The authors investigated the moisture absorbing properties of tea with the object how to. stock the tea completely. This paper reports the influence of polishing process upon the hygroscopic property of tea, comparing the moisture absorption of polished tea with the unpolished one in a thermostat (30°C, 100% relative humidity).
By the result of this experiment, the moisture absorption of the polished tea was always less than the unpolished, in all types of tea examined.
The moisture absorption velocity was faster at the beginning but it slowed down gradually as the moisture content of the tea increased.
