| The main source of natural astaxanthin is Haematococcus pluvialis. Astaxanthin has been widely used in food, aquaculture, cosmetics and pharmacy industries for its good capability as antioxidant and coloring agent. However, the currently commercial products of astaxanthin can not meet the needs of diversified applications, due to its drawback of low water solubility and chemical instability. In recent years, a lot of new technologies in pharmaceutics have been applied to develop new commercial products of astaxanthin, and the commercial product of astaxanthin enriched to a certain extent.The advances in preparation technologies of astaxanthin were summarized. Aiming at the effects of traditional astaxanthin preparation technology, new astaxanthin preparation technology(astaxanthin micro/nanoparticles, astaxanthin water dispersion system, astaxanthin supramolecular aqueous solution) and packaging technology of astaxanthin preparations on stability of astaxanthin, the research results of raw material, preparation and preservation of astaxanthin were introduced, in order to provide theoretical support for development of new astaxanthin commercial products with better preservation ability, chemical stability and bioavailability. |
