食品のメイラード反応による褐変物質は、加熱調理中や保存中に、タンパク質のアミノ基が非酵素的に糖と反応し、更にいくつかの化学反応を経て、不可逆な高分子架橋物質が醸成されたものである。近年、生体にも類似する反応が存在し、その反応によって修飾された生体分子の過剰な蓄積が、糖尿病合併症、動脈硬化症、アルツハイマー病、老化、炎症反応など、様々な疾患の原因となっていることが明らかにされつつある。あるいは、上記のように食品中に醸成された成分を摂取することによっても、同様の症状が引き起こされることが報告されている。(例えば、下記非特許文献1、2参照)。このようにタンパク質のアミノ基の糖化に起因して生成する物質を、一般に最終糖化産物(Advanced Glycation Endproducts(以下「AGEs」という。)と称し、このAGEsの生体内での過剰な蓄積を抑制することによって、それに起因する疾患の予防や症状の改善につなげようと考えられている。   The browning substance due to the Maillard reaction of foods, during cooking and storage, the amino group of the protein reacts non-enzymatically with sugar, and through several chemical reactions, an irreversible polymer cross-linking substance was cultivated. Is. In recent years, there are similar reactions in living organisms, and excessive accumulation of biomolecules modified by these reactions causes various diseases such as diabetic complications, arteriosclerosis, Alzheimer's disease, aging, and inflammatory reactions. It is being revealed that Alternatively, it has been reported that the same symptoms are caused by ingesting ingredients brewed in food as described above. (For example, see Non-Patent Documents 1 and 2 below). Substances generated due to glycation of amino groups of proteins are generally referred to as advanced glycation end products (hereinafter referred to as “AGEs”), and excessive accumulation of AGEs in vivo is suppressed. Therefore, it is thought that it will lead to prevention of diseases caused by it and improvement of symptoms.

AGEs生成抑制剤としては、例えば、従来からアミノグアニジン、ピリドキサミン誘導体などが知られている。更に、下記特許文献1には、3−メチル−1−フェニル−2−ピラゾリン−5−オン(エダラボン)が開示されている。また、一旦形成したAGEsの架橋を破壊する物質も検討されており、例えば、N−臭化フェナシルチアゾリウム(PTB)などが知られている。最近では、1,4−ベンゼン−bis[4−メチレンアミノフェノキシイソ酪酸]などの7種の化合物が報告されている(下記特許文献2)。   As AGEs production inhibitors, for example, aminoguanidine, pyridoxamine derivatives and the like are conventionally known. Further, Patent Document 1 below discloses 3-methyl-1-phenyl-2-pyrazolin-5-one (edaravone). In addition, a substance that breaks the crosslinking of AGEs once formed has been studied. For example, N-phenacylthiazolium bromide (PTB) is known. Recently, seven types of compounds such as 1,4-benzene-bis [4-methyleneaminophenoxyisobutyric acid] have been reported (Patent Document 2 below).

上記抽出原料から抽出物を得るための抽出方法としては、特に制限されないが、例えば食品に使用できる手法、溶媒等を用いるものであれば好ましく、従来知られている鰹だし、鰹エキス等の製造のための抽出方法を用いることができる。例えば、抽出原料と抽出溶媒をタンクに入れ、これらを適宜撹拌しながらエキスの抽出を行うバッチ抽出方法などを好ましく利用することができる。抽出溶媒としては、通常の調理・加工において用いられている水や含水アルコールを用いることが好ましい。なお、アルコールの種類は、食品の製造に使用可能なエタノールが好ましい。抽出効率を上げるためには、抽出原料の粉砕大を、3メッシュ以上に揃えることが好ましく、8〜32メッシュに揃えることがより好ましい。また、抽出時の抽出原料の品温を10〜100℃に保ちながら抽出することが好ましく、35〜100℃に保ちながら抽出することがより好ましい。また、含水アルコールないしは含水エタノールを用いる場合、そのアルコール濃度が1〜80%(v/v)であることが好ましく、1〜50%(v/v)であることがより好ましい。   The extraction method for obtaining the extract from the above-mentioned extraction raw material is not particularly limited, but for example, a method using a method that can be used for foods, a solvent, etc. is preferable, and conventionally known soup stock, koji extract and the like are produced. The extraction method for can be used. For example, a batch extraction method in which an extraction raw material and an extraction solvent are placed in a tank and an extract is extracted while stirring them appropriately can be preferably used. As the extraction solvent, it is preferable to use water or hydrous alcohol used in normal cooking and processing. The alcohol is preferably ethanol that can be used for food production. In order to increase the extraction efficiency, it is preferable to arrange the pulverization size of the extraction raw material to 3 mesh or more, and more preferably to 8 to 32 mesh. Moreover, it is preferable to extract keeping the product temperature of the extraction raw material at the time of extraction at 10-100 degreeC, and it is more preferable to extract keeping at 35-100 degreeC. In the case of using hydrous alcohol or hydrous ethanol, the alcohol concentration is preferably 1 to 80% (v / v), and more preferably 1 to 50% (v / v).

