A portable food allergen detection device was unveiled at CES 2026, designed to identify selected allergens and gluten in prepared meals within minutes. Developed by French startup Allergen Alert, the handheld system uses immunoassay-based technology to provide on-site screening outside laboratory settings. The device aims to support individuals with food allergies and intolerances by offering rapid, real-time information about potential allergen exposure in everyday dining environments.
At the Consumer Electronics Show (CES) 2026 held in Las Vegas, Nevada, January 6–9, 2026, a French biotechnology startup named Allergen Alert showcased a portable food allergen detection device designed to identify specific allergens and gluten directly in prepared meals. The prototype, referred to as a “mini lab,” is intended to provide results within minutes using a handheld platform.1
Food allergies and intolerances pose a documented public health concern. In the United States, approximately 9 percent of the population has one or more food allergies, and around 1 percent live with celiac disease, an autoimmune condition triggered by gluten. Reactions can range from mild symptoms to severe anaphylaxis, particularly when exposure occurs outside controlled home environments.2
Traditional approaches to managing allergies, such as reading labels or asking food preparers about ingredients are imperfect, especially in complex meals where cross-contact during preparation may not be visible or fully disclosed. Laboratory testing for allergens typically requires specialized analytical equipment and trained personnel.
A portable tool aims to supplement existing strategies by providing immediate, on-the-spot detection of targeted proteins in food samples.2
The Allergen Alert device is a battery-powered, compact instrument roughly the size of a small speaker or thick paperback book. Users place a small portion of food into a single-use pouch, which is then inserted into the mini lab. Upon activation, the device performs an automated analysis of the sample, with results displayed on its screen within minutes.1
Based on immunoassay technology, the system miniaturizes laboratory procedures such as sample preparation, protein extraction, and detection into a single integrated test. Immunoassays use antibodies with high specificity for targeted proteins, enabling detection of allergen-related molecules in a food sample.
This method is similar in principle to handheld gluten sensors that have been validated in peer-reviewed studies for detection above regulatory thresholds (e.g., detecting gluten at or above 20 parts per million).1
Although the prototype claims lab-level performance, comprehensive, independent validation data (for example, analytical sensitivity and specificity across diverse food matrices) has not yet been published in scientific journals or regulatory evaluations. Such performance metrics are critical for interpreting results and understanding limitations, particularly in heterogeneous food samples where allergen distribution may vary.
Allergen Alert originated as a spin-out from bioMérieux, a global leader in in-vitro diagnostics with longstanding experience in clinical microbiology and food safety technologies.
The company has engaged allergists and food safety experts in its development process. Initially, the device will test for a limited number of targets (including gluten and milk), with plans to expand detection to additional major allergens such as peanuts, tree nuts, soy, eggs, and shellfish over the next few years.
Product availability is planned for later in 2026, with pre-orders anticipated toward the end of the year. The business model includes selling the core device alongside disposable test pouches, often through subscription plans.
Portable consumer allergen detectors are not entirely new. Devices like the Nima sensor have been available for gluten and peanut testing, using antibody-based assays to indicate the presence or absence of target proteins at defined thresholds. Peer-reviewed evaluations have shown that such devices can reliably detect gluten at levels at or above regulatory limits with a low rate of false positives but variable performance depending on food type.3
However, neither existing handheld sensors nor this newly presented device replace formal laboratory analysis or clinical diagnosis. Instead, they are tools that may contribute additional informational support for individuals managing food allergies in real-world settings. Interpretation of results should be made alongside clinical guidance and an understanding of inherent limitations in sampling and detection.
