Description

本発明は、水素含有飲料が容器に充填され当該容器が密封されてなる容器詰水素含有飲料に関するものであり、特に、容器充填後の加熱殺菌、その後の保管においても、水素濃度の保持率の高い状態で維持し得る容器詰水素含有飲料に関するものである。また、本発明は、前記容器詰水素含有飲料の製造方法及び水素濃度保持方法にも関する。   The present invention relates to a container-packed hydrogen-containing beverage in which a hydrogen-containing beverage is filled in a container and the container is hermetically sealed. In particular, the hydrogen concentration retention rate can be maintained even in heat sterilization after container filling and subsequent storage. The present invention relates to a container-packed hydrogen-containing beverage that can be maintained in a high state. The present invention also relates to a method for producing the container-packed hydrogen-containing beverage and a method for maintaining the hydrogen concentration.

我国における飲料製品は、生活スタイルの変化や飲食に対する嗜好の多様化に応えるため、その種類は年々増加し続けている。特に、所定の容器中に封入され、そのままの状態で飲用可能な所謂RTD(Ready to Drink)形態の容器詰飲料が飲料製品全体でも主流となっている。更に、RTD形態の容器詰飲料は、紙製容器等が用いられ冷蔵保管が必要な所謂チルド製品と、缶やペットボトルといった常温で長期間の保存が可能な所謂ドライ製品とに分類されるが、ドライ製品がより大きな市場規模を有している。   The types of beverage products in our country continue to increase year by year in order to respond to changing lifestyles and diversifying tastes for eating and drinking. In particular, the so-called RTD (Ready to Drink) form of a packaged beverage that is enclosed in a predetermined container and can be drunk as it is has become the mainstream in the entire beverage product. Furthermore, RTD-type packaged beverages are classified into so-called chilled products that use paper containers and the like and need to be refrigerated, and so-called dry products that can be stored for a long period of time at room temperature, such as cans and PET bottles. Dry products have a larger market size.

ドライ製品に分類される容器詰飲料としては、ミネラルウォーター、コーヒー飲料、紅茶や緑茶といった茶系飲料、野菜果汁飲料、機能性飲料など非常に多種多様であり、一般的に数ヶ月間という長期の保存を可能とするため、容器充填後に加熱殺菌処理が行われている。
一方で、上記加熱殺菌処理によって、いずれの飲料カテゴリにおいても、高温での加熱による、風味や呈味の劣化抑制という課題を常に有していた。
Containerized beverages that are classified as dry products are very diverse, including mineral water, coffee beverages, tea-based beverages such as tea and green tea, vegetable juice beverages, and functional beverages. In order to enable storage, a heat sterilization process is performed after filling the container.
On the other hand, the above-described heat sterilization treatment always has a problem of suppressing deterioration of flavor and taste due to heating at a high temperature in any beverage category.

また、昨今の食と健康に対する意識の高まりもあって、身体に対する生理活性機能を備えた、所謂機能性飲食品に注目が集まっている。飲料製品もこの例外ではなく、昨今では、健康増進法等に定められた上記の特定保健用食品(トクホ)や、栄養機能食品の対象とは別に、一定の要件を備えることで食品への機能性表示が認められるという、新たな機能性飲料の制度にも期待が寄せられており、生理活性機能を有する可能性がある新規の成分についても鋭意研究が進められている。   In addition, with the recent increase in awareness of food and health, attention has been focused on so-called functional foods and drinks having physiologically active functions on the body. Beverage products are no exception, and nowadays, they have certain requirements apart from the above-mentioned foods for specified health use (Tokuho) defined in the Health Promotion Act and other functional foods. Expectations are also drawn for a new functional beverage system in which sex labeling is recognized, and intensive studies are also being conducted on new ingredients that may have a physiologically active function.

生理活性機能を発揮する可能性がある成分として、近年注目されている物質の一つに水素がある。水素を高濃度で水に溶解させた、所謂「水素水」は、溶存水素の身体に対する具体的な挙動や、作用メカニズムの詳細については現状不明であるものの、分子状の水素が体内の活性酸素(酸素ラジカル)を除去する効果があるとされ、これによってさまざまな健康増進作用を促進するものとして期待されている。水素を含有する水素水は、缶やパウチ形態等の容器に封入された水素水製品として広く流通している。   Hydrogen is one of the substances that have been attracting attention in recent years as a component that may exert a physiologically active function. The so-called “hydrogen water”, in which hydrogen is dissolved in water at a high concentration, is not known in detail about the specific behavior of dissolved hydrogen to the body and the details of the mechanism of action, but molecular hydrogen is the active oxygen in the body. It is said that there is an effect of removing (oxygen radical), and this is expected to promote various health promoting actions. Hydrogen water containing hydrogen is widely distributed as hydrogen water products sealed in containers such as cans and pouches.

