[0015] 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.

[0016] Reference Figure 1 The functional cutting board 10 performs the function 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. The functional material 112 includes grapefruit extract.

[0017] 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.

[0018] The base layer 110 may include a functional material 112 containing a grapefruit extract containing vitamins. In some embodiments, the functional material may also include at least one of an antibacterial material, an antifungal material, an antiviral material, or an antioxidant material.

[0019] Grapefruit extract may include grapefruit seed extract (GSE) and grapefruit peel extract. Grapefruit seed extract may contain vitamin C, naringin, hesperidin, and beta-carotene, while grapefruit peel extract may contain naringin, apigenin, and pectin.

[0020] In addition, grapefruit seed extract and / or grapefruit peel extract may also contain vitamins other than vitamin C, antibacterial substances, antifungal substances, antiviral substances, or antioxidants.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] Meanwhile, grapefruit peel extract, extracted from grapefruit peel, has anti-inflammatory and anti-cancer effects, including inhibiting inflammation and cancer cells, and is known to be beneficial to health, such as helping the growth of beneficial cells. Intestinal bacteria, when ingested, can promote digestion.

[0026] Meanwhile, the grapefruit peel mentioned in this instruction manual refers to the endocarp of the grapefruit, which fills the space between the seeds (pulp) and the hard outer peel. While the grapefruit peel is also rich in functional components such as dietary fiber, this is to rule out the possibility of pesticide residues even after thorough washing.

[0027] 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.

[0028] 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 grapefruit seed extract contained in the core may consist of vitamin C, naringin, hesperidin, and beta-carotene, and the grapefruit peel extract may consist of naringin, apigenin, and pectin.

[0029] The polymer resin contained in the shell may include at least one of alginate, gelatin and chitosan.

[0030] In some embodiments, the core-shell capsule can be manufactured by preparing grapefruit seed extract and grapefruit peel extract, and forming the core from the grapefruit seed extract and grapefruit peel extract prepared by low-temperature hot pressing, but this is the only possible method. In some other embodiments, the core-shell capsule can be manufactured by mixing grapefruit seed extract and grapefruit peel 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.

[0031] Because the natural extract of this invention adopts a core-shell structure, with the core containing the natural extract (grapefruit extract) and protected by the shell, it can be used in the manufacturing process of functional cutting boards (10) or during the storage of the functional cutting board (10), preventing the loss of the natural extract (grapefruit extract). However, if it is necessary to release the natural extract, it can be easily released due to damage to the shell.

[0032] Meanwhile, when using a core-shell structure, in terms of encapsulation process yield, the preferred weight ratio of grapefruit seed extract to grapefruit peel extract contained in the core is 10:1 to 10:2.

[0033] The functional cutting board (10) according to the present invention has the following structure: a base layer (110) performing the main functions of the functional cutting board is coated with natural extracts, including grapefruit extract which has antibacterial, antifungal, antiviral and antioxidant effects. Conversely, by being contained within the base layer 110, the coating peels off due to the use of the functional cutting board 10, thus reducing the aforementioned functions (antibacterial, antifungal, antiviral, and antioxidant). This can be prevented.

[0034] Furthermore, when the natural extract is mixed with TPU to produce the base layer 110, a core-shell structure is used instead of the natural extract itself. Therefore, the core contains the natural extract and is protected by a shell containing polymer resin. This prevents the loss of the natural extract (grapefruit extract) due to the manufacturing environment or conditions during the manufacturing of the cutting board.

[0035] Furthermore, as described below, during the manufacturing process of the functional cutting board 10, a core-shell structure capsule containing a natural extract (grapefruit extract) is manufactured and retained on the surface of the base layer 110. Thus, when the functional cutting board (when using 10 pieces) is used, the capsule can be broken open by using a knife to release the natural extract (grapefruit extract). Therefore, when preparing food ingredients, the natural extract (grapefruit extract) contained in the core-shell structure capsule is released, and some of the natural extract (grapefruit extract) can be mixed or delivered into the food ingredients. Therefore, some vitamin-containing natural extracts (grapefruit extract) are applied to food ingredients prepared using the functional cutting board 10 of this invention, thereby providing health benefits to those who consume the food ingredients.

