Description

Method for producing a pet food additive composition containing frog meal as a meat substitute and a pet food additive produced thereby

[0001] The present invention relates to a method for producing a pet food additive composition containing duckweed as a meat substitute and a pet food additive produced thereby, and more particularly, to a pet food additive having a low-allergy functionality by containing duckweed with a high protein content, thereby replacing meat-based food additives that cause allergies in pets.

[0002] Depending on the person, eating certain foods can cause symptoms such as hives, erythema, rashes, itching, abdominal pain, diarrhea, fever, vomiting, and chills within a short period of time. This is called a food allergy. The cause of these symptoms includes allergies due to immunological reactions, that is, allergies due to antigen-antibody reactions. The antigens contained in the causative food are called allergens, and are usually proteins.

[0003] Animals, like humans, can also experience food allergies. Regardless of the season, they can experience itching sensations following the ingestion of one or more ingredients in their feed or food. While the pathogenesis is not fully understood, immediate or delayed reactions to specific ingredients can occur, resulting in itching, vomiting, diarrhea, and, in rare cases, convulsions. Therefore, these food allergies can significantly reduce a pet's quality of life.

[0004] Food allergies account for 5% of all skin diseases, and in dogs and cats, 10-15% of allergic skin diseases are hypersensitivity reactions to food. It is the third most common itchy skin disease in dogs, and there is no species-specific or breed-specific or age-specific prevalent disease.

[0005] Meanwhile, companion animals are becoming increasingly diverse, encompassing not only dogs and cats but also parrots, hedgehogs, rabbits, and hamsters. Dogs make up the largest proportion of companion animals, and they are particularly prone to allergies to foods like milk and meat. However, dog food and treats typically contain meats like beef, pork, chicken, and duck, leaving many dogs vulnerable to food-related allergies.

[0006] In relation to this, according to Korean Patent No. 10-2498755 (Feed Raw Material Using Black Fly Larvae), a feed raw material containing dried black fly larvae has been developed to replace the above-mentioned allergy-inducing products. However, black fly larvae have a high fat content, so they are transformed into a powder or dough-like form during the process of grinding them to a specific particle size. Therefore, there is a problem in the process of manufacturing them into a powder form, such as by removing the fat or by processing them through additional processes after grinding.

[0007] Accordingly, the inventors of the present invention have completed the present invention by manufacturing a feed additive including a plant-based raw material capable of promoting the health of companion animals, containing frog meal as a high-protein plant-based raw material that does not require an additional process for manufacturing in powder form and does not cause dietary allergies in companion animals.

[0008] Accordingly, the present invention provides a method for manufacturing a granular pet food additive composition containing frog meal for meat substitute, as a technical solution.

[0009] In addition, the present invention provides a granular pet food additive composition for meat substitute containing frog meal manufactured by the above method as another technical solution.

[0010] In addition, the present invention provides a pet food additive for meat substitute containing frog meal, which comprises the above composition, as another technical problem.

[0011] In order to solve the above technical problem, the present invention,

[0012] A step of preparing beet powder, sweet potato powder, pumpkin powder, and carrot powder and mixing them to make a vegetable powder;

[0013] A step of producing frog meal powder by crushing dried frog meal;

[0014] A step of mixing the above plant powder and frog meal powder and then drying with hot air to produce a mixed powder; and

[0015] A step of granulating the above mixed powder to produce a granular powder;

[0016] A method for manufacturing a granular pet food additive composition containing frog meal for meat substitute is provided.

[0017] In the present invention, the granular powder is characterized by having a diameter of 100 to 200 mesh.

[0018] In the present invention, the composition is characterized by comprising 100 parts by weight of plant powder and 10 to 40 parts by weight of frog meal powder.

[0019] In the present invention, the step of manufacturing the mixed powder comprises:

[0020] After mixing the above vegetable powder and frog meal powder,

[0021] The method is characterized by further mixing one or more palatable powders selected from apple powder, soybean powder, blueberry powder, broccoli powder, pumpkin powder, cabbage powder, celery powder, corn powder, cranberry powder, kale powder, leek powder, lemon powder, mushroom powder, onion powder, orange powder, potato powder, spinach powder, tomato powder, and zucchini powder, and drying the mixture with hot air to produce a mixed powder.

