A novel method for simultaneous determination of total specific migration limits(SML(T))of 9 antioxidants(Ni?pa 49(CAS:121-79-9),Stabilizer GA-8(CAS:1034-01-1),Progallinla(CAS:1166-52-5),RC 1726(CAS:110675-26-8),AO 1520(CAS:110553-27-0),Ionox wsp(CAS:77-62-3),ZKF(CAS:4066-02-8),AO 425(CAS:88-24-4)and AO 2246(CAS:119-47-1))in food simulants was developed by high performance liquid chromatography(HPLC)with ul?traviolet detector. After the migration test,the soaking solution was cooled down,and vortexed. Each type of aqueous food stimulant(10%ethanol,3%acetic acide,20%ethanol or 50%ethanol)was diluted with tetrahydrofuran with 0.05%tris-(2-carboxyethyl)-phosphine hydrochloride(TCEP),and the fatty food simulant isooctane was concentrated by 10 times,and then a filtration was performed with a disposable syringe and hydrophilic polytetrafluoroethylene before injection. The SunFire TM C8 column and gradient elution mode were selected;the detector was set at 285 nm. The limits of quantification were between 0.005~1.0 mg/L;the linearity of the method was good with r2>0.9982 over the concentration range from 30-720,5-120,3-72 or 1.5-36 mg/L for isooctane,and 3-72,0.5-12,0.3-7.2 or 0.15-3.6 mg/L for aqueous food simulants;The recoveries of nine antioxidants were between 83.7%and 113%with the relative standard deviation between 0.8%and 11.2%at the level range of 0.3-84mg/L. The method shows the lower limits of quantifacations,good recoveries and accuracies,and met the requirement of(EU)NO 10/2011 regulation for the to?tal specific migration limit of nine antioxidants. The method has been applied to analyze food contact material samples.
