Research Progress on Preparation and Analysis Methods of Ergothioneine
Ergothioneine is a natural antioxidant,which is only synthesized by fungi,cyanobacteria and other microorganisms.It can be ingested and accumulated by the human body from food.As a natural active substance,which can effectively remove free radicals,chelating bivalent metal cations,etc,it can be used in various fields such as medicine,health food and cosmetics.However,at present,ergothioneine is expensive and its preparation and purification technology is not enough.In order to provide a reference for the green,economical and efficient production of ergothioneinethe,the progress in the preparation,separation,purification and analysis methods of ergothioneine in recent years was reviewed in this paper,and the hot spots and difficulties in the research were summarized and prospected.
