Description
本発明は、炭酸入りゼリー飲料等の炭酸ガスを含む食品の製造に用いる包装容器、およびこの包装容器を用いた炭酸入り食品包装体の製造方法に関する。 The present invention relates to a packaging container used for producing a food containing carbon dioxide gas such as a carbonated jelly drink, and a method for producing a carbonated food package using the packaging container.
従来、ゼリーや飲料に炭酸ガスを溶け込ませることによって、炭酸感のある食品や飲料とし、特にオレンジジュースなどに炭酸ガスを溶け込ませることによって、クエン酸による酸味を抑えつつ果汁としての味覚や爽やかさに優れた飲料とすることなどが知られ、これら炭酸入りゼリーや飲料は、密封容器（金属缶またはペットボトル）に封入された形態で商品化されている。 Conventionally, by dissolving carbon dioxide in jelly and beverages, it becomes a food and beverage with a carbonic feeling, especially by dissolving carbon dioxide in orange juice etc., suppressing the acidity due to citric acid and the taste and freshness as fruit juice These carbonated jelly and beverages are commercialized in a sealed form (metal can or plastic bottle).
上記密封容器（金属缶等）入り炭酸果汁飲料の製造方法の事例として、例えばオレンジジュース等飲料液を充填装置へ送液する配管の途中にスタティックミキサー等の気液混合装置を設け、この気液混合装置により飲料中に炭酸ガスを吹き込み溶解させる方法、または調合タンク内の飲料中に炭酸ガスを直接吹き込み溶解させる方法、あるいは従来の炭酸飲料製造ラインのカーボネーターを利用して炭酸ガスを加圧溶解させる方法で炭酸入り果汁飲料を製造し、それを金属缶に充填し密封する方法がある（例えば、特許文献１参照）。 As an example of a method for producing a carbonated fruit juice beverage containing a sealed container (such as a metal can), a gas-liquid mixing device such as a static mixer is provided in the middle of a pipe for feeding beverage liquid such as orange juice to a filling device. Carbon dioxide is blown and dissolved in the beverage using a mixing device, or carbon dioxide is blown and dissolved directly into the beverage in the preparation tank, or carbon dioxide is pressurized using a carbonator on a conventional carbonated beverage production line. There is a method of producing a carbonated fruit juice beverage by a method of dissolving, filling it in a metal can and sealing it (for example, see Patent Document 1).
また、密封容器（剛性に優れる金属缶またはカップ）入り炭酸ガス含有ゼリー状飲料の製造方法の事例として、例えば易溶性寒天、キサンタンガム、ローカストビーンガム、糖類および有機酸を組合せてゼリーを作り、このゼリーを細片状に裁断し、この細片状ゼリーと、糖類と酸味料を含むシロップ液に炭酸ガスを吸収させた炭酸ガス含有シロップ液とを剛性容器（金属缶またはカップ）に充填し密封した後、加熱処理を施してゼリーを溶融させ、溶融したゼリーとシロップ液とを混合均一化した後冷却する製造方法がある（例えば、特許文献２参照）。 In addition, as an example of a method for producing a jelly-like beverage containing carbon dioxide gas in a sealed container (a metal can or cup having excellent rigidity), for example, a jelly is made by combining easily soluble agar, xanthan gum, locust bean gum, sugar and an organic acid. Cut the jelly into strips, fill the rigid container (metal can or cup) with the strip-like jelly and a syrup containing carbon dioxide in a syrup containing saccharides and acidulant and seal it. After that, there is a manufacturing method in which heat treatment is performed to melt the jelly, and the molten jelly and syrup liquid are mixed and homogenized and then cooled (see, for example, Patent Document 2).
