Abstract
Description
本発明は植物体又はその一部、例えば生花の保存期間を著しく伸ばし、自然な風合いを長期間保つことができる植物保存用液状組成物に関する。 The present invention relates to a liquid composition for plant preservation that can significantly extend the preservation period of a plant or a part thereof, for example, fresh flowers, and can maintain a natural texture for a long period of time.
植物の細胞組織内の水分をポリエチレングリコールやグリセリンを含有した組成物の液と置換させる植物保存液については種々提案されている。例えば、バラ等の切り花を、生花と同様な外観を保持したまま長期間にわたる保存を可能とする処理方法が公表特許公報平４−５０５７６６号に提案されている。この処理方法は、切り花の細胞組織内の水、即ち組織水を脱水した後、組織水をポリエチレングリコールを含有した組成物の液によって置換し、必要に応じて染色を行うものであり、脱水工程、浸透工程、及び乾燥工程を順次経て処理を行い、生花と同様な外観を保持した製品としての切り花を得るものである。 Various plant preservation solutions for replacing water in plant cell tissues with solutions of compositions containing polyethylene glycol or glycerin have been proposed. For example, Japanese Patent Application Laid-Open No. 4-505766 has proposed a treatment method that allows cut flowers such as roses to be stored for a long period of time while maintaining the same appearance as that of fresh flowers. In this treatment method, water in the cell tissue of cut flowers, that is, tissue water is dehydrated, and then the tissue water is replaced with a liquid containing a composition containing polyethylene glycol, and staining is performed as necessary. Then, the treatment is performed sequentially through the permeation process and the drying process to obtain cut flowers as a product having the same appearance as that of fresh flowers.
しかしながら、ポリエチレングリコールを主体とする組成物によって置換された植物の組織は、ある温度以上の場合、大気中の水分を吸収して、植物の保存期間は著しく短くなる。また引用した公表特許公報平４−５０５７６６号の特許請求の範囲第５項に記載されたポリエチレングリコール４００とポリエチレングリコール１０００の混合物で置換した切り花は自然の風合いが著しく損なわれたもので、その風合いはプラスチックで作った造花に近くなる。
本発明は、高湿度の大気中においても、植物体又はその一部、例えば生花の保存期間を著しく伸ばし、自然な風合いを長期間保つことができる植物保存用液状組成物を提供することを目的とする。 An object of the present invention is to provide a liquid composition for plant preservation that can significantly extend the preservation period of a plant or a part thereof, for example, fresh flowers, and maintain a natural texture for a long period of time even in a high humidity atmosphere. And
本発明に係る植物保存用液状組成物は、平均分子量２００〜８００の範囲のポリエチレングリコール、平均分子量１５０〜２０００の範囲のポリプロピレングリコール、並びにメチルアルコール、エチルアルコール及びプロピルアルコールからなる群から選ばれる少なくとも１種の低級アルコールからなり、該ポリエチレングリコール１０〜５０重量％、該ポリプロピレングリコール０．５〜３０重量％で且つ該ポリエチレングリコールと該ポリプロピレングリコールの合計量として１０．５〜６０重量％を含有し残りは該低級アルコールであることを特徴とする。 The liquid composition for plant preservation according to the present invention is at least selected from the group consisting of polyethylene glycol having an average molecular weight of 200 to 800, polypropylene glycol having an average molecular weight of 150 to 2000, and methyl alcohol, ethyl alcohol and propyl alcohol. It consists of one kind of lower alcohol and contains 10 to 50% by weight of the polyethylene glycol, 0.5 to 30% by weight of the polypropylene glycol, and 10.5 to 60% by weight as the total amount of the polyethylene glycol and the polypropylene glycol. The rest is the lower alcohol.
高湿度、例えば湿度８０％の雰囲気中でも花持ちが良く、また風合いを維持する。 Even in an atmosphere of high humidity, for example, 80% humidity, the flower has a good life and maintains the texture.
本発明の植物保存用液状組成物は、平均分子量２００〜８００の範囲で親水性であるポリエチレングリコール及び親水性であるＣ１〜Ｃ３の低級アルコールのほかに、平均分子量１５０〜２０００の範囲で疎水性であるポリプロピレングリコールを含有している。前２者だけでは大気中の水分を吸収して植物の保存期間を著しく短くし、また疎水性のポリプロピレングリコールだけでは十分に植物組織内に置換することができない。 The liquid composition for plant preservation of the present invention is hydrophobic in the range of an average molecular weight of 150 to 2000, in addition to polyethylene glycol that is hydrophilic in the range of an average molecular weight of 200 to 800 and lower alcohols of C1 to C3 that are hydrophilic. Polypropylene glycol which is The former two alone absorb moisture in the atmosphere to shorten the shelf life of the plant significantly, and hydrophobic polypropylene glycol alone cannot sufficiently replace the plant tissue.
