【発明の属する技術分野】
本発明は、β−グルカン、特にβ−1,3−1,6−グルカンを含むアウレオバシジウム属に属する菌の培養物と乳酸菌の菌体とを有効成分として含有する便秘改善剤及びそれを含有する飲食品に関する。
【0002】
【従来の技術】
アウレオバシジウム属(Aureobasidium sp.)に属する菌(通称、黒酵母)が産生するβ−1,3−1,6−グルカンは、免疫増強作用、抗腫瘍活性、ガン細胞増殖抑制作用、抗アレルギー作用、抗炎症作用、コレステロール低下作用、抗血栓作用、食物繊維作用、血圧降下作用、血糖降下作用、肝機能亢進等の様々な生理活性を有していることが知られており、機能性素材として利用されている。
【0003】
例えば、上記β−1,3−1,6−グルカンを食品や医薬品用途、特に便秘の予防・改善のために用いた例として、下記特許文献1には、不完全菌黒色菌科アウレオバシジウム(Aureobacidium)属の菌(微工研寄託No.4257号)が産生する多糖を主成分とする整腸剤その他の医薬が開示されている。
【0004】
また、下記特許文献2には、フラクトオリゴ糖とβ−1,3−1,6グルカンを主成分とする飲食品の製造方法が開示されており、この飲食品は、健康維持飲料(腸内ビフィズス菌の増殖、便秘防止、免疫増強)、整腸剤等に利用できる旨記載されている。
【0005】
また、下記特許文献3には、β−1,3−1,6−グルカン及びリンゴ抽出物を含有する組成物が開示されており、この組成物が飲料や皮膚塗布剤として有用である旨、該飲料には、各種アレルギー症状の低減効果、免疫異常疾患の改善効果、がん抑制効果、血管障害疾患の改善効果、ウイルス性疾患の改善効果、泌尿器系疾患の改善効果、便秘、下痢等の消化器系疾患の改善効果が期待できる旨記載されている。

【発明が解決しようとする課題】
しかしながら、アウレオバシジウム属(Aureobasidium sp.)に属する菌の培養液に含まれるβ−1,3−1,6−グルカンの濃度は低濃度(通常、0.2%(w/v)前後、高くても0.5〜0.6%(w/v))であるため、上記特許文献2に記載されているように培養液をそのまま利用する場合は、比較的大量に摂取しなければ十分な生理活性が期待できないという問題があった。
【0008】
また、β−1,3−1,6−グルカン濃度を高めるために、上記特許文献1に記載されているように精製を行った場合は、精製コストがかかるだけでなく、精製工程で培養液中に含まれる他の有用成分(例えば、β−グルカンの吸収を助ける成分であるリン、カリウム、マグネシウム、ビタミンC、オレイン酸、リノール酸等)が失われてしまうという問題があった。
【0009】
一方、上記特許文献3には、アウレオバシジウム(Aureobacidium)属の微生物の培養液に、ビフィズス活性を補完する目的で、イソマルトオリゴ糖、ガラクトオリゴ糖、キシルシュクロース、キシロオリゴ糖、キトサン、グリコマクロペプチド、小麦ファイバー、コーンファイバー、大豆オリゴ糖、ヘミセルロース又は大豆ペプチド等を配合できることが記載されているが、上述したように培養液中のβ−1,3−1,6−グルカン含量が低いので、上記のような成分を併用しても、十分な便秘改善効果はあまり期待できない。
【0010】
したがって、本発明の目的は、アウレオバシジウム属(Aureobacidium sp.)に属する菌の培養液に含まれる様々な有用成分を損なうことなく利用でき、優れた便秘改善効果を有し、更には免疫賦活効果等も期待できる便秘改善剤及びそれを含有する飲食品を提供することにある。
【0011】
【課題を解決するための手段】
上記目的を達成するため、本発明の便秘改善剤は、アウレオバシジウム プルランス M-1 Aureobasidium pullulans M-1 )( FERM P-19213 を培養して得られるβ−1,3−1,6−グルカンを含む培養物と、乳酸菌エンテロコッカス・フェカリス(Enterococcus faecalis)菌体とを有効成分として含有することを特徴とする。
【0012】
