An example of a pet food containing such a flavoring is baked wheat gluten for pets, which is described in Patent Document 1. Patent Document 1 describes baked wheat gluten for pets that contains a flavoring that is palatable to pets. Patent Document 1 discloses that baked wheat gluten can be eaten by pets without difficulty. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-24046 A Summary of the Invention [Problem to be solved by the invention]

[0004] It is required that the pet food containing a fragrance can fully sense the aroma based on the fragrance when the pet eats the pet food. In addition, the pet food may be eaten by the pet immediately after production, but is often eaten after a certain period of storage. When storing the pet food, for example, the pet food may be stored in a state sealed in a packaging material. Even after the pet food is stored for a certain period of time, it is required that the quality of the pet food is not easily deteriorated by sealing it in a packaging material as described above. Furthermore, when the pet food containing a fragrance is stored in a state sealed in a packaging material, it is also required that the aroma based on the fragrance is maintained.

[0005] The present invention has been made in consideration of such circumstances, and aims to provide a pet food package that can effectively suppress the reduction in aroma due to flavorings contained in the pet food, even after the pet food has been stored together with an oxygen absorber. [Means for solving the problem]

[0006] As a result of various investigations, the present inventors have found that the above object can be achieved by the present invention described below.

[0007] The pet food package according to a first aspect of the present invention is a pet food package comprising: pet food containing a fragrance; a non-breathable packaging material that encloses the pet food; and an oxygen absorber that does not contain activated carbon that is contained within the packaging material.

[0008] According to this configuration, it is possible to provide a pet food package that can suitably suppress the reduction in the aroma due to the fragrance contained in the pet food even after the pet food is stored together with the oxygen absorber. Specifically, first, the oxygen concentration in the packaging material can be reduced by the oxygen absorber contained in the non-breathable packaging material. Therefore, the pet food sealed in the packaging material can be suppressed from being deteriorated in quality due to oxygen. Then, when an oxygen absorber that does not contain activated carbon is used as the oxygen absorber contained in the packaging material, it is possible to suppress the reduction in the aroma due to the fragrance contained in the pet food. Therefore, even after the pet food is stored in a sealed state in the packaging material, the pet food in the pet food package can maintain its quality and can also suitably maintain the aroma due to the fragrance. Therefore, the pet food package can more suitably maintain the aroma of the pet food sealed in the packaging material.

[0009] A pet food package according to a second aspect of the present invention is the pet food package according to the first aspect of the present invention, wherein the oxygen scavenger is an oxygen scavenger that absorbs oxygen and generates carbon dioxide.

[0010] With this configuration, even after the pet food has been stored together with the oxygen scavenger, it is possible to more suitably suppress the reduction in the aroma due to the fragrance contained in the pet food. In other words, it is possible to more suitably maintain the aroma of the pet food sealed within the packaging material. This is believed to be due to the following. When the oxygen scavenger absorbs oxygen, carbon dioxide is generated from the oxygen scavenger, so it is possible to suppress a drop in air pressure within the packaging material. It is therefore believed that it is possible to suppress the dissipation of the fragrance from the pet food due to a drop in air pressure. It is therefore believed that it is possible to more suitably maintain the aroma of the pet food sealed within the packaging material.

[0011] A pet food package according to a third aspect of the present invention is the pet food package according to the first or second aspect of the present invention, wherein the oxygen scavenger preferably comprises erythorbate.

[0012] According to this configuration, even after storage together with the oxygen scavenger, it is possible to more suitably suppress the reduction in the aroma due to the fragrance contained in the pet food. In other words, it is possible to more suitably maintain the aroma of the pet food enclosed in the packaging material. The oxygen scavenger containing erythorbate has a high oxygen absorption capacity, and when absorbing oxygen, carbon dioxide is generated from the oxygen scavenger. It is therefore believed that it is possible to more suitably maintain the aroma of the pet food enclosed in the packaging material.

[0013] A pet food package according to a fourth aspect of the present invention is the pet food package according to any one of the first to third aspects of the present invention, wherein the packaging material preferably comprises a metal foil.

