Abstract
ABSTRACT This study sought to produce a functional drink using green tea and ginger extracts. The mixing ratios used for the Tea- Ginger blends are: Tea 100% (T1), Ginger 100% (G1), TeaGinger 50%: 50% (T1G1), TeaGinger 33.33%: 66.67% (T1G2) and TeaGinger 66.67: 33.33 (T2G1). The assays carried out include Total Phenols Content (TPC), Total Flavonoids Content (TFC), Condensed Tannins Content (CTC), FRAP Assay, ABTS Radical scavenging assay, %DPPH Radical scavenging assay and Plasma Protein Carbonyl Concentration (PC). Results obtained shows that G1 exhibited the lowest antioxidant property for %ABTS, and FRAP. T1 and T1G2 exhibited the highest antioxidant property for %DPPH and PC, while G1 and T2G1 exhibited the lowest effect for %DPPH, and G1 & T2G1 exhibited the lowest effect for PC. T1 exhibited the lowest antioxidant effect for CTC, while the other samples exhibited high antioxidant effect for CTC. G1 and T2G1 exhibited lowest antioxidant effect for TPC, while T1G2 and T1 exhibited the highest effect. T1 exhibited the highest effect for TFC, while G1, T1G1 and T2G1 exhibited the lowest effect. This study contributes to a better understanding of how a combination of potentially anti-oxidative food materials like tea and ginger might influence the potency of the product.
