A method for the determination of acrylamide in sugar by RRLC-/MS/MS was established.After sample extracted with ethyl acetate and concentrated,it was analyzed by RRLC-MS/MS.Determinations were performed by using electrospray ionixation(ESI+) and multi-reaction monitoring(MRM) modes.Internal standard of 13C3-acrylamide was used in the quantification.The linear range of the method was 10~200 ng/mL,the recoveries were 100.5%~108.1%,the detection limit was 10 μg/kg and the relative standard deviations(RSD)was ≤5.67%.
