Is it vegan? Additives & E-numbers E406
Is agar vegan?
Quick answer: Yes. Agar (E406) is a gelling agent made from red algae and is a popular vegan substitute for gelatin.
Also called: E406, agar-agar, kanten
Why it’s vegan
Agar, also called agar-agar or kanten, is extracted from red seaweeds. It sets firmly at room temperature and is used in jellies, desserts, vegan cheeses and confectionery. EFSA re-evaluated agar (E406) as a food additive in 2016.
As a rule of thumb, agar is much stronger than gelatin by weight, so recipes use far less; it must be boiled to dissolve and set.
