Description
本発明は、収穫後、保存流通中のニンニクの発芽発根を抑制するニンニクの発芽発根抑制剤包装体及び発芽発根抑制方法に関するものである。また、エチレン発生包装体に関するものである。本発明で、ニンニクとはニンニク類の通常食用に供されるリン茎（球）部分を指す。発芽発根の抑制とは、発芽の抑制、発根の抑制あるいは発芽と発根の両方の抑制を含む。 The present invention relates to a garlic germination root inhibitor package and a germination root suppression method for suppressing germination and rooting of garlic during storage and distribution after harvesting. The present invention also relates to an ethylene generating package. In the present invention, garlic refers to a portion of a phosphorus stalk (sphere) that is used for normal consumption of garlic. Suppression of germination and rooting includes suppression of germination, suppression of rooting, or suppression of both germination and rooting.
ニンニクは６月中旬頃収穫されるが、これを常態で放置すると１０月頃に発芽発根し始める。ニンニクは年間を通じて食用とされる為、出来るだけ発芽発根しない状態で保持されることが望ましい。発芽抑制の方法として、例えば、−３〜２℃に管理された低温貯蔵や、−１〜０℃、酸素濃度３〜４％、炭酸ガス濃度４〜５％のＣＡ貯蔵が効果的であることが知られている（非特許文献１）。また、０〜１℃で６５〜７５％の湿度で貯蔵する方法も知られている（特許文献１）。しかし、これらの低温を利用した発芽抑制方法は、生産地の貯蔵庫では可能であるが、その流通過程においては、実際にそのような条件を満足させるには制御された冷蔵設備が必要であり、安価で容易な方法とは言えなかった。発芽抑制剤として、マレイン酸ヒドラジドコリンやマレイン酸ヒドラジドカリウム等の製剤の葉面散布がニンニクの発芽抑制に効果のあることも知られているが、最近、これら製剤の安全性が問題になってきている。このため、収穫後のニンニクの貯蔵開始から流通消費までの流通過程において、安全性が高く、安価なニンニクの発芽発根抑制剤及びその発芽発根抑制方法が求められている。 Garlic is harvested around mid-June, but if left in a normal state, it begins to germinate and root around October. Since garlic is edible throughout the year, it is desirable to keep it in a state where it does not germinate as much as possible. As a method of inhibiting germination, for example, low-temperature storage controlled at -3 to 2 ° C or CA storage at -1 to 0 ° C, oxygen concentration 3 to 4%, carbon dioxide concentration 4 to 5% is effective. Is known (Non-Patent Document 1). Moreover, the method of storing at 65-75% humidity at 0-1 degreeC is also known (patent document 1). However, germination control methods using these low temperatures are possible in storage in the production area, but in the distribution process, controlled refrigeration equipment is actually required to satisfy such conditions, It was not an inexpensive and easy method. As a germination inhibitor, it is known that foliar spraying of preparations such as hydrazide choline maleate and potassium hydrazide maleate is effective in inhibiting germination of garlic, but recently, the safety of these preparations has become a problem. ing. For this reason, in the distribution process from the start of storage of garlic after harvesting to distribution consumption, a garlic germination root inhibitor and a germination root suppression method that are highly safe and inexpensive are required.
一方、エチレンは、多くの種子の発芽を促進することが知られている（非特許文献２）。ニンニクに対しても、エチレンの排除が発芽抑制効果を有すると考えられてきた（特許文献１）。
また、馬鈴薯・甘藷などの根菜類を、エチレン発生果菜類とともに発泡合成樹脂容器内に保存したり、貯蔵庫内でエチレン生成菌のようなエチレンガス発生体を共存させたり、エチレンガスを導入する方法が知られている（特許文献２、３）。しかし、ニンニクは葉茎菜類に属し根菜類ではなく、また、ニンニクと同じ茎菜類のアスパラガスがエチレンによって逆に発芽促進されることも知られている。従って、エチレンの及ぼす発芽促進及び抑制効果は、個別の植物について評価されるべきものであって、少なくともニンニクがエチレンによって発芽抑制されるということは知られていないというべきである。
Also, root vegetables such as potatoes and sweet potatoes are stored in foamed synthetic resin containers together with ethylene-producing fruit vegetables, ethylene gas generators such as ethylene-producing bacteria are coexisted in the storage, or ethylene gas is introduced. Is known (Patent Documents 2 and 3). However, garlic belongs to leaf stem vegetables and is not a root vegetable, and it is also known that asparagus from the same stem vegetables as garlic is reversely germinated by ethylene. Therefore, the germination promoting and inhibiting effects of ethylene should be evaluated for individual plants, and it should be said that at least garlic is germinated and inhibited by ethylene.
