| abstract |
The invention relates to astaxanthin compositions for use in food, food supplements or animal food or as a medicament. Astaxanthin compositions, which contain at least 50 wt%, in particular at least 60 wt%, more particularly at least 70 wt%, especially at least 80 wt% or at least 90 wt%, by weight. Total astaxanthin and astaxanthin derivatives in the composition, an astaxanthin monoester having an unbranched c10-c22 monocarboxylic acid, has a particularly high bioavailability, if at least 90% by weight of the monoester contained in the astaxanthin composition is a monoester with exactly one unbranched c10-c22 aliphatic monocarboxylic acid. They are therefore particularly suitable for use in food, food supplements or animal feed and for therapeutic use as a medicine and as an ingredient for medical preparations or pharmaceutical agents. |
