摘要:

建立多组分反式脂肪酸同步测定方法，并对38批市售婴幼儿配方谷粉中各组分反式脂肪酸（TFAs）的含量进行测定。结果显示：婴幼儿配方谷粉样品中TFAs平均含量为0.749 3 mg/g，总体含量较低，约76.3%的样品中TFAs总含量在0.04～1.0 mg/g，主要组分为C_18:1-11T，C_19:1-7T，C_{18:3-9T,12T,15T}，C_18:1-9T和C_18:2-9,12TT，经分析配料配方与加工工艺是影响婴幼儿配方谷粉中TFAs含量的2个主要因素。

Abstract:

In this study, we established multicomponent trans-fatty acids(TFAs) synchronous detection method, and on this basis the content of various components of TFAs from 38 batches of commercial infant formula farina was investigated. The results showed the average content of TFAs in infant formula farina was 0.749 3 mg/g, and the overall content was low. The TFAs total content was within a range of 0.04～1.0 mg/g in approximately 76.3% of samples. The main component was C_18:1-11T,C_19:1-7T, C_{18:3-9T/12T/15T}, C_18:1-9T and C_18:2-9,12TT. Moreover, we found that the ingredient formula and processing technology were two main factors that could fluctuate the TFAs content in infant formula farina.