本発明の目的は、従来技術の上記した課題を解決して、収穫された後、食用として料理や加工に供されるまでの保管流通中のニンニクの発芽発根を抑制するニンニクの発芽発根抑制剤包装体及び発芽発根抑制方法を提供することにある。 The object of the present invention is to solve the above-mentioned problems of the prior art and to prevent germination and rooting of garlic which suppresses germination and rooting of garlic during storage and distribution until harvested and used for cooking and processing. It is providing the inhibitor package and the germination root suppression method.
本発明者らは、ニンニクの発芽発根抑制方法について鋭意研究を重ねた結果、これまで青果物類の発芽促進剤と考えられていたエチレンガスが、意外にもニンニクには抑制効果があることを見出した。そして、エチレンガスを持続的にニンニクの周辺の雰囲気に存在させることによって、好適にニンニクの発芽発根を抑制出きることを見出し、本発明を完成させた。 As a result of intensive research on germination and root suppression methods for garlic, the present inventors have found that ethylene gas, which has been considered to be a germination promoter for fruits and vegetables, has a surprisingly effective inhibitory effect on garlic. I found it. And it discovered that the germination rooting of a garlic could be suppressed suitably by making ethylene gas exist in the atmosphere around a garlic continuously, and completed this invention.
すなわち、本発明は、エチレンを吸着させた吸着性担体を、透湿度が０．１〜１００ｇ／ｍ２・D(１０℃・１００％RH)の限定された通気性包材で包装したエチレン発生包装体、該エチレン発生包装体からなるニンニクの発芽発根抑制剤包装体、並びに、該エチレン発生包装体をニンニクと共に通気性の保存容器に収納することによるニンニクの発芽発根抑制方法に関する。 That is, the present invention relates to ethylene generation in which an adsorbent carrier on which ethylene is adsorbed is packaged with a breathable packaging material having a moisture permeability of 0.1 to 100 g / m 2 · D (10 ° C. · 100% RH). The present invention relates to a garlic germination root inhibitor package comprising the package, the garlic germination root suppressant, and a garlic germination root suppression method by storing the ethylene generation package together with garlic in a breathable storage container.
本発明においては、エチレンを吸着させた吸着性担体を０．１〜１００ｇ／ｍ２・D(１０℃・１００％RH)である通気性包材で包装したエチレン発生包装体を、エチレン発生剤として用いる。用いられる吸着性担体は、エチレンを一旦吸着後、放散するものであれば特に制限されないが、ゼオライト、シリカゲル、活性炭などがあげられ、ゼオライトが好ましい。 In the present invention, an ethylene generating package in which an adsorbent carrier on which ethylene is adsorbed is packaged with a breathable packaging material of 0.1 to 100 g / m 2 · D (10 ° C. · 100% RH) Used as The adsorptive carrier to be used is not particularly limited as long as it once adsorbs ethylene and then dissipates, and examples thereof include zeolite, silica gel, activated carbon and the like, and zeolite is preferable.
エチレンを吸着させた吸着性担体において、エチレンの吸着性担体への吸着量は、吸着性担体１gに対して、０．５〜３０mg、好ましくは、１０〜３０mgであり、該担体の使用量は、ニンニク１Kgに対して１〜１００ｇが好ましい。 In the adsorbent carrier to which ethylene is adsorbed, the amount of ethylene adsorbed on the adsorbent carrier is 0.5 to 30 mg, preferably 10 to 30 mg, with respect to 1 g of the adsorbent carrier. 1 to 100 g is preferable with respect to 1 kg of garlic.
