Description

【0001】
【発明の属する技術分野】
本発明は、飲食品の風味改善剤、風味改善方法などに関し、詳細には、α−結合ガラクトオリゴ糖を含有する飲食品の風味改善剤及びこれが添加された飲食品並びに飲食品の風味改善方法に関する。
【0002】
【従来の技術】
今日、食生活の多様化や健康志向の高まりと相俟って様々な飲食品が提供されている。
飲食品は、果汁飲料や野菜ジュースなどの飲食品の素材をそのまま用いたものや、ハム、ウインナー、ジャム、ビール、ワイン、缶詰など飲食品の素材を加工したものや、あるいは野菜の煮物、卵焼き、野菜炒め、ピラフなど飲食品の素材を調理したものなど様々なものがある。そして、これら飲食品の中には、味にいわゆる「くせ」があり、人々の嗜好が多様化しているというものの、多くの人に好ましくないと思われる「くせのある味」を有するものがある。このような「くせのある味」として、例えば、飲食品の酸味、苦味、渋味、えぐ味などがあり、これらが人々の飲食品に対する摂取意欲を減退させることがある。一方、飽食の時代でもある今日、人々の美食に対する欲求はますます高まりつつあり、飲食品にいわゆる「旨みのある味」が求められるようになってきている。このような飲食品の「旨みのある味」は、例えば、飲食品の素材自体の風味、なめらかさ、コク味などを増強させることにより得ることができる。
【0003】
かかる事情の下、従来より様々な風味改善方法や風味改善剤が提供されている。特許第3208113号公報には、ヘスペリジン配糖体またはヘスペリジン配糖体とヘスペリジンとの混合物を、野菜飲料の青臭み、酸味、苦味の低減、生薬含有飲食品に苦味、渋味、薬臭の低減などを行う風味改善方法及び風味改善剤が提供されている。また、特開平9−117262号公報には、青臭み、酸味等の強い野菜・果物類を原料とする飲食品の製造において、エリスリトールを添加する野菜・果物類の青臭み、酸味等の抑制方法が提供されている。
【0004】
【発明が解決しようとする課題】
しかしながら、従来のいずれの風味改善方法や風味改善剤においても、ビフィズス菌の選択増殖活性などに優れ、飲食品素材や医薬品素材などとして注目されるα−結合ガラクトオリゴ糖が飲食品の風味を改善することについて想到し得たものは存しない。
そこで、本発明は、新たな風味改善剤、風味が改善された飲食品及び風味改善方法を提供することを課題とする。
【0005】
【課題を解決するための手段】
上記課題を解決するため、本発明者らはα−結合ガラクトオリゴ糖を様々な飲食品に添加して研究を重ねた結果、本発明に想到した。
すなわち、本発明は、飲食品の風味の改善が、(1)果汁飲料の酸味、苦味、渋味、えぐ味を各々低減すること、(2)卵焼きの卵の風味を増強すること、(3)野菜の煮物の野菜の風味を増強すること、(4)野菜入りケーキの野菜の風味を増強すること、(5)リンゴ入りケーキの酸味を低減し、風味を増強すること、(6)コーヒーの苦みを低減すること、(7)ジャムの素材の風味を増強すること又は(8)ビールのなめらかさ、コク味を各々増強し苦みを低減すること、であるアスペルギルス・ニガー(Aspergillus niger)APC-9319株(FERM BP-7680)の生産するα−ガラクトシダーゼによりガラクトースを基質として合成されるα−(Gal)n(Gal:ガラクトース、nは2〜10の整数)で示されるオリゴ糖が混在したα−結合ガラクトオリゴ糖を含有する飲食品の風味改善剤を要旨とする。
【0006】
また、本発明は、上記のα−結合ガラクトオリゴ糖を含有する飲食品の風味改善剤を添加されてなる飲食品を要旨とする。
【0007】
また、本発明は、飲食品の風味の改善が、(1)果汁飲料の酸味、苦味、渋味、えぐ味を各々低減すること、(2)卵焼きの卵の風味を増強すること、(3)野菜の煮物の野菜の風味を増強すること、(4)野菜入りケーキの野菜の風味を増強すること、(5)リンゴ入りケーキの酸味を低減し、風味を増強すること、(6)コーヒーの苦みを低減すること、(7)ジャムの素材の風味を増強すること又は(8)ビールのなめらかさ、コク味を各々増強し苦みを低減すること、であるアスペルギルス・ニガー(Aspergillus niger)APC-9319株(FERM BP-7680)の生産するα−ガラクトシダーゼによりガラクトースを基質として合成されるα−(Gal)n(Gal:ガラクトース、nは2〜10の整数)で示されるオリゴ糖が混在したα−結合ガラクトオリゴ糖を含有する飲食品の風味改善剤を添加する、飲食品の風味改善方法を要旨とする。
【0008】
【発明の実施の形態】
本発明の飲食品の風味改善剤は、α−結合ガラクトオリゴ糖を含有するものである。α−結合ガラクトオリゴ糖は、α−ガラクトシル基を有するオリゴ糖で、メリビオース、マンニノトリオース、ラフィノース、スタキオースも含まれ、これらはビートや大豆オリゴ糖から製造することができる。また、これらのα−結合ガラクトオリゴ糖は、市販されているのでこれらを用いることもできる。
【0009】
また、α−結合ガラクトオリゴ糖は、酵素により合成したものを用いることもできる。
酵素による合成は、α−ガラクトシダーゼの脱水縮合反応を利用してガラクトースあるいはガラクトースを含む物質の加水分解物を基質として行うことができる。ガラクトースを基質として合成することにより、一般的にα−(Gal)n(Gal:ガラクトース、nは2〜10の整数)で示されるα−ガラクトビオース、α−ガラクトトリオース、α−ガラクトテトラオース以上のオリゴ糖が混在したα−結合ガラクトオリゴ糖が得られる。
