{NUTRIENT COMPOSITION FOR IMPROVING JOINT HEALTH IN PET DOGS CONTAINING BOSWLLIA EXTRACT}

The present invention relates to a nutritional composition for improving joint health in dogs containing a Boswellia extract, and more specifically, to a nutritional composition for improving joint health in dogs containing a Boswellia extract, which is rich in nutrients beneficial to joints and improves joint health in dogs, and exhibits excellent palatability and storability.

In the past, animals such as dogs and cats that live with people were called 'pets' to mean animals that are kept to provide enjoyment to people, but recently, they are called 'companion animals' to mean that animals are like friends or family members who live with people and provide psychological stability and intimacy.

Pets are becoming more diverse, not only in the traditional pets like dogs and cats, but also in parrots, hedgehogs, rabbits, and hamsters. Recently, the level of affection shown toward pets has increased, and related industries for caring for pets are gaining attention.

Accordingly, the industry related to pet food and snacks is a field that is receiving more attention because it is directly related to the health of pets, and the trend is for pet food and snacks to approach the type similar to food consumed by humans. Biscuits, gum, jerky, and drinks that can be pet food or snacks are not only beneficial to the health of pets but can also reduce stress, so they are expanding into types that are more similar to human food.

In addition, recently, there has been an increase in consumer demand for products that go beyond simply providing nutrients for pet food and snacks to products that contain various functional ingredients to not only improve the health of pets but also have improved texture and flavor to suit their preferences.

In addition, as interest in companion animals increases and the quality of medical services improves, the life expectancy of companion animals is gradually increasing, and as the life expectancy of companion animals improves, the number of companion animals suffering from joint diseases is also gradually increasing. However, there has been a problem in that the development of feed, snacks, and nutritional supplements to improve these problems has not progressed.

Hereinafter, preferred embodiments of the present invention and the properties of each component will be described in detail. However, this is intended to be a detailed description to enable a person having ordinary skill in the art to which the present invention pertains to easily carry out the invention, and does not mean that the technical idea and scope of the present invention are limited thereby.

The nutritional composition for improving joint health of companion dogs containing a Boswellia extract according to the present invention comprises a sugar component, a Boswellia extract, cheese powder, glucosamine, propolis, zinc oxide, vitamin D3, ornithine hydrochloride, a safflower seed mixture, a herbal medicine for improving joints, a natural preservative, indigestible maltodextrin, and crystalline cellulose, and comprises 100 parts by weight of a sugar component, 1 to 3 parts by weight of a Boswellia extract, 5 to 10 parts by weight of a cheese powder, 3 to 5 parts by weight of glucosamine, 0.5 to 1 part by weight of propolis, 0.5 to 1 part by weight of zinc oxide, 0.01 to 0.1 parts by weight of vitamin _D3 , 0.1 to 0.5 parts by weight of ornithine hydrochloride, 3 to 5 parts by weight of a safflower seed mixture, 1 to 3 parts by weight of a herbal medicine for improving joints, 0.01 to 0.1 parts by weight of a natural preservative, It is preferably composed of 10 to 15 parts by weight of indigestible maltodextrin and 15 to 20 parts by weight of crystalline cellulose.

The above-mentioned sugar component serves to improve palatability by providing a sweet taste to the nutritional composition for improving joint health of companion dogs containing the Boswellia extract according to the present invention, and is preferably composed of at least one selected from the group consisting of anhydrous crystalline glucose, fructooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, maltooligosaccharide, xylooligosaccharide, gentioligosaccharide, and agave syrup, and is more preferably composed by mixing 5 to 10 parts by weight of at least one oligosaccharide selected from the group consisting of fructooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, maltooligosaccharide, xylooligosaccharide, and gentioligosaccharide with 100 parts by weight of anhydrous crystalline glucose.

The above anhydrous crystalline glucose not only adds sweetness, but also plays a role in improving the efficiency of the powdering process in the process of manufacturing the nutritional composition according to the present invention in powder form, and the fructooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, maltooligosaccharide, xylooligosaccharide, and gentiooligosaccharide are composed of components that provide sweetness but have a low absorption rate in the body, and thus play a role in improving the health of companion animals.

