Abstract
Description
本発明は、容器開封時における内容液の噴出を防止可能な陽圧容器詰飲料、および陽圧容器詰飲料の製造方法に関するものである。 The present invention relates to a positive-pressure container-packed beverage that can prevent ejection of a content liquid when the container is opened, and a method for producing a positive-pressure container-packed beverage.
近年、省資源化や低コスト化、また消費者の容器に対する嗜好性の広がり等から、薄肉化された陽圧容器の需要が高まっている。
このような陽圧容器に充填される飲料のうち、ミルクコーヒーやミルクティーに代表されるような起泡性を有する飲料では、消費者が開封前に行う陽圧容器の振盪、または自動販売機からの取り出し時や運搬時の振動等によって内容液が起泡している場合、容器を開封する際に内容液の泡が飛沫となって噴出し、衣服や周辺環境を汚してしまうトラブルが多数報告されている。
In recent years, demand for thin-walled positive pressure containers has increased due to resource saving, cost reduction, and spread of consumer preferences.
Among such beverages filled in a positive pressure container, for beverages having foaming properties such as milk coffee and milk tea, shaking of the positive pressure container performed by the consumer before opening or vending machine If the contents liquid is foamed due to vibrations during removal from the container or during transportation, the contents liquid foams and spouts when opening the container, causing many troubles that contaminate clothes and the surrounding environment. It has been reported.
その対策として、種々の消泡剤の添加が提案されており、このような消泡剤に関して以下の文献が知られている。特許文献１には、ポリグリセリン不飽和脂肪酸エステル、グリセリン不飽和脂肪酸エステルを含有する消泡剤が開示されており、特許文献２には、ヒドロキシプロピルセルロースを含有する消泡剤が開示されている。
さらに、特許文献３には、飲料の全重量に対して、消泡剤としてジメチルポリシロキサンが０．００２５重量％〜０．００３重量％の範囲内となるように含有された飲料が開示されており、特許文献４には、消泡用乳化剤および極性分散媒を混合した液を膜乳化装置に通して得られるエマルションである飲料用消泡剤であり、上記エマルション粒子の平均粒子径が１μｍ〜１０μｍに調整される飲料用消泡剤が添加された陽圧缶入り飲料の製造方法が開示されている。
しかしながら、上述したような消泡剤を用いても、陽圧容器開封時における内容液の噴出を十分に抑制することができなかった。
As countermeasures, addition of various antifoaming agents has been proposed, and the following documents are known regarding such antifoaming agents. Patent Document 1 discloses an antifoaming agent containing polyglycerin unsaturated fatty acid ester and glycerin unsaturated fatty acid ester, and Patent Document 2 discloses an antifoaming agent containing hydroxypropylcellulose. .
Furthermore, Patent Document 3 discloses a beverage containing dimethylpolysiloxane as an antifoaming agent in a range of 0.0025 wt% to 0.003 wt% with respect to the total weight of the beverage. Patent Document 4 discloses an antifoaming agent for beverages, which is an emulsion obtained by passing a liquid obtained by mixing an antifoaming emulsifier and a polar dispersion medium through a membrane emulsifying device, and the average particle size of the emulsion particles is from 1 μm to A method for producing a positive pressure can beverage containing a defoamer for beverages adjusted to 10 μm is disclosed.
However, even when the antifoaming agent as described above is used, the ejection of the content liquid at the time of opening the positive pressure container cannot be sufficiently suppressed.
本発明は、上記実情に鑑みてなされたものであり、容器開封時における内容液の噴出を防止可能な陽圧容器詰飲料を得ることができる陽圧容器詰飲料の製造方法、および陽圧容器詰飲料を提供することを主目的とする。 The present invention has been made in view of the above circumstances, and a method for producing a positive-pressure container-packed beverage capable of obtaining a positive-pressure container-packed beverage capable of preventing ejection of the content liquid when the container is opened, and a positive-pressure container The main purpose is to provide a stuffed beverage.
一般に陽圧容器詰飲料に用いられる飲料が、沈殿や浮遊物を生じる可能性を有する成分を含有する場合、沈殿や浮遊物の発生を防止するといった品質保持の観点から、飲料内に含有される成分の分散、均質化を図ることが必要となる。そのため、このような飲料では、高圧ホモジナイザー処理が施される。 In general, when a beverage used in a positive pressure container-packed beverage contains a component that has the possibility of causing precipitation or suspension, it is contained in the beverage from the viewpoint of maintaining quality such as prevention of precipitation or suspension. It is necessary to disperse and homogenize the components. For this reason, such a beverage is subjected to a high-pressure homogenizer treatment.