また、ガラクトースとグルコースを基質として合成することにより、一般的にα−(Gal)nGlc(Glc:グルコース、nは1〜9)で示されるα−ガラクトシルグルコースとα−ガラクトビオースなどガラクトースのみからなるオリゴ糖が混在したα−結合ガラクトオリゴ糖が得られる。なお、ガラクトースを含む物質の加水分解物とは、例えば、乳糖にβ−ガラクトシダーゼを作用させて得られるガラクトースとグルコースの混合物は勿論のこと、ガラクトースに別途グルコースを混合して基質とする場合をも包含する。
α−ガラクトシダーゼは、ガラクトースあるいはガラクトースを含む物質の加水分解物を基質としてα−結合ガラクトオリゴ糖を合成できるものであれば起源などは特に限定されないが、収率などの観点からアスペルギルス・ニガー(Aspergillus niger)が生産するものが好ましく、アスペルギルス・ニガー(Aspergillus niger)APC−9319株(FERM BP−7680)の生産するものがより好ましい。
【0010】
また、本発明の飲食品の風味改善剤は、α−結合ガラクトオリゴ糖の風味改善効果を減弱させないようなα−結合ガラクトオリゴ糖以外の成分、例えば他の風味改善剤などを含んでも良いが、α−結合ガラクトオリゴ糖を単独で用いることもできる。また、α−結合ガラクトオリゴ糖は、甘味を有するが、スクロースほどの強い甘味ではないので、甘過ぎることが好まれない飲食品に添加して用いることもできる。
【0011】
本発明の飲食品の風味改善剤による風味の改善は、飲食品の好ましくないいわゆる「くせのある味」の低減に広く用いることができる。飲食品の「くせのある味」とは、飲食品の酸味、苦味、渋味、えぐ味は勿論のこと、いがらっぽさ、生臭さ、乳臭さ、青臭さ、特異臭など様々なものを挙げることができる。これらの味を呈する飲食品であれば特に限定されず本発明の風味改善剤を用いることができ、酸味のある飲食品としてリンゴジュース、オレンジジュースなどの果汁飲料を挙げることができ、苦味や渋味のある飲食品としてコーヒー、お茶、紅茶などの飲食品を挙げることができる。また、えぐ味のある飲食品として、グレープフルーツジュースやハチミツなどを挙げることができ、生臭さのある飲食品として魚介類加工食品などを挙げることができる。その他、野菜ジュースの青臭さ、牛乳、乳製品の乳臭さなどを挙げることができる。
【0012】
また、本発明の飲食品の風味改善剤による飲食品のいわゆる「旨みのある味」の増強は、本来有する飲食品の素材の「味」を調理や加工をしても保持させることにより行うことができ、野菜の煮物における「野菜の味」や卵焼きにおける「卵の味」を増強させることなどを挙げることができる。また、コク味や味のなめらかさを増強させることにより行うこともでき、例えば、ビールなどでよく言われるなめらかでこくがある味を代表例として挙げることができる。
【0013】
飲食品の風味を改善するための飲食品の風味改善剤の添加量は、飲食品に対してα−結合ガラクトオリゴ糖を0.1〜80重量%の割合で添加することが好ましく、より好ましくは1〜70重量%である。0.1重量%より少ないと十分な風味改善効果を期待できないからであり、80重量%より多くしてもコスト面で無駄となるからである。
【0014】

In addition, the hydrolyzate of a substance containing galactose includes, for example, a mixture of galactose and glucose obtained by allowing β-galactosidase to act on lactose, as well as a case where galactose is separately mixed with glucose as a substrate. Include.
The origin of α-galactosidase is not particularly limited as long as it can synthesize α-linked galactooligosaccharides using galactose or a hydrolyzate of a substance containing galactose as a substrate, but Aspergillus niger from the viewpoint of yield and the like. ) Are preferable, and those produced by Aspergillus niger APC-9319 strain (FERM BP-7680) are more preferable.
[0010]
In addition, the flavor improving agent for foods and beverages of the present invention may contain components other than α-linked galactooligosaccharide such as other flavor improving agents that do not diminish the flavor improving effect of α-linked galactooligosaccharide, -A conjugated galactooligosaccharide can also be used alone. In addition, α-linked galactooligosaccharide has sweetness but is not as strong as sucrose, so it can be added to foods and beverages that are not preferred to be too sweet.
