Description
【０００１】
【産業上の利用分野】
本発明は、キクが合成樹脂フイルムの袋により包装された後も、キクを適正な酸素と二酸化炭素の雰囲気下で呼吸を抑制させることにより、いわゆるＭＡ（＝Ｍｏｄｉｆｉｅｄ Ａｔｍｏｓｐｈｅｒｅ）貯蔵により鮮度保持をさせるための包装方法に関するものである。
【０００２】
【従来の技術】
キクは収穫された後も呼吸作用を持続する。このため収穫後の貯蔵、流通の間、および消費者に届くまで、キクの呼吸が活発に行われることにより、体内の養分や水分が消費され続け、品質が劣化する。呼吸は低温にすることによりある程度は抑制することが出来るが、完全ではなく、また低温貯蔵、流通は未だ完璧でないのが現状である。
キクは、葬祭用の需要が圧倒的なため周年で栽培されている。しかし、年２回の彼岸、新旧の盆、それに年末年始に需要のピークがあり、この時期は品薄になり、価格も高騰する。このため、キクの産地や花屋ではこの需要の伸びる時期の前から冷蔵庫などで低温で貯蔵し数量不足と価格の高騰に対応してきた。
また、葬儀屋では急な葬儀にも対応するため常にある程度のキクのストックを持つ必要があり、これに対しても冷蔵庫での低温による貯蔵で賄ってきた。
しかしこれら低温だけでの貯蔵では、貯蔵中に花の開花ステージが進行し、商品規格に合わなくなったり、呼吸により養分の消費が進むと、冷蔵庫から取り出した後に水に活けても、水を吸い上げる力がないと開花しないなどの問題があった。
さらに、キクの貯蔵の技術としてＣＡ（＝Ｃｏｎｔｒｏｌｅｄ Ａｔｍｏｓｐｈｅｒｅ）貯蔵も提案されている。この方法は、キクの鮮度が最も良く保たれる酸素と二酸化炭素と窒素の混合比を実験的に求め、この混合ガスをキクを貯蔵する冷蔵庫内に充填し、且つその混合比が常に保たれるようにガス濃度をモニターしながら、不足分を補充する大がかりなシステムであり、設備費や運転費が膨大で、キクが少量の場合は、採算が合わないという問題があった。
このキクに対するＣＡ貯蔵での酸素と二酸化炭素と窒素の混合比は体積比で、約２：２：９６であり、（参考文献：食品流通技術 Ｖｏｌ．２３ Ｎｏ．２ Ｐ１６〜１８）これは他の切り花や果物の条件値に近く、本発明のＭＡ貯蔵の条件値よりは酸素濃度がかなり低い。
【０００３】
【発明が解決しようとする課題】
本発明は、キクの従来からの貯蔵方法には前記したような種々の問題を解決するもので、キクをＭＡ包装により確実に鮮度を保ち、且つ経済的に貯蔵することにより、消費者が鮮度が良く安価なキクをいつでも入手可能にすることある。
【０００４】
【課題を解決するための手段】
本発明は、キクを１ヶ月程度の長期に渡り鮮度良くＭＡ貯蔵するための方法にあり、キクを１Ｋｇ当たり酸素、及び二酸化炭素透過量４，０００〜８，０００（ｃｃ／袋／２４ｈ／ａｔｍ）の合成樹脂フィルムにより密封包装し、０〜５℃の雰囲気中に置き包装体内の酸素濃度を１０〜１９％、二酸化炭素濃度を１〜１０％にすることにあり、望ましくは、該フィルムの酸素、及び二酸化炭素透過量を６，０００〜７，０００（ｃｃ／袋／２４ｈ／ａｔｍ）にし、包装体内の酸素濃度を１５〜１８％、二酸化炭素濃度を２〜５％にすることを特徴とするキクの貯蔵方法である。またキクを段ボール箱などの箱に入れた後、該箱の外側を該合成樹脂フィルムにより密封包装することを特徴とするキクの貯蔵方法である。
【０００５】
キクをＭＡ貯蔵により、ＣＡ貯蔵と同じ様に酸素濃度約２％、炭酸ガス濃度約２％の状態にする事も不可能ではないが、このためにはポリエチレンなどの酸素より二酸化炭素を選択的に透過するフィルムを用いる必要がある。ポリエチレンでキクを包装する場合には、その酸素透過量が物性値として決まった物であるため、本発明者らの計算によればポリエチレン（２５μｍ厚）１ｍ２で作製した大袋に１袋当たり大輪キク２０本程度しか包装できず、非常に非合理であり大量貯蔵するには問題がある。また、ポリエチレンは製造時にピンホールの発生が避けられず、特に５０μｍ厚以下の物には発生率が高く酸素透過量のバラツキが出てくる。逆にピンホールをなくすため厚くすれば、当然酸素透過量が下がり１ｍ２に包装できるキクの本数が更に減ってくる。
【０００６】
本発明の合成樹脂フイルムを用いた袋は、包装するキクの量によってその酸素、及び二酸化炭素透過度が決められる。その透過量は、キクの呼吸量により決めることが出来るが、０〜５℃貯蔵でキク１Ｋｇ当たり４，０００〜８，０００（ｃｃ／袋／２４ｈ／ａｔｍ）が適当なことが分かった。この酸素、及び二酸化炭素透過量を合成樹脂フィルムで得る方法は、種々あるが、単層フィルムを用いる方法としては、ポリスチレンなどのガス透過性の比較的高いフィルムを用いてその厚さと面積で調節する方法、複合フィルムを用いる方法としては、ポリブタジエンやポリメチルペンテンなどの高ガス透過性フィルムとシール層としてポリエチレンを用い、それぞれの厚さと袋にした時の表面積とで調節する方法などが上げられ、さらにフィルムに機械加工を行い前記の透過量を得る方法としては、フィルムに貫通、又は未貫通の孔加工を行う方法や、フィルムをダイヤモンドなどの鋭利な物質を表面に取り付けたロールに連続的に強く押しつけて、フィルム表面にクラックを起こさせる方法、フィルムの一部分に前記の透過度を得るためのフィルター（ベンチレーター）を貼り付ける方法などがあり、これらのいくつかの方法を併用してもなんら差し支えなく、またその方法を特に問うものではない。
機械加工して用いる合成樹脂フィルムとしては、キクの包装に用いることのできるものであればどのようなものであっても差し支えはないが、一般には無延伸ポリプロピレン、延伸ポリプロピレン、ポリエチレン、ポリ塩化ビニール等が用いられるが、これら以外のポリアミド、ポリエステル、ポリカーボネート、ポリスチレン等のフイルム、さらにはこれらの複合フイルムであっても良く、さらには、これらのフイルム表面にシーラント層を設けたものでも、防曇処理したフイルムであっても何等差し支えはない。また、これらのフイルムの厚さは製袋性、取り扱い性、価格などから通常２０〜１００μｍ程度のものが用いられる。さらに、これらのフイルムは透明であっても、不透明であっても良く、また表面に印刷を付したものであっても何等差し支えはない。

