Title FERMENTED TEA DRINK CONTAINING METHYLATED CATECHIN
Abstract Disclosed are a fermented tea drink containing a large amount of methylated catechin and a method of producing the same. A fermented tea drink is obtained by adding water to fresh tea leaves of a black tea variety which contains methylated catechin, milling the mixture in a mixer, incubating the same by allowing to stand for 15 minutes or longer and then removing solid matters therefrom. According to this production method, theaflavins are synthesized without lowering the contents of EGC3" methyl and EC3" methyl during the fermentation procedure and thus a fermented tea drink having a good aroma and sweetness with little bitterness and astringency can be produced.
