Allergen Detection and Quantification

Comprehensive Allergen Detection and Quantification Services for Food Safety, Label Compliance, and Consumer Protection

Food allergens are a major public health concern, affecting an estimated 2–4% of adults and 5–8% of children worldwide. The inadvertent presence of undeclared allergenic ingredients—such as peanut, tree nuts, milk, egg, soy, wheat, fish, and crustacean shellfish—poses a serious risk to allergic consumers and can lead to life-threatening anaphylactic reactions. In response, regulatory authorities worldwide (including the U.S. FDA, the European Commission, and Codex Alimentarius) have established stringent labelling requirements and action levels for allergenic residues. The accurate, sensitive, and reliable detection of food allergens is therefore not merely a quality control measure but a legal and ethical imperative for food manufacturers, ingredient suppliers, and the hospitality industry. Our specialised detection platform offers a fully validated suite of analytical methods—including enzyme-linked immunosorbent assay (ELISA), lateral flow devices (LFD), and advanced liquid chromatography-tandem mass spectrometry (LC-MS/MS)—delivering unparalleled sensitivity, specificity, and matrix adaptability. Whether the client is a food producer, a contract testing laboratory, an export trader, or a regulatory authority, our service provides the precise, regulatory-ready data required to safeguard allergic consumers, maintain label accuracy, and ensure compliance with national and international allergen legislation.

Scientific and Regulatory Drivers for Allergen Analysis

Clients seeking allergen detection services are motivated by a range of critical compliance, safety, and trade imperatives. In food manufacturing and quality control, the primary need is to verify the absence of undeclared allergens in finished products, to monitor the effectiveness of cleaning procedures in shared production lines, and to confirm the identity and purity of raw ingredients. In label compliance and consumer protection, accurate allergen data are essential to meet the requirements of regulations such as the U.S. Food Allergen Labeling and Consumer Protection Act (FALCPA), the EU Food Information for Consumers Regulation (FIC), and the Codex General Standard for the Labelling of Prepackaged Foods. In risk assessment and incident investigation, rapid and robust analytical methods are required to trace the source of allergen contamination and to evaluate the effectiveness of allergen control plans. In research and product development, detailed allergen profiling supports the validation of new processing technologies, the development of hypoallergenic products, and the study of allergen stability and bioavailability. In regulatory submissions, validated analytical data are a prerequisite for the approval of new food ingredients, processing aids, and allergen-reduction technologies. Our service is architected to address these diverse needs with a flexible, ISO 17025‑accredited analytical framework that adapts to the specific allergen target, sample matrix (processed foods, raw ingredients, environmental swabs, rinsates), and the client’s regulatory or research context.

Integrated Analytical Pipeline for High-Fidelity Allergen Profiling

Our analytical platform is organised into three interconnected modules that collectively ensure reliable and reproducible allergen quantification. The Sample Preparation Module employs optimised extraction and cleanup protocols tailored to the specific matrix and allergen target, including buffer-based extraction with additives for protein stabilisation, immunoaffinity capture for specific allergens, and solvent-based extraction for lipid-rich matrices. We incorporate appropriate internal standards (e.g., stable isotope-labelled peptide standards for MS methods) to correct for extraction losses and matrix effects, achieving recoveries of 85–105% with relative standard deviations (RSD) < 5%. The Immunoassay Module offers a choice of primary screening platforms: sandwich ELISA using allergen-specific monoclonal antibodies (for major allergens including peanut, milk, egg, soy, wheat, and hazelnut) with LOQs as low as 0.1 ppm (mg/kg) in food matrices and inter-assay precision < 8% RSD, and lateral flow devices (LFD) for rapid qualitative or semi-quantitative screening with results available in 10–20 minutes, ideal for in-process control and environmental monitoring. The Confirmatory and Quantitation Module uses ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) with a C18 reversed-phase column (1.7 µm), employing a gradient mobile phase of water/acetonitrile with 0.1% formic acid, achieving baseline separation of multiple allergen-specific marker peptides (e.g., from peanut, milk, egg, soy, and gluten) within a run time of 15 minutes. Detection is performed by tandem mass spectrometry (MS/MS) in positive electrospray ionisation (ESI) mode with multiple reaction monitoring (MRM), providing LOQs as low as 0.5 ppm for most allergens in complex matrices, with inter-day precision < 6% RSD and accuracy of 90–110%. For the identification of unknown or unexpected allergens, we deploy high-resolution mass spectrometry (HRMS) on a Q-TOF instrument for untargeted protein profiling. The Data Validation Module includes system suitability tests (retention time, peak symmetry, signal-to-noise ratio), matrix-matched calibration to eliminate ion suppression, and regular participation in international proficiency testing schemes (e.g., FAPAS, LGC) to ensure ongoing accuracy. All methods are validated according to AOAC guidelines and EN 15633/15634 standards, and we provide full validation dossiers including specificity, linearity, accuracy, precision, LOD, LOQ, recovery, matrix effect, and measurement uncertainty.

Unmatched Sensitivity, Selectivity, and Matrix Versatility

Our platform routinely delivers performance that surpasses regulatory requirements and typical industry capabilities. For peanut detection, our ELISA method achieves LODs of 0.05 ppm in cookies and chocolate, while our LC-MS/MS method achieves LOQs of 0.5 ppm for the marker peptide. For milk allergen (β-lactoglobulin), we achieve LODs of 0.1 ppm in processed meat products. For gluten, our validated ELISA (R5 or G12 antibody) provides LOQs of 5 ppm (as gluten), well below the Codex threshold of 20 ppm for gluten-free labelling. The MRM transitions are highly specific, with no detectable interference from isobaric matrix components after our optimised cleanup. For complex matrices such as chocolate, spices, and bakery products, our optimised extraction protocols effectively remove co-extracted polyphenols, lipids, and polysaccharides, resulting in signal-to-noise ratios > 100:1 at the LOQ. We also offer multi-allergen screening for up to 15 major allergens in a single LC-MS/MS run, providing a comprehensive risk assessment for products with complex ingredient lists. Our automated sample handling and high-throughput capability allow processing of up to 100 samples per day for ELISA and 50 samples per day for LC-MS/MS, making our service ideal for routine quality control and large-scale monitoring programmes. This depth and breadth of analysis ensure that our clients receive not only compliance data but also a comprehensive understanding of their allergen risk profile.

Advanced Data Integration, Predictive Modeling, and Reporting

We understand that analytical data must inform risk management decisions. Our final reports are structured to deliver three levels of information: (i) a certificate of analysis (CoA) presenting the allergen concentration (with measurement uncertainty) and a clear pass/fail judgement against the client's specified action level or regulatory limit; (ii) a detailed analytical report containing raw data, calibration curves, quality control results, sample preparation details, and instrument parameters; and (iii) an interpretive summary that places the results in the context of the client's operations—for example, explaining the likely source of contamination, assessing the effectiveness of current cleaning procedures, or recommending targeted interventions. For clients with multiple time-points or locations, we perform statistical analysis (t-tests, ANOVA) and provide trend plots to visualise changes over time. We also offer predictive modeling of allergen risk based on processing parameters, using our internally developed algorithms. All raw data files (e.g., .raw, .csv, .dx) are supplied for full transparency and re-analysis.
