摘要

为了快速分析组胺等8种非挥发性胺，建立了一种简便的分析方法。在LC-MS/MS分析之前，仅将三氯乙酸提取物稀释过滤制备测试溶液。对包括新鲜海鲜、海鲜加工产品和其他加工食品在内的11种食品进行添加剂回收率测试，结果表明，所有胺在9种食品中的准确度在70 - 120%之间，重复性小于15% RSD。验证了该分析方法的有效性，定量下限为5 ~ 6mg /kg。

[A Simple and Rapid Analysis Method for Nonvolatile Amines via LC-MS/MS].

In order to quickly analyze 8 types of nonvolatile amine, such as histamine, a simple analytical method was developed. A test solution was prepared only by diluting and filtering a trichloroacetic acid extract before analysis via LC-MS/MS.As a result of the additive recovery test with 11 types of food, including fresh seafood, seafood processed products, and other processed foods, all amines had an accuracy in the range of 70 to 120% with a repeatability of less than 15% RSD in 9 types of food. This confirmed the validity of the analytical method with the lower limit of quantification between 5 to 6 mg/kg.
