Abstract
Description
本発明は、鉄−ポリフェノール複合材を含有する消臭剤および該消臭剤を用いる消臭方法に関する。 The present invention relates to a deodorant containing an iron-polyphenol composite material and a deodorizing method using the deodorant.
従来から、茶やコーヒーなどの粉を用いた消臭効果があることが知られており、茶などに含まれるフラボノイドなどのポリフェノール成分は、その抗酸化作用や、水酸基によるアンモニアなどの悪臭物質の分解による効果により消臭剤への利用例が報告されている（特許文献１、２など）。 It has been known that it has a deodorizing effect using powders such as tea and coffee, and polyphenol components such as flavonoids contained in tea and the like have an antioxidant effect and a malodorous substance such as ammonia due to hydroxyl groups. Examples of its use as a deodorant due to the effect of decomposition have been reported (Patent Documents 1, 2, etc.).
一方、消臭効果を有する無機物として、鉄は２価の鉄イオン（Ｆｅ２＋）の状態で、悪臭物質を吸着する効果により消臭効果を示すため、空気中で２価鉄の酸化を防止するための鉄−有機化合物などの複合材を消臭剤として利用しようとする研究が報告されている（特許文献３など）。 On the other hand, as an inorganic substance having a deodorizing effect, iron exhibits a deodorizing effect by the effect of adsorbing malodorous substances in the state of divalent iron ions (Fe 2+ ), so that oxidation of divalent iron is prevented in the air. Studies have been reported in which a composite material such as an iron-organic compound for this purpose is used as a deodorant (Patent Document 3 and the like).
これらの茶やコーヒーが含有するポリフェノールと２価鉄を複合化させた、鉄−ポリフェノール材料の開発が近年行われており（特許文献４〜６）、農業や食品業界での環境負荷の少ない殺菌剤、防腐剤や、排水中の汚染物質分解などの材料として期待されている。 In recent years, iron-polyphenol materials, which are composites of polyphenols contained in these teas and coffees and divalent iron, have been developed (Patent Documents 4 to 6), and sterilization with less environmental load in the agriculture and food industries. It is expected as a material for agents, preservatives, and decomposition of pollutants in wastewater.
市販の消臭剤は、液体中に消臭成分を溶解させたものや、活性炭など表面への物理吸着を応用としたもの、または両者を組み合わせて、消臭効果を長期間持続させようとするものがあるが、環境への影響を考慮し、自然物由来の材料を用い、繰り返し使用できるものは、今なお求められている。 Commercially available deodorants are those in which deodorant components are dissolved in a liquid, those that apply physical adsorption to the surface such as activated carbon, or a combination of both to maintain the deodorant effect for a long period of time. There are some, but in consideration of the impact on the environment, those that use materials derived from natural substances and can be used repeatedly are still in demand.
本発明は、鉄、鉄化合物などの鉄成分と、茶やコーヒーなどに含まれるポリフェノール成分とを反応させて得られる鉄−ポリフェノール複合材を含有する消臭剤を提供し、該消臭剤を用いる消臭方法を提供することを目的とする。 The present invention provides a deodorant containing an iron-polyphenol composite material obtained by reacting an iron component such as iron or an iron compound with a polyphenol component contained in tea or coffee, and using the deodorant.

本発明の「鉄−ポリフェノール」は、前記鉄原料と、前記ポリフェノール源とを反応させて得られる。具体的には、鉄原料は、硫酸鉄（ＩＩ）、塩化鉄（ＩＩＩ）、などの鉄化合物、もしくはそれらが水に溶解した溶液の状態で、鉄イオンが容易にポリフェノール源と接することができるものが好ましい。ポリフェノール源としては、茶やコーヒーが適しており、それらは、使用前でも使用後のものでもよく、飲料用に成分を抽出し、ポリフェノール成分がある程度溶出した茶殻やコーヒー粕でもよい。 The "iron-polyphenol" of the present invention is obtained by reacting the iron raw material with the polyphenol source. Specifically, the iron raw material is an iron compound such as iron (II) sulfate, iron (III) chloride, or a solution in which they are dissolved in water, and iron ions can easily come into contact with the polyphenol source. Is preferable. Suitable sources of polyphenols are tea and coffee, which may be pre-use or post-use, or tea leaves or coffee grounds from which the components have been extracted for beverage use and the polyphenol components have been eluted to some extent.
