Description

[Technical Field]

[0001] The present invention relates to a method for producing pet food and pet cookies for cats, dogs, and the like. [Background technology]

[0002] Pet food and pet cookies are easily given to pets, but if they are not thoroughly sterilized, they can cause food poisoning, which can make your pet sick or even kill it.

[0003] For this reason, heat sterilization or secondary heating of ingredients has traditionally been recommended. However, in the pet food industry, sun drying and indoor secondary heating are the norm, and in 2019, one company was using a boiler for indoor secondary heating. However, due to a malfunction in the boiler, the temperature did not rise to 75°C, and the product was sold with bacteria still present, even though it should have been sterilized by secondary heating at a core temperature of 75°C for at least one minute to kill salmonella, at a core temperature of 85°C for at least one minute to kill norovirus, and at a core temperature of 95°C for other bacteria. This resulted in the ill health of over 60 dogs (15 of which died).

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2023-176761 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0006] The invention described in Patent Document 1 above relates to a method for manufacturing pet food, which is characterized by mixing a moisturizer or liquid into the pet food, but does not describe the heating temperature or the sterilization method using that.

[0007] The present invention relates to a means for properly and efficiently sterilizing pet food and pet cookies when they are produced. [Means for solving the problem]

[0008] (1) The present invention is a method for producing pet food, comprising: a cutting step of cutting raw materials for pet food to a predetermined size; a heating step of placing the raw materials on a wire rack and heating them at a temperature of 40°C to 100°C for 10 to 20 hours; a secondary heating step of heating the raw materials that have undergone the heating step at a temperature of 90°C to 130°C for 2 to 20 minutes; and a cooling step of cooling the raw materials that have undergone the secondary heating step. In the present invention, the raw material is heated at a temperature of 40 to 100°C for 10 to 20 hours in a heating process, and then heated at a temperature of 90 to 130°C for 2 to 20 minutes in a secondary heating process, thereby completely eliminating bacteria and other microorganisms present in the raw material.

[0009] (2) It is desirable that a thawing step be provided before the cutting step, in which the frozen raw material is thawed naturally or in running water. When the raw material is frozen, it can be smoothly cut into the desired shape and dimensions by thawing it naturally or in running water before the cutting step.

[0010] (3) In the cutting process, it is desirable to heat the material that is difficult to cut at a temperature of 70 to 80°C for 2 to 4 hours, cool it, and then cut it. Even if the raw material is difficult to cut, if it is heated (preheated) at a temperature of 70 to 80°C for 2 to 4 hours, the cells will be destroyed and it will become easier to cut.

[0011] (4) It is desirable that the raw materials be of animal or plant origin, or both. Suitable raw materials include animal-derived materials such as meat, skin, bones, nails, dairy products, and insects, as well as plant-derived materials such as vegetables, fruits, and seaweed, and even supplements.

[0012] (5) The present invention is a method for producing pet cookies, which comprises a forming step of mixing ingredients for pet cookies and then forming them into a flat plate; a heating step of heating the formed ingredients at a temperature of 100°C to 160°C while turning them over every 10 to 30 minutes; and a cooling step of cooling the ingredients that have been heated. In the present invention, the molded raw material is heated at a temperature of 100 to 160°C on both sides by turning it over every 10 to 30 minutes, and the raw material is cooled in a cooling process, thereby completely eliminating bacteria and other contaminants present in the raw material.

[0013] (6) The raw materials should preferably be grains, vegetables, and fruits. When fruit is used instead of sugar, which is mixed into ingredients to stimulate pets' appetites, the cookies inevitably contain a lot of moisture, but by using the secondary heating process described above to sufficiently evaporate the moisture, a secondary heated cookie can be created.

[0014] (7) The ratio of fruit to other ingredients should preferably be between 1:1 and 1:3. A ratio of fruit to other ingredients (mainly grains) of 1:1 to 1:3 will encourage a pet's appetite.

[0015] (8) Fruits should preferably be fresh. It is recommended to use fresh fruits as they are less likely to be sweet after secondary heating and powder processing. However, as fresh fruits have a high water content, they must be thoroughly heated in the secondary heating process described above. [Effects of the Invention]

[0016] According to the present invention, the raw materials can be heated sufficiently, so that they can be sterilized reliably, and the risk of causing health hazards to pets is reduced. [Brief explanation of the drawings]

[0017] [Figure 1] FIG. 1 is a block diagram of a manufacturing process for a pet food according to an embodiment of the present invention. [Figure 2] FIG. 1 is a block diagram of a manufacturing process for pet cookies according to an embodiment of the present invention.

[0018] Before describing the embodiments of the present invention, pet food and pet cookies will be described and the differences between them will be noted. First of all, pet food is a food product made to provide pets with the nutrients they need daily for their proper growth and health maintenance and improvement. It is generally made from ingredients such as grains, potatoes, starches, sugars, meat, seafood, vegetables, fruits, vitamins, minerals, and amino acids.

[0019] Next, pet cookies are a food that is often given to pets as a treat or training reward, and unlike cookies for humans, they are made with simple ingredients and are low in calories. In particular, dog and cat cookies are designed to support pet health by using specific ingredients (vegetables, meat, fish, etc.).

[0020] Another difference between pet food and pet cookies is that pet food is given as a staple food and focuses on providing nutrition and maintaining the health of pets, while pet cookies are given as snacks and serve as training and rewards. Therefore, pet cookies are generally made with simple ingredients and are low in calories.

[0021] Here, the manufacturing process of the pet food according to the embodiment of the present invention will be described with reference to FIG. Frozen meat, seafood, etc. are thawed in a thawing process by natural thawing or thawing under running water, and then cut into predetermined shapes and dimensions in a cutting process. In this case, when using hard raw materials such as bones that are difficult to cut, preheating the raw materials at a temperature of 70 to 80°C for 2 to 4 hours (preheating) before the cutting process destroys the cells, making them easier to cut.

[0022] Next, in the heating process, the cut raw material is placed on a wire rack in an oven and heated at a temperature of 40 to 100°C for 10 to 20 hours, followed by a second heating process in the same oven for 2 to 20 minutes. After heating, the pet food is completed by forced cooling or natural cooling in a cooling step.

[0023] Suitable raw materials include animal-derived materials such as meat, skin, bones, nails, dairy products, and insects, as well as plant-derived materials such as vegetables, fruits, and seaweed, and even supplements.

[0024] Next, the manufacturing process of the pet cookie according to the embodiment of the present invention will be described with reference to Fig. 2. After mixing the ingredients for the pet cookie, in the molding process, the mixture is poured into a mold and molded into a flat plate. Then, in the heating process, the formed raw material is placed on a wire rack inside an oven, and in the heating process, the raw material is heated at a temperature of 100 to 160°C, and is turned over every 10 to 30 minutes to heat both sides.Finally, the raw material that has undergone the heating process is cooled in a cooling process, and the pet cookies are completed. Suitable raw materials include wheat, vegetables, and fruits.
