Abstract
The deodorizing effects of tea leaves and used tea leaves were evaluated. Absorption capacities of sencha (Japanese green tea), hojicha (Japanese roasted tea), oolong tea and black tea for hydrogen sulfide, methyl mercaptan, toluene and ammonia were determined. These tea leaves were found to absorb small amounts of toluene and negligible amounts hydrogen sulfide and methyl mercaptan, but were very effective in absorbing. No correlation was found between the catechin concentrations of the tea leaves and their absorption capacities.
