EN 20436 DON Detection in Barley Malt
The European Standard EN 20436 outlines a robust method for detecting deoxynivalenol (DON), also known as vomitoxin, in barley malt. This standard is critical for ensuring food and feed safety, especially in the context of global grain trade.
Deoxynivalenol is a mycotoxin produced by fungi that can contaminate crops like wheat, barley, and maize under favorable conditions. When present at high levels, DON can cause significant health issues in humans and animals, including gastrointestinal disorders, reduced feed intake, and immune suppression.
The standard provides clear guidelines for sample preparation, instrumental analysis using gas chromatography coupled with tandem mass spectrometry (GC-MS/MS), and the calculation of DON concentration. The focus on this method ensures accurate quantification and traceability in barley malt, supporting regulatory compliance and ensuring consumer safety.
Compliance with EN 20436 is not only a legal requirement but also an essential step for quality management teams to ensure product integrity and customer satisfaction. R&D engineers can leverage this standard to innovate safer food products, while procurement officers can use it to source uncontaminated barley malt from reliable suppliers.
The method's precision and reliability are achieved through rigorous validation steps, which include linearity, accuracy, repeatability, and recovery tests. These steps ensure that the results obtained are both accurate and reproducible across different laboratories.
Given the potential health risks associated with DON contamination, it is essential to have a standard like EN 20436 in place. This ensures that barley malt producers and suppliers can maintain high-quality standards and comply with international food safety regulations.
| Parameter | Description |
|---|---|
| Linearity | The standard defines a linear range for DON detection from 1 to 50 ppb (parts per billion). |
| Accuracy | A recovery test ensures that the method recovers DON within ±10% of the spiked concentration. |
| Repeatability | The standard specifies a repeatability limit of 5% relative standard deviation (RSD). |
| Detection Limit | The detection limit for DON in barley malt is set at 1 ppb. |
The detection and quantification of DON are crucial steps in ensuring the safety of barley malt products. By adhering to EN 20436, laboratories can provide accurate and reliable results that meet regulatory requirements and customer expectations.