[0022] In addition, in order to solve the above other technical problems, the present invention,

[0023] A granular pet food additive composition for meat substitute containing frog meal, characterized in that it is manufactured by the manufacturing method of the present invention, is provided.

[0024] In addition, in order to solve the above-mentioned other technical problem, the present invention,

[0025] A meat substitute pet food additive containing frog meal, characterized in that it comprises the composition of the present invention and is manufactured in a capsule, pellet or liquid form, is provided.

[0026] According to the present invention, by including duckweed as a plant-based protein source, it is possible to provide pets with protein that does not cause allergic reactions in the form of feed or snacks. Furthermore, by including beet powder, sweet potato powder, pumpkin powder, and carrot powder as plant-based powders with antioxidant properties, the present invention can promote the health of pets and, in particular, provide anti-aging benefits to elderly pets.

[0027] Additionally, it contains a lot of fiber as well as protein, which can help promote digestion and improve intestinal health in pets.

[0028] Figure 1 is a flow chart showing a method for manufacturing a granular pet food additive composition for meat substitute containing frog meal according to the present invention.

[0029] Figure 2 is an image of a step of mixing vegetable powder and frog meal powder according to one embodiment of the present invention.

[0030] Figure 3 shows various types of food additives according to one embodiment of the present invention.

[0031] The present invention is described in detail below.

[0032] Throughout the specification, whenever a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0033]

[0034] According to the present invention, a method for manufacturing a granular pet food additive for meat replacement containing duckweed as a plant-based protein source, which can replace animal-based feed that causes allergies, can be provided. Accordingly, the present invention can manufacture a vegan food additive that does not cause allergies as an alternative protein source to salmon, chicken, pork, beef, etc., which are commonly used in pet feed.

[0035] Figure 1 is a flow chart showing a method for manufacturing a granular pet food additive composition for meat substitute containing frog meal according to the present invention.

[0036] With reference to this, in one aspect, the present invention relates to a method for producing a granular pet food additive composition for meat substitute containing duckweed, which comprises the steps of preparing beet powder, sweet potato powder, pumpkin powder, and carrot powder and then mixing them to produce a vegetable powder; the step of grinding dried duckweed whole plants to produce duckweed powder; the step of mixing the vegetable powder and duckweed powder and then drying them with hot air to produce a mixed powder; and the step of granulating the mixed powder to produce a granular powder.

[0037] The steps are explained below.

[0038] First, the plant-based powder manufacturing step involves manufacturing powder using plant-based ingredients with antioxidant properties and high palatability. Specifically, beet powder, sweet potato powder, pumpkin powder, and carrot powder are prepared and then mixed to produce the plant-based powder.

[0039] The above beets, sweet potatoes, pumpkins, and carrots are antioxidant foods containing phytochemicals and are rich in dietary fiber, which helps improve intestinal function and can improve the skin and coat of pets.

[0040] Specifically, the red pigment in beets is a component called betaine, which inhibits cell damage, has antioxidant properties, and has an anti-inflammatory effect. It is also known as a diet food and health food because it is low in fat, cholesterol, and calories.

[0041] Additionally, pumpkin contains a large amount of the powerful antioxidant beta-carotene, which inhibits cell oxidation and removes free radicals that promote aging. This antioxidant action helps prevent cell aging. In addition to vitamin A, pumpkin is rich in beta-carotene, which is converted to vitamin A upon absorption, thus protecting vision. Furthermore, its antioxidant properties, including beta-carotene and vitamins A and C, help prevent skin aging.

[0042] In addition, carrots are rich in beta-carotene as well as lutein and lycopene, which are nutrients for eye health, so they provide antioxidant functionality and are helpful for eye health.

[0043] Sweet potatoes also contain anthocyanins, polyphenols, and beta-carotene, which have antioxidant properties and can enhance palatability. It is recommended to use purple sweet potatoes, which are high in polyphenols.

[0044] At this time, the vegetable powder can be manufactured by mixing beet, sweet potato, pumpkin, and carrot powders in a ratio of 1~2: 1~2: 1~2: 1~2 to increase palatability as a feed additive. More preferably, when mixed in a ratio of 1:1:1:1, the taste of beet and carrot can be neutralized by the sweet taste of sweet potato and pumpkin, thereby increasing palatability.

[0045] The next step is to manufacture frog rice powder. Dried frog rice whole plant is ground to manufacture frog rice powder.