[Industrial applications]
According to the present invention, even after chrysanthemum is packaged in a bag of synthetic resin film, the chrysanthemum is kept fresh by so-called MA (= Modified Atmosphere) storage by suppressing respiration of the chrysanthemum in an appropriate atmosphere of oxygen and carbon dioxide. And packaging methods.
[0002]
[Prior art]
Chrysanthemum continues to breathe after being harvested. As a result, the chrysanthemums are actively breathed during storage and distribution after harvesting and until they reach the consumer, thereby continuing to consume nutrients and water in the body and deteriorating the quality. Although respiration can be suppressed to some extent by lowering the temperature, it is not perfect, and at present, cold storage and distribution are not yet perfect.
Chrysanthemums are grown on anniversary due to the overwhelming demand for funeral services. However, demand peaks twice a year in the equinoctial week, the old and new basins, and the year-end and New Year holidays. For this reason, chrysanthemum production centers and florists have been storing them in refrigerators at low temperatures before the period of increasing demand, to cope with shortages and soaring prices.
In addition, funeral homes must always have a certain amount of chrysanthemum stock in order to cope with sudden funerals, and this has been covered by low-temperature storage in refrigerators.
However, in storage at these low temperatures only, when the flowering stage of the flower progresses during storage and it does not meet product standards, or when nutrients are consumed by respiration, even if removed from the refrigerator and used in water, water is sucked up There was a problem that it did not bloom without power.
Furthermore, CA (= Controlled Atmosphere) storage has also been proposed as a technique for storing chrysanthemums. According to this method, the mixing ratio of oxygen, carbon dioxide, and nitrogen that keeps chrysanthemum freshness is best determined experimentally, and this mixed gas is filled in a refrigerator storing chrysanthemum, and the mixing ratio is always maintained. It is a large-scale system that replenishes the shortage while monitoring the gas concentration so that the equipment and operation costs are enormous, and there is a problem that it is not profitable if the chrysanthemum is small.
The mixing ratio of oxygen, carbon dioxide, and nitrogen in the CA storage for this chrysanthemum was about 2: 2: 96 by volume ratio (Reference: Food Distribution Technology Vol.23 No.2 P16-18). And the oxygen concentration is much lower than the condition value for MA storage of the present invention.
