Frequently asked

FAQ

Is E471 always non-vegan?

E471 refers to mono- and diglycerides of fatty acids, including glycerol monostearate. It is a 'check label' ingredient because the fatty acids can be sourced from either plants (like soy or palm) or animals. Many large-scale manufacturers now use plant sources, but it's not guaranteed without certification.

Is the glycerol monostearate in ice cream vegan?

It depends on the manufacturer. Many commercial ice creams use plant-derived E471, but unless the product is marked as vegan, there is a chance it could be animal-derived. Dairy-free ice creams are much more likely to use a vegan source.
