Description

【0001】
【発明の属する技術分野】
この発明は、熱水抽出が可能な焙煎コーヒー豆調製品およびその製造方法並びに袋状フィルタ入り焙煎コーヒー豆調製品に関する。
【0002】
【従来の技術】
コーヒー専門店その他の飲食店、または家庭などでコーヒーを抽出する方法を簡略に説明すると、いわゆる焙煎コーヒー豆を購入するか、または生豆をロースターで焙煎し、嗜好に応じて望ましい香味の発現したものを抽出方法に適当な粒径に粗砕し、これを熱水または室温の水などで抽出して水可溶成分抽出液を得るようにしている。
【0003】
焙煎(焙焼とも称される。)工程は、加熱によりコーヒー豆中の自由水および結合水を蒸発させかつ品種特有の香味を発現させる工程であり、約230〜260℃程度に加熱することが一般的である。焙煎工程により、生豆の重量は10数パーセント減少し、熱分解と化学変化と共に、水分等が揮散した豆の内部は多孔質化する。
【0004】
また、粗砕は、嗜好に応じて「こく」を出す場合には細粒とし、または香り(アロマとフレーバー)に重点を置く場合には比較的粗めの粗粒とするが、例えば工業的にインスタントコーヒーを製造する場合は、直径0.1〜1.5mm程度、たとえば粒径約1.5mmの場合は1g当り400個程度にカッテイングした粉粒体から抽出液を得て製造されることが多い。
【0005】
そして、抽出をドリップ法で行なうには、コーヒー特有の芳香と味、および「こく」をできるだけ高濃度に保持するように、先ず少量の熱水で「蒸らし」を行ない、次に粉粒体の全体に均一な温度で熱水が浸透する。このように、適当な速度で注水することは、できるだけ多くの成分を抽出して香りおよび味の良いコーヒーを抽出するために好ましいことである。
【0006】
【発明が解決しようとする課題】
しかし、焙煎コーヒー豆を粗砕した粉粒体は、水分を吸着できる多孔質体であり、かつ油脂成分を含んで疎水性であるから、粉粒体の表面は疎水性の多孔質となり、抽出用の熱水が多孔質の細孔内部まで浸透するには、例えば20秒〜1分程度またはそれ以上の時間を要する。また、細孔内から抜け出た空気が粉粒体を取り巻いた状態、いわゆる泡立ちの状態になると、粉粒体は空気に包まれた状態でなかなか水に接することができず、また水から浮力を受けて水面に浮上し、これでは効率よく抽出を行えない。
【0007】
このような焙煎コーヒー豆粉粒体の簡便でない抽出工程は、粉粒体を透水性の袋状フィルタに収容して、熱水などに浸漬した場合にも同様に起こることであり、その場合には袋状フィルタ全体が熱水の表面に浮上する。
【0008】
空気が溜まり水面に浮上した袋状フィルタは、粉粒体の全体に熱水が浸透してフィルタを含めて比重が1以上になるまで水中に沈まない。
【0009】
そして、焙煎コーヒー豆を粗砕した粉粒体またはこれを収容した袋状フィルタに熱水を注いで抽出を行なう場合には、熱水に充分に浸された状態になるまでの待ち時間が長く、特に、一旦、粉粒体が熱水から浮き上がって水に接し難くなると、短時間に効率よく抽出できないという問題があった。
【0010】
そこで、この発明の課題は、上記した問題点を解決して、粉粒体が熱水から浮き上がり難くし、すなわち熱水中に短時間で沈みやすく、粉粒体の細孔内部まで外部の水が拡散浸透できる状態になり、コーヒー豆の水溶成分が水中に効率よく拡散して抽出できる焙煎コーヒー豆の調製品とし、またそのような調製品の確実な製造方法とすることである。
【0011】
【課題を解決するための手段】
上記の課題を解決するため、この発明においては、未抽出の焙煎コーヒー豆を粗砕した粉粒体の細孔内に可食性液体を充填してなる焙煎コーヒー豆調製品としたのである。
【0012】
上記した焙煎コーヒー豆調製品は、焙煎コーヒー豆を粗砕した粉粒体の細孔内に、可食性の液体が充填されているから、細孔が空隙である焙煎コーヒー豆の粉粒体よりも比重が大きく、抽出時に浸される水などの液体に対して浮き上がり難いものになる。
【0013】
また焙煎コーヒー豆調製品は、水に接した状態で細孔の内部と外部が直ちに液相で連続するから、焙煎コーヒー豆の成分が細孔内から抽出液(水)に拡散しやすくて抽出されやすくなる。
【0014】
また、前記の課題を解決するために、焙煎コーヒー豆調製品に用いる可食性液体としては、水、生乳、加工乳、液状乳製品、乳化剤、甘味料および濃縮コーヒー液からなる群から選ばれる一種以上の可食性液体を採用することが好ましい。
【0015】
このような可食性液体は、いずれも抽出されたコーヒーの嗜好性を高めると共に、抽出時間の短縮化に役立つ。特に、充填する可食性液体が、水や濃縮コーヒー液である場合は、抽出液と同じ成分または濃度差によって抽出時間の短縮化を図ることができ、生乳、加工乳である場合は、コーヒー液にミルクが混ざった状態のものが抽出され、抽出後のミルクの添加を省略または少量化することができる。充填する可食性液体が、液状乳製品、乳化剤、甘味料である場合は、各成分に特有の嗜好を付加することができる。
【0016】
また、前記同様の課題を解決するために、焙煎コーヒー豆調製品を、透水性の袋状フィルタに収容した袋状フィルタ入り焙煎コーヒー豆調製品とすることができる。
【0017】
袋状フィルタ入り焙煎コーヒー豆調製品は、これに熱水などを注いでコーヒーを抽出するときに、フィルタ内に泡が発生しないので、速やかに熱水に充分に浸された状態になり、短時間でフィルタおよび粉粒体が水に沈むので、短時間に効率よく抽出することができる。
【0018】
また、上記の焙煎コーヒー豆調製品を製造するために、未抽出の焙煎コーヒー豆を粉砕し、得られた粉粒体を減圧下に可食性液体と接触させ、次いで常圧にまで昇圧することにより前記粉粒体の細孔内に可食性液体を充填する焙煎コーヒー豆調製品の製造方法を採用することができる。
【0019】
また、上記の焙煎コーヒー豆調製品の製造方法において、粉粒体の細孔内に可食性液体を充填した後、遠心分離または減圧濾過により粉粒体の表面を脱液することを特徴とする焙煎コーヒー豆調製品の製造方法としてもよい。
【0020】
