Is e422 vegan?

E422 is the European additive code for glycerol, which is also commonly known as glycerin. It is a colorless, odorless, sweet-tasting liquid used primarily as a humectant, thickener, sweetener, and preservative in food products. Manufacturers frequently add E422 to baked goods, confectionery, dried fruit, marshmallows, liqueurs, and dietary bars to retain moisture and improve texture.

Glycerol is obtained by splitting fats and oils into fatty acids and glycerin, often as a byproduct of soap or biodiesel manufacturing, though it can also be synthesized chemically from petroleum. The starting fats can come from plant sources, such as palm, soybean, or coconut oils, or from animal sources, such as beef tallow or pork fat.

E422 is classified as possibly vegan because ingredient lists rarely state whether the additive was derived from plant or animal fats. Unless the packaging explicitly specifies vegetable glycerin or vegetable E422, a certified vegan label or direct confirmation from the product manufacturer is needed to establish whether it comes from an animal or plant source.
