Abstract

Abstract: The study aims to explore the effect of temperature on water losing rate of leaves in withering process of Congou black tea to construct a predictive model of changes of water losing rate of leaves. Basic models were developed for 4 temperatures (20, 25, 30, 35℃) with 60%-65% relative humidity (RH), in order to clarify the correlation of time, temperature and leaf water losing rate of the withering. The prediction model of relationship between fresh leaf water losing rate and temperature was built based on chemical reaction kinetics and Allen equation (Arrhenius) (R²＞0.98). An experiment was done to verify correctness of the model and results showed that the predicted values achieved by the model agreed well with field test results (P=4.538%). The model could be used to forecast the law of water losing rate of leaves and determine the time ranges of wilting and had important theoretic value and guiding significance for optimization of the withering process of congou black tea.
