Abstract
Description
一方で、昨今の牛海綿状脳症(BSE)の問題や宗教上の理由から、動物由来のゼラチンの代替品が求められており、カプセルにおいても例外ではない。
しかしながら、前述の従来技術においてはこのような皮膜性能を総合的に備えているとは云い難いのが実状であった。とりわけ、従来の皮膜組成では、通常のゼラチン皮膜と同様の皮膜シートの厚さ(約0.9mm)にすると、皮膜シート強度及び接着力が十分ではない場合が多かった。そのため、皮膜シートを薄く(約0.6mm)してカプセル化に必要な皮膜シート強度及び接着力を確保していた。しかし、皮膜シートを薄くすると内容液の粒子が皮膜の接合部分に噛み込んだ場合には、接合部分にごく小さな穴が開き、カプセル内容物が漏れる不具合が生じる場合もあった。この不具合は、皮膜シートを薄くする程顕著であった。
また、本発明は、上記軟カプセル皮膜を用いて得られる軟カプセルを提供するものである。
カラギナンは、硫酸基をもつガラクタンの一種であり、紅藻類に存在していることが知られている。カラギナンは、日本の食品添加物の規定では、「精製カラギナン」、「加工ユーケマ藻類」、「ユーケマ藻末」の三種類が規定されている(日本食品添加物協会刊、「既存添加物名簿収載品目リスト注解書」(1999)参照)が、これらは精製度が異なるのみで、本質的には全て本発明におけるカラギナンに含まれる。
カラギナンは、それぞれ純粋品でもよいし、標準化物質を含んだものでもよい。ここで、標準化物質としては、ショ糖、ブドウ糖、マルトース、乳糖等の糖類及びデキストリンからなる群から選ばれた1種又は2種以上が挙げられる。カラギナンに標準化物質が含まれる場合、標準化物質の割合は50質量%以下、更に45質量%以下が好ましい。なお、カラギナンとして標準化物質を含んだものを利用する際、後述するカラギナンの含有量は、標準化物質を含むものとする。
(A)イオタカラギナンの含有量は、皮膜シート強度の点、弾力性の点から、固形成分の合計量中、20質量%以上が好ましく、25質量%以上がより好ましく、30質量%以上がより好ましく、35質量%以上が更に好ましい。また、皮膜液粘度の点から、固形成分の合計量中、55質量%以下が好ましく、50質量%以下がより好ましく、45質量%以下が更に好ましい。また、(A)イオタカラギナンの含有量は、固形成分の合計量中、20~55質量%が好ましく、25~55質量%がより好ましく、30~50質量%がより好ましく、35~45質量%が更に好ましい。なお、この発明において固形成分とは、皮膜組成の中から、精製水と可塑剤を除いたもののことである。
澱粉糊液は、常法、例えば、澱粉を水中等で加熱して澱粉質を糊化させて調製される。澱粉糊液における澱粉の含有量は、特に制限されないが、1質量%以上が好ましく、5質量%以上がより好ましく、10質量%以上がより好ましい。
なお、澱粉糊液の調製に用いられる澱粉は、未化工、すなわち、酸処理、アルファ化、エーテル化、アセチル化等の化工を行っていないものが好ましい。
超音波処理により、澱粉糊液の粘度は低下し、澱粉分散物が得られる。超音波処理後の澱粉分散物の粘度(B型粘度計、澱粉の含有量20質量%、液温80℃)は、澱粉の種類によって相違するものの、350mPa・s以下が好ましく、10~350mPa・sがより好ましい。
本発明において、(B)澱粉糊液に超音波処理がされてなる澱粉分散物は市販品を使用することもできる。
カッパカラギナンの含有量は、ゲル化強度の点から、固形成分の合計量中、0.1質量%以上が好ましく、0.3質量%以上がより好ましく、0.5質量%以上が更に好ましい。また、皮膜強度(脆弱性)の観点から3.5質量%以下が好ましく、2.5質量%以下がより好ましい。カッパカラギナンの含有量は、固形成分の合計量中、0.1~3.5質量%が好ましく、0.3~3.5質量%がより好ましく、0.5~2.5質量%が更に好ましい。
ただし、皮膜の物性、軟カプセルの品質を考慮して、イオタ又はカッパカラギナン以外のゲル化剤の含有量は、固形成分の合計量中、1質量%以下、更に0.5質量%以下、特に0.1質量%以下であることが好ましい。
澱粉糊液に超音波処理がされてなる澱粉分散物以外の澱粉類の含有量は、皮膜シート強度、接着力及び乾燥後の弾力性の点から、固形成分の合計量中、50質量%以下が好ましく、47質量%以下がより好ましく、45質量%以下が更に好ましく、10質量%以下が更に好ましい。下限値は0質量%である。
本発明の軟カプセル皮膜における可塑剤の含有量は、柔軟性の点から、固形成分の合計量100質量部に対して、30質量部以上が好ましく、35質量部以上がより好ましい。また、付着性の点から、固形成分の合計量100質量部に対して、60質量部以下が好ましく、50質量部以下がより好ましい。可塑剤の含有量は、固形成分の合計量100質量部に対して、30~60質量部が好ましく、35~50質量部がより好ましい。
以下に、カプセルに含有し得るものを例示する。これら各成分は、カプセル剤中のいかなる部分にも含有しうる。
