Description
Dog gum for oral care of companion dogs
[0001] The present invention relates to a dog chew for oral care of companion dogs, and more specifically, to a dog chew for oral care of companion dogs that not only helps maintain the dental health of companion dogs, but also effectively removes tartar and is also highly preferred.
[0002] In recent years, as the nuclear family system has become more widespread, there has been an increase in the number of cases where pets such as dogs and cats are raised with family members at home rather than outside the home.
[0003] According to recent research, the pet-related market has been growing annually, reaching KRW 900 billion in 2012, KRW 1.8 trillion in 2015, and KRW 2.3 trillion in 2016. It is projected to reach KRW 6 trillion by 2027. This rapid growth, coupled with the low birth rate and aging population, is attributed to this market.
[0004] Meanwhile, the demand for pet food is growing the fastest in recent years, and dog gum is a representative pet food item for the health and entertainment of pets.
[0005] Dog chews are designed as toys and treats for dogs to chew and eat. They also have a tartar-removing function, which helps maintain dental health and relieves boredom and stress. Dog chews are especially beneficial when your dog's gums become itchy due to teeth grinding or when they're stressed, as they can prevent chewing on other objects.
[0006] Accordingly, dog chews, which are essential for raising companion dogs, have been manufactured in various ways, and in particular, considering that companion dogs bite them with their teeth and produce a bad smell in their stool after ingesting dog chews, various dog chews that take into consideration the dental health of companion dogs are being proposed.
[0007] The present invention has been devised with the above points in mind, and its purpose is to provide a dog gum for oral care of dogs that not only helps maintain the dental health of companion dogs, but also effectively removes tartar and has a high preference.
[0008] In order to solve the above-described problem, the dog gum for oral care of companion dogs of the present invention contains an extract of evening primrose seed.
[0009] In a preferred embodiment of the present invention, the evening primrose seed extract may be prepared through a supercritical carbon dioxide extraction method.
[0010] In a preferred embodiment of the present invention, the evening primrose seed extract may be prepared by drying evening primrose seeds at a temperature of 60 to 80°C for 5 to 9 hours, grinding them to prepare evening primrose seed powder having a particle size of 40 to 60 mesh, and extracting the prepared evening primrose seed powder using a supercritical carbon dioxide extraction method at a temperature of 35 to 55°C and a pressure of 20 to 40 MPa for 90 to 210 minutes.
[0011] In a preferred embodiment of the present invention, the dog gum for oral care of companion dogs may further include ground beef, soy protein, sodium alginate, tapioca starch, carrageenan, rice flour, and honey.
[0012] In a preferred embodiment of the present invention, the dog gum for oral care of companion dogs of the present invention may contain 5 to 15 parts by weight of evening primrose seed extract per 100 parts by weight of ground beef.
[0013] The dog gum for oral care of companion dogs of the present invention not only helps maintain the dental health of companion dogs, but also effectively removes tartar and is also highly palatable.
[0014] Figure 1 is a graph showing an analysis of whether the evening primrose seed extract prepared in Preparation Example 1 has bone regeneration efficacy through increased expression of bone formation markers.
[0015] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description have been omitted for clarity of description, and the same reference numerals are assigned to identical or similar components throughout the specification.
[0016]
[0017] The dog gum for oral care of companion dogs of the present invention contains evening primrose seed extract.
[0018] Evening primrose, native to South America, has become a naturalized plant in North America, Korea, Japan, and China, where it grows abundantly along watersides, roadsides, and rice fields. Its scientific name is Oenothera odorata Jacquin. Its name comes from its wine-like aroma and its attraction to wild animals. The name "evening primrose" comes from its habit of blooming at night to greet the moon. It grows upright, 50–90 cm tall, and its stems are densely covered with fine hairs. The rosettes that grow from the roots spread out in a rosette shape, while the leaves on the stems are alternate, broadly linear, 5–15 cm long and 5–12 mm wide. The tips are pointed, the bases touch the stem, and the edges are shallowly serrated. They are dark green with a white midrib. The flowers are yellow, blooming singly in the upper leaf axils, opening in the evening and withering in the morning. They have a slightly reddish tint. The fruit is a club-shaped capsule, 2 to 3 cm long, and split into four lobes. The seed oil is used as a folk remedy for diabetes, and the whole plant is used medicinally to reduce fever.
[0019] Specifically, the evening primrose seed extract may be manufactured through a supercritical carbon dioxide extraction method.
[0020] More specifically, the evening primrose seed extract may be manufactured by drying evening primrose seeds, grinding them to manufacture evening primrose seed powder, and extracting the manufactured evening primrose seed powder using a supercritical carbon dioxide extraction method.
[0021] Most preferably, the evening primrose seed extract may be prepared by drying evening primrose seeds at a temperature of 60 to 80°C, preferably 65 to 75°C, for 5 to 9 hours, preferably 6 to 8 hours, then grinding the seeds to prepare evening primrose seed powder having a particle size of 40 to 60 mesh, preferably 45 to 55 mesh, and extracting the prepared evening primrose seed powder through a supercritical carbon dioxide extraction method at a temperature of 35 to 55°C, preferably 40 to 50°C, and a pressure of 20 to 40 MPa, preferably 25 to 35 MPa, for 90 to 210 minutes, preferably 120 to 180 minutes. By preparing the evening primrose seed extract by satisfying these conditions, it can not only help maintain the dental health of companion dogs, but also effectively remove tartar and is also a highly palatable oral care product for companion dogs. You can make dog gum.
