Abstract: Fermented enzyme is a kind of functional liquid or solid which are produced by probiotics to ferment one or more fresh vegetables,fruits,mushrooms,Chinese herbs,etc. Due to the rich contents of enzymes,vitamins,trace elements,amino acids,lipids and polyphenols and other nutrients,it has attracted the attention of domestic and foreign researchers and has great potential for development. Status of enzyme products at home and abroad,and the functions of enzymes that promote blood circulation and metabolism,regulate acid-base balance,resist oxidation,fight against fatigue,and contribute to human health were summarized in this research. The production process and application fields were reviewed,and the prospects for the future development of functional enzymes were put forward in order to provide reference for the efficient development of functional enzyme products.
