Abstract

The invention provides a method for detecting advanced glycation end-products (AGEs) in an aquatic product by using liquid chromatography-tandem mass spectrometry. The method comprises the following steps of: 1, extracting AGEs; 2, making a standard curve: drawing the standard curve by taking the concentration value of a standard substance as the abscissa and taking the standard substance area*(internal standard substance concentration/internal standard substance area) as the ordinate to obtain an equation; and 3, subjecting the treated sample to HPLC-MS/MS detection in a detection mode of MRMto obtain the AGEs peak area in the sample, and acquiring the AGEs concentration in the sample. The invention aims to establish the liquid chromatography-tandem mass spectrometry method, which can detect three AGEs (carboxymethyl lysine (CML), carboxyethyl lysine (CEL) and methyl glyoxal hydroimidazolone MG-H1) at one time and has the advantages of good separation degree, good linear relationship, wide linear range and the like.

Description

technical field [0001] The invention belongs to the field of detection of food harmful substances, in particular to a method for detecting advanced glycation end products in aquatic products. Background technique [0002] Advanced Glycation End-products (Advanced Glycation End-products, AGEs) are produced under non-enzymatic conditions by a series of reactions between the free amino groups of macromolecular substances such as proteins, lipids or nucleic acids, and the aldehyde groups of reducing sugars. stable compound. Medical research results show that AGEs are closely related to the occurrence of many human diseases, and dietary intake is an important source of AGEs in the body. Due to the difficult handling of food samples and the variety and complex structure of AGEs, there is a lack of general and effective methods for the detection of AGEs in food. At present, the methods for measuring AGEs at home and abroad are divided into instrumental method and immunochemical m...
