本発明者等は、上記の機能性成分の吸着剤について検討した結果、所謂白土系の粘土或いはその酸処理物が、上記の機能性成分の水溶液或いはアルコール溶液から該機能性成分を有効に吸着し得るという知見を得た。 As a result of examining the adsorbent for the above-mentioned functional component, the present inventors effectively adsorb the functional component from the so-called clay-based clay or its acid-treated product from the aqueous solution or alcohol solution of the above-mentioned functional component. I got the finding that it can be done.

従って、本発明の目的は、動植物から採取される機能性成分の吸着剤を提供することにある。 Therefore, an object of the present invention is to provide an adsorbent for functional components collected from animals and plants.

本発明によれば、レシチン、アスタキサンチン、ケルセチン配糖体、クロロゲン酸及びイソフラボンからなる群より選択される機能性成分の吸着に用いる吸着剤であって、
ジオクタヘドラル型スメクタイト系粘土もしくはその酸処理物からなることを特徴とする吸着剤が提供される。
According to the present invention, it is an adsorbent used for adsorbing a functional component selected from the group consisting of lecithin, astaxanthin, quercetin glycoside, chlorogenic acid and isoflavone.
Provided is an adsorbent characterized by being composed of a dioctahedral type smectite clay or an acid-treated product thereof.

本発明において、吸着剤として用いるジオクタヘドラル型スメクタイト系粘土は、所謂酸性白土と呼ばれ、またその酸処理物は、活性白土と呼ばれている。 In the present invention, the dioctahedral type smectite clay used as an adsorbent is called so-called acid clay, and the acid-treated product thereof is called activated clay.

即ち、本発明の吸着剤では、上記の機能性成分を含む水溶液或いはアルコール溶液に、この吸着剤を添加することにより、該溶液中から、各種の機能性成分を吸着し、単離することができる。 That is, in the adsorbent of the present invention, by adding this adsorbent to an aqueous solution or an alcohol solution containing the above-mentioned functional component, various functional components can be adsorbed and isolated from the solution. can.

また、本発明の吸着剤は、濾過性も高く、吸着処理後の溶液から容易に分離することができる。 In addition, the adsorbent of the present invention has high filterability and can be easily separated from the solution after the adsorption treatment.

実施例1で用いた本発明の吸着剤(酸性白土)の面指数(06)に由来するX線回折チャートである。It is an X-ray diffraction chart derived from the plane index (06) of the adsorbent (acidic clay) of the present invention used in Example 1. 実施例2で用いた本発明の吸着剤(弱酸処理白土)の面指数(06)に由来するX線回折チャートである。6 is an X-ray diffraction chart derived from the surface index (06) of the adsorbent (weak acid-treated white clay) of the present invention used in Example 2. 実施例3で用いた本発明の吸着剤(活性白土)の面指数(06)に由来するX線回折チャートである。It is an X-ray diffraction chart derived from the surface index (06) of the adsorbent (active clay) of the present invention used in Example 3.

<吸着剤>
本発明において、吸着剤として用いるジオクタヘドラル型スメクタイト系粘土は、火山岩や溶岩等が海水の影響下で変成したものと考えられており、主要成分であるジオクタヘドラル型スメクタイトはSiO四面体層−AlO八面体層−SiO四面体層からなり、且つこれらの四面体層と八面体層が部分的に異種金属で同形置換された三層構造を基本構造(単位層)としており、このような三層構造の積層層間には、Ca、K、Na等の陽イオンや水素イオンとそれに配位している水分子が存在している。また、基本三層構造の八面体層中のAlの一部にMgやFe(II)が置換し、四面体層中のSiの一部にAlが置換しているため、結晶格子はマイナスの電荷を有しており、このマイナスの電荷が基本層間に存在する金属陽イオンや水素イオンにより中和されている。
<Adsorbent>
In the present invention, the dioctahedral smectite-based clay used as an adsorbent is considered to be a metamorphic formation of volcanic rocks, lava, etc. under the influence of seawater, and the dioctahedral smectite, which is the main component, is a SiO 4 tetrahedron layer-AlO 6 The basic structure (unit layer) is a three-layer structure consisting of an octahedral layer-SiO 4 tetrahedral layer, and these tetrahedral layers and octahedral layers are partially homozygously replaced with dissimilar metals. Cations and hydrogen ions such as Ca, K, and Na and water molecules coordinated thereto are present between the laminated layers of the layered structure. Further, since Mg and Fe (II) are substituted in a part of Al in the octahedral layer of the basic three-layer structure and Al is substituted in a part of Si in the tetrahedral layer, the crystal lattice is negative. It has an electric charge, and this negative charge is neutralized by metal cations and hydrogen ions existing between the basic layers.

