Aflatoxin M1 in whole milk-powder reference materials

Area of Science:

• Food Safety
• Analytical Chemistry
• Reference Materials

Background:

• Aflatoxin M1 is a significant mycotoxin contaminant in milk and dairy products.
• Accurate quantification of aflatoxin M1 is crucial for ensuring food safety and regulatory compliance.
• The need for reliable reference materials for mycotoxin analysis in food matrices.

Purpose of the Study:

• To develop and certify full cream milk powder reference materials for aflatoxin M1.
• To provide certified reference materials for the validation of analytical methods for aflatoxin M1 in milk powder.
• To support accurate and consistent testing of aflatoxin M1 levels in dairy products.

Main Methods:

• Preparation of homogeneous full cream milk powder matrices.
• Certification of aflatoxin M1 content using validated analytical techniques.
• Characterization of reference materials within the Community Bureau of Reference Programme.

Main Results:

• Three reference materials (RM's 282, 284, 285) were successfully developed and certified.
• Certified aflatoxin M1 concentrations: <0.05 µg/kg (RM 282), 0.31 ± 0.06 µg/kg (RM 284), and 0.76 ± 0.05 µg/kg (RM 285).
• These materials provide traceable and reliable standards for aflatoxin M1 determination.

Conclusions:

• The developed reference materials are suitable for the accurate determination of aflatoxin M1 in full cream milk powder.
• These certified reference materials enhance the reliability of mycotoxin testing in the food industry.
• The availability of these RMs supports regulatory monitoring and quality control of dairy products.
