Description

Technical Field

[0001] This invention relates to a functional cutting board containing natural extracts and a method for manufacturing the same, and more specifically, to a functional cutting board comprising capsules containing grapefruit seed extract as a natural vitamin-containing extract and a method for manufacturing the same. Background Technology

[0002] Cutting boards are used to process ingredients when cooking food. In the past, cutting boards were commonly made from wood or plastic materials, mainly synthetic resins, reflecting their intended use and characteristics.

[0003] Plastic cutting boards have replaced existing wooden cutting boards, offering advantages such as non-absorption of moisture, light weight, and low manufacturing cost. However, they are easily scratched by cookware.

[0004] When scratches appear on the surface of a cutting board, bacteria multiply between the scratches, and pigments from food ingredients are absorbed, causing the surface of the cutting board to change color.

[0005] Therefore, it has antibacterial, antifungal, and bactericidal functions against bacteria that grow due to residual food components on the surface of the cutting board, and prevents damage to the coating due to knife scratches, thereby reducing the need for cutting boards with these antibacterial, antifungal, and bactericidal functions. Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] This invention is designed to solve the aforementioned problems and simultaneously provides functional, hygienic, and health-promoting effects. It is a functional extract containing natural extracts of vitamins, offering excellent economy and practicality in both manufacturing and use. The objective is to provide a cutting board and a method for manufacturing the same.

[0008] Methods for solving problems

[0009] A functional cutting board according to an embodiment for solving the above problems includes a base layer containing TPU (thermoplastic polyurethane) and a functional material contained in the base layer, wherein the functional material includes natural extracts containing vitamins.

[0010] In addition, natural extracts may include grapefruit seed extract.

[0011] In addition, the base layer comprises multiple capsules, each containing a natural extract, and the natural extract may include at least one of the following: antibacterial, antifungal, antiviral, or antioxidant substances.

[0012] In addition, each of the multiple capsules has a core-shell structure, and the core-shell structure may include a core containing natural extracts and a shell containing polymer resin.

[0013] In addition, natural extracts may include grapefruit seed extract.

[0014] Alternatively, core-shell capsules can be manufactured by extracting grapefruit seeds and then hot-pressing the extracted grapefruit seed extract to form a core.

[0015] Invention Effects

[0016] According to one embodiment of the functional cutting board, a natural extract, such as grapefruit seed extract containing vitamins, is encapsulated and protected in a core-shell structure to prevent loss of active ingredients (vitamins, etc.) during manufacturing and storage, and the natural extract contained within the base layer can maintain the function of the grapefruit seed extract without causing the coating layer to peel off.

[0017] Furthermore, when the shell is damaged, natural extracts are released and exert antibacterial, antifungal, antiviral, and antioxidant effects. These are characteristics of grapefruit seed extract, which delivers antibacterial and antioxidant components through food ingredients, thus benefiting health. Effectively eliminating bacteria that may arise from residual food ingredients can promote hygiene management.

[0018] In addition, the natural properties of grapefruit seed extract can provide an environmentally friendly functional cutting board, preventing toxicity and environmental pollution problems. Attached Figure Description

[0021] Figure 1 This is a schematic cross-sectional view of a functional cutting board containing natural extracts according to an embodiment of the present invention. Figure 2 This is a schematic cross-sectional view of a functional cutting board containing natural extracts according to another embodiment of the present invention.

[0022] Reference Figure 1 The functional cutting board 10 performs the functions of a cutting board body and includes a base layer 110 containing thermoplastic polyurethane (TPU, 111) and a functional material 112 contained within the base layer 110. Furthermore, the functional material 112 includes natural extracts containing vitamins.

[0023] Thermoplastic polyurethane (TPU, 111) is the basic component of the functional cutting board (10) of this invention. TPU (111) has excellent mechanical strength and elastic properties, and has heat resistance above 100°C. It can be washed in a dishwasher, and the functional cutting board 10 will not be damaged even when washed at high temperatures. TPU can be used without particular restrictions, as long as it is commonly used in industry. TPU can also be used by molding the raw material into granules or pellets.

