| titleOfInvention | The method that gas chromatography measures 5 kinds of antioxidant the amount of migration in packaging material |
| abstract | The invention discloses the methods of 5 kinds of antioxidant the amount of migration in a kind of gas chromatography measurement plastic food packaging materials, it is after plastic food packaging materials to be measured are prepared into small plastic bag, it is cleaned with distilled water, it dries, then aqueous-based food simulated solution and oil-based foods simulated solution are respectively charged into small plastic bag, are contacted under certain condition；Then the aqueous-based food analogies soak of acquisition is prepared into aqueous-based food analogies prepare liquid after liquid-liquid extraction is handled, oil-based foods analogies prepare liquid is prepared into after oil-based foods analogies soak is directly filtered, machine measurement is carried out respectively, to obtain the amount of migration of 5 kinds of antioxidants in plastic package material to be measured.Experiment proves that the method for the present invention is more satisfactory to the rate of recovery and relative standard deviation of water base analogies and oil base analogies, and have the characteristics that easy to operate, accuracy is high, is detected while 5 kinds of antioxidant the amount of migration suitable for plastic food packaging materials. |
