摘要

在高脂肪食品用塑料包装的全球迁移试验中，采用三庚酸甘油酯(GTM)作为气相色谱法定量脂肪酸甲酯(FAMEs)的内标。以3-苯基丙酸乙酯(EFP)和十四烷酸(AM)作为备选内标进行了评价。(AM)的使用呈现线性行为(r = 0.99， %Sb < 5%)，良好的中间精度(HORRATr = 0.9)和准确度(% r = 100.6%)。相比之下，EFP的评价表明，这不是一个适当的内部标准，以定量的FAMEs。此外，统计评估表明，使用GTM或AM作为内部标准量化的FAMEs的全球迁移计算没有显著差异，但使用EFP存在显著差异。

Ensayo de migración global en empaques para alimentos: evaluación de patrones internos alternativos

In the global migration test for plastic packaging intended for fatty foods, glyceryl triheptadecanoate (GTM) is used as the internal standard for the quantification of fatty acid methyl esters (FAMEs) by gas chromatography. In this work, ethyl 3-phenyl propanoate (EFP) and tetradecanoic acid (AM) were evaluated as alternative internal standards. The use of (AM) presented linear behavior (r > 0.99 and %Sb < 5%), good intermediate precision (HORRATr = 0.9), and accuracy (%R = 100.6%). In contrast, the evaluation of (EFP) demonstrated that this is not an adequate internal standard for the quantification of FAMEs. In addition, it was statistically evaluated that there are no significant differences in the calculation of the global migration from FAMEs quantified using GTM or AM as internal standards, but the use of EFP presents significant differences.
