Description
前記混合工程は、pHが6以上の条件下で行う。
サンショオール類と、抗酸化剤と、液体とを含み、
前記液体は、水及び水溶性の有機溶媒のうちの少なくとも一方を含む、サンショオール類含有組成物。
サンショオール類と抗酸化剤とを液体中で混合する混合工程を含み、
水及び水溶性の有機溶媒のうちの少なくとも一方を含み、
前記混合工程は、pHが6以上の条件下で行う、サンショオール類含有組成物の製造方法。
本実施形態のサンショオール類の安定化方法は、サンショオール類と抗酸化剤とを液体中で混合する混合工程を含む。この安定化方法によれば、サンショオール類を長期にわたって安定に保存しやすくなり、サンショオール類を、食品、補助食品、飲料、医薬品、医薬部外品、化粧品、飼料、洗剤、日用品等の各種製品に用いたときに、これらの製品中においてサンショオール類を安定した状態で存在させることができるため、これら製品の長寿命化を図ることが期待できる。
サンショオール類は、山椒から抽出されるものであってもよく、合成されたものであってもよい。本実施形態のサンショオール類としては、α−サンショオール、β−サンショオール、γ−サンショオール、δ−サンショオール、ヒドロキシ−α−サンショオール、ヒドロキシ−β−サンショオール、ヒドロキシ−γ−サンショオール等を挙げることができる。このうち、サンショオールは、山椒に多く含まれる成分であるヒドロキシ−α−サンショオール、α−サンショオールであることが好ましい。
抗酸化剤は、一般に抗酸化作用を有するとされる物質であり、特に、食品や医薬品に使用することができる安全な抗酸化剤が好ましい。本実施形態における抗酸化剤は、水溶性のものであってもよく、脂溶性のものであってもよい。
サンショオール類の安定化方法における混合工程は、サンショオール類と抗酸化剤とを液体中で混合する工程である。サンショオール類及び抗酸化剤はそれぞれ、液体に溶解していてもよく、液体に分散していてもよい。この混合工程で用いる液体は、特に限定されず、有機溶媒、水、又は、水と有機溶媒との混合液体を挙げることができる。山椒抽出物に含まれるサンショオール類を安定化する場合、混合工程で用いる液体は、サンショオール類の山椒抽出物の抽出に用いた抽出溶媒であってもよい。また、合成によって得られたサンショオール類を安定化する場合は、混合工程で用いる液体は、合成時に用いる溶媒、例えば精製に用いる溶媒等であってもよい。
本実施形態のサンショオール類含有組成物は、サンショオール類と、抗酸化剤と、液体とを含み、pHは6以上であり、液体は水及び水溶性の有機溶媒のうちの少なくとも一方を含むものである。サンショオール類、抗酸化剤、及び液体については上記したとおりである。サンショオール類含有組成物は、水及び水溶性の有機溶媒のうちの少なくとも一方を含んでいればよく、水と水溶性の有機有機溶媒との混合液体であってもよい。また、抗酸化剤は、水溶性の抗酸化剤であってもよく、脂溶性の抗酸化剤であってもよく、2種以上の抗酸化剤を含んでいてもよい。サンショオール類含有組成物は、サンショオール類及び抗酸化剤が液体中に存在するものであればよく、サンショオール類及び抗酸化剤が分散した分散状態であってもよく、乳化剤等を添加して乳化状態としたものであってもよい。
本実施形態のサンショオール類含有組成物の製造方法は、サンショオール類と抗酸化剤とを液体中で混合する混合工程を含み、液体は水及び水溶性の有機溶媒のうちの少なくとも一方を含み、混合工程は、pHが6以上の条件下で行う方法である。サンショオール類、抗酸化剤、液体、及び混合工程については、上記したとおりである。混合工程で用いる液体は、水及び水溶性の有機溶媒のうちの少なくとも一方を含んでいればよく、水と水溶性の有機溶媒との混合液体であってもよい。また、抗酸化剤は、水溶性の抗酸化剤であってもよく、脂溶性の抗酸化剤であってもよく、2種以上の抗酸化剤を含んでいてもよい。
