Food safety issues have not only seriously affected the health of the people's diet, but also hindered the export trade of my country's agricultural products and food, and undermined the international reputation of my country's food industry. Only by strengthening basic food safety research, especially rapid testing research, can we adapt to the development under the new international situation. How to quickly and effectively do a good job of testing, we have to bring up our powerful chemiluminescence immunoassay to see through which aspects it plays a role in food safety testing.
Detection of microorganisms in food
The inspection of microorganisms in food is mainly to inspect general pollution and pathogenic bacteria. Escherichia coli O157 H7 is an important food pathogen. The enhanced luminol peroxidase luminescence system can quickly detect E. coli O157:H7. The method is simple and fast. The minimum detection concentration of each bacteria is in the range of 104105CFU/L, and the recovery rate is between 90% and 120%.
Detection of biotoxins in food
Biotoxin is a general term for a large class of biologically active substances, including animal toxins, plant toxins and microbial toxins. Biotoxins have posed a serious threat to food safety and human health. For example, the chemiluminescence enzyme immunoassay method for detecting aflatoxin M1 in milk uses horseradish peroxidase to catalyze luminol to emit light.
Detection of pesticide residues in food
Pesticide residues in food can cause chemical food poisoning, and low-concentration residues are also potentially harmful to the human body. At present, the most researched pesticide residue detection technologies are mainly in vivo detection methods, chemical detection methods, enzyme inhibition methods and instrumental analysis methods. modified products
After recognizing the major changes brought to us by chemiluminescence reagents, Desheng has independently developed and produced chemiluminescence reagents since 10 years ago, including luminol, isoluminol, and acridinium ester and acridinium ester derivatives. product. These products are not only recognized by many companies in China, but are also well received even if they are exported overseas. Low-key life, high-profile work. What's more, a good product in the eyes of the public always speaks with strength.
Roche is a pharmaceutical and diagnostics company that produces a wide range of products, including reagents for laboratory use. Reagents are substances or compounds used in chemical analysis or other laboratory procedures to detect, produce, or measure other substances. Roche Diagnostics, a division of Roche, is known for manufacturing diagnostic solutions, including a variety of reagents for clinical chemistry, immunoassays, molecular diagnostics, and more. The specific reagents produced by Roche can vary widely depending on the application and the diagnostic platform.

Luminol has become one of the most widely used chemiluminescent reagents due to its advantages of high quantum yield, easy synthesis, and good water solubility. Its development process is the same as the arduous process of human beings. From the beginning, there is not much understanding, to the current glow and fever, it can only be summarized in one sentence: gold always shines. In the future, there may be more uses we don't know to benefit our lives. We only need to learn more about it to discover its unlimited potential as soon as possible. Application in the analysis of inorganic substances Using inorganic ions to enhance or inhibit the chemiluminescence of the luminol system, these metal ions can be measured. It is worth pointing out that some metal ions have higher catalytic activity than metal ions after being combined with complexing agents. For example, using the luminol-H2O2-silver phenanthroline system, the detection limit of silver ions can reach 2.7 10-g/L3. The use of sensitizers can improve the sensitivity of detection. The sensitization effect of triphenylmethane derivatives on the luminol luminescence system. It was found that Coomassie Brilliant Blue G250 had the best sensitization effect on the luminol-H2O2-Cu2+ system. A reverse flow injection technique was used to establish a measurement of Cu2+. The new method has a detection limit of 15. The use of the local concentration effect of surfactants to achieve micelle sensitization has been increasingly used in luminescence analysis. For example, the reversed micellar system FIA method is used to measure V4+, the detection limit is Luminol chemiluminescence analysis has been widely used in various fields, and new methods and new technologies are constantly emerging, especially the combination with FIA, HPLC and other technologies, which overcomes the shortcomings of poor selectivity in luminescence analysis and makes the analysis more flexible. Emblem and accuracy. Because of Rumi's stable performance and low price, practical application research and analysis will have broader application prospects.