水素水に関する先行技術として、水素以外の原料の生理活性機能に着目した飲料、例えば、茶類、果実・野菜類等からなる機能性原料を水素水に配合した水素含有飲料に係る発明が提案されている(特許文献1参照)。また、飲料用水素水の製造方法として、ガス透過膜を介して原料水に所定圧に加圧した水素を溶解させる工程と、溶解後の水素水の水素濃度を測定する工程と、水素濃度が所定範囲になるように、加圧水素の圧力を調整する工程を備えた飲料用水素含有水の製造方法が提案されている(特許文献2参照)。   As prior art relating to hydrogen water, beverages focused on physiologically active functions of raw materials other than hydrogen, for example, inventions relating to hydrogen-containing beverages in which functional raw materials composed of teas, fruits, vegetables, etc. are blended in hydrogen water have been proposed. (See Patent Document 1). In addition, as a method for producing drinking hydrogen water, a step of dissolving hydrogen pressurized to a predetermined pressure in raw water through a gas permeable membrane, a step of measuring the hydrogen concentration of dissolved hydrogen water, and a hydrogen concentration There has been proposed a method for producing hydrogen-containing water for drinking, which includes a step of adjusting the pressure of pressurized hydrogen so as to be within a predetermined range (see Patent Document 2).

水素の水への溶解度は溶解させる際に接触させる水素の圧力に比例することから、溶解度を単純に上げるためには、高圧下で溶解させればよい。しかしながら、このような水素含有飲料においては、常圧における水素の水への溶解度は極めて低い(約1.6ppm)ため、高圧下で過飽和状態に溶解させた場合であっても、容器詰の形態で長期間保管すると、容器中の水と容器との間に生じる空間部(所謂ヘッドスペース)に溶解した水素が放出され、水中の水素濃度が減少してしまうという問題があった。この問題に関し、水素水を充填した缶容器に缶蓋部を取り付ける工程において、水素水を缶体から溢水させる二次オーバーフローを生じさせ、水素水を金属缶体に満注、即ち上記ヘッドスペースを生じることなく充填するようにした水素水の充填製品の製造方法が提案されている(特許文献3参照)。また、容器のキャップの内側に突起部を有し、上記突起部の体積と、充填した水素含有液体の体積の和が、ボトル缶本体の満注量である体積と等しくなるようにすることで、ヘッドスペースを生じないようにした水素含有液体充填容器、及び当該容器を使用して、水素含有液体を充填する水素含有液体の充填方法が提案されている(特許文献4参照)。   Since the solubility of hydrogen in water is proportional to the pressure of hydrogen that is contacted when dissolved, in order to simply increase the solubility, it may be dissolved under high pressure. However, in such a hydrogen-containing beverage, the solubility of hydrogen in water at normal pressure is very low (about 1.6 ppm), so even if it is dissolved in a supersaturated state under high pressure, When stored for a long time, the hydrogen dissolved in the space (so-called head space) generated between the water in the container and the container is released, and the hydrogen concentration in the water decreases. In connection with this problem, in the step of attaching the can lid portion to the can container filled with hydrogen water, a secondary overflow that causes the hydrogen water to overflow from the can body is generated, and the hydrogen water is filled into the metal can body, that is, the head space is reduced. There has been proposed a method of manufacturing a hydrogen water filled product that is filled without being generated (see Patent Document 3). Also, by having a protrusion on the inside of the container cap, the sum of the volume of the protrusion and the volume of the hydrogen-containing liquid filled is equal to the volume that is the full amount of the bottle can body. There have been proposed a hydrogen-containing liquid filling container that does not generate a head space, and a hydrogen-containing liquid filling method that uses the container to fill the hydrogen-containing liquid (see Patent Document 4).

特許文献3及び4の方法はいずれも、水素含有飲料において水素濃度が減少する理由が、ヘッドスペースに水素が放出されてしまうことにあると考え、容器内に水素含有飲料を満注充填しヘッドスペースを生じさせないようにしたものである。   In any of the methods of Patent Documents 3 and 4, the reason why the hydrogen concentration is reduced in the hydrogen-containing beverage is that hydrogen is released into the head space, and the head is filled with the hydrogen-containing beverage in the container. It is designed not to create a space.

