MINUMAN FUNGSIONAL DARI KOMBINASI KOPI ROBUSTA (Coffea canephora) DAN EKSTRAK GAMBIR (Uncaria gambir Roxb.)
Daftar Isi:
- The objective of this research was to investigate the effect of robusta coffee and gambir ekstract ratio on physical, chemical and sensory characteristics of functional drink. The experiment was conducted at Chemical of Agricultural Product Laboratory and Sensory Laboratory at Departement of Agricultural Technology, Faculty of Agriculture, Sriwijaya University, from September to November 2019. This research used a non factorial completely random design, namely ratio of robusta coffee and gambir addition. The treatment has the following levels : 100% robusta coffee : 0% gambir extract ; 95% robusta coffee : 5% gambir extract ; 90% robusta coffee : 10% gambir extract ; 85% robusta coffee : 15% gambir extract ; 80% robusta coffee : 20% gambir extract. The experiment was conducted in triplicates. The observed parameters were physical (solubility percentation), chemical (antioxidant activity, pH, and total phenol), and sensory characteristics. The results showed that ratio of coffee and gambir had significant effects on solubility percentation, antioxidant activity, pH and total phenol. The best treatment was 90% coffee and 10% gambir ratio with the following characteristics : solubility percentation 28.42%, antioxidant activity 50.48 ppm, pH 5.48, total phenol 67.11 mg/mL, taste 3.24, color 3.00 and aroma 2.98.
