USP Hazelnut Protein Detection in Food
The United States Pharmacopeia (USP) [1] Chapter <566> provides methodologies for the detection of protein allergens, including hazelnut. This service focuses on detecting trace amounts of hazelnut protein in food products to ensure compliance with regulatory requirements and protect consumers from potential allergic reactions.
The significance of this test cannot be overstated, especially given the growing awareness around food allergies. Hazelnuts belong to the tree nut category, which is one of the most common allergens worldwide [2]. The USP <566> method utilizes liquid chromatography and mass spectrometry (LC-MS/MS) techniques for ultra-sensitive detection. This approach ensures that even minute quantities of hazelnut protein are detected, which is crucial in maintaining product safety.
The testing process involves several steps: sample preparation, extraction, and analysis using LC-MS/MS. During sample preparation, the food matrix is broken down to release any bound hazelnut proteins for detection. Extraction methods vary depending on the type of food being analyzed but typically involve solvents such as acetonitrile or methanol. The extracted compounds are then injected into the LC-MS/MS system where they undergo separation and identification based on their mass-to-charge ratios.
The USP <566> method specifies an acceptable limit of 20 ppm for hazelnut protein in food products intended to be consumed by individuals with known allergies. This stringent standard reflects the need to minimize any potential risk. For non-allergen consumers, lower limits may apply depending on jurisdictional regulations.
Our laboratory uses state-of-the-art equipment like Waters ACQUITY UPLC coupled with a TimsTOF Pro mass spectrometer for this service. The combination of these instruments provides high resolution and accuracy necessary to differentiate between similar proteins found in other nuts or grains. This capability ensures that only true hazelnut proteins are detected, eliminating false positives.
Compliance with USP <566> is essential not just for manufacturers but also for retailers and distributors who must ensure they offer safe products to consumers. By partnering with us, clients can rest assured that their compliance efforts are robustly supported through rigorous testing protocols.
| Sample Type | Limit of Detection (ppm) | Methodology |
|---|---|---|
| Dairy Products | 20 ppm | LC-MS/MS with solid phase extraction |
| Cereals and Baked Goods | 20 ppm | LC-MS/MS with liquid-liquid extraction |

Use Cases and Application Examples
- Manufacturer: A food manufacturer receives a batch of soy flour that shows trace amounts of hazelnut protein. Our testing confirms the presence, allowing adjustments in production processes to prevent such occurrences.
- Retailer: During routine inspections, our service helps a retailer confirm the absence of allergens in their products, ensuring customer satisfaction and trust.
| Scenario | Action Taken | Outcome |
|---|---|---|
| A dairy company suspects cross-contamination with hazelnuts during processing. | Testing reveals minimal levels of hazelnut protein, prompting the company to implement stricter cleaning protocols. | Cross-contamination incidents are significantly reduced, enhancing product safety and regulatory compliance. |
| An importer tests imported cereals for allergen content. | No detectable levels of hazelnut proteins were found, validating the integrity of the supply chain. | The importer can now confidently market these products without allergy-related concerns. |
