Description
本発明は、例えば超小型犬やシニア犬等のように噛む力が弱い動物を対象とするペット用飼料の製造方法に関する。 The present invention relates to a method for producing a pet feed for animals that have a weak biting force, such as ultra-small dogs and senior dogs.
従来から、一般に、犬用として使用される牛革等の革等の原料から製造されるペット用飼料は、原料に水洗、脱灰、酸化及び漂白等の処理を施し、絞って脱水し、各形態に成型し、乾燥させたものが市販されている。また、その他にも、牛のアキレス腱や豚の耳等の原料を各種処理を経て最終的に乾燥させたペット用飼料も数多く市販されている。 Conventionally, pet feed manufactured from raw materials such as leather, such as cow leather that is generally used for dogs, is subjected to treatments such as washing, deashing, oxidation and bleaching on the raw materials, squeezed and dehydrated, and each form Molded into dried and dried. In addition, many pet feeds that are finally dried after various treatments of raw materials such as cattle Achilles tendon and pig ears are commercially available.
これらのペット用飼料は、腐食やカビ等による汚染を防ぐために脱水及び乾燥され、水分活性値を低く抑えたものであるため、水分含有量が少なく硬質であり、成型性に劣るため、超型犬や歯の弱い犬や顎の弱いシニア犬では、歯で強く噛むことができないため、ペット用飼料を十分に食することができない。また、歯の弱い犬やシニア犬の顎に過剰な負担がかかり、ストレスを却って増大させたりする。 These pet feeds are dehydrated and dried to prevent contamination due to corrosion, mold, etc., and the water activity value is kept low. Dogs, dogs with weak teeth, and senior dogs with weak jaws cannot chew their teeth strongly, so they cannot eat enough pet food. In addition, it places an excessive burden on the jaws of dogs with weak teeth and senior dogs, and increases them over stress.
これに対し、近年は犬のなかでも超小型犬に分類される犬が飼われている割合が高く、かかる超小型犬に食べさせるペット用飼料に対する需要が高くなってきている。 On the other hand, in recent years, the proportion of dogs classified as ultra-small dogs is high among dogs, and the demand for pet feed to be eaten by such ultra-small dogs is increasing.
そこで、例えば特許文献1(特開2000−175627号公報)では、床革を原料とした柔軟性のあるペット用飼料を得るための技術が提案されている。即ち、特許文献1においては、ポリオールとよばれる多価アルコールの湿潤剤が生皮によって取り込まれ、乾燥した後や長時間空気に晒された後でも柔らかさをとどめる生皮製品の提供を可能にしており、同時に水分含量の増加を可能にしている。 Therefore, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2000-175627) proposes a technique for obtaining a flexible pet feed using floor leather as a raw material. That is, in Patent Document 1, a polyhydric alcohol wetting agent called polyol is taken in by rawhide, and it is possible to provide a rawhide product that remains soft even after being dried or exposed to air for a long time. At the same time, the moisture content can be increased.
また、例えば特許文献2(特開2003−235468号公報)においては、原皮をスライスし、水戻し、脱灰、酸化、漂白等の化学処理を施して得られた床革に、革繊維分解酵素で処理する革繊維分解酵素処理工程と、前記革
繊維分解酵素処理工程により得られた中間処理革に多価アルコールを充填させる柔軟剤充填処理工程と、を含むペット用飼料の製造方法が提案されている。
Further, for example, in Patent Document 2 (Japanese Patent Application Laid-Open No. 2003-235468), a leather fiber-degrading enzyme is applied to floor leather obtained by slicing raw leather and subjecting it to chemical treatments such as rehydration, decalcification, oxidation, and bleaching. A method for producing a pet feed comprising a leather fiber-degrading enzyme treatment step treated with a softening agent filling treatment step of filling an intermediate treated leather obtained by the leather fiber-degrading enzyme treatment step with polyhydric alcohol is proposed. ing.
しかしながら、上記特許文献1における多価アルコールは、単に革に包含されているだけであり、かかる多価アルコールを革の内部や革繊維体にまで十分に浸透させることはできず、柔軟性を上げるという効果は十分でない。また、上記特許文献2においては、中間処理革に多価アルコールを充填させることは可能ではあるが、上記特許文献1の技術と同様に、特に牛のアキレス腱等の筋や豚の耳等の硬質部分を含む原料については一切検討されていない。 However, the polyhydric alcohol in Patent Document 1 is merely included in leather, and the polyhydric alcohol cannot be sufficiently permeated into the leather and the leather fiber body, thereby increasing flexibility. The effect is not enough. Further, in Patent Document 2, although it is possible to fill the intermediate-treated leather with polyhydric alcohol, in the same manner as the technique of Patent Document 1, it is particularly hard for muscles such as Achilles tendon of cattle and ears of pigs. The raw material including the part is not studied at all.
