摘要:
The present invention relates to a stable astaxanthin-containing powdery composition which is obtained by drying a suspension containing a ground Haematococcus alga containing astaxanthin, a surfactant, an antioxidant, an excipient and water and to a process for preparing the same.According to the present invention, there can be provided an astaxanthin-containing powdery composition wherein astaxanthin present in Haematococcus alga has been efficiently stabilized to improve its storage stability for a long term and which is excellent in flowability as a powder, easy to handle and can be easily subjected to solvent extraction without degrading the astaxanthin.

摘要:
A tocotrienol-containing powder prepared by a process wherein an oil containing a tocotrienol is treated with a lecithin, a cellulose and an emulsifying agent in water to form an emulsion, a powder substance is mixed with the formed emulsion to form a suspension and then the formed suspension is spray-dried. The powder containing tocotrienol, which has excellent storage stability and free flowability, can be used in preparing a tablet which comprises the powder compressed into a tablet form.
