Description

Technology Field

[0001] The present invention relates to a method for manufacturing perilla seed oil and perilla seed oil manufactured by the method, and more specifically, to a method for manufacturing degassed germinated perilla seed oil and degassed germinated perilla seed oil. Background Technology

[0002] Perilla oil is a vegetable oil obtained by pressing perilla seeds. Perilla oil pressed from roasted perilla seeds has a distinctive nutty flavor, so it is used to enhance the flavor of Korean cuisine or as cooking oil. Raw perilla oil pressed from unroasted perilla seeds is not consumed but is used for lamps or for weaving objects.

[0003] Sesame oil is extracted by pressing sesame seeds. There are two methods of extraction: the hot-press method and the cold-press method. Generally, the hot-press method is used to produce sesame oil, which is made by roasting sesame seeds at a temperature higher than 210 degrees Celsius to activate the fat before pressing. Oil extracted using the hot-press method has a darker color and a more intense, distinctive flavor. It is not refined to preserve this unique flavor. Furthermore, because it has low smoke and ignition points, heating it to high temperatures can generate carcinogens, making it unsuitable for deep-frying.

[0004] Edible oils such as perilla oil and sesame oil are packaged in sealed containers; when the lid is opened, air enters the container and comes into contact with the oil, causing rancidity that is harmful to health. Rancidity is a phenomenon in which organic substances, such as alcohol or fats, are hydrolyzed or oxidized by the action of oxygen in the air, light, heat, bacteria, or enzymes to form various oxidized compounds, including fatty acids, resulting in changes in taste and color and the emission of an unpleasant odor.

[0005] However, because perilla oil has a structure susceptible to rancidity and oxidation, it should be used as is for dishes that do not require heat, such as seasoned salads or bibimbap. It should also be stored in a dark, cool, and dry place and consumed as soon as possible after opening to ensure the oil is in a healthy state.

[0006] Perilla oil is an omega-3 essential fatty acid containing a large amount of alpha-linolenic acid. Perilla oil typically has a shelf life of about one year, but the direct cause of rancidity is the frequent opening of the container lid. Increased contact with air due to frequent opening accelerates rancidity. To prevent this rancidity, freshly pressed perilla oil is divided into brown beverage bottles sterilized with boiling water and stored in the refrigerator, or a small amount of sesame oil, which has a longer shelf life than perilla oil, is added.

[0007] Sesame oil contains unsaturated fatty acids such as linoleic acid and linolenic acid, which have excellent effects on health and beauty. It lowers blood cholesterol levels, improves blood vessel elasticity to prevent hardening, and helps prevent arteriosclerosis. Additionally, it aids in metabolism and brain activity. The protein in sesame seeds contains essential amino acids, making it highly nutritious, and it is rich in Vitamin E, which prevents aging. However, since sesame oil spoils easily when exposed to air and sunlight, it should ideally be stored in a bottle with a small opening, tightly sealed with a stopper, in a well-ventilated, dry place free from temperature fluctuations.

Additionally, throughout this specification, the same components are described using the same reference numerals.

[0033] Furthermore, the components of the embodiments described with reference to each drawing are not limited to the respective embodiments and may be implemented to be included in other embodiments within the scope of maintaining the technical spirit of the present invention. It is also obvious that multiple embodiments may be re-implemented as a single embodiment that integrates multiple embodiments, even if a separate description is omitted.

[0034] FIG. 1 is a diagram illustrating a flowchart of a method for manufacturing perilla seed oil according to the present invention, and FIG. 2 is a block diagram showing the configuration of a perilla seed oil manufacturing apparatus (100) implementing the method for manufacturing perilla seed oil according to the present invention.

[0035] Referring to FIG. 1, the method for producing perilla oil according to the present invention includes the step of pressing sesame seeds to extract oil (S110), the step of degassing the extracted oil using a degassing machine (S120), and the step of putting the degassing oil into a bottle and packaging it (S130).

[0036] Both perilla and sesame seeds can be used for pressing oil. Sesame is an annual plant of the Sesamaceae family native to India and Africa, while perilla is an annual plant of the Lamiaceae family native to Southeast Asia. Since they are fundamentally different species, sesame and perilla naturally differ slightly in appearance and properties.

[0037] Referring to FIG. 2, the perilla oil manufacturing apparatus (100) according to the present invention may include an oil press (110) and a deaerator (120). The deaerator (120) may include an oil storage container (125) and a vacuum device (127).

[0038] An oil press (or oil press) (110) can extract oil by pressing perilla seeds or sesame seeds (S110). Oil can be extracted using a screw oil press or a hydraulic oil press. Although it is common to roast perilla seeds or sesame seeds at a high temperature of 100 degrees or higher before extracting oil, oil can also be extracted by pressing directly at room temperature without roasting. Roasted oil is also called roasting oil.

[0039] Next, the squeezed oil can be injected into the container of the degasser (120) to be degassed.

[0040] Degassing refers to the removal of air bubbles generated during the manufacturing process of liquid products such as food, pharmaceuticals, and cosmetics.

[0041] The degassing machine (120) can continuously remove bubbles in a liquid under vacuum.

[0042] For example, the deaerator (120) may include an oil storage container (125) and a vacuum device (127). An inlet pipe and an outlet pipe may be connected between the oil storage container (125) and the vacuum device (127). The oil storage container (125) may have a capacity of about 4 liters.

[0043] Oil to be degassed is injected into the oil storage container (125) of the degasser (120), and the vacuum device (127) is operated. The vacuum device (127) creates vacuum pressure in the oil, thereby removing air bubbles inside the oil. It is desirable to perform the degassing process several times continuously to almost completely remove air bubbles inside the oil.

