【発明の詳細な説明】
（産業上の利用分野）
本発明は、エチレンガス吸収組成物に関し、更に詳しく
は、野菜や果物等の生鮮食品の鮮度保持に有用なエチレ
ンガス吸収組成物に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an ethylene gas absorbing composition, and more particularly to an ethylene gas absorbing composition useful for preserving the freshness of fresh foods such as vegetables and fruits.
（従来の技術及びその問題点）
従来、野菜や果物等の生鮮食品等の大量保存は低温保存
や冷凍保存によって行われているが、小売店等の店頭で
小分けして陳列及び販売される場合には、上記の如き大
量保存は不可能である。(Conventional technology and its problems) Conventionally, large quantities of fresh foods such as vegetables and fruits have been preserved by low-temperature storage or frozen storage, but when they are displayed and sold in small portions at retail stores, etc. , it is impossible to store such a large amount as described above.
従って小売店等ではこれらの生鮮食品等を皿状の簡便な
容器に収納し、合成樹脂フィルムによりラップして店頭
で陳列及び販売している場合が多い。Therefore, in retail stores, these fresh foods and the like are often stored in simple dish-shaped containers, wrapped in synthetic resin film, and displayed and sold at the store.
このような場合、野菜や果物等の生鮮食品は。In such cases, fresh foods such as vegetables and fruits.
自己の生理作用によりエチレンガスを発生し、該エチレ
ンガスの雰囲気下に置かれた生鮮食品は、エチレンガス
の作用により完熟及び劣化が促進され、店頭で陳列及び
販売される際には非常に日持ちか悪いという問題かある
。勿論家庭内でも同様な問題がある。Fresh food that generates ethylene gas due to its own physiological action and is placed in an ethylene gas atmosphere accelerates ripening and deterioration due to the action of ethylene gas, and has a very long shelf life when displayed and sold in stores. There is a problem with whether it is bad or not. Of course, similar problems exist at home.
このような問題点を解決する方法としては、ガス吸着性
に優れた活性炭を容器内に入れたり、容器壁に内包させ
てエチレンガスを吸収する方法が知られているが、活性
炭を大量に使用すると活性炭の吸着力が大であり、且つ
ガス成分に対する吸着選択性が無いため、内容物である
食品の鮮度維持に有害であるエチレンガスのみならず、
食品の好ましい香気成分や香味成分をも吸着するため、
包装を開封した時に消費者が期待する食品の香気成分や
香味成分が失われ、消費者に対して味気ない感じを与え
るという問題がある。Known methods to solve these problems include placing activated carbon, which has excellent gas adsorption properties, inside the container or encapsulating it in the container wall to absorb ethylene gas, but using a large amount of activated carbon Activated carbon has a large adsorption power and has no adsorption selectivity for gas components, so it absorbs not only ethylene gas, which is harmful to maintaining the freshness of the food contained therein.
Because it also absorbs desirable aroma and flavor components of foods,
There is a problem in that when the consumer opens the package, the aroma and flavor components of the food that the consumer expects are lost, giving the consumer a bland feeling.
一方、これらの問題点を解決するために活性炭の使用量
を少なくすると、エチレンガスを十分に吸着除去できな
いため、鮮度維持は不十分となる。On the other hand, if the amount of activated carbon used is reduced in order to solve these problems, ethylene gas cannot be sufficiently adsorbed and removed, resulting in insufficient freshness maintenance.
従って、本発明の目的は、生鮮食品が発生するエチレン
ガスを効率よく吸収し、生鮮食品の鮮度保持に有効なエ
チレンガス吸収組成物を提供することである。Therefore, an object of the present invention is to provide an ethylene gas absorbing composition that efficiently absorbs ethylene gas generated by fresh foods and is effective in maintaining the freshness of fresh foods.
（問題点を解決するための手段） 北記目的は以下の本発明によって達成される。(Means for solving problems) The above objects are achieved by the present invention as follows.
すなわち、本発明は、樹脂５乃至９５重量部及びエチレ
ンガス吸収剤９５乃至５重量部からなるエチレンガス吸
収組成物において、エチレンガス吸収剤が活性炭と金属
酸化物との混合物であることを特徴とするエチレンガス
吸収組成物である。That is, the present invention provides an ethylene gas absorbing composition comprising 5 to 95 parts by weight of a resin and 95 to 5 parts by weight of an ethylene gas absorbent, characterized in that the ethylene gas absorbent is a mixture of activated carbon and a metal oxide. This is an ethylene gas absorbing composition.
（作 用）
活性炭と金属酸化物との混合物をエチレンガス吸収剤と
して使用することにより、生鮮食品の発生するエチレン
ガスを選択的に効率よく吸収でき、小量の活性炭で十分
な鮮度保持が可能となる。(Function) By using a mixture of activated carbon and metal oxide as an ethylene gas absorbent, the ethylene gas generated by fresh foods can be selectively and efficiently absorbed, and a small amount of activated carbon can maintain sufficient freshness. becomes.