上記のいずれの製造方法においても、粉粒体の細孔内に可食性液体を短時間に効率よく充填することができ、また充填後の粉粒体の表面が脱液されていることにより、粉粒体の流動性は確保されるようになり、適当な量だけ計り取る作業や保存容器、包装容器への収納などの取り扱いが簡単になる。
【0021】
また、上記の焙煎コーヒー豆調製品の製造方法において、未抽出の焙煎コーヒー豆を粉砕し、得られた粉粒体を加圧下に可食性液体と接触させることにより前記粉粒体の細孔内に可食性液体を充填する焙煎コーヒー豆調製品の製造方法とすることが好ましい。
【0022】
このようにすると、焙煎コーヒー豆の粉粒体の細孔内に可食性液体が加圧により効率よく充填される。
【0023】
また、焙煎コーヒー豆調製品の製造方法において、粉粒体の細孔内に可食性液体を充填した後、遠心分離または減圧濾過により粉粒体の表面を脱液する焙煎コーヒー豆調製品の製造方法とすることが好ましい。
【0024】
上記の製造方法においても、粉粒体の細孔内に可食性液体を短時間に効率よく充填することができ、また充填後の粉粒体の表面が脱液されていることにより、前記同様に粉粒体の流動性は確保される。
【0025】
【発明の実施の形態】
この発明に用いる焙煎コーヒー豆は、その品種や焙煎の程度を特に限定することなく、通常、家庭やコーヒー販売店などで市販されている程度の抽出可能な焙煎済みコーヒー豆を使用することができ、浅炒り、中炒り、深炒りの何れであってもよい。
【0026】
焙焼コーヒー豆の粗砕は、粒径を特に限定することなく、細粒から粗粒までの何れであってもよい。しかし、あまり微細に粗砕すると、フィルターに目詰まりするか、フィルタから流出する場合があり、また水の接触通過する速度も遅くなって抽出に長時間を要するので好ましくない。
【0027】
この発明に用いる可食性液体は、焙焼コーヒー豆の粉粒体の細孔内に吸着される可食性のものであればよく、特に親水性の液体は好ましいものである。そのような可食性の液体としては、水、生乳、加工乳、液状乳製品、乳化剤、甘味料および濃縮コーヒー液などが挙げられ、これらを2種以上混合して用いることもできる。
【0028】
加工乳としては、生乳、牛乳、脱脂粉乳などの加工した飲料であり、低脂肪乳や濃厚還元乳などの他、ハーブなどのエキスや香料を添加した液状乳飲料が挙げられる。
【0029】
液状乳製品としては、上記した液状の乳飲料以外のものであり、乳酸飲料、練乳類、低粘度のクリーム(植物性または動物性)などが挙げられる。
【0030】
乳化剤としては、ショ糖エステルその他の食品用の乳化剤(液状)を使用可能である。
【0031】
甘味料としては、ショ糖、ブドウ糖などの糖類、またはスクラロース、アスパルテームなどのショ糖誘導体、エリスリトール、ソルビトールなどの糖アルコールなどが挙げられる。
【0032】
このような可食性液体を粉粒体の細孔内に短時間に製造効率よく充填するには、粉粒体を減圧下に可食性液体に浸漬するなどして接触させ、次いで常圧に戻すことからなるいわゆる減圧含浸法を採用するか、または加圧状態で可食性液体に接触させる、いわゆる加圧含浸法を採用できる。
【0033】
減圧下に含浸する場合の減圧条件としては、0〜0.05MPaであればよく、そのような減圧状態に0.1〜100秒程度保持し、次いで徐々に常圧に戻すようにする。
【0034】
また、加圧状態にする場合には、可食性液体に浸漬した圧力タンク(加圧含浸装置)0.2〜1.0MPa程度の圧力下に0.1〜100秒程度おけばよい。なお、上記以上の加圧も可能であるが、コスト面で実用性を失する。
【0035】
この発明に用いる袋状フィルタは、粉粒体を収容して水中で保持可能であり、かつ透水性のものであれば特にフィルタの材質を限定することなく採用できる。たとえば、不織布や紙、布などが挙げられる。

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roasted coffee bean preparation capable of hot water extraction, a method for producing the same, and a roasted coffee bean preparation containing a bag-shaped filter.
[0002]
[Prior art]
To briefly explain the method of extracting coffee at a coffee specialty store or other restaurant, or at home, purchase so-called roasted coffee beans, or roast green beans with a roaster to obtain a desired flavor according to taste. The expressed product is crushed to a particle size suitable for the extraction method, and this is extracted with hot water or water at room temperature to obtain a water-soluble component extract.
[0003]
The roasting (also referred to as roasting) step is a step of evaporating free water and bound water in coffee beans by heating and developing a variety-specific flavor, and heating to about 230 to 260 ° C. Is common. By the roasting process, the weight of the green beans is reduced by more than 10%, and the inside of the beans, in which water and the like have volatilized, is made porous with thermal decomposition and chemical change.