[0036] Furthermore, when using the functional cutting board (10), the shell of the capsule core structure is broken with a knife, shattering the capsule and releasing the natural extract (grapefruit extract). This destruction effectively kills any food residue remaining on the functional cutting board (10). Therefore, the functional cutting board 10 is easy to manage and is economical because no additional equipment is required for drying and sterilizing it.

[0037] Hereinafter, a method for manufacturing a functional cutting board containing natural extracts according to embodiments of the present invention will be described.

[0038] First, a capsule with a core-shell structure containing natural extract 112 is manufactured. (S100)

[0039] The steps of manufacturing a core-shell structured capsule containing natural extract 112 may include: preparing a grapefruit extract; forming a core from the prepared grapefruit extract by heat compression; and forming a shell from the heat-compressed grapefruit extract. The core contains a polymer resin.

[0040] Specifically, the steps for preparing grapefruit extract may include extracting substances containing vitamin C, naringin, hesperidin, and beta-carotene from grapefruit seeds, and extracting substances containing naringin, apigenin, and pectin from grapefruit peel. For example, one method for extracting grapefruit seed / peel extract involves adding 99.9% ethanol to dried, pulverized grapefruit seeds / peel, extracting twice at room temperature for 24 hours each time, and filtering the extract. The resulting filtrate is then concentrated under reduced pressure to obtain the grapefruit / peel ethanol extract. Another method involves adding distilled water to dried, pulverized grapefruit seeds / peel, repeating hot water extraction twice at 90°C–95°C for 6 hours each time, and centrifuging the extract at 10000×g for 30 minutes to obtain the supernatant. You can also obtain a grapefruit seed / peel hot spring water extract.

[0041] Next, the prepared grapefruit seed extract and grapefruit peel extract can be hot-pressed to form the core. The vitamins in the grapefruit extract may decompose at high temperatures. Therefore, the hot compression of the grapefruit extract can be carried out at a low temperature of 40-70°C. Because the hot compression is performed within this temperature range, the natural components contained in the grapefruit extract within the core may not decompose. Heat-stabilizing agents can be used to perform the hot compression process to prevent the decomposition of natural substances (vitamins, etc.).

[0042] The next step, forming a shell layer containing polymer resin on the core containing hot-pressed grapefruit extract, involves dissolving the polymer resin in water to prepare a shell layer composition, mixing the shell layer composition with the grapefruit extract, and stirring at 100°C. Emulsification is performed at high speed (500-2000 rpm) or by ultrasonic treatment to disperse the grapefruit extract in the form of small droplets, ensuring that the core material containing the grapefruit extract is dispersed within the shell layer composition. This allows for uniform distribution. The mixture is then cooled to 10-15°C and the pH is adjusted to prepare capsules with a core-shell structure.

[0043] In the manufacturing step of the core-shell structure, the shell composition and grapefruit extract can be mixed at 10-30% by weight, 70-90% by weight, preferably 20-30% by weight, and 70-80% by weight, respectively.

[0044] Next, a base layer 110 is formed comprising a core-shell structured capsule containing TPU 111 and natural extract 112. (S200)

[0045] 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).

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0051] 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 point is to provide an explanation.

[0052] 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.

[0053] 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 extract), so that the grapefruit extract forms a core-shell structure when the functional cutting board 10 is used. Due to easier release from the capsule, the antioxidants (polyphenols, vitamin C, vitamin E, bioflavonoids) contained in the grapefruit extract can be easily transferred to the food ingredients.

[0054] The coating layer 120 can be manufactured by producing the base layer 110 described above, and then spraying a coating composition containing a core-shell structure capsule containing grapefruit extract onto the surface or upper surface of the base layer 110.
