Abstract: Immobilized enzyme technology is the central part of enzyme engineering in current time. It has been well known that prolonging the half-life of enzyme, enhancing the stability, the reuse of enzyme and the separation of product and enzyme could be realized by this technology. Tea polyphenol oxidase is an important member of oxidases, it played an important role in tea-processing, tea refining processing and manufacture of tea beverage. The immobilized matrixs include inorganic-matrix, organic-matrix, complex-matrix and nano-matrix. The capability demand of immobilized enzyme matrixs, and various carriers applied to polyphenol oxidase immobilization were summarized in this paper. The nano-carrier with functional groups was regarded as the main matrixs of immobilized polyphenol oxidase in the future by the authors.

Key words: polyphenol oxidase, immobilization, matrix
