Frequently asked

FAQ

Is Wonder Bread vegan?

Most common varieties of Wonder Bread in the USA, including the classic white bread, are generally considered vegan as they do not list milk or eggs. However, they contain mono- and diglycerides whose source is not specified, so strict vegans may wish to avoid it.

What is L-cysteine in bread and is it vegan?

L-cysteine (E920) is an amino acid used as a dough conditioner. While it can be sourced synthetically or from plants, it has historically been derived from animal sources like duck feathers or pig bristles. Vegan-certified bread is the safest way to avoid animal-derived L-cysteine.

Are mono- and diglycerides in bread vegan?

Mono- and diglycerides (E471) are emulsifiers that keep bread soft. They can be derived from either animal fats or vegetable oils (like soy or palm). Since the source is rarely listed, these ingredients make bread a 'check label' item unless the product is certified vegan.