このような高圧ホモジナイザー処理が施された飲料は、起泡性を有する場合が多く、陽圧容器詰飲料とされる場合には、ジメチルポリシロキサン等のシリコーン系消泡剤が添加され、内容液の噴出を防止する方策が採られていた。しかしながら、上述した通り、このような方策を採った場合でも、十分な消泡性が得られない場合があるといった問題があった。
本発明者等は、このような問題を鋭意検討した結果、上記ジメチルポリシロキサン等のシリコーン系消泡剤は飲料表面に存在することにより、消泡性を発揮するものであるが、上述したような高圧ホモジナイザー処理が施されることにより、上記ジメチルポリシロキサン等のシリコーン系消泡剤自体も飲料内に均質に分散されてしまい、結果的に消泡効果を十分に発揮することができない状態になっている点を見出し、本発明を完成させるに至ったものである。
Beverages that have been subjected to such high-pressure homogenizer treatment often have foaming properties, and when they are made into positive-pressure container-packed beverages, a silicone-based antifoaming agent such as dimethylpolysiloxane is added to the content liquid. Measures were taken to prevent eruption. However, as described above, there is a problem that even when such a measure is taken, sufficient defoaming property may not be obtained.
As a result of intensive studies on such problems, the present inventors have demonstrated that the silicone antifoaming agent such as dimethylpolysiloxane exhibits antifoaming properties when present on the beverage surface. By applying a high pressure homogenizer treatment, the silicone antifoaming agent such as dimethylpolysiloxane itself is uniformly dispersed in the beverage, and as a result, the antifoaming effect cannot be sufficiently exhibited. The present invention has been found and the present invention has been completed.

以下、これらの発明について順に説明する。
The present invention relates to a method for producing a positive-pressure container-packed beverage and a positive-pressure container-packed beverage.
Hereinafter, these inventions will be described in order.
Ａ．陽圧容器詰飲料の製造方法
本発明の陽圧容器詰飲料の製造方法は、ジメチルポリシロキサンを含有する内容液を有する陽圧容器詰飲料の製造方法であって、５ＭＰａ以上２０ＭＰａ未満の範囲内で高圧ホモジナイザー処理を施す工程（以下、高圧ホモジナイザー処理工程として説明する場合がある。）を有することを特徴とする方法である。
A. Method for producing positive-pressure container-packed beverage The method for producing a positive-pressure container-packed beverage of the present invention is a method for producing a positive-pressure container-packed beverage having a content liquid containing dimethylpolysiloxane, and is within the range of 5 MPa or more and less than 20 MPa. And a step of performing a high-pressure homogenizer treatment (hereinafter, may be described as a high-pressure homogenizer treatment step).
本発明によれば、高圧ホモジナイザー処理工程を有する、すなわち上記範囲内の処理圧力で高圧ホモジナイザー処理を行うことにより、高圧ホモジナイザー処理工程を施してもジメチルポリシロキサンの消泡効果を発揮させることができる。これにより、容器開封時における内容液の噴出を防止することが可能な陽圧容器詰飲料を製造可能となる。また、内容液における沈殿および浮遊物の発生を抑制し、品質を維持することが可能な陽圧容器詰飲料とすることができる。 According to the present invention, the anti-foaming effect of dimethylpolysiloxane can be exhibited even if the high-pressure homogenizer treatment step is performed by performing the high-pressure homogenizer treatment step, that is, by performing the high-pressure homogenizer treatment at a treatment pressure within the above range. . This makes it possible to produce a positive pressure container-packed beverage that can prevent the content liquid from being ejected when the container is opened. Moreover, it can be set as the positive-pressure container-packed drink which can suppress generation | occurrence | production of the precipitation and suspended | floating matter in a content liquid, and can maintain quality.
