Research on the Necessity of Adjusting the Standard Water Extract Indicators of Bohea Tea
The water extract content is an important indicator for evaluating the quality of Bohea tea.The implementation standard of Bohea tea DB35/T 1228-2015 requires that the water extract content of Bohea tea must be≥33%.However,in the actual testing process,it was found that some Bohea teas,especially ecological black teas without fertilizer or pesticide,had unqualified water extract content,reflecting that the water extract index in the standard was too strict.This study compared the water extract index in different black tea product standards,tested the water extract content of different grades of Speciad Red,Lapsang Souchong and Souchong black tea,and analyzed the distribution range and reasons of unqualified water extract content of Bohea tea.It is recommended that the water extract index of Bohea tea be adjusted to≥30%.
