheet, which has been dried in a mold or Teflon film, from the mold by removing the sugar component of the onion in various ways.

[0061] If the onion sheet is dried in a mold without removing the sugar component from the onion, there is a problem in that the onion sheet sticks to the mold when separated from the mold or Teflon film due to the sugar component, and the quality of the onion sheet is not secured.

[0062] Accordingly, the present invention has a technical effect of enabling onion sheets to be easily separated from a mold through various methods of removing sugar components from onions, and also improving the quality of onion pulp formed by winding the onion sheets.

[0063] In addition, the present invention has a technical effect of preventing the characteristic onion smell from being emitted from onion pulp for papermaking by removing sulfur components from onions.

[0064] Thereafter, a method for manufacturing onion pulp for papermaking according to one embodiment of the present invention may include a step (S120) of mixing and stirring the onion powder and water at a predetermined ratio.

[0065] More specifically, the step (S120) of mixing and stirring the ink powder and purified water at a set ratio may include a step of mixing the ink powder and purified water at a ratio of 1:50 to 1:62.

[0066] If the amount of the green onion powder is greater than the above-mentioned amount, the green onion powder and the onion powder may harden during drying, thereby weakening the tensile strength of the onion pulp for papermaking.

[0067] Accordingly, the present invention may include a step of mixing and stirring the green tea powder and purified water at a ratio of 1:60 to achieve the most appropriate tensile strength for papermaking. The green tea powder may have the property of coagulating when mixed with water. This green tea powder may include a protein component extracted from seaweed such as kelp or seaweed.

[0068] Additionally, these green tea powders can exist in a powdered form of fine particles with polysaccharide carbohydrates such as amylose or amylopectin or proteins as the main component.

[0069] Therefore, when the green tea starch powder is mixed with water such as purified water, the green tea starch powder can be absorbed into the water and evenly dispersed. At this time, the protein component of the mung bean starch or acorn starch interacts with the water, causing the green tea starch powder aqueous solution to gel.

[0070] Therefore, the aqueous solution of the green tea powder can be transformed into a branched polymer that forms links between chains through gelation, and as the linkage continues, it can be transformed into a larger branched polymer and formed into a single polymer.

[0071] In addition, the jelly powder according to the present invention is not limited to the green bean jelly powder containing mung bean starch, and may be implemented as acorn jelly powder containing acorn starch. In addition, the jelly powder according to the present invention may be implemented as agar jelly powder. In this case, the ratio of the acorn jelly powder may also be configured to be the same as the ratio of the green bean jelly powder.

[0072] Thereafter, a method for manufacturing onion pulp for papermaking according to one embodiment of the present invention may include a step (S130) of heating a primary mixture of onion powder and purified water.

[0073] More specifically, the step (S130) of heating the primary mixture of the ink powder and purified water may include a step of heating the primary mixture until it reaches 100 degrees Celsius, heating it for 5 seconds more after it reaches 100 degrees, and then stopping the heating.

[0074] Specifically, if the time for heating the onion powder is too long, the starch molecules in the onion powder, which is composed of onion powder or acorn powder, are decomposed, which weakens the bond between the onion powder and the starch in the onion powder, resulting in a problem in that the cohesiveness, elasticity, and tensile strength of the final product, onion pulp, are weakened.

[0075] Therefore, the present invention has a technical effect of ensuring cohesiveness, elasticity, and tensile strength of onion pulp by controlling the heating time of the primary mixture of onion powder and purified water within a certain range.

[0076] Thereafter, a method for manufacturing onion pulp for papermaking according to one embodiment of the present invention may include a step (S140) of mixing a primary mixture of onion powder and purified water with onion pulverized material from which sugar and sulfur have been completely removed.

[0077] More specifically, the step (S140) of stirring the first mixture of the onion powder and purified water with the onion powder from which the sugar and sulfur have been completely removed may include a step of stirring in a container so that the sugar component remaining in the onion powder and the starch component of the onion powder can be combined. At this time, the onion powder may be added and stirred in an amount of 80% of the weight of the purified water initially added.

[0078] In addition, in this case, the onion powder can be mixed with the primary mixture containing the starch powder and purified water while the sugar and sulfur components are removed to a certain level through the step of removing sugar and sulfur (S110) and the moisture content is 120%.

[0079] Thereafter, a method for manufacturing onion pulp for papermaking according to one embodiment of the present invention may include a step (S150) of placing the final mixture, after stirring, on a mold and molding it. More specifically, the final mixture may be defined as including the onion powder, the starch powder, and purified water, after stirring.

