Investigation on decoloration of Zanthoxylum Bungeanum seed oil

摘要

The decoloration method experiment on ZSO was studied. The different influencing factors on reaction were investigated by single test, such as content of peroxide, reaction temperature, and reaction time. The results of orthogonal test showed that the dominated sequence of influencing on chroma value was content of peroxide, and then was for reaction temperature, the last was reaction time. The optimal combination proved was A2B2C2. On this condition, the chroma value of ZSO could be reduced to 1.45, it fully meets the requirement of industrial application.
