婴幼儿配方谷粉中多组分反式脂肪酸的同步测定
Synchronous detection of multicomponent trans-fatty acids and investigation of content in infant formula farina
摘要
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 commer-cial 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 C18:1-11T,C19:1-7T,C18:3-9T/12T/15T,C18:1-9Tand C18:2-9,12TT.Moreover,we found that the ingredient formula and pro-cessing technology were two main factors that could fluctuate the TFAs content in infant formula farina.关键词