このようなジオクタヘドラル型スメクタイト系粘土は、その結晶構造に由来する特有のX線回折ピークを示し、例えば、X線回折測定において、面指数(06)に由来する回折ピークを2θ=62度(d=1.49〜1.50Å)付近に有している。 Such dioctahedral type smectite clay shows a peculiar X-ray diffraction peak derived from its crystal structure. For example, in X-ray diffraction measurement, the diffraction peak derived from the plane index (06) is 2θ = 62 degrees (d). = 1.49 to 1.50 Å).

かかるスメクタイト系粘土には、酸性白土、ベントナイト、フラーズアース等があり、基本層間に存在する金属陽イオンの種類や量、及び水素イオン量等によってそれぞれ異なる特性を示す。例えば、ベントナイトでは、基本層間に存在するNaイオン量が多く、このため、水に懸濁分散させた分散液のpHが高く、一般に高アルカリサイドにあり、また、水に対して高い膨潤性を示し、さらにはゲル化して固結するという性質を示す。一方、酸性白土では、基本層間に存在する水素イオン量が多く、このため、水に懸濁分散させた分散液のpHが低く、一般に酸性サイドにあり、また、水に対して膨潤性を示すものの、ベントナイトと比較すると、その膨潤性は総じて低く、ゲル化には至らない。 Such smectite-based clay includes acidic clay, bentonite, fraze earth, etc., and exhibits different characteristics depending on the type and amount of metal cations existing between the basic layers, the amount of hydrogen ions, and the like. For example, in bentonite, the amount of Na ions present between the basic layers is large, so that the pH of the dispersion liquid suspended and dispersed in water is high, generally on the highly alkaline side, and has high swelling property with respect to water. In addition, it exhibits the property of gelling and solidifying. On the other hand, in acidic white clay, the amount of hydrogen ions present between the basic layers is large, and therefore the pH of the dispersion liquid suspended and dispersed in water is low, generally on the acidic side, and exhibits swelling property with respect to water. However, as compared with bentonite, its swelling property is generally low, and gelation does not occur.

本発明において、ジオクタヘドラル型スメクタイト系粘土としては、上述した特有のX線回折ピークを示す限り、上記何れのものも使用することができる。
また、ジオクタヘドラル型スメクタイト系粘土は、粘土の成因、産地及び同じ産地でも埋蔵場所(切羽)等によっても相違するが、一般的には、酸化物換算で以下のような組成を有している。
SiO;50〜75質量%
Al;11〜25質量%
Fe;2〜20質量%
MgO;2〜7質量%
CaO;0.1〜3質量%
NaO;0.1〜3質量%
O;0.1〜3質量%
その他の酸化物(TiO等);2質量%以下
Ig−loss(1050℃);5〜11質量%
In the present invention, as the dioctahedral type smectite clay, any of the above can be used as long as it shows the above-mentioned peculiar X-ray diffraction peak.
Further, the dioctahedral type smectite clay differs depending on the origin of the clay, the place of origin, and the place of burial (face) even in the same place of origin, but generally has the following composition in terms of oxide.
SiO 2 ; 50 to 75% by mass
Al 2 O 3 ; 11-25% by mass
Fe 2 O 3 ; 2 to 20% by mass
MgO; 2-7% by mass
CaO; 0.1 to 3% by mass
Na 2 O; 0.1 to 3% by mass
K 2 O; 0.1 to 3% by mass
Other oxides (TiO 2, etc.); 2% by mass or less Ig-loss (1050 ° C.); 5-11% by mass

また、ジオクタヘドラル型スメクタイト系粘土は、産地等によっては、石英等の不純物を多く含んでいることもある。従って、上記のジオクタヘドラル型スメクタイト系粘土を、必要により石砂分離、浮力選鉱、磁力選鉱、水簸、風簸等の精製操作に賦して不純物をできるだけ除去した吸着剤としての用途に供される。 Further, the dioctahedral type smectite clay may contain a large amount of impurities such as quartz depending on the production area and the like. Therefore, the above dioctahedral type smectite clay is used as an adsorbent from which impurities are removed as much as possible by subjecting it to refining operations such as stone sand separation, buoyancy beneficiation, magnetic beneficiation, elutriation, and elutriation, if necessary. ..