[0044] The degassed oil can generally be placed in a glass bottle, sealed, and stored at room temperature. In the degassing step (S120), the degasser can inject the extracted oil into the degasser and degas it 3 to 6 times.

[0045] The degassing process may vary depending on the type of oil and whether it is roasted, but the degassing process can be performed 3 to 6 times. One degassing process refers to the process in which all the oil in the oil storage container flows into the vacuum device to be degassed and circulated.

[0046] When degassing roasted oil, the number of degassing cycles may be reduced compared to when degassing raw oil. This is because the rate of rancidity progression in roasted oil is slower than in raw oil.

[0047] In the oil extraction step (S110), the sesame seeds may be germinated perilla seeds.

[0048] Sprouted perilla is perilla that has sprouted and been dried, and it is mainly used in the form of ground powder. Sprouted perilla extracted without roasting becomes sprouted raw perilla oil, and sprouted raw perilla oil becomes degassed sprouted raw perilla oil when degassed.

[0049] In addition, in the oil extraction step (S110), the oil extractor (110) may extract oil by roasting perilla seeds.

[0050] In other words, roasted perilla oil can be obtained by roasting dried perilla seeds at a temperature of 200 degrees or higher and then extracting the oil.

[0051] And, in the oil extraction step (S110), the sesame seeds may include sprouted sesame seeds and roasted sesame seeds.

[0052] That is, dried sprouted perilla seeds can be mixed with unroasted and roasted seeds in a predetermined ratio and then extracted. Then, perilla oil mixed with sprouted raw perilla oil and roasted perilla oil in a predetermined ratio can be obtained.

[0053] To evaluate the quality of dehydrated sprouted cold-pressed perilla oil, tests were commissioned to the Food Analysis Research Center at Suwon Women's University.

[0054] Table 1 below shows the rancidity progression rate of degassed raw perilla oil compared to ungassed raw perilla oil as a result of the test.

[0055] Sanga (24.10.08.) Sanga (24.10.22.) Peroxide value (24.10.08.) Peroxide value (24.10.22.) Dehydrated sprouted raw perilla oil 1.22 1.42 1.9 30.0 Sprouted raw perilla oil 1.19 1.53 2.1 43.3 Sprouted cold-pressed perilla oil + Roasted perilla oil (5:5) 1.3 1.61 2.5 45.8 Roasted perilla oil 1.36 1.60 1.4 32.8

[0056] To analyze the quality of perilla oil, changes in the values ​​of Free Fatty Acid Value (FFA) and Peroxide Value (POV) were measured. The acid value and peroxide value are key indicators representing the freshness of the oil and the degree of rancidity.

[0057] For four types of perilla oils produced on October 2, 2024—dehydrated sprouted raw perilla oil, sprouted raw perilla oil, perilla oil mixed equally with sprouted raw perilla oil and roasted perilla oil, and roasted perilla oil—the acid value and peroxide value were measured on October 8, 2024 and October 22, 2024, respectively.

[0058] As shown in Table 1, after 6 days from the date of manufacture, the degassed sprouted raw perilla oil had an acid value of 1.22 and a peroxide value of 1.9, exhibiting the lowest acid value and peroxide value compared to other ungassed perilla oils. Therefore, it can be seen that the initial quality of the degassed sprouted raw perilla oil is the best.

[0059] After 20 days from the date of manufacture, the degassed sprouted raw perilla oil had an acid value of 1.42 and a peroxide value of 30.0, showing the lowest level of rancidity progression compared to other ungassed perilla oils. Therefore, it can be seen that the degassed sprouted raw perilla oil has the slowest rate of rancidity progression and maintains its freshness for the longest time.

[0060] Referring again to Table 1, it can be seen that the rate of increase in the peroxide value (POV) of degassed sprouted raw perilla oil is lower than that of other products, indicating that the rate of rancidity is relatively slow, and it exhibits oxidation resistance similar to that of roasted perilla oil, showing excellent quality retention even without roasting.

[0061] When comparing the increase in peroxide value during the period from October 8, 2024 to October 22, 2024, degassed sprouted raw perilla oil showed an increase from 1.9 to 30.0 (+28.1), sprouted raw perilla oil (100%) showed an increase from 2.1 to 43.3 (+41.2), 50:50 mixed oil of sprouted raw perilla oil and roasted perilla oil showed an increase from 2.5 to 45.8 (+43.3), and roasted perilla oil showed an increase from 1.4 to 32.8 (+31.4).

[0062] Through the results of Table 1, it can be confirmed that the rancidity inhibition effect is significant thanks to the degassing process, and that the oil is of excellent initial quality even without roasting.

[0063] According to the method for manufacturing perilla seed oil of the present invention, the storage period can be increased by significantly reducing the rate of rancidity by degassing and sealing the perilla seed oil several times.

[0064] The method for producing perilla seed oil according to the present invention demonstrates the excellence of degassed germinated raw perilla seed oil, and it can be seen that the initial quality is very excellent and the freshness is high. In addition, the rate of rancidity progression is relatively slow, so it can be evaluated as a stable oil, and it is competitive in the market as an oil that can maintain high quality without a roasting process.

[0065] Although an embodiment of the present invention has been described above, those skilled in the art may modify and change the present invention in various ways by adding, changing, deleting, or adding components, etc., without departing from the spirit of the present invention as described in the claims, and such modifications and changes are also to be considered to be included within the scope of the rights of the present invention.