（１）高圧ホモジナイザー処理工程
まず、本発明における高圧ホモジナイザー処理工程について説明する。本発明に用いられる高圧ホモジナイザー処理工程は、５ＭＰａ以上２０ＭＰａ未満の範囲内で高圧ホモジナイザー処理を施す工程である。
ここで、高圧ホモジナイザー処理とは、高圧ホモジナイザーと呼ばれる装置を用いて、内容液に含有される成分に対して、高圧に加圧してスリット（隙間）を通過させる際のせん断力により、内容液に含有される成分の粒子径を小さく粉砕し、内容液中に分散および均質化させる処理をいう。
(1) High-pressure homogenizer treatment step First, the high-pressure homogenizer treatment step in the present invention will be described. The high-pressure homogenizer treatment step used in the present invention is a step of performing a high-pressure homogenizer treatment within a range of 5 MPa or more and less than 20 MPa.
Here, the high-pressure homogenizer treatment uses a device called a high-pressure homogenizer to compress the components contained in the content liquid by applying a high pressure and shearing force when passing through the slit (gap). A process in which the particle size of the contained component is pulverized to be dispersed and homogenized in the content liquid.
本工程における高圧ホモジナイザー処理時の処理圧力としては、上述したように５ＭＰａ以上２０ＭＰａ未満の範囲内である。中でも、５ＭＰａ〜１７ＭＰａの範囲内であることがより好ましく、５ＭＰａ〜１５ＭＰａの範囲内であることが特に好ましい。上記処理圧力が上記範囲に満たない場合、沈殿や浮遊物の発生、また経時的な増加により、品質を担保することが困難となる可能性を有するからである。また一方、上記処理圧力が上記範囲を超える場合、ジメチルポリシロキサンの消泡効果が損なわれる可能性を有するからである。 The treatment pressure during the high-pressure homogenizer treatment in this step is in the range of 5 MPa or more and less than 20 MPa as described above. Especially, it is more preferable to be in the range of 5 MPa to 17 MPa, and it is particularly preferable to be in the range of 5 MPa to 15 MPa. This is because, when the processing pressure is less than the above range, it may be difficult to ensure the quality due to the generation of precipitates and suspended matters and the increase over time. On the other hand, if the treatment pressure exceeds the above range, the defoaming effect of dimethylpolysiloxane may be impaired.
本工程における高圧ホモジナイザー処理時の処理温度としては、内容液に含有される成分が効果的に分散され、均質化される程度であれば特に限定されるものではなく、通常、１５℃〜８０℃の範囲内であることが好ましく、５０℃〜７０℃の範囲内であることがより好ましい。 The treatment temperature during the high-pressure homogenizer treatment in this step is not particularly limited as long as the components contained in the content liquid are effectively dispersed and homogenized, and are usually 15 ° C to 80 ° C. It is preferable that it is in the range of 50 ° C to 70 ° C.
本工程における高圧ホモジナイザー処理の処理回数としては、内容液を均質化できる程度であれば特に限定されるものではないが、処理回数が増えるにしたがってジメチルポリシロキサンの消泡効果が低減することから、２回以下であることが好ましく、１回であることがより好ましい。 The number of times of high-pressure homogenizer treatment in this step is not particularly limited as long as the content liquid can be homogenized, but the defoaming effect of dimethylpolysiloxane decreases as the number of treatments increases. It is preferably 2 times or less, more preferably 1 time.
（２）その他の工程
本発明は、少なくとも高圧ホモジナイザー処理工程を有するものであれば特に限定されるものではなく、他の工程を有するものであっても良い。
例えば、上記高圧ホモジナイザー処理工程を行う前に、ジメチルポリシロキサン添加工程が行われる。なお、上記高圧ホモジナイザー処理工程後にジメチルポリシロキサン添加工程を行うことにより、その消泡効果を低減させない方法も考えられるが、既存の飲料工場設備では対応が大変難しく、また導入するには多額の設備改良費用を要することから、現実的に非常に困難であるとされている。
またその他の工程としては、本発明によって製造される陽圧容器詰飲料の種類等に応じて適宜設定されるものである。
(2) Other Steps The present invention is not particularly limited as long as it has at least a high-pressure homogenizer treatment step, and may have other steps.
For example, a dimethylpolysiloxane addition step is performed before the high-pressure homogenizer treatment step. In addition, a method that does not reduce the defoaming effect by performing the dimethylpolysiloxane addition step after the high-pressure homogenizer treatment step is also conceivable, but it is very difficult to cope with existing beverage factory facilities, and a large amount of equipment to introduce Since improvement costs are required, it is considered extremely difficult in practice.