本発明においては、上記のジオクタヘドラル型スメクタイト系粘土の中でも基本層間に含まれるアルカリ金属もしくはアルカリ土類金属の含有量が少ないもの、具体的には、酸性白土或いはフラーズアースと呼ばれるものが好適であり、特に5質量%懸濁液での25℃でのpHが6以下のものが、濾過性等の観点から好適に使用される。 In the present invention, among the above-mentioned dioctahedral type smectite clays, those having a small content of alkali metal or alkaline earth metal contained between the basic layers, specifically, those called acidic white clay or fraze earth are preferable. In particular, a suspension having a pH of 6 or less at 25 ° C. in a 5% by mass suspension is preferably used from the viewpoint of filterability and the like.

また、本発明においては、上記のジオクタヘドラル型スメクタイト系粘土の酸処理物も機能性成分の吸着剤として使用することができる。
この酸処理物は、活性白土と称されるものであり、ジオクタヘドラル型スメクタイト系粘土の基本層構造を破壊しない程度に酸処理することにより、Al分やMg分を溶出させたものである。従って、活性白土は、ジオクタヘドラル型スメクタイト系粘土(非酸処理物)と同様、面指数(06)に由来する回折ピークを示し、また比表面積は増大しており、通常、100m/g以上、特に250m/g以上のBET比表面積を有している。また、かかる活性白土は、上記の酸処理によって固体酸点として働くAlやMgが溶出しているため、酸処理されていないものに比して、固体酸量が低くなっている。ところが、有機酸を用いた場合や酸処理の程度を弱くした場合(弱酸処理)は、夾雑物等によって被覆されていた固体酸点が露出するためか、一般に固体酸量が高くなっている。
従って、一般に、ジオクタヘドラル型スメクタイト系粘土(例えば酸性白土)或いはその酸処理物(例えば活性白土、弱酸処理白土)は、Ho≦−3.0の固体酸量が0.01〜0.70mmol/g−dry clay以上の範囲にある。
Further, in the present invention, the acid-treated product of the above dioctahedral type smectite clay can also be used as an adsorbent for functional components.
This acid-treated product is called activated clay, and is obtained by eluting Al and Mg components by acid treatment to the extent that the basic layer structure of dioctahedral type smectite clay is not destroyed. Therefore, the activated clay shows a diffraction peak derived from the surface index (06), similar to the dioctahedral type smectite clay (non-acid treated product), and the specific surface area is increased, usually 100 m 2 / g or more. In particular, it has a BET specific surface area of 250 m 2 / g or more. Further, since Al and Mg which act as solid acid points are eluted in the activated clay by the above acid treatment, the amount of solid acid is lower than that in the untreated clay. However, when an organic acid is used or when the degree of acid treatment is weakened (weak acid treatment), the amount of solid acid is generally high, probably because the solid acid spots covered with impurities are exposed.
Therefore, in general, dioctahedral type smectite clay (for example, acid clay) or its acid-treated product (for example, active clay, weak acid-treated clay) has a solid acid amount of 0.01 to 0.70 mmol / g with Ho ≦ -3.0. It is in the range of −dry clay or higher.

