Description

【0001】
【発明の属する技術分野】
本発明は、生クリームのようなみずみずしい食感を有し、特にホイップ用クリームとして好適な水中油型乳化脂に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
牛乳から遠心分離により作られる生クリームは、風味が良好なだけでなく、食感も非常にみずみずしく、既存のどのようなコンパウンドクリームとも比較にならないほど優れている。このためコンパウンドクリームの食感を生クリームに近づけるべく、これまでに様々な試みがなされている。
【0003】
例えば、ラウリン系油脂を70%以上含有する上昇融点が28℃以下の油脂を用い、乳脂肪皮膜タンパク質を0.1重量%以上、乳清ミネラルを0.1重量%以上使用する方法(特許文献1を参照)が提案されており、またカゼイネートと卵黄油との併用(特許文献2を参照)が提案されているが、何れも十分に満足し得るとは言い難いものである。
【0004】
従って、本発明の目的は、生クリームのようなみずみずしい食感を有する水中油型乳化脂を提供することにある。

【課題を解決するための手段】
本発明は、乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料と、乳由来の固形分中の灰分の含有量が10重量%以上である乳原料を含み、乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料が、クリーム又はバターからバターオイルを製造する際に生じる水相成分であり、乳由来の固形分中の灰分の含有量が10重量%以上である乳原料が、乳清ミネラルであることを特徴とする水中油型乳化脂を提供することにより、上記目的を達成したものである。
また、本発明は、上記の本発明の水中油型乳化脂の好ましい製造方法として、乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料と、乳由来の固形分中の灰分の含有量が10重量%以上である乳原料を水性相及び/又は油性相に添加し、該水性相と該油性相とを乳化することを特徴とする水中油型乳化脂の製造方法を提供するものである。
【0007】
【発明の実施の形態】
以下、本発明の水中油型乳化脂について詳細に説明する。
【0008】
本発明の水中油型乳化脂は、乳由来の固形分中のリン脂質の含有量が2重量%以上、好ましくは3重量%以上、さらに好ましくは4重量%以上、最も好ましくは5〜40重量%である乳原料を含むことを特徴とする。乳由来の固形分中のリン脂質の含有量が2重量%未満である乳原料を用いると、生クリームのようなみずみずしい食感が得られない。
上記の乳由来の固形分中のリン脂質とは、乳由来の固形分中に含まれる乳由来のリン脂質のことを示す。
また、上記の乳原料は、液体状でも、粉末状でも、濃縮物でも構わない。但し、溶剤を用いて乳由来の固形分中のリン脂質の含有量が2重量%以上となるように濃縮した乳原料は、風味上の問題から本発明における乳原料として用いないのが好ましい。
【0009】
乳原料のリン脂質の定量方法は、例えば以下のような方法にて測定することができる。但し、抽出方法などについては乳原料の形態などによって適正な方法が異なるためこの定量方法に限定されるものではない。
まず、乳原料の脂質をFolch法を用いて抽出する。図1にFolch法のフローを示す。次いで、抽出した脂質溶液を湿式分解法(日本薬学会編、衛生試験法・注解2000 2.1食品成分試験法に記載の湿式分解法に準じる)にて分解した後、モリブデンブルー吸光度法(日本薬学会編、衛生試験法・注解2000 2.1食品成分試験法に記載のリンのモリブデン酸による定量に準じる)によりリン量を求める。求められたリン量から以下の計算式を用いて乳原料100g中のリン脂質の含有量gを求める。
リン脂質(g/100g)=〔リン量(μg)/乳原料採取量(g)〕×25.4×(0.1/1000)
【0010】
上記の乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料としては、例えば、クリーム又はバターからバターオイルを製造する際に生じる水相成分があげられる。このクリーム又はバターからバターオイルを製造する際に生じる水相成分は、通常のクリームからバターを製造する際に生じるいわゆるバターミルクとは組成が大きく異なり、リン脂質を多量に含有しているという特徴がある。バターミルクは、その製法の違いによって大きく異なるが、乳由来の固形分中のリン脂質の含有量が、通常、0.5〜1.5重量%程度であるのに対して、クリーム又はバターからバターオイルを製造する際に生じる水相成分は、乳由来の固形分中のリン脂質の含有量が、大凡、2〜15重量%であり、多量のリン脂質を含有している。