If the content of oligosaccharide is less than 5 parts by weight based on 100 parts by weight of the anhydrous crystalline glucose, the sweetness and palatability of the nutritional composition may be reduced, and if the content of oligosaccharide exceeds 10 parts by weight, the efficiency of the powdering process of the nutritional composition may be reduced.

The above Boswellia extract is contained in an amount of 1 to 3 parts by weight, and is preferably manufactured by mixing 500 to 1,000 parts by weight of ethanol having a mass concentration of 80 to 90% with 100 parts by weight of Boswellia, repeatedly extracting the mixture 2 to 4 times for 5 to 7 hours at a temperature of 65 to 75°C, and then filtering and concentrating under vacuum. The nutritional composition for improving joint health in dogs manufactured through the present invention has the effects of alleviating arthritis symptoms, enhancing immunity, anti-inflammation and anti-cancer, wound healing, muscle strengthening, headache prevention, and skin health promotion.

Boswellia refers to the frankincense of the frankincense tree, and the boswellia extract obtained by processing the resin of the frankincense tree contains β-boswellic acid, AKBA, and terpenoids. Among these, β-boswellic acid is related to preventing cartilage cell necrosis, promoting cartilage cell proliferation, and anti-inflammatory reactions, and thus shows the effect of promoting joint health in companion dogs.

The manufacturing process of the Boswellia extract carried out through the above process provides the Boswellia extract containing a large amount of the β-boswellic acid, thereby providing a Boswellia extract having an excellent effect of promoting joint health in companion dogs. However, if the content of the Boswellia extract is less than 1 part by weight, the effect is minimal, and if the content of the Boswellia extract exceeds 3 parts by weight, the effect is not significantly improved, while lowering the palatability of the nutritional composition and excessively increasing the manufacturing cost, which is not preferable.

The cheese powder is contained in an amount of 5 to 10 parts by weight, and is rich in various nutrients such as calcium and has excellent palatability while being rich in nutrients, and serves to provide a nutritional composition that shows the effect of improving the joint health of companion dogs.

If the content of the above cheese powder is less than 5 parts by weight, the above effect is minimal, and if the content of the above cheese powder exceeds 10 parts by weight, the above effect is not significantly improved, but the manufacturing cost increases excessively, which is not preferable.

The above glucosamine is contained in an amount of 3 to 5 parts by weight, and plays a role in providing a joint health improvement effect to the nutritional composition for improving joint health in companion dogs manufactured through the present invention. To explain in more detail, glucosamine is a natural substance found in the body, and exists as a structural unit in the sugar chains of various complex carbohydrates in the body. Representative examples include proteoglycans including mucopolysaccharides such as chondroitin sulfate or hyaluronic acid, and are widely distributed in general tissues, skin tissues, cartilage, and synovial fluid.

These glucosamines have a high moisturizing effect, maintain cell function and shape, and play important roles in cell surface functions such as lubrication, cell adhesion, proliferation, and differentiation, so they play a role in improving the joint health of companion dogs.

If the content of the above glucosamine is less than 3 parts by weight, the effect of improving joint health is minimal, and if the content of the above glucosamine exceeds 5 parts by weight, the effect is not significantly improved, while the manufacturing cost of the nutritional composition excessively increases.

The above propolis is contained in an amount of 0.5 to 1 part by weight, and it is preferable to apply it in powder form, and it plays a role in improving arthritis in companion dogs. To explain in more detail, propylose is a substance made by bees by mixing their saliva and enzymes with resin-like substances extracted from various plants for their survival and reproduction, and contains a large amount of organic matter and minerals (inorganic salts). Minerals, vitamins, amino acids, fats, organic acids, and flavonoids play an important role in cell metabolism, and overall, it exhibits anti-inflammation, antioxidant, and antibacterial effects.

If the content of the above propolis powder is less than 0.5 parts by weight, the above effect is minimal, and if the content of the above propolis powder exceeds 1 part by weight, the above effect is not significantly improved, while the manufacturing cost increases excessively.

The above zinc oxide is contained in an amount of 0.5 to 1 part by weight, and is a light white powder made of a compound of oxygen and zinc, also called zincite or zinc white. It exists in nature as red zinc stone and is manufactured through combustion and heating, etc., and plays a role in providing joint health improvement and immunity enhancement effects to the nutritional composition for improving joint health in dogs manufactured through the present invention.

