| Category | Common Products Containing Peanuts | Hidden Peanut-Derived Ingredients |
|---|---|---|
| Processed Foods | Granola bars, protein bars, cereals, snack foods | Hydrolyzed vegetable protein (HVP), peanut flour, peanut oil |
| Baked Goods & Snacks | Cookies, cakes, pastries, nut butters, energy bars | Nut paste blends, peanut flavoring, artificial nut extracts |
| Sauces & Condiments | Peanut oil in dressings, satay sauce, spicy sauces | Peanut oil (on US packaged foods it must be labeled as peanut unless highly refined; restaurant and unlabeled foods are the real risk) |
| Asian & African Cuisine | Thai, Chinese, Indian, African dishes (satay, peanut soup) | Ground peanut powder, peanut-based seasonings |
| Dairy Alternatives | Peanut-based non-dairy alternatives (peanut butter milk) | Peanut-based emulsifiers, peanut protein isolates |
| Chocolate & Confectionery | Chocolate bars, nougat, peanut butter fillings, pralines | Peanut butter solids, peanut-derived stabilizers |
| Protein & Health Supplements | Peanut protein powders, meal replacements, energy drinks | Hydrolyzed peanut protein, peanut flour in protein blends |
Key Insights
- Peanuts are commonly hidden in processed foods like granola bars, cereals, and snack items, listed as peanut flour or as hydrolyzed peanut protein (US law requires hydrolyzed proteins to name their source, so “hydrolyzed vegetable protein” alone should not hide peanut on a compliant label).
- Baked goods (cookies, cakes, energy bars) may contain peanut flavoring, nut paste blends, or artificial nut extracts.
- Peanut oil is frequently used in salad dressings, sauces, and Asian/Indian/African dishes. On US packaged foods, any peanut oil that is not highly refined must be declared as peanut; restaurant, imported and unlabeled foods are the real risk.
- Non-dairy products and protein supplements may use peanut-based emulsifiers or peanut protein isolates.
- Chocolate bars, nougat, pralines, and candy fillings often contain peanut butter solids or peanut-derived stabilizers.
Identifying Hidden Peanut Sources
| Label Term | Common Products Containing This | Risk Level for Peanut Allergy |
|---|---|---|
| Peanut Flour | Baked goods, cereals, protein bars | High |
| Peanut Oil | Dressings, sauces, frying oils | High — only highly refined peanut oil is exempt and generally tolerated; cold-pressed, expeller-pressed and gourmet oils are not |
| Hydrolyzed Vegetable Protein (HVP) | Processed foods, soups, snack foods | High |
| Ground Peanut Powder | Seasonings, spice blends, powdered sauces | High |
| Artificial Nut Flavoring | Confectionery, chocolates, flavored drinks | High |
| Nut Paste Blends | Nut butter alternatives, spreads | High |
| Peanut Protein Isolate | Protein shakes, meal replacements | High |
| Peanut Butter Solids | Chocolates, energy bars, peanut-flavored foods | High |
| Vegetable Oil (unspecified) | Chips, fast food items, margarine substitutes | Moderate |
| Hydrolyzed Plant Protein | Soups, processed meats, canned goods | High |
| Cold-Pressed, Expeller-Pressed, or Extruded Peanut Oil | Fried foods, restaurant-prepared meals | High |
| Peanut-Based Emulsifiers | Creamy products, non-dairy items | High |
| Lecithin (unspecified source) | Candy, chocolates, processed foods | Low (if sourced from soy, sunflower, or egg, but unclear source is risky) |
Key Insights
- High-risk peanut-derived ingredients include Peanut Flour, Hydrolyzed Vegetable Protein (HVP), Ground Peanut Powder, and Peanut Protein Isolate
- Peanut Oil may be a risk depending on processing—highly refined peanut oil is generally considered safe, while cold-pressed or expeller-pressed oils may still contain allergens.
- Hidden peanut sources in processed foods include Artificial Nut Flavoring, Nut Paste Blends, and Peanut Butter Solids.
- On US packaged foods, peanut-derived lecithin, flavorings and hydrolyzed proteins must declare peanut, and selling unrefined peanut oil as plain “vegetable oil” would be misbranding. Unspecified vegetable oils, lecithin and hydrolyzed plant protein are a real risk mainly in restaurant, imported and unlabeled foods — ask, or avoid them when the source is unknown.
