本発明者らは、ブラジル産アラビカ種の焙煎コーヒー豆から得られたコーヒー抽出液の嗜好性をより一層高めるべく、上記特許文献6に記載の方法で処理したところ、後味のキレは改善されるものの、焙煎コーヒー豆特有の甘い香りが低下してしまうことが判明した。一方、ブラジル産アラビカ種の焙煎コーヒー豆から得られたコーヒー抽出液を上記特許文献5に記載の方法で処理したところ、甘い香りは増強されるものの、後味のキレが依然改善されないことが判明した。
本発明の濃縮コーヒー抽出液は、甘い香りに富む(A)ピラジン類と、後味のキレを低下させる原因物質である(B)グアヤコール類とを含有するが、(B)グアヤコール類の含有量が顕著に低減されている。これにより、本発明の濃縮コーヒー抽出液は、濃縮コーヒー抽出液中の(A)ピラジン類の存在比率が高められ、その結果濃縮コーヒー抽出液の甘い香りが増強されるとともに、後味のキレが改善される。
ここで、(A)ピラジン類とは、2-メチルピラジン、2,5-ジメチルピラジン、2,6-ジメチルピラジン、エチルピラジン、2-エチル-5-メチルピラジン、2-エチル-6-メチルピラジン、2-エチル-3-メチルピラジン、2-エチル-3,5-ジメチルピラジン及び3,5-ジメチル-2-メチルピラジンを包含する概念であり、本発明においてはこれらのうち少なくとも1種を含有すればよい。なお、本発明の濃縮コーヒー抽出液中の(A)ピラジン類の含有量は、上記9種の合計量に基づいて定義される。
また、(B)グアヤコール類とは、グアヤコール、4-エチルグアヤコール及び4-ビニルグアヤコールを包含する概念であり、本発明においてはこれらのうち少なくとも1種を含有すればよい。なお、本発明の濃縮コーヒー抽出液中の(B)グアヤコール類の含有量は、上記3種の合計量に基づいて定義される。
次に、本発明の濃縮コーヒー抽出液の製造方法について説明する。
先ず、原料として使用するコーヒー抽出液を準備する。
コーヒー抽出液は、焙煎コーヒー豆から抽出するか、あるいはインスタントコーヒーの水溶液などから調製することができる。本発明で使用するコーヒー抽出液は、当該コーヒー抽出液100g当たりコーヒー豆を生豆換算で1g以上、更に2.5g以上、特に5g以上使用しているものが好ましい。
焙煎コーヒー豆の焙煎度としては、例えば、ライト、シナモン、ミディアム、ハイ、シティ、フルシティ、フレンチ、イタリアンが例示される。中でも、ライト、シナモン、ミディアム、ハイ、シティが好ましい。
焙煎度を色差計で測定したL値としては、10~35、更に15~25、特に16~25であることが好ましい。なお、本発明においては、焙煎度の異なるコーヒー豆を混合してもよく、また粉砕したものを使用してもよい。
抽出器としては特に限定はなく、加熱可能な釜、攪拌機付釜及び攪拌可能な釜、コーヒーカップへ実質的に懸架可能なペーパー又は不織布の袋状構造体、上部にスプレーノズルを有し下部に実質的にコーヒー豆を固液分離可能な構造体(メッシュやパンチングメタルなど)を有するドリップ抽出器、上部及び下部に実質的にコーヒー豆の固液分離可能な構造体(メッシュやパンチングメタルなど)を有するカラム抽出器等が挙げられる。抽出器に加熱又は冷却可能な構造(例えば、電気ヒーター、あるいは温水、蒸気又は冷水が通液可能なジャケット)を有していても良い。
抽出方法としては、バッチ式抽出法、半バッチ式抽出法、連続式抽出法が挙げられる。バッチ式抽出法又は半バッチ式抽出法の抽出時間は、風味の観点より、10秒~120分が好ましく、更に30秒~40分が好ましい。
蒸留は、香気成分の確保、分離速度等の面から、絶対圧で5~100kPa、好ましくは10~50kPa、より好ましくは10~40kPa、特に好ましくは10~30kPaの減圧下で行うのが望ましい。
蒸留の温度条件としては、香気成分の確保、蒸発速度の確保の観点から、20℃以上が好ましく、30℃以上がより好ましく、35℃以上が更に好ましく、40℃以上が更に好ましく、55℃以上が特に好ましい。また、濃縮コーヒー抽出液の品質維持の観点から、100℃以下が好ましく、80℃以下がより好ましく、70℃以下が特に好ましい。
本発明に用いる多孔質吸着体の種類としては、吸着技術便覧―プロセス・材料・設計―(平成11年1月11日、エヌ・ティー・エス発行、監修者:竹内 雍)に記載されている、炭素質吸着材、シリカ・アルミナ系吸着材、高分子吸着材、キトサン樹脂などが使用できる。中でも、不要物質の効率的除去の観点から、炭素質吸着材が好ましい。
炭素質吸着材としては、不要物質の効率的除去の観点から、粉末状活性炭、粒状活性炭、活性炭繊維が好ましい。
バッチ法としては、濃縮液に、多孔質吸着剤を加え-10~100℃で0.5分~5時間撹拌した後、吸着剤を除去すればよい。処理時の雰囲気としては、空気下、不活性ガス下(窒素ガス、アルゴンガス、ヘリウムガス、二酸化炭素)が挙げられるが、風味の観点より不活性ガス下が好ましい。
カラム通液法としては、吸着カラム内に吸着剤を充填し、濃縮液をカラム下部又は上部から通液させ、他方から排出させる。吸着剤の充填高さL及びD(径)の比L/Dは0.1~10が好ましい。吸着剤のカラム内への充填量は、通液前に吸着カラムに充填できる量であれば良い。吸着カラムは、その上段又は下段の少なくとも1つにメッシュ(網)又はパンチングメタルなどの、実質的に吸着剤が漏れ出さない分離構造体を有していることが好ましい。分離構造体の開口径は、吸着剤の平均粒径より小さければ特に限定されず、好ましくは吸着剤の平均粒径の1/2以下、特に好ましくは1/3以下の目開きが良い。具体的な開口径は、0.1~1000μmが好ましい。
本発明の濃縮コーヒー抽出液は、ソリュブルコーヒー、容器詰コーヒー飲料とするのに好適である。
