  • Publication number: 20080131558
    Abstract: Provided is a process for producing a product enriched in theaflavins. The process comprises contacting a first and a second material to form a reaction mixture with a specific weight ratio of catechins to theaflavins, fermenting the reaction mixture, and then recovering the product from the reaction mixture. The process is particularly suitable for producing leaf tea products with high levels of theaflavins.
