| Abstract: | The effect of plucking time on quality of Changxing Zisun tea prepared from cultivar Baiye No. 1’ was studied. The quality of dry tea appearance and infused leaf decreased with extension of pluck in the spring season. However,the liquor taste,aroma and liquor color were better on second-week and third week of plucking. The concentrations of caffeine and water soluble solids were stable during the spring season. Concentration of tea polyphenols increased with pluck time,but that of amino acids decreased with plucking time. |
| Keywords: | Cultivar Baiye No 1 picking and processing time Changxing Zisun tea quality |
