REMOVAL OF UREA FROM ALCOHOLIC LIQUORS |
摘要 |
Alcoholic liquors containing carbamide are treated with the urease which has the optimal pH for the activity in an acid region, especially in the region of pH 2 to 5. By such treatment, the carbamide can be completely decomposed and removed from the alcoholic liquors in a much smaller amount of urease and in a short time as compared with the conventional treatment according to a urease having the optimal pH in the neutral to alkaline region. This method is mor e advantageous from the viewpoint of practical use and the quality of the thus obtained alcoholic liquors are superior to that obtained by the conventional treatment. |