鉄−ポリフェノールの製造方法は、例えば特許文献４など公知の方法で製造することができる。具体的な製造例を示すが、温度や加熱時間などの製造条件は、原料の量などにより適宜選択される。例えば、硫酸鉄（ＩＩ）や塩化鉄（ＩＩＩ）などの鉄化合物と、ポリフェノールを含有する茶などの粉体と、水とを混合し、７０℃以上、好ましくは９５℃〜１１０℃で、少なくとも１時間以上加熱し反応させ、鉄とポリフェノールを結合させて、３価鉄は安定な２価鉄に還元される。混合時における茶と鉄源における鉄の比率は、適宜設定することができ、たとえば、乾燥した茶に対して鉄が０．１〜２０質量％などの範囲で混合することができる。鉄成分およびポリフェノール源と水との混合比は適宜設定することができ、たとえば、（鉄成分＋ポリフェノール源）の質量に対して、１／２〜１００倍の質量の水を混合することができるが、１／２〜２０倍の質量の水が好ましい。このとき、ポリフェノール原料の種類により、ポリフェノールの分子構造や、鉄とポリフェノールの結合する組成比が異なるため、鉄−ポリフェノールの分子構造が１種類とは限定されない。反応後、余分な水分などの成分を加熱して乾燥、除去することにより、鉄−ポリフェノールを含有する複合材（鉄−ポリフェノール複合材）を得ることができる。乾燥温度は、水分が除去できる温度であれば、限定されないが、常温での自然乾燥でも７０℃以上でも乾燥可能だが、９５℃以上の高温であることが時間短縮のためには好ましい。乾燥後の鉄−ポリフェノール複合材の含水率は、１５％以下が好ましいが、保存のためにはより少ない方が好ましく、１０％以下がより好ましい。 The iron-polyphenol can be produced by a known method such as Patent Document 4. A specific production example will be shown, but production conditions such as temperature and heating time are appropriately selected depending on the amount of raw materials and the like. For example, an iron compound such as iron (II) sulfate or iron (III) chloride, a powder such as tea containing polyphenol, and water are mixed and mixed at 70 ° C. or higher, preferably 95 ° C. to 110 ° C., at least. The iron and polyphenol are combined by heating and reacting for 1 hour or more, and the ferric iron is reduced to stable ferric iron. The ratio of iron in the tea to the iron source at the time of mixing can be appropriately set, and for example, iron can be mixed in the range of 0.1 to 20% by mass with respect to the dried tea. The mixing ratio of the iron component and the polyphenol source and water can be appropriately set. For example, water having a mass of 1/2 to 100 times the mass of (iron component + polyphenol source) can be mixed. However, water having a mass of 1/2 to 20 times is preferable. At this time, the molecular structure of iron-polyphenol is not limited to one type because the molecular structure of polyphenol and the composition ratio of binding iron and polyphenol differ depending on the type of polyphenol raw material. After the reaction, an iron-polyphenol-containing composite material (iron-polyphenol composite material) can be obtained by heating, drying, and removing excess water and other components. The drying temperature is not limited as long as it can remove water, but it can be dried naturally at room temperature or at 70 ° C. or higher, but a high temperature of 95 ° C. or higher is preferable for shortening the time. The water content of the iron-polyphenol composite material after drying is preferably 15% or less, preferably less for storage, and more preferably 10% or less.
鉄−ポリフェノールやその複合材の製造時に使用する水は、特に限定されず、通常の水でよく、例えば、井戸水、河川・湖沼水、海水、水道水、農業用水、工業用水、脱イオン水、蒸留水などがあげられる。本発明の有利な効果を妨げない限り、ｐＨ緩衝剤、塩（ＮａＣｌ、ＫＣｌなど）、アルコール（エタノールなど）、糖類、酸、アルカリなどを含むものであってもよい。 The water used in the production of iron-polyphenol and its composite material is not particularly limited and may be ordinary water, for example, well water, river / lake water, seawater, tap water, agricultural water, industrial water, deionized water, etc. Distilled water and the like can be mentioned. It may contain a pH buffer, a salt (NaCl, KCl, etc.), an alcohol (ethanol, etc.), a saccharide, an acid, an alkali, etc., as long as it does not interfere with the advantageous effects of the present invention.
鉄−ポリフェノール複合材を製造する装置としては、公知のものを使用できる。容器は、鉄原料と、ポリフェノール源と、水とを均一に混合・撹拌できるものであれば限定されない。反応容器の材質は、ガラス容器、鉄容器、樹脂製容器、いずれも使用可能であるが、加熱や乾燥のための耐熱性を有するものが好ましい。また、酸性や塩基性の溶液に対する耐性を有するものが好ましい。反応時や乾燥時に加熱する装置は、温度制御機能の付いた乾燥機、均一に乾燥するための温風機能、回転機構を有するものがあげられる。乾燥後の鉄−ポリフェノール複合材試料を粉砕するために公知の粉砕機を使用してもよく、粒度を揃えるために適当な篩を使用してもよい。 As an apparatus for producing an iron-polyphenol composite material, a known apparatus can be used.

