Automate, Validate, and Stay Audit-Ready even Against Hidden Allergens

Accurate menus are critical for guest safety and your business reputation. US laws including ADDE Act (SB-68), which mandates that major allergens must appear on menus in California by July 2026, and Food Allergen Labeling and Consumer Protection Act (FALCPA) requires major allergens—including derivatives—to be declared on packaged foods. These allergens include those present as both proteins and protein derivatives in foods.

• Proteins are naturally occurring molecules that can trigger allergic reactions in sensitive individuals e.g. Soybeans.
• Protein derivatives are processed forms of proteins, often used in sauces, flavorings, or sub-recipes e.g. Soy Sauce.

Protein derivatives are particularly tricky to track because they may be highly processed, appear in small amounts, or be hidden in composite ingredients and sauces.

Why Hidden Allergens are Tricky

Some allergens are obvious in your supply chain, such as peanut butter, but others can be difficult to detect without a digital system or proper allergen training—like sesame oil in tahini or anchovy paste in sauces. These “hidden allergens” often appear in sauces, dressings, marinades, pre-prepared ingredients, or sub-recipes.

• Derivatives such as whey, soy lecithin, or anchovy paste are often overlooked.
• Cross-contact during prep or frying can introduce unexpected allergens.
• Different versions of the same ingredient can have different allergens

Even trace amounts can trigger severe allergic reactions, making it essential to track all hidden allergens throughout your supply chain. Automated systems help flag potential risks instantly, keeping recipes and menus accurate.

Spotting Hidden Allergens in Practice

Recipe and menu management systems can make sure you have an automated, systematic process for identifying and disclosing allergens before they reach your guests, but your team should also be trained to identify where allergens are usually found as a final check—an extra layer of safety for your consumers.

Allergen	Common Derivatives & Sources	Hidden in Foodservice Items
Milk	Casein, Whey, Lactose, Butterfat	Sauces, soups, baked goods, coffee foams
Eggs	Albumin, Lysozyme, Lecithin (egg)	Mayonnaise, dressings, pastries, fried foods
Wheat	Flour, Semolina, Spelt, Modified Starch	Soups, sauces, batter, spice blends, beer
Soybeans	Soy Sauce, Miso, Tofu, HVP, Soy Lecithin	Asian sauces, baked goods, chocolate
Fish	Anchovies, Fish Sauce, Fish Stock	Worcestershire sauce, Caesar dressing, relishes
Crustacean Shellfish	Shrimp Paste, Seafood Stock	Shared fryers, soups, bisques, sushi
Tree Nuts	Nut Flours, Marzipan, Pesto, Nut Oils*	Baked goods, pesto, granola, desserts
Peanuts	Peanut Oil**, Peanut Flour, Peanut Protein Hydrolysate	Satay, Pad Thai, curries, baked goods
Sesame	Tahini, Sesame Oil, Sesame Seeds	Buns, bagels, hummus, marinades

*Highly refined nut oils may be exempt if no protein remains. **Peanut oil requires declaration unless verified as highly refined.

Implementing these systems and training your team ensures your recipes and menus are accurate, helping prevent allergic incidents and strengthen consumer trust.

Practical Steps to Reduce Risk

Automated tools are powerful, but combining them with trained staff ensures the highest level of allergen safety. Consider these steps:

• Audit recipes automatically, including sub-recipes and sauces.
• Validate supplier data instantly via the portal—ingredients can change without notice.
• Link sub-ingredients to parent allergens in your system to prevent errors.
• Train staff to respond to automated alerts while focusing on service.

While hidden allergens can be difficult for food service operators to manage, digital systems allow you to make sure your data is updated in real-time from your vendor to guest.

Accurate, automated allergen management protects your guests, strengthens compliance, and builds trust in your brand.