[0014] According to this configuration, even after the pet food is stored together with the oxygen absorber, the reduction in the aroma due to the fragrance contained in the pet food can be more suitably suppressed. That is, the aroma of the pet food sealed in the packaging material can be more suitably maintained. Since the packaging material including the metal foil has a higher air impermeability (gas barrier property) of the packaging material, it is considered that not only can the oxygen absorber be absorbed suitably, but also the fragrance can be more suitably suppressed from diffusing from the pet food. In addition, since the packaging material including the metal foil has a high light blocking property, it is considered that the deterioration of the quality of the pet food can be more suitably suppressed, and the fragrance can be more suitably suppressed from diffusing from the pet food. Therefore, even after the pet food is stored in a sealed state in the packaging material, the pet food in the pet food package can more suitably maintain its quality and the aroma due to the fragrance can be more suitably maintained.

[0015] A pet food package according to a fifth aspect of the present invention is the pet food package according to any one of the first to fourth aspects of the present invention, wherein the pet food is pet jerky.

[0016] According to this configuration, even after the pet jerky is stored together with an oxygen absorber, the reduction in the aroma due to the flavoring contained in the pet jerky can be more suitably suppressed. That is, even if the pet food is a pet jerky, the aroma due to the flavoring can be suitably maintained. Specifically, even if a flavoring is contained in pet jerky, the flavoring tends to be relatively easily dispersed and the aroma due to the flavoring tends to be easily reduced, but the pet food package can suitably maintain the aroma due to the flavoring.

[0017] A pet food package according to a sixth aspect of the present invention is the pet food package according to any one of the first to fifth aspects of the present invention, wherein the flavoring is attached to the surface of the pet food.

[0018] According to this configuration, even after the pet food having a flavoring attached to its surface is stored together with an oxygen scavenger, the reduction in the aroma due to the flavoring contained in the pet food can be more suitably suppressed. That is, even if the pet food has a flavoring attached to its surface, the aroma due to the flavoring can be suitably maintained. Specifically, the flavoring attached to the surface of the pet food is more likely to dissipate than the flavoring contained inside the pet food. Pet food having a flavoring attached to its surface tends to have at least the flavoring attached to the surface dissipate easily, and the aroma due to the flavoring is easily reduced, but the pet food package can suitably maintain the aroma due to the flavoring. Effect of the Invention

[0019] According to the present invention, it is possible to provide a pet food package that can effectively suppress the reduction in the aroma due to the flavoring contained in the pet food, even after the pet food has been stored together with an oxygen scavenger. [Brief description of the drawings]

[0020] [Figure 1] FIG. 1 is a schematic cross-sectional view showing an example of a pet food package according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] As described above, it is considered that pet food consumed by pets (pet animals) such as dogs and cats contains a fragrance (flavor) to enhance its palatability. When producing pet food containing a fragrance, for example, it is considered that the fragrance is contained (kneaded) in the raw material. When the drying conditions during production are mild, for example, when the drying temperature is low or the drying time is short, the pet food obtained in this way can preferably exhibit the aroma based on the fragrance. For example, confectionery such as boro may be dried at 130 to 180°C for about 40 minutes, and artificial gum may be dried at 60 to 70°C for about 3 to 4 hours. In such a case, the obtained pet food can preferably exhibit the aroma based on the fragrance. On the other hand, when producing pet jerky, for example, it may be dried at 60 to 70°C for about 8 to 9 hours. In addition, chicken fillet chips made from chicken fillet and chicken fillet-wrapped gum made by wrapping chicken fillet in artificial gum may require a relatively long drying time during production. In such cases, the inventors have found that even if the raw material contains a flavoring, the resulting pet food tends to have an insufficient aroma based on the flavoring. As a countermeasure to this, it is possible to increase the amount of flavoring contained in the raw material, but the inventors have found that if the amount of flavoring is increased to a level that allows the aroma based on the flavoring to be fully exhibited, the preferences for other aspects such as taste will decrease. The inventors have also found that the flavoring may adhere to the inside of the dryer used for the drying, and when other products are dried, the flavor may transfer to the other products. Therefore, the inventors have considered adding a flavoring to the pet food after drying. The inventors have found that the pet food obtained in this manner can favorably exhibit the aroma based on the flavoring. However, the inventors have discovered that even in pet foods that can favorably exhibit an aroma based on such fragrances, when the pet food is sealed in a packaging material and stored together with an oxygen scavenger contained in the packaging material, depending on the type of packaging material and the type of oxygen scavenger, the pet food removed from the packaging material may have less of the aroma based on the fragrance contained therein.

