Analysis of Quality Differences Between Albino Tea in Different Picking Period
The picking period of tea was closely related to the quality of tea.Green tea was prepared from Baiye.1 fresh leaf at different picking periods under the same processing technology,and the physicochemical compo-nents of tea polyphenols and catechins were analyzed.The results showed that the contents of tea polyphenols,free amino acids and flavonoids of the delayed albino tea increased first and then decreased.The content of caffe-ine showed an increasing-decreasing-increasing trend,and the content of soluble sugar showed a decreasing trend.The total amount of catechins showed significant difference in different picking periods,as follows:April 12＞A-pril l＞April 17＞April 22＞April 6.The albino tea picked on April 6 showed high content of free amino acids and low content of tea polyphenols,and other contents were rich.The quality of the green tea was good.The con-tent of physical and chemical components of albino tea at different picking stages was different,which affected the quality of the finished tea,and the quality of albino tea made from fresh leaves on April 6 is better.