[0004]
In addition, coarse crushing is carried out in the form of fine grains when producing “koku” according to taste, or relatively coarse coarse grains when emphasizing aroma (aroma and flavor). In the case of producing instant coffee, an extract is obtained from powdered granules cut to about 0.1 to 1.5 mm in diameter, for example, in the case of a particle size of about 1.5 mm, to about 400 per gram. There are many.
[0005]
Then, in order to carry out the extraction by the drip method, first carry out "steaming" with a small amount of hot water so as to maintain the aroma and taste peculiar to coffee and "koku" as high as possible, and then, Hot water permeates at a uniform temperature throughout. Thus, it is preferable to inject water at an appropriate rate in order to extract as many components as possible to extract aroma and tasteful coffee.
[0006]
[Problems to be solved by the invention]
However, the powdered granules obtained by crushing roasted coffee beans are porous bodies that can adsorb moisture, and are hydrophobic including fats and oils, so that the surfaces of the powdered granules become hydrophobic and porous. It takes, for example, about 20 seconds to 1 minute or more for the hot water for extraction to penetrate into the porous pores. Also, if the air that escapes from the pores surrounds the granular material, the so-called bubbling state, the granular material cannot easily come into contact with water while being wrapped in the air, and it also increases buoyancy from water. Receiving and floating on the water surface, extraction cannot be performed efficiently.
[0007]
Such an inconvenient extraction step of the roasted coffee bean powder is that the powder and the powder are stored in a water-permeable bag-shaped filter, and the same occurs when immersed in hot water or the like. , The entire bag-like filter floats on the surface of the hot water.
[0008]
The bag-shaped filter in which air is accumulated and floats on the water surface does not sink in water until the specific gravity including the filter becomes 1 or more because hot water permeates the whole of the granular material.
[0009]
In the case where hot water is poured into a granular material obtained by roughly crushing roasted coffee beans or a bag-like filter containing the same to perform extraction, a waiting time until the roasted coffee beans are sufficiently immersed in the hot water. There is a problem that the extraction cannot be efficiently performed in a short period of time, particularly when the granular material once rises from the hot water and becomes difficult to come into contact with the water.