抽出物は、上記抽出原料の2種以上を混合もしくは併用して抽出したものを用いてもよく、上記抽出原料の2種以上を用いて別々に調製した抽出エキスを混合したものを用いてもよい。更に、別々の抽出操作で得られた抽出エキスを混合したものを用いてもよい。   The extract may be obtained by mixing or extracting two or more of the above extraction raw materials, or using a mixture of extract extracts prepared separately using two or more of the above extraction raw materials. Good. Furthermore, you may use what mixed the extract obtained by separate extraction operation.

抽出方法としては、以下に説明する多段抽出法、グラジエント抽出法、もしくはドリップ抽出法を用いることがより好ましい。これらの手法により得られた抽出物は従来用いられている手法によって得られた抽出物より、AGEs生成抑制活性に優れ、風味の面においても優れている。   As the extraction method, it is more preferable to use a multistage extraction method, a gradient extraction method, or a drip extraction method described below. Extracts obtained by these methods are superior in AGEs production inhibitory activity and in flavor as compared with extracts obtained by conventional methods.

以下には、多段抽出法について具体的に説明する。   Hereinafter, the multistage extraction method will be described in detail.

多段抽出法とは、アルコール濃度の異なる抽出溶媒を段階的に抽出原料に接触させて抽出を行う抽出方法である。多段抽出法によれば、抽出溶媒への溶解性の異なる成分を含有するエキスを効率よく得ることができる。   The multi-stage extraction method is an extraction method in which extraction is performed by bringing extraction solvents having different alcohol concentrations into contact with an extraction raw material step by step. According to the multistage extraction method, an extract containing components having different solubility in the extraction solvent can be obtained efficiently.

その好ましい態様においては、抽出原料をカラム又はタンクに充填し、含水アルコールのアルコール濃度を変化させながら通液して抽出エキスを得る。これによれば、1つのカラム又はタンクから抽出されるエキスが、異なるアルコール濃度の含水アルコールで抽出されたものの混合物となるので、カラムやタンクの設置数が少なくてすみ、しかも効率よくエキスを得ることができる。アルコール濃度を段階的に変化させて通液するには、複数濃度の含水アルコールを用意しておき、通液する含水アルコールを経時的に切り替える方法等が採用できる。この場合、アルコール濃度が2段階以上の段階的に変化するように通液してエキスを得ることが好ましく、3段階以上がより好ましい。   In the preferred embodiment, the extraction raw material is filled in a column or tank, and the extract is obtained by passing the liquid while changing the alcohol concentration of the hydrous alcohol. According to this, since the extract extracted from one column or tank becomes a mixture of those extracted with hydrous alcohol having different alcohol concentrations, the number of columns and tanks can be reduced, and the extract can be obtained efficiently. be able to. In order to change the alcohol concentration stepwise, liquid alcohol having a plurality of concentrations is prepared, and the water-containing alcohol to be passed can be switched over time. In this case, it is preferable to obtain an extract by passing through the solution so that the alcohol concentration changes in two or more stages, and more preferably three or more stages.