[0022] Therefore, the present inventors conducted various studies and found that, when a non-breathable packaging material is used as the packaging material and an oxygen absorber containing no activated carbon is used as the oxygen absorber contained in the packaging material, not only can the deterioration of the quality of the pet food be suppressed, but also the reduction in the aroma due to the flavor contained in the pet food can be suppressed, leading to the invention described below. Furthermore, pet foods to which flavorings are added later tend to have a reduced aroma due to the flavoring, since the flavoring is not contained inside the pet food but is attached to the surface. Even with such pet foods, when a non-breathable packaging material is used as the packaging material and an oxygen absorber containing no activated carbon is used as the oxygen absorber contained in the packaging material, the reduction in the aroma due to the flavoring contained in the pet food can be suppressed, and therefore the inventors found that the reduction in the aroma due to the flavoring can be suppressed even for pet foods containing a flavoring inside.

[0023] Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to these.

[0024] As shown in FIG. 1, a pet food package 10 according to an embodiment of the present invention includes pet food 1, a packaging material 2 that encloses the pet food, and an oxygen absorber 3 contained within the packaging material 2. FIG. 1 is a schematic cross-sectional view showing an example of the pet food package 10 according to the present embodiment. The packaging material 2 is a non-breathable packaging material. The oxygen absorber 3 is an oxygen absorber that does not contain activated carbon. With such a pet food package 10, the oxygen absorber 3 is contained in the non-breathable packaging material 2, so that the oxygen concentration within the packaging material 2 can be reduced. As a result, the quality deterioration of the pet food 1 enclosed in the packaging material 2 is suppressed due to oxygen. The pet food 1 also contains a fragrance. Even after the pet food 1 containing such a fragrance is enclosed in the packaging material 2 and stored, the scent based on the fragrance contained in the pet food 1 can be suitably maintained by using an oxygen absorber that does not contain activated carbon as the oxygen absorber 3. Therefore, the pet food package 10 can suitably suppress the reduction in the aroma due to the flavoring contained in the pet food 1 even after the pet food 1 has been stored together with the oxygen absorber 3 .

[0025] The pet food 1 is not particularly limited as long as it contains a flavoring. The pet food 1 may be, for example, a pet food containing a flavoring inside the pet food, such as a pet food obtained by kneading a flavoring into a pet food ingredient and using the ingredient kneaded with the flavoring. The pet food 1 may also be a pet food with a flavoring attached to the surface, such as a pet food obtained by adding a flavoring to a pet food. The pet food 1 may also be a pet food containing a flavoring inside the pet food and with a flavoring attached to the surface, such as a pet food obtained by adding a flavoring to a pet food containing a flavoring inside the pet food. When a flavoring is attached to the surface of the pet food, the pet food can preferably exhibit a scent based on the flavoring. Furthermore, the flavoring attached to the surface of the pet food is more likely to dissipate than the flavoring contained inside the pet food. Pet food with a flavoring attached to the surface tends to have a reduced scent based on the flavoring because at least the flavoring attached to the surface is more likely to dissipate, but the pet food package 10 can preferably maintain the scent based on the flavoring. From these points of view, it is preferable that the pet food 1 provided in the pet food package 10 has a flavoring attached to its surface.

