Description

Technical Field [0001] The present invention relates to a method for producing sesame oil and perilla oil for reducing benzopyrene,

The present invention relates to a method for producing sesame oil and perilla oil for reducing benzopyran, and more particularly, to a method for producing sesame oil and perilla oil for reducing benzopyran, And to a method for producing sesame oil and perilla oil having a clear and clear golden flavor.

Generally, oils such as sesame oil and perilla oil are roasted after squeezing sesame or perilla and squeezed out, so they have unique flavor. Unsaturated fatty acid (omega 3) reaches 80% ~ 90% The content of linolenic acid is as high as 60%, which prevents the growth of breast and colon cancer, improves learning ability, and is effective in preventing heart disease. Sesame oil and perilla oil also contain natural antioxidants sesamil and three citizens. This is a powerful antioxidant that helps maintain clean blood.

Sesame oil and perilla oil are roasted at high temperature using a roaster machine, then pressed, milked and extracted. In sesame oil and perilla oil produced by this general manufacturing method, benzopyrene, which is a polycyclic aromatic hydrocarbon compound, is generated when sesame is roasted in the distribution step.

More than 200 derivatives of polycyclic aromatic hydrocarbons (PAHs) have been known, and their carcinogenicity has been revealed. Among these, benzopyrene (3,4-benzopyrene) has been found to be particularly carcinogenic. Benzopyrene is a carcinogen that contains not only carbon and hydrogen but also other elements such as nitrogen, sulfur and oxygen. It has low solubility in water and good melting properties in oil, and is produced by combustion or high temperature pyrolysis. In food, it is a substance that can be generated in the process of heating food. It is produced by incomplete combustion of carbohydrate, protein, fat, etc. which are the main components of food during high temperature cooking and processing of food. Especially, , Smoked products, etc. It is known that benzo - pyrene is contained in high - temperature processed foods and high - temperature cooked foods such as crushing and keeping coffee and coffee.

The main cause of benzopyrene generation in the production of sesame oil and perilla oil is in the process of frying.

First, the stirrer is used to stir the sesame in the roasting process. At this time, the physical impact is applied to the sesame by the rotation of the stirrer, and the sesame is broken and many pieces are formed. These fragments are easily burned and thus generate benzopyrene.

The second is that the roasting process takes place at high temperatures. Generally, sesame roasting is carried out at a high temperature of 150 to 200 DEG C, but roasting at a temperature of 120 DEG C or higher necessarily generates benzopyrene.

Accordingly, Korean Patent Publication No. 10-2003-0008236 " Process for producing high purity sesame oil "(prior art 1) has been disclosed in an effort to minimize the content of benzopyran, and Patent Document 10-2016-0042536 &Quot; Method for manufacturing sesame oil "(prior art 2) has been proposed.

In the prior art 1, indirect heating is performed at 30 to 100 캜 by adding sesame to indirect heating. Squeezing and heating the heated sesame oil; A first purification step of transferring the milk oil to a purification tank, precipitating the mixture at 30 to 40 ° C for 7 to 10 days, and then removing precipitated impurities; And a second purification step of adding edible clay to the first purified oil and heating it to 70 to 80 캜 and then filtering the impurities by filtration.

However, the prior art has a problem in that it takes a considerable time to precipitate the milk oil for 7 to 10 days and there is a possibility that the oil may be deteriorated and discolored due to rancidity, And a complicated process of mixing and refining them.

In prior art 2, in producing sesame oil, benzopyrene may inevitably be generated in the roasting step of exposing to a high temperature of 150 ° C to 170 ° C for 7 to 10 minutes. In this case, The problem of the origin of the synthetic material which can not be filtered by the filtration device has been found, and the step of exposing to the steam after the frying step has been followed, resulting in an 80% And a moisture content of ~ 120%. In other words, the moisture content of the produced oil is more than necessary, so the acidity of the production and packaging stage is 7.3 and the normal value is 7.6 ~ 7.0. At 6 months of age, the acidity is 5.7, which is the level of concern about the acidification of blood. This is a phenomenon that occurs when a large number of water molecules, which are likely to be bound to oxygen, are contained in the preservative component. Ranceling is a problem that must be overcome in common in the distribution process. It is known that active oxygen created by autoxidation combined with oxygen in the opened oil affects each function of the human body. Skin diseases such as aging, atopic dermatitis, psoriasis and arteriosclerosis are known to cause cardiovascular diseases.

The present invention has been made in order to overcome the above problems, and it is an object of the present invention to provide a method and apparatus for preventing the fragmentation due to physical collision, which is the main cause of benzopyrene, And to provide a method for producing sesame oil and perilla oil which can minimize the occurrence of benzopyrene by omitting the process.

It is another object of the present invention to provide a method for producing sesame oil and perilla oil having a clear and clear golden color while effectively removing impurities by refining and refining milk after milking.