ポリエチレングリコールの平均分子量を２００〜８００の範囲とする理由は、平均分子量２００未満では大気中の水分の吸収性が高く花持ち効果が不十分で植物を保存することができず、また平均分子量が８００を越えるものは室温で硬い固体となり、自然な風合いを保つことができないからである。 The reason why the average molecular weight of polyethylene glycol is in the range of 200 to 800 is that if the average molecular weight is less than 200, the moisture absorption in the atmosphere is high, the flower holding effect is insufficient, and the plant cannot be stored, and the average molecular weight is This is because those exceeding 800 become a hard solid at room temperature and cannot maintain a natural texture.
ポリプロピレングリコールの平均分子量を１５０〜２０００の範囲とする理由は、平均分子量１５０未満では花持ち効果が不十分であり、また平均分子量が２０００を越えるものは室温で粘度が高くなり、自然な風合いを保つことができないからである。 The reason why the average molecular weight of polypropylene glycol is in the range of 150 to 2000 is that if the average molecular weight is less than 150, the flower-holding effect is insufficient, and if the average molecular weight exceeds 2000, the viscosity becomes high at room temperature, giving a natural texture. Because it cannot be kept.
平均分子量２００〜８００の範囲のポリエチレングリコールの含有量は、１０〜５０重量％の範囲とする。１０重量％未満では花持ち効果が不十分であり、また５０重量％超では大気中の水分を吸収し易く植物の保存期間が短くなるからである。このポリエチレングリコールは単品でも混合品でも良い。 The content of polyethylene glycol having an average molecular weight in the range of 200 to 800 is in the range of 10 to 50% by weight. This is because if it is less than 10% by weight, the flower-holding effect is insufficient, and if it exceeds 50% by weight, it easily absorbs moisture in the atmosphere and shortens the storage period of the plant. This polyethylene glycol may be a single product or a mixed product.
平均分子量１５０〜２０００の範囲のポリプロピレングリコールの含有量は、０．５〜３０重量％の範囲とする。０．５重量％未満では大気中の水分を吸収し易く植物の保存期間が短くなり、３０重量％超では組成物を十分に植物組織内に置換することができないからである。このポリプロピレングリコールは単品でも混合品でも良い。 The content of polypropylene glycol having an average molecular weight of 150 to 2,000 is in the range of 0.5 to 30% by weight. If the amount is less than 0.5% by weight, moisture in the air is easily absorbed and the storage period of the plant is shortened. If the amount exceeds 30% by weight, the composition cannot be sufficiently substituted into the plant tissue. This polypropylene glycol may be a single product or a mixed product.
ポリエチレングリコールとポリプロピレングリコールの合計量は、１０．５〜６０重量％の範囲とする。１０．５重量％未満では植物を保存するに十分な十分な量を置換することができず、６０重量％超では自然な風合いを保つことができない。 The total amount of polyethylene glycol and polypropylene glycol is in the range of 10.5 to 60% by weight. If the amount is less than 10.5% by weight, a sufficient amount for preserving the plant cannot be replaced, and if it exceeds 60% by weight, the natural texture cannot be maintained.
残りの成分はメチルアルコール、エチルアルコール及びプロピルアルコールからなる群から選ばれる少なくとも１種の低級アルコールである。このアルコールは単品でも混合品でも良い。その含有量はポリエチレングリコール及びポリプロピレングリコールの含有量によって律せられる。本組成物は植物の組織が保有している組織水と置換された後、アルコールは植物体内から蒸発する必要がある。そのために使用するアルコールは低沸点のＣ１からＣ３のアルコール（メチルアルコール：沸点６４．１℃、エチルアルコール：沸点７８．３℃、プロピルアルコール：沸点９７．４℃のいずれか又はそれらの混合物である必要がある。特にメチルアルコール又はエチルアルコールのいずれか一方又はそれらの混合物が好ましい。 The remaining component is at least one lower alcohol selected from the group consisting of methyl alcohol, ethyl alcohol, and propyl alcohol. This alcohol may be a single product or a mixed product. Its content is determined by the content of polyethylene glycol and polypropylene glycol. After the composition is replaced with the tissue water held by the plant tissue, the alcohol needs to evaporate from the plant body. The alcohol used for this purpose is a low-boiling C1 to C3 alcohol (methyl alcohol: boiling point 64.1 ° C, ethyl alcohol: boiling point 78.3 ° C, propyl alcohol: boiling point 97.4 ° C, or a mixture thereof. In particular, either methyl alcohol or ethyl alcohol or a mixture thereof is preferable.
