Hereinafter, a method for preparing feed for dogs according to a preferred embodiment of the present invention and dog feed prepared thereby will be described in detail with reference to the accompanying drawings.

1 is a manufacturing process (process) showing a method for producing feed for dogs according to a preferred embodiment of the present invention, (a) preparing raw materials for dog feed in a weight ratio of 5.5 to 6.5: 1 for cattle liver and livestock raw materials, and medium moisture Preparing the content raw material and the health additive as a pet feed material (S10), (b) the step of defrosting the frozen material of the prepared pet feed material and mixing in a blender to produce a blended meat (S20, S30), (c ) Step of molding the produced mixed meat into semi-finished products through nozzles at regular intervals (S40), (d) Step of preparing dog food by drying the molded semi-finished products in a dryer under preset drying conditions (S50), (e) It includes the step of cooling the prepared dog food in a cooler to a predetermined cooling condition (S60), (f) cutting the cooled dog food into a predetermined length with a cutter (S70).

A detailed description of the method for preparing feed for dogs according to the present invention configured as described above is as follows.

First, in step S10, which is the first process, cattle liver and livestock raw materials, which are main raw materials for dog feed, are prepared in a weight ratio of 5.5 to 6.5: 1, and intermediate moisture content raw materials and health additives are prepared as pet food materials.

For example, the main ingredients of dog feed are beef liver and livestock, but based on the total weight of the mixed meat, 30 to 50% by weight of cattle liver, 5 to 8% by weight of livestock, 10 to 14% by weight of oligosaccharide as a medium moisture content raw material, 6 to 20% by weight of vegetable protein, 0.02 to 2% by weight of glucosamine for joint nutrition, 0.02 to 2% by weight of chondroitin for joint nutrition, 0.05 to 2% by weight of complex vitamins and minerals, 1 to 20% by weight Prepare the additive as dog food.

Here, cattle liver is not particularly limited, and conventional cattle liver used in the manufacture of dog food is used, and meat meat is not particularly limited, and any one of chicken, duck, pig, cow, etc., or at least two or more livestock It can be mixed and used. In the present invention, it is assumed that duck meat is used for convenience of explanation.

In addition, the vegetable protein may be any of the known vegetable proteins, but in the present invention, it is assumed that soybeans and soybean meal are used as examples.

In addition, as an additive, cereal powders such as wheat flour, soybean flour, barley flour, rice flour, mung bean flour, sorghum flour, crude flour, oat flour, millet flour, and blood flour, or extracts may be used.

In addition, glucosamine and chondroitin used for joint nutrition are already known in academia. For example, as nutritional data, "Glucosamine sulfate and Ghondroitin sulfate are effective in treating osteoarthritis (Youngho Lee, Jongdae Ji, Kwankyu Song / Department of Rheumatology, College of Medicine, Korea University. / You can refer to the paper titled "Journal of the Korean Rheumatology Society (vol. 15. No. 3, September, 2008).

According to the above paper, glucosamine and chondroitin are known to be effective in treating knee and osteoarthritis.

In addition, saccharides such as oligosaccharides, which are the intermediate moisture content raw materials, play a role of suppressing the activity of moisture in the dog's feed, and the moisture activity of the dog's feed is lowered by the components of the oligosaccharide, and at the same time, the deterioration of the dog feed by microorganisms is prevented. It suppresses, and provides convenience for consumption by giving sufficient flexibility to the product due to the maintenance of an appropriate moisture content. Here, the medium moisture refers to a moisture content that contains a large amount of moisture than normal dry dog food and has the same resistance as dry food against the propagation of microorganisms. The medium moisture content usually means containing 10%-40% of moisture. In general or conventional dog food, when dried, the moisture content is less than 10% by weight, and it is very hard and it is difficult for dogs to consume it. However, in the present invention, since the prepared dog food is in the form of medium moisture, it has a soft texture. To make it easier to ingest.

The water activity (Aw) of dog food can be expressed as the ratio (Aw = P/P _o ) of the water vapor pressure (P) in the dog's food to the vapor pressure (P _o ) of pure water measured at the same temperature.

According to this, moisture in dog food is combined with the ingredients of dog food, and its fluidity is restricted, and the original physical and chemical activity of moisture is reduced due to this effect, and the degree of reduction when pure water is considered as 1 is called water activity. define. As a method of lowering the water activity, a typical method commonly used is to add a suitable solute that reduces the activity of water, and in the present invention, a saccharide such as oligosaccharide was used to lower the water activity. In the present invention, a dog feed having a moisture content of 20 to 26% by weight is prepared using oligosaccharide.

Subsequently, in step S20, the frozen material of the prepared dog feed material is thawed. Here, if there is no frozen material, the defrosting process can be omitted.

