A large number of studies have proved that astaxanthinhas potential special health effects in the human body, making astaxanthin more and more popular.
At present, the main sources of astaxanthin include chemical synthesis and natural extraction. Chemically synthesized astaxanthin is different from natural astaxanthin in terms of structure, properties, application and safety. The efficient extraction and preparation of astaxanthin is the focus of the future development of astaxanthin, especially the use of yeast, algae and other microorganisms to industrially ferment astaxanthin, which has a short production cycle and broad prospects. wide. Therefore, screening high-yielding strains, improving the fermentation process, introducing genetic improvement technology in a timely manner, increasing yield and reducing costs will greatly contribute to the further development and application of astaxanthin. The application of astaxanthin in the field of functional foods mainly focuses on strengthening immunity, anti-cancer, anti-aging, protecting retina, anti-inflammatory, preventing oxidative damage of blood low-density lipoprotein cholesterol (LDL-C), etc. A lot of health and nutritional foods and dietary supplements containing astaxanthin have been produced, which have excellent application prospects and far-reaching development significance.
