一次仕込みを次のように行った。米麹は、通常の芋焼酎の製造において使用される一般的な焼酎黒麹菌(河内菌黒麹NK)を用い、常法にしたがって製麹した。具体的には、精白された米を、焼酎用黒麹自動ドラム型製麹機を用いて製麹し、42~48時間後に出麹して、米麹を得た。約18kL容のタンクに米麹6t及び水7.2kLを加え、焼酎用酵母(鹿児島酵母2号)を、酵母数が最終濃度で105cell/mLとなるように添加して仕込み、常温にて約5日間発酵を行った。一次発酵を終了した一次醪の総量は約12~13kLとなった。
実施例1で製造した本発明品の官能評価を、既存の芋焼酎(市販品)との比較において実施した。既存の芋焼酎は12銘柄(B~Mと表す)を用いた。訓練された専門のパネラー3名が、芋の香り(焼いた芋のような香ばしい香り~ふくよかな芋の香り)及び味わい(濃厚な味わい~キレのある味わい)について評価し、味わいマップを作成した(図1)。
実施例1で製造した本発明品について成分分析を行った。比較として、既存の芋焼酎(市販品)についても、同様に分析した。本試験において用いた既存品は、試験例1で用いた12銘柄(B~M)に、更に8銘柄(N~R、T、V、及びWと表す)を加えた20銘柄であった(表1)。B~R及びTの18銘柄は一般的な焼酎で、V及びWの2銘柄はハナタレの焼酎である。
エステル成分の分析
分析試料は次のようにして調製した。測定試料(本発明品、既存品20銘柄)(1000μl)を、分析用のバイアル(2ml容)に分注した後、バイアルを密閉・混合した。一方、フェニルエチルアルコールを60%エタノール水溶液に溶解した溶液(500μl)をバイアルに分注した後、バイアルを密閉・混合し、標準試料を作成した。これら試料のエステル成分ないしフェニルエチルアルコールを本明細書に示した方法に従って分析した。
分析試料は次のようにして調製した。測定試料(本発明品ないし既存品20銘柄)(1000μl)を、分析用のバイアル(2ml容)に分注した後、バイアルを密閉・混合した。一方、フルフラールを60%エタノール水溶液に溶解した溶液(500μl)をバイアルに分注した後、バイアルを密閉・混合し、標準試料を作成した。これら試料の脂肪酸成分ないしフルフラールを本明細書に示した方法に従って分析した。
分析試料は次のようにして調製した。測定試料(本発明品ないし既存品20銘柄)(1000μl)を、分析用のバイアル(2ml容)に分注した後、バイアルを密閉・混合した。一方、ゲラニオールを60%エタノール水溶液に溶解した溶液(500μl)をバイアルに分注した後、バイアルを密閉・混合し、標準試料を作成した。これら試料のモノテルペン系成分ないしゲラニオールを本明細書に示した方法に従って分析した。
発明品は、既存の芋焼酎に比べて、ゲラニオール濃度が高いことが示された(図2)。一方、発明品は、既存品に比べて、フルフラールとフェニルエチルアルコールの濃度が低いことが見出された(表1)。一般的な焼酎だけでなく、ハナタレに対しても違いがあることが見出された。
上記の試験において、本発明品に特徴的であることが判明した成分の風味への影響を確認した。
実施例1において作成した芋焼酎(発明品)に、フルフラールとフェニルエチルアルコールをそれぞれ表2に示す濃度になるように添加し、試料を調製した。
5:ふくよかな芋の香りが非常に感じられる
4:ふくよかな芋の香りがよく感じられる
3:ふくよかな芋の香りが感じられる
2:ふくよかな芋の香りがわずかに感じられる
1:ふくよかな芋の香りが感じられない
ゲラニオール濃度が一般的に低いと考えられた既存の芋焼酎を用いて試験を実施した。そのような芋焼酎として焼酎S(ゲラニオール濃度20ppb)を用いた。これにゲラニオールを表3に示す濃度になるように添加し、試料を調製した。各試料のふくよかな芋の香りについて、前述(1)に示した条件に従って官能評価を実施した。
実施例1とは別に、本発明品を製造した。実施例1に記載の方法に従って、本発明品(芋焼酎(アルコール度数25%))を製造した。試験例2に記載の方法(モノテルペン系成分の分析)に従って、本発明品のゲラニオール濃度を測定した。比較として、既存の芋焼酎(B、F、H、I、J、K、L、N、Q、S)についても、同様に測定した。その結果、本発明品は、既存の芋焼酎に比べて、ゲラニオール濃度が高いことが確認された(表4)。
留液のアルコール度数が芋焼酎の風味に及ぼす影響について検討した。
・画分1~14を等量で混合し、全体のアルコール度数が36%の原酒1を得た。
・画分1~13を等量で混合し、全体のアルコール度数が38%の原酒2を得た。
・画分1~12を等量で混合し、全体のアルコール度数が40%の原酒3を得た。
・画分1~10を等量で混合し、全体のアルコール度数が45%の原酒4を得た。
・画分1~7を等量で混合し、全体のアルコール度数が50%の原酒5を得た。
・画分1~4を等量で混合し、全体のアルコール度数が55%の原酒6を得た。
・画分1~2を等量で混合し、全体のアルコール度数が60%の原酒7を得た。
5:キレ、ふくよかな芋の香りが非常に感じられる
4:キレ、ふくよかな芋の香りがよく感じられる
3:キレ、ふくよかな芋の香りが感じられる
2:キレ、ふくよかな芋の香りがわずかに感じられる
1:キレ、ふくよかな芋の香りが感じられない
