How to detect Aspergillus flavus?

Abstract: Aspergillus flavus is the main substance for the production of aflatoxin in peanuts and rice, and aflatoxin is harmful to the human body. Therefore, in order to ensure food safety, it is necessary to detect Aspergillus flavus in food production and processing. To be considered, the application of the aflatoxin meter can determine if food is infected with Aspergillus flavus in a relatively short period of time, which has a very important role in ensuring food security.

Aflatoxin analyzer

Aflatoxins are mainly secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus, including more than 20 kinds of aflatoxins B1, B2, M1, and M2. Among them, aflatoxin B1 is the most common in naturally contaminated foods, with the highest toxicity and carcinogenicity. Aspergillus flavus is widely found in soil and most likes to “live” in carbohydrate-rich seeds such as grains, oil crops and nuts, among which the most vulnerable crops are corn, peanuts, walnuts and cottonseed, followed by rice. , wheat and beans. Therefore, for these foods, it is particularly necessary to do a good job of detection of Aspergillus flavus, and the aflatoxin analyzer is a professional instrument for the determination of aflatoxin, the use of the instrument can make the detection of Aspergillus flavus is not to worry about Less, but also more efficient and accurate.
In China, the State Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) stipulates that aflatoxin B1 is one of the most inspected items for most foods. According to GB 2761-2005, the limit values ​​of aflatoxin B1 in corn, peanut and its products, vegetable oils, rice, other foodstuffs, and infant formulas are 20, 10, 10, 5, and 5 μg/kg, respectively. Therefore, in order to meet the needs of rapid and accurate detection in different industries or groups of people, Topsun Yunnong has continued to innovate in this area, improved the detection method for aflatoxin B1, and finally successfully launched the aflatoxin analyzer. Sensitive detection of Aspergillus flavus has also been recognized and welcomed by the industry, further promoting the popularization and application of aflatoxin analyzers.
