Study of Spiked Recovery Methods for Testing Total Migration of Food Contact Materials Using Water-based Food Simulants
In the total migration test of water-based food simulants of food contact materials,in order to ensure the reliability of the total migration test results,the feasibility of introducing standard recovery as a means of quality control was studied.Firstly,the change of water content of 4 kinds of common inorganic salts after drying,dissol-ving in water and drying was tested.Then,K2SO4 was used as the additive to carry out the additive test for 4 kinds of water-based food simulants,and the total migration was tested in the water-based food simulants by using ac-tual samples.The results show that the additive is feasible.
