Silver (Ag) is a food additive (E174) approved by the European Commission to be used for the external coating of confectionery, for decoration of chocolates, and in liqueurs [1]. It is commercially distributed in its pristine powder and sheet form, and in confectionery products. Due to its nature, E174 may contain silver nanoparticles, which implies a need for validated methods to size and quantify these particles. Single particle inductively coupled plasma-mass spectrometry (spICP-MS) is thereby a promising technique as it is capable of sizing and counting particles at the same time. A sp…
