Abstract:Taking three or four leaves of the bud of Wuyishan Dahongpao as raw materials，using Wuyi rock tea production technology，compared the effects heating with charcoal fire and heating unit on the environment and biochemical composition changes of Dahongpao in the process of Green-making.The results showed that the temperature and CO2concentration of the Green-making room heating with charcoal fire were higher than that of the heating unit，and the relative humidity of the two was not different；contrasting the solar-withering leaves to the end of Green-making，there was no significant change in the content of tea polyphenols between the two groups.The content of tea polyphenols in the charcoal Green-making room and heating unit Green-making room were decreased by 11.12% and 23.11% respectively；compared with solar-withering leaves，the content of flavonoids of Dahongpao in the charcoal Green-making room were increased slightly，but decreased significantly in the heating unit Green-making room（P=0.021＜0.05）；the total free amino acids of both groups fluctuated upward.Compared with the solar-withering leaves，the free amino acids of the Dahongpao in the charcoal Green-making room and heating unit Green-making room were increased by 19.55% and 10.75% respectively；the quality of raw tea made in the heating unit Green-making room was better.