【0012】
次に上記のクリーム又はバターからバターオイルを製造する際に生じる水相成分の製造方法について説明する。
【0013】
クリームからバターオイルを製造する際に生じる水相成分の製造方法は、例えば以下の通りである。まず、牛乳を遠心分離して得られる脂肪濃度30〜40重量%のクリームをプレートで加温し、遠心分離機によってクリームの脂肪濃度を70〜95重量%まで高める。次いで乳化破壊機で乳化を破壊し、再び遠心分離機で処理することによってバターオイルが得られる。本発明で用いられる上記水相成分は、最後の遠心分離の工程でバターオイルの副産物として発生するものである。
【0014】
一方、バターからバターオイルを製造する際に生じる水相成分の製造方法は、例えば以下の通りである。まずバターを溶解機で溶解し熱交換機で加温する。これを遠心分離機で分離することによってバターオイルが得られる。本発明で用いられる上記水相成分は、最後の遠心分離の工程でバターオイルの副産物として発生するものである。該バターオイルの製造に用いられるバターとしては、通常のものが用いられる。
【0015】
また、本発明で用いられる上記水相成分としては、乳由来の固形分中のリン脂質の含有量が2重量%以上であれば、クリーム又はバターからバターオイルを製造する際に生じる水相成分をそのまま用いてもよく、また噴霧乾燥、濃縮、冷凍などの処理を施したものを用いてもよい。
【0016】
本発明の水中油型乳化脂は、上記の乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料を、固形分として、好ましくは0.1〜7重量%、さらに好ましくは0.5〜5重量%、最も好ましくは1〜4重量%含有するのがよい。
【0017】
本発明の水中油型乳化脂で用いる油脂の種類としては、特に限定されないが、例えば、パーム油、パーム核油、ヤシ油、コーン油、オリーブ油、綿実油、大豆油、ナタネ油、米油、ヒマワリ油、サフラワー油、牛脂、乳脂、豚脂、カカオバター、シア脂、マンゴー核油、サル脂、イリッペ脂、魚油、鯨油などの各種植物油脂、動物油脂並びにこれらを水素添加、分別及びエステル交換から選択される一又は二以上の処理を施した加工油脂が挙げられる。本発明ではこれらのうち、大豆油、ナタネ油、パーム油、パーム核油、ヤシ油並びにこれらを水素添加、分別及びエステル交換から選択される一又は二以上の処理を施した加工油脂を用いるのが好ましい。これらの油脂は、単独で用いることもでき、又は二種以上を組み合わせて用いることもできる。
【0018】
本発明の水中油型乳化脂の油脂の含有量は、特に制限はないが、好ましくは3〜80重量%、さらに好ましくは5〜70重量%、最も好ましくは20〜50重量%である。
【0019】
本発明の水中油型乳化脂の水の含有量は、特に制限はないが、好ましくは10〜80重量%、さらに好ましくは20〜70重量%である。
【0020】
また、本発明の水中油型乳化脂は、上記の乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料に加えて、さらに、乳由来の固形分中の灰分の含有量が10重量%以上、好ましくは15重量%以上、さらに好ましくは20重量%以上である乳原料を含むことにより、より豊かなコクのある乳風味を得ることが可能となる。
上記の乳由来の固形分中の灰分とは、乳由来の固形分中に含まれる、乳由来の灰分のことを示す。ナチュラルチーズやプロセスチーズなど、製造の過程で塩類を添加して製造されたものにあっては、添加した塩類が乳由来のものである場合を含め、乳由来の灰分を10重量%以上含有するものが、これに含まれる。
また、上記の乳由来の固形分中の灰分の含有量が10重量%以上である乳原料は、液体状でも、粉末状でも、濃縮物でも構わない。
【0021】
上記の乳由来の固形分中の灰分の含有量が10重量%以上である乳原料としては、例えば、「乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料以外の蛋白質」のうちの、蛋白質濃縮ホエイ、蛋白質濃縮ホエイパウダーがあげられる。また、乳原料であって、蛋白質でない原材料として、乳清ミネラル等があげられる。蛋白質濃縮ホエイとは、ホエイから乳糖を除去したものであり、乳清ミネラルとは、ホエイから乳糖とホエイ蛋白質を除去したもので、乳由来の固形分中の灰分の含有量が、大凡、10〜90重量%であり、多量の灰分を含有している。該灰分には乳風味のコク味を呈する成分が濃縮されているため、この灰分を多く含む乳製品を含有することにより、豊かなコク味のある乳風味を水中油型乳化脂に付与することができる。
【0022】