また、プラスチックフィルムを主体とした積層軟包装材でなるスパウト（飲み口）付ガゼット袋内へ、予め調合・殺菌された所定の量のゼリーあるいは飲料を高温で充填し、さらにそのヘッドスペースに炭酸ガスを吹き込み、前記吹き込まれた炭酸ガスをゼリーあるいは飲料中に溶解せしめることにより、炭酸入りゼリー飲料や炭酸入り飲料を製造する方法が提案されている（例えば、特許文献３参照）。 In addition, a spout (drinking) gusset bag made of a laminated soft wrapping material mainly made of plastic film is filled with a predetermined amount of jelly or beverage prepared and sterilized at high temperature, and the headspace is carbonated. There has been proposed a method for producing a carbonated jelly beverage or a carbonated beverage by blowing gas and dissolving the blown carbon dioxide gas in a jelly or beverage (for example, see Patent Document 3).
また、炭酸ガス透過性材料で形成された包装容器に、ゼリーを充填、密封し、この包装容器を一定数量まとめて、外袋へ収納し、この外袋に炭酸ガスを封入することで、前記包装容器中に充填されたゼリーに炭酸ガスを溶解させる、ゼリーの製造方法が提案されている（例えば、特許文献４参照）。 Further, the packaging container formed of a carbon dioxide gas permeable material is filled and sealed with jelly, and a certain number of the packaging containers are collected and stored in an outer bag, and carbon dioxide gas is sealed in the outer bag, There has been proposed a jelly manufacturing method in which carbon dioxide gas is dissolved in jelly filled in a packaging container (see, for example, Patent Document 4).
前記特許文献１，２に於ける炭酸入りゼリー飲料や炭酸入り飲料の製造方法では、いずれの場合でも飲料に炭酸ガスを吹き込み溶解せしめるためのスタティックミキサーやカーボネーター等前処理装置とその工程を必要とし、特に炭酸入りゼリー状飲料の製造では、易溶性寒天、キサンタンガム等でなるゼリーを細片状に裁断すること、さらに炭酸ガスを溶解せしめるシロップ液の調合、それらの混合溶解等炭酸入りゼリー状飲料の製造に多くの工程を要しコスト的にも問題のあるものであった。 In the methods for producing carbonated jelly beverages and carbonated beverages in Patent Documents 1 and 2, a pre-treatment device such as a static mixer or carbonator for blowing and dissolving carbon dioxide into the beverage and the process thereof are required in any case. In particular, in the production of carbonated jelly-like beverages, cutting jelly made of easily soluble agar, xanthan gum, etc., further preparing a syrup solution that dissolves carbon dioxide gas, mixing and dissolving them, etc. Many processes were required to produce beverages, which was problematic in terms of cost.
また、前記特許文献３に於ける炭酸入りゼリー飲料や炭酸入り飲料の製造方法では、炭酸ガスを、一定容量の包装容器中のヘッドスペースに吹き込んで使用するため、ゼリー飲料や飲料の量に対してゼリー飲料や炭酸ガスの量をバランスよく充填することが難しいものとなっていた。また、前記特許文献４における炭酸入りゼリーの製造方法では、炭酸ガス透過性材料で形成された包装容器に、ゼリーを充填、密封し、この包装容器を一定数量まとめて、外袋へ収納しているので、外袋を開封すると、外袋中の炭酸ガスだけでなく、ゼリーに溶け込んだ炭酸ガスも包装容器を通して外部へ放出されてしまうおそれがあった。 Moreover, in the manufacturing method of the carbonated jelly drink and carbonated drink in the said patent document 3, since carbon dioxide gas is blown into the head space in a fixed capacity | capacitance packaging container, it is with respect to the quantity of a jelly drink or a drink. Therefore, it has been difficult to balance the amount of jelly drink and carbon dioxide gas. Further, in the method for producing a carbonated jelly in Patent Document 4, the packaging container formed of a carbon dioxide permeable material is filled with jelly, sealed, and a certain number of packaging containers are collected and stored in an outer bag. Therefore, when the outer bag is opened, not only carbon dioxide in the outer bag but also carbon dioxide dissolved in the jelly may be released to the outside through the packaging container.
