Title:
PROCESS FOR PRODUCING TEA EXTRACT
Document Type and Number:
WIPO Patent Application WO/2012/046349
Kind Code:
A1
Abstract:
The present invention provides a process for producing a tea extract, which comprises adding a protease, a tannase 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, a tea-leaf-derived cell wall component that cannot be decomposed or extracted by conventional enzymatic tea leaf extraction techniques can be extracted, and a protein of which the extraction becomes possible through the success of the decomposition of the cell wall component can be further decomposed into an amino acid. As a result, it becomes possible to produce a tea extract which contains an amino acid component in abundance and is rich in sweet flavor, robust flavor and "umami" (tasty) flavor in high yield.