[0024] The base layer 110 may include a functional material 112, which comprises a natural extract containing vitamins. In some embodiments, the natural extract may also contain at least one of an antibacterial substance, an antifungal substance, an antiviral substance, or an antioxidant. The natural extract may include grapefruit seed extract (GSE). Grapefruit seed extract may contain vitamins and may also contain antibacterial, antifungal, antiviral, or antioxidant substances.

[0025] Grapefruit seed extract is an extract obtained from grapefruit seeds, specifically by extraction with water, ethanol, or glycerol. This grapefruit seed extract possesses strong antibacterial, antifungal, antioxidant, and antiviral properties. It exhibits antibacterial activity against bacteria such as Escherichia coli, Staphylococcus aureus, Candida albicans, and Salmonella, and antifungal activity against fungi such as Candida and other molds. It also demonstrates effective antiviral activity, reducing the replication of certain types of viruses.

[0026] Furthermore, grapefruit seed extract is a non-toxic, non-metallic, odorless natural organic mixture that is non-corrosive and highly thermally stable, thus causing no environmental pollution. In addition, grapefruit seed extract has strong bactericidal and antiviral effects against bacteria, molds, viruses, and other spoilage or pathogenic microorganisms, and possesses excellent antioxidant properties, preventing rancidity of fatty acids and inhibiting the formation of rancid odors on cutting boards. It also exhibits excellent antibacterial, antifungal, antioxidant, and antiviral effects on leftover food.

[0027] Additionally, grapefruit seed extract has the same effects, but it is completely broken down even after being absorbed into the body. Therefore, there is no risk of toxicity due to accumulation in the body, making it a very safe natural extract for humans and animals.

[0028] In addition, grapefruit seed extract may contain vitamin C and vitamin E. It may also contain amino acids, fatty acids, tocopherols, and polyphenols. Grapefruit seed extract is an antioxidant compound containing polyphenols, vitamin C, and possibly vitamin E and bioflavonoids. Therefore, grapefruit seed extract, containing antioxidant compounds that act as immune enhancers, provides beneficial components to the body even when ingested. It not only offers antibacterial, antifungal, and antiviral effects but also provides beneficial components. However, it does have health effects.

[0029] In some embodiments, the functional material 112 may be contained in the base layer 110 in capsule form. Specifically, the base layer 110 comprises a plurality of capsules, and each of the plurality of capsules may contain a natural extract.

[0030] In some embodiments, each of the plurality of capsules may have a core-shell structure, and the core-shell structure may include a core containing a natural extract and a shell containing a polymer resin. The natural extract contained in the core may include grapefruit seed extract, and the polymer resin contained in the shell may include at least one of alginate, gelatin, and chitosan.

[0031] In some embodiments, the core-shell capsule can be manufactured by extracting grapefruit seeds and hot-pressing the extracted grapefruit seed extract at low temperature to form the core, but is not limited thereto. In some other examples, the core-shell capsule can be manufactured by extracting grapefruit seeds and mixing the extracted grapefruit seed extract with a polymer resin composition constituting the shell layer. Although not limited thereto, the core-shell structure can have a diameter of less than 10 μm, and the thickness of the shell portion can be less than 100 nm.

[0032] Because the natural extract of the present invention adopts a core-shell structure, the core contains the natural extract (grapefruit seed extract) and is protected by the shell, it can be used in the manufacturing process of the functional cutting board (10) or during the storage of the functional cutting board (10), thus preventing the loss of the natural extract (grapefruit seed extract). However, if it is necessary to release the natural extract, it is easy to release the natural extract due to damage to the shell.

[0033] Natural extracts contain vitamins and may also contain at least one of the following: antibacterial, antifungal, antiviral, or antioxidant substances. Additionally, natural extracts may contain antioxidant compounds, which may include at least one of polyphenols, vitamin C, vitamin E, or bioflavonoids.

