Methods The samples were extracted with methanol- saturated n-hexane. The supernatant were separated by polar HP-5MS capillary column and analyzed by GC-MS after filtering through 0.45 μm membrane filter. Results The amount of migration of DBP and DnOP increased with the initial package temperature increasing. The amounts of migration of DBP and DnOP were 0.70 mg/kg and 0.16 mg/kg respectively in fritter samples which were packaged at 200 and then stored at room temperature for 60 min. The amount of migration of DBP and DnOP increased with the storage time prolonging after samples were packaged at 200 initial temperature. The amounts of migration of DBP and DnOP in fritter samples which were packaged at 200 and then stored at 25 for 48 h were 0.79 mg/kg and 0.24 mg/kg, respectively. The amounts of migration of DBP and DnOP in fritter samples which were packaged at 200 and then stored at 4 for 48 h were 0.63 mg/kg and 0.15 mg/kg, respectively. The amounts of migration of DBP and DnOP in the samples which were stored at 4 * 通讯作者 :,, E-mail: baiyanhong@zzuli.edu.cn *Corresponding author: BAI Yan-Hong, Associate Professor, College of Food and Biological Engineering, Zhengzhou University of Light Industry, No.5, Dongfeng Road, Zhengzhou 450002, China.

1062 4 were lower than that at 25. Conclusion The maximum amounts of migration of DBP and DnOP occurred in the skin of fritters which were directly contacted the packaging materials, and then migrated to the food inside. There was a potential hazard for the health of consumers because of the migration of DBP and DnOP.