[0003]
[Problems to be solved by the invention]
The present invention solves the various problems as described above in the conventional method of storing chrysanthemums. By ensuring that chrysanthemums are kept fresh by MA packaging and economically storing them, consumers can enjoy freshness. But sometimes make cheap chrysanthemums always available.
[0004]
[Means for Solving the Problems]
The present invention resides in a method for storing MA in freshness of MA over a long period of about one month, and stores the chrysanthemum in oxygen and carbon dioxide per kg of 4,000 to 8,000 (cc / bag / 24h / atm). ), Sealed in a synthetic resin film, and placed in an atmosphere of 0 to 5 ° C. so that the oxygen concentration in the package is 10 to 19% and the carbon dioxide concentration is 1 to 10%. The oxygen and carbon dioxide permeation amount is 6,000-7,000 (cc / bag / 24h / atm), the oxygen concentration in the package is 15-18%, and the carbon dioxide concentration is 2-5%. It is a storage method of chrysanthemum. A chrysanthemum storage method characterized in that after chrysanthemums are put in a box such as a cardboard box, the outside of the box is hermetically sealed with the synthetic resin film.
[0005]
It is not impossible to store chrysanthemum in the state of about 2% oxygen concentration and about 2% carbon dioxide gas concentration as in the case of CA storage by MA storage. For this purpose, carbon dioxide is selectively used over oxygen such as polyethylene. It is necessary to use a film that transmits light. When packing chrysanthemum with polyethylene, the amount of oxygen permeation is determined as a physical property value. Therefore, according to the calculation of the present inventors, a large bag made of polyethylene (25 μm thick) 1 m 2 has a large wheel per bag. Only about 20 chrysanthemums can be packed, which is very irrational and problematic for mass storage. In addition, generation of pinholes is unavoidable during production of polyethylene, and the generation rate is high especially for those having a thickness of 50 μm or less, and the oxygen permeability varies. If thick to eliminate pinholes in the reverse, comes further reduced the number of chrysanthemum can be packaged in 1 m 2 of course reduce oxygen permeability.
[0006]
The oxygen and carbon dioxide permeability of a bag using the synthetic resin film of the present invention is determined by the amount of chrysanthemum to be packed. The amount of permeation of the chrysanthemum can be determined by the amount of respiration of the chrysanthemum, but it has been found that 4,000 to 8,000 (cc / bag / 24h / atm) per kg of chrysanthemum when stored at 0 to 5 ° C. There are various methods for obtaining the amount of oxygen and carbon dioxide permeated by a synthetic resin film.However, as a method using a single-layer film, a film having a relatively high gas permeability such as polystyrene is used to adjust the thickness and the area. As a method of using a composite film, there is a method of using a high gas permeable film such as polybutadiene or polymethylpentene and a polyethylene as a sealing layer, and adjusting the thickness and surface area of each bag. Further, as a method of obtaining the above-mentioned permeation amount by performing machining on the film, a method of forming a hole through the film or an unpenetrated hole, or a method in which the film is continuously formed on a roll having a sharp substance such as diamond attached to the surface. To cause cracks on the surface of the film, and to obtain the above-mentioned transmittance on a part of the film. Of the filter there is a method of pasting the (ventilator), not permissible in any way be used in combination of some of these methods, also is not particularly ask that way.
As the synthetic resin film to be machined, any material can be used as long as it can be used for packaging chrysanthemum, but in general, unstretched polypropylene, stretched polypropylene, polyethylene, polyvinyl chloride And the like, but other films such as polyamide, polyester, polycarbonate, and polystyrene, and further, a composite film of these may be used.Furthermore, even those having a sealant layer provided on the surface of these films, anti-fog There is no problem with the processed film. The thickness of these films is usually about 20 to 100 μm from the viewpoints of bag making, handling, and price. Further, these films may be transparent or opaque, and there is no problem even if the film is printed on the surface.
[0007]
【Example】
<< Example 1 >>
When a bag made of a polystyrene film having a thickness of 50 μm and an inner size of 600 × 1,000 mm with an oxygen permeation amount of 3,400 (cc / m 2 / 24h / atm) is prepared, the oxygen permeation amount of the bag becomes about 4 , 100 (cc / bag / 24h / atm). In this bag, 1 kg of chrysanthemum (variety: “Hideyoshi no power”) of stage 2 before cutting was packed and stored at 3 ° C. After 15 days, the oxygen concentration in the bag was 16.5% and the carbon dioxide concentration was 2 After 30 days, they were 12.2% and 3.5%, respectively. Table 1 shows the results of observation of the freshness of the chrysanthemum at that time with respect to the state of occurrence of petal damage, yellowing and wilting of leaves, the degree of progress of flowering, and water retention after storage.
