This additive has several functions. However, it is mainly used as an emulsifier. It is used, for example, in the manufacture of bakery products to make the crumb softer, prevent bubbles from forming and give the products more volume. As with E471, various studies carried out on mice suggest that the consumption of this additive (and more generally, the consumption of emulsifiers) could lead to an increase in the permeability of the intestinal barrier and thus favour chronic inflammatory diseases of the intestine, increased adiposity (metabolic syndrome), and the development of diabetes. These additives could also disturb the balance of the intestinal flora, promoting autoimmune reactions. The chronic intestinal inflammation caused by these emulsifiers could finally promote the development of colon cancer.
