Description

この発明は、唐辛子からカプシノイド化合物を低コストでかつ効率良く抽出する抽出分離方法に関する。   The present invention relates to an extraction and separation method for efficiently extracting a capsinoid compound from chili at low cost.

唐辛子には辛味成分であるカプシノイド化合物(カプサイシン等)が含まれている。近年、カプシノイド化合物は抗酸化性、抗菌性等の様々な機能を有していることが報告されている。具体的には、例えばカプシノイド化合物を摂取することで体脂肪燃焼による肥満防止効果や抗酸化作用による老化防止の効果が得られることが知られている。このようにカプシノイド化合物は様々な効用を有して有用であることから、唐辛子から抽出されたカプシノイド化合物の需要は近年急激に増大している。   The chili contains a capsinoid compound (capsaicin or the like) which is a pungent component. In recent years, it has been reported that capsinoid compounds have various functions such as antioxidant and antibacterial properties. Specifically, it is known that, for example, by taking a capsinoid compound, an obesity preventing effect by burning body fat and an aging preventing effect by antioxidant action can be obtained. Thus, since the capsinoid compound is useful with various effects, the demand for the capsinoid compound extracted from the chili pepper has increased rapidly in recent years.

従来、唐辛子からカプシノイド化合物を抽出する方法としては、唐辛子粉砕物と、水、アセトン、アルコール類、ヘキサン、エーテル及びジオキサンからなる群より選ばれる抽出溶媒とを接触させることによって、抽出溶媒中に唐辛子の中のカプシノイド化合物を抽出する方法が公知である(特許文献1参照)。この方法により唐辛子からカプシノイド化合物を容易に抽出分離することができる。
特開2004−66227号公報(請求項12)

第1発明に係る唐辛子からカプシノイド化合物を抽出分離する方法は、唐辛子粉砕物と、水及びアセトンを含有してなる混合抽出溶媒とを接触させることによって、該混合抽出溶媒中に唐辛子中のカプシノイド化合物を抽出分離する方法であり、前記混合抽出溶媒として、水とアセトンの混合モル比が、水/アセトン=95/5〜0.1/99.9の範囲に設定された混合抽出溶媒を用いることを特徴とする。この抽出分離方法によれば、唐辛子からカプシノイド化合物(カプサイシン等)を抽出するに際し、抽出溶媒として、水及びアセトンを含有してなる混合抽出溶媒を用いるから、低コストで且つ高い抽出効率でカプシノイド化合物を抽出することができる。即ち、水及びアセトンを含有してなる混合抽出溶媒を用いることで特異的な抽出挙動が発現して抽出効率を高めることができると共に、非常に安価な水を抽出溶媒として併用することでコストを大きく低減することが可能となる。   The method of extracting and separating a capsinoid compound from a chili according to the first invention comprises contacting a chili pulverized product with a mixed extraction solvent containing water and acetone to bring the capsinoid compound in the chili into the mixed extraction solvent. As a mixed extraction solvent, a mixed extraction solvent in which a mixing molar ratio of water and acetone is set in a range of water / acetone = 95/5 to 0.1 / 99.9 is used. It is characterized by. According to this extraction and separation method, when a capsinoid compound (capsaicin or the like) is extracted from chili, a mixed extraction solvent containing water and acetone is used as an extraction solvent. Therefore, the capsinoid compound is low in cost and high in extraction efficiency. Can be extracted.

It can be greatly reduced.