本発明の通気性包材は、０．１〜１００ｇ／ｍ２・D(１０℃・１００％RH)、好ましくは、０．１〜１０ｇ／ｍ２・D(１０℃・１００％RH)に限定された範囲の透湿性を有する包装フィルム材料である。本発明の通気性包材の透湿性は、１０℃・１００％RHの環境下で測定される。例えば、通気性包材で作製した小袋にシリカゲルを封入して、１０℃、１００％RHの雰囲気に放置して、放置前後の小袋重量差を測定することにより、通気性包材面積当たり24時間の透湿度として求めることが出来る。 The breathable packaging material of the present invention is 0.1 to 100 g / m 2 · D (10 ° C. · 100% RH), preferably 0.1 to 10 g / m 2 · D (10 ° C. · 100% RH). A packaging film material having a limited range of moisture permeability. The moisture permeability of the breathable packaging material of the present invention is measured under an environment of 10 ° C. and 100% RH. For example, by enclosing silica gel in a sachet made of a breathable packaging material, leaving it in an atmosphere of 10 ° C. and 100% RH, and measuring the difference in the weight of the sachet before and after being left for 24 hours per area of the breathable packaging material It can be calculated as moisture permeability.
エチレンを吸着させた吸着性担体は、通気性包材で包装した小袋等の包装体で、ニンニクの近傍に放置して使用する。ここで、通気性包材とは、ニンニクから蒸散する水分を透過し、エチレンを吸着させた吸着性担体から発生するエチレンを良好に通気する包材である。ニンニクから蒸散した水分は通気性包材を透過して内部の吸着性担体に吸着され、代わってエチレンが放出される。 The adsorbent carrier on which ethylene has been adsorbed is used by leaving it in the vicinity of garlic in a package such as a sachet wrapped with a breathable packaging material. Here, the air-permeable packaging material is a packaging material that permeates moisture evaporated from garlic and favorably vents ethylene generated from the adsorbent carrier on which ethylene is adsorbed. Moisture evaporated from the garlic permeates through the breathable packaging material and is adsorbed on the internal adsorbent carrier, releasing ethylene instead.
本発明の通気性包材としては、前記範囲の透湿性を有するポリエチレンやポリプロピレン等のポリオレフィン樹脂フィルムが好適に用いられる。また、前記ポリオレフィンからなる無孔の樹脂フィルム、または、この樹脂フィルムに透湿性に影響を与えない微多孔膜、不織布、紙等を組み合わせてラミネートした包材が使用できる。このような特定の透湿性を有する樹脂フィルムまたは樹脂フィルムラミネート包材は、適度に水蒸気を透過させ、透過した水分がエチレンを吸着させた吸着性担体にエチレンと置換して吸着される為、エチレンを徐々に放出させてエチレンによるニンニクの保存効果を長期に維持することができる。 As the breathable packaging material of the present invention, a polyolefin resin film such as polyethylene or polypropylene having moisture permeability in the above range is suitably used. Moreover, a non-porous resin film made of the polyolefin, or a packaging material obtained by laminating a combination of a microporous film, a nonwoven fabric, paper, or the like that does not affect moisture permeability on the resin film can be used. Such a resin film or resin film laminate packaging material having a specific moisture permeability allows water vapor to permeate appropriately, and the permeated water is adsorbed by substituting ethylene with an adsorbent carrier on which ethylene is adsorbed. The garlic preservation effect of ethylene can be maintained over a long period of time by gradually releasing.
ニンニクは密封状態にすると、発芽発根が促進されるのみならず、カビや腐敗を誘発する。一方、エチレンの存在する雰囲気にニンニクを放置するため、外界との適度な隔離も必要である。この為、本発明において、ニンニクは通気性の保存容器に収納される。このような通気性の保存容器として、段ボール箱が例示される。 When sealed, garlic not only promotes germination and rooting, but also induces mold and rot. On the other hand, in order to leave garlic in an atmosphere in which ethylene is present, it is also necessary to provide appropriate isolation from the outside world. For this reason, in the present invention, garlic is stored in a breathable storage container. A cardboard box is exemplified as such a breathable storage container.
本発明によれば、安全性が高く、作業も容易に、ニンニクの発芽発根を効果的に抑制でき、良好な状態で長期の保存が可能になる。本発明は、特に、冷蔵条件や、ＣＡ貯蔵条件が適用できないような流通の環境条件においても、ニンニクの発芽発根を長期に効果的に抑制する。
本発明のエチレン包装体は、エチレンを徐々に放出させてエチレンによるニンニクの保存効果を長期に維持することができる。
本発明の方法により保存されたニンニクは、有害薬品を含まないので、業務用にも、一般消費者用の食材としても好適に用いられ、食品産業上の利用価値は極めて高い。
According to the present invention, garlic germination rooting can be effectively suppressed with high safety and easy work, and long-term storage can be performed in a good state. In particular, the present invention effectively suppresses germination and rooting of garlic for a long period of time even under refrigerated conditions and distributional environmental conditions where CA storage conditions cannot be applied.
