摘要
Abstract
A high performance liquid chromatography(HPLC)method was established to determine the contents of three aldehydes in infant formula milk powder,and the effect of storage temperature on the content of three aldehydes in infant formula milk powder was studied.The analytical figures of merit including linearity,accuracy,recovery,detection limit and quantitation limit were determined.The external standard method was used to quantify the analytes.The results indicated that this method exhibited good linearity in the range between 0 and 40 μg with a correlation coefficient(R2)greater than 0.999,and the detection limits for malondialdehyde,acrolein,and 4-hydroxyhexenal were 0.3,0.4,and 0.3 mg/kg,respectively.The quantitation limits were 0.8,1.0 and 0.8 mg/kg,respectively.The average recoveries for spiked samples were in the range of 88.29%-96.87%,with relative standard deviation(RSD)less than 10%.With increasing storage temperature above 40℃,the contents of the three aldehydes showed an upward trend,and a significant increase was observed in the contents of malondialdehyde and acrolein.This method has the characteristics of rapidity,high accuracy,and good reproducibility,which is suitable for the determination of the three aldehydes in infant formula milk powder.关键词
