China's self-developed aflatoxin rapid tester came out
After ten years of research, it broke through. China's "agricultural aflatoxin affinity microsphere rapid measurement technology and rapid tester" with completely independent intellectual property rights has been published in the Institute of Oil Crops of the Chinese Academy of Agricultural Sciences.
Experts' observation and evaluation of the research results showed that after the operator started the new lightweight and dexterous speedometer, three different agricultural product samples were measured on site, and each sample was measured for only 16 minutes. And the test results can be displayed on the same machine, and the direct readings refresh the international fastest detection record of 1 hour, and the detection sensitivity is high and the accuracy is high, reaching 0.1цg/kg (three billion).
Experts attending the appraisal meeting believe that this research not only fills the domestic gap, but also is superior to similar testing technologies at home and abroad, reaching the international advanced level.
Aflatoxin is a type of biotoxin that has been found to be the strongest toxin of contaminated agricultural products, and is also a strong carcinogen. Because aflatoxin can occur in any part of crop growth, harvesting, drying, processing and storage, it can easily contaminate agricultural products such as peanuts, corn, rice, soybeans, edible vegetable oil, cakes and feeds, and thus directly enter the food chain. It causes chain pollution of starchy foods, animal foods, meat, eggs, milk, etc. At present, aflatoxins are found even in processed products such as oilseeds, dried fruits, condiments, fermented products, Chinese herbal medicines, and wines that are produced from agricultural products.
It is understood that since aflatoxin pollution has become a serious threat to human health, the detection of aflatoxin content in agricultural products has become a mandatory trade technical measure. Because China's original aflatoxin detection technology can not meet the needs of domestic and international agricultural product safety consumption and trade detection, especially the lack of rapid, simple and quantitative detection technology suitable for on-site and port inspection, China has suffered a huge agricultural trade economy. loss.
Researcher Li Peiwu, the project's host, said that there are many methods for detecting aflatoxins internationally and domestically, but most of them require fixed large-scale precision instruments, which are complicated to operate, take a long time, and have high detection costs. The rapid measurement technology and equipment developed can carry out random field measurement of aflatoxin content on more than 50 kinds of agricultural and side-processed products, even including soy sauce, vinegar and alcohol, which has the advantage of "all-round".
Experts believe that this achievement provides key technical support for ensuring the safety of China's bulk agricultural products and edible oil consumption, promoting the production and processing of high-quality agricultural products and exporting foreign exchange, increasing farmers' income, and promoting the implementation of the “Non-pollution Food Action Planâ€. At present, the research results have applied for two invention patent protections to the National Patent Office, and foreign manufacturers and research and development institutions have proposed cooperation intentions.