図1は、水及びアセトンからなる混合抽出溶媒におけるアセトンのモル分率とカプサイシン抽出量との関係を調べたグラフであるが、このグラフから、アセトン(グラフではアセトンのモル分率が1のケースに相当する)はカプサイシンをある程度抽出できるのに対し、水(グラフではアセトンのモル分率が0のケースに相当する)はカプサイシンを殆ど抽出しないことがわかる。このような2つの溶媒(アセトン・水)を混合して混合抽出溶媒とした場合、その混合モル比率を変化させていった時のグラフは一般的には図1の破線のようになると推定される。実際その他の多くの混合溶媒系ではこのようになることが知られている。しかしながら、唐辛子からカプシノイド化合物を溶媒で抽出するに際し、水及びアセトンからなる混合溶媒系では、図1の実線で示すように、一般的な予測曲線(破線)で求められる抽出量よりも格段に多くの量のカプサイシンを抽出できることがわかった。即ち、唐辛子からカプシノイド化合物を溶媒で抽出するに際し、抽出溶媒として、水及びアセトンを含有してなる混合抽出溶媒を用いた場合には図1の実線で示すような特異的な抽出挙動を示して高い抽出効率でカプシノイド化合物を抽出することができるのである。   FIG. 1 is a graph in which the relationship between the molar fraction of acetone and the amount of capsaicin extracted in a mixed extraction solvent composed of water and acetone is examined. From this graph, acetone (the case where the molar fraction of acetone is 1 in the graph) is shown. It can be seen that capsaicin can be extracted to some extent, while water (corresponding to the case where the molar fraction of acetone is 0 in the graph) hardly extracts capsaicin. When these two solvents (acetone / water) are mixed to form a mixed extraction solvent, it is estimated that the graph when the mixing molar ratio is changed is generally as shown by the broken line in FIG. The In fact, many other mixed solvent systems are known to do this. However, when extracting capsinoid compounds from chili with a solvent, the mixed solvent system consisting of water and acetone is much more than the extraction amount required by a general prediction curve (dashed line) as shown by the solid line in FIG. It was found that capsaicin could be extracted in the amount of. That is, when extracting a capsinoid compound from chili with a solvent, when a mixed extraction solvent containing water and acetone is used as the extraction solvent, a specific extraction behavior as shown by the solid line in FIG. Capsinoid compounds can be extracted with high extraction efficiency.

前記混合抽出溶媒における水とアセトンの混合モル比は、水/アセトン=95/5〜0.1/99.9の範囲に設定する。水の混合モル比が上記下限を下回ると実質的にコスト低減にならない。一方、水の混合モル比が上記上限を下回ると抽出効率が大きく低下する。   The mixing molar ratio of water and acetone in the mixed extraction solvent is set to a range of water / acetone = 95/5 to 0.1 / 99.9. If the mixing molar ratio of water is below the lower limit, the cost is not substantially reduced. On the other hand, when the mixing molar ratio of water is lower than the above upper limit, the extraction efficiency is greatly reduced.

中でも、前記混合抽出溶媒における水とアセトンの混合モル比は、水/アセトン=90/10〜40/60の範囲であるのが好ましい。アセトン60モル部に対して水を40モル部以上含有させることで抽出コストを十分に低減できると共に、アセトン10モル部に対して水を90モル部以下とすることでカプシノイド化合物の抽出効率をより向上させることができる。   Especially, it is preferable that the mixing molar ratio of water and acetone in the said mixed extraction solvent is the range of water / acetone = 90 / 10-40 / 60. The extraction cost can be sufficiently reduced by containing 40 mol parts or more of water with respect to 60 mol parts of acetone, and the extraction efficiency of capsinoid compounds can be further increased by making water 90 mol parts or less with respect to 10 mol parts of acetone. Can be improved.

なお、十分に大きい抽出効率を確保する点を特に重視すれば、前記混合抽出溶媒における水とアセトンの混合モル比は、水/アセトン=87/13〜1/99の範囲に設定するのが好ましい(図1参照)。   If the point of securing a sufficiently large extraction efficiency is particularly emphasized, the mixing molar ratio of water and acetone in the mixed extraction solvent is preferably set in the range of water / acetone = 87/13 to 1/99. (See FIG. 1).

第1発明では、抽出溶媒として水及びアセトンを含有してなる混合抽出溶媒を用いるが、この発明の効果を阻害しない範囲であれば、水及びアセトン以外のいかなる溶媒を混合使用しても良い。   In the first invention, a mixed extraction solvent containing water and acetone is used as the extraction solvent. However, any solvent other than water and acetone may be mixed and used as long as the effects of the present invention are not impaired.

