METHOD FOR REFINING HIGH-PURITY DILUTED BAMBOO CHARCOAL VINEGAR AND MATERIAL IMMERSED IN HIGH-PURITY DILUTED BAMBOO CHARCOAL VINEGAR

摘要

PPROBLEM TO BE SOLVED: To provide a method for producing a high-purity diluted bamboo charcoal not causing reduction of antimicrobial, sterilizing, deodorizing and antioxidative effects by active ingredient while reducing characteristic odor which a stock solution of bamboo charcoal vinegar has as much as possible without causing complication and enlargement of production facility and increase of production steps. PSOLUTION: In a method for refining a stock solution of bamboo charcoal vinegar comprising cooling discharged smoke produced when producing bamboo charcoal by heating a bamboo material, high-purity water is added to the stock solution of bamboo charcoal vinegar to dilute the stock solution to 80-150 times. As a result, the liquid is separated into an impurity layer 2a in the lowest part, a high-purity diluted bamboo charcoal vinegar layer 2b in the intermediate part and a oil membrane 2c in the uppermost part and only high-purity diluted bamboo charcoal vinegar is taken out to refining the high-purity diluted bamboo charcoal vinegar.
