EN 21477 Citrinin Detection in Red Yeast Feed
The European standard EN 21477 specifies the method for the determination of citrinin, a mycotoxin produced by certain fungi, particularly Tolypocladium inflatum, in red yeast feed. Citrinin contamination is a significant concern due to its toxic effects on animals and humans when consumed through contaminated food products or animal-derived foods like dairy or meat.
This standard employs liquid chromatography with tandem mass spectrometry (LC-MS/MS) for accurate quantification of citrinin in red yeast feed. This method ensures high sensitivity, specificity, and accuracy, making it the preferred choice for laboratories aiming to comply with international standards and regulatory requirements.
Red yeast is widely used in food production as a flavoring agent and natural dye. However, its use can lead to significant health risks if contaminated with citrinin. Proper testing not only ensures product safety but also protects consumers from potential toxicity effects such as liver damage and immunosuppression.
The detection process involves several steps: sample preparation, extraction, clean-up, and analysis by LC-MS/MS. The method is rigorous and stringent, ensuring that even trace amounts of citrinin are detected and quantified accurately. Laboratories adhering to this standard provide reliable results, which can be crucial for maintaining the integrity of food safety regulations.
Compliance with EN 21477 is essential for producers, distributors, and manufacturers who use red yeast in their products. It helps them stay ahead of regulatory changes and maintain a competitive edge by ensuring that their products meet or exceed international standards. By adhering to this standard, they not only protect public health but also enhance consumer trust.
The process described in EN 21477 is highly sensitive and specific, allowing for the detection of citrinin at very low levels. This ensures that even small amounts of contamination are identified early, providing ample time for corrective actions to be taken. Additionally, the standard's rigorous methodology helps laboratories achieve consistent results across different batches or samples.
Given the importance of this test, it is crucial for quality managers and compliance officers to understand its significance in maintaining product safety and regulatory compliance. R&D engineers can also benefit from this knowledge as they work on developing new products or improving existing ones. Procurement teams can leverage this expertise when selecting suppliers who use red yeast feed in their production processes.
