Yes — classic pesto is ultra-processed.
The ingredient list is valid. The product is classified as ultra-processed because it contains an acidity regulator (glucono delta lactone), which is an industrial additive and thus makes the overall product UPF under NOVA. The other ingredients are minimally processed or basic culinary ingredients, but the presence of this additive is sufficient for UPF classification.
Other sauces, condiments & spreads Nomi has checked — these ones aren't ultra-processed.

Yes — classic pesto by Filippo Berio is ultra-processed, so it counts as a UPF (ultra-processed food). The ingredient list is valid. The product is classified as ultra-processed because it contains an acidity regulator (glucono delta lactone), which is an industrial additive and thus makes the overall product UPF under NOVA. The other ingredients are minimally processed or basic culinary ingredients, but the presence of this additive is sufficient for UPF classification.
Ultra-processed foods (UPFs) are industrial formulations made with ingredients and additives you wouldn't find in a home kitchen — such as emulsifiers, artificial flavourings, colourings and modified starches. The classification is based on the NOVA system used by researchers and dietitians worldwide.
