Abstract |
Influence of water quality on the green tea extraction and their constituents was studied. The concentration of the catechins, L-theanine and theaflavins was higher in the water containing lower total dissolved solids, conductivity and pH. The total phenolic content and FRAP values was also determined respectively. The extractability difference was explained using the mass transfer equation. The whole process was carried out in the High-performance liquid chromatography (HPLC). By the study it is recommended to use the water having lower TDS, conductivity and pH for hot infusions and RTD beverages. |
