Gayo coffee processing with natural, semi-washed and full-washed methods

Abstract

Gayo area is the largest Arabica coffee production in Asia. The materials used in this research were coffee beans which are natural, semi-washed, and fully-washed processed coffee. This study aimed to determine the physicochemical of green bean will the various processing. The moisture content of three green bean coffee were 9.78%, 9.60% and 11.03% for natural, semi-washed and full-washed processing, respectively. The ash content ranged from 3.19% for natural processing to 4.33% for full-washed processing. Full washed green bean coffee had the highest lipid content, 12.5 ± 0.20% compared to the other coffee. Moreover, the lowest pH and specific volume were found in natural processing coffee, 5.63 and 1.66 mL/g, respectively. The finding result shows that coffee characteristics depending on the processing methods. Future work will be done by applying various packaging for the coffee bean.