[0026] The flavoring is not particularly limited as long as it can be used by being contained in pet food. Examples of the flavoring include food additives and flavors (flavors) that are preparations thereof used for the purpose of imparting or enhancing aroma in the manufacturing or processing process of food. The flavoring may be in a liquid form or in a solid form such as a powder. Examples of the liquid flavoring include butter essence (butter extract), butter oil (butter essential oil), butter flavor extract (butter flavor oil), fresh cream, sour cream, raw milk, milk, concentrated milk, condensed milk, vanilla essence (vanilla oil), lemon oil, orange oil, peach flavor oil, mint essence (mint oil), and coffee flavor oil. Examples of the solid flavoring include whole milk powder, skim milk powder, sweetened milk powder, cream powder, cheese powder, butter powder, whey powder, buttermilk powder, yogurt powder, casein, lactose, peanut butter powder, sweet potato powder such as red sweet potato powder and purple sweet potato powder, potato powder, corn powder such as sweet corn powder and purple corn powder, beet powder, almond powder, mango powder, carrot powder such as black carrot powder, butterfly pea powder, pumpkin powder, tomato powder, spinach powder, beet powder, burdock powder, edamame powder, radish powder such as red radish powder, strawberry powder, potage powder, pudding powder, oyakodon powder, takoyaki powder, vanilla powder, caramel powder, maple syrup powder, powdered ketchup, chicken powder, and beef powder.

[0027] The pet food (for example, pet food before adding flavoring) is not particularly limited. If the pet food 1 is a pet food containing a flavoring inside the pet food, such as a pet food obtained by kneading a flavoring into a pet food ingredient and using the ingredient kneaded with the flavoring, the pet food can be obtained by kneading the flavoring into the ingredient. If the pet food 1 is a pet food with a flavoring attached to the surface, such as a pet food obtained by adding a flavoring to a pet food, the pet food can be obtained as a general pet food. Examples of the pet food include confectionery such as boro, pellet-shaped pet food, chunk-shaped pet food, artificial gum, pet jerky, pet biscuits, chicken breast chips made from chicken breast, and chicken breast wrapped gum in which chicken breast is wrapped around artificial gum. Even if a flavoring is contained in pet jerky, the flavoring tends to be relatively easily diffused and the aroma based on the flavoring tends to be easily reduced, but the pet food package 10 can favorably maintain the aroma based on the flavoring. From this point of view, among the pet foods, pet jerky is preferable as the pet food 1 provided in the pet food package 10. Examples of the pet jerky include jerky obtained by crushing raw meat to form a paste-like dough into a predetermined shape and then drying it. In addition, the type of meat of the pet jerky is not limited, and examples of the pet jerky include pet jerky made by drying livestock meat such as chicken, pork, and beef, and fish meat, and more specifically, chicken jerky, beef jerky, pork jerky, fish jerky, and mutton jerky. Examples of the chicken jerky include jerky made from chicken breast (chicken breast jerky) and jerky made from chicken breast.

[0028] The packaging material 2 is not particularly limited as long as it is capable of enclosing pet food and is non-breathable. Here, non-breathable means that it does not allow gas such as air to pass through, and the degree of air permeability is very low or almost non-breathable compared to packaging materials made of nonwoven fabrics. Examples of materials constituting the packaging material 2 include films, metallized films, and metal foils. Among these, metallized films and metal foils are preferred, and metal foils are more preferred, because they have high non-breathability and can improve the storage stability of pet food. In addition, the packaging material 2 includes packaging materials containing the materials constituting the packaging material 2, specifically, packaging materials containing films, packaging materials containing metallized films, and packaging materials containing metal foils, and is preferably made of the materials constituting the packaging material 2. Examples of packaging materials made of the materials constituting the packaging material 2 include packaging materials made of films, packaging materials made of metallized films, and packaging materials made of metal foils. Among these, packaging materials made of metallized films and packaging materials made of metal foils are preferred, and packaging materials made of metal foils are more preferred. The packaging material 2 may be, for example, a bag-shaped packaging material capable of accommodating pet food and capable of being sealed. The film is not particularly limited as long as it is a film capable of forming a packaging material capable of encapsulating pet food, and may be, for example, a polyester film such as a polyethylene terephthalate (PET) film, and a polyolefin film such as a polyethylene (PE) film. The metal-deposited film is not particularly limited as long as it is a metal-deposited film capable of forming a packaging material capable of encapsulating pet food, and may be, for example, a film in which a metal such as aluminum is deposited on the film. The metal foil is not particularly limited as long as it is a metal foil capable of forming a packaging material capable of encapsulating pet food, and may be, for example, an aluminum foil. The packaging material 2 is preferably a bag made of aluminum foil that can be sealed.