抽出装置としては、高濃度のエキスを得られる点では、カラム式抽出法が好ましく用いられる。また、タンクを用いる場合は、抽出残渣を再度タンクに戻して、異なるアルコール濃度の含水アルコールで抽出してもよく、タンクの出口にメッシュ等を設置し、擬似カラム様に用いても良い。更にまた、2種類以上の抽出原料を使用する場合には、それらをブレンドした後カラム又はタンクに投入する方法と順次原料を投入し多層を作る方法があるが、適宜その方法を選ぶことができる。   As the extraction apparatus, a column type extraction method is preferably used in that a high concentration extract can be obtained. When a tank is used, the extraction residue may be returned to the tank again and extracted with hydrous alcohol having a different alcohol concentration, or a mesh or the like may be installed at the outlet of the tank and used as a pseudo column. Furthermore, when two or more kinds of extraction raw materials are used, there are a method of blending them and then putting them into a column or tank, and a method of sequentially adding raw materials to form a multilayer, and the method can be selected as appropriate. .

上記抽出原料を効率よく、かつ均一にカラム又はタンクに充填するため、適量(好ましくは抽出原料100質量部に対して10〜70質量部、より好ましくは20〜50質量部)の抽出溶媒に抽出原料を混合して充填することが好ましい。この時に用いる抽出溶媒のアルコール濃度は、後の抽出工程で用いる溶媒のアルコール濃度と同じものを用いることが好ましい。   Extraction into an appropriate amount (preferably 10 to 70 parts by mass, more preferably 20 to 50 parts by mass with respect to 100 parts by mass of extraction material) of extraction solvent in order to efficiently and uniformly fill the column or tank with the extraction raw material. It is preferable to mix and fill the raw materials. The alcohol concentration of the extraction solvent used at this time is preferably the same as the alcohol concentration of the solvent used in the subsequent extraction step.

また、抽出効率をより向上させるために、抽出原料を充填したカラム又はタンクを所定の抽出温度で0.1〜5時間、好ましくは0.5〜1時間静置保温してから抽出を開始することが好ましい。抽出操作は、抽出溶媒をカラム又はタンクの上部若しくは下部より通液して行うことができる。   In order to further improve the extraction efficiency, the column or tank filled with the extraction raw material is allowed to stand at a predetermined extraction temperature for 0.1 to 5 hours, preferably 0.5 to 1 hour, and then extraction is started. It is preferable. The extraction operation can be performed by passing the extraction solvent from the top or bottom of the column or tank.

抽出溶媒の通液量は、適宜設定することができるが、通常、抽出原料100質量部に対して、抽出液量として20〜200質量部となるように設定することが好ましく、40〜150質量部となるように設定することがより好ましい。抽出溶媒の通液量が少な過ぎると充分な抽出効率を得ることができず、通液量が多過ぎると得られる抽出エキスの固形分濃度が低くなり、濃縮等に手間がかかるため好ましくない。   The flow rate of the extraction solvent can be set as appropriate, but it is usually preferable to set the extraction solvent amount to 20 to 200 parts by mass with respect to 100 parts by mass of the extraction raw material, and 40 to 150 parts by mass. It is more preferable to set so as to be a part. If the flow rate of the extraction solvent is too small, sufficient extraction efficiency cannot be obtained, and if the flow rate is too large, the solid content concentration of the obtained extract becomes low, which is not preferable because it takes time for concentration and the like.

また、抽出溶媒のカラム又はタンクへの通液速度は、SV=0.1〜3.0h−1が好ましく、SV=0.5〜2.0h−1がより好ましい。通液速度が上記範囲未満では抽出に時間がかかり、上記範囲を超えると抽出効率が悪く、抽出液の固形分濃度が低くなり、濃縮等に手間がかかるため好ましくない。 Moreover, SV = 0.1-3.0h < -1 > is preferable and SV = 0.5-2.0h < -1 > is more preferable as the liquid passing rate of the extraction solvent to the column or tank. If the flow rate is less than the above range, it takes time for extraction, and if it exceeds the above range, the extraction efficiency is poor, the solid content concentration of the extract becomes low, and it takes time to concentrate, which is not preferable.

