[0003]

However, the above-mentioned conventional animal feed for pets, which mainly consists of minced meat of fish, bran, etc., has a problem that it lacks wild taste. Further, since the feed is soft, there is a problem that the gums and lower jaws of small dogs and cats are weakly developed. Furthermore, since the feed is mainly protein such as bran, there is a problem that the calcium content is insufficient and must be supplemented separately.
Further, since the feed is paste-like and soft, there is a problem that tartar is likely to accumulate. In addition, the above-described conventional method for producing animal feed for pets has a problem in that the number of manufacturing steps is wide, and each manufacturing step is complicated, resulting in lack of workability and productivity. In addition, there is a problem in that the bone is liable to be boiled just by boiling it and the stomach and intestines are easily damaged.
Furthermore, since a large amount of lipid is contained in the waste water discharged during the manufacturing process and the BOD and COD of the waste water are high, there is a problem that a great burden is required for treating the waste water.

The present invention solves the above-mentioned conventional problems and is good for the health of pet animals, and can soften even large bones without damaging the internal organs of pets, satisfying the taste of pet animals and stressing them. In addition to eliminating the above, it is a low-fat and excellent nutrient that enhances appetite by reinforcing calcium content, prevents the attachment of tartar, and provides a pet animal feed with high product yield that is also excellent in preservability, In addition, it provides a method for producing animal feed for pets that has good workability, excellent nutritional value such as calcium, low fat, high safety, high productivity, easy wastewater treatment, low cost and high mass productivity. The purpose is to do.

Here, as livestock, cattle, horses, pigs, sheep,
Domestic animals such as rabbits and nutrias are used.
Any fish can be used as long as it can be eaten by humans, and preferably large fish bones are used. Chickens are not preferred because bones can hurt the internal organs. As the bone portion, a bone having a large morphology such as a femur, a humerus, or a rib is preferably used. Fresh bone immediately after dismantling is preferably used as the bone. In addition, you may use what frozen immediately after disassembly. Meat does not have to be attached to the bone, but it is preferable that it is attached to some extent because it can stimulate the appetite of pets. The bone of livestock or fish is preferably 75% to 10% of raw raw bone.
%, Preferably 60% to 20%. As the bone marrow and other lipids exceed 60% of the raw bone, the bone marrow tends to exude when the bone is cut, and the surface tends to become sticky due to fat and the like. It is not preferable as it may cause diarrhea in dogs. In addition, when degreasing to less than 20%, it is not preferable because the fat content at the time of production imposes a burden on wastewater treatment and tends to lower the nutritional value and further reduce the palatability.

No seasoning may be added to the retort treated bone. When the seasoning is not added, it has a wild taste and can be used as a feed for healthy dogs. Also,
Appetite can be enhanced by adding seasonings to the bone. The seasoning may be only one of miso, soy sauce, and salt. These aromas and saltiness can enhance appetite. The addition ratio of salt and soy sauce is 5 wt% to 0.001%, preferably 3 wt% to the weight of the whole bone.
0.01 wt% is used. As salt exceeds 3 wt%, bones tend to be seasoned and dogs tend not to like it.
It is not preferable because it also causes health problems. The amount of salt added is appropriately selected depending on the type and size, such as small and large puppies and adult dogs. Further, as the amount becomes less than 0.01% by weight, there is a tendency that a dog or the like having no taste and weak body does not appetite. Addition ratio of miso is 0.1wt% of miso to the whole bone
.About.20 wt%, preferably 1 wt% to 10 wt%. Puppies and adult dogs or small and large dogs are appropriately selected depending on their type and size. When a liquid seasoning is used, the seasoning is added by dipping with a brush or dripping, or by putting the seasoning and bone in a pan and entangled. Also,
It is also possible to facilitate weighing by injecting it into the retort pouch using a dropper. When the seasoning is a paste, it is applied by a method such as brush coating, putty coating or dipping and wiping. Alternatively, the seasoning may be directly added to the retort pouch together with the bone without being attached to the bone. It can be mixed and integrated with bone marrow or the like that is eluted from bone during retort treatment.