本発明の便秘改善剤は、アウレオバシジウム プルランス M-1 Aureobasidium pullulans M-1 )( FERM P-19213 を培養して得られるβ−1,3−1,6−グルカンを含む培養物をそのまま用いるので、該培養物に含まれるβ−1,3−1,6−グルカン以外の様々な有用成分も損なうことなく利用することができる。そして、該培養物に乳酸菌エンテロコッカス・フェカリス(Enterococcusfaecalis)菌体を配合しているので、これらの成分の相乗効果により、優れた便秘改善効果だけでなく、免疫賦活効果等も期待できる。
【0013】
本発明の便秘改善剤においては、アウレオバシジウム プルランス M-1(Aureobasidium pullulansM-1)(FERM P-19213)を用いるので、より生理活性の高いβ−1,3−1,6−グルカンを得ることができる。
【0014】
また、固形分中に、前記培養物をβ−1,3−1,6−グルカン換算で1〜40質量%含有し、かつ前記乳酸菌菌体を4〜95質量%含有することが好ましい。
【0015】
更に、前記培養物は、固形分中にβ−1,3−1,6−グルカンを1質量%以上含むものであることが好ましい。
【0018】
更にまた、前記乳酸菌は加熱殺菌されたものであることが好ましい。この態様によれば、加熱処理が必要な飲食品にも幅広く添加することができ、また、保存安定性が高く、飲食品や医薬品の原料として用いる場合の安全性も非常に高い便秘改善剤を提供できる。
【0020】
【発明の実施の形態】
本発明においては、アウレオバシジウム属( Aureobasidium sp. )に属する菌であるアウレオバシジウム プルランス M-1 Aureobasidium pullulans M-1 、独立行政法人産業技術総合研究所特許生物寄託センター寄託番号 FERM P-19213 )を用いる。これを培養して得られる培養物(以下、単に培養物という。)としては、β−1,3−1,6−グルカン生産能を有する菌を培養した培養液そのもの、該培養液の濃縮液、あるいは該培養液から水分を除いた固形物などを用いることができる。
【0021】
お、本発明において、β−1,3−1,6−グルカンとは、グルコースがβ−1,3結合した主鎖からβ−1,6結合でグルコースが分岐した構造を有するものを意味する。
【0022】
上記アウレオバシジウム属(Aureobasidium sp.)に属する菌であるアウレオバシジウム プルランス M-1 Aureobasidium pullulans M-1 )( FERM P-19213 の培養は、公知の方法(特開昭57−149301号公報等参照)に準じて行うことができる。すなわち、炭素源(ショ糖)0.5〜1.0質量%、N源0.1質量%、その他微量物質(例えば、ビタミン類、無機質)を加えた培地(pH5.2〜6.0)に菌を接種し、温度20〜30℃で2〜3日間通気培養、好ましくは通気撹拌培養すればよい。β−1,3−1,6−グルカンが生成されるにしたがって培養液の粘度が上昇し、粘性の高いジェル状になる。このようにして得られる培養液には、通常、0.6〜1.8質量%の固形分が含まれており、該固形分中にはβ−1,3−1,6−グルカンが5〜80質量%含まれている。また、β−1,3−1,6−グルカン以外にも、例えば、該グルカンの吸収を助ける成分であるリン、カリウム、マグネシウム、ビタミンC、オレイン酸、リノール酸等の他の有用成分も含まれているので、β−1,3−1,6−グルカンの有する生理活性効果を効率よく発揮できる。本発明においては、固形分中にβ−1,3−1,6−グルカンを1質量%以上含む培養物が好ましく用いられ、固形分中にβ−1,3−1,6−グルカンを5質量%以上含む培養物がより好ましく用いられる。培養物中のβ−1,3−1,6−グルカン濃度が低すぎると、該グルカンの生理活性効果が十分に期待できない。
【0023】