[0029] The oxygen absorber 3 is not particularly limited as long as it is an oxygen absorber that can absorb oxygen and does not contain activated carbon. By storing the oxygen absorber 3 in the packaging material 2, oxygen in the space wrapped by the packaging material 2 can be absorbed, and deterioration of the pet food 1 enclosed in the packaging material 2 due to oxygen can be suppressed. The oxygen absorber 3 may be an oxygen absorber containing an inorganic material, an oxygen absorber containing an organic material, or an oxygen absorber containing an inorganic material and an organic material. Examples of the inorganic material include metal powder such as iron powder, silicon dioxide, sodium chloride, calcium hydroxide, hydrogen chloride, sulfite, hydrogen sulfite, dithionite, and thiosulfate. Examples of the organic material include reducing sugars such as L-ascorbic acid, L-ascorbate, erythorbic acid, erythorbate, glucose, reducing polyhydric phenols such as catechol and pyrogallol, and polyhydric alcohols such as ethylene glycol and glycerin. Among the oxygen absorbers, the oxygen absorber 3 is preferably an oxygen absorber that absorbs oxygen and generates carbon dioxide. When the oxygen absorber absorbs oxygen, carbon dioxide is generated from the oxygen absorber, so that the decrease in air pressure inside the packaging material can be suppressed. From this, it is considered that the dissipation of the flavor from the pet food due to the decrease in air pressure can be suppressed. Therefore, it is considered that the scent of the pet food sealed in the packaging material can be more suitably maintained. Among the oxygen absorbers, the oxygen absorber 3 is preferably an oxygen absorber containing an erythorbate salt, and more preferably an oxygen absorber containing hydrogen chloride and an erythorbate salt, because it not only absorbs oxygen but also generates carbon dioxide when absorbing oxygen. Furthermore, the oxygen absorber 3 may be made of a material capable of absorbing oxygen, or may be a material capable of absorbing oxygen housed in a packaging material (packaging material for oxygen absorber) separate from the packaging material 2. That is, the oxygen absorber 3 may be an oxygen absorber housed in a packaging material for oxygen absorber. The packaging material for housing the oxygen scavenger (packaging material for oxygen scavenger) is not particularly limited as long as it is, for example, a packaging material that has breathability and prevents the housed oxygen scavenger from leaking out.Materials constituting the oxygen absorber packaging material include paper, polyolefins such as polyethylene (PE), and polyesters such as polyethylene terephthalate (PET), etc. The oxygen absorber packaging material may be a laminate of these materials, and for example, a packaging material in which PET, paper, and PE are laminated is preferable.

[0030] The method for producing the pet food package is not particularly limited as long as the pet food package can be produced. For example, a method in which a predetermined amount of the pet food is placed in the packaging material containing the oxygen scavenger and the packaging material is sealed in this state can be mentioned.

[0031] The present invention will be described in more detail below with reference to examples, but the scope of the present invention is not limited to these examples. EXAMPLES

[0032] [Example 1, Example 2, and Comparative Example] In this embodiment, the pet food, packaging material, and oxygen absorber used in the pet food package will be described.

[0033] (Pet food) Chicken fillet jerky (chicken fillet jerky manufactured by Marukan Co., Ltd.) was used as pet food immediately after adding butter flavor oil as a flavoring.

[0034] (packaging material) As the packaging material, a bag-shaped packaging material made of aluminum foil was used.

