Yes — Classic Mayo is ultra-processed.

The ingredient list is valid. This product is classified as ultra-processed (UPF) because it contains several industrial additives and formulations: xanthan gum (a stabiliser/thickener), antioxidant E392, and flavourings. These additives are characteristic of NOVA Group 4 ultra-processed foods. While basic ingredients like rapeseed oil, eggs, vinegar, salt, and sugar are not UPF by themselves, the presence of these industrial additives makes the overall product UPF.