[0080] Specifically, the step (S150) of placing the final mixture on a mold and forming it may include a step of forming the onion sheet to a thickness of 0.4 mm or more and 0.8 mm or less in the case of the onion pulp for papermaking according to the present invention.

[0081] Thereafter, the method for manufacturing onion pulp for papermaking according to one embodiment of the present invention may include a step (S160) of drying the formed onion sheet.

[0082] More specifically, the step (S160) of drying the formed onion sheet may include a step of drying the onion sheet at a temperature of 65 degrees Celsius for 1 hour and 30 minutes or more and 2 hours and 30 minutes or less. More preferably, the drying time of the onion sheet may be formed to be 2 hours.

[0083] Therefore, the method for manufacturing onion pulp for papermaking according to the present invention can form the cohesiveness, elasticity and tensile strength of the final onion sheet to a level suitable for papermaking by appropriately controlling the drying temperature and drying time of the onion sheet.

[0084] Hereinafter, a method for manufacturing onion pulp for capsules according to one embodiment of the present invention will be described.

[0085] Specifically, a method for manufacturing onion pulp for capsules according to one embodiment of the present invention may include a step (S110) of removing sugar and sulfur from onions.

[0086] More specifically, the step (S110) of removing sugar and sulfur from onions can be performed by using the drip phenomenon and osmotic pressure principle as shown in FIG. 2 to remove sugar and sulfur from onions, or by physically destroying the tissue of onions using a compression crusher as shown in FIG. 3 to remove sugar and sulfur from onions.

[0087] For example, as illustrated in FIG. 2, the step (S110) of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions using the drip phenomenon and osmotic pressure principle of the present invention may include a step (S111) of cutting onions.

[0088] Drip phenomenon is a phenomenon in which moisture and various components leak out from a specific object during the process of freezing and then thawing it.

[0089] Specifically, the step of cutting the onion (S111) may include a step of cutting the onion into a square shape. In this case, the width of the cut onion particles may be formed to be 0.1 mm or more and 1.5 mm or less.

[0090] Thereafter, the step (S110) of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions using the drip phenomenon and osmotic pressure principle may include a step (S112) of freezing onions.

[0091] More specifically, the step of freezing the onion (S112) may include a step of adding purified water to the cut onion and slowly freezing it at a temperature of -18 degrees Celsius or lower for two days or more.

[0092] However, the embodiment of the present invention is not limited thereto, and the step of freezing the onion (S112) may be implemented as a step of slowly freezing the cut onion for two days or more at a temperature of -18 degrees Celsius or lower without adding purified water to the cut onion.

[0093] Additionally, in the step (S112) of freezing the onion according to one embodiment of the present invention, the freezing time of the onion may vary depending on the desired amount of sugar and sulfur removed.

[0094] For example, step S112 of freezing onions according to one embodiment of the present invention can minimize cell wall damage by rapidly freezing the onions to form small, dense ice crystals. Furthermore, rapid freezing results in less moisture loss during thawing, thereby reducing the amount of sugar and sulfur removed from the onions compared to non-rapid freezing.

[0095] Additionally, the step (S112) of freezing onions according to one embodiment of the present invention may result in increased cell wall damage due to the slow freezing of the onions, which leads to the formation of large, low-density ice crystals. Consequently, slow freezing results in greater moisture loss during thawing, and thus the amount of sugar and sulfur removed from the onions may be greater than with rapid freezing.

[0096] Thereafter, the step (S110) of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions using the drip phenomenon and osmotic pressure principle may include a step (S113) of thawing frozen onions.

[0097] Thereafter, the step (S110) of removing sugar and sulfur from onions according to the method of removing sugar and sulfur from onions using the drip phenomenon and osmotic pressure principle may include the step (S114) of compressing and crushing the thawed onions.

[0098] The step of compressing and crushing the thawed onion (S114) may include a step of crushing the onion to a predetermined size. The particle size of the crushed onion used in the onion pulp for capsules according to one embodiment of the present invention may be formed to have a width of 0.1 mm or more and 0.8 mm or less.

[0099] As described above, the particle size of the onion pulverization used in the onion pulp for capsules according to one embodiment of the present invention can be formed to have a smaller size than the particle size of the onion pulverization used in the onion pulp for papermaking according to one embodiment of the present invention.