As described above, the present invention prevents the fragmentation due to physical collision, which is the main cause of benzopyrene, by omitting the process of roasting at a high temperature by applying steam at a low temperature after steam steaming instead of the conventional high-temperature roasting process, Can be minimized.

In addition, since the water content of the oil can be reduced to 10 to 15%, the acidity can be suppressed because the water content of the sesame oil can be drastically lowered by baking the product with water vapor.

Hereinafter, a method for producing sesame oil and perilla oil for benzopyran reduction according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the method for producing sesame oil and perilla oil for reducing benzopyran according to an embodiment of the present invention includes a washing step of washing sesame with water, a steaming step of adding steam to the sesame washed in the washing step, A baking step of baking the steamed sesame oil with a fire and baking at 90 to 100 ° C for 10 to 20 minutes, a milking step of squeezing oil to squeeze the sesame baked in the baking step, and the oil obtained in the milking step, To 10 hours to precipitate impurities, and a purification step of filtering and separating the oil separated from the precipitate generated in the precipitation step. Each step will be examined in detail.

1. Cleaning step

First, in the washing step, the sesame is washed with clean water. The sesame which can be used in the present invention is sesame or perilla.

Through the cleaning process, it is possible to remove various foreign substances and scrap on the surface of sesame. Remove the water by putting it on the cleaned sieve.

2. Stage of capital increase

Unlike the conventional technique in which the sesame is roasted at a high temperature after the washing, the present invention applies a technique in which water vapor is added and then baked at a low temperature. This is to prevent fragments from breaking due to physical impact during sesame frying, effectively preventing the occurrence of benzopyrene from burning fragments.

After performing the washing step, steam is added to the washed sesame to carry out the boiling step.

The boiling step exposes the sesame to water vapor to bloom sesame to facilitate the milking process and prevent the generation of benzopyrene.

In order to add steam, it is necessary to put sesame into the inside of the container, and then to supply the water vapor to the inside of the container. For example, steam can be blown into the container by applying steam of 100 DEG C for 2 to 8 minutes.

3. Baking Step

Next, the steamed sesame is added to the steamed sesame in the steaming step and bake at 90 to 100 DEG C for 1 to 5 minutes.

This baking step is different from the conventional roasting process in which sesame seeds are placed on a hot pan and roasted while stirring. The baking step applied to the present invention differs from the conventional roasting process in that it directly adds fire to the sesame, rather than indirectly applying heat through the fan. Therefore, since there is no need to use a stirrer as in the prior art, no physical collision occurs in the sesame, and the sesame is not broken and fragmented.

Through the baking step, the flavor of sesame can be increased, and at the same time, the moisture content of the steamed sesame can be lowered during the boiling step.

If the oil is squeezed immediately after steamed with sesame oil, the content of water contained in the oil is increased. This is because the moisture content of the sesame oil exposed to water vapor is high at the enhancement stage. The moisture contained in the oil promotes the spoilage of the oil.

Accordingly, the present invention has a baking effect by adding a fire to the steamed sesame after the boiling step, thereby increasing the flavor of the beverage, and at the same time, the moisture content of sesame can be greatly lowered by the drying effect.

In order to bake sesame by putting fire, you can put sesame into the inside of the container, and then supply fire to the inside of the container to burn sesame. Firearms can be generated using gas burners. The flame generated from the gas burner is supplied to the inside of the container by appropriately adjusting the temperature. At this time, when the temperature inside the container to which the firebox is supplied exceeds 120 ° C, the generation of benzo-pyrene rapidly increases, so that the temperature for baking sesame is preferably 90 to 100 ° C. The baking time is suitably 1 to 5 minutes.

The water content of sesame baked by the firebox is preferably 20 to 40% by weight.

4. Milking stage

Next, the sesame which is baked in the baking step is squeezed and oil is squeezed. The oil squeezed from sesame is sesame oil, and the oil squeezed from the perilla is perilla oil.

Milking is carried out using a conventional press.

5. Precipitation step

Next, the oil obtained in the milking step is allowed to stand in the sealed container for 5 to 10 hours to precipitate the impurities, thereby making the oil concentration constant.

Through the precipitation step, the impurities precipitate at the bottom of the vessel to form a precipitate. After the settling, tilt the container and carefully follow only the oil on the deposit.

6. Purification step

Next, a purification step is performed in which the precipitate generated in the precipitation step is separated from the separated oil to remove the suspended matter.

Fine suspended solids that have not been removed in the precipitation step are removed in the purification step.

This purification step can purify the oil using a filter.

An example of the filter is shown in Figs. 4 and 5. Fig.

Referring to FIGS. 4 and 5, the filter may be provided as first and second filter modules 10 and 30 stacked vertically.

