The demand for faster, more accurate, and scalable allergen detection has never been greater. Traditional methods like ELISA and PCR, while reliable, can be time-consuming and limited in scope. Emerging technologies are poised to transform the landscape of food allergen testing with greater precision diagnostics, real-time monitoring, and data-driven risk management.
AI-enhanced testing & non-destructive diagnostics are reshaping allergen detection through methods such as Hyperspectral imaging (HSI), Fourier Transform Infrared (FTIR) spectroscopy and Computer Vision (CV). These methods, when combined with machine learning, allow non-destructive, real-time allergen detection without altering food integrity. AI models can also predict allergenicity of new ingredients before they enter the supply chain, improving safety and formulation decisions.
With detection limits as low as 0.01 ng/mL, multiplexed immunoassays and mass spectrometry technology can simultaneously quantify specific proteins in foods that are responsible for allergic responses such as peanut (Ara h 3, Ara h 6), milk (Bos d 5), egg (Gal d 1, Gal d 2), and shellfish (Tropomyosin). The key benefits of this technology include high sensitivity and specificity, and scalability across all key allergens that feature in labelling regulations around the world. Mass spectrometry is also gaining traction for its ability to detect proteotypic peptides across complex food matrices, offering new levels of precision compared with existing methods.
ATP (Adenosine Triphosphate) meters, traditionally used for hygiene monitoring, are now being incorporated in cloud-based allergen control systems. Cloud-based platforms that integrate ATP readings with microbial and allergen data can provide visualised heat maps and trend rings across facility surfaces This can help manufacturers home in on real-time sanitation verification, inform automated sample scheduling and offer centralised dashboards for audits and compliance. These systems support predictive risk management and reduce the cost of rework and recalls.
As these technologies continue to mature, they will enable faster decision-making, greater consumer safety, improved regulatory compliance and more personalised allergy management for people living with food allergies.