Moreover, as another process, it sets suitably according to the kind etc. of the positive pressure container-packed drink manufactured by this invention.
（３）陽圧容器詰飲料
次に、本発明によって製造される陽圧容器詰飲料について説明する。本発明によって製造される陽圧容器詰飲料は、ジメチルポリシロキサンを含有する内容液を有するものである。
(3) Positive pressure container-packed drink Next, the positive pressure container-packed drink manufactured by this invention is demonstrated. The positive-pressure container-packed beverage produced by the present invention has a content liquid containing dimethylpolysiloxane.
本発明によって製造される陽圧容器詰飲料における内容液は、ジメチルポリシロキサンを含有するものであれば特に限定されるものではない。
このような内容液については、後述する「Ｂ．陽圧容器詰飲料」と同様とすることができるため、ここでの説明は省略する。
The content liquid in the positive-pressure container-packed drink manufactured by this invention will not be specifically limited if dimethylpolysiloxane is contained.
Since such a content liquid can be the same as “B. Positive pressure container-packed beverage” described later, description thereof is omitted here.
また本発明によって製造される陽圧容器詰飲料に用いられる陽圧容器は、上述した内容液を充填できるものであれば特に限定されるものではなく、例えば、後述する「Ｂ．陽圧容器詰飲料」の項に記載するものを好適に用いることができる。 Moreover, the positive pressure container used for the positive pressure container-packed drink manufactured by this invention will not be specifically limited if it can be filled with the content liquid mentioned above, For example, "B. What is described in the section of “Beverage” can be preferably used.
Ｂ．陽圧容器詰飲料
次に、本発明の陽圧容器詰飲料について説明する。本発明の陽圧容器詰飲料は、ジメチルポリシロキサンを含有し、高圧ホモジナイザー処理を必要とする内容液と、上記内容液を充填する陽圧容器と、を有する陽圧容器詰飲料であって、上記内容液の起泡量が１２．５ｍｌ未満となることを特徴とするものである。
B. Next, the positive pressure container-packed beverage of the present invention will be described. The positive-pressure container-packed beverage of the present invention is a positive-pressure container-packed beverage containing dimethylpolysiloxane and having a content liquid that requires a high-pressure homogenizer treatment, and a positive-pressure container filled with the content liquid, The amount of foaming of the content liquid is less than 12.5 ml.
本発明によれば、内容液にジメチルポリシロキサンを含有させることにより、消泡効果を発揮する、すなわち内容液において発生した泡を効率良く消すことができる。また、内容液の起泡量が１２．５ｍｌ未満となることから、容器開封時に内容液の泡が飛沫となって噴出することを防止することができる。
以下、内容液および陽圧容器について、各々説明する。
According to the present invention, by adding dimethylpolysiloxane to the content liquid, the defoaming effect is exhibited, that is, the bubbles generated in the content liquid can be efficiently erased. Moreover, since the amount of foaming of the content liquid is less than 12.5 ml, it is possible to prevent the bubbles of the content liquid from being ejected as droplets when the container is opened.
Hereinafter, each of the content liquid and the positive pressure container will be described.
１．内容液
本発明に用いられる内容液は、ジメチルポリシロキサンを含有し、高圧ホモジナイザー処理を必要とするものである。また、上記内容液は、起泡量が１２．５ｍｌ未満となるものである。
1. Content Liquid The content liquid used in the present invention contains dimethylpolysiloxane and requires high-pressure homogenizer treatment. The content liquid has a foaming amount of less than 12.5 ml.
（１）ジメチルポリシロキサン
本発明における内容液は、ジメチルポリシロキサンを含有するものである。
ここで、本発明に用いられるジメチルポリシロキサンは、食品衛生法において食品添加物として認定される消泡剤であり、内容液に含有されることにより、陽圧容器の振盪や運搬時等の振動によって発生した内容液の泡を消すことが可能となる。
(1) Dimethylpolysiloxane The content liquid in the present invention contains dimethylpolysiloxane.
Here, the dimethylpolysiloxane used in the present invention is an antifoaming agent certified as a food additive in the Food Sanitation Law, and when contained in the content liquid, it vibrates during shaking or transportation of a positive pressure container. It becomes possible to eliminate the bubbles of the content liquid generated by the above.
