Allyl Isothiocyanates (AITC) is a degradation product of thioglycoside in the red cabbage pigment extract, which limits the industrial applications of red cabbage pigment extract. In order to solve this actual production problem, the process and possible mechanism of removing AITC using high pressure carbon dioxide (HPCD) under different pressures and temperatures are analyzed with the AITC solution as experimental material. The results show that the removing process of AITC using HPCD follows the first-order kinetics model. Pressure is a non-significant factor (P>0.05) for the removing rate and half-life period, which indicates that the treatment pressure has little influence on the removing of AITC. Elevating treatment temperature can improve the removing rate of AITC nearly twice, and also shorten the half-life period, which indicates that the treatment temperature has more influence on the removing of AITC. The significant effect of the thermal degradation during the removing process of AITC by HPCD is verified by the further analysis.