上述した活性白土のBET比表面積や固体酸量は、酸処理の程度によって変動し、スメクタイト系粘土の基本骨格が変動しない範囲内において、酸処理を強く行うと、BET比表面積が増大し、固体酸量は減少していくこととなる。
例えば、非常に弱い酸処理により得られる活性白土として、本出願人による特開2009−072759には、半活性白土と呼ばれる酸処理物がポリ乳酸解重合用触媒として開示されているが、このような半活性白土も本発明では、機能性成分の吸着剤として使用することができる。
The BET specific surface area and the amount of solid acid of the above-mentioned activated clay fluctuate depending on the degree of acid treatment, and if the acid treatment is strongly performed within the range where the basic skeleton of smectite clay does not fluctuate, the BET specific surface area increases and solids. The amount of acid will decrease.
For example, as an active clay obtained by a very weak acid treatment, Japanese Patent Application Laid-Open No. 2009-072759 by the present applicant discloses an acid-treated product called semi-active clay as a catalyst for polylactic acid depolymerization. In the present invention, semi-active clay can also be used as an adsorbent for functional components.

ジオクタヘドラル型スメクタイト系粘土を粗砕、混練して所定濃度の酸水溶液を用いて、所定の条件で酸処理することにより製造される。
酸処理は、酸水溶液中に、夾雑物が取り除かれたジオクタヘドラル型スメクタイト系粘土を投入し、混合攪拌することにより行われる。酸処理に用いる酸水溶液は、特に限定されるものではないが、コスト、環境への影響等の観点から硫酸水溶液が一般に使用される。
It is produced by coarsely crushing and kneading a dioctahedral type smectite clay and treating it with an acid under predetermined conditions using an acid aqueous solution having a predetermined concentration.
The acid treatment is carried out by putting dioctahedral type smectite-based clay from which impurities have been removed into an acid aqueous solution, mixing and stirring. The acid aqueous solution used for the acid treatment is not particularly limited, but a sulfuric acid aqueous solution is generally used from the viewpoint of cost, environmental impact and the like.

酸処理条件は、目的とする活性白土の物性(BET比表面積や固体酸量)に応じて適宜設定すればよく、例えば硫酸水溶液を使用する場合には、原料粘土中に含まれる水分も硫酸水溶液を構成するものとして算出した硫酸水溶液量が、通常、原料粘土100質量部(110℃乾燥物として)当り250〜800質量部、その時の硫酸水溶液の濃度が1〜15質量%程度(弱酸処理)或いは15〜45質量%(一般的な酸処理)になるような条件で酸処理を行えばよい。酸処理にあたっては、必要により加熱することもできる。 The acid treatment conditions may be appropriately set according to the physical properties (BET specific surface area and solid acid amount) of the target active white clay. For example, when an aqueous sulfuric acid solution is used, the water contained in the raw material clay is also the aqueous sulfuric acid solution. The amount of the sulfuric acid aqueous solution calculated as constituting the above is usually 250 to 800 parts by mass per 100 parts by mass of the raw material clay (as a dried product at 110 ° C.), and the concentration of the sulfuric acid aqueous solution at that time is about 1 to 15% by mass (weak acid treatment). Alternatively, the acid treatment may be performed under conditions such that the content is 15 to 45% by mass (general acid treatment). In the acid treatment, it can be heated if necessary.

このような酸処理によって得られる活性白土は、一般に、酸化物換算で、下記の化学組成を有している。
SiO;50〜85質量%
Al;8〜23質量%
Fe;1〜10質量%以下
MgO;1〜5質量%以下
CaO;0.1〜2質量%以下
NaO;0.1〜1質量%
O;0.1〜1質量%
その他の酸化物(TiO等);2質量%以下
Ig−loss(1050℃);4〜9質量%
The activated clay obtained by such acid treatment generally has the following chemical composition in terms of oxide.
SiO 2 ; 50 to 85% by mass
Al 2 O 3 ; 8-23% by mass
Fe 2 O 3 ; 1 to 10% by mass MgO; 1 to 5% by mass CaO ; 0.1 to 2 % by mass Na 2 O; 0.1 to 1% by mass
K 2 O; 0.1 to 1% by mass
Other oxides (TiO 2, etc.); 2% by mass or less Ig-loss (1050 ° C.); 4-9% by mass

