A process for the enzymatic treatment of black tea leaf is disclosed. In particular, black tea leaf is wetted with water containing tannase and one or more cell-wall-digesting enzymes, such as cellulase, pectinase, papain, or hemicellulase, prior to extraction. The enzyme-moistened tea leaf is incubated in a closed system at room temperature for a few hours. The enzyme-treated tea is then neutralized with a suitable food grade base and the enzymes are inactivated by heating. The resulting treated tea can be extracted and processed in the usual manner or ...


A process for increasing the yield and tea solid solubility of black tea by enzymatic treatment, comprising the steps of: (1) wetting fermented black tea leaf prior to extraction with an enzyme solution comprising water, tannase and at least one cell-wall-digesting enzyme which breaks down one or more tea cell wall constituents to simpler materials wherein the tea leaf is combined with the enzyme solution at a tea:enzyme solution weight ratio of from about 4:1 to about 1:2.5; (2) incubating the enzyme-wetted tea to cause partial digestion and fermentati...
