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.
