Abstract

Abstract: Different withering humidity conditions are set with artificial climate box, the dynamic change of chromatic aberration during withering leaves and its inherent law were investigated. The results showed that, three chroma index L, a, b showed significant changes with the increase of withering time under the conditions of three different humidity treatments, and there were significant differences between different humidity treatments, but its difference was decreased gradually with the increase of the withering time. The law of change of L, a. b and overall color during tea withering process with the conditions of three different humidities were analysed in this investigation. The results showed that 70% humidity was regarded as the optimum humidity in the withering of tea. The results of this investigation provided the reference to the theoretical basis on the changes of physic-chemical properties in tea process.

Key words: humidity, withering leaf, chromatic aberration