そこで、本発明の目的は、牛のアキレス腱等の筋や豚の耳等の硬質部分を含む原料からであっても、柔軟性に優れたペット用飼料を得ることのできるペット用飼料の製造方法を提供することにある。 Accordingly, an object of the present invention is to provide a pet feed production method that can obtain a pet feed excellent in flexibility even from a raw material containing a hard portion such as a muscle of a cow's Achilles tendon and a pig ear. Is to provide.
上記課題を解決するために、本発明者は、牛のアキレス腱等の筋や豚の耳等の硬質部分を含む原料を如何に処理すれば、これら硬質部分を含む原料から柔軟性に優れたペット用飼料を得ることができるのか、各処理工程の条件等について鋭意検討及び実験を繰り返した結果、洗浄工程と、所定の組成の水溶性処理液を用いる漬込み工程と、乾燥工程と、を経ることが有効であることを見出し、本発明を完成するに至った。 In order to solve the above-mentioned problems, the present inventor can treat a raw material containing a hard portion such as a muscle of a cow's Achilles tendon or a pig's ear to obtain a pet having excellent flexibility from the raw material containing the hard portion. As a result of intensive investigations and experiments on the conditions of each treatment process, etc., through a washing process, a soaking process using a water-soluble treatment liquid of a predetermined composition, and a drying process Has been found to be effective, and the present invention has been completed.
即ち、本発明は、(1)硬質部分を含む原料である牛のアキレス腱(牛筋)又は豚・羊の耳を水洗する洗浄工程と、(2)前記洗浄工程を経た前記原料を、プロピレングリコール及びグリセリンを含む水溶性処理液に浸漬する漬込み工程と、(3)前記漬込み工程を経た前記原料を乾燥させてペット用飼料を得る乾燥工程と、を含むこと、を特徴とするペット用飼料の製造方法を提供する。 That is, the present invention includes (1) a washing step of washing a cow's Achilles tendon (cattle muscle) or a pig / sheep ear , which is a raw material containing a hard part, and (2) the raw material that has passed through the washing step, And a dipping step of immersing in a water-soluble treatment solution containing glycerin, and (3) a drying step of drying the raw material that has passed through the dipping step to obtain a pet feed. A manufacturing method is provided.
このような構成を有する本発明のペット用飼料の製造方法によれば、洗浄工程において、牛のアキレス腱(牛筋)又は豚・羊の耳等の、硬質部分を有する原料に付着している切屑や異物等を除去することができ、漬込み工程において、前記原料に十分な柔軟性(特に乾燥後の柔軟性)を付与することができ、そして、乾燥工程において、適度な水分活性値と十分な柔軟性を有するペット用飼料を得ることができる。 According to the method for producing a pet feed of the present invention having such a configuration, chips adhering to a raw material having a hard portion, such as a cow's Achilles tendon (cattle muscle) or a pig / sheep ear, in the washing step. And foreign substances can be removed, the raw material can be given sufficient flexibility (especially after drying) in the dipping step, and an appropriate water activity value and sufficient in the drying step A pet food having flexibility can be obtained.
上記の本発明のペット用飼料の製造方法においては、前記漬込み工程(2)の前記水溶性処理液におけるプロピレングリコール及びグリセリンの体積比(プロピレングリコール:グリセリン)が1:4〜1:3である。 In the pet feed production method of the present invention, the volume ratio of propylene glycol and glycerin (propylene glycol: glycerin) in the water-soluble treatment liquid in the immersing step (2 ) is 1: 4 to 1: 3. .
本発明者は、特に上記水溶性処理液が上記組成を有する場合に、適度な水分活性値と十分な柔軟性を有するペット用飼料をより確実に得られることを、実験により確認している。 The present inventor has confirmed by experiments that a pet feed having an appropriate water activity value and sufficient flexibility can be obtained more reliably, particularly when the water-soluble treatment liquid has the above composition.

このような構成を有する本発明のペット用飼料の製造方法によれば、人間に対するのと同様の安全性を有し、腐敗が進行しにくいペット用飼料を、より確実に得ることができる。 According to the method for producing a pet feed of the present invention having such a configuration, it is possible to more reliably obtain a pet feed that has the same safety as that for humans and is less prone to decay.