The above vitamin _D3 is contained in 0.01 to 0.1 parts by weight, and helps the normal absorption of calcium, thereby promoting the proper formation of the dog's bones and strengthening the joints.

These days, since companion dogs spend most of their time indoors, their exposure to sunlight is limited, and the rate at which vitamin _D3 is synthesized in their bodies is low. Therefore, consuming vitamin _D3 has the effect of improving bone density in companion dogs.

The above ornithine hydrochloride is contained in an amount of 0.1 to 0.5 parts by weight, and not only acts as a flavor enhancer, but also secretes growth hormones to promote muscle synthesis and improve basal metabolism, thereby improving joint health and obesity in companion dogs and improving liver disorders. It is preferable to use one in the form of L-ornithine or L-aspartate.

The above safflower seed mixture contains 3 to 5 parts by weight, and the platinum component among the metal ions contained in the safflower seed induces an electrical action, thereby promoting the proliferation and division of osteoblast-like cells when fractured.

It activates calcium and promotes bone regeneration, and the copper contained in safflower seeds helps maintain joint health by promoting bone formation and regeneration in dogs through the action of linking calcium with various bone cells.

At this time, it is preferable that the safflower seed mixture is composed of 100 parts by weight of safflower seeds, 30 to 50 parts by weight of seaweed, and 10 to 30 parts by weight of eggshell.

The above seaweed contains a large amount of fucoidan and omega-3 fatty acids. The fucoidan improves inflammatory diseases including arthritis, and the omega-3 fatty acids reduce the degree of inflammation that causes arthritis, thereby improving the joint health of companion dogs.

In addition, the eggshell is a hard membrane located at the outermost part of the egg and contains a large amount of glycosaminoglycans, and it has been investigated to improve the serum CTX-II (C-telopeptide fragments of type II collagen) level, which determines the status of cartilage turnover in arthritis. Since the improvement in the CTX-II level suggests a significant cartilage protective effect, it can be said that the eggshell has a cartilage protective effect. Furthermore, the eggshell is rich in calcium and is used as the main ingredient in calcium supplements. Therefore, the eggshell shows the effect of maintaining the joint health of companion dogs.

If the content of the safflower seed mixture comprising the above ingredients is less than 3 parts by weight, the above effect is minimal, and if the content of the safflower seed mixture exceeds 5 parts by weight, the above effect is not significantly improved, and the palatability of the nutritional composition for improving joint health in companion dogs may be excessively reduced, which is not preferable.

The above herbal medicine for improving joints contains 1 to 3 parts by weight, and is preferably composed of at least one selected from the group consisting of Phellodendron amurense, Usul, Maga tree, and Heutgae. It is more preferable that the herbal medicine for improving joints consists of Phellodendron amurense, Usul, Maga tree, and Heutgae in a weight ratio of 1:1:1:1. The herbal medicine for improving joints composed of the above ingredients exhibits the effect of improving the joint health of companion dogs.

The above-mentioned Hwangchil improves diseases such as osteoporosis and arthritis by activating bone cells and promoting regeneration, and has the effect of promoting bone skeleton and growth and development in young companion dogs. In addition, the above-mentioned Usul has the effect of improving arthritis through excellent anti-inflammatory action, thereby improving the joint health of companion dogs. In addition, the above-mentioned Ma-ga-mok is effective for joint pain caused by degenerative arthritis or rheumatoid arthritis, and the above-mentioned Heot-gae has an excellent anti-inflammatory effect and has the effect of improving arthritis in companion dogs.

If the content of the above herbal medicine for improving joints is less than 1 part by weight, the above effect is minimal, and if the content of the above herbal medicine for improving joints exceeds 3 parts by weight, the above effect is not significantly improved, but the palatability of the nutritional composition for improving joint health in companion dogs is significantly reduced, which is not preferable.

The above natural preservative is contained in an amount of 0.01 to 0.1 parts by weight, and is preferably composed of one selected from the group consisting of green tea powder, mustard powder, rosemary powder, and sage powder, and is more preferably composed of green tea powder, mustard powder, rosemary powder, and sage powder mixed in a weight ratio of 1:1:1:1.

