| Research Abstract |
The purpose of this study is to develop the deodorant denture. The deodorant used was silica gel and mixture of silica gel and alumina which were adsorbed green tea extract. A gas chromatograph was applied to the determination of methyl mercaptan in head-space gas, which was taken out of glass bottle holded both the deodorant denture plate and methyl mercaptan.
The resin plate contained 1wt% of deodorant had deodorization superior to that contained 3wt% of deodorant. The deodorization didn't contained for many days. The green tea extract had antibacterial activity.