本発明によれば、牛のアキレス腱(牛筋)等の筋や豚・羊の耳等の硬質部分を含む原料からであっても、柔軟性に優れたペット用飼料を得ることのできるペット用飼料の製造方法を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, even if it is from the raw material containing hard parts, such as muscles, such as a cow's Achilles tendon (cow muscle), and the ears of a pig and a sheep, it can obtain pet feed excellent in flexibility. A method for producing a feed can be provided.
以下において、本発明のペット用飼料の製造方法の一実施形態として、硬質部分を有する原料として牛のアキレス腱を用いたペット用飼料の製造方法について説明する。ただし、本発明はこれらのみに限定されるものではない。 Hereinafter, as an embodiment of the method for producing a pet feed of the present invention, a method for producing a pet feed using a cow's Achilles tendon as a raw material having a hard portion will be described. However, the present invention is not limited to these.
(1)洗浄工程
まず、本実施形態のペット用飼料の製造方法においては、硬質部分を有する原料として牛のアキレス腱を、水を用いて洗浄(水洗)する(洗浄工程)。例えば、多数の牛のアキレス腱を笊に入れて、牛のアキレス腱の上から水を流して洗浄すればよい。この洗浄工程では、原料である牛のアキレス腱に付着している切屑や異物を除去する。
(1) Washing process First, in the method for producing a pet feed of the present embodiment, a cow's Achilles tendon is washed (washed) with water as a raw material having a hard part (washing process). For example, a large number of cattle Achilles tendons may be placed in a cage and washed by flowing water over the cattle Achilles tendons. In this cleaning process, chips and foreign substances adhering to the Achilles tendon of the cow as a raw material are removed.
また、水を流しながら、ブラシ等で牛のアキレス腱の表面を掃除するのがより好ましい。牛のアキレス腱には、黒い炭状の異物が付着していることがあるため、かかる異物をより確実に除去するためにも、ブラシ等で掃除をするのが好ましい。 It is more preferable to clean the surface of the cow's Achilles tendon with a brush or the like while flowing water. Since black charcoal foreign matter may adhere to the Achilles tendon of the cow, it is preferable to clean with a brush or the like in order to remove such foreign matter more reliably.
なお、水洗に用いる水は、水道水でよく、蒸留水や純水であってもよい。また、原料である牛のアキレス腱は、洗浄工程に供する前において、乾燥した状態であっても生の状態であってもよい。 The water used for washing may be tap water, or distilled water or pure water. Further, the cow's Achilles tendon as a raw material may be in a dry state or a raw state before being subjected to the washing step.
(2)漬込み工程
次に、上記洗浄工程(2)を経た牛のアキレス腱を、プロピレングリコール及びグリセリンを含む水溶性処理液に浸漬する。
(2) Dipping step Next, the Achilles tendon of the cow that has undergone the washing step (2) is immersed in a water-soluble treatment solution containing propylene glycol and glycerin.
ここで用いる水溶性処理液は、プロピレングリコール及びグリセリンに加えて水などを含むため、水溶性と称している。当該水溶性処理液を用いることにより、牛のアキレス腱に十分な柔軟性(特に後述する乾燥工程後の柔軟性)を付与できることを、本発明者は実験により見出した。したがって、前記水溶性処理液は、牛のアキレス腱に対する柔軟剤とも言える。 The water-soluble treatment liquid used here is called water-soluble because it contains water in addition to propylene glycol and glycerin. The present inventor has found through experiments that a sufficient flexibility (especially after the drying step described later) can be imparted to the bovine Achilles tendon by using the water-soluble treatment liquid. Therefore, it can be said that the water-soluble treatment liquid is a softening agent for bovine Achilles tendon.
当該水溶性処理液に含まれるプロピレングリコール及びグリセリンは、多価アルコールである。多価アルコールには、上記特許文献2にも記載されているように、例えば、グリセリン、キシリトール、マンニトール、ソルビトール、エリスリトール及びプロピレングリコール等、種々のものが挙げられるが、特にプロピレングリコール及びグリセリンの組合せを用いることが、牛のアキレス腱に十分な柔軟性(特に後述する乾燥工程後の柔軟性)を付与するという観点から好適であることを、本発明者は見出した。 Propylene glycol and glycerin contained in the water-soluble treatment liquid are polyhydric alcohols. Examples of the polyhydric alcohol include various substances such as glycerin, xylitol, mannitol, sorbitol, erythritol, and propylene glycol, as described in Patent Document 2 above. Particularly, a combination of propylene glycol and glycerin. The present inventor has found that it is suitable to use a sufficient amount of softness (particularly softness after the drying process described later) for the Achilles tendon of cattle.