また、第2発明に係る唐辛子からカプシノイド化合物を抽出分離する方法は、唐辛子粉砕物と、水及びエタノールを含有してなる混合抽出溶媒とを接触させることによって、該混合抽出溶媒中に唐辛子中のカプシノイド化合物を抽出分離する方法であり、前記混合抽出溶媒として、水とエタノールの混合モル比が、水/エタノール=95/5〜0.1/99.9の範囲に設定された混合抽出溶媒を用いることを特徴とする。この抽出分離方法によれば、唐辛子からカプシノイド化合物(カプサイシン等)を抽出するに際し、抽出溶媒として、水及びエタノールを含有してなる混合抽出溶媒を用いるから、低コストで且つ高い抽出効率でカプシノイド化合物を抽出することができる。即ち、水及びエタノールを含有してなる混合抽出溶媒を用いることで特異的な抽出挙動が発現して抽出効率を高めることができると共に、非常に安価な水を抽出溶媒として併用することでコストを大きく低減することが可能となる。   In addition, the method for extracting and separating capsinoid compounds from the chili according to the second aspect of the present invention comprises contacting the chili pulverized product with a mixed extraction solvent containing water and ethanol, so that This is a method for extracting and separating capsinoid compounds, and as the mixed extraction solvent, a mixed extraction solvent in which a mixing molar ratio of water and ethanol is set in a range of water / ethanol = 95/5 to 0.1 / 99.9. It is characterized by using. According to this extraction and separation method, when extracting a capsinoid compound (capsaicin, etc.) from chili, a mixed extraction solvent containing water and ethanol is used as the extraction solvent, so that the capsinoid compound is low in cost and high in extraction efficiency. Can be extracted. In other words, by using a mixed extraction solvent containing water and ethanol, a specific extraction behavior can be expressed and the extraction efficiency can be increased, and the cost can be reduced by using very inexpensive water as an extraction solvent. It can be greatly reduced.

図2は、水及びエタノールからなる混合抽出溶媒におけるエタノールのモル分率とカプサイシン抽出量との関係を調べたグラフであるが、このグラフから、エタノール(グラフではエタノールのモル分率が1のケースに相当する)はカプサイシンをある程度抽出できるのに対し、水(グラフではアセトンのモル分率が0のケースに相当する)はカプサイシンを殆ど抽出しないことがわかる。このような2つの溶媒(エタノール・水)を混合して混合抽出溶媒とした場合、その混合モル比率を変化させていった時のグラフは一般的には図2の破線のようになると推定される。実際その他の多くの混合溶媒系ではこのようになることが知られている。しかしながら、唐辛子からカプシノイド化合物を溶媒で抽出するに際し、水及びエタノールからなる混合溶媒系では、図2の実線で示すように、一般的な予測曲線(破線)で求められる抽出量よりも格段に多くの量のカプサイシンを抽出できることがわかった。即ち、唐辛子からカプシノイド化合物を溶媒で抽出するに際し、抽出溶媒として、水及びエタノールを含有してなる混合抽出溶媒を用いた場合には図1の実線で示すような特異的な抽出挙動を示して高い抽出効率でカプシノイド化合物を抽出することができるのである。   FIG. 2 is a graph in which the relationship between the mole fraction of ethanol and the amount of capsaicin extracted in a mixed extraction solvent composed of water and ethanol is examined. From this graph, ethanol (in the graph, the case where the mole fraction of ethanol is 1) is shown. It can be seen that capsaicin can be extracted to some extent, while water (corresponding to the case where the molar fraction of acetone is 0 in the graph) hardly extracts capsaicin. When two such solvents (ethanol and water) are mixed to form a mixed extraction solvent, it is estimated that the graph when the mixing molar ratio is changed is generally as shown by the broken line in FIG. The In fact, many other mixed solvent systems are known to do this. However, in extracting a capsinoid compound from chili with a solvent, in a mixed solvent system composed of water and ethanol, as shown by the solid line in FIG. It was found that capsaicin could be extracted in the amount of. That is, when extracting the capsinoid compound from chili with a solvent, when a mixed extraction solvent containing water and ethanol is used as the extraction solvent, a specific extraction behavior as shown by the solid line in FIG. Capsinoid compounds can be extracted with high extraction efficiency.

