摘要: 本文研究了温度、pH值、溶剂、超声波等因素对辣根油中异硫氰酸酯水解稳定性的影响。结果显示随着温度的升高异硫氰酸酯水解速度加快;在丙酮溶液中异硫氰酸酯性质稳定;在超声波条件下异硫氰酸酯水解速度极快。同时,我们讨论了异硫氰酸酯的水解机理,并提出了一种提高其稳定性的方法。

Abstract: In this study, the effects of temperature, pH, solvent, ultrasonic wave on the hydrolyzation of isothiocyanates in the volatile oil of horseradish were investigated. The results indicated that the hydrolytic rate increased with the rising of temperature; isothiocyanates were stable in acetone and the hydrolytic rate was very high by ultrasonic wave. In addition, the mechanism of the hydrolyzation was discussed and a method for improving its stability was also given.