また、抽出温度は20〜90℃であることが好ましく、20〜60℃であることがより好ましい。抽出温度が上記温度範囲より低い場合は、充分な抽出効率を得ることができず、上記温度範囲より高い場合には、風味の熱による劣化や、エグ味成分や脂肪等の品質の面で好ましくない成分も抽出されるため好ましくない。   Moreover, it is preferable that extraction temperature is 20-90 degreeC, and it is more preferable that it is 20-60 degreeC. When the extraction temperature is lower than the above temperature range, sufficient extraction efficiency cannot be obtained, and when the extraction temperature is higher than the above temperature range, it is preferable in terms of the quality of the flavor and the like such as deterioration due to heat and taste components Since no components are extracted, it is not preferable.

以下には、グラジエント抽出法について具体的に説明する。   Below, the gradient extraction method is demonstrated concretely.

グラジエント抽出法とは、アルコール濃度が連続的に変化するように通液して抽出エキスを得る方法である。なお、抽出原料のカラム又はタンクへの充填や、抽出溶媒の通液条件などは、上記に説明した多段抽出法と同様に行うことができる。グラジエント抽出法によれば、多段抽出法に比べ、水溶性成分及び脂溶性成分をより効率よく抽出でき、かつ、抽出工程がより簡便である。   The gradient extraction method is a method for obtaining an extract extract by passing liquid so that the alcohol concentration continuously changes. The filling of the extraction raw material into the column or tank, the conditions for passing the extraction solvent, and the like can be performed in the same manner as in the multistage extraction method described above. According to the gradient extraction method, the water-soluble component and the fat-soluble component can be extracted more efficiently and the extraction process is simpler than the multistage extraction method.

抽出溶媒のアルコール濃度を低濃度から高濃度へ連続的に変化させる場合には、アルコール初濃度は0(水)〜50%(v/v)が好ましく、0(水)〜20%(v/v)がより好ましい。また、抽出溶媒のアルコール終濃度は、50〜100%(v/v)が好ましく、80〜100%(v/v)がより好ましい。   When the alcohol concentration of the extraction solvent is continuously changed from a low concentration to a high concentration, the initial alcohol concentration is preferably 0 (water) to 50% (v / v), and 0 (water) to 20% (v / v). v) is more preferred. The alcohol final concentration of the extraction solvent is preferably 50 to 100% (v / v), more preferably 80 to 100% (v / v).

一方、抽出溶媒のアルコール濃度を高濃度から低濃度へ連続的に変化させる場合には、アルコール初濃度は50〜100%(v/v)が好ましく、80〜100%(v/v)がより好ましい。また、抽出溶媒のアルコール終濃度は、0(水)〜50%(v/v)が好ましく、0(水)〜20%(v/v)がより好ましい。   On the other hand, when the alcohol concentration of the extraction solvent is continuously changed from a high concentration to a low concentration, the initial alcohol concentration is preferably 50 to 100% (v / v), more preferably 80 to 100% (v / v). preferable. The alcohol final concentration of the extraction solvent is preferably 0 (water) to 50% (v / v), more preferably 0 (water) to 20% (v / v).

抽出装置としてカラムを用い、アルコール濃度に連続的な変化をつけながら通液する場合、抽出溶媒のアルコール濃度へ勾配をかける手段としては特に制限されず、公知の手段を採用することができる。例えば、異なるアルコール濃度を有する2種類の含水アルコールA、B(どちらか一方はアルコール濃度0%(v/v)、すなわち水であってもよい)を用い、それぞれの溶液の流速を調整しながらカラムに通液する方法や、含水アルコールAをカラムに通液しながら、含水アルコールBを含水アルコールAに混合する方法等が挙げられるが、一定の流速で通液することができる点で後者の方法の方が好ましい。   When a column is used as an extraction device and the solution is passed while continuously changing the alcohol concentration, the means for applying a gradient to the alcohol concentration of the extraction solvent is not particularly limited, and known means can be employed. For example, using two kinds of hydrous alcohols A and B having different alcohol concentrations (one of them may be alcohol concentration 0% (v / v), that is, water), while adjusting the flow rate of each solution Examples include a method of passing through a column and a method of mixing water-containing alcohol B with water-containing alcohol A while passing water-containing alcohol A through the column. The method is preferred.

