Description

【0001】
【発明の属する技術分野】
本発明はコーヒー濃縮液の製造方法とコーヒー液の製造方法に関し、詳しくは、コーヒー豆またはコーヒー抽出液中の香気成分を濃縮または回収した香気性に優れたコーヒー濃縮液の製造方法とこれを用いるコーヒー液の製造方法に関する。
【0002】
【従来の技術】
コーヒーの品質の良否には香が重要な要素であることは良く知られており、焙煎コーヒー豆やその抽出液に含まれる香気成分の捕集方法には、多くの方法が報告されている。特に、コーヒー中の香気成分の捕集方法としては、コーヒー液を減圧または常圧下で水蒸気と共に飛散させ、これを冷却凝縮させて捕集する方法が一般的である(例えば、特開平1−202248号公報(特許文献1))。
【0003】
しかし、特許文献1に記載されているように、蒸散した揮発性香気成分の70〜90%は冷却凝縮によって回収されるが、残りの香気成分は気化状態で排出される。このため、特許文献1では香気成分を含んだ気体を、水封式ポンプ内の溶媒で捕集し回収する方法を採用している。
【0004】
【特許文献1】
特開平1−202248号公報
【発明が解決しようとする課題】
しかしながら、回収対象となる抽出液および香気成分を捕集する溶媒の液性は、抽出方法やその他の処理によって変化することが多く、特に抽出液のpHは酸化を始めとする多くの反応によって大きく変化し、必ずしも効率的に香気成分を捕集し濃縮することはできない。また、捕集した香気成分は最終的に濃縮などの処理を施されコーヒー液に戻して混合することが一般的であり、混合時に香気成分を損失しない液性が必要であるため、上記従来技術の方法では不十分である。
【0005】
そこで、本発明の目的は、上記従来技術の有する問題点に鑑みて、コーヒー豆中の香気成分を水蒸気と共に蒸散させ溶媒に導入して捕集するに際して、効率的に香気成分を濃縮するコーヒー濃縮液の製造方法とこれを用いたコーヒー液の製造方法を提供することにある。
【0006】
【課題を解決するための手段】
本発明者は上記課題を解決すべく鋭意検討したところ、蒸留時に供する抽出液と飛散した香気成分を捕集する溶媒において、最適なpHを設定することが必要であることを見出し、本発明を完成した。
【0007】
すなわち、本発明に係るコーヒー濃縮液の製造方法の特徴構成は、焙煎したコーヒー豆から抽出したコーヒー抽出液を加熱して蒸留する工程と、この蒸留工程によって飛散する香気成分を水蒸気と共に冷却して凝集液とし、この凝集液を、pH7を越え9以下に調整した溶媒中にて捕集する工程と、を有することにある。
【0008】
この構成によれば、回収対象となる抽出液および香気成分を捕集する溶媒の液性が安定するため、効率的に香気成分を捕集し濃縮することができる。その結果、コーヒー豆中の香気成分を水蒸気と共に蒸散させ溶媒に導入して捕集するに際して、効率的に香気成分を濃縮するコーヒー濃縮液の製造方法を提供することができた。尚、溶媒のpHが7以下であると、加熱臭や異臭が発生したりすると共に、香気成分の回収が不十分であり、又、pHが9を越えると香気成分が低下して好ましくない。より好ましくは、溶媒のpHが8〜9に調整されることである。
【0009】
前記コーヒー抽出液のpHを5〜6に調整して、これを加熱・蒸留すると共に、前記溶媒中に捕集する凝集液を前記コーヒー抽出液に対して3〜20%とすることが好ましい。
【0010】
この構成によれば、コーヒー抽出液として液性の安定したものを用いるので、香気成分を確実に効率よく濃縮できると共に、得られた凝集液を質、量共に優れたものとすることができ、その後の利用、例えば濃縮コーヒー液への添加などに使用し易くなる。コーヒー抽出液のpHが5未満、および6を越える場合は、いずれも安定して香気成分を蒸留し採取することはできない。香気成分を含む凝集液が、3%未満であると利用に際して効率が悪く、逆に20%を越えると含まれる香気成分が薄くなって好ましくない。捕集する凝集液は、5〜15%であることがより好ましい。尚、本明細書において、%は全て重量%を意味する。
【0011】
更に、本発明に係るコーヒー液の製造方法の特徴構成は、請求項1又は2の濃縮方法により濃縮された香気成分を、コーヒー抽出液に混合することにある。
【0012】
この構成によれば、コーヒー豆中の香気成分を水蒸気と共に蒸散させ溶媒に導入して捕集するに際して、効率的に香気成分が濃縮されたコーヒー濃縮液の製造方法を用いて、香気成分に優れたコーヒー液の製造方法を提供することができる。
【0013】
【発明の実施の形態】
本実施形態に係るコーヒー濃縮液の製造方法は、まずコーヒー豆を通常の条件にて焙煎し、この焙煎したコーヒー豆からコーヒー液を抽出する。本実施形態に使用するコーヒー抽出液は、特に制限されるものではなく、公知の方法で工業的に水または熱水で抽出されたものを使用でき、抽出装置についても特に限定されない。
【0014】
次に、得られたコーヒー抽出液をpH5〜6に調整し、約101kPaの常圧下で加熱して水蒸気と共に香気成分を蒸散させる。調整方法としては、クエン酸や炭酸水素ナトリウム等、食品衛生上添加が認められている酸又はアルカリ剤を使用して行う。コーヒー抽出液のpH調整は、アルカリ剤を添加してもよく、pH調整されたイオン交換水に香気成分を蒸散させるようにしてもよい。発生する蒸気を冷却凝集させた後、これをpH7を越え9以下に調整された溶媒中に導入して香気成分を捕集する。コーヒー抽出液を常圧下で蒸留させる方法は、公知の方法および装置で行えばよく、特に制限されるものではない。
【0015】
上記工程により得られる濃縮液は、蒸留する全コーヒー抽出液に対して通常3〜20%とする。得られた濃縮液は、質・量ともに優れた香気成分を含み、濃縮コーヒー液への添加に供せられると共に、コーヒーの風味を添加する目的で、他の食品に香料としても使用することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing a coffee concentrate and a method for producing a coffee liquid, and more particularly, to a method for producing a coffee concentrate having excellent aroma by concentrating or recovering an aroma component in coffee beans or a coffee extract and using the same. The present invention relates to a method for producing a coffee liquid.