The ethylene package of the present invention can gradually release ethylene to maintain the storage effect of garlic by ethylene for a long time.
Since the garlic preserved by the method of the present invention does not contain harmful chemicals, it can be suitably used as a food material for business use or general consumers, and its utility value in the food industry is extremely high.
本発明のニンニクの発芽発根抑制方法は、ニンニクをエチレン発生剤包装体と共に通気性の保存容器に収納し、保存することにより実施される。
本発明は、発芽発根前のニンニクに適用でき、特に、収穫後約２０日以降の萌芽期のニンニク、具体的には、収穫後、低温貯蔵したニンニクの流通過程での発芽発根抑制に利用できる。
The method for inhibiting germination and rooting of garlic according to the present invention is carried out by storing garlic in an air-permeable storage container together with an ethylene generator package.
The present invention can be applied to garlic before germination and rooting, and in particular, to suppress germination and rooting in the distribution process of garlic in the germination period after about 20 days after harvest, specifically, garlic stored at low temperature after harvest. Available.
本発明において、ニンニクが収納される通気性の保存容器の材質は、紙や不織布、微多孔膜などが用いられる。保存容器の形態や厚みは、ニンニクの量にもより、特に制限はないが、実用的には、少量の場合は４０μから１００μ程度の紙袋や、不織布や微多孔膜をラミネートした包材を容器の一部に使用したもの、紙に孔のあいたプラステイックフィルムをラミネートした包装容器等が用いられ、業務用になると、厚み２ｍｍ程度の一般的な段ボール箱が用いられる。又、これらの包装体をニンニク1〜10個程度と共にネットに収納し、このネットを集積して段ボールに入れて使用することもある。 In the present invention, paper, a nonwoven fabric, a microporous film, or the like is used as the material of the breathable storage container in which garlic is stored. The shape and thickness of the storage container are not particularly limited depending on the amount of garlic, but practically, in the case of a small amount, a paper bag of about 40 to 100 μm, or a packaging material laminated with a nonwoven fabric or a microporous film is used For example, a packaging container in which a plastic film having a hole in paper is laminated is used. For business use, a general cardboard box having a thickness of about 2 mm is used. Moreover, these packaging bodies may be stored in a net together with about 1 to 10 garlics, and the nets may be collected and used in cardboard.
本発明は、管理された低温貯蔵庫やＣＡ貯蔵庫を必要とせずに実施できる。すなわち、ニンニクを本発明のエチレン発生剤包装体と共に通気性の保存容器に収納し、３０℃以下の温度で保存してもニンニクの発芽発根抑制効果があり、２０℃以下好ましくは１０℃以下の温度で保存すれば、より高いニンニクの発芽発根抑制効果がある。本発明の方法は、勿論、低温貯蔵庫やＣＡ貯蔵庫内でも適用できる。 The present invention can be practiced without the need for a controlled cold storage or CA storage. That is, even if garlic is stored in a breathable storage container together with the ethylene generator package of the present invention and stored at a temperature of 30 ° C. or less, it has an effect of suppressing germination and rooting of garlic, 20 ° C. or less, preferably 10 ° C. or less. If it preserve | saves at the temperature of, the germination rooting inhibitory effect of a higher garlic is higher. Of course, the method of the present invention can also be applied in a cold storage or a CA storage.
本発明は、低温貯蔵またはＣＡ貯蔵されたニンニクを流通する際に、厳密な温度管理を必要とせずに容易に実施できるので、大きな利用価値がある。このような場合、予め低温下で、ニンニクをエチレン発生包装体とともに、通気性保存容器に収納した後、常温等の保存条件に移行する方法を取ることによって、より効果的な利用が出来る。
本発明により保存されるニンニクは、業務用にも、一般消費者用の食材としても好適に用いられ、食品産業上の利用価値は極めて高い。
The present invention has great utility value because it can be easily implemented without requiring strict temperature control when circulating garlic stored at low temperature or CA. In such a case, the garlic can be stored in a breathable storage container together with the ethylene-generating package in advance at a low temperature, and then transferred to storage conditions such as room temperature for more effective use.
The garlic preserve | saved by this invention is used suitably as a foodstuff for business and general consumers, and its utility value in a food industry is very high.
