また、本明細書において、フライ食品およびフライ様食品をあわせて「フライ(様)食品」と呼ぶ。
本実施形態に係るアセチル化エンドウ澱粉は、アセチル基含有量が1.6質量%超である。
アセチル化澱粉とは、澱粉中のグルコースの有する水酸基等の水素原子が、アセチル基で置換され、エステル化されたものである。
アセチル基含有量とは、乾物換算の澱粉中のアセチル基(CH3CO-)の含有量(質量%)を表すものである。
アセチル基含有量は、食品添加物公定書(厚生労働省消費者庁)第9版(2018)、成分規格・保存基準、「アセチル化アジピン酸架橋デンプン」、「純度試験(2)アセチル基2.5%以下」に従って測定することができる。
また、アセチル化エンドウ澱粉のアセチル基含有量の上限は、食品添加物公定書(厚生労働省消費者庁)、第9版(2018)で定められている範囲以下とすることも好ましく、2.5質量%以下とすることがより好ましい。
また、本発明における「食感」とは、具体的には、フライ(様)食品の衣のサクミ、衣のひき、種物のやわらかさやしっとり感等を表すものとする。また、衣のひきとは、食品を噛んだ時に噛み切りにくい様子を表し、衣のひきが改善される、とは、噛み切りにくさが低減し、歯切れがよくなることを表す。
アセチル化エンドウ澱粉の原料となるエンドウ澱粉は、他の原料由来の澱粉(たとえばコメ澱粉やタピオカ澱粉)と比較して吸水しにくく、膨潤しにくいという性質がある。そのため、フライ(様)食品等に使用することにより、衣の食感を良好とする等の効果を得ることができる。
しかし、このようなエンドウ澱粉をアセチル化することで、もともとのエンドウ澱粉の有する食感を良好とする効果を維持しつつ、老化による食感の低下を抑えることができると考えられる。
エンドウ澱粉は、主にエンドウ豆からタンパク質を抽出した後の副産物として生成される。
エンドウ豆からエンドウ澱粉を製造する方法に制限はなく、適宜公知の方法が用いられる。またエンドウ澱粉は市販のものを用いることもできる。
また、エンドウ澱粉は、フライ(様)食品の保存後の食感を維持する観点から、好ましくは未加工のエンドウ澱粉である。
また、95℃まで加熱中の最高粘度の上限は、フライ(様)食品の保存後も、衣の好ましい食感を維持する観点から、好ましくは3500cP以下、より好ましくは3300cP以下、さらに好ましくは3100cP以下、さらにより好ましくは2900cP以下、よりいっそう好ましくは2700cP以下である。
また同様の観点から、アセチル化エンドウ澱粉のスラリーを、95℃まで加熱した後、95℃で5分間維持し、25℃まで4.5℃/分で冷却する間の、最低粘度の下限は、フライ(様)食品の保存後も、衣の好ましい食感を維持する観点から、好ましくは1270cP以上、よし好ましくは1280cP以上、さらに好ましくは1290cP以上、さらにより好ましくは1300cP以上、より一層好ましくは1320cP以上、さらにまた好ましくは1350cP以上である。
(i)専用のアルミニウム容器にアセチル化エンドウ澱粉と水とを混合し、アセチル化エンドウ澱粉の乾物換算質量濃度が8質量%のスラリーを調製する。
上記アルミニウム容器に専用のパドルを入れ、ラピッドビスコアナライザー(Rapid Visco Analyzer:RVA)にセットする。
(ii)160rpmでの撹拌下で粘度を測定しながら、40℃で1分間維持し、その後、40℃から95℃まで6℃/分の速度で加熱する。
6℃/分の速度で加熱中に粘度が上昇し始めた温度を糊化開始温度(℃)とする。
(iii)95℃で5分間維持した後、25℃まで4.5℃/分で冷却する。
(iv)25℃から95℃まで加熱する過程の最高粘度(cP)および、95℃に達してから25℃まで冷却する過程の最低粘度(cP)を読み取る。
アセチル化エンドウ澱粉中の目開き0.3mmの篩の篩下画分(粒子)の含有量は、アセチル化エンドウ澱粉の取り扱い性をより良好とし、フライ(様)食品の保存後の食感を維持する観点から、アセチル化エンドウ澱粉全体に対して、好ましくは50質量%以上であり、より好ましくは60質量%以上、さらに好ましくは70質量%以上である。また、同様の観点から、アセチル化エンドウ澱粉中の目開き0.3mmの篩の篩下画分の含有量は、アセチル化エンドウ澱粉全体に対して好ましくは100質量%以下であり、より好ましくは99質量%以下である。
本実施形態のアセチル化エンドウ澱粉は、食品用とすることが好ましい。中でも、フライ(様)食品の衣材として用いることがより好ましい。
衣材としては、バッターおよび打ち粉からなる群から選択される1種として用いることが好ましい。
本実施形態のアセチル化エンドウ澱粉をフライ(様)食品の衣材として用いることにより、フライ(様)食品の製造後、保存する場合、フライ(様)食品の食感を維持することができる。

ここでバッター全体とは、水を含んだバッター全量を表す。