[0002]
[Prior art]
It is well known that incense is an important factor in the quality of coffee, and many methods have been reported for collecting aroma components contained in roasted coffee beans and their extracts. . In particular, as a method for collecting aroma components in coffee, a method is generally used in which a coffee liquid is scattered together with water vapor under reduced pressure or normal pressure, and this is cooled and condensed to collect (for example, JP-A-1-202248). Publication (Patent Document 1)).
[0003]
However, as described in Patent Literature 1, 70 to 90% of the evaporated volatile odor components are recovered by cooling and condensation, while the remaining fragrance components are discharged in a vaporized state. For this reason, Patent Literature 1 employs a method of collecting and collecting a gas containing an aroma component using a solvent in a water-sealed pump.
[0004]
[Patent Document 1]
JP-A-1-202248 [Problems to be Solved by the Invention]
However, the liquidity of the extract to be recovered and the solvent that captures the aroma components often changes depending on the extraction method and other treatments. In particular, the pH of the extract is greatly increased by many reactions including oxidation. It is not always possible to efficiently collect and concentrate fragrance components. Further, it is general that the collected fragrance component is finally subjected to a treatment such as concentration and returned to the coffee liquid to be mixed, and it is necessary to have a liquid property that does not lose the fragrance component at the time of mixing. Is not enough.
[0005]
Accordingly, an object of the present invention is to provide a coffee concentrate that efficiently concentrates aroma components when evaporating the aroma components in coffee beans together with water vapor and introducing them into a solvent to collect the aroma components, in view of the above-mentioned problems of the prior art. An object of the present invention is to provide a method for producing a liquid and a method for producing a coffee liquid using the liquid.
[0006]
[Means for Solving the Problems]
The present inventors have conducted intensive studies to solve the above-mentioned problems, and found that it is necessary to set an optimum pH in an extract to be provided during distillation and a solvent for collecting scattered aroma components. completed.
[0007]
That is, the characteristic configuration of the method for producing a coffee concentrate according to the present invention includes a step of heating and distilling the coffee extract extracted from the roasted coffee beans, and a step of cooling the aroma component scattered by the distillation step together with water vapor. And collecting the aggregated liquid in a solvent adjusted to have a pH of more than 7 and 9 or less.
[0008]
According to this configuration, since the liquidity of the solvent to collect the extract and the fragrance component to be collected is stable, the fragrance component can be efficiently collected and concentrated. As a result, it was possible to provide a method for producing a coffee concentrate that efficiently concentrates the aroma components when evaporating the aroma components in the coffee beans together with water vapor, introducing the aroma components into the solvent, and collecting the aroma components. If the pH of the solvent is 7 or less, a heated odor or an unpleasant odor is generated, and the recovery of the fragrance component is insufficient. If the pH exceeds 9, the fragrance component decreases, which is not preferable. More preferably, the pH of the solvent is adjusted to 8-9.
[0009]
It is preferable that the pH of the coffee extract is adjusted to 5 to 6 and the mixture is heated and distilled, and the aggregation liquid collected in the solvent is 3 to 20% of the coffee extract.
[0010]
According to this configuration, since a coffee extract having a stable liquid property is used, the aroma components can be reliably and efficiently concentrated, and the obtained coagulated liquid can be excellent in both quality and quantity, It becomes easy to use for subsequent use, for example, addition to concentrated coffee liquid. When the pH of the coffee extract is less than 5 or more than 6, it is impossible to stably distill and collect the flavor components. If the concentration of the agglomerated liquid containing the fragrance component is less than 3%, the efficiency of use is poor, and if it exceeds 20%, the fragrance component contained is undesirably thin. It is more preferable that the aggregated liquid to be collected is 5 to 15%. In addition, in this specification, all% means weight%.
[0011]
Further, a characteristic configuration of the method for producing a coffee liquid according to the present invention is to mix a flavor component concentrated by the concentration method of claim 1 or 2 with a coffee extract.
