This study explored the optimization of extraction condition of total polyphenols and flavonoids from dried coffee cherry pulp (Cascara) by response surface methodology. The effect of varying the extraction conditions such as solvent (water)-to-material ratio (X1); temperature (X2) and time (X3) were studied. The results demonstrated that the best combination of extraction conditions for dried coffee cherry pulp was at 1: solid-solvent ratio, oC and min. At optimal extraction conditions, the total polyphenols content achieved mg GAE/g and total flavonoids achieved achieved mg QE/g, on a dry basis. | Optimization of conditions of extraction process from coffee cherry pulp (Cascara) and application to drinking water product with antioxidant activity
