Abstract

This essay provides a physical method to improve the “aging” process of Yunnan Pu’er tea, which is pollution-free, energy saving and having no negative effect on the taste or nutrition facts of Pu’er tea. “Aging” is a special storage method in the culture of Yunnan Pu’er tea. After stored for a certain period of time, the aroma and taste of Pu’er unfermented tea would become favorable for drinkers. In addition, as the elevation of people’s living standard and the gradual acknowledgment of Pu’er tea’s salutary effect, the demand of Pu’er tea increases drastically in recent years. Its characteristic that “getting better” becomes the factor attracting consumer and guiding market price. This essay utilized high-intensity pulsed electric field (HPEF) to process tea samples under different conditions. The results of experiments show that both the taste and aroma of tea samples have improved after the process. This result provides a new method to elevate the quality of Pu’er tea and a theoretical basis for artificial aging of Pu’er tea by HPEF.