[0012]
According to this configuration, when the fragrance component in the coffee beans is vaporized together with the water vapor and introduced into the solvent to collect the fragrance component, the fragrance component is efficiently concentrated by using a method for producing a coffee concentrate in which the fragrance component is concentrated. The present invention can provide a method for producing a hot coffee liquid.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
In the method for producing a coffee concentrate according to the present embodiment, first, coffee beans are roasted under ordinary conditions, and a coffee liquid is extracted from the roasted coffee beans. The coffee extract used in the present embodiment is not particularly limited, and a coffee extract industrially extracted with water or hot water by a known method can be used, and the extractor is not particularly limited.
[0014]
Next, the obtained coffee extract is adjusted to pH 5 to 6, and is heated under normal pressure of about 101 kPa to evaporate fragrance components together with water vapor. The adjustment is carried out using an acid or an alkali agent that is approved for food hygiene, such as citric acid or sodium hydrogen carbonate. To adjust the pH of the coffee extract, an alkali agent may be added, or the flavor component may be evaporated into ion-exchanged water whose pH has been adjusted. After the generated steam is cooled and agglomerated, it is introduced into a solvent adjusted to have a pH of more than 7 and 9 or less to collect aroma components. The method of distilling the coffee extract under normal pressure may be performed by a known method and apparatus, and is not particularly limited.
[0015]
The concentration of the concentrate obtained by the above process is usually 3 to 20% based on the total coffee extract to be distilled. The resulting concentrate contains an excellent flavor component in both quality and quantity, and can be used as an aroma in other foods for the purpose of adding the flavor of coffee while being added to the concentrated coffee liquid. it can.
[0016]
【Example】
Hereinafter, the present invention will be described in detail based on examples. In addition, the measurement of the fragrance amount by gas chromatography is based on the following measurement conditions.
[0017]
Measuring device: Hitachi gas chromatography G-3000
Column: TC-WAX 0.53 mm x 30 m, manufactured by GL Sciences Corporation
Carrier gas: Helium carrier gas flow rate: 1 ml / min Column temperature: 40 ° C. (5 minutes) → 220 ° C. (heating at 5 ° C./min)
Detector: FID
(Example 1)
1000 g of industrially extracted coffee extract (pH 5.6) was distilled by introducing steam at 100 ° C. under a normal pressure of 101 kPa. The vaporized vapor was condensed by a cooling pipe at 5 ° C., and the condensed vapor was introduced into 10 g of a 3% sodium hydrogencarbonate solution (pH 8.4) to collect uncondensed aroma components. The collected aroma condensate was 5.5% (55 g) of the coffee extract set in the distillation apparatus, and the total amount was 65 g together with the collection solvent.
[0018]
10 ml of the obtained flavor concentrate was collected in a 22-ml vial and sealed. The sealed vial was heated at 80 ° C. for 20 minutes using a gas chromatography autosampler manufactured by Tekmar, sampled, and analyzed by gas chromatography under the above conditions to measure the odor concentration. Table 1 shows the measurement results.
[0019]
(Comparative Example 1)
1000 g of an industrially extracted coffee extract (pH 5.6) was distilled under a normal pressure of 101 kPa by introducing steam at 100 ° C. The evaporated vapor was condensed by a cooling pipe at 5 ° C., and the condensed vapor was introduced into 10 g of a 3% phosphoric acid solution (pH 1.7) in order to collect uncondensed aroma components. Other conditions were the same as in Example 1.
[0020]
(Comparative Example 2)
1000 g of industrially extracted coffee extract (pH 5.6) was distilled by introducing steam at 100 ° C. under a normal pressure of 101 kPa. The evaporated vapor was condensed by a cooling pipe at 5 ° C., and the condensed vapor was introduced into 10 g of a 1% potassium hydroxide solution (pH 12.8) in order to collect uncondensed aroma components. Other conditions were the same as in Example 1.
[0021]
[Table 1]
Figure 2004298065
The odor amount in Table 1 was expressed as the total odor amount for gas chromatography temperatures (40, 41 to 95, 96 to 125, 126 to 210 ° C).
[0022]
The aroma solution collected in Example 1 and Comparative Examples 1 and 2 was added to a coffee extract (28% by weight) concentrated under reduced pressure to prepare a 15% by weight concentrated coffee liquid. The obtained concentrated coffee liquid was diluted with hot water to a drinking concentration (solid content of 1.2% by weight), and a sensory evaluation at 65 ° C. during drinking was performed. Table 2 shows the results.
[0023]
[Table 2]
Figure 2004298065
The scent was evaluated as strong: +, normal: ±, weak:-. The overall evaluation was indicated by good: good, normal: bad, bad, and bad.
[0024]
As shown in Table 2, as a result of the sensory test for each collecting solvent, it was found that Example 1 masked the heating odor peculiar to the reduced-pressure concentrate and had an aroma rich in coffee peculiar aroma. On the other hand, in Comparative Example 1, the overall aroma was small, and in Comparative Example 2, an unpleasant odor was generated due to the addition of alkali, resulting in poor evaluation.
