Frequently asked
FAQ
Is all lecithin vegan?
No. While most lecithin in food is derived from soy, sunflower, or rapeseed (all vegan), it can also be derived from egg yolks, which is not vegan. If a label just says 'lecithin,' it's usually soy, but it's best to check if you want to be certain.
Why is soy lecithin used in chocolate?
It acts as an emulsifier to reduce the viscosity of the chocolate mixture. This makes the chocolate flow better during production and results in a smoother final product with a longer shelf life.
Should people with a soy allergy avoid soy lecithin?
Most people with soy allergies can safely consume soy lecithin because it contains very small amounts of soy protein. However, individuals with a severe or highly sensitive soy allergy are often advised to avoid it.