しかし、ボトル缶等の容器詰飲料がヘッドスペースを有しない場合、搬送時等における衝撃に弱く、開栓時に内容物(飲料)が噴出する虞があるといった容器強度的な問題が生じ、商品形態として適切でないという問題があった。
また、発明者らがヘッドスペースの体積と水素濃度の保持率(液体充填直後からの水素濃度の減少率)との関係を検証したところ、単純にヘッドスペースを小さくすれば水素濃度の保持率が向上するという関係は成立しないことが判明した。
従って、上記の容器強度についての問題を解決しつつも水素濃度の保持率を高い状態で確保するためのヘッドペースに関する最適な要件、及びこの要件を満たす容器詰水素含有飲料については、当業者においても知られていなかった。
However, when a container-packed beverage such as a bottle can does not have a head space, it is vulnerable to impact during transportation and the like, and there is a problem of container strength such that the contents (beverage) may be ejected when the bottle is opened. There was a problem that was not appropriate.
In addition, the inventors verified the relationship between the volume of the head space and the retention rate of hydrogen concentration (the decrease rate of hydrogen concentration immediately after liquid filling), and if the head space is simply reduced, the retention rate of hydrogen concentration can be reduced. It turns out that the relationship of improvement does not hold.
Therefore, for those skilled in the art, the optimum requirements for the head pace for securing the hydrogen concentration retention rate in a high state while solving the above-mentioned problems regarding the strength of the container, and the container-packed hydrogen-containing beverage that satisfies this requirement Was also not known.

本発明は、上記問題を鑑みてなされたものであって、容器強度を十分に確保しつつも、容器充填後から水素濃度が低下しにくい容器詰水素含有飲料、及びその製造方法を提供することを目的とする。   The present invention has been made in view of the above problems, and provides a container-packed hydrogen-containing beverage in which the hydrogen concentration is less likely to decrease after filling the container while sufficiently securing the container strength, and a method for producing the same. With the goal.

上記課題を達成するために本発明者らが鋭意研究した結果、封入された水素含有飲料の内容量に対するヘッドスペースの体積の割合と、ヘッドスペースの内圧とのバランスを所定範囲に調整することによって、上記課題を解決できることを見出し、本発明を完成させるに至った。   As a result of intensive studies by the present inventors in order to achieve the above-mentioned problem, by adjusting the balance between the ratio of the volume of the head space to the internal volume of the enclosed hydrogen-containing beverage and the internal pressure of the head space to a predetermined range The present inventors have found that the above problems can be solved, and have completed the present invention.

以下、本発明の実施形態について説明する。
1.容器詰水素含有飲料
(ヘッドスペース割合とヘッドスペース内圧との関係)
本発明の実施形態に係る容器詰水素含有飲料は、所定のヘッドスペースを有するように水素含有飲料が容器に封入されてなるものである。
本実施形態に係る容器詰水素含有飲料は、水素含有飲料の内容量VL(mL)と、ヘッドスペースの体積Hv(mL)と、ヘッドスペースの内圧Hp(MPa)との関係が、下記式1を満たすことを要する。
0.0020≦(Hv/VL)×Hp≦0.0070 ・・・(1)
Hereinafter, embodiments of the present invention will be described.
1. Bottled hydrogen-containing beverage (Relationship between headspace ratio and headspace internal pressure)
The container-packed hydrogen-containing beverage according to the embodiment of the present invention is obtained by enclosing a hydrogen-containing beverage in a container so as to have a predetermined head space.
In the container-packed hydrogen-containing beverage according to this embodiment, the relationship between the internal volume VL (mL) of the hydrogen-containing beverage, the volume Hv (mL) of the head space, and the internal pressure Hp (MPa) of the head space is expressed by the following formula 1. It is necessary to satisfy.
0.0020 ≦ (Hv / VL) × Hp ≦ 0.0070 (1)

ここで、ヘッドスペースの体積Hvを水素含有飲料の内容量VLで除した値Hv/VLは、水素含有飲料に対するヘッドスペースの割合と言い得るものである。
本発明者らは、容器詰水素含有飲料において、水素含有飲料に対するヘッドスペースの割合Hv/VLとヘッドスペースの内圧Hpとの関係が上記式1の要件を満たすことによって、搬送時等の耐衝撃性に優れるとともに開栓時の噴きこぼれが抑制され、かつ、経時による水素濃度の保持率が改善されることを見出した。すなわち、(Hv/VL)×Hpが0.0020〜0.0070であることにより、水素濃度の保持率を向上させると共に容器強度等を確保することができる。特に、(Hv/VL)×Hpが0.0020以上であることで、より水素濃度の保持率を高く維持しつつも、容器強度等を確保することができる。一方、(Hv/VL)×Hpが0.0070以下であると、水素濃度の保持率が特に優れたものとなる。

