原料油脂を、減圧下120℃に加熱することにより十分に乾燥させた後、対油0.2質量%のナトリウムメチラートを添加し、減圧下、110℃で0.5時間攪拌しながらエステル交換反応を行った。反応終了後、ナトリウムメチラートを水洗除去し、常法の精製方法に従って、脱色、脱臭処理して、エステル交換油を得た。なお、油脂組成物の原料油脂中の脂肪酸組成は、ガスクロマトグラフ法(AOCS Ce1f-96準拠)により測定した。
油脂組成物に乳化剤(大豆レシチン0.25質量%、グリセリン脂肪酸エステル0.0625質量%、ソルビタン脂肪酸エステル0.0625質量%)、香料を溶解し、分散させて油相を調製した。同時に、水に脱脂粉乳、メタリン酸ナトリウム、乳化剤(ショ糖脂肪酸エステル0.125%)を溶解し、分散させて水相を調製した。次に、水相に油相を加え、60℃~70℃に調温しながら、ホモミキサーにて予備乳化した。予備乳化後、6.0MPaの圧力下で均質化し、85℃、15分のバッチ殺菌を行い、約10℃まで冷却した後、5℃の冷蔵庫にて約18時間エージングした。
実施例10~18と比較例6~10の水中油型乳化物(クリーム)の乳化安定性、粘度、ヒートショック、ホイップ時間、造花性、口溶け・食感について次のように評価を行った。
各クリームを100mlビーカーに60g計量し、品温を20℃に調整し、スリーワンモーター(四枚羽根のプロペラ)にて160rpmで回転させ、クリームが増粘・凝固するまでの時間を測定した。クリームが増粘・凝固するまでの時間が長いほど、乳化安定性が高いことを示す。増粘・凝固するまでの時間は、5分を超えることが好ましい。
各クリームを200mlビーカーに200g計量し、10℃に調温する。B型粘度計(ローターNO.2、60rpm)で測定する。粘度は200mPa・s以下であることが好ましい。
各クリームを200mlビーカーに200g計量し、20℃、25℃の恒温槽にそれぞれ4時間静置する。その後冷蔵庫(庫内温度5℃~10℃)へ移動し、1晩静置した後、10℃に調温してB型粘度計(ローターNO.2、60rpm)で粘度を測定する。粘度の上昇が少ないほど、熱安定性が高いことを示す。粘度の上昇は、20℃保持の場合は当初粘度の2倍以下、25℃保持の場合は当初粘度の3倍以下であることが好ましい。
各クリーム500gに砂糖35gを加え、ホバートミキサー(ホバート・ジャパン株式会社製)を用い、中速2(約120rpm)で十分立て(絞り出しに適した硬さ)になるまでにかかる時間を計測した。ホイップ時間は4~6分の範囲にあることが好ましい。
十分立てにホイップしたクリームを星型の口金をつけて絞りだし、状態を観察して下記のA~Dの5段階で評価した。造花性は、A~Bまでの状態であれば実用上の使用に耐えられる合格判定とする。A、A-の状態であることがより好ましい。
A :なめらかな外観で、エッジがシャープである。
A- :ややウエットな外観で、エッジにやや丸みがある。
B :ややドライな外観で、エッジがシャープである。
C :ウエットな外観で、エッジが崩れる部分がある。
D :ドライな外観でクリームが締まり硬い状態である。
十分立てにホイップしたクリームの口溶け、食感を官能評価により下記のA~Dの5段階で評価した。口溶け・食感は、A~Bまでの状態であれば好ましいと感じられ合格判定とする。Aであることがより好ましい。
A :クリームは適度な硬さで、口中でシャープな融解感があり、後残りがなくすっきりしている。
A- :クリームは適度な硬さで、口中で融解感があり、後残りがない。
B :クリームがソフトで、口中でゆっくり融解し、後残りがない。
C :クリームが軟らかく、口中でグズグズ残るように感じる。
D :クリームが硬く、口中で融解後も油脂が残るように感じる。