[0046] Duckweed, also known as "Lemna," is a plant-based protein source with a higher protein content than soybeans, a representative high-protein plant. Lemna is an aquatic plant. Its most notable characteristic is its ability to produce enormous yields with minimal water and time. It grows extremely quickly, doubling in just 24-36 hours. It also self-renews continuously, allowing for daily harvests. Like seaweed, it can be easily and effectively cultivated in open farms (raceways) or water tanks. Compared to soybeans, it requires only one-tenth the amount of water per kilogram, making it economical to grow. Furthermore, the protein in duckweed is similar to that of meat, making it an effective source of protein for meat substitutes. It contains more essential amino acids and BCAA (Branched Chain Amino Acids) than soybeans, which are comparable to whey protein. Furthermore, when comparing just the protein content, soybeans have a protein content of 36%, while duckweed has a higher protein content of 45%. Furthermore, duckweed is rich in B vitamins, flavonoids, chlorophyll, glycoproteins, folic acid, iron, calcium, and potassium, which can help improve your pet's nutritional intake and health.

[0047] Therefore, the feed additive of the present invention not only improves the ease of supplying raw materials in the manufacturing process by including frog meal, but also increases the protein content and nutritional content while increasing the palatability as a meat substitute protein.

[0048] The next step in manufacturing the mixed powder is to mix the above vegetable powder and frog meal powder and then dry them with hot air.

[0049] FIG. 2 is a photograph showing a step of mixing vegetable powder and duckweed powder according to one embodiment of the present invention. Referring to this, duckweed powder is added to vegetable powder composed of beet, sweet potato, pumpkin, and carrot powder, mixed by stirring, and then hot air drying is performed to produce a mixed powder. At this time, it is preferable that the hot air drying is performed so that the moisture content is 5% or less of the total. In a preferred embodiment of the present invention, it was produced by hot air drying at 80°C for 80 minutes.

[0050] At this time, the above mixing should include 100 parts by weight of vegetable powder and 10 to 40 parts by weight of frog's meal powder. If the frog's meal powder is mixed in amounts below the above range, the protein supply by the frog's meal powder will be insufficient, and if the frog's meal powder is mixed in amounts exceeding the above range, the palatability will be poor, which is not desirable.

[0051] More preferably, in the step of manufacturing the mixed powder, a palatability powder may be further included to improve the pet's intake by mixing with the vegetable powder and frog powder, thereby manufacturing the mixed powder. That is, after mixing the vegetable powder and frog meal powder, one or more palatability powders selected from apple powder, soybean powder, blueberry powder, broccoli powder, pumpkin powder, cabbage powder, celery powder, corn powder, cranberry powder, kale powder, leek powder, lemon powder, mushroom powder, onion powder, orange powder, potato powder, spinach powder, tomato powder, and zucchini powder may be further mixed, and the mixture may be dried with hot air to manufacture the mixed powder.

[0052] At this time, it is preferable that the palatable powder is further included in a ratio of 10 to 40 parts by weight per 100 parts by weight of the vegetable powder. More preferably, beet powder, sweet potato powder, pumpkin powder, carrot powder, frog meal powder, and palatable powder can all be mixed in the same weight ratio.

[0053] The final step in manufacturing granular powder is to granulate the above-described mixed powder. Granulation is a phenomenon in which particles become agglomerated, thereby increasing the size of the powdered ingredients, thereby obtaining powder flowability and the manufacturing process properties required for compression. Granulation can be performed by dry granulation or wet granulation, and preferably, the granular powder can be manufactured by spray granulation using the wet granulation method. Granulating the powder in this step not only improves the ease of ingestion itself, but also increases the ease of mixing when manufacturing food additives in capsule, capsule, pellet, or liquid forms.

[0054] At this time, it is preferable that the granular powder has a diameter of 100 to 200 mesh. If the diameter of the powder is less than the above range, the powder may be too fine, requiring more time for the granulation process, and if the diameter exceeds the above range, granulation may be difficult.

[0055]

[0056] Accordingly, in another aspect, the present invention relates to a granular pet food additive composition for meat substitute containing frog meal manufactured by the above-described method.

[0057] As described above, it has antioxidant properties including beets, sweet potatoes, pumpkins, and carrots, and as a source of protein for meat substitutes, it contains duckweed, and as a plant-based raw material, it is rich in dietary fiber, which can improve intestinal function and hair.

