【発明の詳細な説明】
（産業上の利用分野）
本発明は、青果物鮮度保持剤の製造方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing a fruit and vegetable freshness-preserving agent.
（従来技術）
周知のごとく、石炭を燃料として用いる火力発電所、製
鉄所等から石炭灰が多量に廃出され、その量は約２５０
万ｔ／年にもなるとみられている。(Prior art) As is well known, a large amount of coal ash is discharged from thermal power plants, steel mills, etc. that use coal as fuel, and the amount is about 250.
It is estimated that the amount will reach 10,000 tons/year.
このような石炭灰は、一部セメント原料等に用いられて
いるが、大量に処理する適切な方法がないことから大半
は固体廃棄物として埋め立て処分されているのが現状で
ある。Although some of this coal ash is used as a raw material for cement, most of it is currently disposed of in landfills as solid waste because there is no suitable method for processing large amounts of it.
しかして、このような大量に廃出される石炭灰分を有効
活用し、再資源化することが強く要求されているところ
である。Therefore, there is a strong demand to effectively utilize and recycle such large amounts of waste coal ash.
（発明が解決しようとする課題）
本発明は、このような要求をを利に解決する優れた処理
方法を提供するものである。(Problems to be Solved by the Invention) The present invention provides an excellent processing method that advantageously solves these requirements.
（課題を解決するための手段）
本発明の特徴とするところは、石炭灰、製紙スラッジ灰

酸化ナトリウム水溶液を８０〜１８０ｇ／ｆ添加し、こ
れを例えば９０℃以上に加熱する。That is, coal ash includes, for example, coal clinker ash, coal fly ash, etc. In addition, silicic acid such as diatomaceous earth and sodium silicate is added to the ash of papermaking sludge incineration ash, either alone or in combination, as an enrichment agent. system enrichment agent,
An aluminum-based enrichment agent such as aluminum chloride is mixed depending on the fly ash composition, but 1 to 10% (weight ratio) is mixed, and to this mixture, for example, 80 to 180 g/f of an aqueous sodium hydroxide solution is added as an alkaline aqueous medium. , and heat this to, for example, 90° C. or higher.

物の近傍（接触又は近接）に配置することが必要である
。The reaction thus produces zeolite. these are,
It can be used in powdered or granulated form, and can be mixed into fruits and vegetables for preservation, or lined in cardboard boxes for packaging fruits and vegetables, and used for transportation. The freshness-preserving agent produced according to the present invention can be formed into a powder, granule, or plate shape, and can be mixed into fruits and vegetables or used as a lining or filling in a storage container. (contact or proximity).
このようにして青果物の鮮度が保持できる理由は次のご
とく考えられる。The reason why the freshness of fruits and vegetables can be maintained in this way is thought to be as follows.
発生し、これが青果物の周囲に充満すると早期に腐敗す
る。つまり鮮度保持が困難になるが、前記本発明方法に
より製造した物質を近接配置することにより、該物質が
上記ガスを吸着し、青果物周囲のエチレンガス等の濃度
を低下させることによって、吸着剤としての機能を十分
はたし、腐敗の進行を遅延させ鮮度を保持するものと認
められる。When this occurs and fills around fruits and vegetables, they rot quickly. In other words, it becomes difficult to maintain freshness, but by placing the substance produced by the method of the present invention in close proximity, the substance adsorbs the above gas and reduces the concentration of ethylene gas etc. around fruits and vegetables, thereby acting as an adsorbent. It is recognized that it fully performs its functions, slows down the process of spoilage, and maintains freshness.
（実 施 例） 次に本発明の実施例を示す。(Example) Next, examples of the present invention will be shown.
下表に示すように各種の灰と、富化剤、媒質を混合し、
加熱処理し、粉末状の吸着剤として、これを腐敗しやす
い青果物としてバナナと共に容器中に収納した。Mix various types of ash, enrichment agent, and medium as shown in the table below,
The adsorbent was heat-treated and turned into a powdered adsorbent, which was stored in a container together with bananas as perishable fruits and vegetables.
使用したバナナは成熟度の同じ同種のものであり、比較
例として本発明による吸着剤を用いない例を併記した。The bananas used were of the same kind with the same maturity level, and as a comparative example, an example in which the adsorbent according to the present invention was not used was also shown.
下表から明らかのように、本発明によって得た吸着剤を
使用したもの（実施例１〜５）は、保存結果が極めて良