前記混合抽出溶媒における水とエタノールの混合モル比は、水/エタノール=95/5〜0.1/99.9の範囲に設定する。水の混合モル比が上記下限を下回ると実質的にコスト低減にならない。一方、水の混合モル比が上記上限を下回ると抽出効率が大きく低下する。   The mixing molar ratio of water and ethanol in the mixed extraction solvent is set in a range of water / ethanol = 95/5 to 0.1 / 99.9. If the mixing molar ratio of water is below the lower limit, the cost is not substantially reduced. On the other hand, when the mixing molar ratio of water is lower than the above upper limit, the extraction efficiency is greatly reduced.

中でも、前記混合抽出溶媒における水とエタノールの混合モル比は、水/エタノール=90/10〜50/50の範囲であるのが好ましい。エタノール50モル部に対して水を50モル部以上含有させることで抽出コストを十分に低減できると共に、エタノール10モル部に対して水を90モル部以下とすることでカプシノイド化合物の抽出効率をより向上させることができる。   Especially, it is preferable that the mixing molar ratio of water and ethanol in the said mixed extraction solvent is the range of water / ethanol = 90 / 10-50 / 50. The extraction cost can be sufficiently reduced by containing 50 mol parts or more of water with respect to 50 mol parts of ethanol, and the extraction efficiency of capsinoid compounds can be further increased by making water 90 mol parts or less with respect to 10 mol parts of ethanol. Can be improved.

なお、十分に大きい抽出効率を確保する点を特に重視すれば、前記混合抽出溶媒における水とエタノールの混合モル比は、水/エタノール=86/14〜1/99の範囲に設定するのが好ましい(図2参照)。   In addition, if emphasis is particularly placed on ensuring sufficiently high extraction efficiency, the mixing molar ratio of water and ethanol in the mixed extraction solvent is preferably set in the range of water / ethanol = 86/14 to 1/99. (See FIG. 2).

第2発明では、抽出溶媒として水及びエタノールを含有してなる混合抽出溶媒を用いるが、この発明の効果を阻害しない範囲であれば、水及びエタノール以外のいかなる溶媒を混合使用しても良い。   In the second invention, a mixed extraction solvent containing water and ethanol is used as the extraction solvent. However, any solvent other than water and ethanol may be mixed and used as long as the effects of the present invention are not impaired.

前記第1発明および第2発明のいずれにおいても、前記唐辛子粉砕物と混合抽出溶媒の混合比は、唐辛子粉砕物10質量部に対して混合抽出溶媒を50〜300質量部混合するものとするのが好ましい。混合抽出溶媒を50質量部以上混合することでカプシノイド化合物の抽出効率をさらに向上させることができると共に、300質量部以下とすることで、高い濃度のカプシノイド化合物を含有した抽出溶液を得ることができる。   In any of the first and second inventions, the mixing ratio of the pulverized pepper and mixed extraction solvent is such that 50 to 300 parts by weight of the mixed extraction solvent is mixed with 10 parts by weight of the pulverized pepper. Is preferred. The mixing efficiency of the capsinoid compound can be further improved by mixing 50 parts by mass or more of the mixed extraction solvent, and an extraction solution containing a high concentration of capsinoid compound can be obtained by setting it to 300 parts by mass or less. .

The stirring operation is not particularly limited, and examples thereof include stirring with a stirring blade, shaking stirring with a shaker, and stirring with ultrasonic waves.

