Understanding gums & thickeners
Thickeners are overwhelmingly plant, seaweed or microbial in origin: xanthan gum is fermented by bacteria, guar and locust bean gum come from seeds, pectin from fruit, and carrageenan and agar from seaweed.
The exception is gelatine (E441), which is boiled from the collagen of pig skin, cattle hide and bone, and which competes directly with the plant gums in gels, mousses and confectionery.
Gelatine is also used as a clarifying agent in juices, wines and beers, where it is filtered out and therefore may not appear in the ingredient list at all.
What to check on the package
- 1.
Gelatine must be declared in food, so a gum listed without it is almost certainly plant-based.
- 2.
Xanthan gum is occasionally grown on a dairy-derived medium; the finished gum is generally accepted as vegan.
- 3.
For drinks, ask about finings rather than reading the label — finings are processing aids.
- 4.
Agar-agar, pectin and carrageenan are reliable plant-based setting agents.
For drinks, Barnivore listings and 'suitable for vegans' statements on the bottle are more useful than the ingredient list, because finings are legally invisible.
From label to decision
What does the ingredient list actually tell you?
Check the complete formula first. Then separate ingredients with a clear origin from those needing manufacturer confirmation. Uncertainty is a reason to investigate, not a reason to invent an answer.
- 01
Read the exact formula
Include coatings, sauces and fillings. Use the variant and country on the package, not an old listing for another product.
- 02
Identify what is unresolved
Names such as glycerin or E471 may not state their source. An additive number alone does not settle vegan suitability.
- 03
Verify the missing evidence
Check current certification or ask the manufacturer about the named ingredient and any animal-derived processing aids.
Animal-derived
Whey · honey · gelatin
An intentionally added animal ingredient means the product is not vegan.
Source-dependent
Glycerin · E471 · some D3
Keep the answer unresolved until product-specific sourcing is confirmed.
Plant-derived ingredient
Oats · agar · sunflower oil
These ingredients can be vegan; still check everything else in the product.
A label-reading example
Illustrative chocolate label
Ingredients: cocoa mass, sugar, cocoa butter, sunflower lecithin.
May contain milk.
No animal ingredient is named in this illustrative formula. The milk warning concerns possible cross-contact, not an intentional ingredient. For allergy safety, follow an allergy plan. For processing-aid questions, seek product-specific evidence.
Read about lecithinCheck the evidence before choosing
Vegan ingredients, cruelty-free testing policies and environmental claims answer different questions. Check the exact product and its market, not just the brand name or a badge on the front of the pack.
Compare price per serving or use, the full ingredient list and any certification in the certifier’s own directory. Missing evidence means the claim is unconfirmed; it does not automatically mean the product fails.
- A practical example
- For a plant milk, compare protein and fortification alongside price per litre. For skincare, check ingredients and animal-testing policy separately.
- What to keep in mind
- Formulas, prices and certification can change. A ranking is a starting point for comparison, not a guarantee or an independent laboratory test.
When a label needs a closer look
A snack can look plant-based yet contain whey, honey or carmine. Check the exact flavour and pack sold in your country: another item from the same brand may have a different recipe.
If a scan has incomplete information, compare it with the label in your hand or analyse the ingredient text. An unclear source is a reason to ask the manufacturer, not proof that the ingredient is animal-derived.
- A practical example
- For a protein bar, look for milk proteins first, then check ambiguous additives and the source of any vitamin D3.
- What to keep in mind
- A vegan verdict is not an allergy clearance. Check allergen warnings and cross-contact information separately.
Understand what an impact estimate means
Environmental estimates compare a choice with an assumed alternative. The result depends on the ingredients, production method and comparison used; it is not a measurement of your individual supply chain.
Use the trend to understand repeated choices rather than treating a single total as precise. Reducing food waste and choosing meals you will keep making can matter more than chasing a perfect score.
- A practical example
- Compare a regular bean-based meal with the meat-based meal it replaces, while keeping portion sizes and food waste in mind.
- What to keep in mind
- Water, emissions and cost figures are estimates. They do not prove a particular product is carbon-neutral or universally more sustainable.
