95% of restaurants in the Netherlands still track allergens manually, leading to costly mistakes. Setting up automatic allergen generation from your recipes eliminates errors and saves hours of administrative work every week. Here's how to build a system that updates allergen information instantly whenever you modify a recipe.
Why automatic allergen registration matters
Since 2014, as a restaurant owner you're legally required to provide allergen information to guests who ask for it. This applies to all 14 EU-mandated allergens.
⚠️ Heads up:
Incorrect allergen information puts you at liability risk. A guest who gets sick from an undisclosed allergen can hold you responsible.
The 14 mandatory allergens
You need to be able to trace these allergens in every dish:
- Gluten (wheat, rye, barley, oats, spelt, kamut)
- Crustaceans (shrimp, lobster, crab)
- Eggs (also in mayonnaise, pasta, baked goods)
- Fish (also in Worcestershire sauce, anchovies)
- Peanuts (also peanut oil)
- Soy (also in many Asian sauces)
- Milk (including lactose, butter, cheese)
- Tree nuts (almond, hazelnut, walnut, cashew, etc.)
- Celery (also celery salt, bouillon cubes)
- Mustard (also mustard seed in spices)
- Sesame (also in rolls, tahini)
- Sulfites (preservative in wine, dried fruit)
- Lupin (in some gluten-free products)
- Mollusks (mussels, squid, snails)
How automatic allergen registration works
The principle is straightforward: each ingredient gets its allergens assigned. Build a recipe, and all allergens from the ingredients are automatically collected.
💡 Example: Caesar Salad
Ingredients with their allergens:
- Romaine lettuce: no allergens
- Parmesan cheese: milk
- Anchovy fillets: fish
- Garlic: no allergens
- Mayonnaise: eggs
- Croutons: gluten
Automatic result: Contains gluten, eggs, fish, milk
Hidden allergens to watch out for
Many allergens hide in compound ingredients. This is something most kitchen managers discover too late - after they've already served incorrect information to guests:
- Bouillon cubes: often contain celery, soy, gluten
- Worcestershire sauce: contains fish (anchovies)
- Wine: contains sulfites (preservative)
- Asian sauces: often contain soy, fish, sesame
- Spice blends: can contain mustard, celery
- Bread and rolls: often have sesame on the crust
⚠️ Heads up:
Always check ingredient lists on packaging. Suppliers can change recipes without warning you.
Preventing cross-contamination
Automatic registration only helps with intentional allergens in your recipe. Cross-contamination needs separate handling:
- Separate cutting boards for fish, meat, vegetables
- Clean knives when switching between ingredients
- Don't share frying oil between fish and other products
- Nut-free zone in the kitchen for severe nut allergies
Digital vs. manual registration
Many restaurants still work with Excel spreadsheets or handwritten cards. The downsides:
- Error-prone: forget one ingredient, and your allergen info is wrong
- Time-consuming: every recipe change means you have to look everything up again
- Not up-to-date: supplier changes recipe, you don't know about it
Digital systems automatically link allergens to ingredients. Change a recipe, and the allergen info updates instantly.
💡 Example: Recipe Change
You replace regular mayonnaise with vegan mayo in your Caesar salad:
- Old allergen list: gluten, eggs, fish, milk
- New allergen list: gluten, fish, milk
The system automatically removes eggs from the list.
Practical tips for your team
Make sure your kitchen team knows how the system works:
- New ingredients: always check and enter allergens
- Supplier changes: verify allergens are the same
- Seasonal menu: new dishes = new allergen check
- Guest service: train staff on where to find allergen info
A good digital system makes this process 10x faster and more reliable than manual lists.
How do you set up automatic allergen registration? (step by step)
Create a complete ingredient list
Write down all ingredients you use, including sauces, spices, and additives. Check the packaging of each product and note which of the 14 allergens it contains.
Link allergens to each ingredient
Assign the correct allergens to each ingredient. Pay special attention to compound products like bouillon cubes, sauces, and spice blends—these often contain hidden allergens.
Test the system with existing recipes
Check whether the automatically generated allergen lists match what you determined manually. Update ingredients if you're missing allergens or assigned them incorrectly.
✨ Pro tip
Set up allergen tracking for your 7 most popular dishes within the next 48 hours. Once those are automated, you've eliminated 75% of potential allergen mistakes during peak service.

Frequently asked questions
Do I need to register cross-contamination in my system too?
No, you register cross-contamination separately. The system only shows intentional allergens from your recipe. For cross-contamination, you create separate procedures in your kitchen.
What if a supplier changes their recipe?
Regularly check ingredient lists on packaging. If in doubt, call your supplier directly. Update your ingredient database immediately if allergens are added or removed.
How often should I review my allergen registration?
Check all ingredients at least once per quarter, and always immediately with new suppliers or seasonal products. Make it part of your HACCP routine.
What if a guest asks about traces of allergens?
Traces aren't legally required to be disclosed, but it's smart for severe allergies. Be honest about your kitchen processes and possible cross-contamination risks.
