Embodiment 1

[0075] Rapid detection of 221 illegally added ingredients in health care products claimed to have weight loss effects, including the following steps:

[0076] (1) Pretreatment of the object to be tested:

[0077] a The samples to be tested are the contents of tablets, granules, and capsules. Take the sample and grind it to a fine point, and accurately weigh 1 g of the mixed sample, accurate to 0.01 g, and put it in a 50 mL brown volumetric flask, add 20 mL of methanol aqueous solution (50:50 ), ultrasonicated for 10 min, cooled to room temperature, the volume ratio of methanol aqueous solution was 50:50 to the scale, and passed through a 0.22 μm organic filter membrane for instrument measurement;

[0078] b. The sample to be tested is a liquid. Accurately weigh an oral dose sample into a 50mL brown volumetric flask, add 20mL methanol aqueous solution with a volume ratio of 50:50, ultrasonicate for 10 minutes, cool to room temperature, and adjust the volume to the mark with a v...

Abstract

The invention relates to a method for rapidly detecting 221 illegally added components in health food. The method comprises the following steps: (1) pretreatment of a detected object; (2) preparing 221 reference substance single standard stock solutions, and preparing a mixed standard working solution and a plurality of standard series solutions according to the concentration gradient; (4) establishing chromatographic separation conditions and mass spectrum conditions; establishing a first-level spectrum library; and establishing a secondary high-resolution mass spectrum database. The method has the beneficial effects that the ultra-high performance liquid chromatography-quadrupole-time-of-flight high-resolution mass spectrometry is used for establishing a method for detecting 221 illegally added chemical components in the health food, and a high-resolution mass spectrometry database of corresponding illegally added chemical substances is established. And compared with corresponding characteristic fragment ions in a high-resolution mass spectrum database, qualitative and quantitative risk screening and determination can be carried out on 221 illegally added chemical substances for health food supervision sampling inspection and risk monitoring. The method can be used for accurately analyzing and detecting illegal added components of the health care product in a more targeted, faster and more effective manner, so that the component detection and analysis are faster. The method is simple in process, high in detection precision and sensitive in detection.

Description

technical field [0001] The invention belongs to the technical field of detection of illegal addition of health products, and develops a detection method for illegally added chemical components in food. Background technique [0002] Health food is composed of natural nutrients and special active substances. The biggest feature that distinguishes it from medicine is that it does not contain any pharmaceutical ingredients, has no therapeutic function, and cannot cause any harm or side effects to the human body. Article 2.1 of my country's GB16740-2014 "National Food Safety Standard for Health Food" defines health food as: food that claims to have specific health functions or supplements vitamins and minerals. Due to the special properties of health food, some businesses are motivated by interests and choose to add illegal drugs to health food to achieve the purpose of improving the functionality of their products. With the improvement of people's living standards in our countr...