The first filter module 10 includes a first bank 11 formed by cutting the first bamboo 11, a first adsorption layer 17 formed on the inner circumferential surface of the first bank 11, And a first molten steel pipe (20) installed vertically in the vertical direction.

The first bank 11 can be obtained by cutting a first bamboo having a certain diameter. For this purpose, the first bamboo is cut at a position spaced upward from the nod 13 and at a position spaced apart from the nod 13 below the nod 13. Thus, the first bank 10 is opened and the lower bank 11 is closed by the nail 13.

The first adsorption layer (17) is formed on the inner peripheral surface of the first bank (11). The first adsorption layer (17) is for removing fine suspended matters in the oil flowing into the first bank (11). The first adsorption layer 17 can be formed by attaching small particles or large pieces of activated carbon to the inner peripheral surface of the first bank 11. In addition, the first adsorption layer 17 can be formed by carbonizing the inner circumferential surface of the first bank 11. For this, the first adsorption layer 17 may be formed by injecting a gas such as gas into the first adsorption column 11 to burn the inner circumference surface of the first adsorption column 11. [ In this case, it is preferable to form the first adsorption layer 17 by burning 1/4 to 1/2 of the thickness of the first bank 11. The first adsorption layer (17) formed by burning bamboo has fine pores and a large surface area, so that the adsorption effect is high. The first adsorbing layer (17) adsorbs and removes fine suspended particles in the oil flowing into the first bank (11).

The first flow pipe (20) is vertically installed inside the first bank (11). The first molten steel pipe (20) has a cylindrical structure in which upper and lower portions are opened. A thin wall made of thin bamboo can be used as the first molten steel pipe (20). In this case, cut between the node and the node, and prepare the barrier that is not blocked inside.

At least one through hole (14) is formed in the node (13) forming the bottom of the first bank (11) for installing the first flow pipe (20). The through hole 14 is formed around the engaging hole 15 to be described later. The lower portion of the first flow pipe (20) is inserted into the through hole (14). The upper end of the first flow pipe 20 is located inside the first bank 11 and the lower end of the first flow pipe 20 protrudes into the interior of the second filter module 30.

When the oil flowing into the first bag 11 reaches a predetermined height, the oil flows into the first flow pipe 20 beyond the upper end of the first flow pipe 20. The oil flowing into the first flow pipe 20 moves downward along the first flow pipe 20 and is discharged into the second filter module 30.

In this way, it is possible to effectively prevent the sediment from being discharged to the second filter module 30 even if the sediment is generated on the bottom of the first bank 11 through the first flow pipe 200. In order to enhance the filtration effect, A porous filter material can be filled in the inside of the flow pipe. Activated carbon and zeolite can be used as a filter medium.

The second filter module 30 includes a second blanket 31 formed by cutting the second bamboo, a second adsorption layer 33 formed on the inner peripheral surface of the second blanket 31, And a second sidewall pipe 40, which is vertically and vertically installed.

The second bank 31 is coupled to the lower portion of the first bank 11. For example, the upper portion of the second bank 31 is inserted into the lower portion of the first bank 11 in the inserted state. To this end, the diameter of the second bank 31 is smaller than that of the first bank 11.

The second bill 31 can be obtained by cutting a second bamboo having a certain diameter. The second bamboo uses a smaller outer diameter than the first bamboo. The second bamboo is cut at a position spaced upward from the node 33 and at a position spaced apart from the node 33 from the node 33 via the node 33 to obtain the second bank 31. The second bank 31 has a structure in which the upper portion is opened and the lower portion is closed by the nail 33.

The second adsorption layer (37) is formed on the inner peripheral surface of the second bank (31). The second adsorption layer 37 is for removing secondarily suspended fine particles in the oil introduced into the second bank 31. The second adsorption layer 37 can be formed by attaching small particles or large pieces of activated carbon to the inner peripheral surface of the second bank 31. In addition, the second adsorption layer 37 can be formed by carbonizing the inner circumferential surface of the second bank 31. For this purpose, the second adsorption layer 37 may be formed by injecting a fire in the second charge 31 to burn the inner circumference of the second charge 31. In this case, it is preferable to form the second adsorption layer 37 by burning 1/4 to 1/2 of the thickness of the second bank 31. The second adsorption layer (37) formed by burning bamboo has fine pores and a large surface area, and thus has a high adsorption effect. The second adsorption layer 37 adsorbs and removes fine suspended particles in the oil flowing into the second bank 31 through the first flow pipe 20.

The second flow pipe (40) is vertically installed inside the second bank (31). The second sidewall pipe 40 has a tubular structure in which upper and lower portions are opened. And the barrel obtained by cutting the thin bamboo into the second molten steel pipe 40 can be used. In this case, cut between the node and the node, and prepare the barrier that is not blocked inside. The second sidewall pipe (40) may be smaller in diameter than the first sidewall pipe (20).

