Proper soya allergen disclosure prevents legal issues and protects your customers from potentially dangerous reactions. Most restaurants overlook soya in common ingredients like soy sauce, tofu, and tempeh. Failing to identify these allergens correctly puts both your business and diners at risk.
Why take soya allergy seriously?
Soya allergies affect roughly 0.3-0.5% of people, with children being particularly vulnerable. Reactions range from minor skin irritation to severe respiratory distress. That's why accurate allergen disclosure isn't optional—it's legally mandated across all EU countries.
⚠️ Watch out:
Soya hides in far more products than most chefs realize. Bouillon cubes, ready-made sauces and vegetarian meat substitutes frequently contain soya too.
Recognize soya in all your ingredients
Soya appears in various forms throughout professional kitchens:
- Soy sauce (light and dark varieties)
- Tofu (soft, firm and smoked versions)
- Tempeh (fermented soybeans)
- Miso paste (for soups and marinades)
- Soya oil (refined version is usually safe, but mention it)
- Vegetarian meatballs (often contain soya protein)
- Teriyaki sauce (contains soy sauce as base)
- Bouillon cubes (many brands contain soya extract)
💡 Example:
You make teriyaki chicken with these ingredients:
- Chicken thigh: no allergens
- Teriyaki sauce: contains soy sauce = SOYA
- Sesame oil: contains sesame seeds = SESAME
- Rice: no allergens
This dish contains: soya and sesame seeds
Prevent cross-contamination
Using soya products means you need strict protocols to avoid cross-contamination:
- Use separate cutting boards for tofu and other ingredients
- Wash your hands after working with soy sauce
- Use different spoons for soya-containing and soya-free sauces
- Store soya products separately in the fridge
I've seen restaurants face a mistake that costs the average establishment EUR 200-400 per month—failing to prevent cross-contamination during busy service periods. One contaminated batch can ruin multiple dishes and create serious liability issues.
💡 Cross-contamination example:
You make two dishes side by side:
- Pad Thai with soy sauce (contains soya)
- Simple stir-fried vegetables without sauce
If you use the same spatula, the stir-fried vegetables now also contain soya traces.
Digital allergen registration
Paper-based allergen tracking becomes messy fast. Digital systems help you:
- Record which allergens are in each ingredient
- Automatically calculate which allergens appear in each dish
- Quickly search which dishes are soya-free
- Apply recipe changes directly to allergen information
⚠️ Watch out:
No app registers allergens automatically. You're still responsible for correctly entering allergen information per ingredient.
Practical tips for your menu
You don't need every allergen listed on your menu. But you must provide accurate information if guests ask:
- Use symbols: (S) for soya, (G) for gluten, etc.
- QR code: Link to online allergen information
- Separate allergen card: Overview per dish
- Verbal information: Train your staff to inform correctly
💡 Example menu mention:
Instead of listing all allergens per dish:
"Do you have questions about allergens in our dishes? Ask our staff or scan the QR code for complete information."
This is legally sufficient and keeps your menu clear.
How do you register soya correctly in your recipes?
Check all your ingredients
Go through your entire ingredient list and mark everything that contains soya. Don't forget ready-made products: bouillon cubes, marinades and vegetarian products often contain soya.
Register per ingredient
Note for each soya-containing ingredient that it contains the allergen 'soya'. If you use a digital system, you can set this per ingredient so it automatically applies to all recipes.
Check your recipes
Review each recipe and make sure all soya-containing dishes are correctly marked. Train your kitchen team to always check for hidden soya sources when creating new recipes.
✨ Pro tip
Check your 15 most-used bouillon cubes and ready-made sauces within the next 48 hours—many contain hidden soya that could trigger reactions. This quick audit prevents costly oversights during busy service periods.
Calculate this yourself?

Frequently asked questions
Do I also need to mention soya oil as an allergen?
Refined soya oil usually contains no soya proteins anymore and rarely causes allergic reactions. But to be safe, you can mention it anyway.
What if I'm not sure whether an ingredient contains soya?
Always check the label from your supplier or ask them directly. When in doubt, it's safer to mention soya than to leave it out.
Can I use 'may contain traces of soya'?
This statement is meant for unintended cross-contamination during production. If you deliberately use soya ingredients, you must simply state 'contains soya'.
How do I train my staff about soya allergens?
Make sure your staff knows which dishes contain soya and where soya is hidden. Create a simple list of commonly used soya products for the kitchen.
What happens if I forget to mention soya?
In case of an allergic reaction, you can be held liable. The food safety authority can impose fines for incorrect allergen information. Correct disclosure is therefore crucial.
Does fermented soya like tempeh still cause allergic reactions?
Yes, fermentation doesn't eliminate soya proteins that trigger allergies. Tempeh, miso, and fermented soy sauces all require the same allergen disclosure as regular tofu.