ポリフェノール源におけるポリフェノールの含有率により、存在できる鉄−ポリフェノールの量が前後するが、意図的に、鉄およびポリフェノールの含有量を減らしたり、または、濃縮した鉄ポリフェノール成分を混在させることにより、鉄−ポリフェノールの含有率を制御することができる。本発明の鉄−ポリフェノール複合材においては、鉄成分は０．１〜２０質量％が好ましく、また、ポリフェノール成分は、０．１〜２０質量％が好ましい。茶などのポリフェノール源のうち、ポリフェノール成分の含有率は原料の茶試料全体の一定の割合であるため、本発明の鉄−ポリフェノール複合材は、鉄−ポリフェノールとその他の茶由来の成分を含有する複合材の形で得られる。例えば、製造した鉄−茶ポリフェノール複合体のうち、５質量％が鉄−茶ポリフェノールであった場合、残りの９５％が茶由来のポリフェノール以外の成分であってもよく、また、残りの成分に未反応の鉄やポリフェノールが存在していてもよいが好ましくは、原料に含まれるポリフェノールに適した比率で鉄が含まれることが好ましい。また、鉄−ポリフェノール複合材を含有する消臭剤には、消臭剤としての効果に影響しない範囲で、他の成分を混合して含有することができる。そのため製造の後工程で珪砂や土、木くずなどの担体と混合してもよい。 The amount of iron-polyphenols that can be present varies depending on the content of polyphenols in the polyphenol source, but by intentionally reducing the content of iron and polyphenols or by mixing concentrated iron polyphenol components, iron- The content of polyphenols can be controlled. In the iron-polyphenol composite material of the present invention, the iron component is preferably 0.1 to 20% by mass, and the polyphenol component is preferably 0.1 to 20% by mass. Since the content of the polyphenol component in the polyphenol source such as tea is a constant ratio of the whole tea sample of the raw material, the iron-polyphenol composite material of the present invention contains iron-polyphenol and other tea-derived components. Obtained in the form of a composite material. For example, when 5% by mass of the produced iron-tea polyphenol complex is iron-tea polyphenol, the remaining 95% may be components other than tea-derived polyphenols, and the remaining components may be Unreacted iron or polyphenol may be present, but it is preferable that iron is contained in a ratio suitable for the polyphenol contained in the raw material. Further, the deodorant containing the iron-polyphenol composite material may contain a mixture of other components as long as the effect as the deodorant is not affected. Therefore, it may be mixed with a carrier such as silica sand, soil, or wood chips in a post-production process.

[Examples 2 to 5, Comparative Examples 2-1 to 5-3]
As the malodorous component, the deodorizing effect on each of the following malodorous components was tested in the same manner as in Example 1 except that the ammonia in Example 1 was replaced with the following malodorous component.
Malodorous components of Examples:
Example 2: Trimethylamine (rotten smell of fish)
Example 3: Acetaldehyde (pungent bluish odor)
Example 4: Methyl mercaptan (rotten onion odor, manure odor)
Example 5: Acetic acid (vinegar, sweat odor)
Comparative Examples 2-1 to 5-3: In the same manner as in Comparative Examples 1-1 to 1-3, nothing was added to the malodorous components of the above Examples, and dried tea leaves were added. Those to which iron (II) sulfate was added were tested (there is no comparative example of only iron (II) sulfate of acetaldehyde).
The detector tubes used were of the model: ammonia 3M (for trimethylamine), methyl mercaptan 71, acetaldehyde 92, and acetic acid 81, respectively.
The results are summarized in Tables 2 to 5.
上記の結果より、茶殻をポリフェノール源として製造した鉄−ポリフェノール複合材は、悪臭成分に対する消臭効果が確認できた。本発明の鉄−ポリフェノール複合材は、比較例の、茶殻のみ、または、鉄化合物のみを用いたものと同等またはそれ以上の消臭効果があることを確認できた。 From the above results, it was confirmed that the iron-polyphenol composite material produced using tea leaves as a polyphenol source had a deodorizing effect on malodorous components. It was confirmed that the iron-polyphenol composite material of the present invention has a deodorizing effect equal to or higher than that of the comparative example using only the tea leaves or only the iron compound.
本発明の鉄−ポリフェノール複合材を含有する消臭剤は、悪臭成分に対し優れた消臭効果を有しており、また、本発明の消臭剤を用いることにより、気体中の悪臭成分を効果的に取り除くことが可能な消臭方法を提供することができる。 The deodorant containing the iron-polyphenol composite material of the present invention has an excellent deodorizing effect on malodorous components, and by using the deodorant of the present invention, the malodorous components in the gas can be removed. It is possible to provide a deodorizing method that can be effectively removed.
