How to produce EGCG powder?
|
|
The present invention of EGCG powder is directed to a process for producing epigallocatechin gallate (EGCG), which includes the steps of: a) providing a green tea extract; b) Subjecting the green tea extract to chromatography on a macroporous polar resin at a temperature in the range of about 10° C. to about 80° C.; c) eluting EGCG from the macroporous polar resin with a polar elution solvent at a temperature in the range of about 10°C. to about 80°C. and at a pressure in the range of about 0.1 bar to about 50 bar; d) optionally concentrating the eluate of step c); e) optionally regenerating the macroporous polar resin by desorbing the remaining catechins; and f) optionally concentrating the desorbed catechins of step e) |
