For the analysis and discussion of different process concepts,
especially the equilibrium and mass transport kinetic is considered. The fundamentals of enhancements are discussed employing
particle size distribution and SEM measurements.
The laboratory experiments are carried out with black tea from
Kenya. As extracting solvent pure ethanol as well as a mixture consisting of ethanol/water 90/10 (m/m) are used. The total content of
polyphenols is quantified by five stage maceration (each 24 h), fol