[0034] The functional cutting board (10) according to the invention is coated with a natural extract, including grapefruit seed extract, on a base layer (110) that performs the main functions of the functional cutting board. This extract has antibacterial, antifungal, antiviral, and antioxidant properties. Because the coating peels off due to the use of the functional cutting board 10, rather than being contained within the base layer 110, the aforementioned functions (antibacterial, antifungal, antiviral, and antioxidant) are reduced. This is preventable.

[0035] Furthermore, when the natural extracts are blended with TPU to produce the base layer 110, a core-shell structure is used instead of the natural extracts themselves. Therefore, the core contains the natural extracts and is protected by a shell containing polymer resin. This prevents the loss of the natural extracts (grapefruit seed extract) due to manufacturing environment or conditions during the manufacturing of the cutting board.

[0036] Furthermore, as described below, during the manufacturing process of the functional cutting board 10, a core-shell structure capsule containing a natural extract (grapefruit seed extract) is manufactured and retained on the surface of the base layer 110. This allows the functional cutting board 10 to be used in a structure such that when the shell of the core-shell structure is damaged, the capsule ruptures, releasing the natural extract (grapefruit extract). Therefore, when food ingredients are prepared, the natural extract (grapefruit seed extract) contained in the core-shell structure capsule is released, and a portion of the natural extract (grapefruit seed extract) can be mixed into or delivered to the food ingredients. Therefore, applying a portion of the vitamin-containing natural extract (grapefruit seed extract) to food ingredients prepared using the functional cutting board 10 of this application can provide health benefits to those consuming the food ingredients.

[0037] Furthermore, when using the functional cutting board (10), the shell layer of the capsule core structure is broken with a knife, causing the capsule to rupture and release natural extracts (grapefruit seed extract). This damage effectively kills food residues on the functional cutting board (10) caused by viruses, bacteria, mold, etc. Therefore, the functional cutting board 10 is easy to manage and is economical because it does not require additional equipment for drying and sterilizing.

[0038] Hereinafter, a method for manufacturing a functional cutting board containing natural extracts according to embodiments of the present invention will be described.

[0039] First, a capsule with a core-shell structure containing natural extract 112 is manufactured. (S100)

[0040] The steps of manufacturing a core-shell structured capsule containing natural extract 112 include: preparing grapefruit seed extract; forming a core from the grapefruit seed extract prepared by hot pressing; and forming a core from the grapefruit seed extract prepared by hot pressing. This may include forming a shell layer containing a polymer resin on the core containing the extract.

[0041] Specifically, the steps for producing grapefruit seed extract involve extracting substances with antibacterial, antifungal, antiviral, and antioxidant functions from grapefruit. For example, one method for extracting grapefruit seed extract involves adding dried, crushed grapefruit to 99.9% ethanol and extracting twice at room temperature, 24 hours each time. The extract is then filtered, and the filtrate is concentrated under reduced pressure to obtain the grapefruit extract. This yields a seed ethanol extract. Another method involves adding distilled water to dried, crushed grapefruit and repeating hot water extraction twice at 90℃–95℃, 6 hours each time. The extract is then centrifuged at 10000×g for 30 minutes, and the resulting supernatant is called the grapefruit thermal extract. This also yields an aqueous extract.

[0042] Next, the prepared grapefruit seed extract can be heat-compressed to form the core. The vitamins in grapefruit seed extract may decompose at high temperatures. Therefore, the heat compression of grapefruit seed extract can be carried out at a low temperature of 40-70°C. Because the heat compression is performed within this temperature range, the natural components of the grapefruit seed extract contained in the core may not decompose. Heat-stabilizing agents can be used to perform the heat compression process to prevent the decomposition of natural substances (vitamins, etc.).