また、前記抽出操作を行う際の混合抽出溶媒の温度は、抽出効率への影響はあまり無いものの、30〜60℃に設定するのが好ましい。   Moreover, although the temperature of the mixed extraction solvent at the time of performing said extraction operation does not have much influence on extraction efficiency, it is preferable to set to 30-60 degreeC.

前記抽出分離操作を行うための抽出分離装置としては、特に限定されるものではないが、例えば特開2004−66227号公報に記載の装置を挙げることができる。勿論、一般的なミキサー・セトラー装置を用いても良いし、その他の設備を用いても良く、特に限定されない。   The extraction / separation apparatus for performing the extraction / separation operation is not particularly limited, and examples thereof include an apparatus described in JP-A-2004-66227. Of course, a general mixer / settler apparatus may be used, and other equipment may be used, and is not particularly limited.

なお、上記抽出分離方法によって抽出され得るカプシノイド化合物としては、特に限定されるものではないが、例えばカプサイシン、ジヒドロカプサイシン、ノルジヒドロカプサイシン、ホモカプサイシン、ホモジヒドロカプサイシン等が挙げられる。   The capsinoid compound that can be extracted by the extraction and separation method is not particularly limited, and examples thereof include capsaicin, dihydrocapsaicin, nordihydrocapsaicin, homocapsaicin, and homodihydrocapsaicin.

しかして、上記第1発明または第2発明のいずれかの抽出分離方法によって得られたカプシノイド化合物含有抽出溶媒から溶媒を留去することによって唐辛子抽出物(カプシノイド化合物含有)を回収する。この唐辛子抽出物は、粘稠液体又は固形状態(粉体、粒体等)で回収される。このような溶媒蒸発法により回収するのが一般的であるが、特にこの手法に限定されるものではなく、例えば吸着剤(多孔性樹脂等)を用いる吸着法により唐辛子抽出物の回収を行うものとしても良い。また、これら唐辛子抽出物から、各個別成分(カプサイシン、ジヒドロカプサイシン、ノルジヒドロカプサイシン、ホモカプサイシン、ホモジヒドロカプサイシン等)に単離して利用するものとしても良い。   Thus, the chili extract (capsinoid compound-containing) is recovered by distilling off the solvent from the capsinoid compound-containing extraction solvent obtained by the extraction / separation method of the first invention or the second invention. This chili extract is recovered in a viscous liquid or solid state (powder, granules, etc.). Although it is common to collect by such a solvent evaporation method, it is not particularly limited to this method. For example, a chili extract is recovered by an adsorption method using an adsorbent (porous resin or the like). It is also good. Moreover, it is good also as what isolates and uses for each individual component (Capsaicin, dihydrocapsaicin, nordihydrocapsaicin, a homocapsaicin, a homodihydrocapsaicin, etc.) from these pepper extracts.

前記唐辛子抽出物は、様々な用途に利用することが可能であり、例えば防カビ剤、防虫剤、抗菌剤等として好適に用いられる。   The pepper extract can be used for various purposes, and is suitably used as, for example, a fungicide, an insecticide, an antibacterial agent, and the like.

なお、前記第1発明および第2発明のいずれにおいても、唐辛子粉砕物と混合抽出溶媒とを接触させる前に、予め唐辛子粉砕物と水とを接触せしめて唐辛子中の水溶性物質を溶解除去しておいても良い。こうすることによって、カプシノイド化合物含有抽出溶媒や唐辛子抽出物における水溶性物質の含有比率を大きく低減することができ、その分カプシノイド化合物含有抽出溶媒や唐辛子抽出物におけるカプシノイド化合物含有比率を顕著に増大させることができる。   In both the first and second inventions, before bringing the pulverized pepper into contact with the mixed extraction solvent, the pulverized pulverized product is brought into contact with water in advance to dissolve and remove water-soluble substances in the pepper. You can keep it. By doing so, the content ratio of the water-soluble substance in the capsinoid compound-containing extraction solvent and the pepper extract can be greatly reduced, and the capsinoid compound content ratio in the capsinoid compound-containing extraction solvent and the pepper extract is significantly increased accordingly. be able to.