[0010]
Therefore, an object of the present invention is to solve the above-mentioned problems, to make it difficult for the powder and granules to float out of hot water, that is, to easily sink in hot water in a short time, and to prevent external water from reaching inside the pores of the powder and granules. The present invention is to provide a roasted coffee bean preparation in which water can be diffused and infiltrated, and a water-soluble component of coffee beans can be efficiently diffused and extracted in water, and a method for reliably producing such a roasted coffee bean.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, a roasted coffee bean preparation is prepared by filling an edible liquid in the pores of a granulated material obtained by crushing unextracted roasted coffee beans. .
[0012]
The above-mentioned roasted coffee bean preparation is filled with an edible liquid in the pores of the granules obtained by coarsely crushing the roasted coffee beans. The specific gravity is larger than that of the granules, and it is difficult to lift the liquid such as water immersed at the time of extraction.
[0013]
In addition, in the roasted coffee bean preparation, the inside and outside of the pores are immediately continuous in liquid phase in contact with water, so that the components of the roasted coffee beans easily diffuse into the extract (water) from inside the pores. Easier to extract.
[0014]
In order to solve the above problems, the edible liquid used in the roasted coffee bean preparation is selected from the group consisting of water, raw milk, processed milk, a liquid dairy product, an emulsifier, a sweetener and a concentrated coffee liquid. Preferably, one or more edible liquids are employed.
[0015]
Such edible liquids all contribute to enhancing the palatability of the extracted coffee and shortening the extraction time. In particular, when the edible liquid to be filled is water or a concentrated coffee liquid, the extraction time can be reduced by the same component or concentration difference as the extraction liquid, and when it is raw milk or processed milk, the coffee liquid is used. The milk mixed with the milk is extracted, and the addition of the milk after the extraction can be omitted or reduced. When the edible liquid to be filled is a liquid dairy product, an emulsifier, or a sweetener, a particular taste can be added to each component.
[0016]
Further, in order to solve the same problem as described above, the roasted coffee bean preparation can be a roasted coffee bean preparation containing a bag-like filter housed in a water-permeable bag-like filter.
[0017]
The roasted coffee bean preparation containing the bag-shaped filter, when pouring hot water or the like into it to extract coffee, does not generate bubbles in the filter, so it quickly becomes fully immersed in hot water, Since the filter and the granular material sink in the water in a short time, it can be efficiently extracted in a short time.
[0018]
Further, in order to produce the above-mentioned roasted coffee bean preparation, unextracted roasted coffee beans are pulverized, and the obtained granules are brought into contact with an edible liquid under reduced pressure, and then pressurized to normal pressure. By doing so, it is possible to employ a method for producing a roasted coffee bean preparation in which the edible liquid is filled in the pores of the granular material.
[0019]
Further, in the above method for producing a roasted coffee bean preparation, after filling the edible liquid into the pores of the granular material, the surface of the granular material is drained by centrifugation or vacuum filtration. It may be a method for producing a roasted coffee bean preparation.
[0020]
In any of the above-described production methods, the edible liquid can be efficiently filled in the pores of the granular material in a short time, and the surface of the granular material after the filling is drained, The fluidity of the powder is ensured, and the work of measuring an appropriate amount and storing in a storage container or a packaging container is simplified.
[0021]
Further, in the above-mentioned method for producing a roasted coffee bean preparation, the unextracted roasted coffee beans are pulverized, and the obtained granules are brought into contact with an edible liquid under pressure to reduce the size of the granules. It is preferable to use a method for producing a roasted coffee bean preparation in which edible liquid is filled in the holes.
[0022]
In this way, the edible liquid is efficiently filled into the pores of the roasted coffee beans by pressurization.
[0023]
Further, in the method for producing a roasted coffee bean preparation, after filling the edible liquid into the pores of the granule, the roasted coffee bean preparation is subjected to centrifugation or vacuum filtration to drain the surface of the granule. Is preferred.
[0024]
In the above production method, the edible liquid can be efficiently filled in the pores of the granular material in a short time, and the surface of the granular material after the filling is drained. In addition, the fluidity of the powder is ensured.
[0025]
BEST MODE FOR CARRYING OUT THE INVENTION
The roasted coffee beans used in the present invention are not particularly limited in their varieties and roasting degrees, and usually use extractable roasted coffee beans that are commercially available at home or coffee shops. It can be any of light roast, medium roast and deep roast.
