采用离子色谱检测肉及肉制品中多聚磷酸盐
Determination of polyphosphates in meat and meat products by ion chromatography
摘要
Abstract
A rapid and accurate method for simultaneous determination of orthophosphate,pyrophosphate,tripolyphosphate and trimetaphosphate in meat and meat products were developed by using ion chromatography (IC).The limitation of the detection,the quantification and the best linear range of the method were determined;the standard recovery and precision were also found,and the effect of the actual application was evaluated.Four kinds of phosphates can be easily separated and the limits of detections (LODs) were 0.01,0.15,0.15,and 0.15 mg/L for orthophosphate,pyrophosphate,tripolyphosphate and trimetaphosphate,respectively.The limitation of quantifications (LQDs) were 0.05,0.5,0.5,0.5 mg/L for orthophosphate,pyrophosphate,tripolyphosphate and trimetaphosphate,respectively.The average recoveries of spiked samples were between 83.2％-101.9％,with the relative standard deviations (RSD) less than 2.02％.Meat and meat products in the market were detected using this method.The method is convenient,fast and accurate,and can be applied for the rapid and accurate detection of polyphosphates in different kinds of meat and meat products.关键词