プロピレングリコール及びグリセリンを含む水溶性処理液を、漬込み工程(2)で使用することにより、牛のアキレス腱の優れた柔軟効果が得られ、また処理後の牛のアキレス腱へのなじみ性も高く、結果として水分活性値を低く維持することができる。最終的に得られるペット用飼料が、乾燥した後や長時間空気に晒された後でも、なおも十分な柔軟性を維持することができる。また、水分活性値を低く維持することによって、細菌の増殖を抑えて、腐敗を防止できるという効果を発揮する。 By using a water-soluble treatment solution containing propylene glycol and glycerin in the dipping step (2), an excellent softening effect of the Achilles tendon of the cow is obtained, and the compatibility with the Achilles tendon of the cow after treatment is also high. As a result, the water activity value can be kept low. Even after the pet food finally obtained is dried or exposed to air for a long time, sufficient flexibility can be maintained. In addition, by maintaining the water activity value low, it is possible to suppress the growth of bacteria and prevent spoilage.
ここで、上記水溶性処理液の組成について述べる。上記水溶性処理液は、水と、プロピレングリコールと、グリセリンと、を含む。プロピレングリコール及びグリセリンの合計量は、本発明の効果を損なわない範囲で適宜決定することができるが、例えば、製品の質感で適度なやわらかさを維持するという観点から、上記水溶性処理液の15体積%〜25体積%であるのが好ましい。 Here, the composition of the water-soluble treatment liquid will be described. The water-soluble treatment liquid contains water, propylene glycol, and glycerin. The total amount of propylene glycol and glycerin can be appropriately determined within a range not impairing the effects of the present invention. For example, from the viewpoint of maintaining an appropriate softness in the texture of the product, It is preferable that it is volume%-25 volume%.
更には、適度な水分活性値と十分な柔軟性を有するペット用飼料がより確実に得られ、プロピレングリコール残留値をより確実に2.0%以下の好ましい範囲に調節可能であるという観点から、上記水溶性処理液におけるプロピレングリコール及びグリセリンの体積比(プロピレングリコール:グリセリン)が1:4〜1:3であることがより好ましい(即ち、上記水溶性処理液が合計で20体積%のプロピレングリコール及びグリセリンを含む場合は、プロピレングリコールが4体積%〜5体積%で、グリセリンが16体積%〜15体積%)。
Furthermore, from the viewpoint that pet feed having an appropriate water activity value and sufficient flexibility can be obtained more reliably, and the residual value of propylene glycol can be adjusted to a preferable range of 2.0% or less more reliably. More preferably , the volume ratio of propylene glycol and glycerin (propylene glycol: glycerin) in the water-soluble treatment liquid is 1: 4 to 1: 3 (that is, the water-soluble treatment liquid is 20% by volume in total of propylene glycol). And when it contains glycerol, propylene glycol is 4 volume%-5 volume%, and glycerol is 16 volume%-15 volume%).
この漬込み工程(2)は、上記の水溶性処理液を容器に入れ、当該容器に上記洗浄工程(2)を経た牛のアキレス腱を浸漬することにより行えばよい。容器に入れる上記の水溶性処理液の量は、牛のアキレス腱の膨張度(乃至は膨潤度)を見越して、適宜調節すればよい。本発明者は、牛のアキレス腱の膨張度(乃至は膨潤度)が約10%であることを、実験により確認している。 This soaking step (2) may be performed by putting the above-mentioned water-soluble treatment liquid in a container and immersing the Achilles tendon of the cow that has undergone the above-described washing step (2) in the container. What is necessary is just to adjust suitably the quantity of said water-soluble processing liquid put into a container in anticipation of the swelling degree (or swelling degree) of a cow's Achilles tendon. The present inventor has confirmed by experiments that the degree of expansion (or degree of swelling) of the Achilles tendon in cattle is about 10%.