[0008] Miso, soy sauce, and salt used as main ingredients of seasonings vary depending on the type of pet, but they are bonito dashi, kelp dashi, shiitake dashi, sugar, sesame, mirin-flavored seasoning, amino acids. Seasonings, sauces, vitamins, etc. are used. As other auxiliary materials, one or a mixture of two or more of bulking agents such as wheat flour, bran, meat flour and soybean protein is used. In addition, calories can be adjusted by adding lard, butter, margarine and the like. Other auxiliary materials such as vegetables (excluding onions), herbs, herbs, seaweeds, grain soups, etc. may be added to improve the flavor. The blending ratio of the auxiliary material is 0.01 wt part to 200 wt with respect to 100 wt part of the bone.
Parts, preferably 1 to 50 parts by weight. By blending in this range, it is possible to impart flavor and enhance appetite without impairing the nutritional value of bone.

The washing process is particularly effective when dirt, soil, blood, etc. are attached to the bone. Moreover, the appearance of the product can be improved by removing the blood from the raw bone. As for the treatment method, preservability and quality can be improved by immersing in water, sodium hypochlorite, dilute aqueous solution of chlorine dioxide or the like for washing for 5 to 30 minutes to remove blood. Frozen bone may be washed with water while thawing and removing blood in a solution of dilute sodium hypochlorite, chlorine dioxide, or the like.

The heating of the steaming treatment is carried out at a heating temperature of 100 to 200 ° C, preferably 105 to 150 ° C. 10
When the temperature is lower than 5 ° C, it takes time to cook, and the quality tends to deteriorate, which is not preferable. On the other hand, as the temperature becomes higher than 150 ° C., the surface of the bone is deteriorated and the meat around the bone tends to be peeled off, which is not preferable. The treatment time depends on the steaming temperature, but is 5 to 120 minutes, preferably 10 to 8 minutes.
It is performed in the range of 0 minutes. When the time is less than 10 minutes, unheated parts are generated in the product, which causes putrefaction. On the other hand, when the time is more than 80 minutes, meat is peeled from the bone, and the extract content tends to be lost to lower the nutritional value, which is not preferable. These processing conditions are appropriately selected depending on the size of the bone and the retort processing in the subsequent process. In addition, the pressure should be 0.1 when heating.
When 10 to 10 kg / cm ² , preferably 0.3 to 3 kg / cm ² , heat easily passes to the inside, the treatment time can be shortened, and the degreasing efficiency of bones of livestock or fish can be increased. In addition, the bone tissue can be altered so that the dog can easily bite the bone. When dirt, soil, blood, etc. are attached to the raw bone, the preservability and quality can be improved by performing a steaming treatment with hot water for 5 to 30 minutes for washing and sterilization in the previous step. Frozen bones may be washed with water while thawing and removing blood in a dilute sodium hypochlorite solution or the like.

It is preferable that the boiling step is performed 1.2 to 4 times longer than the steaming treatment. If the time is too short, degreasing will be insufficient, which is not preferable, and if the time is too long, the meat will peel off from the bone, which is not preferable.

The cooling treatment includes a vacuum drying method of evaporating water in a vacuum state after steaming or boiling and cooling by the latent heat of vaporization, or slow cooling after steaming or boiling, and then -5 ° C to 0 ° C.
A refrigerating method of cooling in a refrigerating room at ℃, a quick chiller capable of preventing the elution of fat, etc. are used. By performing the cooling treatment, large bones can be easily cut because the tissue is deteriorated by the heat and pressure treatment. Further, at this time, since oil and fat components such as fat are solidified by cooling, it is possible to prevent the bone marrow from flowing out. The length of the bone is adjusted by 0.5 cm to 15 cm, preferably 0.4 cm to 10 cm in a direction orthogonal to the length direction of the bone.
Preferably, it is formed into slices of cm. As it becomes less than 1 cm, the body tends to collapse and the appearance tends to be poor, but it may be 0.5 to 1 cm for puppies and small dogs. This is because it is easy to swallow. Moreover, as the size of the puppy becomes larger than 10 cm, it tends to be too large to eat, which is not preferable.

As the retort pouch, a pouch for a general retort pouch may be used, but a high retort pouch is preferably used. It is possible to reduce the occurrence of accidents such as pinholes during vacuum sealing and improve the product yield.

In the retort process, the heating temperature is 100 to 180.
℃, preferably 110 ℃ ~ 150 ℃, pressure 0.1 ~ 1
5kg / cm ^2, preferably in the 1.5~5kg / cm ² 2~80
High retort sterilization for 10 minutes to 10 minutes is preferably used. When heating or the like is performed once in the previous step, sterilization can be sufficiently performed in a short time as compared with the conventional case.

