The present invention provides a process for the dearomatizing and subsequent rearomatizing of black or green tea, wherein (a) the volatile aroma components are removed from the moist tea witha moist inert gas at a temperature of from 60°to 95°C. by means of a carrier gas distillation, (b) the water is selectively removed from the moist, inert gas stream containing the volatile aroma components and (c) subsequently, for rearomatizing, the volatile aroma components are passed through dry tea to be aromatized with the dry inert gas stream.
A process for the dearomatising and subsequent re-aromatising of black or green tea comprising (a) removing the volatile aroma components from moist tea with a moist inert gas with a relative moisture content of 80-95% at a temperature of from 60°to 95°C. by means of carrier gas distillation, wherein at temperatures above 80°C. a contact zone with copper surfaces is used, (b) selectively removing the water from the moist, inert gas stream containing the volatile aroma components and (c) subsequently passing the volatile aroma components through dry tea a...
