Direct peanut terms
Peanut, groundnut, earthnut, arachis oil, peanut flour, peanut protein, peanut butter, and mixed-nut ingredients are the clearest matches in the ingredient panel.

Peanut-Free Ingredient Checker App
Peanut-free shopping is more than looking for the word peanut. IngrediCheck helps families scan packaged foods against saved peanut-free rules, review peanut ingredients, snack-category risk, precautionary statements, shared-equipment clues, and household-specific allergy rules before a product goes into the cart.
Quick answer
A peanut-free ingredient checker should flag peanut, groundnut, peanut flour, protein, butter, and oil while separating direct ingredients from voluntary cross-contact statements. IngrediCheck supports label review for the saved profile, but it cannot certify a snack peanut-free or replace allergist and school guidance.
What It Catches
- Obvious peanut terms such as peanuts, peanut flour, peanut protein, peanut butter, peanut oil, and groundnut language.
- Snack and bakery labels where shared equipment, may-contain wording, or brand-specific manufacturing notes deserve closer review.
- Household-specific conflicts when peanut, tree nut, school-safe, or broader allergy rules need to stay separate.
Workflow
- 1.Scan the product and review direct peanut hits before checking broader snack or bakery risk clues.
- 2.Read precautionary statements separately from required allergen labeling so the risk signal stays clear.
- 3.Use the related peanut and allergy guides when brand policies, cross-contact risk, or school rules need a slower decision.

What the scan should help you review
Snack and bakery context
Chocolate, bakery items, ice cream, granola, candy, sauces, and bulk foods often deserve closer review because handling and shared lines may matter beyond the recipe.
Precautionary statements
May contain, shared equipment, and facility statements should stay visible and distinct from direct ingredients. Apply the household's clinician-approved rule rather than a universal risk score.
Decision boundary
IngrediCheck can match declared peanut terms and precautionary wording to a saved profile. It cannot verify a facility, detect undeclared contamination, certify school-safe status, or decide whether refined peanut oil is acceptable. Follow medical guidance and confirm uncertain manufacturing practices directly.

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.
proteinIngredient profile
Gluten
Gluten is the protein network that gives wheat-based dough elasticity, chew, and structure. It matters to label readers because avoiding gluten is not just about bread; it is about derivatives, cross-contact, and reformulation drift across packaged foods.
thickenerIngredient profile
Xanthan gum
Xanthan gum is a fermentation-derived thickener that shows up in gluten-free baking, sauces, dressings, and frozen desserts. It is often the ingredient that gives wheat-free products enough structure to hold together.

FAQ
Common questions
Can IngrediCheck prove a food is peanut-free?
No. IngrediCheck can flag peanut-related terms and label clues, but manufacturer controls, cross-contact policies, and medical risk decisions still require human review and clinician guidance.
Which peanut-free labels still need manual review?
May-contain statements, shared-equipment language, bakery and snack labels, imported products, reformulated foods, and brand policies can all deserve a slower check.
Can peanut-free and tree-nut-free rules stay separate?
Yes. Peanut and tree nut rules can differ by household, school policy, and allergy history, so IngrediCheck works best when each shopper's saved rules stay specific.