このようなジオクタヘドラル型スメクタイト系粘土の酸処理物である活性白土は、酸処理が施されていることに関連して、優れた濾過性を有する。
即ち、酸処理を施していないスメクタイト系粘土(酸性白土)は、基本層の間にNa等のカチオンを含む大きな層間を有しているために、水に対して高い膨潤性を示し、膨潤による微分散化によって濾過性が悪いと考えられている。しかるに、活性白土では、スメクタイト系粘土中の塩基成分の一部が酸と反応し、ある種、水やアルコールなどに対して不溶性のバインダーとなって粒子間を結合するために、溶液中での微分散化が抑制され、優れた濾過性を示すものと考えられる。
The activated clay, which is an acid-treated product of such a dioctahedral type smectite clay, has excellent filterability in relation to the acid treatment.
That is, the smectite-based clay (acidic clay) that has not been subjected to acid treatment has a large layer containing cations such as Na between the basic layers, and therefore exhibits high swelling property with respect to water due to swelling. It is considered that the filterability is poor due to microdispersion. However, in jar, some of the base components in smectite clay react with acid and become a kind of insoluble binder for water, alcohol, etc., so that the particles are bonded to each other in the solution. It is considered that microdispersion is suppressed and excellent filterability is exhibited.

<吸着剤としての使用>

本発明では、かかる機能性成分として、レシチン、アスタキサンチン、ケルセチン配糖体、クロロゲン酸及びイソフラボンが選択される。
<Use as an adsorbent>
The above-mentioned dioctahedral type smectite clay or an acid-treated product thereof is classified into an appropriate particle size (for example, 150 mesh pass) and used as an adsorbent for a functional component.
In the present invention, lecithin, astaxanthin, quercetin glycoside, chlorogenic acid and isoflavone are selected as such functional components.

即ち、上記の機能性成分の採取過程で得られる機能性成分の水溶液或いはエタノール等のアルコール溶液に、上記の吸着剤を投入し、適宜の時間、撹拌することにより、該液中の機能性成分を吸着することができる。さらに、酵素や微生物等を用いての各種の合成反応により得られた上記の機能性成分を含んでいる水溶液或いはエタノール等のアルコール溶液に投入して機能性成分を吸着することもできる。
上記の水溶液或いはアルコール溶液は、機能性成分濃度と吸着剤の使用量に特に制限はないが、好ましくは5質量%以下の希薄溶液であってよく、通常、該溶液100質量部あたり0.001〜25質量部程度の吸着剤を使用すればよい。
吸着後は、公知の手段によりろ過を行い、機能性成分が吸着されている吸着剤を単離することができる。
吸着された機能性成分の放出方法には特に制限がなく、従来公知の溶媒抽出法等により実施される。例えば純水中に投入され、超音波振動等の撹拌操作に供することにより吸着した機能性成分を放出させ、濃縮または溶媒除去することにより機能性成分を回収することができる。
That is, the above-mentioned adsorbent is added to an aqueous solution of the above-mentioned functional component or an alcohol solution such as ethanol obtained in the process of collecting the above-mentioned functional component, and the adsorbent is stirred for an appropriate time to bring the functional component in the liquid. Can be adsorbed. Further, the functional component can be adsorbed by putting it into an aqueous solution containing the above-mentioned functional component obtained by various synthetic reactions using enzymes, microorganisms or the like or an alcohol solution such as ethanol.
The above aqueous solution or alcohol solution is not particularly limited in the concentration of the functional component and the amount of the adsorbent used, but is preferably a dilute solution of 5% by mass or less, and usually 0.001 per 100 parts by mass of the solution. An adsorbent of about 25 parts by mass may be used.
After adsorption, filtration can be performed by a known means to isolate the adsorbent on which the functional component is adsorbed.
The method for releasing the adsorbed functional component is not particularly limited, and is carried out by a conventionally known solvent extraction method or the like. For example, it can be put into pure water and subjected to a stirring operation such as ultrasonic vibration to release the adsorbed functional component, and the functional component can be recovered by concentrating or removing the solvent.

本発明の吸着剤は、特に卵黄レシチン、大豆レシチン及びアスタキサンチンの吸着に特に優れている。
また、一般に酸処理物である活性白土の方が濾過性等の見地から好適にしようされるのであるが、ケルセチン配糖体(ルチン)、大豆イソフラボン(ゲニステイン)に対しては、酸処理されていないジオクタヘドラル型スメクタイト系粘土の方が優れた吸着性を示す。
回収された機能性成分は、その種類に応じて、各種飲料、サプリメント、或いは医薬品などの用途に供される。
The adsorbent of the present invention is particularly excellent in adsorbing egg yolk lecithin, soybean lecithin and astaxanthin.
In general, activated clay, which is an acid-treated product, is more preferably used from the viewpoint of filterability, but quercetin glycoside (rutin) and soy isoflavone (genistein) are acid-treated. No dioctahedral type smectite clay shows better adsorptivity.
The recovered functional ingredients are used for various beverages, supplements, pharmaceuticals, etc., depending on the type.

