実施例1の酸化処理に付したホップは酸化反応に起因する脂肪酸などを含んでおり、摂取する態様によっては、この不快臭のため快適な摂取が困難であると考えられた。そこで、不快臭の除去を検討した。
実施例1のホップを、60℃で120時間まで加熱反応時間を保持し、酸化処理に付したホップを得た。該獲得物100gに水を1Lとなるように添加し、55℃で1時間攪拌し、水抽出物を得た。
実施例3の水抽出物をスプレードライヤー(日本ビュッヒ社製;B-290)を用いて濃縮したところ、深緑色固形物(水抽出物由来)を得た。

実施例1の方法に従い、ホップペレットを60℃または80℃で酸化処理し、経時的に生成物を採取しHPLCにて測定し、ピーク全体の面積に対するα酸、β酸およびイソα酸のピーク面積の合計のピーク面積比1、および、ピーク全体の面積に対するα酸、β酸およびイソα酸以外(図1Aの矢印A1およびA2で分画される範囲に当たる)のピーク面積比2を算出した。また、実施例2と同様に、未加熱および加熱のいずれのサンプルでも官能評価を実施した。ピーク面積に関する結果は以下の通りであった。

なお、上記ホップ酸化反応産物抽出物濃度はいずれも、α酸、β酸およびイソα酸量として規定した。
実施例4で得られた酸化処理に付したホップの水抽出物(以下、「ホップ酸化反応産物抽出物」という:α酸、β酸、イソα酸のHPLCピークの面積値の比率(%)は3%)およびイソフムロン溶液(α酸、β酸、イソα酸のHPLCピークの面積値の比率(%)は100%)を所定の割合で混合して試験サンプルとして用い、以下の(1)~(5)の試験方法にしたがって、含有比の違いによる非アルコール飲料の泡質改善効果を確認した。
なお、本試験では、飲料中のホップ酸化反応産物抽出物およびイソフムロンの合計濃度を50ppm(ホップ酸化反応産物抽出物およびイソフムロンはエキス中の固形分換算濃度)とし、試験サンプルのホップ酸化反応産物抽出物およびイソフムロンの配合比を、100:0、80:20、50:50、20:80または0:100とした。なお、ホップ酸化反応産物抽出物濃度はいずれも、α酸酸化物、イソα酸酸化物およびβ酸酸化物量として規定した。

ホップの酸化の進行とともに、ホップ酸化反応産物に含まれるα酸酸化物・イソα酸酸化物およびβ酸酸化物ならびに7α-TCOIHsの量は増加する。図5にホップを様々な条件で酸化反応に付して得られたホップ酸化反応産物中のα酸酸化物、イソα酸酸化物およびβ酸酸化物の量と、7α-TCOIHs量とをプロットした。
また、ホップ酸化反応産物抽出物中のα酸酸化物、イソα酸酸化物およびβ酸酸化物の量に対する7α-TCOIHsの量は、ホップ酸化反応産物調製時の品種、酸化条件および抽出物の抽出条件によって変動したが、約1.5~20質量%の範囲であった。

実施例10で調整したホップ酸化反応産物抽出物を用いて、その添加量と泡質改善効果との関係を評価した。
試験方法
(1)グラニュー糖6%、クエン酸0.12%(酸度0.12)を溶かした溶液に、飲料中のホップ酸化反応産物抽出物由来のα酸酸化物、イソα酸酸化物およびβ酸酸化物の濃度を1~1000ppmとなるように添加し、飲料溶液27~34とした(表21)。
ガス圧測定法、その他評価方法は実施例7に示した(2)~(5)の手法と同様の手法とした。
α酸酸化物、イソα酸酸化物およびβ酸酸化物の濃度を1~1000ppm(7α-TCOIHsの濃度として0.141~141ppm)の間で添加することにより、濃度依存的に泡量は3~150倍、泡持ち時間は100~120倍以上に増加した。
すなわち、イソα酸酸化物およびβ酸酸化物の濃度が1~1000ppm(7α-TCOIHsの濃度として0.141~141ppm)の範囲において泡質向上効果が示された。外観味覚への影響を鑑みると、泡質(泡の外観、データ示さず)および飲用感が1000ppm(7α-TCOIHsの濃度として141ppm)で低下傾向にあったことから、1~500ppm(7α-TCOIHsの濃度として0.141~70.5ppm)とすることが好ましいと考えられた。また、好ましい苦味が泡感によい影響を与えることや苦味の苦手な需要者にも認容されうることから、10~400ppm(7α-TCOIHsの濃度として0.141~56.4ppm)、さらには50~400ppm(7α-TCOIHsの濃度として7.191~56.4ppm)とすることが好ましいと考えられた。
複数のホップ酸化反応産物抽出物を用意し、7α-TCOIHsの濃度と泡質改善効果を評価した。

すなわち、7α-TCOIHsを0.038~105ppm添加した飲料において、泡質向上効果が示された。
外観味覚への影響を鑑みると、泡質(泡の外観、データ示さず)および飲用感が105ppmで低下傾向にあったことから、飲料中の濃度は80ppm未満とすることがより好ましいと考えられた。