上記ジメチルポリシロキサンの含有量としては、内容液全量に対して、０．０００５重量％〜０．００５重量％の範囲内であることが好ましく、中でも０．００１５重量％〜０．００４重量％の範囲内であることが好ましい。
上記含有量が上記範囲に満たない場合、ジメチルポリシロキサンが十分な消泡効果を発揮することができない可能性を有するからである。また一方、上記含有量が上記範囲を超える場合、消泡効果の向上がほとんど見られず、さらに極僅かの油様の浮遊物が発生する恐れを有するからである。なお、食品衛生法によりジメチルポリシロキサンの含有量の上限は０．００５重量％と規定されている。
The content of the dimethylpolysiloxane is preferably in the range of 0.0005 wt% to 0.005 wt% with respect to the total amount of the content liquid, and more preferably 0.0015 wt% to 0.004 wt%. It is preferable to be within the range.
This is because, when the content is less than the above range, dimethylpolysiloxane may not be able to exhibit a sufficient defoaming effect. On the other hand, when the content exceeds the above range, almost no improvement in the defoaming effect is observed, and there is a possibility that a very slight oil-like suspended matter may be generated. According to the Food Sanitation Law, the upper limit of the content of dimethylpolysiloxane is defined as 0.005% by weight.
（２）起泡量
本発明に用いられる内容液は、起泡量が１２．５ｍｌ未満となるものである。また、本発明に用いられる内容液は、さらに１１．５ｍｌ未満となることがより好ましい。
上記起泡量が上記範囲を超える場合、容器開封時において内容液が噴出する量（以下、噴出し量と称して説明する場合がある。）が増加し、衣服や周辺環境を汚す可能性を有するからである。
なお、起泡量は、後述する実施例に記載の測定方法により得ることができる。
(2) Foaming amount The content liquid used in the present invention has a foaming amount of less than 12.5 ml. Further, the content liquid used in the present invention is more preferably less than 11.5 ml.
When the amount of foaming exceeds the above range, the amount of content liquid ejected at the time of opening the container (hereinafter sometimes referred to as the amount of ejection) increases, and the possibility of soiling clothes and the surrounding environment is increased. It is because it has.
In addition, the amount of foaming can be obtained by the measuring method described in Examples described later.
ここで、本発明における噴出し量とは、上記起泡量の増加に伴い、増加する傾向を示すものである。また、上記噴出し量としては、容器開封に際して、消費者の衣服や周辺環境等を汚さない程度であれば特に限定されるものではないが、通常、０．３０ｇ未満であることが好ましく、０．１５ｇ未満であることが特に好ましい。上記噴出し量が上記範囲を超える場合、容器開封時に内容液の泡が飛沫となって噴出するからである。これにより、衣服や周辺環境等を汚す可能性が高くなる。 Here, the ejection amount in the present invention indicates a tendency to increase as the amount of foaming increases. Further, the amount of ejection is not particularly limited as long as it does not contaminate the clothes or surrounding environment of the consumer when the container is opened, but it is usually preferably less than 0.30 g. Particularly preferred is less than .15 g. This is because when the amount of ejection exceeds the above range, bubbles of the content liquid are ejected as droplets when the container is opened. This increases the possibility of soiling clothes and the surrounding environment.
（３）内容液
本発明における内容液は、高圧ホモジナイザー処理を必要とするものである。
なお、高圧ホモジナイザー処理については、上記「Ａ．陽圧容器詰飲料の製造方法」の項に記載したものと同様とすることができるため、ここでの説明は省略する。
(3) Contents liquid The contents liquid in this invention requires a high pressure homogenizer process.
The high-pressure homogenizer treatment can be the same as that described in the above-mentioned section “A. Method for producing positive-pressure container-packed beverage”, and will not be described here.
高圧ホモジナイザー処理を必要とする内容液としては、例えば、乳成分が配合された液等の起泡性を有する液、泡の持続性を有する液等を挙げることができる。具体的には、脂肪分の少ないミルク入りコーヒー、ブラックコーヒー等のコーヒー飲料、ミルクティー、ココア、ミルク入り抹茶等を挙げることができる。 Examples of content liquids that require high-pressure homogenizer treatment include liquids having foaming properties such as liquids containing milk components, liquids having foam persistence, and the like. Specific examples include coffee drinks such as milk containing less fat, coffee drinks such as black coffee, milk tea, cocoa, and milk-matched green tea.
