Physical and chemical testing of food is an important method to ensure food quality and safety. It is of great significance to continuously improve the technical means of food physical and chemical testing to ensure food safety. Through the physical and chemical testing of food, not only can the nutritional components of food be analyzed, but also can check whether food contains harmful substances to human body, thus ensuring the quality and safety of food from the root. Physical and chemical testing of food is a way to strengthen food quality and safety control. Through physical and chemical testing of food, unqualified food can be screened out and safe food can flow into the market. The diversification of food types leads to the diversification of food quality problems. Therefore, scientific and effective food physical and chemical testing technology can not only ensure the safety of food quality, but also make the food industry healthy and safe development. Compared with precision instrument analysis, conventional physical and chemical testing methods are more dependent on the operation skills and daily experience of testing personnel, and there are a large number of test types, corresponding chemical reagents, instruments and equipment.

At present, the common physical and chemical testing methods in food include titration, colorimetry, distillation, spectrophotometry, etc. At present, the more common testing methods in food include GB 5009 series and food product standard Appendix method, etc.