[0022] Additionally, the dog chew for oral care of companion dogs of the present invention may further include ground beef. In this case, the ground beef may be a lean cut of beef, preferably rump.
[0023] Meanwhile, the dog gum for oral care of companion dogs of the present invention may contain 5 to 15 parts by weight, preferably 8 to 12 parts by weight, of evening primrose seed extract per 100 parts by weight of ground beef. If it contains less than 5 parts by weight, there may be a problem that the dog's dental health effect and / or tartar removal effect may be reduced, and if it contains more than 15 parts by weight, there may be a problem that the dog's preference may be reduced.
[0024] Furthermore, the dog gum for oral care of companion dogs of the present invention may further include at least one selected from soy protein, sodium alginate, tapioca starch, carrageenan, rice flour, and honey, and preferably may further include soy protein, sodium alginate, tapioca starch, carrageenan, rice flour, and honey.
[0025] Soy protein is a protein extracted from soybeans. After extracting soybean oil using the organic solvent hexane, the residue is called "defatted soybeans." After removing all of this fat, the remaining protein and carbohydrates are removed. From these defatted soybeans, non-proteins such as soluble and insoluble carbohydrates are removed, and this is called "soy protein." In other words, soy protein can be said to be a condensation of pure soybean protein by removing the fat and carbohydrates from soybeans.
[0026] The dog gum for oral care of companion dogs of the present invention may contain 70 to 90 parts by weight, preferably 75 to 85 parts by weight, of soy protein per 100 parts by weight of ground beef.
[0027] Sodium alginate is a food additive that is included in foods to increase adhesiveness and viscosity, promote emulsion stability, and improve the physical properties and texture of foods.
[0028] The dog gum for oral care of companion dogs of the present invention may contain 30 to 50 parts by weight, preferably 35 to 45 parts by weight, of sodium alginate per 100 parts by weight of ground beef.
[0029] The starch extracted from cassava roots is called "tapioca," and tapioca starch is its main ingredient. The round, soft balls in Taiwanese bubble tea are made from tapioca. Tapioca is also widely used in everyday foods, typically as a thickener or bulking agent in processed foods, or as an ingredient in alcohol.
[0030] The dog gum for oral care of companion dogs of the present invention may contain 40 to 60 parts by weight, preferably 45 to 55 parts by weight, of tapioca starch per 100 parts by weight of ground beef.
[0031] Carrageenan is a complex polysaccharide extracted from red algae grown in clean waters. It is a versatile gelling agent ideal for use in foods and food systems. It can also be incorporated into foods as a dispersing and emulsifying stabilizer, swelling and thickening agent, binder, dietary fiber, anti-crystallizer, or gelling agent.
[0032] The dog gum for oral care of companion dogs of the present invention may contain 1 to 15 parts by weight, preferably 8 to 12 parts by weight, of carrageenan per 100 parts by weight of ground beef.
[0033] In addition, the dog gum for oral care of companion dogs of the present invention may contain 10 to 20 parts by weight, preferably 13 to 17 parts by weight, of rice powder per 100 parts by weight of ground beef.
[0034] In addition, the dog gum for oral care of companion dogs of the present invention may contain 1 to 10 parts by weight of honey, preferably 2 to 5 parts by weight, per 100 parts by weight of ground beef.

[0037]
[0038] Preparation Example 1: Preparation of evening primrose seed extract
[0039] (1) Washed evening primrose seeds were dried at a temperature of 70℃ for 7 hours, then ground to produce evening primrose seed powder having a particle size of 50 mesh.
[0040] (2) The manufactured evening primrose seed powder was placed in a supercritical carbon dioxide extraction device, and extracted for 150 minutes under conditions of a temperature of 45°C and a pressure of 30 MPa to manufacture an evening primrose seed extract.
[0041]
[0042] Experimental Example 1: Analysis of bone regeneration efficacy through increased expression of bone formation markers.
[0043] The effect of the evening primrose seed extract prepared in Preparation Example 1 on bone regeneration was analyzed by increasing the expression of osteogenic markers. For this analysis experiment, bone marrow-derived mesenchymal stem cells (BMSCs) were cultured in 2D monolayer and 3D spheroid, respectively, and the osteogenic differentiation of the cells was evaluated by treating them with various concentrations of evening primrose seed extract.
[0044] Gene expression of ALP, OCN, OPN, OSX, and RUNX2 was analyzed as bone formation markers, and after 7 days of culture, the expression of each marker was measured through quantitative reverse transcription PCR (qRT-PCR) and is shown in Figure 1.
[0045] As can be seen in Fig. 1, in the group treated with the evening primrose seed extract prepared in Preparation Example 1, the expression of ALP, OCN, OPN, OSX, and RUNX2 showed a significant increase in a concentration-dependent manner, and in particular, the greatest increase in expression was observed at a concentration of 20 μM. In addition, it was confirmed that the expression of bone formation markers significantly increased in 3D spheroid culture. From these results, it was confirmed that the evening primrose seed extract prepared in Preparation Example 1 can play an important role in promoting bone formation.
[0046] In conclusion, it was confirmed that the evening primrose seed extract prepared in Preparation Example 1 can help dogs maintain dental health when consumed.