[0008]
<< Example 2 >>

In this bag, 1 kg of chrysanthemum (variety: “Seimei”) of stage 3 before cutting was packed, and the same test as in Example 1 was carried out. As a result, the oxygen concentration in the bag after 15 days was 17.6%, carbon dioxide The concentrations were 3.0% and 30 days later, 17.5% and 3.2%, respectively. Other results are shown in Table 1.
[0009]
<< Example 3 >>
The laminated film of 25 μm thick polymethylpentene and 25 μm thick polyethylene has an oxygen permeability of 7,500 (cc / m 2 / 24h / atm), and when a bag having an inner size of 530 × 1,000 mm is prepared, The oxygen permeation amount is 7,950 (cc / bag / 24h / atm). 1 kg of chrysanthemum of the stage 2 before cutting (variety: “Seiko no Autumn”) was packed in this bag, and the same test as in Example 1 was carried out. As a result, the oxygen concentration in the bag after 15 days was 18.6%, The carbon dioxide concentration was 2.1%, and after 30 days, they were 18.4% and 2.5%, respectively. Other results are shown in Table 1.
[0010]
<< Example 4 >>
In a laminated film of 950 mm width, 25 μm thickness polyethylene terephthalate and 25 μm thickness polyethylene, 330 holes having a diameter of 50 μm were formed per 1 m length, and the oxygen permeation amount was 25,000 (cc / m 2 / 24h / atm). This film was attached to an automatic horizontal pillow packaging machine, and a cardboard box (width x height x height = 300 x 1,000 x 150 mm) containing 5 kg of chrysanthemum (variety: "Seiun") of stage 3 before cutting was placed in each box. Automatic packaging was performed, and the same test as in Example 1 was performed. At this time, the effective length excluding the sealing allowance of the film is 1,200 mm per box, and the oxygen permeation amount is 30,000 (cc / bag / 24h / atm). After 15 days, the oxygen concentration in the bag was 17.2%, the carbon dioxide concentration was 3.4%, and after 30 days, they were 16.9% and 3.7%, respectively. Other results are shown in Table 1.
[0011]
<< Comparative Example 1 >>
When the inside size of the bag is 450 × 1,000 mm with the film of Example 1, the oxygen permeation amount is about 3,100 (cc / bag / 24h / atm). As a result of performing exactly the same test as in Example 1 on this bag, the oxygen concentration in the bag after 15 days was 9.5%, the carbon dioxide concentration was 6.4%, and after 30 days, 8.6% and 7%, respectively. 0.5%. Other results are shown in Table 1.
[0012]
<< Comparative Example 2 >>
When a bag having a hole diameter of 150 μm is formed in the bag of Example 2, the oxygen permeation amount of the bag is 12,000 (cc / bag / 24h / atm). As a result of performing exactly the same test as in Example 2 using this bag, the oxygen concentration in the bag after 15 days was 20.2%, the carbon dioxide concentration was 0.2%, and after 30 days, 20.4% and 0%, respectively. 0.5%. Other results are shown in Table 1.
[0013]
<< Comparative Example 3 >>
The same test as in Example 3 was conducted except that the chrysanthemum of Example 3 was kept alive in water without being packed in a bag. In this case, the atmosphere around the chrysanthemum is exactly the same as the normal state. Table 1 shows other test results.
[0014]
Note: The stage before cutting is the condition of blooming flowers at the time of flowering.
[Reference: Revised edition, "Before Flower Cut" by Seibundo Shinkosha]
-Stage 1 = In many cases, it is too hard to ship at any time.
・ Stage 2 = Hard, but can be shipped according to the timing and market preference.
・ Stage 3 = appropriate time for shipment. Slightly cut.
・ Stage 4 = appropriate time for shipment. It is about the standard.
・ Stage 5 = appropriate time for shipment. Slightly open.
・ Stage 6 = Too open, but may be possible depending on the time and market.
[0015]
【The invention's effect】
The chrysanthemum is sealed and packaged in a bag made of the synthetic resin film of the present invention and stored at a low temperature of 0 to 5 ° C., so that the freshness of the chrysanthemum can be maintained for a long period of about one month. If so, the required quantity can be stably and inexpensively secured. Also, since the required quantity can be secured by storage, the flowering work before shipment can be decentralized, leading to a reduction in labor. In addition, by attaching the bag from the outside of a box such as a cardboard box containing chrysanthemum, the packaging process can be automated, and significant packaging work, reduction and rationalization can be achieved.
