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.

Key words: isothiocyanates, hydrolysis, mechanism