[0011]
The improvement of the flavor by the flavor improving agent of the food / beverage products of this invention can be widely used for reduction of the unpreferable so-called “skinned taste” of the food / beverage products. The “spicy taste” of foods and drinks includes not only the acidity, bitterness, astringency, and savory taste of foods and drinks, but also various flavors such as garlic, raw odor, milky odor, blue odor and peculiar odor. Can be mentioned. If it is food / beverage products which exhibit these tastes, it will not specifically limit, The flavor improving agent of this invention can be used, Fruit juice drinks, such as apple juice and orange juice, can be mentioned as food / beverage products with acidity, bitterness and astringency Foods and beverages such as coffee, tea, and tea can be listed as tasteful foods and beverages. Moreover, grapefruit juice, honey, etc. can be mentioned as food / beverage products with a pungent taste, and seafood processed foods etc. can be mentioned as food / beverage products with a raw smell. Other examples include the blue odor of vegetable juice, the milky odor of milk and dairy products.
[0012]
In addition, enhancement of the so-called “taste with taste” of the food and drink by the flavor improver of the food and drink of the present invention is carried out by retaining the “taste” of the material of the food and drink originally possessed even after cooking or processing. And “enhancing the taste of vegetables” in boiled vegetables and “egg taste” in fried eggs. Moreover, it can also carry out by enhancing the richness and smoothness of a taste, for example, the smooth and rich taste often said by beer etc. can be mentioned as a representative example.
[0013]
The addition amount of the flavor improving agent for food and drink for improving the flavor of the food and drink is preferably 0.1 to 80% by weight of α-linked galactooligosaccharide, and more preferably. 1 to 70% by weight. This is because if the amount is less than 0.1% by weight, a sufficient flavor improving effect cannot be expected, and if it exceeds 80% by weight, the cost is wasted.