[0015]

With this configuration, the animal feed for pets and the method for producing the same of the present invention have the following actions. In other words, since it is a feed mainly consisting of bones, it stimulates the appetite of carnivorous animals such as dogs and cats, and when salt, especially miso or soy sauce, is added, salt and amino acids, etc. satisfy the palatability of pets and enhance their appetite. be able to. If the amount of salt, miso, or soy sauce is significantly reduced, or if it is not added, it does not cause adult diseases such as high blood pressure and can maintain health. Further, since no sugar is added, it is possible to prevent caries from forming on the teeth of pets such as dogs and cats. If you cut the bone into small slices, even small breeds, puppies, and kittens can swallow them to replenish their nutrition, and since they are rich in calcium, they can make them stronger. When using soy sauce, miso, or the like containing no preservative or the like, it is possible to obtain a pet animal feed excellent in health. By adjusting the treatment conditions such as treatment pressure and treatment time according to the type and size of the pet animal, the degree of softness can be controlled even with large bones such as the femur, and the bones flared up due to heat and pressure. Since there are no dogs or kittens, they can be eaten safely. Since the bone is moderately soft and the fat content is solidified by cooling, it can be easily processed according to the type and size of the pet.
3 when cooling by vacuum drying or vacuum cooling
Since it can be dehydrated and dried up to 15%, the water content can be lowered and the water activity can be increased, and the storability and the flowability can be markedly improved. Also, by cooling, the fat content such as bone marrow coagulates so that it can be cut cleanly without flowing out. Since 10% to 70% of the raw material can be defatted by steaming or boiling, it can be a healthy feed that is low in fat and does not cause diarrhea. Since bones and the like are put in the retort pouch and heated and pressurized at 100 ° C. or higher, it is possible to completely sterilize and improve the preservability.
In addition, the high retort treatment makes it difficult for proteins to discolor, and changes in the components can be reduced. When meat is attached to a part of the periphery of the bone, it is possible to produce a pet feed that is easy to eat and has excellent nutritional value. Since the degreasing rate is 10 to 70%, BOD and COD can be kept low, and the burden on wastewater treatment can be reduced. In addition, the exudation of fat such as bone marrow during the bone cutting process can be reduced, and the productivity can be improved.
Since the bone has an appropriate hardness, stress can be chewed to release stress, and the gums and lower jaw can be strengthened to remove plaque.

[0016]

EXAMPLE An animal feed for pets and a method for producing the same will be described below with reference to one example of the present invention. (Example 1) Prepare 200 pig femurs immediately after disassembly,
It was immersed in running water for washing in the blood removal washing step. Then, in a pressure cooker at a heating temperature of 100 to 120 ° C., 0.6 to 2
A pressure steaming treatment was performed by passing steam at a pressure of kg / cm ² for about 15 to 30 minutes to degrease fats such as bone marrow. When the degreasing rate was measured, the fat content such as bone marrow was 23.1 ±
It was defatted by 3%. Then, the pressure-steamed bone is rapidly cooled to room temperature or below in a refrigerating room, and then the length is 6 ± 1 cm.
Disconnected. The cooled bone was cut cleanly without solidification of the bone marrow and no outflow. Next, vacuum-pack each 5 cut bones in a retort pouch, put in a retort kettle, and heat at 100-130 ° C, 1.5-4 kg / cm ²
The heat and pressure treatment was performed for 20 to 60 minutes at the pressure of. The product was taken out from the retort kettle and cooled as it was in the retort pouch to obtain a product. Next, the composition of the components of the obtained product was analyzed. The results are shown in (Table 1).

[Table 1] As is clear from this (Table 1), the pet feed of this example was found to have a low crude fat content of 6 to 15%. In addition, the content of crude protein, phosphorus, and calcium was high, and it was highly evaluated by veterinarians. Since the bone was used while maintaining its shape, and the lipid content that had flowed out from the bone marrow during retort was adhered to the bone on the surface of the bone, it was excellent in wild taste and was appetizing. Furthermore, since the calorie was adjusted by adding lard, and bone marrow was used as it was, a veterinarian evaluated that it was excellent in nutrition. Next, 5 shepherd puppies each having a age of 1.5 months and 5 adult dogs were subjected to a diet test for 2 weeks.
The test was conducted at 5 months for puppies at 1 / day and for adult dogs at 2 / day. As a result, no diarrhea symptom was observed, and the dog was in good health and heavier than those of the dogs (Comparative Example) not fed the pet feed of this Example. From this, in the pet feed of the present example, since the bone is denatured and softened by the pressure steaming treatment at high temperature and high pressure, the internal organs and the like of pets such as small dogs and small cats are damaged. It was found to be a pet feed with excellent safety. still,
Similar to this example, the femurs of cattle, horses, and sheep immediately after disassembling were used for confirmation, and the same results as in this example were obtained.

