Mono- and di- glycerides and the Vegetarian Diet

Mono and diglycerides, also known as E471, are emulsifiers used to blend ingredients that typically do not mix well, such as oil and water. These compounds are formed by combining glycerol with fatty acids, which can be sourced from either plants or animals. Due to their potential animal origin, they may not be suitable for strict vegetarians unless specified as plant-based.
