EN 20284 T-2 and HT-2 Residue Testing in Wheat Products
The presence of mycotoxins in wheat products can pose significant health risks to humans, animals, and livestock. EN 20284, a European standard for the determination of tricothecene mycotoxins (including T-2 toxin and HT-2 toxin) in foodstuffs and feedstuffs, is crucial for ensuring safety. This service ensures that wheat products meet stringent quality and regulatory standards.
T-2 toxin and HT-2 toxin are potent inhibitors of protein synthesis, particularly affecting the ribosomes of target organisms. These mycotoxins can cause a range of adverse effects including nausea, vomiting, diarrhea, and even death in extreme cases. The European Union (EU) has set maximum levels for these toxins to protect public health.
In wheat products, T-2 toxin and HT-2 toxin are often found due to the contamination of cereals with Fusarium species. These fungi thrive in warm, moist conditions, making them a common source of mycotoxin contamination in agricultural environments. The testing process involves several critical steps: sample collection, extraction, purification, quantification, and confirmation.
Sample preparation is meticulous; it requires the accurate removal of any foreign materials to ensure that only pure wheat samples are analyzed. Extraction methods typically involve the use of solvent-based techniques such as acetonitrile or methanol, followed by solid-phase extraction (SPE) for purification. The purified extracts undergo liquid chromatography with tandem mass spectrometry (LC-MS/MS), ensuring high sensitivity and specificity.
Accurate quantification is paramount; the standard method involves calibration curves generated from known concentrations of mycotoxins. A minimum detection limit of 0.5 μg/kg is achieved, which aligns with EU regulations for maximum levels in wheat products. Confirmation is made through confirmation tests that include reagent blank checks and spiked recovery studies.
Compliance with EN 20284 ensures product safety and protects against potential contamination issues. This service not only meets regulatory requirements but also enhances brand reputation by ensuring consistent quality across batches of wheat products. By adhering to these standards, we contribute significantly to the global food supply chain's integrity.
The testing process is highly regulated and involves a series of checks at each stage to ensure accuracy and precision. The use of LC-MS/MS provides results with exceptional reliability, making it an essential tool in maintaining the quality of wheat products.
