Scope

Scope: This document specifies the method for the determination of 4-hydroxy-hexenal (HHE) and 4-hydroxy-nonenal (HNE) in dried fish by liquid chromatography-tandem mass spectrometry (LC-MS/MS). This document is applicable to the determination of HHE and HNE in edible tissues of dried fish products such as mackerel, pomfret, cod, and swordfish. Main technical content: 3.1 Dried fish products are those made from fish raw materials that are either directly dried or dried after salting, pre-cooking, or seasoning under natural or artificial conditions. 4. Principle: After derivatization of HHE and HNE in the sample with 2,4-dinitrobenzohydrazide in hydrochloric acid solution, they are extracted with dichloromethane, purified using a silica gel solid phase extraction cartridge, and determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) with internal standard quantification. 5. Reagents and materials: Unless otherwise specified, all reagents used are analytical grade, and the water meets the requirements of Class I water specified in GB/T
