Direct animal ingredients
Start with milk, egg, gelatin, honey, meat stocks, fish ingredients, shellac, and carmine. These are clearer label matches than source-dependent additives and should be shown separately.

Vegan Ingredient Checker
Is this ingredient list vegan? Paste the food label below to check for animal-derived ingredients and additives whose source needs confirmation. This free online tool uses vegan rules; no app download or account is needed.
Check a food ingredient list for vegan ingredients
Review the current package and confirm unresolved sources with the manufacturer. A checker result is not vegan certification or an allergy-safety guarantee.
The browser checker reviews the ingredient text you submit against vegan rules. For barcode scans, label photos and saved personal or family food notes, use the IngrediCheck app. Neither workflow verifies undisclosed sourcing or replaces vegan certification. Confirm any uncertain result with the manufacturer.
Checking vegetarian rules instead? Use the vegetarian ingredient checker, which treats dairy and eggs differently. For personal and family scanning, explore the IngrediCheck food scanner app.
What It Catches
- Obvious animal-derived ingredients such as dairy, egg, gelatin, honey, and fish-derived additives.
- Ambiguous names that may need brand confirmation, including lecithin, mono- and diglycerides, natural flavors, and vitamin carriers.
- Products where a vegan claim, allergen statement, or ingredient list deserves a second pass.
App scanning workflow
- 1.Scan the barcode or ingredient panel before adding the product to your cart.
- 2.Review the flagged ingredients against your vegan profile and tolerance for ambiguous additives.
- 3.Open the related guide or ingredient profile when the label needs source-specific confirmation.

What the scan should help you review
Source-dependent additives
Mono- and diglycerides, glycerin, enzymes, vitamin D3, natural flavors, stearates, and some emulsifiers can come from plant, animal, or synthetic sources. The label alone may not settle them.
Claims and certification
Plant-based, dairy-free, and vegetarian claims do not always answer a strict vegan question. Review the full ingredient panel, certification marks, and manufacturer guidance when sourcing matters.
Decision boundary
The browser tool reviews declared ingredients against vegan rules. It cannot verify undisclosed processing aids, shared equipment, supplier changes, or an additive's private sourcing. Use certification or manufacturer confirmation when the label stops short.

Ingredient profiles
emulsifierIngredient profile
Lecithin
Lecithin is a broad label term for phospholipid-rich emulsifiers used in chocolate, baked goods, dressings, infant foods, and supplements. The source can be soy, sunflower, egg, or less commonly animal tissue.
additiveIngredient profile
MSG
MSG is a flavor enhancer used in savory packaged foods such as soups, noodles, snacks, and seasoning systems. It matters because it remains legally accepted by mainstream regulators while still carrying unusually strong cultural baggage in clean-label and retailer discussions.
preservativeIngredient profile
Calcium propionate
Calcium propionate is a mold-inhibiting preservative commonly used in bread, buns, tortillas, and other packaged baked goods. It matters because it sits at the center of a real shelf-life tradeoff between softer bread products and simpler ingredient decks.

FAQ
Common questions
Can a scanner prove a product is vegan?
A scanner can flag ingredients that conflict with a vegan profile and surface ambiguous names, but brand sourcing and cross-contact policies can still require confirmation from the manufacturer.
What vegan ingredients are hardest to identify on labels?
Lecithin, natural flavors, mono- and diglycerides, vitamin D, confectioner's glaze, and enzyme language can require context because the same label term may have plant or animal origins.
Does IngrediCheck replace vegan certification?
No. Certification is still the strongest quick signal. IngrediCheck helps with first-pass label screening and deeper review when a product is not certified.