本発明は、かかる従来技術の問題点を解決するものであり、その課題とするところは、所定容量の食品と所定容量の炭酸ガス収納が可能な包装容器を提供し、併せて所定量の炭酸ガスを溶け込ませた食品を製造可能な食品の製造方法を提供することにある。なお、以下は食品としてゼリー、フルーツ、豆腐、ヨーグルトなどの炭酸溶解性のある食品が含まれる。 The present invention solves the problems of the prior art, and an object of the present invention is to provide a packaging container capable of storing a predetermined volume of food and a predetermined volume of carbon dioxide gas, and also a predetermined amount of carbon dioxide.

納部とに区分けされているので、前記食品収納部に飲料を充填し、かつ、前記炭酸ガス収納部に炭酸ガスを充填し、一定時間保存するだけで、炭酸ガス入り食品包装体を製造することができる。
That is, according to the invention according to the claim 1, the outer container is formed with carbon dioxide gas impermeable material, the outer container, the inner container formed with carbon dioxide gas permeable material, food storage unit and carbonate Since it is divided into a gas storage part, the food storage part is filled with beverages, and the carbon dioxide storage part is filled with carbon dioxide and stored for a certain period of time to produce a food package containing carbon dioxide. can do.
これは、この構成により食品収納部と炭酸ガス収納部の炭酸ガス濃度の濃度勾配により、炭酸ガス透過性材料で形成された内容器を炭酸ガスが徐々に透過し、平衡状態にしようとする作用を発生させ、炭酸ガス濃度の低い濃度の食品収納部に移動した炭酸ガスが食品の水分等に溶け込み、食品に炭酸感をもたらすことができる。 This is because the carbon dioxide gas gradually permeates through the inner container formed of the carbon dioxide permeable material due to the concentration gradient of the carbon dioxide concentration in the food storage portion and the carbon dioxide storage portion by this configuration, and the action is to achieve an equilibrium state. The carbon dioxide gas that has moved to the food storage unit having a low carbon dioxide gas concentration dissolves in the water content of the food and can give a sense of carbonation to the food.

Considering environmental issues, it can be used with great convenience in handling, such as portability and no breakage.
上記請求項３に係る発明によれば、前記食品収納部に飲料を充填密封し、かつ、前記ガス収納部にガスを充填密封後、保存することにより、事前の内容物の混合・調合作業等が不要であり、充填工程が単純化される。また、これにより混合・調合のための装置も不要であり、コスト的に有利である。またさらに、飲料、炭酸ガスをそれぞれ個別に充填するため、包装容器への充填量の制御が容易であり、飲料と炭酸ガスの配合割合を容易に調整できるという利点もある。 According to the third aspect of the present invention, the food storage unit is filled and sealed with a beverage, and the gas storage unit is filled and sealed with gas, and then stored, so that the contents can be mixed and prepared in advance. Is not required, and the filling process is simplified. In addition, this eliminates the need for an apparatus for mixing and blending, which is advantageous in terms of cost. Furthermore, since the beverage and the carbon dioxide gas are individually filled, it is easy to control the filling amount into the packaging container, and there is an advantage that the blending ratio of the beverage and the carbon dioxide gas can be easily adjusted.
また、上記請求項５に係る発明によれば、炭酸ガスの量を、充填される食品の水分量に対し、その３０〜８００容量％の範囲とし、前記炭酸ガスの量と食品の量の合計が包装容器の内容量に略等しい値とすることによって、快適な炭酸感のある包装容器に詰められた炭酸入り食品と包装容器とからなる食品包装体の製造方法とすることができる。 According to the invention of claim 5 , the amount of carbon dioxide is within the range of 30 to 800% by volume with respect to the amount of water in the filled food, and the total of the amount of carbon dioxide and the amount of food. By making the value approximately equal to the content of the packaging container, it is possible to provide a method for producing a food package comprising a carbonated food and a packaging container packed in a packaging container having a comfortable carbonic sensation.
以下、食品が飲料である場合で実施の形態を示すが、他のゼリー、フルーツ、豆腐、ヨーグルトなどの食品である場合を除外する意図ではない。 Hereinafter, although embodiment is shown by the case where a foodstuff is a drink, it is not the intention to exclude the case where it is foodstuffs, such as other jelly, fruit, tofu, and yogurt.
