    Area of Science:

    • Food Science
    • Analytical Chemistry
    • Toxicology

    Background:

    • Aflatoxin M1 is a significant milk contaminant with potential health risks.
    • Accurate and rapid detection methods for aflatoxin M1 are crucial for food safety.
    • Existing methods can be time-consuming or costly.

    Purpose of the Study:

    • To develop a rapid and cost-effective screening method for aflatoxin M1 in milk.
    • To validate the performance of the developed minicolumn chromatography assay.

    Main Methods:

    • Development of a minicolumn chromatography technique.
    • Packing the minicolumn with Florisil, anhydrous sodium sulfate, and neutral alumina.
    • Visual detection of a blue fluorescent band indicating aflatoxin M1 presence.
