Aflatoxin is very harmful and has a wide range. In order to prevent the occurrence of aflatoxin poisoning and maintain human health, more than 70 countries and regions in the world have limited the amount of aflatoxin in food. Requirements. The following are the inspection and quarantine requirements for aflatoxins in food in some countries and regions:
1 The relevant laws of the US federal government stipulate that the aflatoxin content (the total amount of B1+B2+G1+G2) in human consumption food and dairy feed should not exceed 20ug/kg, and the content of M1 in human consumption milk should not exceed 0.5ug. /kg, the content of other animal feeds shall not exceed 300ug/kg;
2 The EU Regulation No. 1525/98, which was implemented by the European Union on January 1, 1999, stipulates that the content of aflatoxin B1 in the food directly supplied to humans and the components constituting the food shall not exceed 2 ug/kg, Aspergillus flavus The total amount of toxins B1, B2, G1, G2 shall not exceed 4ug/kg;
3 Japan stipulates that the content of aflatoxin B1 in food should not exceed 10ug/kg;
4 The allowable amount of aflatoxin B1 in Chinese food (GB2761-81) shall not exceed 20μg/kg in corn, peanut kernel and peanut oil, and 20μg/kg in corn and peanut kernel products (converted according to raw materials), rice, Other edible oils should not exceed 10μg/kg, and other foods, beans, and fermented foods should not exceed 5μg/kg. It should not be detected in infant milk substitute foods. Other foods can be tested according to the above standards; aflatoxin in cow's milk and its products. The M1 limited hygiene standard (GB9676-88) stipulates that the aflatoxin M1 in milk and its products shall not exceed 0.5 μg/kg.
At present, methods for determining aflatoxin in foods include thin layer chromatography, liquid chromatography, radioimmunoassay, enzyme-linked immunosorbent assay, immunochromatography, microcolumn screening, gold standard test paper, and the like. China's current national standard GB/T 5009.22-1996 specifies the determination method of aflatoxin B1 in food, GB/T 5009.23-1996 specifies the determination method of aflatoxin B1, B2, G1, G2 in food, GB/ T 5009.24-1996 specifies methods for the determination of aflatoxins M1 and B1 in foods. In addition, the Ministry of Health issued the “Measures for the Prevention of Aflatoxin Contaminated Food Hygiene†in November 1990.
The main measures to prevent aflatoxin from harming human health are to prevent food from being contaminated by aflatoxin and to minimize the possibility of human consumption of aflatoxin along with food. Therefore, it is necessary to strengthen the anti-mold and detoxification work of food in daily life. Reduce the moisture in the food, reduce the storage temperature and oxygen concentration of the food, ensure the drying and ventilation of the food storage warehouse, make the Aspergillus flavus difficult to grow; for the food contaminated with aflatoxin, panning, adsorption (vegetable oil), cooking, grinding Grinding (food), chemical methods (food and animal feed) and other methods to detoxify.
In addition, relevant standards in Europe and the United States should be stricter than China's national standard, and beware of setting up technical trade measures abroad, which in turn will affect the export of China's agricultural products.
Based on the leading fluorescence quantitative FPOCT technology platform, Shanghai Festo Biotechnology is the first to introduce aflatoxin fluorescence quantitative rapid detection system, which contains aflatoxin fluorescence quantitative rapid detector and aflatoxin fluorescence quantitative test strip, only need 8 minutes can quickly and accurately determine aflatoxins in grain, oil, grain, food, feed, Chinese herbal medicines, etc. The sample preparation is simple (only 7min), easy to operate, only one step of loading, no standard, no need The standard curve is accurate and reliable, and it is highly consistent with the test results of the national standard HPLC method (has been verified by the authority of the Grain Bureau). It provides a new technical means for the detection of aflatoxin and is gradually replacing the colloidal gold test paper. Article and enzyme-linked immunoassay kit, suitable for all kinds of raw material storage and storage, grain and oil processing enterprises, feed processing enterprises, aquaculture enterprises, pharmaceutical and government related regulatory departments, currently in Wudeli, Yihai Kerry, Uni-President Group, Guangming The feed group, and other large grain, oil and feed processing enterprises and multi-site grain depots, food and drug supervision and other government departments use.
