Aflatoxin (AFT) is a class of chemically similar compounds, all derivatives of dihydrofuran coumarin. Aflatoxin is a secondary metabolite produced primarily by Aspergillus flavus, a. parasiticus, with the highest incidence of aflatoxin in food and feed in hot and humid regions.
They are found in soil, animals and plants, and various kinds of nuts. Especially, they are easy to pollute peanuts, corn, rice, soybeans, wheat and other grain and oil products. They are the most toxic and harmful to human health.
In 1993, aflatoxin was classified as a Class 1 carcinogen by the World Health Organization (WHO) Cancer Research Institute. It is a highly toxic and highly toxic substance. The harm of aflatoxin is that it damages human and animal liver tissues. The effect can lead to liver cancer and even death in severe cases. Aflatoxin B1 is the most common in naturally polluted foods, and its toxicity and carcinogenicity are also the strongest. B1
is the most dangerous carcinogen and is often detected in corn, peanuts, cotton seeds, and some dried fruits. They produce fluorescence under ultraviolet light and are classified into two major classes, B and G, and their derivatives, depending on the color of the fluorescent light. AFT has found more than 20 kinds. AFT mainly pollutes grain and oil foods, animal and plant foods, etc.; such as peanuts, corn, rice, wheat, beans, nuts, meat, milk and dairy products, aquatic products, etc., all have aflatoxin contamination.Aflatoxin M1
is mainly left in dairy products and is extremely threatened for human health.
