| Abstract: |
| In order to provide a reference for the risk control of Zanthoxylum bungeanum oil processing enterprises and the safety supervision and management of Zanthoxylum bungeanum oil, the pollution status and sources of phthalate plasticizers in Zanthoxylum bungeanum oil were analyzed. The contents of dibutyl phthalate (DBP) and bis(2-ethylhexyl)phthalate (DEHP) in 92 Zanthoxylum bungeanum oil samples were determined by gas chromatography-mass spectrometry and their pollution sources were analyzed. The results showed that there were different degrees of plasticizer pollution in Zanthoxylum bungeanum oil on the present market. The detection rate of DBP was 74.00% and its content was in the range of 0.07-10.59 mg/kg. The detection rate of DEHP was 93.48% and its content was in the range of 0.07-1.86 mg/kg. The over-standard rates of DBP and DEHP were 17.39% and 1.09%, respectively. The detection rate and average content of DBP and DEHP in Zanthoxylum bungeanum oil increased with the increase of amides content.Raw materials and production contact materials were the main pollution sources of phthalate plasticizers in Zanthoxylum bungeanum oil.To sum up, there is plasticizer pollution risk in Zanthoxylum bungeanum oil on the market, the monitoring of raw materials should be strengthened, and plasticizer risk throughout the production and storage of Zanthoxylum bungeanum oil should be controlled. |
