Why
The patty uses soy protein concentrate, coconut and sunflower oil, and yeast-fermented heme (soy leghemoglobin) for the meaty flavour. There are no animal ingredients. Impossible Foods did carry out rat feeding trials on heme for US regulatory approval, which some vegans object to on principle even though the product is animal-free.
What to check on the label
- The ingredient list on your own pack — Impossible Burger recipes differ by country and change over time
- Milk, whey, casein, lactose, egg, honey, gelatin, carmine (E120) and shellac (E904) in the list
- "May contain milk" is an allergen cross-contamination note, not an ingredient — most vegans still buy it

Questions people ask
Is Impossible Burger certified vegan?
Certification is separate from the recipe. Many products with no animal ingredients carry no vegan mark because the maker will not rule out shared production lines. Check the pack for a registered vegan trademark, and treat the ingredient list as the primary evidence.
Does the answer change between countries?
Often, yes. The same brand name can use different fats, emulsifiers, colours or whey depending on the plant that made it, so always read the local label rather than an answer written for another market.