[0058] Preferably, the food additive composition may further include probiotics. This is to aid digestion in pets, who have a short digestive tract and therefore have difficulty digesting solid foods like meat. It also promotes digestion, promotes the growth of beneficial intestinal bacteria, and aids bowel movements. Improved digestive function and improved inner beauty due to beneficial intestinal bacteria can also lead to improvements in skin and coat quality.

[0059] In another aspect, the present invention relates to a food additive manufactured in a capsule form, a capsule form, a pellet form or a liquid form, including the granular food additive composition.

[0060] Figure 3 illustrates various forms of food additive formulations according to one embodiment of the present invention. Referring to Figure 3, the formulations can be manufactured into capsules (a), pellets (b), and stick-shaped purees (c) manufactured by the above manufacturing method, but are not limited thereto, and any form capable of containing and fixing the formulation can be used.

[0061] Specifically, the above food additive can be manufactured in the form of a capsule by packaging the above-described granular powder in powder form.

[0062] Alternatively, the solid may be produced by further performing the steps of adding agar and water to granular powder, mixing well at 100 to 150°C for 10 to 60 minutes, and gelatinizing; cooling the gelatinized raw material at a temperature of up to 10°C to produce a solid; and drying the solid at 50 to 150°C for 5 to 10 hours to dry the solid.

[0063] At this time, in the solid material manufacturing step, the raw material can be cooled in a mold of a certain size to manufacture pellets.

[0064] Additionally, the above solid material can be diluted and placed in a stick-shaped container to produce a stick-shaped puree.

[0065]

[0066] Hereinafter, the present invention will be described in more detail with reference to preferred embodiments. However, these embodiments are intended to illustrate the present invention more specifically, and it will be apparent to those skilled in the art that the scope of the present invention is not limited thereby.

[0067]

[0068] <Example 1>: Manufacturing of pet feed additives using frog meal

[0069] Beet, purple sweet potato, sweet pumpkin, and carrot powders were prepared and mixed. Dried whole plants of Spirodela polyrhiza were purchased and powdered using a grinder. Equal amounts of the above beet, purple sweet potato, sweet pumpkin, carrot, and duckweed powders were mixed and dried with hot air at 80°C for 80 minutes. The powders were ground to a size of 100-150 mesh, and granular powder (processing material) was prepared using the spray granulator. The manufacturing facility was set to a temperature of less than 10°C and a humidity of less than 30%.

[0070]

[0071] Manufacturing Example 1-1: Capsule Manufacturing

[0072] A pet food additive containing frog meal was manufactured by filling 1000 mg of the processed raw material manufactured in Example 1 into 1000 mg of a capsule using a packaging machine.

[0073]

[0074] Manufacturing Example 1-2: Pellet Manufacturing

[0075] 20 g of agar and 500 g of water were added to 1000 g of the processed raw material manufactured in Example 1, stirred, and mixed well at 100-120°C before gelatinization.

[0076]

[0077] Manufacturing Example 1-3: Manufacturing stick-type puree

[0078] 20 g of agar and 500 g of water were added to 1000 g of the processing source manufactured in Example 1, stirred, and mixed well at 100-120°C, and then gelatinized (cooked like thick paste) for 30 minutes. The mixture was poured into a stick-type puree mold and refrigerated in a refrigerator set to below 10°C to produce a solid. The solid was dried at 80°C for 7 hours to produce a stick-type puree.

[0079]

[0080] <Comparative Example 1> Manufacturing of food additives that do not contain frog meal

[0081] Beet, purple sweet potato, pumpkin, and carrot powders were mixed and hot-air dried at 80°C for 80 minutes. The dried mixed powders were ground to a size of 100–150 mesh and granulated to produce granular powder (processing material). The manufacturing facility temperature was set to below 10°C and humidity below 30%.

[0082] 2 g of agar and 100 g of water were added to 1000 g of the processed raw material manufactured in Example 1, stirred, and mixed well at 100-120°C before gelatinization. The mixture was poured into a 2X2 cm grid frame and refrigerated in a refrigerator set to below 10°C to produce a solid. The solid was dried at 80°C for 7 hours to produce pellets.