[0043] Next, in the step of forming a shell layer containing polymer resin on the core containing hot-pressed grapefruit seed extract, the shell layer composition is prepared by dissolving the polymer resin in water, and the shell layer composition and grapefruit seed extract are mixed at high speed to form the shell layer. The grapefruit seed extract is dispersed into small droplets by emulsification through stirring (500-2000 rpm) or ultrasonic treatment, and the core material containing grapefruit seed extract is added thereto. The shell layer can then be uniformly distributed within the composition. Next, the mixture is cooled to 10-15°C and the pH is adjusted to prepare capsules with a core-shell structure.

[0044] In the manufacturing step of the core-shell structure, the shell composition and grapefruit seed extract can be mixed at 10-30% by weight, 70-90% by weight, preferably 20-30% by weight, and 70-80% by weight respectively.

[0045] Next, a base layer 110 is formed comprising a core-shell structured capsule containing TPU 111 and natural extract 112. (S200)

[0046] Specifically, the base layer 110 can be formed by mixing TPU 111 with a capsule having a core-shell structure containing natural extracts 112 (including grapefruit seed extract).

[0047] In some embodiments, the base layer 110 may be manufactured using a base layer composition comprising 75% by weight of TPU, 23% by weight of a core-shell structured capsule containing natural extract 112, and 2% by weight of a dispersant. In some embodiments, the dispersant may be a mixture of zinc stearate and stearic acid in a 1:1 ratio.

[0048] In some embodiments, the materials are placed in a mixer and stirred for 40 minutes to ensure uniform mixing, then dried at 80°C for 3 hours, and the dried composition is then placed in a prepared container. A molding machine is used to manufacture the base layer 110. This is possible.

[0049] Since the core-shell structured capsules are contained together with the TPU in the base layer composition, capsules containing natural extracts can be contained within the base layer 110. Therefore, after the manufacturing of the functional cutting board 10 is completed, the loss of natural extracts within the functional cutting board 10 during dispensing can be prevented.

[0050] In some other embodiments, the core-shell structured capsules are mixed with a base composition, the mixed base composition is applied to a mold, and then the base composition is dried using an applicator or sprayer. The core-shell structure can be additionally added (sprayed) onto the base composition. The core-shell structured capsules applied to the base composition can be the same as those mixed in the base composition. Since the core-shell structured capsules are additionally sprayed onto the coated base composition, drying occurs simultaneously with the distribution of the core-shell structured capsules on the surface, so that after drying, impurities deposited on the base layer (110) by the core-shell structured capsules can be uniformly retained on the surface. Therefore, when using the functional cutting board (10), the amount of residual core-shell structured capsules on the surface is greater and more uniformly distributed, making it easier to release antioxidants, antibacterial substances, antifungal substances, or antiviral substances. Removing the substances with a knife can improve the antibacterial function of the functional cutting board 10.

[0052] Figure 2 This is a schematic cross-sectional view of a functional cutting board 10 according to another embodiment of the present invention. For ease of explanation, the details are omitted. Figure 1 This section describes the same functions as the functional cutting board 10, and also explains the differences. The main purpose is to provide an explanation.

[0053] Reference Figure 2 According to another embodiment of the present invention, the functional cutting board 10 further includes a coating 120 disposed on the surface of the base layer 110.

[0054] The coating layer 120 may include a core-shell capsule, and the core-shell capsule may be the same as the core-shell capsule contained in the base layer 110. The base layer 110 is also provided with a coating layer 120 containing a core-shell capsule of a natural extract (grapefruit seed extract), such that the grapefruit seed extract is deposited on the core shell when the functional cutting board 10 is used. Due to easier release from the shell capsule, the antioxidants (polyphenols, vitamin C, vitamin E, bioflavonoids) contained in the grapefruit seed extract can be easily transferred to the food ingredients.

[0055] The coating 120 can be manufactured by making the base layer 110 described above, and then spraying a coating composition containing a core-shell structure capsule containing grapefruit seed extract onto the surface or upper surface of the base layer 110.
