Incorporation of catechin extracts from gambier products and pasak bumi in the production of functional instant green robusta coffee

2022

The research was used to produce functional instant green coffee through gambier catechin extract and pasak bumi powder. This involved using a non-factorial completely randomized design with 5 treatments and 3 replications. The treatments consist of 5 formulations (F), including the instant green coffee (%), gambir catechin extract (%), and pasak bumi powder (%) where F1 was at 100:0:0, F2 was 80:15:5, F3 was 70:20:10, F4 was 60:25:15, and F5 was 50:30:20. The results showed the functional instant green coffee produced has a water content of 3.84 – 4.81%, soluble speed of 26.78 – 29.33 seconds, and total phenol of 16.79 – 169.48 mg/L, and IC50 of 44.68- 207.59 ppm. The addition of gambier catechin extract and pasak bumi powder to the formulation was observed to have significantly increased the functional properties and water content. Moreover, the soluble speed of the instant coffee fulfils the quality requirements of the Indonesian National Standard (SNI) number 2983 of 2014.
