foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents" drafted. This document replaces GB/T 23884-2009 "High-performance liquid chromatography for the determination of biogenic amines in animal-derived feeds", and Compared with GB/T 23884-2009, in addition to structural adjustment and editorial changes, the main technical changes are as follows. ---Added the determination of tryptamine, phenethylamine and octopamine; added shrimp meal, chicken meal, pork meal, blood meal, feather meal, fish pulp, squid Cream and silkworm chrysalis powder for 8 animal-derived feed ingredients; the detection limit of the method was revised and the quantification limit was increased (see Chapter 1,.2009 Chapter 1 of the edition); --- Modified the derivatizing agent, derivatizing conditions and derivatizing post-processing method (see 5.11, 8.2, 4.1, 7.1.2, 7.1.3 of the.2009 edition); --- Modified the chromatographic gradient elution procedure (see Table 1, Table 1 of the.2009 edition); --- Deleted "chemical names, molecular formulas and relative molecular masses of 6 biogenic amines" (see Appendix A of the.2009 edition); --- Revised the liquid chromatogram of biogenic amines (see Appendix A, Appendix B of the.2009 edition).

3 Terms and Definitions

There are no terms and definitions that need to be defined in this document.

4 Principles

The biogenic amines in the samples were extracted with perchloric acid solution, derivatized with dansyl chloride, determined by high performance liquid chromatography, and quantified by external standard method.

5 Reagents or materials

Unless otherwise specified, only analytical grade reagents were used. 5.1 Water. GB/T 6682, Class I. 5.2 Acetonitrile. chromatographically pure. 5.3 Acetone. 5.4 Ammonia. 5.5 Ammonium acetate. chromatographically pure. 5.6 Ammonium acetate solution (5mmol/L). Weigh 0.38g of ammonium acetate (5.5), dissolve in water, and dilute to 1L. 5.7 Perchloric acid extract (0.4mol/L). Accurately measure 32.3mL of perchloric acid, and dilute to 1L with water. 5.8 Sodium hydroxide solution (2mol/L). Accurately weigh 8g of sodium hydroxide and dilute to 100mL with water. 5.9 Saturated sodium bicarbonate solution. Add enough solid sodium bicarbonate to water until it can no longer dissolve. 5.10 Hydrochloric acid solution (0.1mol/L). Accurately measure 8.3mL of concentrated hydrochloric acid, and dilute to 1L with water. ......
