The development of aflatoxin rapid testing instrument, a leading agricultural product in the world

Introduction: the reporter recently learned from the Institute of oil crops, Chinese Academy of Agricultural Sciences that the aflatoxin rapid tester for agricultural products was successfully developed in Wuhan It can detect the strong carcinogens in agricultural products in 16 minutes, exceeding the detection record of the fastest one hour in the world This technology has passed the expert appraisal organized by the science and Technology Department of Hubei Province Experts believe that the detector has strong detection sensitivity and high accuracy, which not only fills the domestic blank, but also is superior to the similar detection technology at home and abroad, reaching the international advanced level Aflatoxin B1 (AFB1 for short) has been listed as a highly toxic substance in the world and strictly controlled As aflatoxin can occur in any link of crop growth, harvest, air drying, processing and storage, it is very easy to pollute agricultural products such as peanut, corn, rice, soybean, edible vegetable oil, cake and feed, and thus directly enter the food chain, causing the chain pollution of starch food, animal food and meat, eggs, milk, etc At present, the international detection of aflatoxin content in agricultural products has become a compulsory trade technical measure However, there was a lack of rapid, simple and quantitative aflatoxin detection technology in China Researcher Li Peiwu, the project host, said that there are many international and domestic methods to detect aflatoxin, but most of them need fixed large-scale precision instruments, which are complex in operation, time-consuming and high in detection cost After 10 years of painstaking research, several scientists of the Institute finally overcome this "difficult problem" At present, the research results have applied for two invention patents to the State Patent Office.
