The safety of the environment is closely related to food safety. With the rapid development of the world economy, environmental protection and management have been neglected, and environmental pollution can lead to food safety issues, thereby affecting human life safety. Compared with traditional environmental and food detection methods, the biggest characteristic of rapid detection technology is its fast detection speed, no high requirements for detection equipment and environment, and can directly achieve detection work in the production environment. Therefore, it plays an important role in the current environmental and food safety detection work

1. Rapid detection technology for environmental and food safety

1.1 Immunoassay

Immunoassay is an analysis of targets that need to be detected through specific binding reactions between antigens and antibodies, combined with immunoamplification technology.

. Due to the specificity of antigen antibodies, this method is often used in the detection process. Currently, methods that can be applied to rapid food detection include immunochromatography and immunomagnetic bead separation [1]

1.2 Chemical method

Chemical method refers to the process of detecting different chemical properties of different detection substances.

. Because different foods have different properties in different environments, and the impact of the environment on food can be demonstrated through certain methods, different chemical reactions of different foods will be used for detection during the detection process. For example, the commonly used redox reactions, synthesis and decomposition reactions in the detection process are all designed with certain environments and conditions to allow food to undergo chemical reactions in a fixed environment, and analyzed by observing their changes [2]

1.3 Biosensor Method

The biosensor method was invented by research and technical personnel in the United States. It mainly utilizes new material nanotechnology and applies it to the work of biosensors, using high accuracy and precision to achieve research on related issues. It plays an important role in the research of foodborne pathogens such as Salmonella.

. The relevant staff used grazing angle deposition technology to establish a thin film method and created an array of heterostructured silicon and gold nanorods. When Salmonella combines with molecules in organic dyes, the organic molecules will produce relevant reactions, which can determine the problem of Salmonella in food [3]. In the research process of this technology, in order to identify the detection results more easily, the relevant staff also carried out a series of reactions between the antibodies and Salmonella. That is to say, when the biosensor detects the presence of Salmonella in the detected substance, the biosensor will generate a strong fluorescent color, which can directly determine whether there are related pathogenic bacteria in the food with the naked eye. Due to its simple operation and low cost, this method has become increasingly widely used in current detection processes. Biosensors can not only detect problems with Salmonella, but also detect other substances by changing the type of antibody in the biosensor

1.4 Molecular biology method

Molecular biology method refers to the testing of the nucleic acid of pathogenic bacteria in food to determine the overall detection results.

. With the continuous progress and development of bioinformatics and molecular related technologies in China, more and more technicians are now choosing to test the nucleic acid of pathogenic bacteria. Because the overall cost of this method is low and it detects the nucleic acid of the pathogen itself, it has high accuracy. Therefore, more and more detection methods have been created based on this technology, among which polymerase chain reaction is the simplest and most accurate detection method. Therefore, this method has more and more application environments

1.5 Instrument analysis method

Due to the high precision and accuracy required for environmental and food safety testing, the entire testing process is required. If only manual sampling, testing, and comparison of the environment and food are relied on, the entire work will be relatively cumbersome, and the testing results will be affected by personal issues of the testing technicians.

. Therefore, in the current work process, more and more excellent detection instruments have been used, such as infrared spectrometers, laser Raman spectrometers, etc. For example, in the process of detecting the content of melamine in infant milk powder, a laser Raman spectrometer can be used to analyze the astigmatism generated by compound molecules in milk powder samples after being illuminated. By analyzing the range of incident light energy and the vibration frequency of the compound, the content of melamine in milk powder can be determined. Adopting this method not only reduces the cost of detection, but also has a very high accuracy. Therefore, more and more research departments are using instrumental analysis to alleviate the work pressure of technical staff and improve the efficiency of the entire detection and research work
