title: [Study on odor control using wood vinegars].
abstract: The effectiveness of wood vinegars reducing or eliminating offensive odors, associated with cattle breeding, was studied. The results obtained were as follows: 1. Analyzed were 0.7-7.2% acetic acid and 0.5-1.8% methyl alcohol as main contents. 2. Gaseous odorants, such as ammonia, trimethylamine, n-butyric acid were almost eliminated through absorption using 1-20% wood vinegar solutions. 3. The same gaseous odorants, mentioned above, when confined to an airtight vessel, were eliminated in a short time by adding a little volume of wood vinegars to it. The effect was maintained for 2 weeks. 4. A sensory test was performed to evaluate the degree of deodorization, such as odor intensity and odor acceptability. Results showed that wood vinegars have a good deodorant effect on the offensive odors.
