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
In recent years, the rapid development of genetic technology has led to the emergence of genetically modified foods. Up to now, there are still great controversies about the safety of genetically modified foods, but from a health perspective, it is necessary to strengthen the management and testing of genetically modified foods before a conclusion is reached on the safety of genetically modified foods. Chemiluminescence immunoassay has the advantages of strong specificity, high sensitivity, accuracy, simple operation and rapidity, which is in line with the current requirements for rapid and accurate detection of food quality and safety.
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
