Top-15 allergen-free by design
We exclude peanut, tree nuts, milk, egg, wheat, soy, fish, shellfish, sesame, mustard, celery, lupin, sulfites, gluten, and animal proteins from the recipe, the line, and the supply chain.
Food Allergy
Safer food for the 1 in 13 children with a food allergy.
Food allergies affect more than 30 million Americans. Sentinel Biosystems is rebuilding food manufacturing so allergic families can finally trust what's on the label — and on the plate.
Why It Matters
Food allergy is a public-health crisis hiding in plain sight
Most processed food was never designed with allergens in mind. The result: avoidable ER visits, isolated lunch tables, and families who plan every outing around an EpiPen.
AI-driven manufacturing
Computer vision, traceability, and automated cleaning protocols keep every batch consistent and verifiable — not just labeled safe.
Built with allergy families
Lucian's Food was started by a family that lived the diagnosis. Every product is co-designed with the parents, kids, and clinicians who depend on it.
The Science
What's actually happening during a food allergy reaction
A food allergy is an IgE-mediated immune response to a specific food protein. On first exposure the body produces IgE antibodies; on re-exposure those antibodies trigger mast cells to release histamine and other mediators within minutes — causing hives, swelling, vomiting, wheezing, and in severe cases anaphylaxis.
Cross-reactivity makes things harder: someone allergic to peanut may also react to lupin, and someone allergic to birch pollen may react to apple, hazelnut, or carrot (pollen-food syndrome). Cross-contact during manufacturing is the other invisible risk — a "may contain" warning can mean anything from rigorous testing to none at all.
That's why Sentinel was built. Allergen-safe manufacturing isn't a marketing claim, it's a process discipline: dedicated lines, validated cleaning, supplier control, and verification at every step. Browse our allergen library for plain-language guides to each of the top 14 allergens, hidden ingredient names, and cross-reactivity clusters.
