The present invention provides a process for producing a tea extract, which comprises adding an amylase, an enzyme preparation having a polygalacturonase activity of 20000 U/g or more and a cellulase originated from Trichoderma longibrachiatum or Trichoderma reesei to a tea raw material and extracting the desired tea extract from the mixture. According to this process, it becomes possible to extract a tea-leaf-derived cell wall component that cannot be decomposed or extracted by conventional enzymatic tea leaf extraction techniques. As a result, it becomes possible to produce a tea extract which is rich in sweet flavor, robust flavor and "umami" (tasty) flavor and has reduced bitter taste in high yield. |