Next, the dog feed material prepared in step S30 is blended in a blender to produce blended meat. Here, the blended meat is produced by mixing the beef liver and livestock raw materials in a weight ratio of 5.5 to 6.5:1. The blending method is to produce blended meat by putting all of the dog ingredients into the blender, and then kneading in a form of stirring for 20 to 40 minutes.

When the blended meat is generated, the blended meat produced in step S40 is molded into a semi-finished product using a molding machine. Here, nozzles at regular intervals may be used as the molding machine. Here, as a molding method, injection molding can be used. For example, the mixed meat is molded into a semi-finished product through a method of injecting the mixed meat into a thin strip of 4 to 20 strands or more using a molding machine such as a screw pump. That is, it may be injection-molded to have a cross section of an ellipse, a circle, or a rectangle having a horizontal diameter of 13 mm and a vertical diameter of 6 mm. Here, the cross section of an ellipse, circle, or rectangle refers to a cross section whose diameter in one direction is shorter than the diameter in the other direction perpendicular to it, and its outer circumferential surface does not necessarily have to be smooth, and the molded blended meat is convex and concave. It may be molded to have one or more faces formed alternately. For example, the upper surface of the blended meat may be formed so that the convex portion and the concave portion are alternately formed, and the lower surface may be formed to be a smooth surface. The height difference between the convex portion and the concave portion may be 1-2 mm.

After the blended meat is molded, the semi-finished product molded as in step S50 is dried in a dryer under predetermined drying conditions to prepare a dog feed. Here, the dryer may use a hot air dryer, and the drying condition may be a temperature of 80°C to 120°C, and a drying time may be 1 to 3 hours.

In order to establish an optimal drying condition suitable for the characteristics of dog food, the present inventor conducted a drying experiment at different temperatures and times. In particular, the experiment was conducted using a "low temperature long time" drying method and a "high temperature short time" drying method.

First, as a "low temperature long time" drying method, the drying temperature was set to 40-60 °C, and after drying for 12-15 hours, the physical properties of the dog food were examined. As a result of the review, the inside and the surface of the pet food were all smoothly dried, and the overall product showed a tendency to be stiff, and the moisture content was 12 to 15%. Accordingly, in the case of "low temperature long time" drying, the texture was hardly dried, and thus it was not suitable for realization of the "soft" texture pursued by the present invention.

On the contrary, the high-temperature short-time drying method of drying for 15 to 30 minutes at a temperature of 140-160 °C to extremely increase the drying temperature and shorten the time is generally used in a method of baking "cookies" or "bread". In the preliminary experiment, browning of the surface proceeded severely and the edges of the pet food were burned, so it was found to be inappropriate.

Therefore, the present inventors implemented the appropriately soft texture pursued in the present invention by using a "high temperature short time" drying method.

Drying the drying temperature and time at 80℃-120℃ for 1 to 3 hours corresponds to the "high temperature short time" drying method. In the present invention, when the dog feed is dried for a "high temperature and short time", a phenomenon called "surface hardening (case hardning)" appears in food terms. The mechanism of the "surface hardening" phenomenon means that the surface portion of the dog food is exposed to hot air at a high temperature for a short time, so that the phenomenon of "reduction rate drying" that appears at the beginning of drying proceeds rapidly. In the present invention, oligosaccharides present as components of dog food, protein components contained in cattle liver and meat, etc. act to form a "hard film" on the surface of dog food. Therefore, due to the influence of the "film" formed in this way, water evaporation inside the dog feed is suppressed, so that the physical properties inside the dog feed are moist and can produce a soft product.

The dried semi-finished product has a moisture content of 20 to 26% by weight.

The dog feed after drying is allowed to cool in a cooler in step S60 under a predetermined cooling condition. Here, the cooling condition may be a product temperature of 30°C or less.

Next, the dog feed cooled in step S70 is cut to a certain length with a cutter. For example, dog food can be cut into a certain size by passing it continuously between blades that move up and down. At this time, by adjusting the moving speed of the conveyor, it is possible to adjust the cutting length of the dog food. The length of dog food can be appropriately adjusted in consideration of the desired texture. For example, it can be cut to lengths of 0.1-2.5 cm.

2A and 2B are photographs of dog food prepared in steps S10 to S70 as described above.

As shown in FIG. 2A, the outer circumferential surface may be manufactured in a smooth form, and as shown in FIG. 2B, one surface may be manufactured to have a smooth cross-section and the other surface may be manufactured such that a concave portion and a convex portion are provided.

Although the invention made by the present inventor has been described in detail according to the above embodiment, the present invention is not limited to the above embodiment, and it is common knowledge in the art that various changes can be made without departing from the gist of the invention. It is self-evident to those who have