[0083]

[0084] <Example 1> Symbol evaluation

[0085] A preference evaluation was conducted on the food additives including the duckweed powder according to the present invention of Manufacturing Examples 1-1, 1-2, and 1-3 and the food additive not containing the duckweed powder of Comparative Example 1. The preference evaluation was conducted on 50 healthy pet dogs aged 2 to 14 years. Each dog was fed [Manufacturing Examples 1-1] to [Manufacturing Examples 1-3] and [Comparative Example 1], and the owner of each dog was asked to indirectly evaluate the preference by observing the eating behavior of the dog. The preference was evaluated using a 9-point scoring system (9: very good, 7: good, 5: average, 3: bad, 1: very bad), and the results are shown in [Table 1].

[0086] Manufacturing example 1-17.9 Manufacturing example 1-27.7 Manufacturing example 1-37.6 Comparative example 15.2

[0087] As confirmed in Table 1 above, it was confirmed that Manufacturing Examples 1-1 to 1-3 as pet food additives using frog meal according to the present invention were evaluated as significantly higher than Comparative Example 1. In particular, in the case of Manufacturing Example 1-1, the capsule was directly put into the dog's mouth for ingestion, or the powder was sprinkled on top of dry or wet food for ingestion. It was confirmed that the pet's preference was not reduced even in the powder form. In the case of Manufacturing Examples 1-2 and 1-3, although they were manufactured in the form of pellets and stick-type purees so that the dog could directly ingest them, the preference was evaluated as being almost as high as that of Manufacturing Example 1-1, and it was confirmed that the dog ate them without any aversion.

[0088]

[0089] <Example 2> Sensory Evaluation

[0090] The food additives including the frog meal powder according to the present invention of Manufacturing Examples 1-1, 1-2, and 1-3 and the food additive not including the frog meal powder of Comparative Example 1 were evaluated for improvement in coat quality and stool condition. The evaluation was conducted by feeding the food additives of Manufacturing Examples 1-1 to 1-3 and Comparative Example 1 together with feed for 60 days to 50 healthy pet dogs aged 2 to 14 years. The evaluation criteria were described as ◎: very good, ○: good, ×: poor, and the results are shown in [Table 2].

[0091] Classification Change Pattern Manufacturing Example 1-1 Manufacturing Example 1-2 Manufacturing Example 1-3 Comparative Example 1 Gloss of hair ◎◎◎× Good at looking at the change ◎○◎○

[0092] As shown in Table 2 above, when duckweed powder was included, it was confirmed that the pet dog's fur became shiny and it had good defecation. The standard for good defecation means that there is no loose or diarrhea, and it means brown feces as is commonly said, and the gloss of the fur is confirmed by the degree of gloss of the fur that is visible to the naked eye as a change in the fur quality. On the other hand, in the case of Comparative Example 1 that did not include duckweed powder, there was no significant change in defecation, but the fur was found to have poor gloss. This appears to be a change due to the feed containing meat, and is confirmed to be a result of allergy or non-intake of nutrients.

[0093]

[0094] <Test Example 3> Formulation Stability Evaluation

[0095] The stability evaluation of the food additives manufactured in Manufacturing Examples 1-1 to 1-3 was conducted. The stability evaluation was conducted by visually examining the food additives containing the manufactured frogbit at low temperatures (2°C) and above room temperature (30°C) for 1 week, 1 month, 3 months, and 6 months to determine whether separation of components or spoilage occurred. The results are shown in [Table 3] below. The evaluation criteria were as follows: ◎: Very good, ○: Good, ×: Poor.

[0096] Manufacturing Example 1-1 Manufacturing Example 1-2 Manufacturing Example 1-32℃1 week◎◎◎1 month◎◎◎3 months◎◎◎6 months◎○○40℃1 week◎◎◎1 month◎◎◎3 months◎○○5 months◎○○

[0097] As shown in Table 3 above, the food additive containing the frog meal according to the present invention can be stored for a long time at both low temperatures (2°C) and temperatures higher than room temperature (30°C), and exhibited stability of the formulation. All of Manufacturing Examples 1-1 to 1-3 can be distributed in a sealed form, and it was confirmed that they are excellent for long-term storage because they do not spoil or become moldy. From the above results, it was confirmed that the present invention is a food additive that is highly palatable to companion animals, and that it improves the coat and stool of companion animals, and it was confirmed that it can effectively increase beneficial intestinal bacteria and improve bowel movements without causing allergies.