[0100] Therefore, the method for manufacturing onion pulp according to the present invention can form the particle size of the onion pulverized product differently depending on the use of the onion pulp, thereby forming the tensile strength of the onion pulp differently depending on the use.

[0101] In addition, the step of compressing and crushing the thawed onion (S114) may include a step of adding salt to induce moisture outflow through osmosis. More specifically, the step of compressing and crushing the thawed onion (S114) of the present invention may include adding salt to the crushed onion to induce the outflow of sugar and sulfur within the onion through the osmosis principle.

[0102] Therefore, the step (S110) of removing sugar and sulfur according to the present invention can remove sugar and sulfur from the onion by defrosting the frozen onion and crushing it.

[0103] In addition, as illustrated in FIG. 3, the step (S110) of physically destroying the tissue of the onion and removing sugar and sulfur from the onion through a compression crusher according to the present invention may include a step (S115) of compressing and first crushing the onion.

[0104] More specifically, the step of compressing and first crushing the onion (S115) may include a step of removing the skin of the onion and crushing the raw, unfrozen onion using a wet compression crusher. In this case, the width of the first crushed onion particles may be formed to a length of 1.4 mm or more and 1.6 mm or less. More preferably, the width of the first crushed onion particles may be formed to be 1.5 mm.

[0105] Thereafter, the step (S110) of physically destroying the tissue of the onion using a compression crusher according to the present invention to remove sugars and sulfur from the onion may include a step (S116) of secondary crushing of the onion. In this case, the size of the secondary crushed onion particles may be formed to have a width of 0.1 mm or more and 0.8 mm or less.

[0106] Therefore, the method for manufacturing onion pulp according to the present invention can form the particle size of the onion pulverized product differently depending on the use of the onion pulp, thereby forming the tensile strength of the onion pulp differently depending on the use.

[0107] Thereafter, the step (S110) of physically destroying the tissue of the onion using a compression crusher according to the present invention to remove sugar and sulfur from the onion may include a step (S117) of washing the crushed onion with purified water.

[0108] More specifically, the step (S110) of physically destroying the tissue of the onion through a compression crusher according to the present invention to remove sugar and sulfur from the onion can be washed away along with the moisture from the onion during crushing through the step (S117) of washing the crushed onion with purified water, thereby removing sugar and sulfur from the onion.

[0109] In addition, the step (S110) of physically destroying the tissue of the onion through a compression crusher according to the present invention to remove sugar and sulfur from the onion can form the particle size of the onion crushed product differently depending on the ratio of sugar and sulfur to be removed.

[0110] Therefore, as described above, the method for manufacturing onion pulp for capsules according to the present invention can easily separate the onion sheet, which has been dried in a mold or Teflon film, from the mold by removing the sugar component of the onion in various ways.

[0111] If the onion sheet is dried in a mold without removing the sugar component from the onion, there is a problem in that the onion sheet sticks to the mold when separated from the mold due to the sugar component, and the quality of the onion sheet is not secured.

[0112] Accordingly, the present invention has a technical effect of enabling onion sheets to be easily separated from a mold through various methods of removing sugar components from onions, and also improving the quality of onion pulp formed by winding the onion sheets.

[0113] In addition, the present invention has a technical effect of preventing the characteristic onion smell from being emitted from onion pulp for capsules by removing sulfur components from onions.

[0114] Specifically, in the case of onion pulp for capsules, as a type of food administered orally to the user, the sulfur removal step is also an important factor in terms of usability.

[0115] Thereafter, the method for manufacturing onion pulp for capsules according to one embodiment of the present invention may include a step (S120) of mixing and stirring the onion powder and water at a predetermined ratio.

[0116] More specifically, the step (S120) of mixing and stirring the ink powder and purified water at a set ratio may include a step of mixing the ink powder and purified water at a ratio of 1:63 to 1:83.

[0117] If the amount of the green onion powder is greater than the above-described ratio, the bond between the green onion powder and the onion powder becomes stronger, which may weaken the tensile strength of the onion pulp for papermaking. Therefore, the present invention may include a step of mixing and stirring the green onion powder and purified water at a ratio of 1:70, unlike the method for producing onion pulp for papermaking, so that the most suitable strength for capsules can be achieved.

[0118] Green tea powder may coagulate when mixed with water. Green tea powder may contain protein extracted from seaweed such as kelp or wakame.