また、連続的にアルコール濃度を変化させる場合には、例えば、異なるアルコール濃度を有する2種類の含水アルコールA、B(どちらか一方はアルコール濃度0%(v/v)、すなわち水であってもよい)を用い、一方を抽出タンク内に投入し、抽出原料とブレンドし、更に攪拌しながら、任意の流速で抽出液を排出・回収し、同時に同じもう一方の含水アルコールを任意の流量で投入することにより可能となる。   In the case of continuously changing the alcohol concentration, for example, two kinds of hydrous alcohols A and B having different alcohol concentrations (either one of which is alcohol concentration 0% (v / v), that is, water) 1) is put into the extraction tank, blended with the extraction raw material, and the extract is discharged and collected at an arbitrary flow rate while stirring, and at the same time, the other water-containing alcohol is added at an arbitrary flow rate. This is possible.

抽出時におけるアルコール濃度の勾配又はアルコール濃度の変化は、風味や呈味のバランス等に応じて適宜設定することができ、高濃度から低濃度へ変化させてもよく、低濃度から高濃度へ変化させてもよい。例えば、香気成分に重点を置いた場合、アルコール濃度を高濃度から低濃度へ変化させることにより、香気成分をより効率的に抽出することができる。具体的には、アルコール初濃度を、好ましくは50〜100%(v/v)、より好ましくは80〜100%(v/v)とし、アルコールの終濃度を、好ましくは0(水)〜50%(v/v)、より好ましくは0(水)〜20%(v/v)とすればよい。   The gradient of alcohol concentration at the time of extraction or the change in alcohol concentration can be set appropriately according to the balance of flavor and taste, etc., and may be changed from high to low, or changed from low to high You may let them. For example, when emphasis is placed on the aroma component, the aroma component can be extracted more efficiently by changing the alcohol concentration from a high concentration to a low concentration. Specifically, the initial alcohol concentration is preferably 50 to 100% (v / v), more preferably 80 to 100% (v / v), and the final alcohol concentration is preferably 0 (water) to 50. % (V / v), more preferably 0 (water) to 20% (v / v).

なお、得られる抽出エキスのアルコール濃度が高すぎると、アルコール除去の手間が余計にかかるため、好ましくは抽出エキスのアルコール濃度が70%(v/v)以下となるように、抽出溶媒のアルコール濃度やカラム又はタンクへの通液量を設定することが好ましい。例えば、抽出溶媒のアルコール初濃度を99%(v/v)、終濃度を0%(v/v)に設定した場合、抽出原料100質量部に対して、50質量部のアルコール濃度99%(v/v)の含水アルコールを、該含水アルコールの通液速度と同じ流速で水を混合しながらカラム又はタンクへ通液して、抽出液100質量部全量を回収することにより、抽出原料100質量部に対してアルコール濃度50%(v/v)の抽出液100質量部を得ることができる。また、抽出原料100質量部に対して、20質量部のアルコール濃度99%(v/v)の含水アルコールを、該含水アルコールの通液速度と同じ流速で水を混合しながらカラム又はタンクへ通液して、抽出液100質量部全量を回収することにより、抽出原料100質量部に対してアルコール濃度20%(v/v)の抽出液100質量部を得ることができる。この時、水の混合流速を任意に設定・変化させることにより、アルコール濃度の濃度変化を任意に設定することができる。   In addition, if the alcohol concentration of the obtained extract is too high, it takes extra time to remove the alcohol. Therefore, the alcohol concentration of the extraction solvent is preferably set so that the alcohol concentration of the extract is 70% (v / v) or less. It is preferable to set the flow rate to the column or tank. For example, when the initial concentration of alcohol in the extraction solvent is set to 99% (v / v) and the final concentration is set to 0% (v / v), the alcohol concentration of 50 parts by mass with respect to 100 parts by mass of the extraction raw material ( v / v) water-containing alcohol was passed through a column or tank while mixing water at the same flow rate as that of the water-containing alcohol, and 100 parts by mass of the extract was recovered to obtain 100 mass of extraction raw material. 100 parts by mass of an extract with an alcohol concentration of 50% (v / v) can be obtained. Further, with respect to 100 parts by mass of the extraction raw material, 20 parts by mass of hydrous alcohol having an alcohol concentration of 99% (v / v) is passed through a column or tank while mixing water at the same flow rate as the hydrous alcohol. And 100 parts by mass of the extraction liquid is collected to obtain 100 parts by mass of the extraction liquid having an alcohol concentration of 20% (v / v) with respect to 100 parts by mass of the extraction raw material. At this time, the concentration change of the alcohol concentration can be arbitrarily set by arbitrarily setting and changing the mixing flow rate of water.

