A large amount of impurities in shochu were removed with an anion exchange resin (Amberlite IRA-410) in the bisulfite form. Especially, acetaldehyde, furfural and acids were completely removed, and fusel oil was removed about 40% owing to resins's adsorption activity. In this treatment the test was prevented from mingling of HSO_3^3 by the use of an anion exchange resin in the hydroxy form. The improved quality of so treated shochu was demonstrated by means of the BARBET reaction and spectrophotometric analysis using BECKMAN-type spectrophotometer. B-type shochu (distilled by pot still) was improved markedly and showed nice characters like A-type (distilled by continuous column) in sensory test.Unremoved impurities occurring in every kind of shochu showed a peak of absorption within the range of wave length 260〜280 mμ.