高速液体クロマトグラフィ(HPLC)分析は、逆相系で行った。HPLC装置はLC−2010(島津製作所製)であり、ポンプはLC−10ADvp、カラムオーブンはCTO−10ACvp、システムコントローラーはSCL−10Avpで構成されている。カラムはInertSustainSwift C18 4.6×250mm(GL Sciences)、カラム温度は40℃、移動相は、A液が30%アセトニトリル、B液が80%アセトニトリル、グラジエント条件は、0min B液0%→35min B45%→50min B液100%→51min B液0%→55min B液0%とし、検出波長は270nmで行い、ヒドロキシ−α−サンショオールのピーク面積値から、ヒドロキシ−α−サンショオールの含有量を算出した。
pH測定装置(pHメータF52、HORIBA社製)を用いて行った。
完熟サンショウ(和歌山県産、品種名ブドウザンショウ)を乾燥させ、篩で篩って果皮と種子とを分離し、果皮と種子との間にあるじょうのう膜を集めた。このじょうのう膜をラボミルサー(LM−PLUS、大阪ケミカル株式会社製)で粉砕して、目開き250μmの篩を通過させて、篩を通過したサンショウのじょうのう膜の粉末状物を得た。この粉末状物0.4gに対して、抽出溶媒として50体積%のエタノール水溶液8mLを加えて懸濁し、ボルテックスミキサーで振とうし、超音波処理を行って遠心分離した後、上清を採取した。採取した上清と表1に示す抗酸化剤とをスピッツ管に入れ、温度70℃に設定したオイルバス中に保温した。上清1mL中のヒドロキシ−α−サンショオールの含有量は2.5μmolであった。また、抗酸化剤の添加量及びヒドロキシ−α−サンショオール1molに対するモル比は、表1及び表2に示すとおりである。
抗酸化剤を添加しないこと以外は実施例1〜31と同様にして、オイルバス保温前の試料、及び、オイルバス保温9日目のヒドロキシ−α−サンショオールの含有量をHPLCを測定した。その結果を表2に示す。比較例1では、pH調整は行っていない。
抗酸化剤として、(a)没食子酸ナトリウム0.65μmol/mLを用いた場合、(b)アスコルコルビン酸ナトリウム25μmol/mLを用いた場合、(c)没食子酸ナトリウム0.65μmol/mLとアスコルコルビン酸ナトリウム25μmol/mLとを用いた場合について、実施例1〜31と同様の手順で、オイルバスでの保温8日目の試料中のヒドロキシ−α−サンショオールの含有量をHPLCで測定し、残存率を測定した。
抗酸化剤として、(b)アスコルコルビン酸ナトリウム25μmol/mLを用いた場合、(d)トコフェロール0.58μmol/mLを用いた場合、(e)没食子酸ナトリウム0.65μmol/mLとアスコルコルビン酸ナトリウム25μmol/mLとを用いた場合について、実施例32と同様にして、オイルバスでの保温8日目の試料中のヒドロキシ−α−サンショオールの含有量をHPLCで測定し、残存率を測定した。
実施例1〜31と同様にして、オイルバスで保温する前の上清及び抗酸化剤を含む試料を準備した。上清と混合した抗酸化剤の種類及び量は、表3に示すとおりである。この試料に、1gのデンプンを添加して凍結乾燥し、この凍結乾燥物を温度70℃に設定したオイルバス中で65時間保温した後、凍結乾燥物をエタノールに溶解させて、ヒドロキシ−α−サンショオールの含有量をHPLCで測定し、残存率を算出した。その結果を表3に示す。
抗酸化剤を添加しないこと以外は実施例34〜37と同様にして、凍結乾燥物中のヒドロキシ−α−サンショオールの含有量をHPLCで測定し、残存率を算出した。その結果を表3に示す。
実施例1〜31と同様にして、上清を準備し、この上清に1gのデンプンを添加して凍結乾燥した後、粉末状の抗酸化剤を添加して、粉末混合物を得た。得られた粉末混合物を温度70℃に設定したオイルバス中で65時間保温した後、この粉末混合物をエタノールに溶解させて、ヒドロキシ−α−サンショオールの含有量をHPLCで測定し、残存率を算出した。その結果を表3に示す。
