Description

technical field

[0001] The invention relates to a test paper card for detecting aflatoxin B1 and its application, in particular to a colloidal gold test paper card for detecting aflatoxin B1, which is especially suitable for grains such as soybeans and corn and feed (raw materials, batch materials, etc.) , concentrate) detection of aflatoxin B1 residues in samples. Background technique

[0002] Aflatoxin (AF) is the strongest type of biological toxin found to pollute agricultural products so far, and it is also a strong carcinogen. It is a class of metabolites produced by various fungi such as Aspergillus flavus and A. parasiticus, a group of compounds with similar structures. It is easy to naturally exist in crops such as peanuts, cottonseed, corn, wheat and rice, and has strong toxicity and carcinogenicity. It is the strongest carcinogenic mutagen among chemical carcinogens, and its toxicity is 10 times stronger than potassium cyanide. times, its carcinogenicity is 75 ti...