本発明の包装容器は、図１に示すように、炭酸ガス不透過性材料で形成された外容器（
１０）と、該外容器（１０）内に、炭酸ガス透過性材料で形成された内容器（２１）からなる仕切り部を設けた二重構造の包装容器（Ａ）である。この包装容器（Ａ）は、前記内容器（２１）の空間を飲料収納部（Ｂ）とし、前記外容器（１０）と内容器（２１）との空間を炭酸ガス収納部（Ｃ）として用いる。ここで、前記前記内容器（２１）の空間を炭酸ガス収納部（Ｃ）とし、前記外容器（１０）と内容器（２１）との空間を飲料収納部（Ｂ）としてもよい。また、前記飲料収納部（Ｂ）と炭酸ガス収納部（Ｃ）のそれぞれの容量は、例えば、飲料に吸収させる炭酸ガスの割合に応じて適宜変化させればよい。飲料に炭酸ガスを多く吸収させる場合は、前記飲料収納部（Ｂ）の容量に対して、炭酸ガス収納部（Ｃ）の容量の割合が大きくなるように、外容器（１０）の容量に対する内容器（２１）の容量を決めればよい。
As shown in FIG. 1, the packaging container of the present invention is an outer container made of a carbon dioxide impermeable material (
10) and a double-structured packaging container (A) in which a partition portion made of an inner container (21) formed of a carbon dioxide permeable material is provided in the outer container (10). This packaging container (A) uses the space of the said inner container (21) as a drink storage part (B), and uses the space of the said outer container (10) and an inner container (21) as a carbon dioxide storage part (C). . Here, the space of the inner container (21) may be the carbon dioxide storage part (C), and the space between the outer container (10) and the inner container (21) may be the beverage storage part (B). Moreover, what is necessary is just to change suitably each capacity | capacitance of the said drink storage part (B) and a carbon dioxide storage part (C) according to the ratio of the carbon dioxide absorbed by a drink, for example. When the beverage absorbs a large amount of carbon dioxide, the content of the capacity of the outer container (10) so that the ratio of the capacity of the carbon dioxide storage (C) to the capacity of the beverage storage (B) increases. The capacity of the vessel (21) may be determined.
前記容器は、硬質または半硬質材料で形成されているが、図２に示すように、前記外容器（１０）および内容器（２１）は、柔軟な袋状容器であってもよいことはいうまでもない。 The container is formed of a hard or semi-rigid material, but as shown in FIG. 2, the outer container (10) and the inner container (21) may be flexible bag-shaped containers. Not too long.
ここで、仕切り部を構成する代表的な炭酸ガス透過性材料としては、ポリプロピレンが、外容器（１０）を構成する代表的な炭酸ガス不透過性材料としては、アルミニウム箔を含む積層材料が用いられる。 Here, as a typical carbon dioxide gas permeable material constituting the partition portion, polypropylene is used, and as a typical carbon dioxide gas impermeable material constituting the outer container (10), a laminated material including an aluminum foil is used. It is done.
なお、前記炭酸ガス透過性材料としては、ポリプロピレンに限らず、他の炭酸ガス透過性材料、例えば、ポリエチレン単体やポリエチレンとの複合材料、その他の単体や複合材料であってもよい。また、炭酸ガス不透過性材料としては、アルミニウム箔を含む積層材料に限らず、プラスチックフィルムに金属、または金属酸化物の蒸着層を設けた蒸着フィルムを含む積層材料、エチレン−ビニルアルコール共重合体、ポリ塩化ビニリデン等のバリア樹脂層を設けた積層構成であってもよい。 The carbon dioxide permeable material is not limited to polypropylene, but may be other carbon dioxide permeable materials, for example, polyethylene alone, a composite material with polyethylene, or other simple substances or composite materials. Further, the carbon dioxide impermeable material is not limited to a laminated material including an aluminum foil, but a laminated material including a vapor-deposited film in which a metal or metal oxide vapor-deposited layer is provided on a plastic film, an ethylene-vinyl alcohol copolymer. Alternatively, a laminated structure in which a barrier resin layer such as polyvinylidene chloride is provided may be used.
