Resumen

Objective: To evaluate and compare the percentage of mucilage removal from coffee (Coffea arabica L.) in pulping using two enzyme systems, Celuzyme and Macerex PM.


Design/methodology/approach: Seven treatments combinations were evaluated (type of enzyme and concentration level, plus a control) at 30 min intervals for 3 h. The experimental unit was 0.2 kg of pulped coffee.


Results: Results showed when using these enzyme systems (Macerex PM and Celuzyme) the percentage of mucilage removal increased and time was significantly reduced by 3 to 4 h compared to the natural fermentation time of 15 to 20 h.


Limitations on study/implications: Effect of two enzyme systems, Macerex PM and Celuzyme, at different concentrations (mg L-1).


Findings/conclusions: The Macerex PM and Celuzyme enzyme systems showed 95% and 84.5% removed mucilage compared to 35% of the control