As described above, the natural preservative composed of the ingredients exhibits strong antioxidant, antibacterial and preservative properties, and thus not only provides an antioxidant effect to the nutritional composition manufactured through the present invention, but also plays a role in significantly improving the preservability by inhibiting deterioration or bacterial growth of the nutritional composition.

If the content of the above natural preservative is less than 0.01 part by weight, the above effect is minimal, and if the content of the above natural preservative exceeds 0.1 part by weight, the above effect is not significantly improved, but the palatability of the nutritional composition is lowered, which is not preferable.

The above-mentioned indigestible maltodextrin is contained in an amount of 10 to 15 parts by weight and has a role in providing a blood sugar level suppressing effect to the nutritional composition for improving joint health in companion dogs manufactured through the present invention.

Since the nutritional composition for improving joint health in companion dogs manufactured through the present invention has a high sugar content, even if it uses sugar components such as anhydrous crystalline glucose, fructooligosaccharide, isomaltooligosaccharide, galactooligosaccharide, maltooligosaccharide, xytooligosaccharide, and gentiooligosaccharide, which have relatively low absorption rates in the body, the blood sugar level in the body of a companion dog consuming the nutritional composition increases. However, if a blood sugar increase suppressant composed of indigestible maltodextrin is mixed as described above, the increase in blood sugar level in the body of a companion dog can be suppressed.

In addition, the above-mentioned indigestible maltodextrin is a water-soluble dietary fiber that, in addition to the effect of suppressing blood sugar increase, has the effect of increasing intestinal beneficial bacteria and lowering blood lipids, thereby playing a role in promoting the health of companion dogs.

If the content of the above-mentioned resistant maltodextrin is less than 10 parts by weight, the above-mentioned effect is minimal, and if the content of the above-mentioned resistant maltodextrin exceeds 15 parts by weight, the above-mentioned effect is not significantly improved, but the palatability of the nutritional composition may be excessively reduced, which is not preferable.

It contains 15 to 20 parts by weight of crystalline cellulose, and not only supplies dietary fiber, etc. to the nutritional composition manufactured through the invention, but also exhibits an anti-caking effect, thereby enabling the nutritional composition for improving joint health of companion dogs manufactured through the invention to maintain a powder form without hardening for a long period of time, thereby improving the preservation property.

If the content of the above-mentioned crystalline cellulose is less than 15 parts by weight, the nutritional composition may easily clump together even with a small amount of moisture, and if the content of the above-mentioned crystalline cellulose exceeds 20 parts by weight, the anti-caking effect of the nutritional composition is not significantly improved, but the palatability is excessively reduced, which is not preferable.

Hereinafter, a method for manufacturing a nutritional composition for improving joint health in dogs containing a Boswellia extract according to the present invention and the properties of a nutritional composition manufactured by the method will be described with reference to examples.

In addition, the antibacterial activity of the nutritional compositions for improving joint health in dogs manufactured through Examples 1 to 6 and Comparative Examples 1 to 6 was measured and shown in Table 3 below.

{However, for antibacterial activity, 10±0.1 g of samples of the nutritional compositions manufactured through Examples 1 to 6 and Comparative Examples 1 to 6 were prepared according to ASTM E2149-10, and 50±0.5 ml of the running dilution of the bacterial inoculum was added to each flask. After placing a sample of the manufactured nutritional composition in each flask, each flask was placed on a wrist-action shaker and shaken at maximum speed for 60±5 minutes, and the diluted solution was dispensed onto a flat plate and cultured in an incubator at 35±2℃ for 24 hours, and the number of colonies in the cultured Pedri dishes was checked under a microscope.

Additionally, the antibacterial activity was calculated using the following formula.

Antibacterial power (%) = (B-A)/B × 100

A: Bacterial count after contact time between sample and bacterial dilution solution

B: Bacterial count in the untreated control group

* Negative control group 100%, positive control group 5.4%}

<Table 3>

As shown in Table 3 above, the nutritional compositions manufactured through Examples 1 to 6 of the present invention exhibited excellent antibacterial performance, but it can be seen that the nutritional composition that did not contain a natural preservative, such as Comparative Example 3, had low antibacterial performance.

Therefore, the nutritional composition for improving joint health in dogs containing a Boswellia extract according to the present invention contains an abundance of nutrients beneficial to joints, thereby improving joint health in dogs and providing a nutritional composition exhibiting excellent palatability and storability.