次に、前記包装容器を用いた、炭酸ガス入り飲料包装体の製造方法について説明する。図３（ａ）に示すように、図１に示した内容器（２１）からなる飲料収納部（Ｂ）に加熱された飲料（Ｄ）を充填し、炭酸ガス不透過性材料からなる蓋材（２０）により密封する。 Next, the manufacturing method of the drink packaging body containing a carbon dioxide gas using the said packaging container is demonstrated. As shown in FIG. 3 (a), the beverage container (B) comprising the inner container (21) shown in FIG. 1 is filled with the heated beverage (D) and is made of a carbon dioxide impermeable material. Seal with (20).
次に、同図（ｂ）に示すように、炭酸ガス雰囲気に外容器（１０）を載置し、前記飲料を充填、密封した内容器（２１）を、前記外容器（１０）内に挿入し、内容器（２１）との間の炭酸ガス収納部（Ｃ）にガス（Ｅ）を充填した状態で、外容器（１０）と内容器（２１）を一体化し、密封する。 Next, as shown in FIG. 4B, the outer container (10) is placed in a carbon dioxide atmosphere, and the inner container (21) filled and sealed with the beverage is inserted into the outer container (10). Then, the outer container (10) and the inner container (21) are integrated and sealed in a state where the carbon dioxide gas storage part (C) between the inner container (21) is filled with the gas (E).
ここで、同図（ｃ）に示すように、飲料は、加熱された状態で充填、密封され、その後、常温、または低温状態で保存する。このように、飲料を充填、密封後、常温、または低温状態で保存されると、飲料収納部（Ｂ）と炭酸ガス収納部（Ｃ）の炭酸ガス濃度の差（濃度勾配）により、炭酸ガス収納部（Ｃ）に充填された炭酸ガス（Ｅ）が内容器（２１）を通して、飲料収納部（Ｂ）内の飲料（Ｄ）に溶け込んで、炭酸ガス入り飲料包装体（Ｆ）が製造される。 Here, as shown in FIG. 3C, the beverage is filled and sealed in a heated state, and then stored at a normal temperature or a low temperature. Thus, after filling and sealing a beverage, when stored at room temperature or low temperature, carbon dioxide gas is caused by the difference (concentration gradient) of the carbon dioxide concentration between the beverage storage portion (B) and the carbon dioxide storage portion (C). Carbon dioxide gas (E) filled in the storage part (C) is melted into the beverage (D) in the beverage storage part (B) through the inner container (21), and the beverage package (F) containing carbon dioxide gas is manufactured. The
ここで、内容器を剛性（保形性）のある容器（例えば射出成形した樹脂製容器）とした場合、高温で充填された内容物が冷却されることにより、密封された内容器が減圧状態となるので、炭酸ガスの内容器（２１）内への移動が、炭酸ガスの濃度勾配のみの移動による場合に比べ、より速やかに行われる。 Here, when the inner container is a rigid (shape-retaining) container (for example, an injection-molded resin container), the sealed inner container is decompressed by cooling the contents filled at a high temperature. Therefore, the movement of the carbon dioxide gas into the inner container (21) is performed more quickly than in the case of the movement of only the concentration gradient of the carbon dioxide gas.
また、図４（ａ）に示すように、図２に示した外容器（１０）と内容器（２１）との上部及び下部を密封し、炭酸ガス収納部（Ｃ）を形成する。 Further, as shown in FIG. 4A, the upper and lower portions of the outer container (10) and the inner container (21) shown in FIG. 2 are sealed to form a carbon dioxide storage part (C).
次に、同図（ｂ）に示すように、前記内容器（２１）内に、飲料（Ｄ）を充填、密封し、内容器（２１）の上部を密封する。 Next, as shown in FIG. 5B, the inner container (21) is filled with a beverage (D) and sealed, and the upper part of the inner container (21) is sealed.
