Common Animal-Derived Food Additives

Some food additives are always animal-derived, some are usually plant-based, and a third group can come from either source depending on manufacturing. Knowing which category an additive falls into saves time at the supermarket.

Below is a reference organised by function: colours, gelling agents, glazing agents, emulsifiers, and flavour enhancers.

Additives that are always animal-derived

These additives cannot be vegan regardless of brand or country. If any appear on a label, by E-number or name, the product is not vegan.

Colours

E120 (carmine / cochineal) is a red pigment from cochineal insects. Related names include cochineal extract, carminic acid, and natural red 4. Plant-based red alternatives include beetroot red (E162), anthocyanins (E163), and paprika extract (E160c).

Gelling agents

E441 (gelatin) is collagen from animal bones and skin. Related names include gelatin, hydrolysed collagen, and collagen peptides. Vegan gelling alternatives: agar (E406), pectin (E440), carrageenan (E407), gellan gum (E418).

Glazing agents

E901 (beeswax) comes from honey bees. E904 (shellac) comes from lac insects. US labels may say "confectioner's glaze" (shellac) or "carnauba wax" (E903, plant-based and vegan).

Anti-caking agents

E542 (edible bone phosphate) is calcium phosphate from animal bones.

E120, E441, E901, E904, and E542 are never vegan. No variation in production method changes their animal origin.

Source-dependent additives

These additives are permitted from both plant and animal sources. The E-number or name alone does not tell you which.

Emulsifiers

Flavour enhancers

E631 (disodium inosinate) can be from meat/fish or fermentation. E635 (disodium 5'-ribonucleotides) combines E631 and E627 and carries the same source uncertainty.

Dough conditioners

E920 (L-cysteine) may be synthetic, fermented, or from feathers/hair. E922 (potassium persulfate) is an oxidising agent that is generally synthetic and vegan.

Usually vegan additives (often confused)

These are sometimes mistaken for animal-derived additives but are typically plant, mineral, or synthetic. E153 (vegetable carbon) comes from charred vegetables, not bone char. E407 (carrageenan) comes from seaweed. E410 (locust bean gum) comes from carob seeds. E903 (carnauba wax) comes from palm leaves and is vegan, unlike beeswax.

Shellac (E904) and carnauba wax (E903) are easy to confuse: one is insect-derived, the other is plant-derived.

Additives by product category

Additives vs ingredients on the label

Additives are a subset of ingredients: substances added for a technical function (colour, preservation, texture) rather than nutrition or flavour alone. On labels, they appear in the same ingredients list, often with their E-number in parentheses.

Regulatory systems classify them separately for approval purposes, but as a shopper you read them the same way. Our additives database covers individual E-numbers; our ingredients database covers common ingredient names.

Scanning a label for additives

Look first for E120, E441, E901, E904, E542. If any are present, the product is not vegan. Flag E471, E322 (unspecified), E631, and E920 for follow-up. Look up unfamiliar E-numbers in our E-Number Checker, and see our complete E-number guide for deeper reference. Vegan certification is the most reliable shortcut when source-dependent additives appear.

Preservatives and acids: usually safe

Most preservatives, acidity regulators, and mineral salts are vegan. E200–E252 (sorbates, benzoates, propionates), E260–E270 (acetic, citric, and lactic acids), E300–E341 (ascorbic acid, tocopherols, calcium phosphates, not E542 bone phosphate), and E500–E585 (sodium bicarbonate, calcium carbonate, ferrous gluconate) appear on nearly every processed food label and rarely cause problems for vegans.

Sweeteners and thickeners

Most artificial and natural sweeteners are vegan: aspartame (E951), sucralose (E955), stevia (E960), and sorbitol (E420) are synthetically produced or plant-derived. Thickeners like xanthan gum (E415), guar gum (E412), and locust bean gum (E410) come from fermentation or plants.

The main sweetener concern is not animal origin but processing context: some cane sugar in flavoured products may involve bone char, which is a separate issue from additive status.

Anti-caking and mineral additives

Most anti-caking agents and mineral salts are vegan. Silicon dioxide (E551), calcium silicate (E552), and magnesium carbonate (E504) are mineral-derived. The exception is E542 (bone phosphate), which comes from animal bones. Check for that specific code rather than avoiding all phosphates.

Regional differences in additive use

The same product category can use different additives by country. US breakfast cereals may fortify with lanolin-derived vitamin D3; EU versions of the same brand may use a different D source or omit fortification. Candy sold in the UK may list E-numbers while the US version lists the same substances by name.

Evaluate the package you are holding, not a screenshot from another country shared on social media.

Where additives concentrate

Minimally processed foods (plain rice, dried lentils, fresh produce, plain tofu) rarely contain additives. The additive problem concentrates in bread, confectionery, processed snacks, margarine, and ready meals. Shopping mostly from the perimeter of the supermarket reduces your exposure to uncertain E-numbers.

Certification as a shortcut

When a product carries the Vegan Society sunflower mark, V-Label, or Certified Vegan logo, the certifier has verified that source-dependent additives like E471 come from plant sources. This is the most reliable shortcut for additive-heavy products like supermarket bread and margarine. Uncertified products are not automatically non-vegan; they just require more homework.

Common mistakes

Confusing E903 (carnauba wax, vegan) with E904 (shellac, not vegan) is the classic mix-up. E153 (vegetable carbon) does not involve bone char. "No artificial colours" does not exclude carmine, because E120 is a natural colour. E-numbers can hide in products that otherwise look plant-based, and "free from artificial additives" does not mean vegan when natural animal additives exist.

Many E-numbers are everyday substances like vitamin C (E300) and baking soda (E500), not exotic chemicals. Additives increase with processing level, so plain oats may be fine while the flavoured instant version is not.