[0026]
The coarse crushing of the roasted coffee beans may be any of fine particles to coarse particles without any particular limitation on the particle size. However, if it is finely crushed, the filter may be clogged or may flow out of the filter, and the speed of contact and passage of water may be low, so that it takes a long time for extraction, which is not preferable.
[0027]
The edible liquid used in the present invention may be any edible liquid adsorbed in the fine pores of the roasted coffee beans, and a hydrophilic liquid is particularly preferable. Such edible liquids include water, raw milk, processed milk, liquid dairy products, emulsifiers, sweeteners, concentrated coffee liquids, and the like, and two or more of these can be used in combination.
[0028]
The processed milk is a processed beverage such as raw milk, cow's milk, skim milk powder, etc., and includes a liquid milk beverage to which an extract such as herbs or a flavor is added in addition to low fat milk and concentrated reduced milk.
[0029]
Liquid dairy products are those other than the above-mentioned liquid milk drinks, and include lactic acid drinks, condensed milks, low-viscosity creams (vegetable or animal).
[0030]
As the emulsifier, a sucrose ester or another emulsifier (liquid) for food can be used.
[0031]
Examples of the sweetener include sugars such as sucrose and glucose, sucrose derivatives such as sucralose and aspartame, and sugar alcohols such as erythritol and sorbitol.
[0032]
In order to fill such edible liquid into the pores of the granular material in a short time with high production efficiency, the granular material is brought into contact with the edible liquid by immersion under reduced pressure or the like, and then returned to normal pressure. Or a so-called pressurized impregnation method in which the edible liquid is brought into contact with an edible liquid in a pressurized state.
[0033]
The pressure reduction conditions for impregnation under reduced pressure may be 0 to 0.05 MPa. Such a reduced pressure state is maintained for about 0.1 to 100 seconds, and then gradually returned to normal pressure.
[0034]
In the case of a pressurized state, a pressure tank (pressurized impregnating apparatus) immersed in an edible liquid may be kept under a pressure of about 0.2 to 1.0 MPa for about 0.1 to 100 seconds. It is to be noted that the above pressurization is possible, but loses practicality in terms of cost.
[0035]
The bag-shaped filter used in the present invention can be used without any particular limitation on the material of the filter as long as the bag-shaped filter can accommodate and hold the granular material in water and is water-permeable. For example, nonwoven fabric, paper, cloth, and the like can be given.
[0036]
【Example】
[Example 1]
The medium roasted roasted coffee beans were coarsely crushed into fine granules to prepare 100 g of powder (particle diameter: 0.1 to 0.3 mm). The powder was stored in a tank of a vacuum impregnating apparatus, pressed with a 100-mesh wire net, and 500 ml of cold water (4 to 5 ° C.) was placed thereon. Then, the pressure was reduced to 0.02 to 0.007 MPa by a vacuum pump, maintained for about 20 seconds, and then gradually returned to normal pressure over 30 minutes.
[0037]
Next, the powder was filtered with a nonwoven fabric and drained, and then centrifuged at a speed of 1000 rpm to remove water on the surface.
[0038]
The obtained roasted coffee bean preparation was put into a commercially available bag-shaped filter formed of filter paper, and this was used as a roasted coffee bean preparation (10 g) containing a bag-shaped filter.
[0039]
[Examples 2 to 4]
Example 1 is the same as Example 1, except that the edible liquid was replaced with cold water, and milk (no component adjustment) (Example 2), condensed milk (Example 3), and sucrose ester (Example 4) were used. To prepare a roasted coffee bean preparation (10 g) containing a bag-shaped filter.
[0040]
[Examples 5 and 6]
The medium roasted roasted coffee beans were coarsely crushed into fine granules to prepare 100 g of powder (particle size: 0.1 to 0.3 mm). The granules were placed in a tank of a pressure impregnation device containing 500 ml of glucose solution (Example 5) or a separately prepared concentrated coffee solution (double concentrated solution) (Example 6), and mixed. The pressure was increased to 0.9 MPa by a pressure pump, maintained for about 20 seconds, and then gradually returned to normal pressure over 1 minute.
[0041]
Next, the granular material was filtered through a nonwoven fabric and drained, and then the surface was dried by a centrifugal separator at a speed of 1000 rpm.
[0042]
The obtained roasted coffee bean preparation was put into a commercially available bag-shaped filter formed of filter paper, and this was used as a roasted coffee bean preparation (9 g) containing a bag-shaped filter.
[0043]
Each of the roasted coffee bean preparations with bag-shaped filters of Examples 1 to 6 was put in a coffee cup, and 150 cc of 98 ° C. hot water was poured. A coffee or coffee beverage with a well extracted flavor could be extracted.
[0044]