(Example 2) 200 ribs of cattle that had been refrigerated (1 day) after dismantling were prepared, and in the blood removal washing step, blood was removed by immersing in the cold water containing 45 to 65 ppm of sodium hypochlorite. At the same time, cleaning was performed. Then, it was placed in a large pot and boiled for about 30 to 70 minutes to remove fats such as bone marrow. When the defatted rate was measured, fat such as bone marrow was defatted by 15% to 35% of the raw material, and crude fat was 5% to 10%.
Met. Then, this boiled bone was rapidly cooled to room temperature or below in a refrigerating room, and then cut into a length of 7 ± 1 cm. The cooled bone was cut cleanly without solidification of the bone marrow and no outflow. On the other hand, seasoning soy sauce prepared by adding a small amount of kelp soup, sesame, seasoning such as mirin-style seasoning, wheat bran, and starch to soy sauce is prepared, and 5 pieces of cut bones are added to a retort pouch, Inject 0.5 to 25 g of seasoned soy sauce with a dropper, vacuum-pack and put in a retort kettle for 100-
² at a heating temperature of 140 ° C and a pressure of 1.01 to 4 kg / cm 2.
Heat and pressure treatment was performed for 0 to 60 minutes. The product was taken out from the retort kettle and cooled as it was in the retort pouch to obtain a product. The animal feed for pets manufactured as described above is a pet animal feed with excellent safety that does not damage the internal organs of pets, etc., because the bone tissue is denatured and softened by the boiling treatment. I found out. Next, Shiba Inu 4
5 months old and 5 months old puppies and 5 adult dogs were allowed to feed for 2 weeks and a feeding test was conducted. The test is 4 months old and the puppies are 6
0 g / day, 90 months / day for 8-month puppies and 90 g / day for adult dogs. As a result, no diarrhea symptom was observed, and the dog was in good health and heavier than those of the dogs (Comparative Example) not fed the pet feed of this Example. Further, in the feed of this Example, the lipid content flowing out from the bone marrow at the time of retort was smeared and adhered to the bone, and soy sauce permeated well into the bone marrow, so that the preference of pets was better than that of the pet feed of Example 1. And was extremely appetizing. In addition, a veterinarian has obtained extremely high evaluation as a feed for pets. In addition, although it confirmed using the rib of the pig and the sheep refrigerated after disassembly (3 days) like this Example, the same result as this Example was obtained.

(Example 3) 200 frozen femur bones of pigs were prepared and immersed in cold water containing 45 to 65 ppm of sodium hypochlorite to bleed and thaw the blower while washing. Then 110-150 in the pressure cooker
Approximately 15 to ² at a heating temperature of ℃ and a pressure of 5.5 to 8 kg / cm ^2.
Perform pressure steaming for 5 minutes to remove excess fat such as bone marrow fluid.
Removed 0-90%. Next, the pressure steamed bone was directly cooled by a vacuum drying method. On the other hand, the katsuobushi, mirin-like seasoning, and vitamins A and E were added to the miso in small amounts to prepare well-kneaded miso miso, and each of the cooled bones was coated with the miso miso one by one with a putty. As the amount of application, 0.1 to 25 g of the bone was putty-coated. After coating, put each one in a heat-resistant bag, vacuum-pack and put in a retort kettle at a heating temperature of 120-130 ° C for 1.5-
The product was obtained by heating and pressurizing at a pressure of 4 kg / cm ² for 20 to 60 minutes, gradually cooling and then slowly watering. It was found that the pet feed produced as described above was also extremely suitable for pets as in Examples 1 and 2. Further, it was found that the water content was further reduced by 7 to 12% as compared with refrigeration and cooling, and the feed had high water activity and excellent storage stability. In addition, confirmation was performed using the femurs of cattle and sheep frozen after disassembling in the same manner as in this example, but the same results as in this example were obtained.

