The additive E551, present in thousands of references (2,600), promotes gluten intolerance. It is present, for example, in instant soups, baby cereal preparations or even powdered foods such as cocoa.

The National Research Institute for Agriculture, Food and the Environment (INRAE) warns of a new product, E551.