このような内容液としては、起泡性を有する液、または泡の持続性を有する液であれば特に限定されるものではないが、中でもコーヒー飲料であることが好ましい。起泡性および泡の持続性に優れることから、本発明の効果を発揮しやすく、また、他の飲料に比べて需要が高いからである。 Such a content liquid is not particularly limited as long as it is a liquid having foamability or a liquid having foam persistence, but among them, a coffee beverage is preferable. It is because it is easy to exhibit the effect of this invention from being excellent in foaming property and foam persistence, and is because a demand is high compared with other drinks.
上述したようなコーヒー飲料としては、一般的なコーヒー液を含有するものであれば特に限定されるものではなく、例えば、コーヒー豆の抽出液、コーヒー抽出液を濃縮したコーヒーエキス、コーヒー抽出液を乾燥したインスタントコーヒー等が水や温水等で適量に調整された溶液を含有するものが挙げられる。 The coffee beverage as described above is not particularly limited as long as it contains a general coffee liquid. For example, a coffee bean extract, a coffee extract obtained by concentrating a coffee extract, and a coffee extract are used. Examples include dried instant coffee containing a solution adjusted to an appropriate amount with water or warm water.
さらに上述したようなコーヒー飲料としては、中でも、ブリックス値１．０の透過率が４０％以上となるコーヒー液を含有するものであることが好ましい。ジメチルポリシロキサンが内容液内に含有される他の成分に吸着されること等による消泡効果の低減を防止できるからである。
ここで、上記ブリックス値とは、コーヒー抽出液の可溶性固形分の濃度を示す値であり、公知の測定方法で測定できる。なお、上記透過率は、波長６６０ｎｍの光を用いて測定した、光路長１０ｍｍの透過率である。
Furthermore, the coffee beverage as described above preferably contains a coffee liquid having a transmittance of a Brix value of 1.0 of 40% or more. This is because it is possible to prevent the defoaming effect from being reduced due to adsorption of dimethylpolysiloxane to other components contained in the content liquid.
Here, the Brix value is a value indicating the concentration of the soluble solid content of the coffee extract, and can be measured by a known measuring method. In addition, the said transmittance | permeability is the transmittance | permeability of 10 mm of optical path lengths measured using the light of wavelength 660nm.
上記内容液としては、上述したように、ジメチルポリシロキサンを含有し、高圧ホモジナイザー処理を必要とするものであり、起泡量が１２．５ｍｌ未満となるものであれば特に限定されるものではなく、内容液の品質向上等の観点から、添加剤を含有するものであっても良い。なお、上記添加剤としては、一般的な陽圧容器詰飲料における内容液に用いられるものであれば特に限定されるものではない。 As described above, the content liquid is not particularly limited as long as it contains dimethylpolysiloxane and requires high-pressure homogenizer treatment, and the amount of foaming is less than 12.5 ml. From the viewpoint of improving the quality of the content liquid, it may contain an additive. In addition, as said additive, if it is used for the content liquid in a general positive pressure container-packed drink, it will not specifically limit.
２．陽圧容器
次に、本発明に用いられる陽圧容器について説明する。本発明に用いられる陽圧容器は、上述した内容液を充填するものである。
ここで、上記陽圧容器としては、一般的な陽圧容器と同様に陽圧状態を形成するものであり、ヘッドスペース、すなわち、陽圧容器内の内容液が充填されていない部分に、窒素ガスや炭酸ガス等を封入して密閉することにより、容器内を陽圧状態としている。なお、上記陽圧状態とは、大気圧より高い気圧を有する状態である。
2. Positive pressure vessel Next, the positive pressure vessel used in the present invention will be described. The positive pressure vessel used in the present invention is filled with the above-described content liquid.
Here, the positive pressure vessel forms a positive pressure state in the same manner as a general positive pressure vessel, and the head space, that is, a portion not filled with the content liquid in the positive pressure vessel is filled with nitrogen. The inside of the container is in a positive pressure state by sealing with gas or carbon dioxide gas. In addition, the said positive pressure state is a state which has atmospheric pressure higher than atmospheric pressure.
