Drops of malodorous substances (isovaleric and propionic acid) were put into separate test tubes, glass wool inserted, and 1 g of Shonai Kaki Powder added.
After heating the test tubes for a ﬁxed period, the quantities of malodorous substances in the gas phase were determined by gas chromatography, and thepercentages of substance remaining and deodorization rates calculated.
These values were compared to those for controls with no powder added. The results show a deodorizing eﬀect of 75% for isovaleric acid and 70% for propionic acid.
