E478 is a food additive, also known as glycerol monocaprylate, used in the food industry as an emulsifier.
Emulsifiers help mix ingredients that don’t normally mix, such as water and oil.
E478 is commonly used to improve the texture and structure of food products such as margarine, cookies, pastries, dairy products, and others.
While E478 is generally considered safe for consumption, some individuals may be sensitive to certain emulsifiers and other food additives.