漬込み工程(2)の環境温度は、常温であればよいが、原料や水溶性処理液の腐敗を防ぐという観点から、例えば18℃〜20℃程度であればよい。上記の水溶性処理液の温度は、環境温度と同じであればよい。 The environmental temperature of the dipping step (2) may be room temperature, but may be, for example, about 18 ° C. to 20 ° C. from the viewpoint of preventing the raw materials and the water-soluble treatment liquid from being spoiled. The temperature of said water-soluble processing liquid should just be the same as environmental temperature.
漬込み工程(2)における漬込み時間は、原料として用いる牛のアキレス腱のサイズ、組成及び乾燥度等によって変動するが、牛のアキレス腱の柔軟性(軟度)を確認しながら調節すればよい。漬込み時間は、例えば20時間〜80時間(特に72時間)の範囲で決定すればよい。 The soaking time in the soaking step (2) varies depending on the size, composition and dryness of the Achilles tendon of the cow used as a raw material, but may be adjusted while confirming the flexibility (softness) of the Achilles tendon of the cow. What is necessary is just to determine the pickling time in the range of 20 hours-80 hours (especially 72 hours), for example.
なお、上記の水溶性処理液には、必要に応じ、本発明の効果を損なわない範囲で、各種の補助薬剤(例えば、ソルビン酸カリウム等の保存剤等)を添加してもよい。また、上記容器として、回転樽等を用い、その中で牛のアキレス腱と上記の水溶性処理液とを混合して漬込み工程(2)を行ってもよい。 In addition, you may add various adjuvant agents (For example, preservatives, such as potassium sorbate, etc.) to said water-soluble process liquid in the range which does not impair the effect of this invention as needed. Moreover, you may perform a immersing process (2) by mixing a cow's Achilles tendon and said water-soluble processing liquid in it using a rotary barrel etc. as said container.
(3)乾燥工程
次に、上記の漬込み工程(2)を経た牛のアキレス腱を乾燥させてペット用飼料を得る(乾燥工程)。
(3) Drying process Next, the Achilles tendon of the cow which passed through said picking process (2) is dried and pet food is obtained (drying process).
乾燥工程(3)の条件は、本発明の効果を損なわない範囲で適宜調節することができるが、例えば、熱風乾燥機を用いて、55℃〜60℃の範囲とすればよい。60℃を超える温度では、牛のアキレス腱が変形するおそれがある。 Although the conditions of a drying process (3) can be suitably adjusted in the range which does not impair the effect of this invention, what is necessary is just to set it as the range of 55 to 60 degreeC, for example using a hot air dryer. If the temperature exceeds 60 ° C., the Achilles tendon of the cow may be deformed.
なお、乾燥時間は、これも本発明の効果を損なわない範囲で適宜調節することができるが、環境温度や湿度の影響を受け易いファクターである。最終的に得られるペット用飼料がソフト感に優れ、カビに起因する腐敗が起こりにくいという観点から、歩留まり率が130〜150、好ましくは135〜140となるように、乾燥時間を調節するのが好ましい。 The drying time can be appropriately adjusted within a range not impairing the effects of the present invention, but is a factor that is easily influenced by environmental temperature and humidity. From the viewpoint that the pet feed finally obtained is excellent in soft feeling and is less susceptible to decay due to mold, the drying time is adjusted so that the yield rate is 130 to 150, preferably 135 to 140. preferable.
上記の3工程を経て得られる本実施形態のペット用飼料は、2.0%以下のプロピレングリコール残留値及び0.86以下の水分活性値を有すること、が好ましい。プロピレングリコール残留値及び水分活性値の制御は、上記の漬込み工程(2)で用いる水溶性処理液の組成や上記乾燥工程(3)の条件等を調節することにより、可能である。 The pet feed of this embodiment obtained through the above three steps preferably has a propylene glycol residual value of 2.0% or less and a water activity value of 0.86 or less. The residual value of propylene glycol and the water activity value can be controlled by adjusting the composition of the water-soluble treatment liquid used in the soaking step (2) and the conditions of the drying step (3).
以上、本発明のペット用飼料の製造方法の一実施形態について説明したが、本発明はこれらのみに限定されるものでない。種々の硬質部分を含む原料を用いることができ、当該原料の種類やサイズ、組成及び構造等に応じて、各工程の各条件を適宜調節すればよい。 As mentioned above, although one Embodiment of the manufacturing method of the pet feed of this invention was described, this invention is not limited only to these. A raw material including various hard portions can be used, and each condition in each step may be appropriately adjusted according to the type, size, composition, structure, and the like of the raw material.