[0119] Additionally, this green tea jelly powder can exist in a powdered form of fine particles, mainly composed of polysaccharide carbohydrates such as amylose or amylopectin, or proteins. Therefore, when green tea jelly powder is mixed with water such as purified water, the green tea jelly powder can be absorbed into the water and evenly dispersed. At this time, the protein components of mung bean starch and acorn starch interact with the water, causing the green tea jelly powder aqueous solution to gel.

[0120] Therefore, the aqueous solution of the green tea powder can be transformed into a branched polymer that forms links between chains through gelation, and as the linkage continues, it can be transformed into a larger branched polymer and formed into a single polymer.

[0121] In addition, the ink powder according to the present invention is not limited to acorn ink powder, but may also be implemented as acorn ink powder. In this case, the ratio of acorn ink powder may also be configured to be the same as that of acorn ink powder.

[0122] Thereafter, a method for manufacturing onion pulp for capsules according to one embodiment of the present invention may include a step (S130) of heating a primary mixture of onion powder and purified water.

[0123] More specifically, the step (S130) of heating the primary mixture of the ink powder and purified water may include a step of heating the primary mixture until it reaches 100 degrees Celsius, heating it for 5 seconds more after it reaches 100 degrees, and then stopping the heating.

[0124] Specifically, if the time for heating the onion powder is too long, the starch molecules in the onion powder, which is composed of onion powder or acorn powder, are decomposed, which weakens the bond between the onion powder and the starch in the onion powder, resulting in a problem in that the cohesiveness, elasticity, and tensile strength of the final product, onion pulp, are weakened.

[0125] Therefore, the present invention has a technical effect of ensuring cohesiveness, elasticity, and tensile strength of onion pulp by controlling the heating time of the primary mixture of onion powder and purified water within a certain range.

[0126] Thereafter, a method for manufacturing onion pulp for capsules according to one embodiment of the present invention may include a step (S140) of stirring a primary mixture of onion powder and purified water with onion pulverized material from which sugar and sulfur have been completely removed.

[0127] More specifically, the step (S140) of stirring the first mixture of the onion powder and purified water with the onion powder from which the sugar and sulfur have been completely removed may include a step of stirring in a container so that the sugar component remaining in the onion powder and the starch component of the onion powder can be combined. At this time, the onion powder may be added and stirred in an amount of 80% of the weight of the purified water initially added.

[0128] In addition, in this case, the onion powder can be mixed with the primary mixture containing the starch powder and purified water while the sugar and sulfur components are removed to a certain level through the step of removing sugar and sulfur (S110) and the moisture content is 120%.

[0129] Thereafter, a method for manufacturing onion pulp for capsules according to one embodiment of the present invention may include a step (S150) of placing the final mixture, after stirring, on a mold and molding it. More specifically, the final mixture may be defined as including the onion pulverized product, the onion powder, and purified water, after stirring.

[0130] Specifically, the step (S150) of placing the final mixture on a mold and molding it may include, in the case of the onion pulp for capsules according to the present invention, a step of forming the onion sheet to a thickness of 0.1 mm or more and 0.3 mm or less. Accordingly, the onion pulp for capsules according to the present invention can be molded to a thickness thinner than onion pulp for papermaking, thereby forming a capsule smaller in size than paper.

[0131] Thereafter, the method for manufacturing onion pulp for capsules according to one embodiment of the present invention may include a step (S160) of drying the formed onion sheet.

[0132] More specifically, the step (S160) of drying the formed onion sheet may include a step of drying the onion sheet at a temperature of 65 degrees Celsius for 1 hour and 30 minutes or more and 2 hours and 30 minutes or less. More preferably, the drying time of the onion sheet may be formed to be 2 hours.

[0133] Therefore, the method for manufacturing onion pulp for papermaking according to the present invention can form the cohesiveness, elasticity and tensile strength of the final onion sheet to a level suitable for capsule use by appropriately controlling the drying temperature and drying time of the onion sheet.

[0134] Therefore, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention has the advantage of being more environmentally friendly and ensuring the durability of the pulp by manufacturing onion pulp by mixing onion powder and onion pulverization.

[0135] In addition, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention has the advantage of ensuring cohesiveness and tensile strength by designing the ratio of the ink powder to an optimal value through experiments.

[0136] In addition, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention has the advantage of improving performance so that the dried onion sheet can be easily separated from the mold or Teflon film while removing the unpleasant smell of the onion through the step of removing sugar and sulfur of the onion.

[0137] In addition, the method for manufacturing onion pulp for paper and capsules according to one embodiment of the present invention has the advantage of being able to provide a useful function to the human body as a capsule itself by utilizing the unique components of onions.