本発明の優れた効果を、次の実験例により説明する。 The excellent effect of the present invention will be described with reference to the following experimental examples.

(1)X線回折
(株)リガク製RINT―UltimaIV(X線=CuKα線)にて測定した。
(1) X-ray diffraction Measurement was performed by RINT-Ultima IV (X-ray = CuKα-ray) manufactured by Rigaku Co., Ltd.

(2)pH
イオン交換水に吸着剤濃度が5質量%になるように吸着剤粉末を添加し、30分間撹拌した後、東亜ディーケーケー製pHメーターHM−30Rにて測定を行った。
(2) pH
The adsorbent powder was added to the ion-exchanged water so that the adsorbent concentration was 5% by mass, and the mixture was stirred for 30 minutes, and then measured with a pH meter HM-30R manufactured by Toa DKK.

(3)吸着試験
表1に示す機能性成分と溶媒からなる試験溶液を用いて、各成分に対する吸着能を評価した。吸着能は、1gの吸着剤が吸着できる量(mg)とし、下記の方法により測定し、算出した値を表2に示した。
先ず、それぞれの機能性成分を溶媒に溶かし、濃度0.2g/Lの機能性成分溶液を得た。この溶液30gを50ml容量の遠沈管に秤取し、吸着剤1g(対液3.3質量%)を加えて水平振とう式振とう機(アズワン シェイキングバスSB―13)により150rpmで2.5時間振とうした。
次に遠心分離機(日立工機製CR22GIII)により遠心加速度18000rpmで20分処理した液の上澄み液(試料液)を得た。試料液の吸光度を分光光度計(島津製作所製SPECTROPHOTOMETER UV―3600)により測定した。このとき、試験粉末の溶脱塩類等の影響がある場合は、あらかじめ各成分未溶解の溶媒に試験粉末を加えて同様の操作をしたときの吸光度を試料液の吸光度から差し引き、試料液の補正吸光度とした。そして、予め作成した成分濃度と吸光度の関係を示す検量線を用いて試料液の成分残存量を算出し、吸着剤添加前の成分量から差し引いた値を吸着剤の成分吸着量とした。試験はすべて2反復行い、平均値を用いた。
(3) Adsorption test Using the test solution consisting of the functional component and the solvent shown in Table 1, the adsorption ability for each component was evaluated. The adsorptive capacity was set to an amount (mg) that 1 g of the adsorbent could be adsorbed, measured by the following method, and the calculated values are shown in Table 2.
First, each functional component was dissolved in a solvent to obtain a functional component solution having a concentration of 0.2 g / L. Weigh 30 g of this solution into a centrifuge tube having a capacity of 50 ml, add 1 g of an adsorbent (3.3% by mass with respect to the liquid), and use a horizontal shaker (AS ONE Shaking Bath SB-13) at 150 rpm for 2.5. I shook the time.
Next, a supernatant liquid (sample liquid) of the liquid treated with a centrifuge (CR22GIII manufactured by Hitachi, Ltd.) at a centrifugal acceleration of 18,000 rpm for 20 minutes was obtained. The absorbance of the sample solution was measured with a spectrophotometer (SPECTROPHOTOMETER UV-3600 manufactured by Shimadzu Corporation). At this time, if there is an influence of leaching and desalting of the test powder, the absorbance when the test powder is added to the solvent in which each component is undissolved in advance and the same operation is performed is subtracted from the absorbance of the sample solution, and the corrected absorbance of the sample solution is subtracted. And said. Then, the residual amount of the component of the sample solution was calculated using a calibration curve prepared in advance showing the relationship between the component concentration and the absorbance, and the value subtracted from the amount of the component before the addition of the adsorbent was taken as the component adsorbed amount of the adsorbent. All tests were repeated 2 times and the average value was used.
