Description
1. 乾燥輸送形態を開発するのにおける困難性
産業における栄養処方の多くは、錠剤、カプセルまたは乾燥混合物の形態である。そのようなサプリメントの処方者および製造メーカーにとって、これら製品の油状、ろう状または粘液状の性質が原因で、カロテノイド、トコフェロールおよびトコトリエノール等のビタミンE源、PC-豊富なレシチンの濃縮形態、植物ステロールおよび植物スタノール、PUFA豊富な様々な油ならびにω-3脂肪酸のような疎水性栄養素を単独または他の栄養素との組み合わせて、乾燥形態に組み込むことは重要な問題である。噴霧乾燥粉末、顆粒剤またはゼラチンビーズ等のいくつかの選択肢は、選ばれた製品でのみ機能し、打錠システム下で必ずしも十分に機能するわけではない。疎水性栄養素の使用における要求のいくつかを以下で説明する。
b. カロテノイド安定化のための他の選択肢は、天然に存在するか、または添加された酸化防止剤に加えて、油媒体の保護膜を提供するために、前記油媒体中のカロテノイドを輸送することによるものである。乾燥輸送形態は、安定化させることがさらに困難であると考えられる。
c. トコフェロールおよびトコトリエノールは、通常、植物油の存在下の油性媒体中で見られる。そのような油性製品は、それらを粉末、顆粒剤またはビーズに変換するための専門的な技術を用いずに、錠剤のような乾燥輸送形態において最小の用量の場合を除き、使用することは困難である。
d. 有効成分PCが豊富(20-95%)なレシチンは、直接圧縮または流動性粉末に適切でない、粘性ペーストまたはろう状塊となる傾向がある。
e. 植物ステロールおよび植物スタノールは、通常、脂質に基づくサプリメントを通じて補給される油性製品である。これらを流動性または直接圧縮乾燥輸送形態に組み込むことにより、栄養剤の処方者および製造メーカーにとっての選択肢がかなり増加する。
f. PUFAs、GLAおよびω-3脂肪酸は、それらの油性の性質が原因で、一般に、錠剤およびカプセルベースのサプリメントにおける使用は、控えめおよび稀である。従来の乾燥輸送変換技術は、流動性および直接圧縮ビーズのための良い解決手段を提供できない。
本来、カロテノイドは、室温で不安定である。それらの安定性は、光、熱、空気(酸素)および酸性環境の影響を受ける。天然のトコフェロール、アスコルビン酸誘導体およびクエン酸塩のような特定の安定化酸化防止剤の添加によって、それらの安定性を増加できることが知られている。
a. 錠剤への処方に適切な、有効成分(カロテノイドおよび脂質)のビーズのような固体形態、
b. 錠剤への圧縮の際、有効成分が溶出しないビーズ、
c. 光、酸素または湿気から保護可能なビーズ、
d. 好ましくは動物由来の(乳製品を含む)賦形剤を有しないビーズ、
e. 一般的で単純な方法および設備を用いて簡便に製造可能なビーズ、
f. 魅力があり、一様に球体の外観を有するビーズ。
