Testing of weight loss health foods

The testing methods for weight loss health foods cover multiple aspects to ensure the safety, compliance, and functionality of the products. Here are some of the main testing methods:

1. Nutritional component analysis

Protein, fat, and carbohydrates: The content of these basic nutrients in food can be determined by methods such as high-performance liquid chromatography (HPLC) and gas chromatography (GC).

Vitamins and minerals: The presence of trace nutrients in food can be detected by methods such as atomic absorption spectroscopy (AAS) and ultraviolet-visible spectroscopy (UV-Vis).

2. Functional component detection

Dietary fiber, alkaloids, and plant sterols: These ingredients are closely related to health and are usually quantitatively analyzed by chromatography (such as HPLC and GC).

Probiotics, enzymes: The content and activity of active substances can be detected by methods such as microbial culture and enzyme-linked immunosorbent assay (ELISA).

3. Detection of pollutants and harmful substances

Pesticide residues: The use of methods such as gas chromatography-mass spectrometry (GCMS) can detect pesticide residues such as organochlorine and organophosphorus that may be present in food.

Heavy metals: The content of heavy metals such as lead, mercury, cadmium, and arsenic in food can be determined by atomic fluorescence spectroscopy, atomic absorption spectroscopy, and other methods.

Additives and preservatives: Chromatography, mass spectrometry, and other methods can be used to detect whether food additives such as preservatives, pigments, and sweeteners used in food meet the prescribed standards.

IV. Detection of illegal additives

Liquid chromatography-mass spectrometry (LC-MS/MS): This is one of the main methods for detecting illegal additions of drugs. It has high sensitivity, high selectivity, and accuracy. It is suitable for detecting the illegal addition of a variety of chemical drugs such as caffeine, fenfluramine, and sibutramine.

Gas chromatography-mass spectrometry (GCMS): It is suitable for detecting highly volatile chemical drugs, such as furosemide and other illegal additives.

Enzyme-linked immunosorbent assay (ELISA): It can be used to quickly screen drug residues in a large number of samples. It is simple to operate and suitable for large-scale preliminary screening.

V. Other detection methods

Stability test: Evaluate the chemical stability of health foods during storage and transportation, including changes in color, odor, taste, etc.

Label and packaging material testing: ensure the accuracy of label information and the safety of packaging materials.

Allergy testing: test for allergic substances that may be contained in food, such as peanuts, milk, eggs, etc.

Radioactive material testing: test for radioactive substances in food to ensure that they meet safety standards.

Genetically modified ingredient testing: test for genetically modified ingredients that may be contained in food.

In summary, there are many testing methods for weight loss health foods, covering nutrients, functional ingredients, contaminants, harmful substances, illegal additives, and other aspects. These testing methods together constitute a complete system for quality control of weight loss health foods, providing a strong guarantee for the safety and compliance of products.