上記陽圧容器としては、上述した内容液を充填することができるものであれば特に限定されるものではないが、例えば、薄肉化された２ピース陽圧缶、陽圧ボトル缶等を挙げることができる。上記２ピース陽圧缶の具体例としては、アルミニウム製２ピース陽圧缶やスチール製２ピース陽圧缶を挙げることができ、上記陽圧ボトル缶の具体的な例としては、アルミニウム製陽圧ボトル缶を挙げられる。
上記陽圧容器としては、中でも陽圧ボトル缶がより好ましい。利便性やデザイン性に優れており、需要が高いからである。また、その形状から、特に開封時に噴出する可能性が高いため、本発明の効果を発揮しやすいからである。
The positive pressure vessel is not particularly limited as long as it can be filled with the above-described content liquid. Examples thereof include a thinned two-piece positive pressure can and a positive pressure bottle can. Can do. Specific examples of the two-piece positive pressure can include an aluminum two-piece positive pressure can and a steel two-piece positive pressure can. As a specific example of the positive pressure bottle can, an aluminum positive pressure can A bottle can.
As the positive pressure container, a positive pressure bottle can is more preferable. This is because it is excellent in convenience and design, and demand is high. In addition, because of its shape, the possibility of jetting is particularly high at the time of opening, and thus the effects of the present invention are easily exhibited.
上記陽圧容器の内圧（以下、容器内圧として説明する場合がある。）としては、陽圧状態となるものであれば特に限定されるものではないが、通常、０．０５ＭＰａ〜０．１２ＭＰａの範囲内であることが好ましく、０．０６ＭＰａ〜０．０８ＭＰａの範囲内であることが特に好ましい。上記容器内圧が上記範囲に満たない場合、薄肉化された容器、例えば陽圧ボトル缶等では、缶胴部の張りが弱まるといった、強度維持が困難となる可能性を有するからである。また一方、上記容器内圧が上記範囲を超える場合、内容液に僅かな泡が発生し、容器開封時に飛沫となって噴出する可能性を有するからである。 The internal pressure of the positive pressure vessel (hereinafter may be described as the vessel internal pressure) is not particularly limited as long as it is in a positive pressure state, but is usually 0.05 MPa to 0.12 MPa. It is preferably within the range, and particularly preferably within the range of 0.06 MPa to 0.08 MPa. This is because when the internal pressure of the container is less than the above range, it is difficult to maintain the strength of the thinned container, such as a positive pressure bottle can, because the tension of the can body portion is weakened. On the other hand, when the internal pressure of the container exceeds the above range, a slight bubble is generated in the content liquid and there is a possibility that the liquid may be ejected as a droplet when the container is opened.
３．陽圧容器詰飲料
本発明の陽圧容器詰飲料は、少なくとも上述した内容液と、陽圧容器とを有するものであり、必要に応じて他の構成を有していても良い。このような他の構成としては、特に限定されるものではなく、陽圧容器詰飲料の種類等に応じて適宜選択されるものである。
3. Positive-pressure container-packed beverage The positive-pressure container-packed beverage of the present invention has at least the above-described content liquid and a positive-pressure container, and may have other configurations as necessary. Such other configuration is not particularly limited, and is appropriately selected according to the type of the positive pressure container-packed beverage.
本発明の陽圧容器詰飲料の製造方法としては、上述したような陽圧容器詰飲料を製造することができるものであれば特に限定されるものではなく、例えば、上記「Ａ．陽圧容器詰飲料の製造方法」の項に記載される製造方法を好適に用いることができる。 The method for producing a positive pressure container-packed beverage of the present invention is not particularly limited as long as it can produce a positive-pressure container-packed beverage as described above. For example, the above-mentioned “A. The production method described in the section “Method for producing a stuffed beverage” can be preferably used.
なお、本発明は、上記実施形態に限定されるものではない。上記実施形態は、例示であり、本発明の特許請求の範囲に記載された技術的思想と実質的に同一な構成を有し、同様な作用効果を奏するものは、いかなるものであっても本発明の技術的範囲に包含される。 The present invention is not limited to the above embodiment. The above-described embodiment is an exemplification, and the present invention has substantially the same configuration as the technical idea described in the claims of the present invention, and any device that exhibits the same function and effect is the present invention. It is included in the technical scope of the invention.
以下、実施例および比較例を挙げることにより、本発明について具体的に説明する。 Hereinafter, the present invention will be specifically described by giving examples and comparative examples.