ここで、同図（ｃ）に示すように、前記炭酸ガス収納部（Ｃ）に、前記外容器（１０）を通して所定量の炭酸ガス（Ｅ）を充填する。そして、飲料は、加熱された状態で充填、密封され、その後、常温、または低温状態で保存し、炭酸ガス収納部（Ｃ）に充填された炭酸ガス（Ｅ）が内容器（２１）を通して、飲料収納部（Ｂ）内の飲料（Ｄ）に溶け込んで、炭酸ガス入り飲料包装体（Ｆ）が製造される。 Here, as shown in FIG. 5C, the carbon dioxide storage part (C) is filled with a predetermined amount of carbon dioxide (E) through the outer container (10). And, the beverage is filled and sealed in a heated state, and then stored at room temperature or low temperature, and the carbon dioxide (E) filled in the carbon dioxide storage part (C) passes through the inner container (21). The beverage packaging body (F) containing carbon dioxide gas is manufactured by dissolving in the beverage (D) in the beverage storage section (B).
この時、予め、飲料収納部（Ｂ）と炭酸ガス収納部（Ｃ）の容量が決められているので、所定量の飲料、及び炭酸ガスを、それぞれ前記飲料収納部（Ｂ）と炭酸ガス収納部（Ｃ）に充填、密封するだけで、炭酸ガス入り飲料包装体（Ｆ）が容易に製造することができる。 At this time, since the capacities of the beverage storage unit (B) and the carbon dioxide storage unit (C) are determined in advance, a predetermined amount of beverage and carbon dioxide gas are stored in the beverage storage unit (B) and carbon dioxide storage, respectively. By simply filling and sealing the part (C), the beverage package (F) containing carbon dioxide can be easily produced.
ここで、前記包装容器において、飲料収納部（Ｂ）に充填する飲料に対して、炭酸ガス収納部（Ｃ）に吹き込む炭酸ガス（Ｅ）の量を、３０〜８００容量％の範囲となるように、前記飲料収納部（Ｂ）と炭酸ガス収納部（Ｃ）の容積としておくことが好ましい。 Here, in the said packaging container, the quantity of the carbon dioxide (E) which blows into a carbon dioxide storage part (C) with respect to the drink with which a drink storage part (B) is filled becomes the range of 30-800 volume%. In addition, it is preferable to set the volume of the beverage storage part (B) and the carbon dioxide storage part (C).
上記吹き込まれる炭酸ガス（Ｅ）の量を充填される飲料（Ｄ）の量に対し３０容量％に満たないと炭酸感が殆どないものとなり、その効果がなくなるので好ましくない。 If the amount of carbon dioxide gas (E) to be blown is less than 30% by volume with respect to the amount of beverage (D) to be filled, there is almost no carbonic sensation, and the effect is lost, which is not preferable.
また逆に、炭酸ガス収納部（Ｃ）に吹き込まれる炭酸ガス（Ｅ）の量を、充填される飲料（Ｄ）の量に対し８００容量％を越える、即ち炭酸ガス（Ｅ）の量が多くなると、冷蔵保存等で炭酸ガス（Ｅ）が飲料中に溶解し炭酸入り飲料とすると、炭酸ガス（Ｅ）の量が多くなり、よって容器（袋）の大きさに対し炭酸入り飲料の量が少なくなり、大気圧で一定の飲料に溶けこめる炭酸ガスの量には限界があり、商品価値にも欠けるようになり、好ましくないものである。 Conversely, the amount of carbon dioxide (E) blown into the carbon dioxide storage (C) exceeds 800% by volume with respect to the amount of beverage (D) to be filled, that is, the amount of carbon dioxide (E) is large. Then, if the carbon dioxide (E) is dissolved in the beverage by refrigerated storage or the like to make a carbonated beverage, the amount of the carbon dioxide (E) increases, and therefore the amount of the carbonated beverage relative to the size of the container (bag). There is a limit to the amount of carbon dioxide that can be dissolved in a certain beverage at atmospheric pressure, and the commercial value is lacking.