[0035] (Oxygen absorber) Oxygen absorber A: An oxygen absorber that absorbs oxygen and releases carbon dioxide, and does not contain activated carbon (Keepit YC type manufactured by Drenchy Co., Ltd., an oxygen absorber containing hydrogen chloride and sodium erythorbate in a breathable packaging material made of laminated PET, PAP, and PE). Oxygen absorber B: An oxygen absorber that absorbs oxygen (does not release carbon dioxide) and does not contain activated carbon (Ageless GLS type manufactured by Mitsubishi Gas Chemical Co., Ltd.) Oxygen absorber C: An oxygen absorber that absorbs oxygen (does not release carbon dioxide) and contains activated carbon (Keepit L-PW type manufactured by Drenchy Co., Ltd., an oxygen absorber containing silicon dioxide, sodium chloride, calcium hydroxide, activated carbon, and iron powder in a breathable packaging material made of laminated PET, paper, and PE). [Example 1] As shown in Fig. 1, the oxygen absorber A was placed in the packaging material, and then the pet food was placed in the packaging material, and the packaging material was sealed. In this way, a pet food package in which the pet food and the oxygen absorber A were enclosed in the packaging material was obtained.

[0036] [Example 2] A pet food package was obtained in which the pet food and the oxygen absorber B were enclosed in the packaging material in the same manner as in Example 1, except that the oxygen absorber B was used instead of the oxygen absorber A.

[0037] [Comparative Example] A pet food package was obtained in which the pet food and the oxygen absorber C were enclosed in the packaging material in the same manner as in Example 1, except that the oxygen absorber C was used instead of the oxygen absorber A.

[0038] [evaluation] The pet food packages according to Example 1, Example 2, and the Comparative Example were stored for 10 days and evaluated as follows.

[0039] The packaging material of the pet food package was opened, and the gas inside the packaging material was once discharged, after which five evaluators evaluated the aroma emanating from the pet food itself inside the pet food package according to the following criteria. As described above, the pet food in the pet food package was the one immediately after the addition of fragrance (flavor), and therefore the pet food had been in the packaging material for 10 days after the addition of fragrance (flavor).

[0040] If the scent was strong, it was rated as a "4"; if the scent was identified and the scent was clearly detected, it was rated as a "3"; if the scent was faint but the scent could be identified, it was rated as a "2"; if the scent was detected but the scent could not be identified, it was rated as a "1"; and if no scent was detected at all (it was fragrance-free), it was rated as a "0".

[0041] As a result, the five evaluators gave the pet food package according to Example 1 a rating of "3," "3," "4," "3," and "3," respectively. The total rating of the five evaluators was "16."

[0042] The five evaluators gave the pet food package of Example 2 a rating of "3," "2," "3," "2," and "2," respectively. The total rating of the five evaluators was "12."

[0043] The five evaluators gave the pet food packages according to the comparative example ratings of "2," "1," "2," "1," and "1," respectively. The total rating of the five evaluators was "7."

[0044] From the above, it was found that when oxygen absorbers not containing activated carbon (oxygen absorber A and oxygen absorber B) were used as oxygen absorbers contained in the packaging material enclosing the pet food containing a fragrance (Examples 1 and 2), the pet food stored in the packaging material could have a more fragrant aroma than when an oxygen absorber containing activated carbon (oxygen absorber C) was used (Comparative Example). Therefore, it was found that by using an oxygen absorber not containing activated carbon as an oxygen absorber contained in the packaging material enclosing the pet food containing a fragrance, it was possible to suitably suppress the reduction in aroma due to the fragrance contained in the pet food, even after the pet food was stored together with the oxygen absorber.

[0045] Furthermore, it was found that when an oxygen absorber that absorbs oxygen and releases carbon dioxide (oxygen absorber A) was used (Example 1) among oxygen absorbers that do not contain activated carbon, the scent of the pet food stored in the packaging material could be felt more clearly than when an oxygen absorber that does not release carbon dioxide (oxygen absorber B) was used (Example 2). From this, it was found that an oxygen absorber that absorbs oxygen and releases carbon dioxide and does not contain activated carbon is preferable as the oxygen absorber. [Explanation of symbols]
