PROCESS FOR THE DECAFFEINATION OF TEA

摘要

Process for the decaffeination of tea The present invention provides a process for the decaffeination of tea containing 15 to 50% by weight of water with moist carbon dioxide at 255 to 350 bar and at 50 to 80.degree.C. in an autoclave, subsequent separation of the caffein from the carbon dioxide with the help of an adsorbent and recyclising the caffein-free carbon dioxide over the already extracted tea, wherein the adsorbent is distributed in the material to be extracted in an amount of from 5 to 40% by weight, referred to the dry weight of the tea.