Here, the value Hv / VL obtained by dividing the volume Hv of the headspace by the internal volume VL of the hydrogen-containing beverage can be said to be the ratio of the headspace to the hydrogen-containing beverage.
In the case of a container-packed hydrogen-containing beverage, the inventors of the present invention have a relationship between the ratio Hv / VL of the head space to the hydrogen-containing beverage and the internal pressure Hp of the head space, so It has been found that it has excellent properties, suppresses spills when it is opened, and improves the retention of hydrogen concentration over time. That is, when (Hv / VL) × Hp is 0.0020 to 0.0070, the retention rate of hydrogen concentration can be improved and the container strength and the like can be ensured. In particular, when (Hv / VL) × Hp is 0.0020 or more, the strength of the container and the like can be ensured while maintaining a higher hydrogen concentration retention rate. On the other hand, when (Hv / VL) × Hp is 0.0070 or less, the hydrogen concentration retention rate is particularly excellent.

(Head space volume)
The volume Hv (mL) of the head space is preferably 10.0 mL to 20.0 mL, more preferably 10.0 mL to 15.0 mL in view of container strength, ejection prevention at the time of opening, and the like. . When the volume Hv of the head space is 10.0 mL or more, it is further excellent in impact resistance during transportation and the like, and spilling at the time of opening is suppressed, while the head space volume Hv is 20.0 mL or less, In addition to the effect, the retention rate of hydrogen concentration over time becomes more excellent.

ここで、水素含有飲料の内容量VLは、水素含有飲料を充填する前の空容器の質量と、充填後の容器詰水素含有飲料の質量とを測定し、その差分として得られる水素含有飲料の充填質量(g)を、比重1.00にて体積(mL)換算した値である。また、ヘッドスペース体積Hvは、開栓前の容器詰水素含有飲料の質量を測定した後、開栓して比重1.00の水を満注して合計質量を測定し、その増分であるヘッドスペース体積に相当する水の質量(g)を、比重1.00にて体積(mL)換算した値である。水素含有飲料の内容量VL及びヘッドスペース体積Hvの測定方法の詳細は、後述する実施例にて示す。
なお、水素含有飲料の内容量VL及びヘッドスペースの体積Hvは、所定の容量を備える容器を用い、また、当該容器への水素含有飲料の充填量を調整することで、所望の値に制御することができる。
Here, the internal volume VL of the hydrogen-containing beverage is obtained by measuring the mass of the empty container before filling the hydrogen-containing beverage and the mass of the container-packed hydrogen-containing beverage after filling, It is a value obtained by converting the filling mass (g) into a volume (mL) at a specific gravity of 1.00. The head space volume Hv is an increment of the head after measuring the mass of the container-containing hydrogen-containing beverage before opening, then opening and filling with water with a specific gravity of 1.00 to measure the total mass. This is a value obtained by converting the mass (g) of water corresponding to the space volume into a volume (mL) at a specific gravity of 1.00. Details of the method for measuring the internal volume VL and the head space volume Hv of the hydrogen-containing beverage will be described in the examples described later.
The internal volume VL of the hydrogen-containing beverage and the volume Hv of the head space are controlled to desired values by using a container having a predetermined capacity and adjusting the filling amount of the hydrogen-containing beverage into the container. be able to.

また、ヘッドスペースの内圧Hp(MPa)は、一般的に缶テスターと称される、真空検缶機等を使用して測定することが可能である。なお、本実施形態の容器詰水素含有飲料が、容器を密封した後にさらに加熱殺菌されるものである場合、上記ヘッドスペース内圧は、容器を密封しさらに加熱殺菌した後に測定するものとする。
Here, in this embodiment, the gas constituting the head space is, for example, nitrogen gas, and the internal pressure of the head space is obtained by dropping liquid nitrogen or the like after the beverage liquid is filled in the container. It can be adjusted by adjusting the dripping amount of liquid nitrogen when winding (sealing) after expelling air or the like from the space.
Further, the internal pressure Hp (MPa) of the head space can be measured by using a vacuum tester or the like generally called a can tester.

一方、充填時水素濃度の上限値は特に制限されないが、充填時の安全性、製造コスト等を鑑みれば、3.0ppm以下であってよく、さらには2.5ppm以下であってよい。
(Hydrogen concentration during filling)
In a container-containing hydrogen-containing beverage, since the hydrogen concentration at the time of container filling is the highest, it is common to display the hydrogen concentration at the time of filling.

