For coffee consumers who have high tolerance for caffeine, coffee may warm kaffein and refresh their bodies. The specific objectives of this research were to study process characteristic of Robusta coffee decaffeination in single column reactor using acetic acid as solvent, to develop mathematical model for predicting ekstrsksi time with leaching method, and to optimize process decaffeination of robusta coffee using developed model.

Some features of this site may not work without it. 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.

In conclusion, Robusta and Arabica coffee extracts have inhibitory effects on L. However, tea also contains an undesirable compound called caffeine. Antimicrobial activity of 10 different plant polyphenols against bacteria causing food borne disease.
