Embodiment Construction
[0038] The food simulants involved in this embodiment are: water, 3%W / V acetic acid, 4%V / V acetic acid, 10%V / V ethanol, 20%V / V ethanol, 50%V / V ethanol, 95% ethanol.
[0039] The method for determining the migration of bisphenol S in plastic food packaging materials comprises the following steps:
[0040] Step 1: Prepare standard working solution, food simulant test solution and blank test solution: the standard working solution is a standard working solution with seven concentrations prepared from bisphenol S; the food simulant test solution is made of plastic food packaging materials and food The simulants are obtained through migration experiments according to the test conditions of GB / T 23296.1-2009 or EU 82 / 711 / EEC and 85 / 572 / EEC, including various common food simulants and oily food simulants; the blank test solution is Food simulants not in contact with plastic food packaging materials.
[0041] The preparation methods of each standard working solution are as follo...
