BAMBOO VINEGAR AND WOOD VINEGAR AND METHOD FOR REFINING THEM

PROBLEM TO BE SOLVED: To produce bamboo vinegar and wood vinegar where the sterilizing effects and deodorizing effects of crude bamboo vinegar and wood vinegar obtained in the carbonization processes of bamboo and wood have been maintained/improved, and to provide a method for refining bamboo vinegar and wood vinegar so as to fully exhibit their sterilizing effects and deodorizing effects despite being safe. SOLUTION: This method for refining bamboo vinegar and wood vinegar comprises the following process: crude bamboo vinegar and wood vinegar obtained by cooling smoke emitted when plants are put to carbonization treatment are subjected to filtration treatment, the resultant liquids thus treated are adjusted to pH 3-5 and then put to electrolysis treatment; optionally, the electrolysis treatment comprises the following practice: crude bamboo vinegar and wood vinegar are electrolyzed in electrolytic baths 2 with diaphragms 1 through a direct current source 5; the resultant bamboo vinegar and wood vinegar-electrolyzed acid water components are used as the objective refined products; alternatively, crude bamboo vinegar and wood vinegar are electrolyzed in diaphragmless electrolytic baths through direct current, and the resultant bamboo vinegar and wood vinegar thus obtained are used as the objective refined products.