More preferably, it is 0.5 ppm or more, more preferably 1.8 ppm or more, and most preferably 2.0 ppm or more. When the hydrogen concentration at the time of filling is not less than the above lower limit value, the hydrogen concentration is easily maintained at a high value even when the container-packed hydrogen-containing beverage is drunk (at the time of opening), and a favorable physiological activity due to hydrogen can be expected. Furthermore, when the filling hydrogen concentration is equal to or higher than the above lower limit value, the hydrogen concentration is not only maintained high, but also the hydrogen concentration retention rate tends to be higher than when the filling hydrogen concentration is lower. This is particularly preferable.
On the other hand, the upper limit value of the hydrogen concentration during filling is not particularly limited, but may be 3.0 ppm or less, and may be 2.5 ppm or less in view of safety during filling, production cost, and the like.

However, from the viewpoint of improving the retention rate of hydrogen concentration, at least sugar, lipid and protein are not substantially contained, and other components derived from water as a solvent (for example, minerals) It is preferable not to contain other components.

(pH)
本実施形態に係る容器詰水素含有飲料のpHは、特に制限されるものではないが、飲料が所謂ミネラルウォーターの場合は、pHは中性域を中心とした5.0〜9.5が好ましく、5.5〜9.0がより好ましく6.0〜8.5が更に望ましく、6.2〜8.0が最も好ましい。

Although the bottle-shaped container is excellent from the viewpoint of hydrogen retention and resealability, it will not return to its original shape when deformed, such as a dent, compared to a PET bottle.For example, like a PET bottle drink filled with hot packs, It is difficult to eliminate or reduce the head space from the viewpoint of impact resistance.
Therefore, if it does not depend on the knowledge of this embodiment, it is very difficult to ensure both the hydrogen retention function and the impact resistance performance.

また、容器の容量は本実施形態の要件満たす範囲であれば、特に制限されるものではないが、300〜550mLであることが好ましい。容器の容量がかかる範囲にあると、十分量の水素含有飲料が充填されても前述したヘッドスペース体積やヘッドスペース割合を確保することが容易となり、水素濃度の保持率を良好なものとすることができる。   Moreover, the capacity | capacitance of a container will not be restrict | limited especially if it is the range which satisfy | fills the requirements of this embodiment, However, It is preferable that it is 300-550 mL. When the capacity of the container is in such a range, even if a sufficient amount of hydrogen-containing beverage is filled, it becomes easy to ensure the above-mentioned head space volume and head space ratio, and the retention rate of hydrogen concentration should be good.

Such a hydrogen-containing beverage is filled in a metal can, and after a desired amount of liquid nitrogen is dropped to adjust the internal pressure of the container after sealing (and after heat sterilization), air in the headspace is expelled and then sealed (clamped). . In the case of hot pack filling, heat sterilization (post sterilization) is performed after the sealing.

(殺菌)
本実施形態に係る容器詰水素含有飲料は、加熱殺菌できる場合にあっては食品衛生法に定められた殺菌条件で製造できる。殺菌の条件は食品衛生法に定められた条件と同等の効果が得られる方法を選択すればよいが、水素濃度を可能な限り保持するという観点から、殺菌は容器封入後、容器ごと殺菌する方法が好ましい。殺菌方法としては、レトルト殺菌等があるが、容器ごと殺菌する方法であれば、高温の水を容器外部から浴びさせる方法等を選択することができる。
(Sterilization)
The container-packed hydrogen-containing beverage according to the present embodiment can be produced under the sterilization conditions defined in the Food Sanitation Law if it can be heat-sterilized. The sterilization conditions may be selected by a method that can achieve the same effect as the conditions stipulated in the Food Sanitation Law. From the viewpoint of maintaining the hydrogen concentration as much as possible, sterilization is a method of sterilizing the entire container after enclosing the container. Is preferred. As a sterilization method, there are retort sterilization and the like, but if the method is to sterilize the entire container, a method of bathing hot water from the outside of the container can be selected.

以上説明した実施形態に係る容器詰水素含有飲料は、水素含有飲料の内容量に対するヘッドスペース体積の割合Hv/VLとヘッドスペースの内圧Hpとの関係が所定の要件を満たしているため、ヘッドスペースを有しながらも水素濃度が低下しにくいものとなる。   The container-packed hydrogen-containing beverage according to the embodiment described above has a headspace because the relationship between the ratio Hv / VL of the headspace volume to the content of the hydrogen-containing beverage and the internal pressure Hp of the headspace satisfies a predetermined requirement. However, the hydrogen concentration is difficult to decrease.
