Yes — Sardines in tomato sauce is ultra-processed.
Classified as ultra-processed because the ingredient list includes “flavouring,” which is an industrially produced additive/flavouring agent according to NOVA criteria. Other ingredients like sardines, tomato purée, sunflower oil, salt water, and sugar are not UPF by themselves, but the presence of industrial flavouring makes the overall product UPF.