(1)洗浄工程
原料として、中心部分の太さが1cm〜3cm程度で、長さが6cm〜9cm程度の牛のアキレス腱(乾燥済)を120本準備し、30cm×40cm×10cmの寸法のプラスチック製の笊に入れ、蛇口から水道水を流しながらブラシで洗浄した。
(1) Cleaning step As a raw material, 120 cattle Achilles tendons (dried) having a central part thickness of about 1 cm to 3 cm and a length of about 6 cm to 9 cm are prepared, and a plastic having dimensions of 30 cm × 40 cm × 10 cm It was put into a metal bowl and washed with a brush while running tap water from the tap.
(2)漬込み工程
次に、洗浄工程(2)を経た牛のアキレス腱を、プロピレングリコール及びグリセリンを含む水溶性処理液に浸漬した。このときの環境温度は20℃とし、水溶性処理液の温度は20℃であった。また、漬込み時間は72時間とした。ここで用いた水溶性処理液の組成は、下記の表1に示すとおりとした。
(2) Dipping process Next, the Achilles tendon of the cow which passed through the washing | cleaning process (2) was immersed in the water-soluble process liquid containing a propylene glycol and glycerol. The environmental temperature at this time was 20 ° C., and the temperature of the water-soluble treatment liquid was 20 ° C. The soaking time was 72 hours. The composition of the water-soluble treatment liquid used here was as shown in Table 1 below.
(3)乾燥工程
上記漬込み工程(2)を経た牛のアキレス腱を、藤木工業(株)製の無風乾燥機である藤木式魚類乾燥機(形式51−75−125)を用い、乾燥温度55℃及び乾燥時間4.2時間の条件で乾燥し、ペット用飼料1〜4を製造した。
(3) Drying process The Achilles tendon of the cow which passed through the above-mentioned picking process (2) was dried at a temperature of 55 ° C. using a Fujiki fish dryer (type 51-75-125) which is a windless dryer manufactured by Fujiki Kogyo Co., Ltd. And it dried on the conditions of drying time 4.2 hours, and manufactured the feed 1-4 for pets.
[評価試験]
(A)プロピレングリコール(PG)残留値
上記のようにして製造したペット用飼料1〜4について、ガスクロマトグラフー質量分析法という方法で、PG残留値(%)を測定した。結果を表1に示した。
[Evaluation test]
(A) Residual value of propylene glycol (PG) The PG residual value (%) was measured for the pet feeds 1 to 4 produced as described above by a method called gas chromatography mass spectrometry. The results are shown in Table 1.
(B)水分活性(AW)値
上記のようにして製造したペット用飼料1〜4について、電気抵抗式の水分活性測定器「EZ−100ST」という方法で、AW値を測定した。結果を表1に示した。
(B) Water activity (AW) value About feed 1 for pets manufactured as mentioned above, AW value was measured by the method of an electrical resistance type water activity measuring device "EZ-100ST". The results are shown in Table 1.
表1に示す結果から、プロピレングリコールとグリセリンとの配合比が、1〜6:9〜4の体積比の場合(実験番号1〜4)に、PG残留値及びAW値のいずれかが好ましい範囲のペット用飼料が得られ、2〜5:8〜5の体積比の場合(実験番号2及び3)に、PG残留値及びAW値の両方が好ましい範囲のペット用飼料が得られることがわかる。 From the results shown in Table 1, when the mixing ratio of propylene glycol and glycerin is a volume ratio of 1 to 6: 9 to 4 (experiment numbers 1 to 4), either PG residual value or AW value is preferable. When the volume ratio of 2 to 5: 8 to 5 (experiment numbers 2 and 3) is obtained, it can be seen that a pet feed having both a PG residual value and an AW value in a preferable range can be obtained. .
なお、上記実験においては、乾燥温度55℃で乾燥時間4.2時間としたが、歩留り率が環境温度に影響されるため、135〜140%の歩留り率が理想的であった。なぜなら、表2に示すように、別途のテストの結果、乾燥させて得たペット用飼料の硬さは、乾燥時間72時間の189%のものを乾燥させ、136%まで歩留り率を調整して得たペット用飼料が一番柔らかくなった。 In the above experiment, the drying temperature was 55 ° C. and the drying time was 4.2 hours. However, since the yield rate was affected by the environmental temperature, a yield rate of 135 to 140% was ideal. Because, as shown in Table 2, the hardness of the pet feed obtained by drying as a result of a separate test is 189% of the dry time of 72 hours, and the yield rate is adjusted to 136%. The pet feed obtained was the softest.