(Embodiment 4) 200 ribs of cattle immediately after dismantling were prepared, and 45 parts of sodium hypochlorite was added in the blood removal washing step.
It was immersed in cold water containing 65 ppm to remove blood, and was washed. Then, in a pressure cooker 100-120 ℃
At a heating temperature of 0.6-2 kg / cm ^{2 and} a pressure of about 15-30
Pressure steaming treatment was carried out through steam for minutes to remove fat contents such as bone marrow. Then, the pressure steamed bone was rapidly cooled by a vacuum cooling method and then cut into a length of 7 ± 1 cm. The cooled bone was cut cleanly without solidification of the bone marrow and no outflow. On the other hand, 5 pieces of cut bones are packed in a retort pouch, vacuum-packed and placed in a retort kettle.
The heating and pressing treatment was performed at a heating temperature of 00 to 140 ° C. and a pressure of 1.01 to 4 kg / cm ² for 20 to 60 minutes. The product was taken out from the retort kettle and cooled as it was in the retort pouch to obtain a product.
The pet feed of this example has a crude fat content of 4 to 9%.
It turned out to be extremely low. In addition, the content of crude protein, phosphorus, and calcium was high, and it was highly evaluated by veterinarians. The pet feed produced as described above is generally tasted and tasted without the effects of the first embodiment, no fear of adult diseases such as hypertension and the like regardless of age and breed. I understand.

(Example 5) 200 frozen femur bones of pigs were prepared, and soaked in cold water containing 45 to 65 ppm of sodium hypochlorite to remove blood while thawing the blower, and washed. Then, after cutting to 6 ± 1 cm, put 5 pieces each in a heat resistant bag and vacuum pack,
Put in a retort kettle at a heating temperature of 120-130 ° C for 1.5
A heat and pressure treatment was performed at a pressure of up to 4 kg / cm ² for 20 to 60 minutes, followed by slow cooling and then slow water removal to obtain a product. The pet feed of this example was found to have a crude fat content of 8 to 18%. It was found that the pet feed produced as described above also has the same effects as in Example 1 and is a very suitable feed for pets. It was also found that the steaming process and the cooling process were omitted, so that a large-scale manufacturing facility was not required, and the productivity was high and the mass productivity was improved.

Example 6 10 kg of fish bones of various sizes, which were grated into three pieces, were prepared and washed with water. Next, put this bone in a pan, add 2 g of salt to 98 g of bone, bag it in a retort pouch, seal it by degassing, sterilize the retort, let it taste penetrate, and then quickly cool to obtain the product. It was
The animal feed for pets produced as described above had appropriate softness, and a safe animal feed for pets that did not damage the internal organs of the pet was obtained. The taste of pets was satisfied with a seasoning mainly consisting of salt, which was appetizing.

[0022]

As described above, according to the present invention, it is possible to realize a pet animal feed and a method for producing the same, which can achieve the following excellent effects. (1) Since the taste of unseasoned bone itself can be tasted, it has a wild taste and can relieve stress by chewing and prevent gastrointestinal disorders. (2) Since bone does not contain sugars and the like, caries and the like do not occur on the teeth of pet animals, and there is no extra additive, which does not adversely affect pet animals. (3) It has excellent nutrient content, and since the bone is pressurized and heated by the retort, it does not hurt, and because it is moderately soft, it does not damage the gastrointestinal tract, etc., and has an appropriate hardness. As a result, the gums and lower jaw of pets can be strengthened and tartar can be removed. (4) Since the bone is moderately soft and degreased,
Workability and productivity can be improved. (5) By effectively utilizing large bones that have been incinerated as waste, it is possible to provide animal feeds for pets, which are excellent in nutritional content and texture and are suitable for mass production at low cost. (6) A variety of tastes can be prepared, such as bones to which seasonings such as miso, soy sauce, and salt are added or no seasonings are added, and various pet tastes can be satisfied. (7) Since the bone and the meat around the bone are integrated, the nutrients are excellent, and since the bone is soft, it can be swallowed without damaging the stomach and intestines. (8) Since the bone is soft and degreased, workability and productivity can be improved. (9) Since the rapid cooling is performed immediately after steaming, the quality immediately after seasoning can be maintained for a long period of time, and the shelf life is excellent, so that the flowability can be improved. (10) It is possible to provide animal feed for pets that is excellent in nutrient content, low in cost, and suitable for mass production, by effectively utilizing the bones of livestock that have been conventionally incinerated as waste.