なお、β−1,3−1,6−グルカンの定量は、特公平3−48201号公報に記載された方法に準じて行うことができる。すなわち、培養終了後、培養液を殺菌して、遠心分離して菌体を除去し、得られた溶液にクロロホルム/ブタノール混合液を10%(v/v)加えて振とう(Sevage法)した後、遠心処理してクロロホルムと不溶物を除去する。この操作を2回繰り返した後、エタノール沈殿により、沈殿物を回収して蒸留水に溶解し、酵素処理により、プルランを分解し、蒸留水中で透析を行い、透析液をエタノール沈殿して、沈殿物(β−1,3−1,6−グルカン)を回収して収量を求めればよい。
【0024】
本発明においては、上記のようにして得られる培養液をそのまま加熱又は加圧加熱殺菌して用いてもよく、遠心分離等により菌体を分離除去した後殺菌して用いてもよい。また、必要に応じて濃縮したもの、更には乾燥したものを用いることもできる。なお、アウレオバシジウム属(Aureobasidium sp.)に属する菌の培養物は、増粘安定剤等の食品添加物として使用されているものであり、安全性は高い。
【0025】
本発明において、乳酸菌は、乳酸菌エンテロコッカス・フェカリス( Enterococcus faecalis )を用いる。乳酸菌エンテロコッカス・フェカリス( Enterococcus faecalis )は単独で用いてもよく、エンテロコッカス・フェカリス(Enterococcusfaecalis)、エンテロコッカス・フェシウム(Enterococcus faecium)、ラクトバチルス・アシドフィルス(Lactobacillus acidophilus)、ラクトバチルス・カゼイ(Lactobacillus casei)、ストレプトコッカス・クレモリス(Streptococcus cremoris)、ストレプトコッカス・ラクティス(Streptococcus lactis)、ストレプトコッカス・サーモフィラス(Streptococcus thermophilus)、ビフィドバクテリウム・ロンガム(Bifidobacterium Longum)、ビフィドバクテリウム・ブレーベ(Bifidobacterium breve)、ビフィドバクテリウム・ビフィダム(Bifidobacterium bifidum)等の乳酸菌の少なくとも1種を併用してもよい。
【0026】
なお、エンテロコッカス・フェカリス(Enterococcus faecalis)、エンテロコッカス・フェシウム(Enterococcus faecium)は乳酸菌製剤等に用いられている乳酸菌である。ラクトバチルス・カゼイ(Lactobacillus casei)、ラクトバチルス・アシドフィルス(Lactobacillus acidophilus)は、チーズ、発酵乳、ヨーグルト、乳酸菌飲料等に用いられている乳酸菌である。ストレプトコッカス・クレモリス(Streptococcus cremoris)、ストレプトコッカス・ラクティス(Streptococcus lactis)、ストレプトコッカス・サーモフィラス(Streptococcus thermophilus)は、チーズ、ヨーグルト等に用いられている乳酸菌である。ビフィドバクテリウム・ロンガム(Bifidobacterium Longum)、ビフィドバクテリウム・ブレーベ(Bifidobacterium breve)、ビフィドバクテリウム・ビフィダム(Bifidobacterium bifidum)は発酵乳等に用いられている乳酸菌である。したがって、これらの乳酸菌は、いずれも当業者が容易に入手できるものである。
【0027】
本発明においては、エンテロコッカス・フェカリス(Enterococcus faecalis、例えば、ATCC 19433、ATCC 14508、ATCC 123655、IFO 16803等)を用いることができる。エンテロコッカス・フェカリス(Enterococcus faecalis)は、強い免疫賦活活性を有していることが知られており、上記培養物と併用することにより、これらの成分による相乗的な便秘改善効果及び免疫賦活効果が期待できる。
【0028】
本発明において、上記乳酸菌は加熱殺菌されたものであることが好ましい。これにより、加熱処理が必要な飲食品にも幅広く添加することができ、また、保存安定性が高く、飲食品や医薬品の原料として用いる場合の安全性も非常に高くなる。
【0029】
