ABSTRACT

The extraction of bioactive compounds from fruits of green coffee (Coffea canephora) was performed using solid-liquid percolation process and hydroethanolic solvent, by way of a 22 central composite rotatable design (CCRD) and response surface methodology (RSM). Bioactive contents and yield of process were the dependent variables assessed. The process yield was 25 ± 1.2%, 5-CQA, caffeine and trigonelline contents were 9751 ± 274, 6822 ± 127, 2664 ± 118 mg/100 g, respectively. The bioactive contents and reducing capacity in GCFE remained stable for 180 days at 40°C, which suggests its potential application in the pharmaceutical and food industries as an ingredient.
