All E number (15)
Agar-agar
✓ VeganAgar-agar is a natural vegetable gelatin extracted from red algae (Rhodophyta). 100% plant-based.
Beeswax
✗ Not VeganBeeswax is a biological wax secreted by worker honeybees from eight wax-secreting abdominal glands to construct the hexagonal honeycomb cells of their hive. Harvesting beeswax deprives bee colonies of their architectural habitat and food storage infrastructure, classifying it as strictly non-vegan.
Carmine
✗ Not VeganCarmine is a vibrant red dye extracted from crushed female cochineal insects (Dactylopius coccus). Thousands of insects are killed to produce small amounts of dye.
Carrageenan (E407)
✓ VeganCarrageenan is a family of natural linear sulfated polysaccharides extracted from red edible seaweeds (Rhodophyta). 100% plant/marine-algae derived.
Curcumin (E100)
✓ VeganCurcumin (E100) is the principal active yellow polyphenol extracted directly from the rhizomes of the turmeric plant (Curcuma longa). 100% natural vegan colorant.
Glycerine
⚠ CheckGlycerine (glycerol / E422) is a simple triol compound produced during the saponification or hydrolysis of triglycerides. Commercially, it can be manufactured from plant oils (soy, palm, coconut, or rapeseed) or recovered as a byproduct of rendering animal carcass tallow. Unless specified as 'vegetable glycerine' or certified vegan, source verification is required.
Guar Gum (E412)
✓ VeganGuar gum is extracted from the ground endosperm of the guar bean (Cyamopsis tetragonoloba). 100% plant-based thickening and stabilizing agent.
L-Cysteine
⚠ CheckL-Cysteine (E920/E921) is a semi-essential amino acid used as an industrial dough conditioner to relax gluten networks. Historically and commercially, the majority of global L-cysteine is extracted through acid hydrolysis of duck and poultry feathers or hog hair from slaughterhouses. Although modern microbial fermentation (bacterial biosynthesis) and synthetic routes exist, food ingredient labels almost never disclose the raw biological source without third-party vegan certification.
Lanolin
✗ Not VeganLanolin is a waxy substance secreted by the sebaceous glands of wool-bearing sheep. It is washed from sheep wool after shearing.
Lecithin
⚠ CheckLecithin (E322) is a generic term for a mixture of amphiphilic phospholipids and triglycerides. Over 95% of commercial food-grade lecithin is extracted mechanically and enzymatically from plant seeds, specifically soybeans, sunflower seeds, and rapeseed (canola). While lecithin was originally discovered in egg yolks (from the Greek lekithos), egg-derived lecithin is significantly more expensive and mandatory allergen labeling laws require it to be explicitly labeled as 'egg lecithin'.
Mono- and Diglycerides
⚠ CheckE471 emulsifiers can be synthesized from plant oils (soy, palm, sunflower) or animal fats (tallow, lard). Unless specified as vegetable-derived, source is ambiguous.
Pectin
✓ VeganPectin (E440) is a structural heteropolysaccharide naturally present in the primary cell walls of terrestrial plants. Commercially, it is extracted exclusively from citrus peels (lemons, limes, oranges) and apple pomace byproducts of fruit juice processing. It is 100% plant-derived and inherently vegan.
Red 40 (Allura Red AC / E129) is a synthetic azo dye manufactured from petroleum distillates and coal tar. It contains NO animal ingredients and is NOT made from crushed insects (which is Carmine / E120).
Shellac
✗ Not VeganShellac is a resin secreted by the female lac insect (Kerria lacca) onto trees in India and Thailand. The harvesting process results in the death of many insects.
Xanthan Gum (E415)
✓ VeganXanthan gum is a natural polysaccharide produced through the fermentation of glucose or sucrose by the bacterium Xanthomonas campestris. 100% vegan.
Understanding E number in Plant-Based Diets
Biochemical Origins & Production
Ingredients in the E number category can stem from plant crops, microbial fermentation, mineral synthesis, or animal byproducts. In modern industrial food processing, identical chemical compounds are frequently produced via both botanical and animal extraction routes.
When an ingredient has dual-source origin (such as glycerin, mono- and diglycerides, or stearic acid), vegan certification or direct manufacturer confirmation is necessary to ensure 100% plant or synthetic origin.
Label Reading & Ingredient Scrutiny
Food labeling regulations in major jurisdictions (including US FDA 21 CFR and EU Regulation 1169/2011) do not require manufacturers to disclose whether processing aids or multi-source carriers contain animal byproducts.
Always look for explicit "Suitable for Vegans" or "Certified Plant-Based" seals on packaged food products containing items flagged as Check Required.