At least one through hole is formed in the node 31 forming the bottom of the second bank 31 for installing the second flow pipe 40. And the lower part of the second flow pipe 40 is inserted into the through hole. The upper end of the second flow pipe (40) is located inside the second bank (31) and the lower end of the second flow pipe (40) is projected outside the second bank (31).

The oil flows into the second flow pipe 40 through the upper end of the second flow pipe 40 when the oil flowing into the second flow pipe 31 reaches a predetermined height. The oil flowing into the second sidewall pipe 40 moves downward along the second sidewall pipe 40 and is discharged to the outside. In order to increase the filtration effect, a porous filter material can be filled in the inside of the second flow pipe. Activated carbon, zeolite and the like can be used as a filter medium.

The first filter module 10 is provided with a dispersing means (not shown) so that oil can be dispersed widely into the second bank 31 when the oil flows into the second bank 31 through the first bank 20, 50).

The insertion bar 51 inserted into the coupling hole 15 formed at the center of the node of the first bag 11 by the dispersing means 50 and extending into the interior of the second bag 31, And a dispersion inducing portion 55 provided at a lower portion thereof.

The dispersion inducing portion 55 is formed in a conical shape gradually increasing in diameter from the upper portion to the lower portion. The dispersion inducing portion 55 collides with the oil discharged from the lower end of the first flow pipe 20 to disperse the oil widely into the second flow pipe 31. The oil introduced into the second bag 31 by the dispersion inducing portion 55 flows downward while being in contact with the second adsorbing layer 37.

The purification process using the filter described above will be briefly described.

The oil separated from the precipitate is introduced into the first bank 11 through the precipitation step. The fine suspended particles in the oil flowing into the first bank 11 are adsorbed by the first adsorption layer 17 and are primarily removed. When the oil continues to flow into the first bank 11 and the liquid level of the oil reaches the height of the upper end of the first flow pipe 20, the oil flows over the upper end of the first flow pipe 20 and flows through the first flow pipe 20). The oil flowing into the upper portion of the first flow pipe 20 flows into the second flow pipe 31 through the lower portion of the first flow pipe 20. At this time, the oil discharged through the lower portion of the first flow pipe 20 collides with the dispersion inducing portion 55 and is dispersed widely in the lateral direction along the inclined surface of the dispersion inducing portion 55.

The fine suspended particles in the oil flowing into the second bank 31 are adsorbed by the second adsorption layer 37 and are removed secondarily. When the oil continues to flow into the second bank 31 and the liquid level of the oil reaches the height of the upper end of the second flow pipe 40, the oil flows over the upper end of the second flow pipe 37 and flows into the second flow pipe 37 and is discharged to the outside.

Oil discharged to the outside through the second flow pipe (40) can be packed in a packaging container while being stored in a separate storage tank.

As described above, the present invention can effectively remove impurities by refining and refining milk after precipitation, thereby providing sesame oil and perilla oil with a clear and clear golden color.

Meanwhile, in the present invention, the steam and the fire can be sequentially added to the washed sesame using one heater, so that the above-described boiling step and the baking step can be continuously performed.

The conveyor 80 is installed so as to pass through the rear surface at the front surface of the housing 70. It is a matter of course that the conveyor 80 can be applied to a conventional sieve recognition, mesh type conveyor.

After putting sesame into the teaspoon 60, the teaspoon 60 is placed on the conveyor 80. The sorbet 60 passes through the interior of the housing at a constant speed by means of a conveyor.

The appearance of the teaspoon 60 is shown in Fig. The illustrated teaspoon 60 is composed of a rectangular frame portion 61 and a netting 65 provided inside the frame portion 61. The edge of the net 65 is joined to the inner surface of the rim 61 by welding or the like. The net body 65 has a mesh network structure having a plurality of eyes. The eyes of the netting 64 are formed smaller than the size of the sesame.

The wipes cleaned in the washing step are placed on the net 65 of the wiping tray 60 and spread widely. The sesame seeds must be spread over the netting 65 so that steam or fire can be evenly distributed to all the sesame seeds. It is preferable that the stack height of the sesame put on the net is 5 mm or less at maximum.

Referring again to FIG. 2, a steam chamber 71 is formed inside the housing 70. The steam chamber (71) is provided in the front portion of the housing (70).

The firebox injection pipe (95) can be installed under the firebox chamber (75). The firebox is supplied into the firebox chamber (75) through the firebox injection pipe (95).

It is needless to say that an exhaust fan can be installed on one side of the firebox chamber 75 so that moisture emitted from the firebox can be discharged to the outside while the sesame is burned in the firebox chamber 75.

The sesame seeds 60 are steamed by the conveyor 80 while passing through the steam chamber 71 while contacting the steam supplied through the spray nozzle 85. The time required for the trays to pass through the vapor chamber 71 is about 2 to 8 minutes.