本発明の水中油型乳化脂における、上記の乳由来の固形分中の灰分の含有量が10重量%以上である乳原料の添加量は、固形分として、好ましくは0.1〜7重量%、さらに好ましくは0.2〜5重量%、最も好ましくは0.3〜2.5重量%である。

【0034】
次に、本発明の水中油型乳化脂の製造方法について説明する。
【0035】
本発明の水中油型乳化脂は、乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料と、乳由来の固形分中の灰分の含有量が10重量%以上である乳原料を水性相及び/又は油性相に添加し、該水性相と該油性相とを乳化することにより得ることができる。
【0036】
具体的には、まず水性相及び油性相を用意する。次に上記の水性相及び/又は油性相に乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料と、乳由来の固形分中の灰分の含有量が10重量%以上である乳原料を添加する。
【0037】
本発明の製造方法では、乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料そのものを、水性相及び/又は油性相に添加してもよいし、乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料に、必要により、乳脂肪、乳糖、生乳、牛乳、特別牛乳、生山羊乳、殺菌山羊乳、生めん羊乳、部分脱脂乳、脱脂乳、加工乳、バター、クリーム、チーズ、クリームチーズ、冷凍変成したクリームチーズ、濃縮ホエイ、アイスクリーム類、濃縮乳、脱脂濃縮乳、無糖れん乳、無糖脱脂れん乳、加糖れん乳、加糖脱脂れん乳、はっ酵乳、乳酸菌飲料、乳飲料、全粉乳、脱脂粉乳、クリームパウダー、ホエイパウダー、蛋白質濃縮ホエイパウダー、バターミルクパウダー、加糖粉乳、調製粉乳、カゼインカルシウム、ホエープロテインコンセントレート及びトータルミルクプロテインの中から選ばれた1種又は2種以上を添加したものを、水性相及び/又は油性相に添加してもよい。但し、後述するように、「乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料以外の蛋白質」を添加する場合は、該蛋白質を水性相及び油性相の乳化後に添加するのが好ましい。
【0038】
次いで、上記水性相と上記油性相とを水中油型に乳化する。
【0039】
さらにこれを、好ましくはバルブ式ホモジナイザー、ホモミキサー、コロイドミルなどの均質化装置により圧力0〜100MPaの範囲で均質化(均質化処理A)してもよい。
【0040】
そして、必要によりインジェクション式、インフージョン式等の直接加熱方式、あるいはプレート式、チューブラー式、掻き取り式などの間接加熱方式を用いたUHT・HTST・低温殺菌、バッチ式、レトルト、マイクロ波加熱等の加熱滅菌もしくは加熱殺菌処理を施してもよく、あるいは直火などの加熱調理により加熱してもよい。
【0041】
さらにこれを、好ましくはバルブ式ホモジナイザー、ホモミキサー、コロイドミルなどの均質化装置により圧力0〜100MPaの範囲で均質化(均質化処理B)してもよい。
そして、必要により急速冷却、徐冷却などの冷却操作を施してもよい。
【0042】
本発明の水中油型乳化脂の製造方法において、「乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料以外の蛋白質」を添加する場合は、該蛋白質を乳化前の水性相及び油性相には添加せずに、水性相及び油性相の乳化後に添加するのが好ましい。また、乳化後に均質化処理Aと均質化処理Bの両方を行う場合は、該蛋白質を均質化処理B後に添加するのが好ましく、均質化処理Aしか行わない場合は、該蛋白質を均質化処理A後に添加するのが好ましく、均質化処理Bしか行わない場合は、該蛋白質を均質化処理B後に添加するのが好ましい。
つまり、「乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料以外の蛋白質」を添加する場合は、該蛋白質を、乳化後、最終の均質化処理後に添加するのが好ましい。
また、「乳由来の固形分中のリン脂質の含有量が2重量%以上である乳原料以外の蛋白質」を、上記の急速冷却、徐冷却などの冷却操作後に添加してもよい。
【0043】
本発明の水中油型乳化脂は、主としてホイップ用クリームとして用いられる他、洋菓子用素材、コーヒーホワイトナー、アイスクリーム、及びパン練り込みなどの用途に用いられるが、本発明の水中油型乳化脂と生クリームとを混合しブレンド物としても本発明の水中油型乳化脂の特性を失うことがない。また、起泡済みクリームとして、冷蔵、冷凍、常温の保管流通条件で用いることもできる。
