What are aflotoxins?

Aflotoxin B1 Molecule

Aflatoxins are a class of mycotoxins being produced by certain mold types, which grow on food products under unfavorable conditions. The most common microorganisms producing aflatoxins are Aspergillus flavus, Aspergillus parasiticus, Aspergillus nomius, Aspergillus toxicarius, but there are several other species. Aflatoxins have been named after Aspergillus flavus. We know about 20 naturally occuring aflatoxins.

AZURA HPLC system for sensitive aflatoxin determination

With post-column photochemical derivatization and fluorescence detection

AZURA HPLC Aflotoxin System

The AZURA® Aflatoxin analysis system is specially designed to determine Aflatoxin B1, B2, G1, and G2 in food and feed products such as peanuts, corn and cottonseed. It utilizes efficient post-column photochemical derivatization to improve fluorescence sensitivity for aflatoxins B1 and G1 drastically.
