Adsorption deodorants, masking deodorants, etc. are common. The chemical deodorant is a deodorant that is produced by converting a generated malodorous substance into a non-malodorous substance by oxidation, reductive decomposition, neutralization reaction, addition reaction, condensation reaction, ion exchange reaction, or the like. The microbial deodorant is a process of absorbing malodorous substances in dissolved water into microorganisms by utilizing the microorganisms and degrading the malodorous substances through the metabolic activity of the microorganisms. The plant type deodorant is based on the principle that natural plants have the function of purifying the environment, and by analyzing the components of the malodorous gas in the farm, plant types capable of eliminating the molecules of the malodorous gas are searched.
