Theaflavins, which comprise a mixture of theaflavin, theaflavin-3-gallate, theaflavin-3’-gallate and theaflavin-3,3’-digallate, are typically formed via polymerization of green tea polyphenols (i.e., flavanoids) during fermentation of green tea to black tea. Theaflavins are unique active ingredients that are produced when green tea ferments and changes into black or oolong tea. They are responsible for the characteristic color and flavor of black tea.