以下には、ドリップ抽出法について具体的に説明する。   Hereinafter, the drip extraction method will be described in detail.

ドリップ抽出法においては、カラム又はタンク等容器に抽出原料を充填し、一定の容積を有する充填層を形成し、その充填層の上部表面に抽出溶媒を滴下して通液する。その際、滴下した抽出溶媒が抽出原料にすみやかに浸透して、充填層の上部表面において液溜されない状態を保ちながら通液することが好ましい。これによれば、容器に充填された抽出原料に抽出溶媒を均一に分散させつつ通液させることができるので、AGEs生成抑制効果が高く、より品質の安定したエキスを得ることができる。   In the drip extraction method, a column or tank or the like is filled with an extraction raw material, a packed bed having a certain volume is formed, and an extraction solvent is dropped onto the upper surface of the packed bed and passed therethrough. At that time, it is preferable that the dropped extraction solvent permeates the extraction raw material promptly and passes through while maintaining a state where no liquid is retained on the upper surface of the packed bed. According to this, since the extraction solvent can be passed through the extraction raw material filled in the container while being uniformly dispersed, the AGEs production suppressing effect is high, and an extract with a more stable quality can be obtained.

抽出溶媒の滴下速度は、充填層の断面積に対して410リットル/h・m以下で滴下することが好ましく、効率、作業性を考慮すると300〜410リットル/h・mで滴下することがより好ましい。 It is preferable that the extraction solvent is dropped at a rate of 410 liter / h · m 2 or less with respect to the cross-sectional area of the packed bed. Considering efficiency and workability, the extraction solvent is dropped at a rate of 300 to 410 liter / h · m 2. Is more preferable.

抽出溶媒の滴下のためには、充填層の上方に備えられた複数のノズルを有するシャワーノズル、又はスプレイノズル等の抽出溶媒滴下口から、シャワー状、噴霧状、液滴状に滴下することが好ましい。また、ノズルを回転させながら滴下することが好ましい。これによれば、抽出溶媒を充填層の上部表面に均一に滴下することができる。   In order to drop the extraction solvent, it may be dropped in the form of a shower, spray, or droplet from an extraction solvent dropping port such as a shower nozzle having a plurality of nozzles provided above the packed bed or a spray nozzle. preferable. Moreover, it is preferable to drop while rotating the nozzle. According to this, the extraction solvent can be uniformly dropped onto the upper surface of the packed bed.

容器としては、カラム又はタンク等を用いることができる。また、容器に充填される抽出原料の流出を防ぎ、且つ、抽出エキスの通過を許容する特性を有するフィルターを用いることもできる。具体的には、ろ紙、ろ布、セラミック、樹脂、ろ過助剤等が挙げられる。フィルターは、充填層の下部表面の全面に接するように容器の下部に配することが好ましい。これによれば、充填層の下部表面において抽出エキスの流出が阻害されることによる抽出溶媒の移動の乱れを引き起こすことがない。   As the container, a column or a tank can be used. A filter having characteristics that prevent the extraction raw material filled in the container from flowing out and allows the extraction extract to pass therethrough can also be used. Specific examples include filter paper, filter cloth, ceramic, resin, filter aid and the like. The filter is preferably disposed in the lower part of the container so as to be in contact with the entire surface of the lower surface of the packed bed. According to this, the movement of the extraction solvent is not disturbed by the outflow of the extraction extract on the lower surface of the packed bed.

