The present invention relates to a process for the development of a highly efficient solid state matrix by the activation of acrylate based polymer resin having specialized functional groups with 1,1-Carboxyl diimidazole for immobilizing biologically active macromeloecules such as oxidases, in particular plant oxidases and the most preferred being tea polyphenol oxidase through indirect covalent bonding/cross linking on such activated polymer resin support, are thermally stable, gives very high number of turnovers in vitro (“n” times) with tea substrate ...
1. A process for converting a tea substrate to theaflavins comprising the steps: a) incubating a mixture of a tea substrate dissolved in water and a solid state matrix, the solid state matrix being of formula III, wherein X is up to about 30, Z is one per carboxyl group in a polymer chain length: E is polyphenol oxidase enzyme (PPO), at a temperature ranging between 25° C. to 37.5° C. for a period ranging between 30 minutes to 2 hour, and b) separating the matrix from the mixture to obtain filtrate containing the product theaflavins and recycling the ma...
