Antibacterial activity of coffee extracts and selected cofee chemichal ekstrakai against Enterobacteria. The developed mathematical model can be used in designing single column reactor for coffee decaffeination process, to predict decaffeination time and rate, and decaffeination process in optimum condition using acetic acid, effluent of fermented cocoa beans, and tertiary solution of fermented cocoa pulp.

For coffee consumers who have high tolerance for caffeine, coffee may warm up and refresh their bodies.

The general objective of this research was to optimize decaffeination process of robusta coffee in single column reactor with leaching method. A simple mathematic model kafeiin caffeine kinetic description during the extraction process leaching of coffee bean was developed.

Mathematical model validation was checked by comparing prediction time t-predict versus observation time t-obsr.