また、充填する抽出原料の粉砕大は40メッシュ以下に粉砕したものであることが好ましく、3メッシュ〜32メッシュに粉砕したものであることがより好ましい。40メッシュ以上であると、通液しにくくなり好ましくない。また、3メッシュ以下であると、抽出効率が悪くなり好ましくない。   The pulverized size of the extraction raw material to be filled is preferably pulverized to 40 mesh or less, more preferably pulverized to 3 mesh to 32 mesh. If it is 40 mesh or more, it is difficult to pass the liquid, which is not preferable. Moreover, when it is 3 mesh or less, extraction efficiency worsens and is not preferable.

抽出溶媒としては、水又は含水アルコールを用いることができる。含水アルコールは、そのアルコール濃度が1〜80%(v/v)であることが好ましく、1〜50%(v/v)であることがより好ましい。単一もしくは異なる濃度の含水アルコール又は水を複数回に分けて使用してもよい。また、含水アルコールを滴下後、続けて水を滴下させ所定量まで抽出エキスを回収してもよい。   As the extraction solvent, water or hydrous alcohol can be used. The hydrous alcohol preferably has an alcohol concentration of 1 to 80% (v / v), more preferably 1 to 50% (v / v). A single or different concentration of hydrous alcohol or water may be used in several portions. Moreover, after dripping a hydrous alcohol, water may be dripped continuously and an extract may be collect | recovered to predetermined amount.

抽出溶媒の通液量は、適宜設定することができるが、通常、抽出原料100質量部に対して、抽出液量として50〜250質量部となるように設定することが好ましく、100〜200質量部となるように設定することがより好ましい。抽出溶媒の通液量が少な過ぎると充分な抽出効率を得ることができず、通液量が多過ぎると得られる抽出エキスの固形分濃度が低くなり、濃縮等に手間がかかるため好ましくない。   The flow rate of the extraction solvent can be set as appropriate, but usually it is preferably set to be 50 to 250 parts by mass with respect to 100 parts by mass of the extraction raw material, and preferably 100 to 200 parts by mass. It is more preferable to set so as to be a part. If the flow rate of the extraction solvent is too small, sufficient extraction efficiency cannot be obtained, and if the flow rate is too large, the solid content concentration of the obtained extract becomes low, which is not preferable because it takes time for concentration and the like.

抽出用タンクに鰹節粉1kgを充填し、抽出溶媒としてエタノール濃度が50%(v/v)の含水アルコール6Lを加えて、約85℃で1時間加熱後、ろ過して抽出エキスを回収した。その後、全量が約半分量となるまで濃縮した。プレート殺菌(95〜105℃)を行い、鰹節の抽出物を得た。
<Preparation Example 8> (Batch extraction)
An extraction tank was filled with 1 kg of bonito flour, 6 L of hydrous alcohol having an ethanol concentration of 50% (v / v) was added as an extraction solvent, heated at about 85 ° C. for 1 hour, and then filtered to recover the extract. Then, it concentrated until the whole quantity became about half quantity. Plate sterilization (95-105 ° C.) was performed to obtain an extract of bonito.

[試験例3]
調製例6〜8で得られた各抽出物を試験サンプルとして、実施例1と同様の方法で、抗糖化試験を行った。結果を表3に示す。
[Test Example 3]
The anti-glycation test was conducted in the same manner as in Example 1 using each of the extracts obtained in Preparation Examples 6 to 8 as a test sample. The results are shown in Table 3.

表3に示されるように、各種の抽出方法による鰹節の抽出物により、ウシ血清アルブミンの糖化を抑制する効果が認められた。また、バッチ抽出に比べ、グラジエント抽出やドリップ抽出による抽出物のほうが、抑制効果が高かった。特にグラジエント抽出による抽出物では、抑制効果が顕著に高かった。
As shown in Table 3, the effect of suppressing glycation of bovine serum albumin was recognized by the extract of bonito from various extraction methods. In addition, the extract by gradient extraction or drip extraction was more effective than batch extraction. In particular, in the extract by gradient extraction, the suppression effect was remarkably high.
