Abstract

This inventio discloses a method for determining major sweetening agents in an edible essence and flavor by HPLC-MS / MS. The method comprises the steps of preparing a matrix solvent, preparing a seriesof standard working solutions, preparing a sample solution, performing HPLC-MS / MS analysis, building a standard work curve, and performing sample result calculation. According to the method, curves are prepared and corrected by the matrix solvent for the first time; and an HPLC-MS / MS chromatograph is used for simultaneously determining nine kinds of major sweetening agents such as xylitol, acesulfame potassium, saccharin sodium, sodium cyclamate, sucralose, aspartame, neohesperidin, neotame and stevioside in edible essence. The method has the advantages that the proper matrix solvent is prepared, and is used for preparing a standard work curve; the influence caused by matrix effects on the quantification of target materials in the mass spectrometry ionization process is eliminated; the contents of the major sweetening agents in the edible essence can be simultaneously detected; the result is accurate; the interference is little; the sensitivity is high; and the repeatability is high,and the like.

Description

technical field [0001] The invention belongs to the technical field of detection of physical and chemical indicators of food additives, and in particular relates to a method for measuring main sweeteners in food flavors and fragrances by using HPLC-MS / MS. Background technique [0002] Flavors and spices are often used in the processing of food and related products. As the society pays attention to food safety issues, relevant government departments have established reasonable and effective supervision and management and safety evaluation laws and regulations to regulate the production of flavors, spices and related additives. production and use. Sweeteners are an important class of food additives used to improve the taste and flavor of food. Among them, non-sugar sweeteners have become substitutes for sucrose due to their advantages of high sweetness, low calorie, and not participating in metabolic processes. widely used in industry. In recent years, with the improvement o...
